Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

It should be noted that, in the prior art, under the condition of performing program control according to a preset flow, in order to realize long-term stable combustion temperature control, the requirement on the operator is high, that is, the feeding amount and the corresponding air induction amount in each mode need to be manually and accurately set according to the current combustion condition, and at the same time, the mode parameters must be frequently changed to achieve a stable combustion condition, so that the operation of the operator is complicated. Moreover, the problems of too much or too little feeding and too much or too little induced air are inevitably caused by manual operation. Therefore, the embodiment of the invention provides a control method of a hot air stove, so as to realize intelligent control of the hot air stove.

fig. 1 is a flowchart of a method for controlling a hot air oven according to an embodiment of the present invention, where the method is applicable to automatically control current operating parameters of peripheral devices corresponding to a target hot air oven, and the method can be executed by a control system of the hot air oven, where the method can be implemented by hardware and/or software, and can be generally integrated in the control system of the hot air oven.

As shown in fig. 1, the method specifically includes the following steps:

And S110, acquiring the current combustion mode and the current temperature parameter of the target hot air stove.

Wherein the current temperature parameters include: flue gas temperature and furnace temperature. It should be noted that the flue gas temperature and the furnace temperature are both parameters used for characterizing the combustion characteristics in the furnace. Wherein, the higher the furnace temperature, then correspondingly, the higher the flue gas temperature is, thus the more the heat that is taken away. For example, when the temperature of the flue gas is ultrahigh and the temperature of the furnace is also ultrahigh, the combustion in the furnace is too violent, and a large amount of heat is discharged into the flue gas.

The current combustion mode is used for representing the current adopted control mode of the target hot air stove. In an embodiment, the combustion mode may include an automatic mode and a manual mode. Specifically, in an automatic mode, a user can set the ambient temperature so that a control system of the hot air stove can automatically calculate the optimal feeding amount and the optimal induced air amount according to the current temperature parameter, and the effects of energy conservation, environmental protection and constant temperature are ensured to be achieved; under the manual mode, the control system of the hot air stove can automatically adjust the air guiding quantity according to the manually set feeding quantity, so that the fuel can be fully combusted, and the purposes of energy conservation and environmental protection are ensured to be achieved.

and S120, determining a corresponding control adjustment strategy according to the current combustion mode and the current temperature parameter.

The control adjustment strategy can be understood as representing the corresponding final target feeding amount and the final target induced air amount under different current combustion modes and current temperature parameters. Wherein the feeding amount refers to the amount of fuel put into a hearth of the target hot air furnace; the induced air amount refers to an amount of flue gas extracted from a furnace of the target hot-air furnace. It should be understood that, under the condition of increasing the feeding amount and the air guiding amount at the same time, the combustion speed of the target hot air furnace is increased, so as to achieve the effect of increasing the temperature of the hearth and the temperature of the flue gas, i.e. achieve the purpose of accelerating heating. In the actual operation process, the magnitude of induced draft volume is adjusted to the working strength of accessible adjustment draught fan, and the working strength of draught fan is the bigger promptly, and then the induced draft volume is just bigger.

In the embodiment, the process of determining the corresponding control adjustment strategy according to the current combustion mode and the current temperature parameter is a process of performing closed-loop control on the target hot air stove. In the interim, closed-loop control refers to a control relationship in which the controlled output is returned to the input as control in a manner that exerts a controlling influence on the input. In the embodiment, the output of the flue gas temperature and the hearth temperature is returned to the input end of the target hot air furnace, and the process of controlling the feeding amount and the induced air amount of the target hot air furnace is controlled according to the flue gas temperature and the hearth. Of course, when the target hot-air stove employs different combustion modes, the corresponding control adjustment strategies are also different. Under the condition that the current combustion mode is the automatic mode, because the environmental temperature set by a user is fixed, namely the environmental temperature is ensured to be constant, the feeding quantity and the air guiding quantity need to be adjusted simultaneously, namely the feeding quantity and the air guiding quantity need to be adjusted simultaneously according to the current combustion mode and the current temperature parameter; under the condition that the current combustion mode is the manual mode, different working gears can be set for the target hot air stove in the manual mode, and a mapping relation is set between the working gears and the feeding amount in advance, namely the feeding amount of the target hot air stove is determined after the working gear of the target hot air stove is selected, at the moment, in order to ensure sufficient fuel of the fuel, the air induction amount can be adjusted according to the current combustion mode and the current temperature parameter, so that the sufficient combustion of the fuel is ensured through the size of the air induction amount.

and S130, automatically adjusting the current working parameters of the peripheral equipment corresponding to the target hot air furnace according to the control adjustment strategy.

In an embodiment, after determining a control adjustment strategy corresponding to the target hot air furnace according to the current combustion mode and the current temperature parameter, the current operating parameter of the peripheral device corresponding to the target hot air furnace may be automatically adjusted according to the control adjustment strategy, so as to adjust the feeding amount and the induced air amount. The peripheral device refers to a device configured by the target hot air furnace itself. In an embodiment, the peripheral device may include: a blower, a draught fan, an igniter and the like. The air blower is arranged at the head end of the boiler corresponding to the target hot air stove and used for feeding air to the boiler from the air door; the induced draft fan is arranged at the tail end of the boiler corresponding to the target hot air furnace and used for extracting hot flue gas in the hearth; the igniter is used for providing enough energy to ignite the fuel in the hearth at a moment and stabilizing the flame. When the control and adjustment strategies of the target hot air furnace are different, the current working parameters of the corresponding peripheral equipment are also different. For example, when the flue gas temperature and the furnace temperature of the target hot air furnace are too high, the corresponding control and adjustment strategy is to reduce the induced air volume, that is, the current working parameters corresponding to the induced draft fan need to be adjusted to reduce the flow of air in the furnace, so as to slow down the combustion speed of the fuel.

it should be noted that, while the air guiding amount is reduced, the purpose of reducing the air flow in the furnace chamber can be achieved by reducing the blast volume, so as to slow down the combustion speed of the fuel.

According to the technical scheme of the embodiment, the corresponding control adjustment strategy is determined by automatically carrying out logic judgment on the current combustion mode and the current temperature parameter, and the current working parameters of the peripheral equipment are automatically adjusted according to the control adjustment strategy, so that the closed-loop control of the target hot air stove is realized, and further, the sufficient combustion and the smokeless emission of fuel are realized.

Fig. 2 is a flowchart of another method for controlling a hot air furnace according to an embodiment of the present invention. Based on the above embodiments, in the present embodiment, when the current combustion mode is the manual mode, the corresponding control adjustment strategy is determined according to the current combustion mode and the current temperature parameter, and the current operating parameters of the peripheral devices corresponding to the target hot air stove are automatically adjusted according to the control adjustment strategy, which is further described. As shown in fig. 2, the method specifically includes the following steps:

s210, acquiring a current combustion mode and a current temperature parameter of the target hot air stove.

Wherein the current temperature parameters include: flue gas temperature and furnace temperature.

And S220, acquiring the current working gear of the target hot air stove.

the current working gear is used for representing the currently adopted working gear of the target hot air stove. Wherein, every target hot-blast stove can be provided with a plurality of work shifts to, the feeding volume that different work shifts correspond is also different. For example, it is assumed that each target hot air furnace can be set to a large range, a medium range and a small range, wherein the large range corresponds to the maximum feeding amount, and the small range corresponds to the minimum feeding amount. It can be understood that after the target hot air furnace determines the selected operating range, the corresponding feeding amount is determined.

and S230, determining a corresponding target feeding amount according to the current working gear.

wherein, a mapping relation is configured between the working gear and the feeding amount in advance. In an embodiment, after the current working gear of the target hot air furnace is determined, the target feeding amount corresponding to the current working gear can be determined according to a mapping relation between the preset working gear and the feeding amount. Wherein, the bigger the current work gear is, the more the corresponding target feeding amount is.

And S240, automatically matching the corresponding final target induced air volume according to the target feeding volume and the current temperature parameter.

It should be noted that, when the current combustion mode is the manual mode, the corresponding target feeding amount is automatically determined according to the current working gear pre-configured for the target hot air furnace, that is, the target feeding amount is related to the current working gear, that is, to ensure sufficient combustion of the fuel in different combustion modes, the corresponding final target induced air amount needs to be automatically matched according to the target feeding amount and the current temperature parameter.

Wherein, step S240 includes S2401-S2402:

S2401, automatically matching corresponding intermediate target induced air volume according to the target feeding volume.

The intermediate target induced air volume can be understood as the induced air volume automatically matched according to the target feeding volume. It should be understood that, after the current working gear of the target hot air furnace is determined, the corresponding target feeding amount can be automatically matched according to the current working gear, and an intermediate target induced air volume can be automatically matched according to the target feeding amount, so that the fuel with the target feeding amount can be fully combusted through the intermediate target induced air volume. At this time, due to the change of the current temperature parameter of the target hot air furnace, the intermediate target index air volume needs to be adjusted to ensure that the peripheral equipment corresponding to the target hot air furnace is within the normal operation range, so as to avoid the damage of the peripheral equipment.

S2402, under the condition that the current temperature parameter exceeds the preset temperature range, automatically adjusting the intermediate target induced air volume to obtain the corresponding final target induced air volume.

the preset temperature range refers to a temperature range that ensures that the peripheral devices are not damaged and that ensures that the target hot air furnace is in the optimal combustion state, and may also be referred to as a theoretical optimal temperature range. It should be noted that, the current temperature parameters include the flue gas temperature and the furnace temperature, and the corresponding preset temperature ranges refer to a theoretical optimal flue gas temperature range and a theoretical optimal furnace temperature range. In the actual operation process, the furnace temperatures corresponding to different positions in the furnace are also different, for example, the furnace temperature corresponding to the middle of the furnace is at the maximum value, and the furnace temperature corresponding to the edge of the furnace is at the minimum value, so as to ensure the accuracy of the obtained final target induced air volume, in the embodiment, the adjustment process of the intermediate target induced air volume may be described by taking the current temperature parameter as the flue gas temperature as an example. It is understood that the preset temperature range refers to a theoretically optimal flue gas temperature range.

Exemplarily, when the flue gas temperature is lower than the theoretical optimal flue gas temperature range and the furnace temperature is also correspondingly lower, it can be judged that the fuel combustion in the furnace is insufficient, the intermediate target induced air volume needs to be increased to obtain the corresponding final target induced air volume, and then whether the final target induced air volume meets the optimal matching requirement is continuously judged through the corresponding change of the flue gas temperature; on the contrary, when the flue gas temperature is higher than the theoretical optimal flue gas temperature range and the furnace temperature is correspondingly higher, the combustion of the fuel in the furnace can be considered to be more violent, and under the condition that the flue gas temperature exceeds the optimal theoretical flue gas temperature range, the intermediate target induced air quantity needs to be reduced. Of course, when the temperature of the flue gas exceeds the optimal theoretical range of the temperature of the flue gas, the amount of the hot air blown by the hot air blower needs to be increased while the amount of the intermediate target induced air is reduced, so that the heat can be taken away as soon as possible.

and S250, automatically adjusting the current working parameters of the peripheral equipment corresponding to the target hot air furnace according to the target feeding amount and the final target induced air amount.

in the embodiment, after the final target induced air volume and the target feeding volume are determined, the current working parameters of the peripheral equipment corresponding to the target hot-blast stove can be automatically adjusted according to the target feeding volume and the final target induced air volume, that is, the current working parameters of the induced draft fan are correspondingly adjusted, so that the effect of intelligently controlling the current working parameters of the peripheral equipment according to the current temperature parameters in a manual mode is realized.

according to the technical scheme of the embodiment, on the basis of the above embodiment, the corresponding target feeding amount is determined according to the current combustion mode of the target hot air stove in the manual mode, and the corresponding final target induced air volume is automatically matched according to the target feeding amount and the current temperature parameter, so that the fuel can be fully combusted at different manual current working gears, and the technical effects of energy conservation and environmental protection are achieved.

Fig. 3 is a flowchart of a control method for a hot air stove according to another embodiment of the present invention. Based on the above embodiments, in the case that the current combustion mode is the automatic mode, the present embodiment further describes determining a corresponding control adjustment strategy according to the current combustion mode and the current temperature parameter, and automatically adjusting the current operating parameters of the peripheral devices corresponding to the target hot air stove according to the control adjustment strategy.

As shown in fig. 3, the method comprises the steps of:

and S310, acquiring the current combustion mode and the current temperature parameter of the target hot air stove.

Wherein the current temperature parameters include: flue gas temperature and furnace temperature.

And S320, determining a comparison result between the current environment temperature and a preset target environment temperature.

the target ambient temperature refers to a temperature to be reached by the target hot air furnace. It should be noted that the target hot air stove may be generally used for heating, and in order to ensure a constant indoor temperature, after the user starts the target hot air stove, the user may set a temperature to be reached by the target hot air stove, that is, a target ambient temperature, according to the user's own needs. Then, the control system of the hot air furnace compares the current ambient temperature of the target hot air furnace with the target ambient temperature to obtain a corresponding comparison result.

And S330, automatically matching the corresponding final target feeding amount and the final target induced air amount according to the comparison result and the current temperature parameter.

In an embodiment, after the comparison result between the current ambient temperature and the target ambient temperature is obtained, the corresponding final target feeding amount and the final target induced air amount can be automatically matched according to the comparison result and the current temperature parameter.

specifically, step S330 includes S3301 to S3302:

And S3301, automatically matching corresponding middle target feeding amount and middle target induced air amount according to the comparison result.

in the embodiment, under the condition that the current environment temperature is lower than the preset target environment temperature, the combustion of fuel in a hearth of the target hot air furnace can be increased and accelerated, so that the target hot air furnace generates more heat, and further the current environment temperature reaches the target environment temperature, namely the current feeding amount needs to be increased, so as to reach the intermediate target feeding amount; and increasing the current induced air quantity to achieve the intermediate target induced air quantity. Namely, the fuel quantity in the hearth is increased, the air flow in the hearth is accelerated, and the rapid combustion of the fuel in the hearth is accelerated; on the contrary, when the current environment temperature is higher than the preset target environment temperature, it indicates that the current environment temperature needs to be reduced, and the combustion of the fuel in the hearth of the target hot air furnace can be slowed down, so as to reduce the heat generated by the target hot air furnace, that is, the current feeding amount and the current air induction amount of the target hot air furnace are reduced, so as to obtain the corresponding intermediate target feeding amount and the intermediate target air induction amount.

And S3302, automatically adjusting the intermediate target feeding quantity and the intermediate target induced air quantity to obtain a corresponding final target feeding quantity and a corresponding final target induced air quantity under the condition that the current temperature parameter exceeds a preset temperature range.

In the embodiment, in order to achieve the effect that the current ambient temperature reaches the target ambient temperature, the current feeding amount and the current induced air amount may be respectively adjusted to the intermediate target feeding amount and the intermediate target induced air amount. In the actual operation process, the current environment temperature reaches the target environment temperature, and meanwhile, the fuel in the hearth is ensured to be fully combusted, namely, the intermediate feeding amount and the intermediate target induced air volume are automatically adjusted according to the comparison result of the current temperature parameter of the target hot air stove and the preset temperature range, so that the corresponding final target feeding amount and the final target induced air volume are obtained.

it should be noted that, when the current combustion mode is the automatic mode, the target hot air stove first determines a current operating gear according to the manual mode to determine the corresponding feeding amount and the induced air amount. Then, a user can set a target environment temperature to determine corresponding intermediate target feeding amount and intermediate target induced air volume according to the comparison result of the current environment temperature and the target environment temperature; and then, according to the comparison result of the current temperature parameter and the preset temperature range, adjusting the intermediate target feeding quantity and the intermediate target induced air quantity to obtain the corresponding final target feeding quantity and final target induced air quantity.

And S340, automatically adjusting the current working parameters of the peripheral equipment corresponding to the target hot air furnace according to the final target feeding amount and the final target induced air amount.

in the embodiment, after the final target feeding amount and the final target induced air amount are determined, the current working parameters of an induced draft fan corresponding to the target hot air furnace are adjusted according to the final target feeding amount and the final target induced air amount so as to reduce or increase the size of the induced air amount; and controlling the throwing speed of the batch feeder to reduce or increase the feeding amount.

According to the technical scheme of the embodiment, on the basis of the embodiment, a comparison result of the current environment temperature and the preset target environment temperature is determined in an automatic mode; and automatically matching the corresponding final target feeding quantity and the final target induced air quantity according to the comparison result and the current temperature parameter, ensuring that the optimal final target feeding quantity and the final target induced air quantity are automatically calculated according to the current temperature parameter, and ensuring that the temperature is constant while energy-saving and environment-friendly sufficient combustion is realized.

fig. 4 is a flowchart of a control method for a hot air stove according to another embodiment of the present invention. In the present embodiment, a control method of the hot air oven will be further described based on the above embodiments. Specifically, as shown in fig. 4, the method includes the following steps:

And S410, automatically detecting the current operating conditions of the temperature sensor and the peripheral equipment corresponding to the target hot air stove to obtain a self-detection result.

In the embodiment, after a control system of the hot air furnace is powered on, the current operating conditions of the temperature sensor and the peripheral equipment corresponding to the target hot air furnace are automatically obtained through the data acquisition converter, and the current operating conditions are sent to the data logic operation analysis processor, so that the operating conditions of the temperature sensor and the peripheral equipment are automatically detected, and whether each component in the target hot air furnace is normal or not is ensured.

And S420, displaying the self-checking result to a display device of the target hot air stove.

wherein, the self-checking result refers to the checking result of the temperature sensor and the peripheral equipment in the target hot air stove. In an embodiment, after determining the detection results of the respective temperature sensors and the peripheral devices, the detection results may be displayed on a display device of the target hot air oven in order to facilitate a user to view the detection results. The display device can be a display screen or an indicator lamp.

and S430, displaying the fault processing strategy to a display device of the target hot air furnace.

Of course, in the actual detection process, there may be a case where the temperature sensor or the peripheral device in the target hot air oven is out of order.

It should be noted that, steps S410 to S430 may be executed before step S440, but in the actual operation process, in order to ensure the normal operation of the control system of the hot air oven, the automatic detection and early warning process may also be performed on the control system of the hot air oven according to the operation feedback of the temperature sensor and the peripheral device, that is, after step S460, steps S410 to S430 may be executed again, so as to avoid the situation that the control system of the hot air oven is still executed according to the established procedure and the early warning and automatic correction cannot be performed in time under the condition that the flame is extinguished or the glass observation window is burned out, thereby ensuring the personnel safety and avoiding the economic loss.
