The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The method for microwave pyrolysis treatment of electronic waste provided by the embodiment of the present invention is applied to an apparatus for microwave pyrolysis treatment of electronic waste, and an execution main body of the method for microwave pyrolysis treatment of electronic waste is a controller in the apparatus for microwave pyrolysis treatment of electronic waste, as shown in fig. 1, a schematic flow diagram of the method for microwave pyrolysis treatment of electronic waste is provided, and the steps included in the method are specifically described below with reference to fig. 1.

S101, obtaining target characteristic parameters in the equipment for microwave pyrolysis treatment of the electronic waste.

Wherein, the target characteristic parameter can include the current concentration of the current gas of the current temperature of first current temperature in the microwave pyrolysis intracavity, the current temperature of second in the microwave treatment intracavity and/or outlet duct department, and the equipment of microwave pyrolysis processing electronic waste can be used for handling waste circuit board, electronic waste, various solid wastes etc. high-efficiently and fast for meeting emission standard's clean gas, various prills and have the carbon particle of better adsorptivity.

Specifically, a sensor may be disposed in the apparatus for microwave pyrolysis treatment of electronic waste, and the sensor may be configured to detect a first current temperature in the microwave pyrolysis chamber, a second current temperature in the microwave treatment chamber, and/or a current concentration of a current gas at the outlet pipe, and send the detected first current temperature, second current temperature, and/or current concentration to the controller. Accordingly, the controller may receive a first current temperature within the microwave pyrolysis chamber, a second current temperature within the microwave treatment chamber, and/or a current concentration of the gas present at the outlet duct, as detected by the sensor.

In addition, the controller can obtain the first current temperature in the microwave pyrolysis cavity, the second current temperature in the microwave treatment cavity and/or the current concentration of the current gas at the gas outlet pipe separately, or at least two of the first current temperature, the second current temperature and the current concentration of the current gas at the gas outlet pipe simultaneously. And is not particularly limited herein.

And S102, determining a target processing strategy matched with the target characteristic parameters.

Specifically, when receiving the target characteristic parameters sent by the sensor, the controller may further match the target characteristic parameters with preset target characteristic information, so as to obtain a target processing strategy matched with the target characteristic parameters; when the target characteristic parameter includes a first current temperature in the microwave pyrolysis cavity, a second current temperature in the microwave treatment cavity, and/or a current concentration of a current gas at the gas outlet pipe, the preset target characteristic information may include a first preset reference temperature, a second preset reference temperature, and/or a preset reference concentration.

Therefore, when the target characteristic parameter includes a first current temperature in a microwave pyrolysis chamber of the apparatus for microwave pyrolysis treatment of electronic waste, the step S102 may be implemented by the following sub-steps:

and S1021, matching the first current temperature with a first preset reference temperature to obtain a first target matching result.

The first preset reference temperature can be used for representing that the temperature in the microwave pyrolysis cavity can be normally used for heating and cracking the electronic waste. The first preset reference temperature may be a first reference temperature threshold, or may be a first reference temperature range. This is not a limitation here.

Specifically, when the controller acquires the first current temperature in the microwave pyrolysis cavity via the sensor, the first current temperature may be further matched with a first preset reference temperature, for example, the first current temperature is compared with a first reference temperature threshold, or the first current temperature is respectively compared with a minimum value and a maximum value of a first reference temperature range, so as to obtain a first target matching result.

Step S1022, when the first target matching result indicates that the first current temperature is higher than the first preset reference temperature, determining a target processing strategy including reducing microwave power.

Specifically, when the controller determines that the first target matching result represents that the first current temperature in the microwave pyrolysis cavity is higher than the first preset reference temperature, the controller may determine that the current temperature in the microwave pyrolysis cavity is too high and cannot be normally used for heating and pyrolyzing the electronic waste, and may even damage equipment, and at this time, the controller may determine a target processing strategy including reducing microwave power, so as to achieve the purpose of normally heating and pyrolyzing the electronic waste on the premise of protecting the microwave pyrolysis cavity from being damaged and prolonging the service life of the microwave pyrolysis cavity; wherein the first current temperature in the microwave pyrolysis chamber being higher than the first preset reference temperature may include the first current temperature being greater than a first reference temperature threshold or the first current temperature being greater than a maximum value of a first reference temperature range.

And step S1023, when the first target matching result indicates that the first current temperature is lower than the first preset reference temperature, determining a target processing strategy comprising increasing microwave power.

Specifically, when the controller determines that the first target matching result represents that the first current temperature in the microwave pyrolysis cavity is lower than the first preset reference temperature, the controller may determine that the current temperature in the microwave pyrolysis cavity is too low and cannot heat the electronic waste to cracking to generate waste gas, and at this time, may determine a target treatment strategy including increasing microwave power, so that the microwave pyrolysis cavity can be normally used for heating and pyrolyzing the electronic waste; the first current temperature in the microwave pyrolysis chamber lower than the first preset reference temperature may include that the first current temperature is lower than a first reference temperature threshold, and the first current temperature is lower than a minimum value of a first reference temperature range.

It should be noted that, when the controller determines that the first current temperature in the microwave pyrolysis chamber is the same as the first reference temperature threshold or the first current temperature is between the minimum value and the maximum value of the first reference temperature range, it may be considered that the current temperature in the microwave pyrolysis chamber is moderate and can be normally used for heating and pyrolyzing the electronic waste, and at this time, the controller may directly control to perform pyrolysis and treatment operations on the electronic waste.

In the actual processing process, when the target characteristic parameter includes a second current temperature in the microwave processing cavity of the apparatus for microwave pyrolysis processing of electronic waste, the step S102 may be implemented by the following sub-steps:

and step S11, matching the second current temperature with a second preset reference temperature to obtain a second target matching result.

The second preset reference temperature can be used for representing that the temperature in the microwave treatment cavity can be used for normally burning waste gas and heating electronic garbage in the microwave pyrolysis cavity. The second preset reference temperature may be a second reference temperature threshold, or a second reference temperature range. And is not limited herein.

Specifically, when the controller acquires the second current temperature in the microwave processing cavity via the sensor, the controller may further match the second current temperature with a second preset reference temperature, for example, compare the second current temperature with a second reference temperature threshold or compare the second current temperature with a maximum value and a minimum value of a second reference temperature range, respectively, so as to obtain a second target matching result.

And step S12, when the second target matching result indicates that the second current temperature is higher than the second preset reference temperature, determining a target processing strategy comprising reducing fan blowing and reducing microwave power.

Specifically, when the controller determines that the second target matching result represents that the second current temperature in the microwave treatment cavity is higher than the second preset reference temperature, the temperature in the microwave treatment cavity is considered to be too high and the equipment is easy to burn, and at the moment, a target treatment strategy comprising reduction of fan blowing and reduction of microwave power can be determined, so that the temperature in the microwave treatment cavity can meet the purposes of burning treatment waste gas and heating electronic waste in the microwave pyrolysis cavity; wherein the second current temperature in the microwave processing chamber being higher than the second preset reference temperature may include the second current temperature being greater than a second reference temperature threshold or the second current temperature being greater than a maximum value of a second reference temperature range.

And step S13, when the second target matching result indicates that the second current temperature is lower than the second preset reference temperature, determining a target processing strategy comprising increasing microwave power and increasing fan blowing.

Specifically, when the controller determines that the second target matching result represents that the second current temperature in the microwave treatment cavity is lower than the second preset reference temperature, the controller may determine that the current temperature in the microwave treatment cavity is too low and cannot normally combust and treat the waste gas and heat the electronic waste in the microwave pyrolysis cavity, and at this time, may determine a target treatment strategy including increasing microwave power and increasing fan blowing so that the microwave treatment cavity can normally combust and treat the waste gas and heat the electronic waste; wherein the second current temperature in the microwave processing chamber being lower than the second preset reference temperature may include the second current temperature being lower than a second reference temperature threshold or the second current temperature being lower than a minimum value of a second reference temperature range.

It should be noted that, when the controller determines that the second current temperature in the microwave processing cavity is the same as the second reference temperature threshold or the second current temperature is between the minimum value and the maximum value of the second reference temperature range, it may be considered that the current temperature in the microwave processing cavity is moderate and can be normally used for burning the waste gas and heating the electronic waste, and at this time, the controller may directly control to perform the pyrolysis and processing operation on the electronic waste.

In the actual processing process, when the target characteristic parameter includes the current concentration of the current gas at the gas outlet pipe of the device for microwave pyrolysis treatment of electronic waste, the step S102 may be implemented by the following sub-steps:

and step S21, matching the current concentration with a preset reference concentration to obtain a third target matching result.

The preset reference concentration can be used for representing the concentration of organic waste gas molecules such as combustible gas, dioxin and the like in the gas, which indicates that the gas is clean gas which meets the emission standard and does not cause secondary pollution. The preset reference concentration may be a reference concentration threshold or a reference concentration range. And is not limited herein.

Specifically, when the controller obtains the current concentration of the current gas at the gas outlet pipe via the sensor, the current concentration may be further matched with a preset reference concentration, for example, the current concentration is compared with a reference concentration threshold value or the current concentration is respectively compared with the maximum value and the minimum value of a reference concentration range, so as to obtain a third target matching result.

And step S22, when the third target matching result indicates that the current concentration is higher than the preset reference concentration, determining a target processing strategy comprising increasing microwave power and increasing fan blowing.

Specifically, when the controller determines that the third target matching result represents that the current concentration of the current gas at the gas outlet pipe is higher than the preset reference concentration, the microwave treatment cavity can be considered to not treat the waste gas generated by cracking the electronic waste to the standard, and at the moment, a target treatment strategy comprising increasing microwave power and increasing fan blast can be determined, so that the purpose of quickly and efficiently treating all organic waste gas molecules contained in the waste gas generated by cracking the electronic waste is achieved; the current concentration of the current gas at the gas outlet pipe is higher than the preset reference concentration, and the current concentration may be higher than the reference concentration threshold or the maximum value of the reference concentration range.

And step S23, when the third target matching result indicates that the current concentration is lower than the preset reference concentration, determining a target processing strategy including exhausting the current gas.

Specifically, when the controller determines that the third target matching result represents that the current concentration of the current gas at the gas outlet pipe is lower than the preset reference concentration, the microwave treatment cavity can be considered to treat the waste gas generated by cracking the electronic waste into the gas which meets the emission standard and does not cause secondary pollution, and at the moment, a target treatment strategy including discharging the current gas can be determined, so that the clean gas generated after being treated by the equipment can be discharged in time; the current concentration of the current gas at the gas outlet pipe is lower than the preset reference concentration, and the current concentration may be less than or equal to a reference concentration threshold value, the current concentration is between a minimum value and a maximum value of a reference concentration range, or the current concentration is less than or equal to a minimum value of the reference concentration range.

In the actual processing process, when the target characteristic parameters acquired by the controller include at least two of a first current temperature in the microwave pyrolysis cavity, a second current temperature in the microwave processing cavity, and a current concentration of the current gas at the gas outlet pipe, matching the first current temperature with a first preset reference temperature, matching the second current temperature with a second preset reference temperature, and matching the current concentration with a preset reference concentration may be performed by two corresponding steps, so as to obtain at least two corresponding target matching results, thereby determining a target processing strategy corresponding to the at least two target matching results. The specific matching process is as described in the foregoing embodiments, and is not described herein again.

And step S103, controlling and executing target processing operation according to the target processing strategy.

In the actual processing procedure, step S103 can be realized by the following steps:

and step S1031, when a target processing strategy comprising adjusting fan blowing and adjusting microwave power is determined, controlling and adjusting the power of a microwave source on the outer wall of the top of the furnace body and adjusting the wind speed of an air inlet fan externally connected with the microwave processing cavity to obtain target adjusted information.

The target adjusted information may include adjusted power after the power of the microwave source is adjusted and adjusted wind speed after the wind speed of the air intake fan is adjusted.

Specifically, when the controller determines the target processing strategy including adjusting the fan blast and adjusting the microwave power, the temperature in the microwave processing cavity can be considered too high or too low, that is, the microwave processing cavity can not be used for burning processing waste gas and heating electronic garbage in the microwave pyrolysis cavity, at the moment, the controller can control to reduce the power of the microwave source on the outer wall of the top of the furnace body and reduce the wind speed of the external air inlet fan of the microwave processing cavity, or can control to increase the power of the microwave source on the outer wall of the top of the furnace body and increase the wind speed of the external air inlet fan of the microwave processing cavity, thereby obtaining the target adjusted information. Wherein, the flow rate of the water is controlled by the control unit.

Step S1032, under the action of the target adjusted information, controlling to execute a target pyrolysis treatment operation for the electronic waste entering the microwave pyrolysis cavity.

Specifically, when the controller obtains the target adjusted information, the controller can continue to control the equipment to perform pyrolysis and treatment operations on the electronic waste; wherein the target processing operation may comprise a target pyrolysis processing operation.
