The invention belongs to the field of civil heating devices, and particularly relates to a filter plate and a heating device with the filter plate.

Background

At present, the civil heating furnace mainly comprises an electric heating furnace, a fuel oil and gas heating furnace, a coal-fired heating furnace and the like, wherein the coal-fired heating furnace is economical and practical, and is an ideal choice for urban and rural junctions and vast rural areas which do not have central heating and gas heating conditions and have low heating cost.

China carries out a perfect grading system on coal, including coal calorific value grading, phosphorus grading, sulfur grading and the like, and different grades of coal have different combustion characteristics. In the prior art, different combustion-supporting modes are not recorded for different fire coals. In the prior art, a vertical coal-fired normal-pressure hot water boiler mainly comprises a boiler shell end enclosure, a boiler liner top, a lower sealing ring, a cupola pipe and a transverse water pipe, wherein a combustion chamber is arranged in the boiler liner, fuel is combusted on a fixed grate, the natural ventilation is realized, smoke transversely erodes the transverse water pipe in the boiler liner, and the smoke is discharged into the atmosphere through the cupola pipe and a chimney.

The invention patent of the applicant's application "a heating device using solid fuel, application No. 202010355983.6" discloses: the air distribution system realizes independent adjustable air supply of the upper path and the lower path, controls the furnace temperature in a reasonable interval, can obviously improve the combustion efficiency, and can accurately adjust the oxygen content in the hearth, thereby ensuring that the furnace is always in an optimal combustion state, and realizing better combustion efficiency and better emission reduction effect.

Through trial and error, the applicant also found new problems:

1. the smoke at the top of the hearth is discharged through an original smoke discharging system, and the smoke dust, tar and the like generated by combustion are included in the discharging path of the smoke discharging system, the smoke dust and tar are easily adhered to the inner wall of the hearth or a smoke discharging pipeline, the heating device is not favorable for continuous good work and subsequent pipeline cleaning, and the risk of polluting indoor air also exists.

2. In the intermittent feeding process, the temperature at the top of the hearth can be dissipated in a short time, so that the temperature at the top of the hearth is not stable enough, and the ignition point of coal-fired coal gas is easy to be insufficient.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the heating device with the filter plate and the filter plate is provided to improve the overall performance of the heating device, including flue gas filtration, dust adsorption, temperature control at the top of the hearth and tar secondary combustion.

The scheme can realize the filtration of smoke and the adsorption of dust by arranging the filter plate, and the secondary combustion can also be realized when tar is adsorbed on the filter plate; because the filter self has the heat, this heat can not scatter and disappear too fast in the intermittent type process of feeding again to can realize the effect of furnace top accuse temperature, in addition at periodic intermittent type process of refueling, can handle the filter deashing as required, further be favorable to the heating device to last good work and the cleanness of follow-up pipeline, also further reduce the risk of polluting the room air.

Preferably, the filter plate is located above the upper air distribution device. The position of this scheme lies in directly over the flame district, does not influence the air distribution device simultaneously and to the inside air distribution of furnace, and the filtration adsorption effect of filter obtains fully ensureing, is favorable to the accuse temperature simultaneously.

Preferably, the filter plate is a flat plate as a whole or a convex plate including a convex portion in the middle. Wherein, the flat scheme is easy to process and form or replace by honeycomb ceramics; the scheme that the middle part includes the protruding board of bellying can furthest reduce the filter itself to the influence of the interior sufficient combustion effect of furnace, increases adsorption area and adsorption effect simultaneously, and flue gas exhaust angle is more level and smooth, is unlikely to produce the palirrhea phenomenon of flue gas.

Preferably, when the filter plate is integrally a convex plate including a convex portion at a middle portion, the convex portion is one or more. The scheme that the bellying is one easily machine-shaping, the number of filtration pore is many on the filter, and adsorption effect and heat preservation effect are more excellent.

Preferably, when the number of the convex parts is one, the axial lines of the filter holes uniformly distributed on the convex parts are obliquely diffused outwards from the center. The scheme is further favorable for smooth discharge of the flue gas, and the adsorption effect and the heat preservation effect are better.

Preferably, the size of the orifice of one side of the filter hole close to the flame area is larger than that of the orifice of one side close to the smoke exhaust port. This scheme temperature control effect is more excellent, covers the bell in the twinkling of an eye after intermittent type is reinforced and can reduce furnace top temperature difference to the temperature is more stable in the further guarantee furnace.

The invention also discloses a heating device matched with the filter plate. The heating device provided with the filter plate has better smoke filtering effect, better indoor air quality, more sufficient fuel combustion and less influence of intermittent feeding on the temperature fluctuation of the hearth.

Preferably, the furnace roof comprises a support site on which the filter plate is placed. The structure of this scheme is simple and easy, and is with low costs.

Preferably, the filter plate is detachably connected to the bottom of the furnace cover. This scheme more is favorable to the clearance reinforced, also is convenient for clean the maintenance filter.

Preferably, the furnace comprises an ignition device, and an ignition part of the ignition device is positioned at the upper part of the furnace and below the upper air distribution device. The scheme can further resist the risk that the ignition point on the upper part of the hearth is insufficient due to sudden temperature drop on the upper part of the hearth after intermittent feeding.

Compared with the prior art, the invention can generally obtain the following technical effects:

the filter plate and the heating device with the filter plate improve the overall performance of the heating device, and when the flue gas at the top of the hearth is discharged through an original smoke discharging system, the filter plate is arranged to filter the flue gas and adsorb dust, and tar is adsorbed on the filter plate to realize secondary combustion; because the filter self has the heat, this heat can not scatter and disappear too fast in the intermittent type charging process again, thereby can realize the effect of furnace top accuse temperature, in addition at periodic intermittent type fueling in-process, can handle the filter deashing as required, further be favorable to the heating plant to last good work and the cleanness of follow-up pipeline, also further reduced the risk of polluting the room air and greatly reduced the energy and scatter and disappear, reduced the influence of furnace upper portion temperature shock to the burning effect in the stove in the intermittent type charging process, make heating plant fuel utilization rate higher, the heating effect is better.
