Abstract

The utility model relates to a kiln smokeless combusting device which is composed of a refractory carbonization coking chamber wall, a smoke removing wall, a fire grate, a bellows/ dust pool and a coal adding/ fire poking opening cover. The utility model can be used for vitreous enamel firing furnaces, ceramic firing furnaces, annealing furnaces, heat air drying furnaces, heating furnaces and other kilns which use coal as fuel. The kilns using coal as fuel can not only has a positively combustion chamber, but also has a carbonization coking chamber used for carbonization and coking by using the utility model, and the kiln can realize real smokeless combustion. The utility model has the advantages of simple structure, low concentration of smoke exhaust, low blackness, high thermal efficiency and energy source saving, and the utility model is especially suitable for the technical innovation of the existing kilns using coal as fuel.

Description

The stove smokeless combustion device

The utility model relates to a kind of stove smokeless combustion device, and can be widely used in enamel firing furnace, ceramic firing furnace, annealing furnace, hot-air drying stove, heating furnace etc. is the stove of fuel with the coal.

In the prior art, the enamel firing furnace, the pottery firing furnace, annealing furnace, hot-air drying stove, heating furnaces etc. are the stove of fuel with the coal, generally all only have and just burning the combustion chamber, fuel is directly sent into so just burning combustion chambers burn, the fuel combustion required air is entered through fire grate by ashpit, owing to having little time to burn fully again, the carbon monoxide that carbon and imperfect combustion produced in the flue gas that exists fuel combustion to generate just enters the drawback of flue, thereby the dust concentration of discharging fume mostly is big, the blackness height, even the dust emission standard that has all surpassed national regulation is more than five times, not only environment is caused severe contamination, but also because fuel combustion is incomplete, the thermal efficiency is low, waste a large amount of energy.

It is the smokeless combustion device of fuel stove with the coal that the purpose of this utility model is to provide a kind of enamel firing furnace, ceramic firing furnace, annealing furnace, hot-air drying stove, heating furnace etc. of being widely used in.

The purpose of this utility model can realize by such technical scheme: this enamel firing furnace, ceramic firing furnace, annealing furnace, hot-air drying stove, the heating furnace etc. of being widely used in are the smokeless combustion device of fuel stove with the coal, it comprises the following bellows/ashpit that is provided with of fire-resistant destructive distillation coking locular wall, smoke elimination wall, fire grate, fire grate and has sees that fire spies on the coal/flap that pokes fire of door, and what the destructive distillation cooking camber that fire-resistant destructive distillation coking locular wall becomes with the smoke elimination circummure had upper coal feeding/poke fire mouthful, a rear wall indwelling is just burning the port of combustion chamber with the stove of desire use.This stove smokeless combustion device, be arranged on the original front side of just burning the combustion chamber of stove, the port that the destructive distillation cooking camber that makes smokeless combustion device is kept somewhere by its rear wall communicates with the original combustion chamber of just burning of stove, like this, stove just burns the combustion chamber with regard to not only having, but also had the destructive distillation cooking camber that is used for fuel destructive distillation coking, such stove, fuel is admitted to the destructive distillation cooking camber of setting earlier, in the destructive distillation cooking camber, fuel is by just burning the radiant heat destructive distillation coking of combustion chamber, just be admitted to the just burning combustion chamber internal combustion of stove after the destructive distillation coking again, and carbon and carbon monoxide in the flue gas that fuel is produced in destructive distillation coking, then because the effect of the smoke elimination wall that is provided with, after the burning in the destructive distillation cooking camber, remaining part just enters stove downwards with flue gas and is just burning in the combustion chamber, the process stove is just burning the red-hot fire bed in the combustion chamber, make that the carbon monoxide that carbon and imperfect combustion produced of remaining part obtains burning fully again in the flue gas, such stove, again because its coal that is the destructive distillation coking that is just burning the combustion chamber internal combustion, thereby the temperature of just burning the combustion chamber can significantly improve.

Above-mentioned smokeless combustion device, its smoke elimination wall also can replace by the original front side wall that is just burning the combustion chamber of stove.

This stove smokeless combustion device provided by the utility model; simple in structure; can be widely used in the enamel firing furnace; the pottery firing furnace; annealing furnace; hot-air drying stove; heating furnaces etc. are the stove of fuel with the coal; use this device; with the coal is that the fuel stove just burns the combustion chamber with regard to not only having; but also had the destructive distillation cooking camber that is used for fuel destructive distillation coking; such stove need not installed other any smoke abatement device can realize real smokeless combustion; the smoke evacuation dust concentration is low; blackness is low; the one-level dust emission standard that is better than a class environment protection zone of national regulation; has thermal efficiency height; it is the technological transformation of fuel stove with the coal that the advantage of energy savings, this device are specially adapted to existing.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail:

The stove smokeless combustion device application examples schematic diagram that Fig. 1 is provided for the utility model embodiment.

The fire grate structure schematic diagram of the stove smokeless combustion device that Fig. 2 is provided for the utility model embodiment.

Fig. 3 is the A-A cutaway view of Fig. 2.

With reference to accompanying drawing, this stove smokeless combustion device that the utility model embodiment is provided, it comprises fire-resistant destructive distillation coking locular wall 5 and heat-insulation layer 9 and steel outer casing 10, smoke elimination wall (replacing) 1 with the original front side wall that is just burning the combustion chamber of stove, the preceding high then low fire grate of settling 11, the fire grate 11 following steel bellows/ashpits 14 that are provided with, have and see that fire spies on door 7 the coal/flap 6 that pokes fire, the destructive distillation cooking camber 12 that its fire-resistant destructive distillation coking locular wall 5 and smoke elimination wall 1 surround has upper coal feeding/poke fire mouthfuls 8, the stove with the desire use that rear wall is kept somewhere is just burning the port 18 of combustion chamber 19; It has sees that fire spies on door 7 the coal/flap 6 that pokes fire and have pull rope 2 and a pulley 3 and an open operation device that is configured to thereof, and is provided with at destructive distillation cooking camber 12 upper coal feedings/mouthful 8 places that poke fire by the guide rail 4 that slides that is provided with on destructive distillation cooking camber 12 upper side walls; Its fire grate 11 is provided with and constitutes with the coal stove row bar 11b that turns over that fixed grate bar 11a is distributed in distance by fixed grate bar 11a with by crankshaft-link rod operating mechanism 15, and described crankshaft-link rod operating mechanism 15 is by handle, bent axle 15a, crankshaft base 15b and be connected the connecting rod 15c that turns over coal stove row bar 11b and constitute.This stove smokeless combustion device, be arranged on the front side that existing enamel firing furnace is just burning the combustion chamber, the destructive distillation cooking camber 12 of smokeless combustion device promptly communicates with the just burning combustion chamber 19 of existing enamel firing furnace by the port 18 that its rear wall is kept somewhere, and promptly finishes the technological transformation of existing enamel firing furnace.Among the figure, 13---shoot door, 16---ajutage, 17---ash tube.
