Description

Honeycomb briquette fired environment-friendly heating stove

The utility model relates to coal heating stove, specifically a kind of honeycomb briquette fired environment-friendly heating stove that utilizes fume afterheat.

The existing heating stove thermal efficiency is low, and useless flue gas is gone in the atmosphere by flue is in line, and contained sulfur oxide etc. causes severe contamination to air in the coal smoke, and contained heat does not add being discharged from of utilization yet in the flue gas, causes the significant wastage of the energy.

The purpose of this utility model is the heating stove of realizing that a kind of thermal efficiency is high; Another purpose is to design the high and heating stove that can utilize institute's heat content in the flue gas of a kind of thermal efficiency; The environment-friendly heating stove that another purpose is to design a kind of thermal efficiency height, reduces exhaust emission.

The purpose of this utility model is achieved through the following technical solutions:

The heating stove main body comprises the furnace chamber of being with water jacket, it is characterized in that being provided with in the said furnace chamber the last coal basket and the following coal basket that load upper and lower two groups of fire coals respectively, be provided with central dividing plate between last coal basket and the following coal basket, the furnace chamber wall is provided with respectively and goes up accordingly smokejack and down smoke-discharging road with last coal basket and following coal basket, be connected with in line flue after last smokejack, down smoke-discharging road cross, intersection is provided with by timer-operated flue conversion valve plate.

The utility model can be provided with waste heat radiator and air-introduced machine on the basis of such scheme, further improve the thermal efficiency, concrete scheme is: said in line flue is provided with in line valve plate, flue before the in line valve plate is provided with another smokejack, waste heat radiator and air-introduced machine are housed behind the smokejack, the waste heat radiator is contained in the outlet of heating stove smokejack, after air-introduced machine is contained in radiator.Have air-introduced machine to help smoke evacuation, the waste heat radiator can be contained in lower position in order to heating.The size and the quantity that can radiator just be set according to the size and the flue-gas temperature of heating stove scale.

The utility model also can be provided with polishing filter, to reduce exhaust emission, concrete structure is: said air-introduced machine outlet feeds polishing filter through pipeline, and pipe outlet is positioned under the liquid level of polishing filter purification absorption liquid, blowoff valve is equipped with in the bottom of polishing filter, and flue is equipped with on top.The flue on barrel-shaped filter housing top is discharged the waste gas after purifying.Purification absorption liquids such as limewash are housed in the filter, introduce decontamination in the limewash by the flue gas that air-introduced machine is sent here by pipeline, most of sulfur oxide generates calcium sulfate through absorbing after and calcium sulfite precipitates, and gate valve is housed below the filter, opens gate valve and can discharge sediment by sewage draining exit.

The utility model has the advantages that thermal efficiency height, caloric value is big, and exhaust emission is little, waste heat fully can be recycled, owing to adopt the upper and lower furnace chamber of self-timing combustion system successively, has prolonged burning time, has reduced stoking number of times every day.

The utility model has following accompanying drawing:

The environment-friendly heating furnace structure schematic diagram that Fig. 1 is honeycomb briquette fired

The basket schematic diagram of coalingging of Fig. 2 heating stove

The dividing plate schematic diagram of Fig. 3 heating stove

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the utility model structural representation.The utility model main body comprises furnace chamber, delivery port 1, water return outlet 6, bell 8, last smokejack 12, down smoke-discharging road 13, flue conversion valve plate 9, last coal basket 2, following coal basket 4, central dividing plate 14 and the in line flue 11 of being with water jacket 7.Last smokejack 12, down smoke-discharging road 13 are connected with smokejack 15 and in line flue 11, and in line flue 11 is equipped with in line valve plate 10, and waste heat radiator 20 and air-introduced machine 19 are housed behind the smokejack 15; The outlet of air-introduced machine 19 feeds polishing filter 18 through pipeline, and the purification that pipe outlet is positioned at polishing filter absorbs under the liquid level, and blowoff gate valve 22 is equipped with in the bottom of polishing filter, and flue 17 is equipped with on top.Smooth and easy when lighting a fire for smoke evacuation, light soon, can open the in line valve plate 10 on the in line flue earlier, light the fire coal 5 in the lower furnace chamber, and shut with the outlet that flue conversion valve plate 9 will be gone up smokejack 12, cigarette is discharged by in line flue 11 through down smoke-discharging road 13.After firing, coal in the lower furnace chamber can close in line valve plate 10, start air-introduced machine 19, this moment, hot cigarette was sent to waste heat radiator 20, cold smoke after the heat radiation is sent into polishing filter through air-introduced machine, nuisances such as the sulfur oxide in the cold smoke are purified absorption liquid 21 by alkalescence and absorb, and flue gas after being purified enters atmosphere by flue 17.Can produce precipitation after purifying the absorption liquid use, can regularly open blowoff valve 22, sediment be discharged by sewage draining exit 23.Fire coal 5 in the lower furnace chamber changes the position of flue conversion valve plate 9 near after burning down, and with the port closing in down smoke-discharging road 13, go up the port opening of smokejack 12, ignites and goes up fire coal 3 in the furnace chamber, and the order of packets burning realizes getting on, get off.Air-introduced machine available horsepower 20～40W, the Small Centrifugal Fan of 2～3 grades of air quantity is arranged, to be fit to different needs.

Fig. 2 is the heating stove blue schematic diagram of coalingging.Coal-fired 3,5 for ease of changing, can be cylinder iron or heat resisting steel make gaily decorated basket shape, change when coal-fired and tick together with coal indigo plant 2,4.As a kind of specific embodiments, optional 8～10 millimeters of the blue railing diameter of coal, 4～5 on every side.

Fig. 3 is a heating stove dividing plate schematic diagram, can adopt the circular plate of cast iron, perforate on the plate, and as a kind of specific embodiments, about 5 millimeters of its thickness has the hole of 12 diameter 15 millimeter above.

Though more than present embodiment has been done detailed explanation, in the middle of concrete enforcement, can make certain flexible by present principles, can be used as waste heat radiator usefulness such as four common post radiators; Waste heat radiator and polishing filter are equally also applicable to being the heating stove of fuel with the coal that looses.
