Description

High-efficient coal-saving multipurpose stove

A kind of high-efficient coal-saving multipurpose furnace is used for solid fuel warming stove or drinking water drinking water boiler.

At present the vertical heater or the drinking water boiler of the civilian heating of China are varied, but generally all be straight flue, a large amount of heats runs away along flue.Their burning area is big, and heating surface area is little, and the stove that has is in order to strengthen heating surface area, stove is increased, caused the stove moulding asymmetric, the thermal efficiency is low, waste fuel, heat supply is slow, CN89204687.2 inverted flue multi-function gas producer, has inverted flue, increase heating surface, form flue gas reburning and burn, improved the thermal efficiency, but this stove only is applicable to family's kitchen range stove, is not suitable for drinking water boiler or than large tracts of land heating stove.

The purpose of this utility model provides a kind of fume-returning, heating furnace that thermal efficiency height is economized on coal and drinking water boiler.

The technical solution of the utility model realizes by following content, it comprises burner hearth, hydroecium, fuel port, slag notch, flue, outlet pipe, return pipe, it is characterized in that the body of heater that hydroecium is made of two water-filled interior hydroeciums 24 of vertical rings and outer water chamber 11, the space of two hydroeciums constitutes the fume-returning road 12 of walking cigarette, annular smoke-box 2 under the interior hydroecium 24 of flue and furnace bottom communicates, its underpart has the hydroecium tube connector and connects two hydroeciums between two hydroeciums, its upper top has the tube connector 13 of interior outer water chamber, make the water in the pipeline enter interior hydroecium 24 by return pipe 22, connecting tube 13 through top enters outer water chamber 11 again, be filled among two hydroeciums, be provided with outlet pipe 14 in the middle of on stove, make the hot water in the hydroecium, in the pipeline of input heating.Many water pipes that have at least three rows on the top of burner hearth are heating tube 17, be welded on the inwall of interior hydroecium 24, the water of water pipe 17 and the water of interior hydroecium 24 are led to, the fuel combustion of burner hearth like this, heating three rows' many water pipes 17, make hydro-thermal fast of hydroecium, also fast to the networking heat supply, these heating tubes all are with incline direction and interior hydroecium wallboard seal welding, the aqueous vapor of pipe is risen, enter hydroecium.On stove, be provided with ventilation duct 15, it is a double-walled by outer water chamber 11, Han Jie tubulose passage 15 mutually, communicate with the inverted flue of two hydroeciums, passage 15 has the cover plate 25 that can regulate atm number, make the oxygen of regulating at any time in the additional flue of air quantity, the fuel gas that helps in the flue burns, simultaneously also can be from the combustion case in the ventilation duct 25 observation flues.

Middle part at the interior hydroecium 24 of stove, be welded with 2～3 by interior hydroecium double-walled, and the tubulose ignitron 18 of sealing leads to fume-returning road 12, fire combustion in the burner hearth can be gone here and there out enter flue 12, can burn once more in flue, the atmosphere that ventilating opening is come in can be combustion-supporting, to increase heat, make sufficient combustion reach purpose of energy saving, the dirt that also reduces simultaneously on the flue inwall is long-pending.In the ring smoke chamber 2 of furnace bottom, has outlet flue 3, for making flue gas at the smoke chamber uniform balance.In smoke chamber, be provided with crescent flow distribution plate 4.Just do not make flue gas directly go out outlet flue 3, be provided with the deduster 26 that can rotate in interior hydroecium 24 bottoms, deduster has four rubbing board bars, scatter and stretch to flue 12, when the needs dedusting, use an instrument, make deduster 26 left-right rotation, stretch to the rubbing board of 12 li of flues, can remove the laying dust on the walling of flue, to guarantee the thermal efficiency of stove.

The utility model has compared with prior art that volume is little, ratio matches, the about 40:1 of heating surface area since upper furnace be provided with at least three rows a plurality of heating tubes, make heat supply fast.Establish the [that communicates with atmosphere has and covers 25 as the secondary oxygen supply on the top of stove, port lid 25 can adjustment hole size, the flow of air, improved the flammability of burner hearth like this, solve fuel oxygen supply deficiency when burning, solved the aphlogistic problem of a part of combustion gas, can be observed the combustion position of smoke returning flue again, also can clear up the dust stratification of air-returen flue, this stove (100-600mm that can warm oneself ²) can reach more than 50% by the checking coal saving rate, reduce atmosphere pollution, can provide hot water again, can also make drinking water boiler the boiling water of drinking is provided.

Accompanying drawing is a structural representation of the present utility model.

1. stove leg, 2. smoke chamber, 3. venthole, 4. flow distribution plate, 5. in the hydroecium Outer Bottom Plating, 6. interior hydroecium inner panel, 7. slag notch, 8. coal filling hole, 9. outer water chamber's outer wall, 10. outer water chamber's inwall, 11. outer water chamber, 12. inverted flues, connecting leg on 13. hydroeciums, 14. outlet pipes, 15. breather pipe, 16. interior hydroecium loam cakes, 17. heating tubes, 18. fire-outtaking tubes, 19. hearth wall, 20. interior hydroecium outside plates, 21. fire bars, connecting leg under 22. hydroeciums, 23. return pipe, 24. interior hydroeciums, 25. transfer wind cover plates, 26. dedusters

Make the specific descriptions of embodiment below in conjunction with accompanying drawing:

The utility model is pressed shown in the accompanying drawing, and its main material steel plate after the roll bending drawing, cooperates steel pipe again, and the round steel welding forms.The inwall 19 of interior hydroecium 24 is little on the shape in the burner hearth is, big down, coal filling hole is located at the middle part of stove, the bottom is for removing cinder notch 7, the smoke chamber 2 of the bottom of stove is the place that annular is walked cigarette and smoldered as shown in drawings, the centre is provided with outlet flue 3, flow distribution plate 4, can be made into meniscate, be located on the outlet flue towards the smoke chamber the inside, the flue gas of smoke returning flue is shunted, made the flue gas in the air chamber even, be unlikely the concentrated outlet flue that pours, the middle place that goes to the bottom of hydroecium 24 exterior panels in deduster is contained in, have four rubbing boards, make extending of symmetry, stretch in the flue to the bent around of stove to the four directions with laths of metal, a wherein rubbing board bar that hooks deduster 26 with a hook during use makes its rotation, because the mouth of hydroecium tube connector and coal and stopping of slag discharge hole structure are arranged in the flue, can not make the rotation of deduster circumference, also needn't rotate by circumference, get final product to commentaries on classics in the other direction when running into obstacle, the dirt that can draw together in the flue is long-pending again.The following supporting leg 1 of stove is being supported whole body of heater, be full of water in interior outer water chamber and the water pipe after, the fuel combustion of burner hearth is heated simultaneously, heating tube, the CO of its flue gas and CO ₂Rise and to enter flue and return, enter smoke chamber downwards along the flue between the interior outer water chamber and enter chimney by outlet flue by flow distribution plate.Can establish air-introduced machine for making cigarette walk the outlet flue place smoothly, increase draft, the whole caps of cigarette are gone out.
