Description

A kind of improved structure of environment-protection combustion stove

Technical field

The utility model is related to burner installation technical fields, and in particular to a kind of improved structure of environment-protection combustion stove.

Background technology

Handwarmer is the simplest a kind of in combustion furnace, and this handwarmer coal pokes fire and all manually comes with scarfing cinder It completes.Although this stove labor intensity is big, but its operation operation is easily mastered, but in small boiler（D≤2t/h）, by In periodical coal, lead to the cyclically-varying of the imbalance and combustion process of supply and demand, is easy to cause the reduction of stove economy（Combustion It is about 50-60% to burn efficiency）, people, which have been commonly seen on some combustion furnaces, emits billowing black smoke, this is because oxygen when fuel combustion Caused by not supplied reasonably, and the exhaust gas that unburnt fuel generates, serious pollution can be caused to air, It threatens to the health of people.Authorization Notice No. is that the Chinese utility model patent of CN205783080 discloses one kind Heat storage box on environment-protection combustion stove, including furnace body, environment protection pipeline and furnace body, the utility model preferably solve fuel and do not fill The problem of divided combustion, and be to be heated into the air in burner hearth using the heating device in environment protection pipeline, its temperature is improved, Keep burner hearth fuel combustion more abundant, but its there is also following two problems：1, the sky supplemented to liner by environment protection pipeline Gas toward the exhaust gas that air chamber overflows is carried out by same air admission hole with liner, causes the air draught supplemented to liner unstable Fixed, there are still the hidden danger of fuel burn incompletely；2, heating device and heat exchanger is separately provided in the utility model, to passing through ring Mixed gas in keeping the road air and air chamber that supplements to liner is heated so that apparatus structure complexity and improving is set Standby cost.

Utility model content

In order to solve the defect that the above-mentioned prior art is mentioned, the application provides a kind of improved structure of environment-protection combustion stove, makes It is more stable to obtain the air draught supplemented to liner, ensure that the abundant burning of fuel, while using the waste-gas heat of itself to mending The air filled is heated, and it is not necessary that heating device is separately provided, its technical solution is as follows：

A kind of improved structure of environment-protection combustion stove, including furnace body, admission line and heat storage box, the heat storage box are mounted on stove It is connected to the burner hearth in the furnace body above body and by outlet pipe, activated carbon filter layer is fixed in the outlet pipe, Outer courage and liner are equipped in the burner hearth, there are air chamber between the outer courage and liner, the air chamber by the top of liner every The air chamber that plate is separated into above two closed air chambers and liner is connected to outlet pipe, and the liner includes inner wall, outer Wall and thermal insulation layer between the inner walls and the outer are evenly distributed with through the inner wall, outer wall and thermal insulation layer on the liner Air admission hole, and the liner wherein contacted with the air chamber of side is equipped with inlet non return check valve in the air inlet position of its outer wall, institute It states and is communicated with a circulating line between the top of heat storage box and admission line, which is equipped with gas flow regulating valve.

Further, the burner hearth is rotary structure, and the upper end cavity bore is big, lower end cavity bore is small.It is outer courage, interior Courage is according to the structure design of burner hearth, and when fuel combustion, the heat accumulation effect of efficiency of combustion higher, top is more preferable, is conducive to heat accumulation The thermal-arrest of case.

Further, the liner and the outer courage coaxial arrangement.The liner and outer courage are rotary structure and same Axis is arranged, and stable structure is reliable.

Further, the bottom of the furnace body is equipped with slag-drip opening, and plug has been removably installed on the slag-drip opening.This sets Meter is convenient periodically to clear up the ashes of burner hearth fuel, ensures efficiency of combustion；When cleaning, lower end cap, cleaning are dismantled After refill upper plug head.

According to above-mentioned technical proposal, the utility model compared with prior art, has the following advantages：

1, by installing inlet non return check valve on the air admission hole on liner so that the air supplemented to liner can pass through, but Exhaust gas in liner cannot but be spilt into the air chamber of side, ensure that the airflow stability of the air of supplement, in addition outside Thermal insulation layer is set between wall and inner wall, it is ensured that the normal use environment of inlet non return check valve avoids being influenced and extending by high temperature Service life；

2, circulating line is set between heat storage box and admission line, using the exhaust gas in heat storage box itself to the sky of supplement Gas is heated, and it is not necessary that heating device is separately provided, saves installation cost, activated carbon mistake is in addition fixed in outlet pipe Filtering layer can spill into liner the solid particle adulterated in the exhaust gas of heat storage box and adsorb, and avoid the occurrence of and supplemented with to liner Air mixing after block inlet non return check valve the case where.
