Description
(1) technical field under
The utility model relates to a kind of gasification furnace, specifically is a kind of stalk gasifier of energy-conserving and environment-protective.
(2) background technology
China's stalk resource is abundant, and two seasons of autumn in summer, a large amount of crop straw burnings caused atmosphere pollution, brings harm for the traffic safety and the people's life, becomes governments at all levels and various circles of society's question of common concern.Because natural energy resources is in short supply day by day, oil, natural gas, coal are in an emergency again and again simultaneously.Particularly domestic fuel price one such as liquefied gas rises and rises again (some areas have been broken through 100 yuan every bottle), has a strong impact on the people's life, and it is extremely urgent to seek substitute products.
There is the direct always for thousands of years burning straw of peasant more than 800,000,000 in China, and smoke fire burns, and they thirst for using convenient, fast, the clean gas of energy-conserving and environment-protective, comprehensive improving the quality of living; Simultaneously abundant agricultural straw resource etc. is fully utilized, form industrial chain, becoming the agricultural economy new growth point also is an important content of " building a New Socialist Countryside ", and hundreds of millions peasants long for.
In recent years, both ask in order to solve crop straw burning and to improve the rural energy structure, various biomass gasifying furnaces occur or be stalk gasifier, general gasification furnace in the market all is the oxygen supply of bottom nozzle formula, the oxygen supply of stone or metal plate for standing a stove on as a precaution against fire macropore or annular air intake, these several oxygen supply mode ubiquity firepower are weak, combustion gas quality is poor, combustion instability, aqueous vapor are obscured, easily flame-out, tar is many, igniting is difficult, causes gasification furnace to use quite complexity; Filter also is the critical component of gasification furnace simultaneously, whether the filtration device structure design rationally also is a key factor that influences the combustion gas height, and present filter mostly is to adopt drum type brake, and structure is too simple, do not have filter effect at all, cause tar content height, combustion gas quality low.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, and a kind of easy and simple to handle, excellent performance, broad-spectrum energy saving and environment friendly stalk gasifier are provided.
The utility model is achieved by the following technical solution:
A kind of stalk gasifier, comprise body of heater shell, burner hearth, shoot door, chimney, described burner hearth connects air inlet, gas outlet, air inlet is connected with blower fan, the gas outlet is connected with burner by wireway, its special character is: described wireway is provided with a condensate filter that has three filter chambers, and the air inlet place is the eddy current air supply device, and eddy current air supply device top is the wind hole that is positioned at burner hearth.
Stalk gasifier of the present utility model is provided with condensation chamber in the described condensate filter, is filled with condensation blocky-shaped particle material in the condensation chamber.
Be communicated with secondary air feed pipe between described blower fan and the burner.
Stalk gasifier of the present utility model, described body of heater cover top portion are equipped with the compressing rod that leads in the burner hearth.
Characteristics of the present utility model:
(1), the applicant is by the mechanism of tar generation in the research biomass gasification process, and the influence that temperature, firing rate, raw material variety, shape etc. produce tar in the stove, by optimizing furnace type structure, adding internals, realization is to the control of each reaction zone of gasification furnace, make it to be in the peak optimization reaction state, suppress the generation of tar or, produce the lower combustion gas of tar content, alleviate the burden of combustion gas post processing coke tar cracking.
(2), little at stalk density, mobile poor, characteristics such as easily build bridge, find time, the frame for movement that research is suitable, realize the uniform and stable reaction of gasification furnace, alleviate operative employee's labour intensity, and, realize the automatic control of gasification by to combustion gas composition, temperature, the isoparametric monitoring of bed depth.
(3), researched and developed the gas cleaning device that adapts with it, make that impurity such as tar is reduced in the standard of national related city coal gas in the combustion gas.Realize the real update of gasifying stalk stove and accessory.
Technical-economic index of the present utility model:
Gasification efficiency 〉=75%;
Fuel gases calorific value 〉=5MJ/Nm
5
Purify tar and dust content≤10mg/Nm in the combustion gas of back
5
The utility model adopts eddy current type circulation oxygen supply mode, makes oxygen-supplying amount balance more rationally, and aerogenesis speed is accelerated greatly, and firepower is strong, combustion gas quality is high, no longer exist flame-out phenomenon, tar output also to significantly reduce in the combustion process; Adopt special filtration means, increased by two filter chambers and inserted condensation blocky-shaped particle material simultaneously, make tar, steam basic filtering clean, combustion gas is pure.
The utility model can gasify all flammable plant biological raw materials (comprising agricultural crop straw, sawdust, wood shavings, various cereal, beans, peanut shell, edible fungi residues etc.) by the burning of control oxygen, in 2-3 minute, can produce imflammable gas, for dailyly heat up water, cook, the usefulness of heating, shower.Be really clean, sanitary, environmental protection, energy-conservation stove and accessory, be the substitute products of coal stove, gas kitchen ranges and traditional bavin kitchen range.
