Abstract
The utility model discloses a gasification furnace, in particular to an energy saving and environment friendly straw gasification furnace. The straw gasification furnace comprises a furnace body, a furnace cover and a furnace hearth, wherein the furnace hearth is respectively connected with an air supply outlet opening at the bottom part and an air outlet opening at the upper part, and the air supply outlet opening is connected with an air inlet opening. The utility model is characterized in that air holes positioned in the furnace hearth are arranged on the upper side walls of the pipelines of the air supply outlet opening and the air inlet opening; a material dropping device positioned in the furnace hearth is installed at the top part inside the furnace body. The material dropping device is a cone body with a bottom part upward. The utility model can perform gasification to all flammable plant biomass raw material through oxygen-controlled combustion to generate combustible gas to provide for daily water boiling, cooking, warming and taking a shower, is a clean, hygienic, environment friendly and energy saving furnace, and is taken as a substitutable product for a coal-fired furnace, a gas stove and a traditional firewood stove.
Description
(1) technical field
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 rise again (oneself breaks through 100 yuan every bottle some areas) of rising 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.
(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 stalk gasifier are provided.
The utility model is achieved by the following technical solution:
A kind of stalk gasifier, comprise body of heater, bell, burner hearth, described burner hearth connects the air outlet of bottom, the gas outlet on top, and air outlet is connected with air inlet, and its special character is: described air outlet and air inlet pipeline upper side wall have the wind hole that is positioned at burner hearth.
Stalk gasifier of the present utility model, described body of heater inner top is equipped with the feeder that is positioned at burner hearth.Described feeder is bottom-up cone.Owing in body of heater, increased the feeder of cone shape, reach the automatic whereabouts of stalk, reach the effect that enclosure space reduces oxygen simultaneously.
The utility model can gasify all flammable plant biological raw materials (comprising agricultural crop straw, sawdust, wood shavings, various cereal, beans, peanut shell, bacterium slag discarded object 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.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1 gas outlet, 2 feeders, 3 air outlets, 4 tanks, 5 air inlets, 6 bells, 7 bodies of heater.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises body of heater 7, bell 6, burner hearth, the outer wall of body of heater 7 is equipped with tank 4, burner hearth connects the air outlet 3 of bottom, the gas outlet 1 on top, and air outlet 3 is connected with air inlet 5, and air outlet 3 and air inlet 5 pipeline upper side walls have the wind hole that is positioned at burner hearth.Body of heater 7 inner tops are equipped with the feeder 2 that is positioned at burner hearth, feeder 2 be shaped as bottom-up cone.The utility model is little at stalk density, and is mobile poor, and characteristics such as easily build bridge, find time have increased the feeder of cone shape, and the uniform and stable reaction of realization gasification furnace alleviates operative employee's labour intensity.The utility model has adopted bottom of furnace body to blow towards periphery, having top, middle part pipeline to form secondary again blows towards periphery, form twice air supply mode and make gas dry distillation charring and hot blast oxidation and thermal chemical reaction, straw in the body of heater is decomposed fully, living beings are arranged under the condition of airtight burn incompletely, form a kind of mixed combustible gas body.
Claims (3)
1. stalk gasifier, comprise body of heater (7), bell (6), burner hearth, described burner hearth connects the air outlet (3) of bottom, the gas outlet (1) on top, air outlet (3) is connected with air inlet (5), it is characterized in that: described air outlet (3) and air inlet (5) pipeline upper side wall have the wind hole that is positioned at burner hearth.
2. stalk gasifier according to claim 1 is characterized in that: described body of heater (7) inner top is equipped with the feeder (2) that is positioned at burner hearth.
