At present, gasification oven just is being subjected to people with himself characteristics more and more to be favored, but the following problem of gasification oven ubiquity commonly used now: 1. unreasonable structure, and the combustible gas that gasification produces is less, can't satisfy lasting, normal burning; 2. the tar content that produces gas is higher, stop up the burner and the pipeline thereof of gas-cooker easily, and cleaning strength is big; 3. the pernicious gas that produces of gasification can not get purifying as containing sulfide etc., and environmental pollution is more serious.
The utility model content
Technical problem to be solved in the utility model provides the improved gasification oven that a kind of gasification rate is fast, tar content is few.
For solving the problems of the technologies described above, the technical solution of the utility model is: improved gasification oven, comprise vaporizer, the gas-cooker that is communicated with described vaporizer, be provided with the combustion gas filter between described vaporizer and the described gas-cooker, be provided with material pressing device in the described vaporizer, be opened on described vaporizer bottom, be used in vaporizer, providing the blower fan of air.
As a kind of improvement, described material pressing device is made of spiral propeller;
As further improvement, described vaporizer bottom, be used for providing the steam jet of steam to described vaporizer;
As further improvement, described combustion gas filter comprises first Rose Box that is installed on described vaporizer outlet side and second Rose Box that is installed on described gas-cooker end;
As further improvement, described first Rose Box comprises casing, seals the sealing case lid of described first casing, is provided with annular clamp in described first casing, be provided with the charging basket of some air-vents bottom being placed with on the described annular clamp, fill the solid filtering thing in the described charging basket;
As further improvement, described solid filtering thing is made of crushing straw;
As further improvement, described second Rose Box comprises casing, is arranged on the escape pipe at the described second casing top, filling liquid filtering agent in described second casing;
As further improvement, described liquid filtering agent is a water.
Owing to adopted technique scheme, improved gasification oven, comprise vaporizer, the gas-cooker that is communicated with described vaporizer, be provided with the combustion gas filter between described vaporizer and the described gas-cooker, be provided with material pressing device in the described vaporizer, be opened on described vaporizer bottom, be used in vaporizer, providing the blower fan of air, on the one hand, by material pressing device compacting stalk, thereby the limit oxygen that helps stalk burns, on the other hand, can the more stalk of splendid attire in the vaporizer, produce more fuel gas.Blower fan will be blown into vaporizer from bottom to top as the air of gasifying agent, guarantee carrying out smoothly of gasification reaction.After the combustion gas that generates is installed filtration after filtration, remove harmful substance such as tar, sulfide in the combustion gas, protected environment.And the fairly simple compactness of described vaporizer overall structure, also reduced cost, be convenient to popularize.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
As shown in drawings, improved gasification oven comprises vaporizer 1, a cylindrical shape hollow barrel of the stalk that is used for gasifying, and the part of its underpart is convenient to compressed straw to centroclinal, the gasification stalk, Qi Hua combustion gas simultaneously is discharge easily also; With the gas-cooker 2 that described vaporizer 1 is communicated with, the fuel gas that described gas-cooker 2 is used for burning and produces in the described vaporizer 1 is about to fuel gas and changes into heat energy by burning, is used for carrying out the conversion of energy; Be provided with the combustion gas filter between described vaporizer 1 and the described gas-cooker 2, described vaporizer 1 comprises the charging aperture 11 that is arranged on the described vaporizer 1, be arranged on the slag notch 12 of described vaporizer bottom, be arranged on the exhaust outlet 13 on described vaporizer 1 top, be arranged on the exhaust outlet 13 on described vaporizer 1 top, described exhaust outlet 13 is discharged the gas that described vaporizer 1 produces; After agricultural crop straw is pulverized, enter in the described vaporizer, after gasification is finished, the stalk bits are discharged from the slag notch 12 that is arranged on described vaporizer bottom from described charging aperture 11.
Be provided with material pressing device in the described vaporizer 1, described material pressing device is made of spiral propeller 5, the effect of described spiral propeller 5 is that the agricultural crop straw in the described vaporizer 1 is compressed, make stalk be relatively easy to limit the oxygen burning, and make the crushing straw change of splendid attire in the described vaporizer 1 many, make the combustion gas of generation can form lasting burning.Described vaporizer 1 bottom is provided with blower fan 6, after stalk is compacted, tend to cause the stalk of vaporizer 1 bottom can't gasify because of can not get gasifying agent, the effect of described blower fan 6 is exactly will feed vaporizer 1 as the air of gasifying agent from bottom to up, accelerates the gasification rate and the efficient of stalk.
