Summary of the invention
The present invention provides a kind of middle Gas feeding vapourizing furnace that is provided with single or many inlet pipe, overcomes less, the furnace diameter problem of smaller of refuse treatment scale of conventional garbage vapourizing furnace.
For achieving the above object, the present invention takes following technical scheme:
Gas feeding refuse gasification boiler in the middle of a kind of; Comprise body of heater and stove pin; Said body of heater top is provided with garbage inlet and pyrolysis gas outlet, and the body of heater middle and lower part is provided with furnace wall inlet pipe and furnace wall air inlet port, and bottom of furnace body is provided with fire grate and bottom inflow pipe; Innovative point of the present invention is: be provided with at least one central air induction pipe in the said body of heater, said central air induction pipe gets into body of heater from furnace roof.
Be provided with the vapourizing furnace of furnace wall air inlet port for body of heater in the prior art, said central air induction Guan Weiduan is positioned at air inlet port top, furnace wall.
Can be provided with equally distributed double central air induction hole on the end tube wall of said central air induction pipe.
If the single inlet pipe of above-mentioned central air induction pipe then is positioned on the body of heater axis; According to the big or small needs of furnace diameter, above-mentioned central air induction pipe can also be many inlet pipe, is the center uniform distribution with the body of heater axis, can be single circle and arrange, and also can be several concentric rings and arrange.These two kinds of distribution modes along the body of heater axis have guaranteed can evenly be passed into the intravital various piece of vapourizing furnace stove from the air that central inlet pipe feeds.
Benefit of the present invention is that the central air induction pipe can select single inlet pipe or the many even bubbling airs of inlet pipe for use according to vapourizing furnace furnace diameter size needs; Guaranteed rubbish when pyrolytic gasification in the body of heater each several part rubbish can both obtain enough air; Thereby guaranteed the homogeneity of pyrolytic gasification temperature in the vapourizing furnace; Make rubbish in the stove can both be under the ideal temperature pyrolytic gasification and be unlikely the generation that causes phenomenons such as blowing out because of formation coking too high or too low for temperature or half-cooked; And then can design, produce the bigger refuse gasification boiler of diameter and be used for the bigger occasion of garbage treatment quantity; Improve the refuse treatment ability, guarantee the continuity and the high efficiency of vapourizing furnace treating refuse.
