Description
Technical field
The present invention relates to the biomass gasifying furnace of the rotatable ash discharge of a kind of fire bars, by the rotation of fire bars self, ashes can be discharged furnace chamber fast in gas-making process, be specifically related to the fire bars structure in this vapourizing furnace.
Background technology
Utilize the biological particles such as the agricultural crop straw pulverized at Pintsch process condition lower gasification, it is the New Green Energy source domain of energy-saving and environmental protection, the agricultural crop straw wherein used common are maize straw, Cotton Stalk etc., and this technology especially has wide prospect of the application in Rural areas.This gas producing technology is developed so far, the Reaktionsofen numerous types gone out designed by different manufacturers, but structure is all comparatively simple, only can realize the basic function of Pintsch process, in aerogenesis quality, the aspect levels such as aerogenesis quantity, gas-made technology are poor, the various insoluble defect of ubiquity, such as, need the phenomenons such as blowing out ash discharge, biomass combustion are abundant not, inflammable gas content is low, tar content is high in gas-making process.
Fire bars is important composition parts of Reaktionsofen, usually furnace chamber bottom is arranged on, many fire bars permutation and combination become grate, and fire bars is generally fixed installation in Reaktionsofen, when biomass fuel burns till ashes and reaches the enough loose degree of structure, ashes can naturally fall discharge furnace chamber between fire bars, so spacing between fire bars needs reasonable in design, if overmatter, be unfavorable for ash discharge, arrange and thinly be then unfavorable for holding biomass, cause and Lou expect, be difficult to sufficient combustion.
In biomass combustion process, the furnace chamber temperature of Reaktionsofen is higher, present about 1200 DEG C, when biomass after-flame, always can not form loose ashes, there will be slagging scorification phenomenon on the contrary under the high temperature conditions, can not naturally land at all, ash discharge needs manual intervention, as disclosed disintegrating slag block with crooked chisel.Because Reaktionsofen bottom in gas-making process needs sealing, prevent combustion-supporting gas from entering, and be hot environment in Reaktionsofen, so necessary blowing out ash discharge, thus reduce production efficiency, restarting Reaktionsofen point biomass-burning also can waste starting material.
A kind of Reaktionsofen being provided with double-deck grate is described in Chinese utility model patent " a kind of heat scission reaction stove " (patent No.: ZL201120127663.1), double-deck grate is levels mechanism, upper strata grate relative lower floor grate can adjust spacing in the horizontal direction, different degree of closing can be formed between the fire bars of levels grate, the grate that space is larger can be combined to form, also the less grate in space can be formed, expect that can hold biomass makes its sufficient combustion, again can ash discharge smoothly, but the grate of this structure still cannot solve ashes clogging problems, not obvious to the improvement of gas-made technology.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of biomass gasifying furnace facilitating ash discharge, being provided with in this vapourizing furnace can the fire bars of synchronous rotary, fire bars is provided with tip tooth, when fire bars rotates, tip tooth is engaged, can implement slagging scorification ashes effectively broken, make ashes discharge furnace chamber smoothly.
