Description
Technical field
The present invention relates to technical field of waste treatment, refers in particular to a kind of uniflow gas stove distribution ash exhauster.
Background technology
The research of biomass gasification technology deepens continuously, and it is very wide in the application prospect of environmental protection and new energy field.
Gasification of biomass be under certain thermodynamic condition, by composition biomass Hydrocarbon be converted into containing CO,
H2、CH4Deng the process of fuel gas.In order to provide the thermodynamic condition of reaction, gasification needs to supply air or oxygen, makes
Raw material generating unit divided combustion.The difference of gasification and common combustion process is the oxygen that abundance is supplied in combustion process, is made
Raw material fully burns, it is therefore an objective to which direct access heat, the product after burning is CO2The flue gas that can not be burnt again with vapor etc.；
Gasification only supplies the part oxygen needed for thermal chemical reaction, and energy is retained as far as possible obtain after the reaction flammable
In gas, the product after gasification is containing CO, H2、CH4With the fuel gas of low molecular hydrocarbon.
For top-suction type biomass gasification furnace, from top to bottom material can simply be divided into drying layer, pyrolytic layer, reduction
Layer and oxide layer.The temperature of wherein oxide layer is about 1100～1500 DEG C, and so high temperature, material can be tied in oxidizing process
Slag, therefore distribution, break, the ash exhauster of scientific design gasification furnace, the application to gasification furnace is particularly significant.
One air inlet pipe is arranged at traditional uniflow gas stove bottom, air inlet pipe stretches into gasification furnace bottom centre, with one upwards
Valve, distribution when air inlet pipe+valve gasifies as material is used.An ash-hole is opened in gasification furnace bottom sides, by row
Grey hole carries out break and ash discharge.This traditional design was once popular at 2009 or so, was nearly all uniflow gas stove
Standard design.This side ash-hole design break inconvenience, ash discharge is not thorough.Most importantly ash-hole and valve opposite side
Clinker be difficult to crush, lime-ash arrange not out.Once someone increased an ash-hole in opposite side, and ash discharge effect is necessarily changed
Enter, but the convenience or poor for operating.
