Oily settler 76 has the thick Gas Pipe 77 for being connected to biomass burner 3 and the 3rd time burnt pipe for being connected to the connecting tube 68
78。
The top of gasification furnace 1 is provided with exhaust stack, and the exhaust stack is provided with the second axial flow blower 79, the second axial flow blower
79 take out burnt pipeline 70 by second is connected to detarring precipitator 76.
Elevator 71 and the top of top feed bin 72 set the first axial flow blower 74 to aspirate equipment for gasification and played a reversed role combustion gas and dust,
Reduce elevator 71 and the inside smoke tar of top feed bin 72 and dust concentration, avoid elevator 71 and top feed bin 72 occur it is quick-fried
Combustion.Furnace roof exhaust stack top set the second axial flow blower 79 aspirate the combustion gas arranged outside equipment for gasification Initial Stage after Ignition or blowing out initial stage and
Tar, outer be discharged in air is avoided to cause environmental pollution.
The gas tar oil of above-mentioned suction takes out burnt pipeline 75 and second by first and takes out the burnt feeding of pipeline 70 inertia
Detarring precipitator carries out combustion gas and the first separation of tar, and biomass combustion is sent into the thick combustion gas after the separation of inertia detarring precipitator
To biomass boiler hearth combustion, the tar after the separation of inertia detarring precipitator is finally sent through the 3rd time burnt pipe 78 for the import of device
Enter and collected in tar collection box collection 69.
In conventional art, in biomass gasification system forklift feeding process, feeding bin traditional approach is open design, largely
Tiny micro mist be diffused into neighbouring region, cause the deterioration of working environment, have a strong impact on the health of operative employee.Meanwhile
Feeding bin inner space belongs to normal pressure, and the concentration of dust causes local malleation in the case of gradually increasing so that dust is largely outer
Ease.Moreover, during biomass belt filled, there is the entrainment of tiny micro mist in bottom feed bucket in raw material upset course of conveying
And diffusive transport, pollute working environment.
