Continuous downdraft gasifier

The utility model discloses a continuous downdraft gasifier belongs to coal -fired gasification field, including furnace (1), continuous feeding ware (2) and coal gas dust remover (3) furnace (1) top sets up an air inlet (4), air inlet (4) are connected with the one end of gasification agent tuber pipe (5), the other end and the high pressure positive blower (6) of gasification agent tuber pipe (5) are connected, make gasification agent and gasification raw materials all advance from the gasifier top downwards. The utility model discloses a fan forced -air blast, the gasification agent is all advanced downwards from the gasifier top with the gasification raw materials, improves gasification intensity, impels the schizolysis such as tar in the coal gas volatility, reduces the tar content in the coal gas, solves simultaneously that coal gas output pipeline leaks under the induced air mode, in messenger's air admission coal gas, has the problem of detonation hidden danger to the interpolation of gasification raw materials and the drainage of waste residue all do not influence the continuous firm output of coal gas, provide the work efficiency of gasifier.
