Abstract
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.
Description
Technical field
The utility model relates to coal-fired gasification field, especially a kind of down-draft type gasifying furnace continuously.
Background technology
When existing vapourizing furnace air is produced air gas or produces semi-water gas with oxygen-rich air, adopt vaporized chemical to enter vapourizing furnace continuously from bottom, generate the mode of gas from Base top contact; With air, steam for vaporized chemical produce semi-water gas or water-gas time, all adopt batch operation method.Process pipe more complicated during employing periodical operation, and the output of coal gas adopts air inducing pattern, if coal gas output channel leaks, makes air enter in coal gas, there is detonation hidden danger.
Utility model content
The utility model proposes a kind of down-draft type gasifying furnace continuously, solving existing vapourizing furnace can not non-stop run, and there is the problem of detonation hidden danger.
The technical solution of the utility model is achieved in that
A kind of down-draft type gasifying furnace continuously, comprise burner hearth, continuous feeders and gas dust remover, described continuous feeders is arranged on described roof of the furnace, described gas dust remover is arranged on described lower furnace portion, described roof of the furnace comprises inlet mouth, described inlet mouth is connected with one end of vaporized chemical airduct, and the other end of described vaporized chemical airduct is connected with high pressure positive blower.
As preferably, described vaporized chemical airduct and high pressure positive blower junction are provided with valve.
As preferably, described continuous feeders top is provided with opening for feed, and described gas dust remover top is provided with coal gas air outlet.
As preferably, also comprise between described gas dust remover and burner hearth and store ash and go out ash-pan, described in store ash and go out ash-pan and driven by ash discharge disk drive device.
As preferably, described lower furnace portion is also provided with three supporting legs, and described supporting leg is evenly distributed on described lower furnace portion.
The utility model is by providing a kind of down-draft type gasifying furnace continuously, and its beneficial effect is:
1, vaporized chemical and gasified raw material are all advanced downwards from top of gasification furnace, and adopt blower fan forced-air blast, improve gasification intensity, impel the cracking such as the tar in coal gas volatile matter, reduce the tar content in coal gas, solve coal gas output channel under air inducing pattern to leak simultaneously, make air enter in coal gas, there is the problem of detonation hidden danger;
2, the interpolation of gasified raw material and the excretion of waste residue all do not affect the continous-stable output of coal gas.
