Description
Technical field
The utility model belongs to the coal gasification apparatus technical field, is specifically related to a kind of ring cavity water wall coal slurry gasifier.
Background technology
The resource situation of Chinese energy has determined us to be unable to do without coal, but in the coal utilization process, because method is improper or technological not advanced, has produced the serious environmental pollution.Along with fast development of national economy, increasingly high to improving energy transformation efficiency and requirement on environmental protection, press for and develop clean coal technology, coal resources are carried out rationally and effectively utilization, improve whole energy transformation efficiency, reduce pollution to environment.Developing large-scale, high effect cleaning Coal Gasification Technology is to solve the task of top priority that Chinese energy is rationalized problem.Adopt advanced gasification technology to greatly develop Coal Chemical Industry and related industries, both can reduce the pollution to environment, also can enlarge the coal scope, raw material can be used the bituminous coal for replacing anthracite, has good social benefit and economic benefit, is the important method of dealing with problems.
Coal Gasification Technology is the main path that primary energy source is converted into clean secondhand energy, and its product is fuel gas (coal gas), synthetic gas, reducing gas, hydrogen, carbon monoxide.The coal gasification technology has obtained using widely in the production of combined cycle (IGCC) power generation assembly, synthetic ammonia and synthesizing methanol industry, producing acetic acid by carbonylation method and acid anhydrides industry, sponge iron, the fields such as preparation of pure carbon monoxide, and effective utilization of the various energy that produces of how will gasifying is the key that reduces device running cost.
Pressing gasization technology wherein; Generally use mould material or the higher material of refractory brick heat storage capacity to reduce heat passage; Guarantee that the vapourizing furnace case temperature is within normal safety range; In case but mould material or refractory brick are leaky in the production process in construction, will collaborate causes the vapourizing furnace wall temperature to raise, when serious even parking.
In nowadays reducing vapourizing furnace wall temperature technology, none production safety environmental protection still, the Technology that technology is succinct, simple to operate flexibly, cost of investment is few, working cost is low.
Summary of the invention
The purpose of the utility model provides a kind of ring cavity water wall coal slurry gasifier.
The utility model is realized through following technical scheme:
A kind of ring cavity water wall coal slurry gasifier comprises that top has import, and the bottom has the shell of outlet; Be provided with combustion chamber and shock chamber in the enclosure; Top, combustion chamber is the burner mouth, and the bottom, combustion chamber connects the shock chamber, is the water wall ring cavity between combustion chamber and shock chamber and the shell; The porose dividing plate of water wall ring cavity arranged outside at combustion chamber and shock chamber's connecting portion; The top of the outside housing of described water wall ring cavity offers the import of protection gas, water outlet respectively, and general headquarters offer syngas outlet, and the bottom offers water-in.
CO
2Gas gets into gasifier water-cooling wall ring cavity through the metering back, and effectively isolated high-temperature technology gas contacts with the direct of vapourizing furnace housing, and can regulate the size of shielding gas add-on through back operation difference.
The beneficial effect of the utility model is: protection vapourizing furnace case temperature to a certain extent can be with a part of CO within normal index
2Gas converts CO gas into; Also can use other gaseous medias such as nitrogen, water vapour; Can reduce the working cost of vapourizing furnace to a great extent, can guarantee that simultaneously the vapourizing furnace case temperature maintains one very in the constant scope, has guaranteed the safe operation of vapourizing furnace.
