Abstract
A technical proposal of providing ground fuel electric plant or chemical plant and fertilizer plant with fuel or raw material by using coal gas produced by coal based gasification plant of coal mine. The coal gas produced by coal based gasification plant of coal mine is sent through pipeline or well to ground fuel electric plant as fuel or to ground chemical plant and fertilizer plant as raw material, especially to power plant beside pit mouth or chemical plant and fertilizer plant beside pit mouth as fuel or raw material. A cooling wall composed of cooling water pipes is disposed around the pipeline and well or in the well for transmitting the coal gas produced by coal based gasification plant of coal mine; and the heated cooling water is sent to the ground fuel electric plant or exhaust-heat boiler.
Description
Affiliated technical field
The present invention relates to a kind of coal gas that adopts as the steam power station of fuel with as chemical industry, the chemical fertilizer factory of raw material, especially adopt the coal gas that coal gasification plant is produced under the coal mine, as the steam power station of fuel with as chemical industry, the chemical fertilizer factory of raw material.
Background technology
At present, the known thermal power generation station-service raw coal on ground of building in is as raw material, existence is transported to ground with a large amount of coals from the down-hole, with transport to the power plant on ground from well head, construction cost, haulage device and freight height, coal ash and barrow floor space are big, mine and to cause surface collapse, the raw coal deficiencies such as a large amount of industrial chemicals of waste, serious environment pollution of directly burning; Also have a lot of steam power station build in the colliery near coal-mine near, the raw coal that adopts the colliery extraction nearby is as fuel, be called near coal-mine power plant, the transportation range of raw coal on the ground has just shortened near coal-mine power plant, and existing problem and other are with coal basic identical as the steam power station of fuel; Produce coal gas on ground with gas generator,, exist and the essentially identical problem in steam power station as the raw material of chemical industry, chemical fertilizer factory.
Summary of the invention
Have now on ground with coal as the steam power station of fuel and the coal gas produced with gas generator on ground as chemical industry, the existing wretched insufficiency of chemical fertilizer factory's raw material in order to overcome, the present invention proposes a kind of coal gas of producing with coal gasification plant under the coal mine, for the steam power station on the ground provides fuel and is the chemical industry on ground, the technical scheme that chemical fertilizer factory supplies raw materials.
The technical solution adopted for the present invention to solve the technical problems is: for the steam power station, the coal gas that underground gasification factory produces is delivered to the steam power station as fuel with pipeline, can be earlier coal gas be extracted behind the industrial chemicals again as fuel; For chemical industry, chemical fertilizer factory, the coal gas that underground gasification factory produces is delivered to chemical industry, chemical fertilizer factory as raw material with pipeline, can utilize earlier behind the waste heat in the coal gas again as raw material; If steam power station or chemical industry, chemical fertilizer factory especially far are not easy to tubing, the available dedicated dirigible transports coal gas.
The invention has the beneficial effects as follows: can reduce or remit with a large amount of coals from the down-hole to ground and on the ground carriage height, coal ash field and spoil floor space big, mine cause surface collapse, the waste of burning raw coal is big and wretched insufficiency such as serious environment pollution, utilize prior art just can realize substantially, be particularly suitable for existing near coal-mine Power Plant Fuel is improved.

The specific embodiment
In Fig. 1, the coal gas that underground gasification factory produces is sent into the ground gas treatment plant through pipeline; After gas treatment plant desulfurization, dedusting and extracting industrial chemicals such as coal tar, phenol, ammonia, send into the steam power station, ground as fuel; Because of gas treatment plant need be produced raw materials such as coal tar, phenol, ammonia at low temperatures, need sending into gas treatment plant coal gas cooling before, at the cooling wall that heating gas pipeline arranged around cooling water pipe is formed, the cooling water after being heated enters electricity generation boiler.
In Fig. 2, the coal gas that underground gasification factory produces is sent into the ground gas treatment plant through pipeline; After gas treatment plant desulfurization, dedusting and extracting industrial chemicals such as coal tar, phenol, ammonia, send into ground chemical industry, chemical fertilizer factory as raw material; Because of gas treatment plant need be produced industrial chemicals such as coal tar, phenol, ammonia at low temperatures, need sending into gas treatment plant coal gas cooling before, at the cooling wall that heating gas pipeline arranged around cooling water pipe is formed, the cooling water after being heated enters waste heat boiler.
