Description
Technical field
The present invention relates to a kind of coal gas production method and equipment, relate in particular to the method that a kind of coal gasification is produced coal gas, and adopt this method to produce the equipment of coal gas.
Background technology
Than burning of coal, the burning of coal gas more cleans, efficiently, so coal gas is just receiving more and more widely concern as a kind of clean energy.The Coal Gasification Technology that coal is converted to coal gas is looked gas-solid state and mode of motion in the stove, mainly can be divided into three major types: (particle diameter 10～50mm) is the fixed bed of raw material with lump coal; With fine coal (particle diameter is less than 10mm) is the fluidized-bed of raw material; With fine coal (particle diameter is less than 0.1mm) is the air flow bed of raw material.In the production process of reality, the gasification of fine coal is higher than the lump coal gasification efficiency, is the main gasification means of research at present and application.
The gasification principle that utilizes fine coal to produce coal gas is the reaction of coal and vaporized chemical, is the reaction of carbon, oxygen and water in essence.In common producer gas generator, with coal, and vaporized chemicals such as water vapor, air feed in the producer gas generator, and then coal and vaporized chemical react, and main reaction formula comprises the combustion reactions of carbon and oxygen, emits a large amount of heat energy, shown in (1):
C+O
2→CO
2+Q (1)
Wherein, heat is emitted in "+Q " representative.
Comprise that also carbonic acid gas and water vapor are the reaction of carbon monoxide and hydrogen by carbon reduction, the principal reaction formula is as shown in the formula shown in (2), (3) and (4):
CO
2+C→2CO-Q (2)
H
2O+C→H
2+CO-Q (3)
2H
2O+C→CO
2+2H
2-Q (4)
Wherein, " Q " representative absorbs heat.
The product carbon monoxide is the major ingredient of coal gas, and from above-mentioned reaction formula as can be seen, coal, oxygen and water vapor are the raw materials of producing coal gas, and carbonic acid gas is a kind of intermediate product, is again the direct material that generates coal gas.
Prior art can be circulating fluidized bed based on the employed producer gas generator of above-mentioned principle producing coal in next life gas, and its general structure comprises as shown in Figure 1: by the producer gas generator 100 and the whirlwind separator 200 of pipe connection.Wherein, be provided with fine coal inlet 110 in the middle and lower part of producer gas generator 100 sidewalls, can claim coal inlet again; Be provided with first inlet mouth 120 in its underpart, the air inlet first time that is fed mainly is an air, can claim air inlet again; Be provided with second inlet mouth 130 at the middle part of its sidewall, the air inlet second time of feeding mainly is a water vapor, claims the water vapor import again.Producer gas generator 100 is connected with the upper end of whirlwind separator 200, is used to transmit the gas mixture that is being mingled with solid particulate; The top of whirlwind separator 200 is provided with the derivation pipeline, the gas mixture of separating is derived, its lower end is drawn mouthfuls 150 and links to each other with producer gas generator 100 by being arranged on returning of producer gas generator 100 middle parts, be used to guide unreacted solid particulate, mainly be fine coal, be circulated back to burning once more in the producer gas generator 100.
The technology that this producer gas generator carries out gasification generally includes following process: fine coal, water vapor and air are fed producer gas generator, said mixture is reacted under the condition of high temperature, produce gas mixture, comprising carbon monoxide in this gas mixture, also comprise the gas of a certain amount of carbonic acid gas, water vapor, nitrogen and other a small amount of gas kinds, and be mingled with unreacted fine coal; After this gas mixture entered whirlwind separator, the fine coal deposition was then drawn back producer gas generator, and gas mixture is derived pipeline from the upper end is simultaneously derived, and the gas of derivation can obtain flammable industrial gas mixture again and send into user's use after purifying postprocessing working procedures.
Above-mentioned technology is a tradition coal gasification method commonly used, but wherein the subject matter of Cun Zaiing is: on the one hand, the reduction reaction efficient of carbon and water vapor, carbonic acid gas is low, causing unreacted fine coal and carbonic acid gas to be entrained in the gas mixture discharges, both reduced gas reforming efficient, also increased burden to postprocessing working procedures; On the other hand, contain great amount of carbon dioxide in the gas mixture of derivation, reduced the quality of gas mixture.
