Description

A kind of environmental-protection combustible powder clean gasifying apparatus
Technical field
The present invention relates to a kind of combustible powder be carried out the process unit of airtight pressurized gasification, particularly a kind of environmental-protection combustible powder clean gasifying apparatus.
Background technology
A large amount of at home at present gasification technologies that use are mainly normal pressure immovable bed gasification technology, the raw material that uses can only be coke or anthracite block coal, not only price is expensive, and the source channel of raw material is very restricted, generally can only use the anthracite block coal in Shanxi, gasification reaction temperature in this technology is lower simultaneously, gasification efficiency is very low, pollute heavy, make the output and the production cost of manufacturer all can not reach the ideal state, in the normal pressure immovable bed gasification technology, the gasification reaction temperature is about 800～1000 ℃, pressure in the burner hearth is a normal pressure, no spray gun, the ring-like pipe of hot wall, fast cooling device etc.
Meanwhile, domestic more existing units are developing new gasifying process, as the ash fusing fluidized bed gasification technology that pressurizes, four nozzle pressurized water coal slurry gasification technologies, but shortcoming is separately arranged all, and the industrialized unit that does not all also have success, though as the ash fusing fluidized bed gasification technology part of pressurizeing solved pollution problem, the gasification reaction temperature also has only about 800～1000 ℃, and efficient does not still reach the ideal level; And four nozzle pressurized water coal slurry gasification technologies adopt entrained flow bed gasification technology, with the coal water slurry is raw material, though technology advanced person, the gasification efficiency height, and it is pollution-free, but owing to be firebrick structure around the burner hearth, make the gasification reaction temperature still restricted, can only arrive about 1350 ℃, if make this technology reach the ideal effect, can only adopt the fat coal in several places, as Huating coal etc., not only price is higher, and output is limited, concerning the manufacturer of great majority application gasification technology, this technology can't realize.
Summary of the invention
Technology of the present invention is dealt with problems: overcomes above-mentioned weak point of the prior art, and a kind of gasification reaction temperature height, gasification efficiency height, pollution-free is provided, and environmental-protection combustible powder clean gasifying apparatus simple in structure.
Technical solution of the present invention is: a kind of environmental-protection combustible powder clean gasifying apparatus, comprise spray gun, body of heater, hot wall shape pipe, fast cooling device, knockout drum, special spray gun axially is installed in the top of body of heater, be provided with the ring-like pipe of hot wall around the body of heater, there is refractory materials the inboard of the ring-like pipe of hot wall, and the bottom of body of heater is connected with knockout drum by the fast cooling device.
Described extraordinary spray gun mainly by be used for oxygen delivery to the central oxygen tracheae of burner hearth, be used for combustible powder and rare gas element be transported to the ring-like pipe of combustible powder of burner hearth, the ring-like pipe of water vapor that is used for water vapor is transported to burner hearth is formed, central oxygen tracheae, the ring-like pipe of combustible powder, the ring-like pipe of water vapor are the telescoping structure that cylindrical tube adds conical tube, lump together by soldering group, and be installed on the top of body of heater.
Described fast cooling device mainly is made up of cooling cylinder, cooling medium transport pipe, and cooling medium transport pipe is a plurality of, and circumferential arrangement is around the cylinder of lowering the temperature, and by being installed on the bottom of body of heater.
Combustible powder is by handling, make the tiny powder of exsiccant, pass through the special spray gun that install at the body of heater top by combustible powder again with rare gas element (as N2, CO2 etc.) positive delivery, axially enter in the burner hearth, at high temperature carry out partial oxidation reaction with the oxygen of together carry, water vapor etc., generate synthetic gas.Among the present invention, the gasification reaction temperature range of burner hearth is 1400～1800 ℃, and pressure range is 1.5Mpa～10Mpa.The synthetic gas of this moment contains a large amount of ash, and the product that generates simultaneously after the reaction also has granular slag.The pyritous synthetic gas at first will intersegmentally connect cooling through one in the burner hearth of body of heater, cooling is to realize by the ring-like pipe radiation thermal conduction of hot wall around the intravital burner hearth of stove, intersegmental to connect refrigerative synthetic gas temperature still very high through one, synthetic gas and the slag of this moment will be through fast cooling devices in the bottom of burner hearth of the furnace body, forced conveyance than the much lower liquid of synthetic gas temperature or gas by the fast cooling device, with synthetic gas and slag thorough mixing, by direct heat exchange synthetic gas and slag are cooled off, if the heat-eliminating medium of forced conveyance is a liquid, as water etc., then also a part of ash separation in the synthetic gas can be come out, in knockout drum, be deposited in the cryogenic media, the slag treatment system that ash content after the sedimentation together enters the bottom together with slag by the slag outlet, and synthetic gas (temperature is about 800 ℃) then is transported to the dedusting and the washing system in downstream by syngas outlet in knockout drum.
Advantage of the present invention is in following several respects:
Since the work such as subsequent disposal of conveying, reaction and the synthetic gas of material all in closed pipeline or container, carry out, and the pollutant component in synthetic gas and the sewage all will be handled by known maturation process, behind the airtight pressurized gasification, pollutent can be collected, handle by maturation process, therefore, the present invention has free of contamination advantage;
2. gasification reaction temperature height is 1400～1800 ℃, even the very high combustible powder of ash fusion point also can be realized very high efficiency gasification by the present invention.So wide adaptability of raw material, basically combustiblematerialss such as coal Anywhere or rubbish all can be used as raw material of the present invention, concerning chemical fertilizer and chemical enterprise that will or use the coal head, can realize the localization of raw material easily by the present invention, the price of raw material per ton is reduced greatly, reduce production costs;
3. gasification reaction efficient height, the present invention is advanced powder entrained flow bed gasification technology, and user's coal consumption is reduced greatly, further reduces production costs;
4. technique device reliability height of the present invention, invest little, especially concerning the medium and small fertilizer enterprises of China, present limited fund, exigence undergoes technological transformation again, uses the present invention and can reach the effect that investment is little, efficient is high, reduce production costs and increase economic benefit, minimizing pollution, improve product technology content.
