Description
Technical field
The utility model relates to a kind of by-product carbon dioxide that utilizes coal is locked into to the coal adding system that row fills pressure release.
Background technology
In prior art, the coal lock that the coal adding system of various pressurization static bed vapourizing furnaces is all used periodical operation is off and on to coal in vapourizing furnace, coal lock needs under normal pressure and pressure, switch frequently, and coal locks that lower valve is opened frequent, step-down and the pressurising time is long, cause coal adding system long, the raising, charging continuity and the stability that have a strong impact on the vapourizing furnace load consuming time.
The current coal adding system of industrial applications, when gasifying furnace device normally moves, that usually with the cooled coal gas of vapourizing furnace downstream unit or circulation coal lock gas, as coal, locks fills the pressure release medium, also can adopt the nitrogen pressurising.Pressure release gas is retrieval system after washing, purifying, collection store or act as a fuel gas or compression, or recycle after compression.But, adopt the coal of coal gas pressurising to lock the gas complicated component, the explosive inflammable gases such as the hydrogen that contains high level, carbon monoxide, methane, the safe class of requirement is higher, contains a large amount of solid coal and dust granule in gas, and e-quipment and pipe is had to abrasiveness; Also contain close-burning tar class material in gas, easily cause the obstruction to e-quipment and pipe.Therefore cooled coal gas or circulation coal lock gas fill decompression technique and equipment work inclement condition, overhaul of the equipments is frequent, in order to improve serviceability, usually adopt the standby mode (for example the using and the reserved or a use two are standby) of gas booster compressor, but equipment sparing increase facility investment and maintenance cost, occupied ground, and can the effective gas of loss part.Also there are following defects in prior art:
Cooled coal gas fills decompression technique: because downstream cooled coal gas pressure is low than vapourizing furnace pressure, therefore the coal lock pressurising later stage needs the time longer, after pressurising, coal lock pressure, still lower than vapourizing furnace pressure, therefore still needs the equaler line of coal lock and vapourizing furnace and valve to carry out finally all pressing of coal lock and vapourizing furnace.Because all press coal gas dust content, and may collaborate by high temperature, so equaler line and valve working inclement condition, valve easily leaks, and easily causes airtight the inspection unsuccessfully of coal lock in the pressurization of coal lock and pressure leak process, causes normal running to be interrupted.Cooled coal gas after pressure release has following several approach that utilizes:
Approach one: the gas that acts as a fuel of the cooled coal gas after pressure release, need separately establish the normal pressure gas cabinet pressure release coal gas is stored; And the fuel gas gas blower need be set, the cooled coal gas gas that just can act as a fuel is used.Therefore equipment is many, and floor space is large.For example fixed bed lurgi gasifier dry ash gasification technology usually adopt cooled coal gas as coal lock fill the pressure release medium, present technique has been used nearly 30 years on certain synthetic ammonia installation at home.
Approach two: cooled coal gas enters the normal pressure gas cabinet after washing, after compressed machine compression, returns to process system.Because with coal dust and tar, easily e-quipment and pipe is caused abrasion and stops up in cooled coal gas, so the compressor operating inclement condition, how standbyly often need to open.Therefore with approach one, same floor space is large, and equipment is many, and investment is large.
Approach three: the direct torch emptying of cooled coal gas, cause the available gas loss, the waste available gas.
Circulation coal lock gas fills decompression technique, and pressure release coal gas enters the normal pressure gas cabinet after washing, and coal gas during pressurising in gas holder boosts through the compression of coal lock air compressor, and coal is locked into to capable pressurising.Because the coal lock band of gas has coal dust and tar, easily e-quipment and pipe etc. is caused abrasion and stops up, so the compressor operating inclement condition, repair rate is high, and maintenance cost is large, and gas booster compressor can adopt the how standby pattern of a use.For example BGL fixed bed slag gasification technology usually adopt circulation coal lock gas as the coal lock fill the pressure release medium, present technique has successfully been used more than 20 years abroad.
Nitrogen fills decompression technique: the nitrogen that adopts the nitrogen pipe network carries out the pressurising of coal lock, the emptying after washing of pressure release nitrogen.When coal is locked to the vapourizing furnace coal, pressurized nitrogen can enter vapourizing furnace with coal, and final nitrogen enters in raw gas.Nitrogen is the indifferent gas (except needing the occasion of nitrogen in ammonia synthesis reaction or synthetic gas) of most of building-up reactionss, therefore nitrogen is not suitable for the coal lock pressurization of most of building-up reactionss upstream gasification, for example coal preparing natural gas, coal methyl alcohol processed, the synthetic wet goods of coal system.Nitrogen fills pressure release also wastes nitrogen, easily causes the pressure surge of nitrogen pipe network during pressurising.
