Description
Technical field
The utility model relates to a kind of gasification chilling train.
Background technology
At present, Shell Coal Gasification is one of comparatively advanced in the world Clean Coal Gasification Technology, have raw material availability high, consume low, to resources conservation, the remarkable advantage such as environmentally friendly.Shell Coal Gasification process is carried out under high temperature, pressurized conditions.Coal dust, oxygen and a small amount of steam under an increased pressure and flow in vapourizing furnace, complete series of physical and the chemical processes such as intensification, devolatilization, cracking, burning and conversion within the very of short duration time.Because gasification in-furnace temperature is very high, under aerobic conditions, there is combustion reactions in carbon, volatile matter and partial reaction product (H2 and CO etc.), there are the various conversion reactions of carbon after oxygen depletion totally, in the i.e. gasification reaction stage, final formation leaves vapourizing furnace with the coal gas that CO and H2 is main component.The crude synthesis gas leaving vapourizing furnace is through ash disposal and wash, a part enters follow-up methyl alcohol workshop section, Quench gas is served as in part backflow, because need Quench gas to carry out Quench coal gas of high temperature in the outlet of vapourizing furnace reaction chamber, the safe and stable operation of chill air compressor part directly affects gasification total system.
And there is complicated pipeline valve in the original design middle chill air compressor part of Shell Coal Gasification, from the crude synthesis gas of ash disposal system through pneumatic adjusting valve 13TV0020 and vacuum breaker, with from washing the crude synthesis gas of system through pneumatic adjusting valve 13PV0076 and vacuum breaker, the Y-tube congruence close after enter knockout drum.After through the pneumatic on-off valve 13XV0035 of chill air compressor import, enter chill air compressor pressurization, through the pneumatic on-off valve 13XV0036 of chill air compressor outlet after pressurization, there are 13PSV0011 and 13P,SV0,012 two safety valve respectively in import and outlet line.Rear portion Quench gas through variable valve 13FV0011 and vacuum breaker backflow of surge pipeline; A part is through 13FV0008 controlled chilling airshed and enter vapourizing furnace and carry out Quench after preventing synthetic gas from flowing backwards.
Pipeline valve complicated in macrocyclic operation can cause pipeline corrosion leak and failsafe valve by larger probability, each tie point is potential safety hazard point, because long-time under high temperature and high pressure environment, also the risk of gas leakage can be there is in the interface that stopping property is good again, and the gas in this device is inflammable and explosive hazardous gas, once it is hardly imaginable that gas leakage damage sequence occurs.
Summary of the invention
For the deficiency that prior art exists, the utility model provides a kind of gasification chilling train, while ensure that each equipment normally works, enormously simplify pipeline to arrange, reduce the usage quantity of pipeline upper connector, reduce system failure rate, improve production security.
Concrete technical scheme is: a kind of gasification chilling train, comprise chill air compressor, vapourizing furnace, ash disposal system, wash system and surge tank, wash system and surge tank by the first pipeline and the second pipeline in parallel, then successively with chill air compressor, vapourizing furnace and ash disposal system form series loop by pipeline, first pipeline is provided with the first pneumatic adjusting valve and the first outlet non-return valve, first outlet non-return valve is positioned near surge tank one end, first pipeline is also provided with the bypass hand valve in parallel with the first pneumatic adjusting valve, second pipeline is provided with the second pneumatic adjusting valve and the second outlet non-return valve, second outlet non-return valve is positioned near surge tank one end, pipeline between chill air compressor and vapourizing furnace is provided with the 3rd pneumatic adjusting valve and the 3rd outlet non-return valve, 3rd outlet non-return valve is near vapourizing furnace one end.
In described surge tank, gas temperature is 210 °.
Described first pneumatic adjusting valve and the second pneumatic adjusting valve operationally aperture are more than or equal to 30%.
The utility model structure is simple, and easy to use, security is high, and the basis that existing equipment normally works deletes whole piece surge pipeline, and three valves and three vacuum breaker, reduce use cost, decrease potential safety hazard simultaneously, improve production security.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of gasification chilling train, comprise chill air compressor 1, vapourizing furnace 2, ash disposal system 3, wash system 4 and surge tank 5, wash system 4 and surge tank 5 by the first pipeline 6 and the second pipeline 7 in parallel, then successively with chill air compressor 1, vapourizing furnace 2 and ash disposal system 3 form series loop by pipeline, first pipeline 6 is provided with the first pneumatic adjusting valve 8 and the first outlet non-return valve 9, first outlet non-return valve 9 is positioned near surge tank 5 one end, first pipeline 6 is also provided with the bypass hand valve 10 in parallel with the first pneumatic adjusting valve 8, second pipeline 7 is provided with the second pneumatic adjusting valve 11 and the second outlet non-return valve 12, second outlet non-return valve 12 is positioned near surge tank 5 one end, pipeline between chill air compressor 1 and vapourizing furnace 2 is provided with the 3rd pneumatic adjusting valve 13 and the 3rd outlet non-return valve 14, 3rd outlet non-return valve 14 is near vapourizing furnace 2 one end.
Gas temperature from ash disposal system 3 is 300 °, and point two portions enter in surge tank 5, a part is directly arrived by the first pipeline 6, another part is introduced into the system of washing 4, then enter in surge tank 5 through the second pipeline 7, it is 165 ° from the gas temperature washed system 4 out, the gas volume controlling by the first pipeline 6 and the second pipeline 7 respectively by regulating the first pneumatic adjusting valve 8 and the second pneumatic adjusting valve 11, making gas arrive the rear temperature of mixing in surge tank 5 is 210 °, first pneumatic adjusting valve 8 and the second pneumatic adjusting valve 11 operationally aperture are more than or equal to 30%, ensure the gas throughput in pipeline, if it is still on the low side the first pneumatic adjusting valve 8 to be opened completely gas temperature in rear surge tank 5, now bypass hand valve 10 is opened, increase the gas flow of the first pipeline 6, gas in surge tank 5 enters vapourizing furnace 2 Quench after chill air compressor 1 pressurizes, by the first pneumatic adjusting valve 8 after chill air compressor 1 stops pressure release, second pneumatic adjusting valve 11 and the 3rd pneumatic adjusting valve 13 are closed, thus chill air compressor 1 is isolated, due to gas after washing system 4 with a small amount of water, therefore native system needs timing drainage, anti-sealing enters in chill air compressor 1 and causes running status to fluctuate.
