Description
Technical field
The present invention relates to coal chemical industry and power generation technical field of producing, in particular to a kind of space flight furnace gasifying powder coal devices
High pressure flash stripper bulky grain ash separation system.
Background technique
High pressure flash stripper is the important equipment in space flight furnace gasifying powder coal device Slag-water system, and influences coal gasification
Device is continuous, one of the key equipment of stable operation, plays a very important role to the long-term operation of whole device.High pressure
The stripper biggish low-quality steam of dust burdening that on the one hand recycling hp flash drum discharges is flashed, reduces the loss of heat, together
When improve grey coolant-temperature gage in advance, enhance deaerating effect, improve the use environment of follow-up equipment, improve the comprehensive of space flight producer gasization operation
Close benefit.
High pressure flash stripper dodges pressure tank in reception high pressure and carrys out steam, and process water is heated to 130 DEG C or so, is changed in stripping
In thermal process, the dissolved oxygen in technique buck is stripped out, from bottom to top with the fixed gas in saturated vapor together from tower top
Tower out.A large amount of ash particle also enters stripper simultaneously in the steam that hp flash drum comes, and enters height together with technique buck
Grey water pump and gasified boiler system are pressed, pipeline in water system, fouling exacerbation in equipment is caused, increases the mill of high pressure buck impeller of pump
Erosion, causes high pressure buck impeller of pump to break, influences the stable operation of device when serious.So how big in technique buck
Grain ash, which is separated, seems extremely important.
Summary of the invention
Technical problem solved by the invention is to provide a kind of space flight furnace gasifying powder coal device high pressure flash stripper big
Particle ash separation system, to solve the disadvantage in above-mentioned background technique.
Technical problem solved by the invention is realized using following technical scheme: a kind of raising space flight furnace coal gasification dress
Set high pressure flash stripper bulky grain ash separation system, including high pressure flash stripper, dump valve, dump pond,
Automatic control and adjustment device, vacuum flashing system, purified water reception device, connecting pipe, flow detector.In the high pressure
It flashes and is equipped with connecting pipe between stripper and the vacuum flashing system, the both ends of the connecting pipe are separately connected the height
The water outlet of pressure flash distillation stripper and the water inlet of vacuum flashing system, are equipped with automatic control and adjustment in the connecting pipe and fill
It sets and flow detector, is equipped with dump valve and dump in the other side of the high pressure flash stripper water outlet
Pond.
Heretofore described high pressure flash stripper tapering is equipped with discharge outlet, and the connecting pipe is from high pressure flash
Stripper tapering discharge outlet is drawn, and the connecting pipe is equipped with automatic control and adjustment device and flow detector.
Heretofore described connecting pipe water outlet is connected with vacuum flashing system.
Beneficial effects of the present invention: high pressure flash stripper contains a large amount of ash particle steam recycling flash tank
And the internal black dirt formed of stripping, vacuum flashing system is entered by separator, then battery limit (BL) is finally discharged by flash separation.
Space flight furnace gasifying powder coal device high pressure flash stripper bulky grain ash separation system can effectively reduce work in stripper operation
The black dirt and bulky grain ash of entrainment in skill buck mitigate pipeline in high pressure grey water pump and gasified boiler system ash water system, set
Standby interior fouling, avoids destruction of the big ash particle to components such as high pressure buck impellers of pump, and stabilising arrangement operation improves device operation
Efficiency.
Present invention has the advantage that:
It realizes efficiently separating for the black dirt and bulky grain ash and process water in high pressure flash stripper, mitigates high pressure buck
Pipeline, fouling in equipment, avoid big ash particle to components such as high pressure buck impellers of pump in pump and gasified boiler system ash water system
Destruction, the operational efficiency of lifting device.
