Description
Technical field
The present invention relates to a kind of macro-organism matter gasification, dry distillation gas production engineering purification system.
Background technology
Gasifying biomass, dry distillation gas production central gas supply technology are the emerging technologies that China rises in recent ten years, have been widely applied to rural area new forms of energy construction and other field.This technology relates to system gas, purification, transmission & distribution three big system process.At present, gasifying biomass, dry distillation gas production central gas supply purification system adopt the direct spray washing of water more and adopt filtering material that filtering technology is carried out in combustion gas combustion gas is purified.There is following defective in this purification process: 1, the direct spray washing of water, though decontamination effect improving is better, can cause the secondary pollution of water, and can't reach environmental requirement; 2, adopt filtering material to filter, often resulting in blockage increases SR, so that system can't normally move, and must often change filtering material, trouble not only, and the management material that changes also is the secondary pollution source, also increases running cost simultaneously.3, for macro-organism matter gasification, dry distillation gas production system (greater than 2000m
3/ h), adopt media filtration technology difficulty unusually, investment is big, maintenance is difficult, running cost is high.
Summary of the invention
The technical problem that the present invention will solve provides a kind of simple in structure, easy to maintenance, safe and reliable macro-organism matter gasification, dry distillation gas production engineering purification system.
In order to solve the problem that prior art exists, the technical scheme that the present invention adopts is:
The gasification of macro-organism matter, dry distillation gas production engineering purification system; Include self cooling fly-ash separator, indirect cooler, air water separator, absorption tower and static decoking device; Described indirect cooler is shell and tube and is provided with tube side and shell side, and the inlet end of said self cooling fly-ash separator links to each other with vapourizing furnace, and the exit end of self cooling fly-ash separator links to each other with the tube side of indirect cooler; The exit end of tube side links to each other with the inlet end of air water separator; The shell side of indirect cooler links to each other with water circulating pump through water pipe, and the exit end of air water separator links to each other with the inlet end of static decoking device through the absorption tower, and the exit end of static decoking device links to each other with gas-holder.
The pipeline place, gas inlet of described static decoking device is equipped with the oxygen on line analyzer chain with static decoking device administration of power supply.
Advantage that the present invention had and effect:
Macro-organism matter gasification of the present invention, dry distillation gas production engineering purification system; Because adopt following structure: an end of self cooling fly-ash separator links to each other with vapourizing furnace, and the other end links to each other with the tube side of indirect cooler, and the exit end of tube side links to each other with air water separator; The shell side of indirect cooler links to each other with water circulating pump through water pipe; The exit end of air water separator links to each other with the static decoking device through the absorption tower, and the static decoking device links to each other with gas-holder, therefore has the characteristics that one-piece construction is simple, production cost is low.The present invention adopts indirect cooler to replace the direct spray washing equipment of water, has thoroughly solved recirculated water secondary pollution problem.Adopt air water separator, absorption tower and static decoking device gas-cleaning installation to replace the media filtration refining plant, improved purification efficiency, the stable 10mg/m that is controlled at of the burnt particle concentration of gas
3Below, remove frequent replacing filtrate trouble from, reduce equipment running cost, can realize extensive (2000m
3/ h) foundation and the safe and stable operation at gasification station or dry distillation gas production station.Because the oxygen on line analyzer chain with static decoking device administration of power supply is installed at pipeline place, the gas inlet of static decoking device, when static decoking device inlet gas oxygen level >=0.8%, cut off static decoking device mains automatically, safe.
