Biomass Energy Utilization mode is varied, and to be wherein converted to clean fuel gas utilization be one of effective means in gasification.Gasifying biomass utilizes two key points of technology: the one, and biomass gasification reaction stove, the 2nd, the purification that combustion gas is coal-tar middle oil.In the combustion gas that biogas is combined to, contain a variety of impurity, the target of gas-purification is exactly the feature according to gasifying process, effective impurity removal processes reasonable in design, guarantees that the rear combustion gas of gasification utilizes equipment can not cause because of the existence of impurity the problems such as wearing and tearing, corrosion and pollution.
The decoking technology that tradition adopts has the physical methods such as washing, filter at low temperature and static decoking.The main drawback of tar water-washing technique is to have a large amount of sewage to produce, necessary supporting corresponding complex process, operation and the costly wastewater treatment equipment of laid down cost.
Tar filter at low temperature, because filtering material resistance is large, easily stops up, and changes frequently for necessary must adopt switching technique (a preparation and a use) and the filtering material moving continuously, and material expends many, and labour intensity is too large.
Static decoking technology is strict to inlet gas dust, tar content and temperature requirement, adopts static decoking technical equipment in its equipment, has possessed two key elements of blast three elements, fires thing and burning things which may cause a fire disaster.And to operating biomass gasification system, guarantee for a long time that in its inflammable gas, oxygen level is very difficult lower than the requirement of electric fishing.Explosion-proof and decoking does not have good way at present in actual applications.
Physics decoking is just separated tar by different approach from combustion gas, most methods using tar separation out after as waste discharge, this is on the one hand wasted the contained energy of tar, meanwhile, also can produce new pollution if dealt with improperly.
Tar catalytic reforming cracking technique is to be inflammable gas by catalytic cracking of tar, and the inflammable gas of reforming out through cracking utilizes together with biological fuel gas.Tar catalytic reforming cracking technique is that biomass gas tar oil purifies best approach and development trend, not yet has ripe practical catalytic cracking reaction device to emerge at present.
