A kind of biomass gas dedusting and decoking unit

Technical field

The utility model relates to a kind of dedusting decoking device, particularly a kind of biomass gas dedusting and decoking unit.

Technical background

Biomass energy is a kind of renewable energy source.In recent years the biomass gasification technology of Chu Xianing is meant that in certain geographic range, comparatively agricultural wastes such as dispersive husk, straw, bagasse, wood chip are concentrated and are converted into biomass fuel, a kind of technology that is used again.Biomass are in gasification, dust that produces owing to Pintsch process and tar are present in the biological fuel gas with the form of particulate, the tar particulate can regelation become solid-state tar when temperature reduces, and combine the mechanical position of blocking pipe and badly damaged gas engine with moist dust particle in the combustion gas.Therefore; how dust in the biological fuel gas and tar particulate are removed; guarantee that biological fuel gas is producing by the gas engine group in the process of electric energy; not causing gas engine to damage or shut down because of dust, tar condense, is a difficult problem of facing during the gasifying biomass generation technology is used.

In order to remove dust, the tar particulate in the biological fuel gas; present most gasifying biomass generating set manufacturer adopts mechanical means; this method can only reduce the content of dust and tar particulate in the combustion gas to a certain extent; therefore the gas engine group is after moving through one period short period of time; at last still can because of dust and the tar particulate is cumulative break down, cause shutting down.And the burnt equipment of general electric fishing, though occur already, but this series products is is all designed and developed at large-scale thermal power plant, chemical plant, coal washery, and the gas flow of general gasifying biomass power generation project is less, and the gas property that biological fuel gas and thermal power plant, chemical plant need be handled has very big difference, therefore, also do not design effective dedusting decoking device of production in the market at biological fuel gas.

Working process of the present utility model is, start high-voltage power supply, corona polar line is generated an electromagnetic field in steel pipe, after the combustion gas through cooling and purifying enters casing lower floor from inlet pipe, the combustion gas pilot hole is input in the steel pipe equably on air distribution plate, when steel pipe is passed through in combustion gas, combustion gas obtains enough energy under the effect of electromagnetic field becomes unbound electron and conducts electricity, the burnt particle of dirt in the combustion gas can be adsorbed on the charged particle, electrochondria going along with moves to the steel pipe inwall, and be adsorbed on the steel pipe inwall, along with the burnt particle of dirt gathering at the steel pipe inwall, can come off in deadweight effect and the burnt particle of when outage dirt, and the combustion gas that removes dust removal Jiao enters the casing upper strata and is input in the gas electricity generator from escape pipe.Disconnect high-voltage power supply, open nozzle, can clean box house with hot water, sewage is discharged from water discharge valve.When gaseous-pressure was excessive in the casing, explosion trap can be opened automatically, and the casing upper strata is communicated with atmosphere, prevented blast, utilized working hole can observe its working condition and carried out internal cleaning and maintenance.

The utility model compact construction, safe and reliable, easy to maintenance.The power supply of offer 3KW during use, daily requirement uses about 1 cubic metre of hot water that system is washed, approximately per hour 3500 cubic metres of its maximum combustion gas processing poweies, combustion gas quality satisfies the gas electricity generator service requirements fully, can guarantee the gas electricity generator works better.
