Description
Technical field
The utility model relates to the purifying processing device of gasifying biomass synthetic gas, refers to a kind of gasifying biomass synthetic gas flying dust high temperature tripping device particularly.
Technical background
Along with society growing to energy demand, promptly reducing as the fossil oil in main energy sources source.Therefore, seek a kind of reproducible substitute energy, become the focus of social common concern.The synthetic gas that utilizes gasifying biomass to produce carries out steam, the gas Combined circulating generation is a kind of important way that biomass are utilized.At present, available biomass fuel mainly contains rice husk, cotton stalk, rice straw, rape stalk and cornstalk etc.The common feature of these biomass fuels is that the combustible basis fugitive constituent is very high, reach more than 80%, be easy to catch fire and burn, but burning property is relatively poor, thereby in the synthetic gas that biomass gasifying furnace is produced, there are a large amount of flying dusts that does not burn and the higher solid particulate of concentration.These unburned carbon in flue dust are very high in the synthetic gas on the one hand, directly discharge the production efficiency that can influence biomass gasifying furnace; On the other hand, the solid particulate in the synthetic gas directly enters waste heat boiler, has brought difficulty can for the later purification dedusting operation of synthetic gas, but also has increased the Financial cost of producing and moving.
Summary of the invention
The purpose of this utility model is that a kind of gasifying biomass synthetic gas flying dust high temperature tripping device will be provided, this device can effectively reduce the concentration and the carbon content of flying dust in the gasifying biomass synthetic gas, improve the production efficiency of biomass gasifying furnace, and can simplify the later purification treatment process of the synthetic gas of producing.
For achieving the above object, the gasifying biomass synthetic gas flying dust high temperature tripping device that the utility model is designed comprises that the lower end is the scroll casing separator of boring bucket shape, and the tangential admission end of described scroll casing separator links to each other with an end of inlet flue duct; The middle part of described scroll casing separator is provided with the vertical centre tube, and the upper end of described vertical centre tube links to each other with an end of exhaust pass; The awl bucket shape lower end of described scroll casing separator links to each other with the upper end of standpipe, and the lower end of described standpipe links to each other by the upper end of material returning valve with the feed back inclined tube.
Further, the other end of described inlet flue duct links to each other with the syngas outlet of biomass gasifying furnace, can directly high-temperature synthesis gas be introduced in the scroll casing separator and separate.The other end of described exhaust pass links to each other with the synthetic gas waste heat boiler, can utilize the isolated high-temperature synthesis gas heating boiler of scroll casing separator, simplifies follow-up dedusting operation.The lower end of described feed back inclined tube links to each other with the burner hearth of biomass gasifying furnace, and macrobead flying dust that can carbon content is high is sent into circulating combustion in the biomass gasifying furnace, further improves the vaporization rate of biomass.
Principle of work of the present utility model is such: the synthetic gas that contains flying dust enters inlet flue duct from biomass gasifying furnace, tangentially enters scroll casing separator again; Synthetic gas swims to shell wall under centrifugal effect when doing to revolve motion in scroll casing separator, macrobead flying dust in the synthetic gas is separated to get off, reenter the biomass gasifying furnace combustion gasification by standpipe, material returning valve and feed back inclined tube successively, less fly ash granule then upwards flies out from the vertical centre tube, enters waste heat boiler and follow-up dedusting operation with synthetic gas from exhaust pass.
Advantage of the present utility model is: carry through the separating treatment of scroll casing separator and the circulation of feed back inclined tube, the unburned carbon in flue dust and the concentration of solid particles of biomass gasifying furnace reduce greatly, efficiency of dust collection can reach about 99%, help simplifying the follow-up purifying and dedusting operation of synthetic gas, significantly reduced production and running cost; Simultaneously that carbon content is high macrobead flying dust is sent into circulating combustion in the biomass gasifying furnace, has further improved the gasification efficiency of biomass gasifying furnace.
