The invention discloses a biomass thermal cracking water-cooling carbon-gas co-production gasification system which comprises a gasification furnace, a cooling water tank and a plurality of groups ofgas purification systems. Each gas purification system comprises a sand filtration tank, a cooling tank, a filter, a centrifugal separator, a Roots blower and a gas storage tank which are sequentiallyconnected in series by adopting a gas delivery pipe B; a gas outlet of the gasification furnace is connected with a gas inlet of the sand filtration tank through a gas conveying pipe A; a ventilationvalve is arranged on the gas conveying pipe A; a coke outlet of a coke outlet hopper and the bottom ends of the sand filtration tank, the cooling tank, the filter and the centrifugal separator are connected with a liquid accumulation box through liquid discharging pipes respectively, and a liquid changing opening in the bottom of the liquid accumulation box and a liquid releasing opening of the gas storage tank are connected with a liquid storage pool through liquid changing pipelines. According to the biomass thermal cracking water-cooling carbon-gas co-production gasification system, efficient separation of biomass gas generated by the gasification furnace and other impurities is achieved; compared with the prior art, the disclosed system has the following advantages: purification efficiency of the biomass gas is remarkably improved, the purity of the biomass gas is improved, and then the combustion efficiency of the biomass gas is improved.
Description
Technical field [0001] The invention relates to the field of biomass fuel gas preparation and purification systems, in particular to a biomass thermal cracking water-cooled carbon gas co-production gasification system. Background technique [0002] The efficient conversion of biomass energy has now become a major research topic in the energy field. Currently, biomass energy conversion technologies mainly include biomass gasification, liquefaction, solidification, and direct combustion technologies. Among them, biomass gasification technology is an important means to realize biomass energy conversion. Biomass gasification refers to the process in which biomass raw materials (straw, sawdust, firewood, etc.) are subjected to compression molding or simple crushing treatment, and then sent to the gasifier for cracking under anoxic conditions. The principle is Under certain thermodynamic conditions, with the help of part of air or oxygen and water vapor, the high polymer of biomass is...
