Flame-retardant purification device used during biomass gasification and carbonization production

Abstract

The invention discloses a flame-retardant purification device used during biomass gasification and carbonization production. The flame-retardant purification device comprises a tank, a gas collectingcover and a liquid container. The gas collecting cover is mounted on the upper portion of the tank, the liquid container is mounted on the lower portion of the tank, a combustion gas outlet and an aeration blasting opening are formed in the gas collecting cover, a drain opening is formed in the lower portion of the liquid container, a gas inlet is formed in the tank, a gas and liquid separation structure which is connected with the gas inlet is arranged in the tank, the tar contents further can be lowered by the gas and liquid separation structure, a liquid inlet pipe is arranged on the tank,the tank can be filled with liquid by the liquid inlet pipe, a limit blasting stopping machine is arranged in the tank, and the liquid can be higher than an outlet of the gas and liquid separation structure under the control of the limit blasting stopping machine. The flame-retardant purification device has the advantages that liquid-phase dirt carried in gas can remain in the liquid container, the liquid level and the location of the outlet of the gas and liquid separation structure are controlled, and accordingly blasting stopping and purification effects can be realized by the flame-retardant purification device; outlets can be formed for shock waves by the aeration blasting opening under blasting conditions, backdraft of fire sources can be quickly prevented by the flame-retardant purification device in the integral design, and accordingly accidents can be prevented.

Description

Technical field [0001] The invention relates to a production equipment for biomass gasification and carbonization, in particular to a flame-retardant purification device in biomass gasification and carbonization production. Background technique [0002] After being crushed, the crop straw is transported to the pyrolysis gasification carbonization furnace, where it is dried, cracked, oxidized and reduced for a certain period of time to produce biomass straw charcoal and biomass gas. After the gas-solid phase separation, the biomass gas undergoes multi-stage dust reduction , Cooling treatment, to reach the use conditions of biomass generators, for biomass power generation. [0003] During the operation of the whole set of equipment, it will happen that the biomass gas production exceeds the rated generator gas usage. At this time, the surplus gas will be discharged and burned, and if there is a grid failure or other problems, the fan will lose transmission power At this time, the ig...

AI Technical Summary

Problems solved by technology

[0003] During the operation of the whole set of equipment, the gas production of biomass gas will exceed the rated generator gas consumption. At this time, the excess gas will be discharged for combustion, and if the power grid failure or other problems cause the fan to lose power At this time, the ignited gas will burn rapidly in the pipe network (called back-burning); if it is not dealt with at this time, equipment accidents will occur, causing equipment and personal safety to be threatened, but no such equipment or equipment has been seen in the prior art. method reporting
