Description

Technical Field

[0001] The utility model relates to the technical field of gasifiers, in particular to a biomass pyrolysis gasifier. Background Technique

[0002] At present, the biomass pyrolysis gasification technology mainly uses partial biomass materials for low-oxygen combustion, and then uses the heat and remaining oxygen in its flue gas to pyrolyze and gasify the remaining biomass materials. The main structure is to feed materials from the upper part or side of a single gasifier, and inject external high-temperature flue gas into the furnace to achieve high-temperature pyrolysis of biomass and generate combustible gas.

[0003] There are mainly three types of existing gasifiers. For example, in the cyclone type biomass high-temperature pyrolysis gasifier, gas fuel combustion chambers are arranged on both sides of the furnace body. During operation, the fuel in the gas combustion chamber burns to generate high-temperature and low-oxygen flue gas, which is sprayed tangentially at high speed into the biomass furnace pyrolysis gasification chamber to quickly pyrolyze the biomass materials. Secondly, in the two-stage biomass cyclone high-temperature pyrolysis gasifier, the furnace body structure is of two-stage type, with an upper high-temperature pyrolysis chamber and a lower steam spraying for further pyrolysis, effectively utilizing the fixed carbon in the residue. This furnace body also adopts external fuel to generate high-temperature flue gas and inject it into the pyrolysis furnace. Finally, in the three-stage biomass pyrolysis gasifier, a catalytic cracking section is added in the middle, which is beneficial to increasing the yield of combustible gas.

[0004] Most of the existing gasifiers adopt manual feeding, with low efficiency, and the materials are easy to accumulate, which is likely to cause other problems. Content of the Utility Model
