Cyclone type biomass high temperature pyrolysis gasification furnace

Abstract

The invention relates to a whirlwind air type biomass high temperature pyolyzing gasification furnace which comprises a cylinder and a whirlwind air high temperature pyolyzing gasification furnace chamber with a form that conic cylinders are combined up and down. The upper part of the gasification furnace is provided with a biomass storage hopper, a worm distributor and a tapered material dropping pipe, the lower part is provided with a clinker discharge pipe and a clinker box, the gasification furnace is internally provided with a vertical biomass gas discharge pipe which is coaxial with the gasification furnace, and the two sides outside the gasification furnace are respectively provided with a gas fuel combustion chamber. When in running, high temperature and low oxygen flue gas generated by fuel burnt in the gas fuel combustion chamber is injected into the whirlwind air type biomass high temperature pyolyzing gasification furnace chamber along the tangential direction in a way of high-velocity jet, so that strong whirlwind volution is formed; meanwhile, the flue gas is rapidly mixed with biomass material and is fully pyrolyzed and gasified, and the generated biomass gas is discharged out of the whirlwind pyolyzing gasification furnace through the biomass gas discharge pipe. The clinker formed by the biomass material which is pyrolyzed and gasified in the whirlwind pyolyzing gasification furnace chamber is discharged into the clinker box through the clinker discharge pipe.

Description

technical field [0001] The invention relates to a biomass gasification furnace, in particular to a cyclone type biomass high-temperature pyrolysis gasification furnace. Background technique [0002] Biomass energy refers to the energy contained in biomass (generally referring to all living and growing organic substances), which is the energy stored in biomass by green plants converting solar energy into chemical energy through chlorophyll. Therefore, biomass energy is renewable energy. At present, biomass as primary energy usually refers to agricultural and forestry wastes, such as sawdust, bark, rice husk, straw, peanut shells and bagasse. In terms of its energy equivalent, biomass energy ranks fourth after coal, oil, and natural gas. In the world's energy consumption, biomass accounts for 14% of the total energy consumption. [0003] There are many forms of utilization of biomass energy. Biomass gasification technology converts solid biomass into clean gaseous fuel thro...
