Problems solved by technology

However, at present, biomass gasifiers generally have uneven mixing of biomass raw materials and air in the gasifier due to unreasonable feeding methods, and the short gasification process leads to low biomass gasification efficiency.
In addition, the synthesis gas produced after the gasification reaction needs to be purified carefully to meet the usage requirements, and the equipment cost is high

Abstract

The invention discloses a double-cyclone biomass gasification furnace. The double-cyclone biomass gasification furnace comprises a furnace body, the top of the furnace body is provided with a feeding cyclone part, the side face of the feeding cyclone part is provided with an air inlet, and the top of the feeding cyclone part is provided with a biomass inlet; the middle of the furnace body is provided with an ignition device, and the ignition device is provided with an air outlet; the side face of the lower portion of the furnace body is provided with a filter cyclone part, the top of the filter cyclone part is provided with a coal gas outlet, the bottom of the filter cyclone part is provided with a material returning pipe which is connected with the bottom of the furnace body, and the filter cyclone part is connected with the furnace body through a gradually changing pipe; the bottom of the furnace body is provided with a screen mesh, and an ash collecting box is arranged below the screen mesh. Sufficient mixing of biomass and air can be realized through a vortex effect of the feeding cyclone part, the filter cyclone part can be used for separating fly ash particles in synthetic gas to purify the synthetic gas, and the double-cyclone biomass gasification furnace can achieve efficient reaction and deep purification of the biomass.

Description

technical field [0001] The invention belongs to the technical field of biomass gasification equipment, in particular, the invention relates to a double-cyclone biomass gasification furnace. Background technique [0002] Biomass gasifier is a kind of energy conversion equipment that uses waste biomass to produce combustible gas during oxygen-lean combustion. It is easy to use and low in cost, and plays an important role in the field of biomass utilization. However, at present, biomass gasifiers generally have uneven mixing of biomass raw materials and air in the gasifier due to unreasonable feeding methods, and the short gasification process leads to low biomass gasification efficiency. In addition, the synthesis gas produced after the gasification reaction needs to be purified carefully to meet the use requirements, and the equipment cost is high. Therefore, it is necessary to optimize and improve the feeding method and gas purification method of the biomass gasifier. Con...
