Differential rotating bed continuous feeding biomass gasification furnace

Abstract

The invention discloses a differential rotating bed continuous feeding biomass gasification furnace, and mainly relates to the technical field of energy science. The furnace comprises a furnace body,an air distribution disc and an air disc driving device for driving the air distribution disc to rotate are arranged in the furnace body, the furnace body comprises a cylinder body and a cylinder bodysupport located on the outer side of the cylinder body and used for supporting the cylinder body, an ash bin is arranged on the lower side of the cylinder body, and an ash bin driving device for driving the ash bin to rotate is arranged on the cylinder body support. A blanking pipe is arranged at the top of the furnace body, a conical distributor is arranged on the lower side of the blanking pipe, a spiral sealing feeder is arranged at the top of the blanking pipe, a buffer bin is arranged at the top of the end, away from the blanking pipe, of the spiral sealing feeder, and a feeding barrel with the closed bottom end is obliquely arranged on one side of the buffer bin. The biomass gasification furnace can realize continuous sealed feeding in the gasification process, can effectively prevent partial burning deviation and burning through, is easy to control the thickness of an ash layer, can enhance the disturbance of biomass in the furnace, and improves the gasification strength.

Description

technical field

[0001] The invention relates to the field of energy science and technology, in particular to a differential rotary bed continuous feed biomass gasifier. Background technique

[0002] Biomass gasification technology is a rapid and reliable biomass energy utilization technology developed in recent years. It is an efficient way of biomass energy conversion. At present, the carrier selected by domestic mainstream biomass gasification technology is circulating flow Bed gasifier and updraft fixed bed gasifier, but there are a series of problems in use:

[0003] 1) The common problems of circulating fluidized bed gasifiers are low gasification intensity and low utilization rate of biomass gasification equipment, which lead to high operation difficulty and high maintenance cost. The ash content in the produced gas is large, which will cause serious wear and tear on the components, which is not conducive to the large-scale promotion and use of equipment;
