Abstract

The invention relates to a fixed bed biomass gasification furnace sealing ash removing device which comprises a drive device (1). The invention is characterized in that the invention also comprises an upper channel lock gate hatch(7) and a lower channel turning door (10) and a sealing element correspondingly arranged below the upper channel lock gate hatch(7); wherein, the upper channel lock gate hatch(7) comprises two lock gate hatches moving oppositely, two lock gate hatch sealing slots formed by a folded plate with a channel steel shape (6) respectively welded at the back part of the lock gate hatches, two lateral sealing frames (12) respectively at two sides of the lock gate hatches, two lock gate hatch drive connecting rods (3) respectively connected with the lock gate hatches as well as two lock gate hatch guiding wheels (5) respectively connected with the lock gate hatch drive connecting rods (3). The invention combines the characteristics of the biomass ash and the gasification furnace to lead the biomass ash to be discharged through intermission and sealing, thus ensuring the quality of the gasified gas.

Description

technical field [0001] The invention relates to the fields of environmental protection, new energy and the like, in particular to a sealed ash removal device applied to a fixed-bed biomass gasification furnace. Background technique [0002] The sealing of biomass gasifier ash removal has always been a difficult problem to solve. In the fixed bed biomass gasification furnace, due to the negative pressure inside the furnace, if it is not sealed during the ash removal process, the outside air will enter the furnace body, change the composition of the gasification gas, and even react with the gasification gas, reducing the The gasification gas quality will burn out the furnace body and equipment. In addition, because biomass ash has the characteristics of loose structure, low density and high temperature, it is very difficult to use ash for self-sealing, gravity sealing, and water sealing. Therefore, it is necessary to develop a new device for sealing biomass ash. Contents o...
