Reciprocating grate of biomass gasification furnace

Abstract

The invention discloses a reciprocating grate of a biomass gasification furnace. The reciprocating grate of the biomass gasification furnace comprises a support and a plurality of grate bridges which are installed in the support side by side. A swing arm is fixedly connected to the end of each grate bridge. All the swing arms are connected with the same linkage rod. One end of the linkage rod is connected with a power source through a push-and-pull power head. The linkage rod is pushed and pulled by the power source through the push-and-pull power head to pull the swing arms to reciprocate, and then the grate bridges are driven to rotate in a reciprocating mode, so that gaps between the grate bridges are made to become large and small alternately. The reciprocating grate of the biomass gasification furnace is compact in structure and easy and convenient to operate, and the slag discharge gaps can change dynamically; the ash passing capacity is high, and the wind resistance is small; the covering performance is good when deslagging is not conducted; due to the fact that the reciprocating grate is of a hollow structure, the weight is low; the service life of equipment is long; the reciprocating grate can turn in a reciprocating mode so that connection of water pipes can be simplified, and the fault rate is decreased; continuous deslagging can be conducted without stopping the furnace, and thus the production stability is guaranteed; the labor intensity of operators is relieved, fuel waste caused by starting of the stopped furnace is also reduced, and accordingly economic benefits are greatly increased.

Description

technical field [0001] The invention relates to the field of biomass gasification, in particular to a fire grate of a biomass gasification furnace. Background technique [0002] Biomass fuel, as a kind of renewable energy that can turn waste into treasure and is cheap, is more and more widely used, but direct burning of biomass fuel will produce a large amount of smoke and dust, which will pollute the atmosphere, and the use of biomass fuel gas It is a scientific and environmentally friendly way to utilize biomass energy, and it is attracting more and more attention. [0003] At present, the research and development of biomass gasification furnace is still in a very immature primary stage. Most of the ash produced by gasification needs to be shut down regularly for manual excavation, which not only affects production but also wastes energy; grid-type grate is also used. Carry out slagging, but its structure is bulky, slagging is not thorough, and the fire grate is not durab...

[0003] At present, the research and development of biomass gasification furnace is still in a very immature primary stage. Most of the ash produced by gasification needs to be shut down regularly for manual excavation, which not only affects production but also wastes energy; grid-type grate is also used. Slagging is carried out, but its structure is bulky, the slagging is not complete, and the grate is not durable
