Biomass gasification burner

Abstract

The invention relates to the field of biomass gasification equipment, in particular to a biomass gasification burner which mainly comprises a machine frame, a hearth, a cyclone separator, a hydraulic slagging deashing mechanism, a first water tank, a second water tank and a slag collector. The hydraulic slagging deashing mechanism is arranged on the lower side in the hearth, the slag collector is arranged on the lower side of the hydraulic slagging deashing mechanism and surrounded by the lower portion of the hearth, the second water tank sleeves the slag collector, an air inlet of the cyclone separator is connected with the inside of the hearth, the lower portion of the hearth extends into water of the second water tank, the slag collector extends into water of the first water tank, and an ash dropping port of the cyclone separator extends into the water of the second water tank, so that a sealed water sealing environment is formed in the hearth. When pressure of gas in the hearth is instable or even deflagration occurs, part of air pressure released in a furnace passes screen holes in a fire grate in the hydraulic slagging deashing mechanism and enters the first water tank along the slag collector, another part of air pressure enters the second water tank along the ash dropping port of the cyclone separator, the goals of anti-explosion and pressure relief are achieved, and a device is protected from damage.

Description

technical field [0001] The invention relates to the field of biomass gasification equipment, in particular to a biomass gasification burner. Background technique [0002] At present, the biomass gasification burner is to send biomass gasification raw materials (such as straw, wood chips, wood blocks, granules, briquettes, etc.) Carbon, hydrogen, oxygen and other elements undergo thermal cracking and transform into combustible gases such as CO, H2, CH4, etc., and then burn through the gas nozzle to release heat energy, but when the combustible gas in the furnace is in a high-temperature closed environment, Under certain circumstances, it is easy to explode, causing equipment damage or even safety accidents. Contents of the invention [0003] In view of this, it is necessary to provide a biomass gasification burner for the above problems. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A biomass gasification c...
