specific Embodiment 1

[0055] 1) Add construction residues into the storage bin 111 of the pretreatment chamber 110 of the furnace body 100 from the feed port 150, evaporate and dry at a temperature of 150°C, and then undergo a pyrolysis reaction at a temperature of 450°C. Combustible gas, tar and charcoal are generated from the pyrolysis of construction residues.

[0056] 2) The combustible gas, tar and char enter into the oxidation incineration chamber 120 through the separator 160, and undergo an oxidation reaction under the temperature of 1100°C and the action of air to obtain carbon dioxide, water vapor, char and tar.

[0057] 3) The carbon dioxide, water vapor and tar enter the reduction cracking chamber 130 downward, and a reduction reaction occurs at a temperature of 1000°C. Under the high-temperature anaerobic state, the carbon dioxide, water vapor and carbon undergo a reduction reaction to obtain carbon monoxide, hydrogen, and methane And carbon, tar and water vapor are reacted and cracked...

Description

technical field [0001] The invention relates to the technical field of biomass energy, in particular to a self-tar removal type biomass gasification reaction system and a method thereof. Background technique [0002] Biomass energy is the solar energy fixed on the earth through the photosynthesis of plants, which has the advantages of renewability, low pollution and wide distribution. Biomass energy can be converted into clean fuel through biomass energy conversion technology, which can be used to replace coal, oil and natural gas to produce electricity. The use of biomass energy can protect national energy resources, reduce damage to the environment, and solve air pollution and other issues. [0003] Biomass gasification is a method of biomass conversion. After the biomass raw material is processed, it is burned in an anoxic furnace to obtain combustible gas. However, the traditional biomass gasifier will produce more tar during the gasification reaction. The tar is corr...
