Abstract

The invention relates to an apparatus for converting a tar component and carbonaceous particles in raw gas, and a method thereof. The conversion apparatus comprises a conversion system, a material return system and a material sealing system. The conversion system is mainly composed of a solid particle distribution zone, a partial oxidation zone and an advanced treatment zone. The material return system is composed of a gas-solid shunting device, a solid particle trapping device and a vertical dipleg. The material sealing system is composed of a seal level control device, an annular seal and a material return inclined tube. A partial oxidation reduction reaction of a gasification agent, and the tar component and carbonaceous particles carried in the raw gas is carried out to convert the tar component and the carbonaceous particles into gas, so the advanced conversion treatment of the tar component and the carbonaceous particles in the raw gas is realized, and the energy conversion efficiency is greatly improved. The apparatus and the method have the technical advantages of simple operation process, low apparatus investment and running cost, high conversion rate and the like.

Description

technical field [0001] The invention relates to an advanced purification treatment technology for crude synthesis gas produced from coal and biomass, in particular to a conversion device and method for tar components and carbon-containing particles in crude gas. Background technique [0002] Clean coal technology mainly refers to the process technology system used to produce various petroleum-based alternative fuels and high value-added chemical products through coal pyrolysis and gasification processes, carbon-chemical and optimized integration of different unit processes. Coal gasification technology is the core and one of the key technologies of clean coal technology. Coal gasification products are widely used in power production, urban heating, fuel cells, liquid fuels, and synthesis of chemical raw materials. In this sense, coal gasification is an important basis for the development of coal-based polygeneration process systems (such as IGCC), coal-based chemical and cl...
