DESULFURIZATION SYSTEM OF SYNGAS FROM COAL GASIFIER

摘要

Desulfurization refining system of the coal gasifier synthesis gas of the present invention is formed on one side and the gas inlet 104 is formed on the other side and the high-temperature and high-pressure synthesis gas inlet is discharged to the exhaust gas purified in high purity 104 and And a syngas purification apparatus 100 composed of a pipe portion 110 formed of a plurality of U-shaped pipes between the gas inlet and the outlet 102, 104. Each U-shaped pipe is provided with a venturi part 112 and passes through the primary cleaning pipe 114 through which the synthesis gas introduced through the gas inlet 102 flows downward, and the primary cleaning pipe 114. Synthesis gas is composed of a secondary cleaning pipe 116 flowing upward, the first vertical injection of the cleaning liquid in the venturi unit 112 with respect to the downward flow of the synthesis gas in the primary cleaning pipe 114, and the secondary cleaning pipe ( Synthetic gas is cooled, washed and collected by second reverse injection of the cleaning liquid with respect to the upward flow of the syngas in 116).;According to the present invention, continuous and high purity purification is possible, moreover, it is more economical than using a combination of existing commercialized processes to achieve the same effect, and also connects two or more stages of the same type of syngas purification apparatus. It is possible to have the effect of excellent scalability.
