GAS-LIQUID-SOLID SEPARATOR, GAS-LIQUID SEPARATOR AND PLASMA DESULPHURATION AND DENITRATION APPARATUS COMPRISING SAME

摘要

Provided are a gas-liquid-solid separator (3), a gas-liquid separator (5) and a plasma desulphuration and denitration apparatus. The gas-liquid-solid separator (3) comprises a cylindrical shell (35), a filter core nested in the shell (35) and a water discharge valve (38), wherein a gas inlet (351) having a flange and a gas outlet (352) having a flange are provided on a side face of the shell (35), a cyclone channel is formed between the shell (35) and the filter core, the filter core comprises three coaxially nested columnar filter barrels, which are a sintered filter (33), an inner filter barrel (34) and an outer filter barrel (36) successively from inside to outside, and a plurality of filter holes are arranged on both the inner filter barrel (34) and the outer filter barrel (36), and can be aligned or staggered to each other when the inner filter barrel (34) and the outer filter barrel (36) rotate relative to each other. The gas-liquid separator (5) has two coaxially nested columnar filter barrels (52, 53), and a plurality of filter holes are arranged on both the columnar filter barrels (52, 53) and can be aligned or staggered to each other when the inner filter barrel (52) and the outer filter barrel (53) rotate relative to each other. The plasma desulphuration and denitration apparatus comprises the gas-liquid-solid separator (3) and the gas-liquid separator (5).
