1. gas-liquid contanct equipment that is used for removing oxysulfide from flue gas, this equipment comprises the tower with gas feed and outlet;

  • Gas scrubbing district between import and outlet;

    Be used for providing the device of the liquid slurry reactant that absorbs oxysulfide to the gas scrubbing district;

    Be positioned at the reaction zone of below, the inherent gas scrubbing of tower district, be used to collect the liquid slurry reactant of partial reaction and from the product of the washing in gas scrubbing district, the product of described reactant and washing rises to the setting liquid level at reaction zone;

    Be used for oxidation air is introduced in the liquid slurry of reaction zone, force the device of the sulphur compound in-situ oxidation that is collected in the reaction zone;

    Wall with gas scrubbing district and reaction zone separation and connection, this wall prevents that oxidation air from entering the gas scrubbing district, and extend in the liquid slurry, forming and keeping below the required normal depth of liquid slurry sealing, thereby get rid of flue gas basically and leak in the reaction zone, the liquid slurry reactant of partial reaction and the product of washing can be discharged in the described reaction zone.
