<p>PURPOSE:To remove fine liquid drops by providing a liquid drop generator to the lower part of a wetted wall column, suspending a cathode bar to the central part of the column and impressing a voltage to said bar and column in such a manner that the column wall acts as an anode thereby forming an electrostatic liquid drop separator. CONSTITUTION:Gas to be treated enters the column 1 from a gas duct 3a and is mixed with the liquid ejected from a water pipe 3b of a spray generator 3 provided in the lower part of the column in an injection part 3c. The mixture ascends in the form of the gas contg. the fine liquid drops in the column 1. THe voltage is impressed between the cathode bar 4 and the wetted wall 2 acting as the anode. The fine liquid drops charged negative is attracted in the state of contg. an acidic gas, dust, etc., to the wetted wall anode. An absorbent liquid is injected from an annular spray generator 5 provided in the upper part of the column to drop the liquid from the upper part of the wetted column, by which the gas absorption is further executed.</p> |
