【発明の名称】煙道ガス処理スクラバー
Document Type and Number:
Japanese Patent JP2001520107
Kind Code:
A
Abstract:
The invention relates to a novel and most efficient scrubber for the treatment of flue gases from power generation plants or from chemical plants, in order to absorb objectionable impurities, such as SO2, SO3, HCl, nitrous oxides, into a water-based solution, in which solids are not substantially precipitated. The novel scrubber comprises: a horizontal chamber, with a basis rectangular vertical cross section, divided along the horizontal axis into a number of compartments by vertically-draining demisters covering the whole vertical cross section; a shallow liquid-collecting sump in each compartment, which can be sloped in any convenient direction; a pump which distributes the liquid from each such sump, at a controlled flow-rate to a series of spray nozzles in the same compartment, generating 3-5 vertical "falling curtains" perpendicularly to the gas flow and covering the whole vertical cross section, while the liquid drops fall back into the sump.
