Title:
SYSTEM FOR REMOVING CONTAMINANT IN AIR
Document Type and Number:
Japanese Patent JP2020137686
Kind Code:
A
Abstract:
To always highly maintain performance for removing a water-soluble component in the air and improve maintainability, and reduce running cost.SOLUTION: A system for removing a contaminant in the air includes: an air washer 11 at a former stage using a chemical solution containing at least either an alkaline solution or an acidic solution as an absorbent; a chemical solution supply device 12 for supplying a chemical solution to the air washer 11 at the former stage; an air washer 13 as a later stage which is arranged on the downstream side in an air circulation direction of the air washer 11 at the former stage and uses pure water as an absorbent; an ion exchange resin 14 that is at least either a cation exchange resin and an anion exchange resin through which the absorbent of the air washer 13 at the later stage passes; and a control unit 16 which estimates concentration of a contaminant that flows into the air washer 11 at the former stage and is contained in the air on the basis of conductivity of the absorbent passing through the ion exchange resin 14 and thereby calculates an amount of the chemical solution supplied to the air washer 11 at the former stage from the chemical solution supply device 12.SELECTED DRAWING: Figure 1
