WET SCRUBBER SYSTEM COMPRISING DILUTION APPARATUS OF PH ADJUSTER

摘要

A wet scrubber system comprising a dilution apparatus of a pH adjuster is provided to purify effectively exhaust gas by adjusting easily a flow rate of the pH adjuster and maintaining constantly pH of a process. A process water supply unit(10) supplies process water. Cations of the process water are removed by using a cation exchange resin. A pH adjuster storage unit(20) stores the pH adjuster of first density. A pH adjuster dilution unit(30) provides the pH adjuster of second density by diluting the pH adjuster of the first density. A pH measurement unit(40) measures pH of purification water as a mixture of the pH adjuster of the second density and the process water. A pH control valve(50) is controlled according to pH measured by the pH measurement unit.
