Title: Dry scrubber and its regenerating method
Inventor: KATO NAOMI
IPC: B01D53/81
Filed: 2001-06-07
Abstract: PROBLEM TO BE SOLVED: To provide a dry scrubber in which a plurality of filter parts each having an ion exchange fiber are arranged in parallel and the mist of a regenerating liquid is prevented by a simple structure from scattering toward the downstream side in large quantities when the filter parts are regenerated. SOLUTION: The regenerating liquid from a pump 11 is sprayed toward the filter parts 3 to be regenerated while the supply of the gas to be treated to the parts 3 is continued as it is. As a result, the ion exchange fiber housed in the parts 3 becomes in a wet state by spraying the regenerating liquid and the resistance to the flow rate of the gas to be treated increases much more when it is in the dry state. Thereby, the flow rate of the gas to be treated toward the parts 3 during the regeneration lowers automatically so that the mist of the regenerating liquid can be restrained from scattering toward the downstream side.
