Title:
SYSTEM FOR RESTORING ACTIVE CARBON FILTER USED FOR TREATING PURIFIED WATER OR SEWAGE
Document Type and Number:
WIPO Patent Application WO/2014/171608
Kind Code:
A1
Abstract:
The present invention relates to a system for restoring an active carbon filter used for treating purified water or sewage through the steps of: purifying water by simultaneously supplying sewage and wastewater into a plurality of reaction towers (10), the inside of which is divided into a plurality of sections and each of the sections is filled with an active carbon filter; blocking the supply of sewage and wastewater into a reaction tower (10) requiring restoration from among the plurality of reaction towers (10); sequentially drying the active carbon filters filled inside each of the divided sections by sequentially supplying, into each of the divided sections inside of the reaction tower (10), air discharged through a blower (20) toward the reaction tower (10) requiring the restoration of the active carbon filter and converted into air having a high temperature by passing through a heater; supplying vapor heated to a specific temperature through a boiler (30) to the reaction tower (10) in which the active carbon filters are dried; sequentially supplying overheated vapor, generated by heating vapor through a heater (11) for each of the divided sections in the reaction tower (10) to each of the divided sections, to sequentially restore the active carbon filter inside of each of the divided sections; and supplying sewage and wastewater to the reaction tower (10) of which the restoration of the active carbon filters is complete so as to be purified, while blocking sewage and wastewater supply to the next reaction tower (10) so that a drying step is carried out with the air having the high temperature in each of the divided sections; and then sequentially supplying the overheated vapor to each of the sections to restore the active carbon filter filled therein, thereby purifying and circulating a large amount of water through the plurality of reaction towers (10) to enable sequential restoration of the active carbon filters.
