Title:
SYSTEM FOR DRYING SLUDGE REHEATED BY CIRCULATED STEAM
Document Type and Number:
WIPO Patent Application WO/2019/088399
Kind Code:
A1
Abstract:
A system for drying sludge reheated by circulated steam according to the present invention includes: a dryer which receives a sludge and dries the moisture of the sludge by means of a heat source, thereby forming a dry sludge material; a deodorizing furnace which receives a dry distilled gas, which is generated in the dryer, through a transfer line, and burns the dry distilled gas, thereby removing the moisture and odorous ingredients contained in the dry distilled gas; a steam heater which uses the deodorized gas discharged from the deodorizing furnace to heat the dry distilled gas supplied through a circulation line branched from the transfer line through heat-exchange, and supplies the heated dry distilled gas to the dryer as a heat source; an exhaust fan installed on the transfer line and controlled by an automatic damper according to the downstream pressure of the dryer to supply the dry distilled gas to the deodorizing furnace; and a circulation fan installed on the circulation line and supplying to the steam heater, the remaining dry distilled gas in the transfer line from which an amount, corresponding to the moisture evaporated in the exhaust fan, of the dry distilled gas has been removed.
