METHOD AND DEVICE FOR REDUCING TEMPERATURE OF EXHAUST GAS UTILIZING HOT WATER

摘要

It is the principal object of the present invention to provide a system for temperature reduction of exhaust gas in an incinerator or boiler equipment having an exceedingly small size and avoiding any difficulties caused by damages on the wall surface of a gas cooling chamber due to adherence of sprayed washer droplets and deposition of dust. More specifically, pressurised thermal water with the temperature higher than a boiling point of water under atmospheric pressure is sprayed as temperature reduction water into high temperature exhaust gas Gh in a gas cooling chamber or an exhaust gas duct. The temperature reduction of exhaust gas and the removal of said gas in exhaust gas are simultaneously achieved by spraying pressurised thermal water At containing alkaline solution as temperature reduction water into high temperature exhaust gas Gh in the gas cooling chamber or the exhaust gas duct.
