Title:
EXHAUST GAS SCRUBBING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/100190
Kind Code:
A1
Abstract:
Provided is a heat-storage-type exhaust gas scrubbing device that is capable of efficiently pyrolyzing toxic components, especially persistent components such as PFCs that decompose at high temperatures, in exhaust gas with less fuel expenditure, regardless of heat source type. Specifically, thermal energy storage elements (16) are disposed so that the central axes thereof in the gas flow direction are arranged on concentric circles, and a heat source (24) is disposed at a position on a ceiling of a combustion chamber (22), said position corresponding to the center of the concentric circles. The gas flow path in heat storage chambers (18) is controlled so that there are multiple exhaust-side chambers per intake-side chamber leading to the combustion chamber (22). In addition, the inner surface of the combustion chamber (22) is formed so that the gas flow path therein is symmetrical within the concentric circles as seen in a plan view.
