Rotary-type heat exchanger

Abstract

A rotary-type heat exchanger comprises a rotor having gas passages in the direction of its shaft, a casing for said rotor, an entrance of said casing to guide the high temperature incoming gas to be used for the heat exchange exclusively toward said rotor except for the gas passages outer periphery thereof and the areas close to the shaft of said rotor, a heat insulation being treated on the inner wall of said entrance, a sealing member for high temperature being provided on the entrance toward said rotor to keep the gas leakage minimum, an exhaust gas outlet of said casing being provided on the side opposing to said entrance to guide all the exhaust gas passed through said rotor to outside, a sealing member being provided on the exhaust gas outlet toward said rotor of said exhaust gas outlet to keep the gas leakage minimum, an outer fresh gas inlet of said casing to guide outer fresh gas into said casing, for heat exchange and cooling an outlet port of said casing being provided on the side opposing to said outer fresh gas inlet to guide the heated gas from said rotor to outside, and a heat insulation being treated on the inner wall of said heated outer gas outlet port.
