HEAT RECOVERY DEVICE OF EXHAUST GAS AND EXHAUST GAS TREATMENT SYSTEM USING THE SAME |
摘要 |
<p>PROBLEM TO BE SOLVED: To provide a heat recovery device of an exhaust gas where heat recovery from the exhaust gas can be efficiently achieved from a high temperature region to a low temperature region and exhaust gas treatment corresponding to the acid dew point of the exhaust gas can be performed.SOLUTION: In a heat recovery device of an exhaust gas having a first cooling unit 1, a desulfurization treatment unit 2, a dust removal treatment unit 3 and a second cooling unit 4: dust removal treatment is achieved by using a heat-resistant filter medium 3a in the dust removal treatment unit 3; cooling treatment is achieved so that the temperature of a second exhaust gas G2 is an acid dew point or higher and the heat-resistant temperature of the filter medium 3a or lower in the first cooling unit 1; cooling treatment is achieved so that the surface temperature of a ceramic pipe 4n is the acid dew point of a third exhaust gas G3 or lower using the ceramic pipe 4n whose main component is SiC in the second cooling unit 4; and the third exhaust gas G3 is heat-exchanged with a heat medium M supplied to the inside of the ceramic pipe 4n and the warm heat of the heated heat medium M is recovered.</p> |
