EXHAUST GAS TREATMENT SYSTEM AND EXHAUST GAS TREATMENT METHOD

摘要

[PROBLEM] IT IS AN OBJECT TO PROVIDE AN EXHAUST GAS TREATMENT SYSTEM (10, 100, 200, 300, 400) AND AN EXHAUST GAS TREATMENT METHOD CAPABLE OF REDUCING THE AMOUNT OF MAKEUP WATER GIVEN TO DESULFURIZATION MEANS (40) AND REDUCING THE HEAT SOURCE REQUIRED BY DESALINATION MEANS (80). [SOLUTION] AN EXHAUST GAS TREATMENT SYSTEM (10, 100, 200, 300, 400) OF THE PRESENT INVENTION INCLUDES WET DESULFURIZATION MEANS (40) FOR REMOVING A SULFUR OXIDE IN AN EXHAUST GAS, DESALINATION MEANS (80) FOR PRODUCING FRESHWATER FROM SEAWATER AND SUPPLYING THE FRESHWATER TO THE WET DESULFURIZATION MEANS (40), A HEAT EXCHANGER (20, 20A, 20B) FOR HEATING A HEAT MEDIUM WITH THE EXHAUST GAS AT A STAGE BEFORE THE WET DESULFURIZATION MEANS (40), A SEAWATER HEATING DEVICE (22) OF THE DESALINATION MEANS (80), AND A CIRCULATION LINE (24) FOR CONNECTING THE HEAT EXCHANGER (20, 20A, 20B) WITH THE SEAWATER HEATING DEVICE (22) AND CIRCULATING THE HEAT MEDIUM.
