EXHAUST GAS TREATMENT DEVICE FOR ORGANIC COMPOUND DECOMPOSITION TREATMENT FACILITY

摘要

PROBLEM TO BE SOLVED: To appropriately maintain the internal pressure of a thermal decomposition furnace and to prevent back fire from a combustor in an exhaust gas treatment device for an organic compound decomposition treatment facility wherein exhaust gas produced by the thermal decomposition of an organic compound in a thermal decomposition furnace is burnt in the combustor. SOLUTION: The exhaust gas from the thermal decomposition furnace 1 is sucked by an ejector 3 using water as a driving fluid. On the basis of a detection signal of a pressure detector 26 for detecting the internal pressure of the furnace, the rotating speed of a water pump 20 for supplying the driving fluid to the ejector 3 is changed to adjust the suction quantity of gas, thus maintaining the internal pressure of the furnace within a fixed range. The exhaust gas is exhausted together with the driving fluid (water) of the ejector 3 to the combustor 5 side to prevent back fire from the gas combustor 5. COPYRIGHT: (C)2003,JPO
