Title: Method and apparatus for removing dusts of combustion exhaust gas in toxic exhaust gas combustion processing device
Inventor: HASHIMOTO HIDEO
IPC: F23J15/04
Filed: 1989-11-17
Abstract: PURPOSE:To cool combustion exhaust gas and enable a dust removal to be carried out without producing any variation in pressure within a combustion furnace by a method wherein a jet scrubber having a gas suction inlet applied as a releasing end is stored in a combustion processing device. CONSTITUTION:Pressurized water flow enters from a line 29 into a main body 30 of a jet scrubber vertically arranged in a combustion processing device 3 and the water flow is injected at a high speed through a spray nozzle 33. With such an arrangement, combustion exhaust gas G is sucked from a gas suction inlet 35. Gas and liquid are mixed at a diffuser 34 so as to perform a cooling of combustion exhaust gas and a dust removing operation. The discharged liquid-gas mixture strikes against a buffle plate 32, resulting in that only liquid drops to a bottom part and is discharged from a line 15. The cooled and dust removed combustion exhaust gas ascends at a cover part 31, sucked again from the gas suction inlet 35, dust is removed from the mixture. A part of it is liquid droplets separated at a mist separator 36 and after this operation the separated substance is discharged from a line 13. This jet scrubber has a releasing end acting as a gas suction inlet to cause the combustion exhaust gas to be sucked and further the gas once dust removed is sucked and then an amount of suction of the gas is always kept constant and so no variation in pressure occurs.
