<p>PURPOSE:To prevent the inflow of treated liquid together with the waste gas which is subjected to a wet oxidation treatment into a dry treatment tank by acting downward forcing pressure on the surface of the treated liquid in the treatment tank when the waste gas is separated from the treated liquid and emerges from the tank. CONSTITUTION:The air in a car tank is discharged through a suction and release pipe 1 through a suction-release selector cock 3 in the stage of sucking up from a vacuum car. The air passes a filter element 7 and is made thus free from oils, mists and solid filth. The malodorous waste gas cleaned by the filter enters the lower chamber of an automatic pressure regulator 8 and passes an outlet valve port 11b by forcing upward a valve disc 10. The gas flows in succession through the bubbling chamber 17 of a wet oxidation treatment tank 13, a gas-liquid sepn. and circulation chamber 18 and a static pressure chamber 19, then through the inside of a dry oxidation treatment tank 12, by which the gas is thoroughly deodorized. Th deodorized gas is discharged from a release pipe 37. The treated liquid entrained in the gas is separated by a collision plate 28, etc. during this time, and the waste gas ejected toward the surface 28 of the treated liquid in the chamber 19 through the blow-out port 30 of a blow-out pipe 29 applies downward forcing effect on the surface 25.</p> |
