PURPOSE: To provide a compact gas purifier with high purifying efficiency by mixing fresh air with contaminated gas, passing the mixed gas through a septic tank, and releasing a part thereof to the air after deodorizing from an air blasting mechanism and using the remainder as ventilating gas to the septic tank. CONSTITUTION: Contaminated gas after passing through a septic tank 7 is mixed with fresh air from the entering side 8. By an air blasting mechanism 3, a part of the gaseous mixture is passed through a deodorizing mechanism 6 from a valve 5a and then it is released in the air from the leaving side 9. By the mechanism 3, the remainder thereof is again led to the septic tank 7 from a valve 5b and used as ventilating gas. Thus, the mechanism 3 is shared between the deodorizing mechanism 6 and the tank 7. Since contaminated gas is further mixed with fresh air, humidity is reduced and there is not much danger of equipment corrosion and the life of a catalyst is prolonged. |
