<p>PURPOSE: To allow only the purified gas to rise above a purifying soln. and to be discharged by injecting the purifying soln. into a cylindrical water tank to form a vortex and injecting pollutant gas in the same direction as the direction of the vortex. CONSTITUTION: The pollutant gas sucked by a suction fan is forcibly fed to an annular gas feed tube 2 and the cylindrical water tank 3 is erected in the gas feed tube 2. Many nozzles 5 are unidirectionally formed at many connecting tubes 4 radially installed therein to directly communicate the connecting tubes 4 and the air feed tube 2. Many water tubes 6 are erected in the water tank 3 and many nozzles 7 are arrayed on a vertical line unidirectionally. A pump P1 is connected to the many water tubes 6 and an auxiliary water tank 8 is installed at the center of the water tank 3. A solenoid valve 10 actuated by a bell probe 9 is connected to the lower side thereof. Consequently, the gaseous contaminant material react with the water and are dissolved. Only the harmless gases, such as CO2 , N2 and O2 , are eventually discharged.</p> |
