[0001] APPARATUS FOR REMOVING BAD SMELL [0002]

The present invention relates to a malodor removing apparatus capable of multi-processing in order to effectively remove odor polluting gas.

As the industry develops and the abundance of life increases, the pollutants emitted are becoming diverse and increasing.

In such a situation, there is a need to regulate the production or treatment of pollutants all over the world, and various waste or pollutant treatment apparatuses are being developed accordingly.

However, the development of a malodor removing apparatus for removing odors generated from the above-mentioned waste or pollutants has not yet been developed.

Conventional malodor treatment apparatuses employ an adsorption method, a cleaning method, or a combustion method.

Specifically, the above-mentioned adsorption method uses activated carbon or the like, which can not effectively remove odors, and has a disadvantage of requiring secondary treatment of the adsorbent.

The cleaning method has a disadvantage in that the contact area between the liquid and the contaminated gas is small and the efficiency of the flow of the polluted gas to avoid contact with the liquid is poor, .

The combustion method is effective in an environment with a low wind and a high concentration of polluting gas, but it has a disadvantage of high equipment cost and combustion cost.

In addition, since the polluted gas may contain a basic, acidic or heavy reducing gas, a malodor removing device capable of effectively removing such a complex pollutant gas is needed.

It is an object of the present invention to provide a malodor removing apparatus capable of effectively removing polluted gas.

And a first nozzle unit disposed inside the first duct to jet the liquid introduced from the wastewater treatment unit.

The second gas discharging unit may include a second duct having one side communicated with the gas outlet formed on the upper side of the second chamber and the other side disposed in the second chamber with a predetermined distance from the alkaline solution; And a second nozzle unit disposed inside the second duct for spraying the liquid introduced from the wastewater treatment unit.

The contaminated gas supply unit may include an inlet duct through which the polluted gas flows; An exhaust fan disposed in the inflow duct to flow the polluted gas; And a supply pipe communicating with the inflow duct and supplying the contaminated gas into the acidic liquid of the first chamber or the alkaline solution of the second chamber.
