The water purifier is filled with a certain amount of liquid in the vacuum chamber and forms a large amount of droplets, liquid film, And may be S type, impeller type, rotor type, fraction type, spiral guide type, and the like.

On the other hand, the pressure-modulated vibration damping apparatus is a method of cleaning the contaminated gas by pressurizing and supplying the cleaning liquid, such as a venturi scrubber, a jet scrubber, a cyclone scrubber, The vibration damping device uses a rotation of the blower to form a droplet, a water film, and a bubble to clean the disk. The disk is a washer, an impulse scrubber, or the like.

There are a number of prior art based on the above-mentioned pollutant gas purifying apparatuses, in which the contact area between the cleaning liquid and the polluted gas is increased to improve the vibration damping efficiency.

Korean Patent No. 10-0451533, entitled "Pollution Gas Purification Device" (Patent Document 1), is a registered patent of the present inventor, which comprises an air inlet through which air contaminated by a blower flows; An internal water collecting tank having a plurality of air discharge pipes formed between the inner passage auxiliary water tanks and the auxiliary water tank at the center of the inner tube to form an outer tube so as to form a hollow portion at a predetermined interval on the inner tube outer peripheral surface; A filling layer and an upper partial tube formed on the inner water collecting tank and regulating the contaminated air which is firstly cleaned; An exhaust port for discharging cleaned air to the atmosphere; And the other side connected to the auxiliary water tank is closed so that the contaminated air and the cleaning liquid are in contact with each other and the cleaning liquid is contacted with the cleaning liquid, A long hole is formed in the longitudinal direction so as to be able to be blown out in a state where the air inlet is formed, and a shielding film is formed on the hollow portion in which the air inlet is formed.

However, in the case of Patent Document 1, there is a problem that the initial cleaning efficiency for contaminated air is lowered as the air introduced through the air inlet flows directly into the inner collecting tank through the air discharge pipe.

In addition, since the air introduced into the inner collecting tank via the air spouting tube simply contacts the cleaning liquid, it is necessary to increase the contact area and contact time with the cleaning liquid in order to improve the cleaning efficiency.

In addition, there is a problem that the cleaning efficiency is lowered by blocking the injection nozzle in the process of circulating the foreign matter through the auxiliary water tank.

In addition, when suspended solids or oil mixed in the contaminated air flows, a film is formed on the surface of the inner collecting tank, thereby blocking the movement of the cleaned air, thereby deteriorating the cleaning efficiency.
