Scrubber Equipped with Diffraction Plate Generating Tornado Bubbles "

The present invention relates to a briquette scrubber which is a malodorous gas or a harmful gas purifier. More particularly, the present invention relates to a briquette scrubber having a baffle capable of generating a tornado bubble in a briquette scrubber to improve the cleaning performance of odor gas or noxious gas.

Types of air pollution control facilities used in industry today include dust collectors, adsorption towers, and scrubbers. Each of them is installed considering the efficiency depending on the kind of pollutants. Among them, scrubber is widely used because it has the advantage of treating dust, harmful gas and high temperature gas at the same time.

The scrubber is also called a gas absorption tower, which is divided into dry, wet and burnwet depending on the pollutant treatment method. A wet scrubber consists of a process in which a harmful gas is brought into contact with a liquid to dissolve the soluble component in the gas in the liquid phase. Wet scrubbers can be used for various purposes such as distillation and humidification because they can keep dust, mist and various air pollutants at the same time, Respectively.

Wet scrubbers typically use absorbent or cleaning fluids to make the removal of contaminants more efficient. The absorption liquid is used to remove contaminants through chemical reaction such as neutralization on the surface where the contaminants come into contact with the liquid, and various cleaning liquids including water are used.

The performance of the wet scrubber is determined by how efficiently the contact between the water containing the absorbent and the noxious gas can be achieved. Therefore, in the past, a method of using a filling material or providing a spray nozzle for supplying water with a small particle size so that the water containing the absorption liquid and the noxious gas can sufficiently contact with each other.
