Description

Waste gas treatment spray tower

Technical Field

The utility model belongs to the technical field of spray towers, and particularly relates to a waste gas treatment spray tower.

Background

The spray tower is used as a treatment device for treating environment-friendly waste gas, and when dust-containing waste gas or oil-containing waste gas passes through the spray tower body, a liquid medium is sprayed out from a proper position in the tower body, and alkali solution and sulfuric acid solution are used as some liquid medium. If the waste gas contains acidity, alkali liquor is selected to spray and neutralize the acidity, and if the waste gas contains alkalinity, sulfuric acid solution is selected to absorb. The specific choice of acid-base solution depends on the nature of the waste gas and the conditions of the enterprises. The waste gas containing oil and dust without acid and alkali can be sprayed and treated by circulating water solution. When the waste gas enters from the bottom of the tower body, the waste gas contacts with spraying media sprayed out of the spraying tower, the waste gas or oil stains are wrapped by water drops after contact, the collision surface area of the water drops wrapping pollutants is increased again, and the gravity is increased. Under the condition of increasing gravity, water drops wrapping pollutants fall into the bottom of the spray tower under the influence of gravity, heavier pollutants sink into the bottom of the tower body, and lighter pollutants float on the surface of the circulating water body.

For example, the patent with publication number CN214635352U discloses a spray tower for waste gas treatment, which comprises a spray tower, an air inlet pipe, an air outlet pipe and a packing layer, wherein one side of the bottom end of the spray tower is connected with the air inlet pipe, the top layer of the spray pipe is connected with the air outlet pipe, the packing layer is arranged on the top layer of the spray tower, a washing layer is arranged in the spray tower and is positioned above the washing layer, and a backwater treatment tank is arranged below the spray tower.
