Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification, in particular to a waste gas purification spray device. Background Art

[0002] At present, in daily life, waste gas treatment is also called waste gas purification. Waste gas treatment refers to the pretreatment of waste gas generated in industrial sites and factory workshops before it is discharged. General waste gas treatment includes organic waste gas treatment, dust waste gas treatment, acid-base waste gas treatment, odor waste gas treatment and air sterilization and purification. The existing technology of spray filtration waste gas purification device is troublesome and unsafe to handle manually.

[0003] Among them, the spray tower is a common equipment for treating waste gas. When the dust-containing waste gas or oil-containing waste gas passes through the spray tower body, liquid medium is sprayed out from the appropriate position inside the tower body (depending on the design). Some are alkali solution and some are sulfuric acid solution. If the waste gas contains acid, alkali solution spraying is selected to neutralize the acid. If the waste gas contains alkaline, sulfuric acid solution is selected to absorb it. The specific selection of acid and alkali solution depends on the nature of the waste gas and the company's own situation. Waste gas without acid or alkali but containing oil and dust can be treated by spraying with circulating water solution. When the waste gas enters from the bottom of the tower body, it comes into contact with the spray medium sprayed from the spray tower. After contact, the waste gas or oil is wrapped by water droplets. The water droplets wrapped with pollutants collide again, the surface area increases and the gravity increases. When the gravity increases, the water droplets wrapped with pollutants fall to the bottom of the spray tower under the influence of gravity. The heavier pollutants sink to the bottom of the tower body, and the lighter pollutants float on the surface of the circulating water body.

[0004] However, most of the spray towers on the market spray purified water through the spray plate to spray the imported waste gas for purification. This operation is not easy to make the waste gas completely contact with the purified water, resulting in insufficient waste gas purification. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content
