Description

Technical Field

[0001] This utility model belongs to the field of chemical waste gas purification technology, specifically relating to a vertical PP spray tower for chemical waste gas purification. Background Technology

[0002] Vertical PP spray towers are widely used in industrial waste gas treatment. "Vertical" means that the spray tower is in an upright position when it is working, which is different from horizontal spray towers. "PP" means that the spray tower is made of polypropylene (PP) material.

[0003] The vertical PP spray tower mainly consists of a tower body, a liquid storage tank, an air inlet section, a spray layer, a packing layer, a cyclone demister layer, a viewing window, and an air outlet. The tower body is usually cylindrical and connected in sections by flanges. During operation, the exhaust gas enters the packing absorption layer from the bottom of the tower body under the power of the fan. The pollutants in the gas come into contact with the liquid medium on the packing and undergo a chemical reaction. The exhaust gas or oil is wrapped by water. The water droplets that wrap the pollutants collide with each other, increasing their surface area and gravity. Under the influence of gravity, the water droplets that wrap the pollutants fall into the liquid storage tank at the bottom of the spray tower. Heavier pollutants sink to the bottom of the tower body, while lighter pollutants float on the surface of the circulating water. The gas that is not completely absorbed continues to rise to the spray section and continues to react chemically with the liquid medium sprayed by the high-speed nozzles. The absorbent liquid droplets carried in the gas are removed in the demister layer equipped with a demister device. The treated clean air is discharged from the exhaust pipe at the top of the purification tower.

[0004] In the existing technology, the filler absorption layer is usually inspected and the filler is replaced through a visual inspection window. Although this can meet general usage needs, the limited opening size of the visual inspection window makes the work of replacing the filler inconvenient.
