Description

Technical Field

[0001] This utility model relates to the field of acid regeneration equipment technology, and more specifically, to a waste gas absorption tower for acid regeneration units. Background Technology

[0002] By spraying liquid onto the top of the waste gas absorption tower, the waste gas enters from the bottom of the tower, thus achieving mixing of liquid and gas. Acidic gases in the gas can be absorbed by the liquid to form regenerated acid for recycling, which can save production costs.

[0003] In existing technologies, by installing packing material inside the absorption tower and spraying liquid onto the packing material, a huge surface area can be provided, which greatly increases the gas-liquid contact area and thus significantly improves the treatment effect of the waste gas in the absorption tower. However, there are some problems in its use. In order to ensure the absorption effect of the packing material, the liquid needs to be evenly sprayed onto the packing material. In general devices, the liquid is discharged through the liquid outlet. More liquid is sprayed at the position below the liquid outlet, while less liquid is sprayed at the position on one side below the liquid outlet, which will affect the gas absorption efficiency.
