Air washing by drying systems

lucht reiniger ammoniak

Air washing is applied with dryers for the purpose of cleaning the air after the drying process. The air washer removes undesirable ammonia, dust and odours from the air.

The principle of chemical air washing is that ammonia leads to a chemical reaction when it comes into contact with sulphuric acid, causing the ammonia to combine with the sulphuric acid to generate the neutral ammonium sulphate. In the air washer, the ammonia in the air is brought into contact with sulphuric acid in an efficient manner.

A water curtain is used for removing dust. The air is sucked through a blanket of spray water, whereby the dust remains in the water.

How the Dorset Air Washer works is described in the section ‘Air Washers’.
