Spray scrubber

The spray scrubber is often used for process waste gases whose temperature and/or dust load is too high to be cooled and cleaned in a column scrubber. The other pollutants contained in the process are removed by a reagent using a dosing pump in the water circulation system.

The system is subject to certain limits with regard to its cleaning performance, as the retention time within the system and the distribution do not come close to that of a column scrubber.

In the presence of high temperatures and dust loads, this type of scrubber is often installed upstream of a column scrubber.

The injection system is located in the head area of the jet scrubber and a receiver tank is located in the base area, which collects the injected liquid. A circulation pump conveys the liquid to the injection point. A dosing pump doses the appropriate reagent into the circulating water on the way to the injection point. The exhaust gas inlet is located at the top of the spray scrubber and the outlet in the lower area of the cylinder.
