Point-of-Use Waste Gas Scrubber SALIX (wet)
SALIX is our new wet scrubber family specialised on process waste gases from wet benches. SALIX makes part of DAS Environmental Expert´s Point-of-Use Waste Gas Treatment Portfolio. In one or two scrubber stages process pollutants are removed from the gas stream by chemical and physical absorption. In the scrubbing process the waste gases are passed through the scrubber stages with different washing liquids. Access for operating and maintenance is from the front and right side, alternatively from the back side.
Operating Principle of the Wet Scrubber System SALIX
The waste gases are fed by up to twelve separate inlets into pre-scrubber using spray nozzles which eliminates any clogging at the input.
The waste gases pass into the first scrubber stage and flow upwards through the first scrubber column filled with packing material. The column is supplied with the scrubbing liquid via spray nozzles. Due to the large surface of the packing material and the counter flow principle the optimal absorption of the waste gases is possible.
In the second stage a different scrubbing liquid is used. A demister is used to prevent the liquids from the two stages from mixing. The second scrubbing liquid allows an alternative chemistry to be used and so optimise the scrubbing of the waste gases. Ingredients of waste gases, which have not reacted in the first scrubber stage, can be better absorbed in the second scrubber stage. After the deposition of residual moisture of the gas flow in a demister the residual gases meet the strict standards of German air pollution law (TA Luft).
