Efficient acid vapour treatment for laboratory and industrial applications. FRIDURIT acid absorption units ensure environmentally friendly and standard-compliant removal of harmful gases such as perchloric acid, hydrogen fluoride, sulphuric acid and hydrochloric acid. Energy-saving, reliable air pollution control for clean air.
Efficient treatment of fumes for laboratories and industrial applicationsIndustrial and laboratory processes often emit harmful air pollutants that are subject to strict legal requirements. Compliance with regulations such as the Air Quality Control and Emissions Control Act is essential to meet environmental requirements and minimise health risks. High-performance anaerobic digestion units ensure efficient cleaning of chemically contaminated used air directly at the source of the emission and offer an economical solution for your company.
are specifically designed to remove aggressive and toxic gases and offer a number of advantages:
Exhaust air washer with spray wheel system
In the case of exhaust air scrubbing with a spray wheel system, the polluted gas stream is directed to the absorption chamber of the exhaust air scrubber.
The spray wheel sucks in the unloaded washing liquid and atomizes it. The spraying of the washing liquid causes the droplets of washing liquid to become smaller, resulting in an increase in the surface area of each droplet. This surface is also the contact surface between the pollutant from the gas stream and the washing liquid, where absorption, i.e. the binding of the pollutant from the gas stream to the washing liquid, takes place. This increased contact area thus allows for more efficient absorption of the pollutant.
Since the rising gas stream can carry droplets of contaminated washer fluid, droplet separators are located in the exhaust air scrubber. Individual droplets collect on these, clump together and drip back into the absorption chamber.
The exhaust air, now cleaned, is then removed from the exhaust air washer, leaving the dirty washer fluid in the washer.
The contact time between the gas stream and the washing liquid is usually short, so a faster wash is possible than with a column.
