This helps to break apart high molecular weight contaminants. A second cleaning action is carried out by the oxygen species created in the plasma (O 2 +, O 2 −, O 3, O, O +, O −, ionised ozone, metastable excited oxygen, and free electrons). [2] These species react with organic contaminants to form H 2 O, CO, CO 2, and lower molecular ...
Scrubber systems (e.g. chemical scrubbers, gas scrubbers) are a diverse group of air pollution control devices that can be used to remove some particulates and/or gases from industrial exhaust streams. An early application of a carbon dioxide scrubber was in the submarine the Ictíneo I, in 1859; a role for which they continue to be used today ...
A simple baffle scrubber system is shown in Figure 1. Liquid sprays capture pollutants and also remove collected particles from the baffles. Adding baffles slightly increases the pressure drop of the system. This type of technology is a part of the group of air pollution controls collectively referred to as wet scrubbers.
Figure 1-Centrifugal fan scrubber. Mechanically aided scrubbers are a form of pollution control technology. This type of technology is a part of the group of air pollution controls collectively referred to as wet scrubbers. In addition to using liquid sprays or the exhaust stream, scrubbing systems can use motors to supply energy.
Cyclonic scrubbers are generally low- to medium-energy devices, with pressure drops of 4 to 25 cm (1.5 to 10 in) of water. Commercially available designs include the irrigated cyclone scrubber and the cyclonic spray scrubber. In the irrigated cyclone (Figure 1), the inlet gas enters near the top of the scrubber into the water sprays. The gas is ...
An ozone monitor of this type operates by pulling an air sample from the atmosphere into the machine with an air pump. [3] During one cycle, the ozone monitor will take one air sample through the air inlet, and scrub the ozone from the air; for the next cycle, an air sample bypasses the scrubber and the ozone value calculated.
