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 ...
Another mechanically aided scrubber, the induced-spray, consists of a whirling rotor submerged in a pool of liquid. The whirling rotor produces a fine droplet spray. By moving the process gas through the spray, particles and gaseous pollutants can subsequently be collected. Figure 2 shows an induced-spray scrubber that uses a vertical-spray rotor.
Mason, a tradesperson skilled variously in brick and blocklaying, concrete finishing (the placement, finishing, protecting and repairing of concrete in construction projects). [7] Also stonemason, marble setter and polisher, tile setter and polisher, terrazzo worker and finisher. Hod carrier is a subsidiary trade (also see Laborer).
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.
Depending on scrubber design, a minimum volume of liquid is required to "wet" the scrubber internals and create sufficient collection targets. After a certain optimum point, adding excess liquid to a particulate wet scrubber does not increase efficiency and in fact, could be counter-productive by causing excessive pressure loss. Liquid-to-gas ...
The term wet scrubber describes a variety of devices that remove pollutants from a furnace flue gas or from other gas streams. In a wet scrubber, the polluted gas stream is brought into contact with the scrubbing liquid, by spraying it with the liquid, by forcing it through a pool of liquid, or by some other contact method, so as to remove the ...
A venturi scrubber is designed to effectively use the energy from a high-velocity inlet gas stream to atomize the liquid being used to scrub the gas stream. This type of technology is a part of the group of air pollution controls collectively referred to as wet scrubbers .
A scrubber (German: Schrubber), is a type of wide brush with a long shaft used for cleaning hard floors or surfaces. Unlike a broom , which has soft bristles to sweep dirt away, a scrubber has hard bristles for brushing.
