MDSJ Clean Air Technology dynamic wet fan scrubber is preferred in all industrial applications where dust, aerosol and gas are present, especially in the metal and chemical industries. It can also be used for dust control and odor control in spray dryers and solid waste incineration plants. Dynamic scrubbers are manufactured as a single stage between 3000m3/h and 100000m3/h, although 316L stainless material is generally preferred, carbon steel material is also used.
How Does Dynamic Scrubber Work?
The dust-laden gas enters the lower chamber of the scrubber tangentially, giving the flow a cyclonic effect. Coarse particles are removed by a combination of centrifugal and gravitational forces. The flow encounters the dirty water slurry formed in a later stage, descending from the upper chamber, and is partially wetted, resulting in a second-stage cleaning.As the flow rotates through a series of scrubber blades, medium-sized particles strike the wetted surfaces of the blades. These particles are then washed away. The remaining gas stream containing fine dust is drawn into an adjacent chamber. Atomized spray liquid is sprayed into the fan eye, further reducing the droplet size. These droplets encapsulate the fine dust particles, thus increasing cleaning efficiency.The gas stream then flows tangentially at high velocity into the upper chamber. The wet agglomerated particles are partially attached to the chamber walls by cyclonic action and flow downward and into the inner discharge cone. The gas stream, free of liquid droplets, passes through an eliminator at the top of the scrubber where the droplets are retained and the clean gas is discharged to the atmosphere through the outlet.
