Dry media and scrubbers or wet collectors are two distinct technologies designed to collect dust produced during production processes. Syntech shares that both kinds of dust collectors come with their pros and cons.
Wet Dust Collectors
Wet dust collection involves the use of centrifugal kind or cyclonic scrubbers or Venture scrubbers that function on different standards compared to dry cartridge collectors. Scrubbers collect dust by combining with water droplets. The scrubber becomes more efficient as the droplets get smaller.
The design of this equipment may integrate one or more of the methods to gather dust. This includes wet impingement configurations, spray nozzles, cyclonic action, Venturi dispersion and misters. As soon as it is collected, both dust and water drip into the settling tank where gravity separates them or where it skims dust from the surface.
For instance, dust-filled air goes into the scrubber indirectly and centrifugal forces then thrust the material to the outer wall, similar to how a cyclone works. The captured material then rests at the bottom of the sludge tank.
Dry Dust Collection
The National Fire Protection Association (NFPA) describes dust collectors as media and cyclone collectors, cartridge collectors and baghouses. Cartridge dust collectors are highly efficient, and these dry media kind of collectors are broadly used for the fine material dust produced in processing applications.
When dusty air goes in the collector, filter media captures it. Intermittent gusts of compressed air then remove the dust from the filters and transfer them into the hopper. Afterward, the dust is dislodged from the hopper before it moves into a detached container or storage drum that users must regularly empty. This prevents the dust from going back into the hopper.
Now that you are aware of the differences between wet and dry collectors, and their pros and cons, you can decide which is suitable for you.
