Text Box: Venturi Scrubber EnviroAir can provide a venturi scrubber to remove tissue dust from the exhaust air. Our venturi scrubber has a wetted wall venturi eliminating the wet/dry interface region where buildup often occurs.  The dust-laden air and water are accelerated in the converging section of the venturi. The water is atomized In the venturi throat and the dust particles collide with and are absorbed by the water droplets. The exhaust air and dust-laden water droplets enter the cyclonic separator through a tangential inlet.  The tangential inlet causes the flow to spin through the separator towards the top discharge.  The heavy dust-laden water droplets are thrown to the separator wall by centrifugal force where they collect and coalesce.  This liquid slurry runs down the separator wall to the bottom drain or integral recirculation tank.  The clean exhaust air is discharged out the top of the separator. The venturi scrubber shown at left is removing dust from 38,000-cfm of air exhausted from a paper machine. Text Box: Low Profile Venturi Scrubber The venturi scrubber shown at right is our low profile design. Instead of a cyclonic separator, this design uses a series of chevron mist eliminators to remove the dust laden water droplets from the airstream. This scrubber design permits locating the scrubber in low head room areas. This low profile design will be slightly more expensive and will require more maintenance than a venturi scrubber with cyclonic separator. This venturi scrubber at right is removing dust from 46,000-cfm of air exhausted from a paper machine.

A baghouse is often used when the customer wishes to return the exhaust air to the building to reduce energy costs. Each baghouse is designed in accordance with NFPA 68 and is furnished with membrane style explosion relief vents. Each baghouse is furnished with fire protection that includes a 3-tier fire sprinkler system with quick-response, sidewall type sprinkler heads and relief valves in the hopper to dump water if the sprinkler system is activated. The baghouse shown at left is removing dust from 45,000-cfm of air exhausted from two converting rewinders.
