Product Description:
The WEV Scrubber is a pressure drop-driven wet scrubber which uses a unique principle to achieve high scrubbing efficiency of particulates and acid gases. It uses energy more efficiently than conventional scrubbers, with the majority of applications requiring less than 10" wg pressure drop. It is adjustable to suit changes in gas flow or scrubbing efficiency. The WEV Scrubber has better performance characteristics than the venturi.

Performance Calculations:
To calculate the scrubber operating data to meet the emission specification, we require the process data listed in the scrubber Inquiry Sheet (available upon request). It is particularly important to define the pollutants and, in the case of particulates, to provide the particulate size distribution (PSD) with at least 5 data points. This is necessary for checking:

For particulate scrubbers, the pressure drop is determined by a pressure drop computation program (using the PSD). The performance of the WEV Scrubber is superior to that of the Venturi.

Typical Applications:
Particulate Scrubbing: - Dryer exhausts; - Food Products
                                    - Biomass Boiler - Mineral Processing

Particulate + Absorption: - Boiler (coal)
                                        - Pulp mill (smelt tank)
Absorption: - Pulp mill (bleachery)

We Supply:
WEV Scrubber complete with all necessary accessories, coupled with system fan and stacks for rain-out types.

Principle of Operation:
The scrubbing liquid is introduced into the droplet generator (Atomizer) and is sheared into droplets by the high velocity spin action induced in the gas by passing through a stationary vane assembly built into a cyclonic housing. The liquid is sheared into droplets, some of which flush the walls of the cyclonic housing, while the balance form a dynamic rotating droplet cloud through which all the gas and pollutants must pass.
The inlet gas is thus treated to 3 types of contacting in the same housing:

The spent scrub liquid drains to the bottom of the scrubber. The balance, as entrained mist, is separated in the high efficiency mist eliminator above. See Fiqure below.
