HOW
IT WORKS
High collection efficiency, in excess of 98% in the 1 to 2 micron range is achieved by use of the wet type fan. The wet fan mixes gas, dust and water by extreme turbulence, forcing the fine dust particles into the scrubbing liquid. The result is a combination of exceptionally high efficiency with low power requirements.
It is a multi-stage system. Gas entering the lower portion is immediately saturated and the larger particles washed out by the unique wet approach venturi. The gas leaving the lower section makes a 180 degree turn, forcing out excess moisture and causing particle impingement on the wetter lower cone surfaces. Gas is drawn up through the agglomerator chamber into the fan inlet. Water is again added as the gas is pulled through the fan and discharged at high velocity into the eliminator chamber. Free moisture is spun out and the cleaned air sent up through the vertical outlet. The fan, a rugged, heavy duty open paddle wheel assembly is sized and powered to fit both the scrubber and the system, eliminating the need for an additional fan. Problems of build-up are minimised by having the fan thoroughly wet at all times.
The fan operates at a constant speed, delivering top performance even when the gas flow is as low as 60% of the design volume.
For economy, liquids can be recycled to the lower spray header of the standard Type R. Fresh water or low solids content scrubbing liquid is recommended for the fan inlet spray to minimise abrasion. Type R is available in twelve sizes, covering a wide range of air volumes.
EQUIPMENT SPECIFICATIONS
The Type R Scrubber, of cylindrical shape, shall be of the high efficiency wet approach peripheral nozzle type with radial inlet from which the gases to be cleaned are jetted in a near vertical downward direction through a wet approach low energy venturi before making a 180 degree turn to the wetted fan inlet. The dynamic fan discharges tangentially into a high velocity centrifugal water elimination chamber. Gases exit through a top vertical discharge.
