I.P. Scrubbers

Operating Principles :

The gas passes up through the openings in the perforated plates (Impingement Plate stage fixed on Diaphragm plate trays) which hold a bed of liquid.

The secret is in the Impingement plate scrubber’s design which uses an impingement baffle above each individual hole.

The tiny droplets, created by the wetted baffles, are the heart of the collection process.

High Gas velocities through the holes result in thousands of jets which atomize the liquid into droplets of the order of 100 microns in diameter to clean the contaminated gas. . Each jet aspirates liquid from the blanket of scrubbing fluid and results in a wetted target surface on the baffle which is located just above the point of maximum velocity (vena contracta). This entraps the particles in the scrubbing liquid.

Continuous violent agitation of the blanket of scrubbing fluid prevents settling of particles and flushes them away. Therefore In operation, the scrubber is highly pluggage-resistant. 

Intimate gas/liquid contact results in the maximum collection efficiency for particles and droplets as well as absorption (mass transfer) of gases and vapors. 

When used for absorption, low outlet emissions can be achieved by virtue of the scrubber’s countercurrent operation. 

The Bhavi Plast Impingement Plate Gas Scrubber is able to reduce gaseous pollutants to any desired concentration if a sufficient number of plate stages is used.

Benefits : 

High absorption efficiency for gases and vapors. Efficiencies of upto 98-99% are possible for removal of gaseous pollutants to any desired concentration if a sufficient number of plates are used. This means high mass transfer rates can be achieved.

98+% collection efficiency for particles 5 microns in size or larger.

These high particle collection efficiencies are achieved at a comparatively low pressure drop.
