Venturi scrubbers are used to remove particulate matter from a gas stream. A „Venturi Scrubber“ consist of a contact section called a venturi section in combination with a droplet separator section.
Exhaust gas with dust is fed into the venturi section where it passes through a water mist at the venturi throat at high velocity. This results in thorough mixing of water droplets and dust particles which agglomerate to form larger particles which are subsequently removed from the gas in the separator section.
The water supply units and spraying systems allow recirculation of water with high dust contents. These systems are used for cleaning particulate matter from exhaust gas with stringent emission level, soluble dust mainly in the mineral and chemical industry.
