We Dynavac are the leading manufacturer of venturi Wet scrubber in India for various industrial Process applications and also where there are a chance of sparking dust catching fire or creating an explosion. Dynavac Venturi Wet Scrubbers are tailor-made as per the customer's process application to capture the Dust particles, Chemical Fumes, High-temperature fumes, VOCs, etc., The major part in designing Venturi scrubber for any particular process application is Machine Size, Machine Design, Scrubbing liquid, Material of Construction.
Venturi scrubber works on the principle of the absorption and venturi effect, where the dirty gas and scrubbing liquid (In general, water is mainly used as a scrubbing liquid for quenching or scrubbing the particles) is made to pass through a confined throat of the venturi where both come in contact so closely and forms a large number of droplets, thereby creating a large area for the dust particles to get absorbed to liquid droplets.
A typical Venturi Scrubber system incorporates, A scrubbing Chamber with a Venturi throat to facilitate particle collection. A centrifugal fan, Recirculating pump, Jet Flow Spraying System, Mist eliminator pad, and Exhaust Chimney.
A venturi scrubber consists of two chambers:
The First Chamber is a Venturi and It consists of three sections: a convergent section with a Jet flow spray nozzle, a throat section, and a divergent section.
The Second Chamber is a Scrubbing Chamber and It Consists of two Sections: An Empty Cylindrical Scrubbing Chamber with a Jet flow Spray Nozzle and Mist Eliminator Pads
The dirty gases/air are passed through the inlet of the Venturi in a vertical direction through the convergent section. Whereas, water containing the washed-away particles and dissolved gases finds an outlet at the bottom of the divergent section.
The liquid will be sprayed by a high-speed jet flow spray nozzle at the intersecting point of the venturi. Then the liquid splatters inside the venturi chamber very effective for handling dust.
Then the partially scrubbed polluted gases are then passed into the Second Chamber through a tangential inlet to create a Cyclone effect.
The liquid is injected into the top neck of the cylinder in this chamber.
Due to the Cyclonic Effect and High Pressurized liquid injection further Particle and gas removal happens here.
The slurry is removed from the bottom of the scrubbing chamber.
The water is again recirculated into the chamber.
Scrubbed gases are passed out through the mist eliminator pad to eliminate carrying-over liquid particles.
