What are Venturi or Particulate Scrubbers?

Venturi Scrubbers, also known as Particulate Scrubbers, are air control systems that are highly efficient at removing particulate matter (PM) emissions from industrial exhaust generated from both batch and continuous type process applications.

Venturi Scrubbers have several advantages compared to filters and other dust collection equipment. One advantage is that they can handle particle-laden gas streams that contain moisture and/or are high temperature. Another advantage is that the overall size of the equipment is often smaller.

A typical Venturi Scrubber system incorporates a scrubbing vessel with a Venturi throat to facilitate particle collection. Other system components include a system fan, recycle pump, instrumentation and controls, mist eliminator, and exhaust stack.

Venturi Scrubbers remove PM from dirty exhaust streams by collecting the particulates in liquid droplets. Particle-laden exhaust gas enters the scrubber where it is forced into contact with the scrubbing fluid. The liquid containing particulates is separated from the gas by gravity and downstream mist eliminator section. Removal efficiency is typically in excess of 99%.

     

What is a Multi-Vane Venturi Scrubber?

A Multi-Vane Venturi Scrubber system is a high-efficiency Venturi-type scrubber which forces the dirty exhaust air through multiple vanes. These muliple vanes make the system perform as if it were multiple Venturi Scrubbers.  These internal vanes are engineered for specific particulate removal efficiencies as a function of particle size (PM 10 or PM 2.5) and pressure drop.  Multi-Vane Venturi Scrubbers offer higher removal efficiencies using less energy. Other than a system fan and recirculation pump, the equipment is solid state. They are also inherently self-cleaning and therefore simple to maintain.

How Does a Multi-Vane Venturi Scrubber Work?

High velocity, dirty particle-laden air enters the scrubber’s Multi-Vane section at the same time recycled scrubbing fluid is injected into the same area. The force of the air shears the fluid into tiny droplets, forming a cloud. The cloud is subjected to vortex action which forces the particulates from the air, entraining it into the droplets. The force applied, along with gravity, separates the dirty droplets from the particle-free air.  The dirty droplets gather on the scrubber walls and then fall (like rain) into the sump, where some goes for wastewater treatment and the rest is mixed with clean water and recycled. The clean air goes out through the stack.

 

Particulate Scrubber Applications

Pollution Systems’ top quality Venturi Scrubbers maintain high on-stream performance. Some of the more common industrial applications of Venturi Scrubbers include Animal Feed/ Nutrients Processing, Food Processing, Textile Manufacturing, Mining/Mineral Processing, and Printing. Venturi Scrubbers are also great abatement systems for some smoke removal applications.
