Venturi scrubber systems were developed to accommodate numerous processes to catch sub-micron particles, with minimum downtime and maintenance. They show excellent outcomes in procedures that necessitate high particulate removal efficiency, elevated inlet gas temperatures, substantial particle loading, and a significant proportion of solids in the liquid recirculation loop.
Venturi scrubbers are capable to solve problems in mining, chemical, food, explosive dust, and metallurgical industries. They offer over 99% efficiency for sub-micron particles and have a long operational lifespan, requiring very little maintenance.
Additionally, it is possible to design a Venturi scrubber with special parameters for air treatment applications where users need “high performance at low-pressure drops, adjustability of the venturi rod deck or compact, low profile design to suit available space”. These Venturi scrubber systems may include self-draining and don’t require water level control.
The design of a standard Venturi wet scrubber includes a “wet approach” venturi followed by a liquid entrainment separator. Polluted gases flow into the Venturi scrubber and at this point interact with a unique scrubbing solution moving down the converging walls of the scrubber.
Subsequently, the contaminated gas and liquid streams collide at the Venturi scrubber throat, producing droplets that entrap dust particles. Finally, the dust/solution mixture is removed from the scrubber separator bottom drain, while the treated gas passes out the top of the separator. The design of the Venturi scrubber system requires minimum maintenance because it uses open pipe liquid inlets and does not have spray nozzles.
One more type of Venturi scrubber is distinguished which is a Multi-Venturi air treatment device. This wet air scrubber comprises several rods arranged to produce a venturi effect between each rod. Therefore, Venturi wet scrubbers provide higher efficiency at lower pressure drops and solution-to-gas ratios than traditional Venturi scrubber systems.
The multi-Venturi scrubber functions on the principle of the venturi-rod deck, where contaminated gases flow in and interact with scrubbing water at the same time. The speed of gas increases rapidly. When the gases leave the venturi-rod area, the speed slows down leading to the larger particle-laden droplets falling out of the stream. Finally, the scrubbing solution is collected by falling down the Venturi scrubber floor to the drain trough, while treated and dewatered gases exit via the scrubber outlet.
If you are looking for the best air treatment device to improve air quality, Redwood Technology offers a cutting-edge type of wet scrubber – a Multi-Vortex wet air scrubber.
Redwood technology is a fast-growing vendor of wet air scrubbers. The multi-vortex scrubber can remove gas emissions, dust, vapors, and other pollutants from a gas stream. It is an innovative technology created to save water that makes it more cost-efficient and differs from other types of scrubbers.
