Venturi Scrubber For Incinerator

Venturi scrubber, designed to remove particulate matter (like dust, ash, or soot) from gas streams—commonly used in industrial pollution control, boiler systems, or air cleaning systems.

Working Principle: a venturi scrubber is designed to effectively use the energy from a high-velocity inlet gas stream to atomize the liquid being used to scrub the gas stream. This type of technology is a part of the group of air pollution controls collectively referred to as wet scrubbers.

Advantages of a Venturi System:

Medium to high removal ratio

Capable of removing various parameters

Highly cost effective

The primary function in which the wet scrubbers operate is to cause dust particles to attach to the water droplets. This contact occurs in three phases, these are:

Inertial Impact:

The direct impact of a particle with a water droplet, thus removing it from the emission gas stream. When the velocity between the two objects is relative this typically occurs.

Interception:

If a faster particle is not large enough to impact as water droplets, this gas particle may attempt to go around a slower or stationary object. As it does, its inertial energy will slow subsequently it is likely to impact a following water droplet in a scrubber system thus removing it from a the emission gas stream.

Diffusion:

Occurring in in particles typically less than .3 micron this process provides higher collection than would otherwise be expected due to the mixture of inertial impaction and Interception.

Acid Gas Removal

Calcium carbonate can also be added to water, with the resulting slurry sprayed into a flue gas scrubber. The process is found to be more efficient if a calcium hydroxide/water slurry is used, removing over 95% of Sulphur dioxide. The Sulphur dioxide is absorbed into the spray and precipitates as wet calcium sulphate. By re-circulating the slurry and injecting oxygen, calcium sulphate (gypsum) is formed which can be sold as a by-product. CaSO3 0.5H2O + 0.5O2 + 1.5H2O -> CaSO4 . 2H2O
