Air treatment as well as air pollution control play a crucial role in industrial enterprises. To solve the problem of a polluted environment, special air treatment devices for polluted gas media – scrubbers are used. Scrubber systems demonstrate high efficiency and find wide application among gas treatment systems.
An industrial wet scrubber is a device for cleaning gaseous media from various particulates: dust, fumes, smoke, aerosols, crystals of selenium oxide, tellurium, lead, and other similar substances. The wet air scrubber uses a wet method of gas treatment – the gaseous streams are washed with water or special solution, which captures polluting particles of almost any size, and then removes them from the device. Thus, volatile pollutants are removed from the gas environment by liquid treatment, turning into a sedimentary mass (sludge).
The main task of the wet scrubber is to catch and remove pollutants in the exhaust industrial and flue gases. The greatest demand for scrubber systems is at enterprises that emit pollutants into the atmosphere and require proper air pollution control. Such air treatment devices are obligatory for the organization of air exchange systems in the following industries: gas industry, ferrous and non-ferrous metallurgy, stone mining and stone refineries, oil and petrochemical industry, production of construction materials, mechanical engineering, energy, chemical technology, food production.
Classification of scrubbers by method of dust collection divides all installations into four main types:
- Packed bed scrubbers are presented in the form of large-sized cylinders with attachments of various shapes and an irrigation system inside the body. Such scrubber systems are effective for capturing highly soluble dust particles, acid or alkaline fog, simultaneous de-dusting, absorption and cooling of gas media;
- Centrifugal scrubbers have a cylindrical shape and are located vertically, the gas flow entering from the bottom of the system is not just in contact with water, but also rotates at high speed. Under the action of centrifugal force, the liquid catches solid dust particles that settle on the inner surface of the wet scrubber, and, accumulating, flow to the lower part of the system;
- Foam scrubber is based on the absorption method of air treatment, such a scrubber uses a special polydisperse composition during operation;
- Venturi scrubber – the main difference between this type of wet air scrubber is the use of a Venturi tube. The shape of this system is similar to a sand-glass. The gas is fed into the mouth of the unit, where it gains a high speed, forming turbulent flows, and mixes with the supplied liquid.
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.
