Air Pollution control Equipments

Air pollution is the introduction of chemicals, particulates, biological materials, or other harmful materials into the Earth's atmosphere, possibly causing disease, death to humans, damage to other living organisms such as food crops, or the natural or built environment. The atmosphere is a complex natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems.

The following items are commonly used as pollution control devices by industry or transportation devices. They can either destroy contaminants or remove them from an exhaust stream before it is emitted into the atmosphere.

·         Particulate control

·         Mechanical collectors (dust cyclones, multicyclones)

·         Electrostatic precipitators An electrostatic precipitator (ESP), or electrostatic air cleaner is a particulate collection device that removes particles from a flowing gas (such as air) using the force of an induced electrostatic charge. Electrostatic precipitators are highly efficient filtration devices that minimally impede the flow of gases through the device, and can easily remove fine particulates such as dust and smoke from the air stream.

·         Baghouses Designed to handle heavy dust loads, a dust collector consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system (distinguished from air cleaners which utilize disposable filters to remove the dust).

·         

·         Particulate scrubbers Wet scrubber is a form of pollution control technology. The term describes a variety of devices that use pollutants from a furnace flue gas or from other gas streams. In a wet scrubber, the polluted gas stream is brought into contact with the scrubbing liquid, by spraying it with the liquid, by forcing it through a pool of liquid, or by some other contact method, so as to remove the pollutants.

·         Scrubbers

·         Baffle spray scrubber

·         Cyclonic spray scrubber

·         Ejector venturi scrubber

·         Mechanically aided scrubber

·         Spray tower

·         Wet scrubber

·         NOx control

·         Low NOx burners

·         Selective catalytic reduction (SCR)

·         Selective non-catalytic reduction (SNCR)

·         NOx scrubbers

·         Exhaust gas recirculation

·         Catalytic converter (also for VOC control)

·         VOC abatement

·         Adsorption systems, such as activated carbon

·         Flares

·         Thermal oxidizers

·         Catalytic converters

·         Biofilters

·         Absorption (scrubbing)

·         Cryogenic condensers

·         Vapor recovery systems
