|Air pollution control equipments are the devices to minimize toxic pullulated gases into the air. There are few pollution control equipments for vehicles and industries to reduce toxic effects of gases in Air. |
Wet Scrubbers: It is a pollutant remover from furnace fuel gas and from other gas streams. It is used in large Power plants, fertilizer plants, steel plants and many other industries. Advantages associated with wet scrubbers in air pollution control applications include their capacity to withstand high temperatures and moisture levels, they necessitate a smaller operating space due to compact equipment and they have the ability to neutralize corrosive gases. Applications of wet scrubbers include exhaust cleaning, the treatment of industrial process gas streams and the incineration of medical waste.
Electrostatic Air Cleaner - This system is also known as ESP, which is a collecting device to force and remove specific mixture from gases. ESP system is used in oil refineries and pulp mills etc.
Gas Flare (Flare Stack) is an erected chimney on oil wells, landfills, refineries and chemical plants. On landfills waste gases are burnt through Gas flare.
EGR (Exhaust Gas Recirculation) - EGR technique is used to reduce NOx. This technique is used in diesel and gasoline engines.
Dust Cyclones: This device use vortex separation to remove particulate matter from gas or air. Exhaust gas recirculation and catalytic converter reduce Nitrogen Dioxide and Nitrogen oxide in gasoline and diesel engines.
Catalytic Converter: This air pollution control system is used in internal combustion engines to reduce toxicity from the emitted gases. Vehicles and trains are using this system to exhaust the gases. This equipment is even use in other industries like mining, forklifts and gen set etc.
Bag Filter: Bag filter is another equipment to separate out dust from the gases before exhausting to the atmosphere. During this process dusty air enters the bag filter. The dust separates inside the bag air filter chamber. The dust is accumulated and dislodged from the bags while the air passes through the bag filter and dust free air is exhausted in the atmosphere through centrifugal blower and fans.
There are many other air controlling equipments for Industrial applications. Government of majority developing countries have taken drastic steps confounding the environment policy for Industrial production houses, factories to control the air pollution through various mechanism establishing as per the production requirements. This is the prime duty of every citizen of world to establish proper air and water pollution control system in their residential or commercial premises to save the valued atmosphere to live.
