Märgpesurite

Märgpesurite, also known as wet scrubbers, are air pollution control devices that use a wetting liquid, typically water, to remove particulate matter and gaseous pollutants from an industrial exhaust stream. The process involves bringing the polluted gas into contact with the scrubbing liquid, causing pollutants to be captured in the liquid. This contact can occur in various ways, such as spraying the liquid into the gas stream, passing the gas through a curtain of liquid, or bubbling the gas through a body of liquid.

The effectiveness of a märgpesur depends on factors like the type of pollutant, the size of particulate matter, the gas flow rate, and the properties of the scrubbing liquid, including pH and flow rate. Different designs exist, including spray towers, packed bed scrubbers, and venturi scrubbers, each suited for different applications. Particulate matter is removed through impaction, interception, or diffusion onto the liquid droplets or surfaces. Gaseous pollutants are removed through absorption into the liquid.

After the scrubbing process, the liquid, now containing the captured pollutants, is typically treated to remove the contaminants before being discharged or reused. This treatment can involve settling, filtration, or chemical processes. Märgpesurite are widely used in industries such as power generation, chemical manufacturing, and metal processing to comply with air quality regulations and protect the environment. They are versatile and can handle a range of pollutants, but require careful design and maintenance to ensure optimal performance.
