Märkäpesureiden

Märkäpesureiden, also known as wet scrubbers, are air pollution control devices that use a liquid, typically water, to remove particulate matter and gaseous pollutants from an industrial exhaust stream. This process involves bringing the dirty gas into direct contact with a scrubbing liquid. The pollutants are transferred from the gas phase to the liquid phase, either by dissolving, absorbing, or impaction.

There are several types of wet scrubbers, each with its own method of contact between the gas and liquid. Venturi scrubbers are known for their high efficiency in removing fine particulate matter due to the high velocity created in a constricted throat where the liquid is injected. Spray towers use spray nozzles to atomize the liquid into droplets, which then fall through the rising gas stream, capturing pollutants. Packed bed scrubbers utilize a bed of packing material, such as rings or saddles, to increase the surface area for gas-liquid contact. Tray scrubbers involve gas passing through a series of trays, each covered with a liquid layer, promoting scrubbing action.

The effectiveness of a wet scrubber depends on factors such as the type of scrubber, the scrubbing liquid used, the gas flow rate, and the physical and chemical properties of the pollutants. The scrubbing liquid, once it has absorbed the pollutants, is typically treated or disposed of. Märkäpesureiden are widely used in various industries, including power generation, chemical manufacturing, and metal processing, to comply with environmental regulations and improve air quality.
