Particulate scrubbers, also known as venturi scrubbers, are air pollution control devices used to remove particles and other pollutants from industrial exhaust gases. The system operates by passing the polluted gas stream through a venturi throat, where water is sprayed into the stream, creating a mist. This mist captures the particles and pollutants and drags them out of the gas stream. The scrubbed gas then passes through a mist eliminator, where any remaining mist droplets are removed before being discharged into the atmosphere.
Venturi scrubbers are typically used in applications where there is a high concentration of particulate matter, such as in metal finishing operations or coal-fired power plants. They are also commonly used in applications where wet scrubbers may not be suitable, such as when the exhaust gas is at a high temperature.
Venturi scrubbers can be designed to handle a range of gas volumes and particle sizes. The effectiveness of the scrubber depends on factors such as the size and concentration of the particles, the gas temperature and humidity, and the scrubber design.
Overall, particulate scrubbers are an effective solution for controlling air pollution and improving air quality in industrial settings. They offer a reliable and cost-effective means of reducing particulate emissions and can be customized to meet the specific needs of a wide range of industries.
