B01D47/02 - CPC Classification

Classification description:

Separating dispersed particles from gases, air or vapours by liquid as separating agent by passing the gas or air or vapour over or through a liquid bath

Sub-classes:

B01D47/021 » {by bubbling the gas through a liquid bath} 118
B01D47/022 » {by using a liquid curtain } 22
B01D47/024 » {by impinging the gas to be cleaned essentially in a perpendicular direction onto the liquid surface} 39
B01D47/025 » {by contacting gas and liquid with a static flow mixer } 19
B01D47/027 » {by directing the gas to be cleaned essentially tangential to the liquid surface} 42
B01D47/028 » {by directing the gas through a wetted wire mesh or a perforated plate } 19
