WET-TYPE AIR CLEANER AND WET-TYPE DEVICE FOR PURIFYING EXHAUST GASES, WHICH USE CENTRIFUGAL IMPELLER Russian patent published in 2009 - IPC F01N3/37 F01N3/04 B01D45/14 B01D47/06 

FIELD: engines and pumps.

SUBSTANCE: air cleaner includes gas suction channel (405), liquid tank (401) and gas-liquid centrifugal separator (407) in which centrifugal impeller (408) rotates suction air. In gas-liquid centrifugal separator (407) the housing and cylinder for gas passage are mounted so that the formed vortex flow in which centrifugal force is created, can pass certain distance along them. Gas-liquid centrifugal separator (407) has the first vortex chamber and the second vortex chamber. The first vortex chamber is made between housing and cylinder for gas passage. The second vortex chamber is made in gas passage cylinder. Gas suction channel (405) is mounted in front of gas-liquid centrifugal separator (407) for gas to move through it. Liquid tank (401) is connected to gas suction channel (405) for supplying washing water to gas suction channel (405) through liquid sprayer (403). Air pollutants entering through gas suction channel (405) are collected by using washing water. Air is cleaned with gas-liquid centrifugal separator owing to difference of specific weight and washing water.

EFFECT: increasing cleaning degree.
