Abstract

<P>PROBLEM TO BE SOLVED: To provide a gas-liquid separator without enlarging the size and with simple constitution, which can effectively separate PM (particulate matter) in the exhaust gas or dust of toxic fine particles in gas like air, surely separate and collect even liquid attached to the gas-liquid separator containing a part of toxic substance, difficult to collect in the past, and prevent flowing out to the outside. <P>SOLUTION: An outer cylinder member 21 having a small diameter cylinder 23 imparting rotational force to an object gas-liquid mixture to be cleaned and flowed flowing in, is provided on the downstream side of a flowing-in port 22 formed on one end. Cylindrical bodies 27, 28 are adjacently disposed each other on the downstream side of the outer cylinder member. A communicating tube 30 with a smaller diameter than the cylindrical bodies is interposed between the cylindrical bodies to communicate them. A liquid receiver 32 is installed under the cylindrical bodies, and a gas outlet port 33 is provided at the most down stream side of the cylindrical bodies. <P>COPYRIGHT: (C)2006,JPO&NCIPI
