SWIRL DUST SEPARATOR FOR SYSTEMS OF PNEUMATIC TRANSPORT AND ASPIRATION Russian patent published in 2001 - IPC

FIELD: dry inertial cleaning of gases in counter-swirled flows. SUBSTANCE: swirl dust separator has a cylindrical body with tangential branch pipes for supply of primary and secondary flows of dust-laden gas, axial branch pipe for discharge of cleaned gas in the body upper part, and dust separator in its lower part. Inlet pipe of gas primary flow has a swirler installed on inlet end of gas duct beyond the body of swirl dust separator, and regulators of low rate are installed in inlet tangential branch pipe of primary and secondary flows of dust-laden gas. It provides for regulation of flow rate of gases incoming into dust separator and value of parameters of swirling of gas flows with preserved configuration and increased cleaning efficiency for various types of dust. EFFECT: higher efficiency. 2 cl, 3 dwg
