VORTEX DUST COLLECTOR Russian patent published in 2018 - IPC B04C3/06 B01D47/06 B01D45/12 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to wet dust collecting devices and can be used in chemical, textile, food, light and other industries for purification of gases, mainly from fine particles and submicrometer dimension particles. Swirling dust collector comprises a cylindrical separation chamber with upper and lower air supply ducts, consisting of consecutively located: inlet duct, confuser, neck, diffuser and air entrainment jet. At the bottom of the separation chamber there is a jet for input of primary air with a stabilizing device, a cylindrical radome located coaxial with the axial lower air supply duct, vane swirler, baffle and boot. In the upper part of the separation chamber there is a jet for input of secondary air, a vane swirler, stabilizing radomes and a coaxially located outlet jet. In addition, in the confuser of each air supply channel, a nozzle is installed in front of the neck to meet the air flow. At the same time, a nozzle with the possibility of water spraying is installed in the primary air supply channel, the size-consist of which is 10÷70 mcm, and in the secondary air supply channel – with the possibility of spraying with liquid, thesixe-consist of which is 2÷10 mcm. At the same time, the liquid flow rate for spraying of the primary air flow is taken as 2÷3 times more than for spraying of the secondary air stream.

EFFECT: increase the efficiency of the dust collecting device, improve the quality of the air to be cleaned and reduce energy costs when cleaning dusty air.
