Abstract

The invention relates to dust collection, in particular, to vortex dust collectors, and can be used in the chemical, petrochemical, biological, food, building materials and other industries. The purpose of the invention is to increase the efficiency of dust collection due to the intensification of the separation process in the central zone. The vortex dust collector contains a cylindrical body 1, inlets 3, 6 of dusty gas and a nozzle 7 for removal of purified gas. The screen 8 installed under it is made in the form of a truncated cone with a large base up and provided with a rotation drive. The truncated cone is formed by a helical spiral with winding in the direction opposite to the direction of rotation of the streams. The presence of a rotating screen 8 allows a stable hydrodynamic environment to be formed to effectively clean the dust-air mixture from the fine fractions of dust in the central zone of the body due to the intensification of rotation of the axial rotational flow, more uniform removal of the cleaned gas to the outlet nozzle through the slit holes between the turns of the screen helix 8. 1 .P. f-crystals, 1 tab., 3 ill.

Description

And combining it with terrains to clean a tayu, suspended particles using a centrifugal separation method, in particular, to vortex: dust collectors, and can be used in chemical, petrochemical, biolotics, food, building materials and other industries.

The aim of the invention is to increase the efficiency of dust collection due to the intensification of the separation process in central Europe.

the body exhibits a suction effect in the inter-turn gap and a drop in radial resistance to gas movement occurs.

The rotating screen 8 prevents large dust particles from being accidentally thrown off the wall of the separation chamber into the axial part of the dust collector, which occurs in a number of designs of vortex dust collectors.

When the coils of the coil 1 1 move in two mutually perpendicular planes, there is a rapid alternation of the coils and between the coils of the gaps, the rotational body becomes almost impermeable to dust particles MOVING in axial or radial directions relative to the separating chamber.

Under laboratory CONDITIONS, comparative bench tests of a vortex dust collector with a separation chamber diameter of 145 mm with a rock device and without it LL were applied.

According to experimental nosepieces (flash 3), the graphic dependence of the effects of dust capture by the medium particle size, curve 13 characterizes the degree of dust collection in a swirl vortex dust collector, and curve 1 1 in the dust collector without using a rotor device, the graph reflects the increased efficiency of the string and the white space pattern. dust collector, which is more pronounced in the field of fine dust
