Abstract

COMBINED TSHPEOTDELITER, containing a cylindrical body with a mat, bunker, tangential inlet and axial exhaust pipe, a bag filter placed above it and a shaking mechanism, characterized in that, in order to increase its reliability by localizing explosive volumes, the body is equipped with an located below inlet pipe and overlapping the inlet of the exhaust pipe with a partition in the peripheral part and a divider in the form of an inclined plate attached to the wall of the housing, inside it cutout edge and the lid, in the wall of the exhaust pipe above the partition there is Hole-term and, under the partition wall of the housing is made of a low-strength The Air-permeable material such as tissue, and hopper connected with shaking mechanism.

Description

The invention relates to a device for air purification, transporting waste from technological processes, and can be used in engineering, woodworking 5 and other industries.

The purpose of the invention is to increase the reliability of the device by localizing explosive volumes. 10

In FIG. 1 schematically shows the proposed device; in FIG. 2, section AA in FIG. 1; in FIG. 3 building, isometry.

The separator contains a bag filter | 5 with a shaking mechanism (not shown), an aerodynamic separator body 2 with a tangential inlet pipe 3, an axial exhaust pipe 4, a hopper 5 connected to the body 20 by a wall 6 made of low-strength breathable material, a partition 7 with a cutout 8 and divider

9, attached to the inner edge of the cutout 8, the wall of the housing 1 and the cover 25

10. The lower hole of the exhaust pipe is equipped with a valve 11. An opening is made in the wall of the exhaust pipe 4

12.

The separator works as follows.

Air with transported waste enters the nozzle 3. Passing the curved part of the channel, the waste is pressed to the outer wall of the housing 2, fall under the divider 9 and with some air is sent to the hopper 5. In order to less disturb the structure of the velocity field of the rotating flow, the divider 9 may have perforation.

. The bulk of the air with a fine fraction (dust), passing through the aerodynamic separator, enters the bag filter 1 through the hole 12. The regeneration of the filter bags 1 and wall 6 is carried out simultaneously in a vertical plane using a shaking mechanism, which is associated with the upper mount of the sleeves and hopper 5 . To pour dust into the hopper 5 from the filter 1 at the time of shaking, valve 11 opens.

Improving the safety of the separator is ensured by reducing the likelihood of an explosive concentration in the hopper, the volume of which increased due to the lower part of the walls of the housing 2 made of breathable fabric, and by a decrease in the explosion force acting on the unit surface of the hopper and the breathable transition due to the presence of the partition 7.

The use of a wall of breathable material reduces the filtering surface of the sleeves. This is possible due to the selected location of this junction and its function as an air purifier, in addition to the function of an explosive discharge device.
