Description

The invention relates to a technique for dry purification of gases from dust and aerosols in aspiration and ventilation systems, and can be used in construction, food, chemical and other industries.

The closest in technical essence and the achieved effect is a tubular dust precipitator (Tubular dust precipitator: Pat. No. 2701836 Russian Federation: IPC 51 B01D 45/08, B01D 45/06 (2019.02) / E.V. Romanyuk, O.S. Kaliev, D.V. Kargashilov, applicant and patent holder: Ivanovo Fire and Rescue Academy of the State Fire Service of the Ministry of Emergency Situations of Russia - No. 2701836; application 30.04.2018; publ. 01.10.2019 - Bull. No. 28), consisting of a cylindrical-conical body, coaxially the inlet and outlet nozzles connected to it, through which the cleaned gas flow is supplied from the bottom up, the baffles fixed inside the body differ in that the baffles are perforated with holes, with 57 holes in each of the 1st, 2nd, 5th, 6th below the partition are located in lines at an angle of 22.5 ° along the diameters of the partition and connected by tubes of equal diameter in pairs: the 1st and 2nd partitions, the 5th and 6th partitions; and 44 holes of each of the 3rd, 4th, 7th and 8th baffles are also located in a line at an angle of 22.5 ° along the baffle diameters and offset from the center by a distance of 1 hole diameter with respect to the holes, located on the 1st, 2nd, 5th and 6th partitions and are connected by tubes of equal diameter in pairs: the 3rd and 4th partitions, the 7th and 8th partitions.

The disadvantage is the inability to control the efficiency and low efficiency when cleaning from fine dust.

The technical objective of the invention is to increase the efficiency of cleaning dusty gases from dust and controllability of the design by creating movable structural elements that allow you to control the turbulence of the flow inside the device.

The technical problem is achieved by the fact that in an adjustable tubular dust collector, consisting of a cylindrical-conical body, coaxially connected to it by inlet and outlet pipes, through which the gas flow to be cleaned is supplied from the bottom up, partitions fixed inside the body are perforated with holes, with 57 holes in each of the 1st , 2nd, 5th, 6th partition from the bottom are located in lines at an angle of 22.5 ° along the diameters of the partition and connected by tubes of equal diameter in pairs: 1st and 2nd partitions, 5th and 6- th partition; and 44 holes of each of the 3rd, 4th, 7th and 8th baffles are also located in a line at an angle of 22.5 ° along the baffle diameters and offset from the center by a distance of 1 hole diameter with respect to the holes, located on the 1st, 2nd, 5th and 6th partitions and connected by tubes of equal diameter in pairs: the 3rd and 4th partitions, the 7th and 8th partitions, what is new is that the tubes are made from flexible corrugated material; in the center, an axis rotating from the electric motor passes through the entire dust precipitator; The 2nd, 4th, 6th and 8th partitions are rigidly fixed by fasteners on the axis of rotation located in the center of the dust trap, which allows them to move around their axis and are not fixed on the body of the trap and rotate in the grooves; and the 1st, 3rd, 5th and 7th are rigidly fixed on the dust trap body, have holes for the rotation axis and are not attached to the rotation axis.

The technical result of the invention is to increase the efficiency of cleaning the dust-gas flow from dust by bending the tubes by rotating the axis and partitions and the possibility of controlling the efficiency in this way.

The figure shows the proposed adjustable tubular dust collector.

Adjustable tube dust collector includes:

cylindro-conical body 10, inlet 9 and outlet 11 pipes coaxially connected to it, axis of rotation in the center of body 16, partitions 2, 4, 6 and 8 fixed with fasteners 18 on the axis of rotation, moving in grooves 17, and partitions 1, 3, 5 and 7, rigidly fixed to the housing and not attached to the axis of rotation 16, passing through the holes on them; moreover, the partitions are perforated with holes: 57 holes in each of the 1st, 2nd, 5th, 6th partitions from the bottom are located in lines at an angle of 22.5 ° along the diameters of the partition and are connected by corrugated flexible tubes of equal diameter in pairs: 1st and 2nd partitions, 5th and 6th partitions; and 44 holes of each of the 3rd, 4th, 7th and 8th baffles are also located in a line at an angle of 22.5 ° along the baffle diameters and offset from the center by a distance of 1 hole diameter with respect to the holes, located on the 1st, 2nd, 5th and 6th partitions and connected by corrugated flexible tubes of equal diameter in pairs; 3rd and 4th partitions, 7th and 8th partitions.

The proposed adjustable tubular dust precipitator works as follows. Dusty gas enters the body of the device 10 through the lower inlet 9, rises through the tubes 12, 13, 14, 15, fixed in perforated disks 1, 2, 3, 4, 5, 6, 7, 8. Due to the arrangement of tubes, reinforced in each subsequent pair of perforated disks, the dusty flow bends, dust particles actively collide with the walls of the tubes and each other, coagulate and settle. After that, the purified air exits through the upper outlet pipe 11. The efficiency is regulated by additional bending of the tubes by rotating the axis 16, which in turn rotates the 2nd, 4th, 6th and 8th partitions around its axis, moving the holes by which the tubes are reinforced, while the 1st, 3rd, 5th and 7th partitions with fixed tubes remain motionless. This allows you to change the tortuosity of the tubes and turbulize the flow.

The proposed adjustable tubular dust precipitator allows:

- regulate the efficiency of dust collection in automatic mode;

- improve the quality of air purification due to coagulation and coarsening of particles;

- save production space;

- increase the service life of the filter in two-stage dust collection systems.
