Description

The invention relates to a technique designed for dry cleaning of gases from dust and can be used in aspiration systems for food, construction, engineering, pharmaceutical, metallurgical, woodworking and other industries.

The closest in technical essence and the achieved effect is a bulk filter with a regeneration system [Bulk combined filter with a regeneration system: US Pat. No. 2629683 Ros. Federation: IPC 51 BO1B 53/00, BO1B 24/04 / E.V. Romanyuk, M.A. Pinaev; applicant and patent holder: E.V. Romanyuk. - No. 2629683; dec. 09/29/2015; publ. 08/31/2017. - Bull. No. 25], including a cylindrical body with inlet and outlet fittings, a two-layer filter cassette with a perforated bottom and partitions, movable supports, a shaft for holding and opening the cassette, a block of purge perforated tubes fixed on a rod for raising and lowering it, which serves to regenerate the cassette .

The disadvantage is the complexity of design and operation, respectively, reduced reliability and high cost, the complexity of regeneration, high power consumption. Another disadvantage is the uneven supply of dusty flow to the filter cassette.

The technical objective of the invention is to increase the reliability and simplicity of design, increase the efficiency and reliability of regeneration and cleaning, reduce energy consumption.

The technical problem is achieved by the fact that in a bulk filter consisting of a housing and a filter cassette with bulk material mounted on a shaft, what is new is that the housing has a spherical shape and smoothly passes into a cone-shaped dust-laden air inlet located at the bottom and a cone-shaped outlet of the purified air. gas, located on top, and on a shaft rotated by an electric motor and fixed on the housing, located perpendicular to the axis of the housing, a spherical filter cassette is installed, consisting of sectors made of a metal mesh and fastened with stiffening arcs to maintain the spherical shape of the filter cassette filled with bulk filter material , the size of which depends on the properties of the dust-gas flow, and in the lower part of the housing up to the filter cassette, on the side of the dusty gas supply, a circular guide blocking blockages is installed.

The technical result of the invention is to increase the efficiency of cleaning the dust and gas flow from dust due to the redistribution of the dust and gas flow over the filter surface and the effective automatically triggered self-regeneration of the bulk filter material by rotating the spherical filter cassette with the help of an electric motor.

The figure shows a bulk spherical filter with automatic self-regeneration.

A bulk spherical filter with automatic self-regeneration includes: a cone-shaped inlet pipe for dust and gas flow 1, a spherical filter housing 2, a cone-shaped pipe for the purified gas outlet 6, a spherical filter cassette 3, an electric motor 4, a circular guide 5 blocking blockages, cassette stiffening arcs 7, a rotation shaft of the filter cassettes 8, shaft fastening 9, bulk filter material 10.

The proposed bulk spherical filter with automatic self-regeneration works as follows.

The dusty gas enters from the bottom upwards into the spherical body of the device 2 through the cone-shaped inlet pipe of the dusty dusty gas flow 1; passes, being cleaned, through a spherical filter cassette 3 with bulk filter material 10 and reinforced with stiffening arcs 7 and exits through a cone-shaped outlet pipe 6, while the spherical shape of the filter cassette makes it possible to increase the thickness of the filter layer in the center of the apparatus, where it becomes more clogged with dust during filtering, than at the walls of the apparatus, and the circular guide 5 blocking gaps prevents the penetration of dusty air between the walls of the apparatus and the spherical filter cassette. This allows the filter material to be used more evenly and to extend its use without regeneration. Over time, the filter material becomes clogged with dust and must be regenerated. At the automation signal, the supply of dust and gas flow to the bulk spherical filter is stopped and the electric motor 4 is turned on, which drives the shaft 8 and the spherical filter cassette fixed on it. The bulk material of the filter 10 is mixed, freed from dust, which, pouring out through the bulk filter material and the metal mesh of the filter cassette down, is removed from the apparatus through the pipe 1. After that, according to the automation signal, the electric motor 4 stops, and then the dusty flow again begins to be fed into the cone-shaped pipe input 1 and filtration takes place with a stationary spherical filter cassette.

The proposed bulk spherical filter with automatic self-regeneration allows:

- increase the efficiency of dust and gas flow cleaning;

- perform self-regeneration without additional energy resources;

- extend the life of the filter cassette.
