Description

The invention relates to a technique for cleaning industrial emissions from particles suspended in a gas and can be used in food, construction, chemical and other industries, where there is a need to clean gas from wet solid particles with a sticky component (clay), with large (0, 2 to 20 mm) the dispersion of sizes of solid particles, their shape and other physical characteristics.

Known centrifugal gas filter (AS No. 1263313 (USSR), B01D 45/14 BI No. 38 1986), comprising a housing with a tangential inlet pipe, a cover with an exhaust pipe, a rotor coated with filter material and connected to a fan, an unloading device. Its disadvantage is the incomplete purification of gas from wetted solid particles of gas (air) with the presence of a sticky component, with a large (0.2 to 20 mm) spread in sizes of solid particles, their shape and other physical characteristics (fragment fractions).

A device for cleaning gases, comprising a housing placed inside it with the possibility of rotation from the drive by a cylindrical filtering rotor, dust collector (and.with. No. 1611409 (USSR) B01D 46/26 1990). Its disadvantage is the incomplete purification of gas from wetted solid particles of gas (air) with the presence of a sticky component, with a large (0.2 to 20 mm) spread in sizes of solid particles, their shape and other physical characteristics (fragment fractions).

Known gas filter (AS No. 1398889 (USSR), B01D 46/26, B04C 9/00 BI No. 20 1988;) adopted as a prototype containing a conical-cylindrical housing with a tangential inlet pipe mounted on a shaft hollow rotor coated filtering material, cover with exhaust pipe, fan, electric drive.

The disadvantage of the prototype is also the incomplete purification of gas from wetted solid particles of gas (air) with the presence of a sticky component, with a large (0.2 to 20 mm) spread in sizes of solid particles, their shape and other physical characteristics (fragment fractions).

The technical result is to eliminate this drawback, that is, increasing the efficiency of gas purification from solid, including wetted, particles with a large spread (0.2 to 20 mm) of particle sizes, their shape and other physical characteristics (fragment fractions).

The technical result is achieved by the fact that the device for gas purification, containing a conical-cylindrical body with a partition separating its upper part, a centrifugal filter, inlet and outlet nozzles, an electric drive, according to the invention, is equipped with a protective casing made in the form of a cylinder mounted on a partition inside the lower part of the casing with a gap relative to the centrifugal filter, flushing nozzles located under the partition between the casing and the protective casing, and a collection of fragment fractions, under-adjoint case.

The device is illustrated by the drawing which shows a diagram of a device for gas purification.

The drawing 1 shows a diagram of an installation for gas purification.

The device comprises a base 1, a pipe 2, an inlet pipe 3, a cylindrical body 4, with a baffle 5 separating its upper part 6, a centrifugal filter 7 mounted on the shaft 8 with a pulley 9, which is connected by a belt drive to the pulley 10 on the shaft of the electric motor 11.

The lower part 12 of the casing is made conical and has a valve 13, under which a collection of fragmentation fractions 14 is located, located under the lower part 12 of the casing. Flushing nozzles for supplying water 15 are located under the partition 5 between the housing 4 and the protective casing 17. The outlet pipe 16 is designed to exhaust cleaned air. To protect the filter 7 from large rebound particles, a protective casing 17 is provided, made in the form of a cylinder mounted on a partition 5 inside the lower cylindrical part of the housing with a gap relative to the centrifugal filter 7.

The device operates as follows. The humidified air in an amount of 1200-2400 m ³ / h with fragmentation fractions of up to 3.5 t / h is fed through pipe 2, the inlet conduit 3 into the housing 4 at a tangent, where under the influence of centrifugal force the coarse fractions are deposited on the walls and collected in the lower conical part 12 of the body, whence periodically by opening the valve 13 or continuously removed into the collection of fragmentation fractions 14 located under the lower part of the body 12.

Small fractions in the form of a wet aerosol settle on the outer surface of the rotating filter 7, form larger particles on its surface, which, under the action of centrifugal force, are thrown onto the walls of the casing 17 and fall down onto the lower conical part 12 of the housing. Having passed the filter 7, the cleaned air enters the upper part 6 of the housing, from where it is discharged by the outlet pipe 16.

Thus, the technical result is to improve the quality of air purification from wet particulate matter with the presence of a sticky component, with a large (0.2 to 20 mm) range of particle sizes, their shape and other physical characteristics.
