Abstract

Usage: for the separation of media in the chemical, metallurgical and other industries. SUMMARY OF THE INVENTION: Above the binary cyclone there is a chamber with a filter consisting of a granular layer and corrugated cloth filters fastened underneath it on arcuate frames. The camera communicates with the separated phase channel collector formed by the outer surface of the housings and a flat wall attached tangentially to them from the outside. The channel at the lower end in the collector has a shutter in the form of overlapped lamellas around the channel perimeter of elastically deformable metal plates. A partition in the form of a truncated cone with a central opening and a fan are located above the chamber with the filter. 3 ill. Yo

Description

FIELD OF THE INVENTION The invention relates to devices for separating media, and can be used in the chemical, engineering, and other industries.

The known binary cyclone 1 comprises two conjugated cylindrical-conical bodies, drain pipes and a drain chamber with a pipe to exit the clarified suspension. A common inlet pipe with a divider located inside a concentrically mounted tube with a liner is located in the interface between the housings.

The disadvantage of this device is the difficulty in operation due to the pollution of the outlet (drain) chamber due to the low efficiency of the capture of the solid phase in cyclones and its precipitation in the chamber under the influence of gravitational forces and pressure losses by the flow.

A cyclone 2 is known, comprising a shaking device, electric heaters and a spray.

The disadvantage of this cyclone is the insufficient cleaning efficiency with significant energy consumption of the apparatus.

Closest to the present invention is a binary cyclone 3 containing two mating cylindrical bodies, an inlet pipe located in the mating zone of the bodies, upper axial pipes for draining the medium into the filter chamber located above the bodies, the outlet pipe of the cleaned medium and the separated phase collector .

The disadvantage of this device is the low cleaning efficiency.

The aim of the invention is to increase the efficiency of air purification.

For this, the binary cyclone is equipped with a partition mounted above the filter in the form of a truncated cone with a central hole, a fan placed above it and attached externally to the housings by a tangent flat wall, forming N

a dust outlet channel with a surface of the housings, open at the top with a filter and a shutter at the bottom in the form of overlapping elastically deformable metal plates installed in the collector around the channel perimeter, and the filter is made in the form of a layer of granular material, under which on arched frames connected between corrugated cloth filters are installed by themselves and with the walls of the chamber.

In FIG. 1 is a schematic vertical section of a binary cyclone; FIG. 2 is a section I-I of FIG. 1; in FIG. 3 - node I of FIG. 1.

The binary cyclone contains two conjugated cylindrical-conical bodies 1, an inlet pipe 2, a pipe 3, an output chamber 4 with a filter arranged therein, made in the form of a granular filter 5, under which corrugated corrugated frames are connected to each other and to the walls of the output chamber 4 cloth filters 6, a cone-shaped nozzle 7, mounted on the base of the grain filter 5, under the outlet nozzle 8 with a fan 9 installed in front of it, located along a common tangent to the cylindrical conical surface m housings 1 partition 10 forming the dust discharge passage 11 from the chamber 4 in a dust receptacle 12, which is provided in the exit gate 13 of resiliently deformable plates disposed along the perimeter of the channel opening 11 to overlap each other.

The operation of the binary cyclone is as follows. Dusty air is supplied through the inlet pipe 2 to the mating cylindrical-conical bodies 1, where, under the action of centrifugal forces, large particles are separated on the walls, which slip into the dust collector 12, and the partially purified air stream passes into the exhaust chamber 4 through the exhaust pipes 3. Further, the air stream the passage through the corrugated cloth filters 6 is cleaned of fine particles, which, under the action of gravitational forces, fall into the dust channel 11, in addition, the configuration of the filters contributes evenly at flow distribution in the chamber, eliminating the occurrence of secondary currents, which reduces the time Withania fine particles. Purified air, passing through the granular filter 5, is cleaned of harmful gas components (for example, CO2 - when the filter is filled with activated carbon granules) and is removed through the outlet pipe 8 by fan 9. For

to prevent leakage into the outlet chamber 4 from the dust collector 12 during its unloading, the dust outlet 11 is provided with a shutter 13, the metal plates of which overlap each other and close

passage to the exit chamber 4.

Technical advantages of the claimed design are that in the outlet chamber air is purified from fine particles and harmful gas components, as well as the removal of solid particles from it, which improves the efficiency of air cleaning.
