Description

The invention relates to the separation of multiphase systems using centrifugal forces and may find application in various branches of the national economy, for example, with the separation of powdered materials from gas.

The purpose of the invention is to increase the gas cleaning efficiency by creating a back pressure in the gap between the rotor and the plate.

FIG. 1 shows the device; lengthwise cut; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a section BB in FIG. 2

The device contains a cylindrical housing 1 with a tangential feed w, it is equipped with a piston 2 and an outlet nozzle 3, an annular bottom plate 4 fixed on the body with blades 5, and an annular upper diaphragm 6, a tangential nozzle 7 for supplying clean gas, laid out between A filter rotor 8 assembled from blades 9 is provided with a spigot and outlet nozzles. A separating disk 10 with tubular blades 11 is mounted between the blades of the filter rotor 8. The blades 9 are fastened with straps 12. The third rotor 8 is mounted on a vertical shaft 13. The annular plate 4, the separating disk 10 and the diaphragm 6 form a chamber 14 and a chamber 15. In the lower part of the housing there is a discharge nipple 16. The blades 5 are mounted on the outer surface of the plate 4 with the output edges 17 displaced in the direction of rotation of the rotor. The pipe 7 is connected to the housing 1 between the diaphragm 6 and the disk 10.

When operating the device air mixture (for example, gas and powdered material)

through pipe 2 into housing 1. Ter energy, powdered material is deposited in the lower part of housing 1. The upward flow 1 ase that forms in housing 1 enters the cavity of the filter rotor 8. Particles of powdered material 1UDD are ejected by the centrifugal field again to the inner surface of housing 1 and the cleaned gas is directed to the outlet nozzle 3. In this case, the tubular blades 11 of the separating disk 10 take from the chamber 14 fresh air coming in through the nozzle 7 from the surrounding medium and feed it into the chambers at 15 on the annular plate 4. The blades 5 located on the annular plate guide the air further into the gap between the filter rotor and the annular plate. Thus, the cleaned air compresses the gap between the filter rotor and the ring plate 4 of the cylinder-conical body, completely eliminating the penetration of the air mixture through the gap, as well as clogging of the powder-like material between the ring plate and the rotating rotor by particles, which increases the degree of fractional purification and reliability of the device. Avoid release of polluted air to the environment.

The introduction of an additional tangential inlet pipe allows you to take clean air from the environment into the intermediate cavity formed between the housing and the diaphragm separation disk, and then feed it using tubular blades located in the separation disk to the gap between the filter rotor and ring plate.
