SU466036A1 - Centrifugal wet dust collector - Google Patents

Description

The invention relates to the design of wet dust collectors with a rotary atomizer, which can be used in industrial plants for cleaning the aspiration air from mechanical impurities, as well as in heating and ventilation systems for humidifying the forced air.

A centrifugally wet dust collector for cleaning gases is known, which includes a housing, a disk rotor, and a fluid supply device.

The disadvantages of the known centrifugally wet dust collector are that the gripping area and the perimeter of the sprayed liquid are limited, which reduces the gas cleaning efficiency.

The proposed dust collector differs from the known one in that between the rotor disks there are installed reflectors made in the form of truncated cones interconnected by smaller bases and large bases adjacent to the disks. The end surfaces of the discs can be made with a serrated groove.

FIG. 1 shows a centrifugally wet dust collector, an incision; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. 2; in fig. 4 — node I in FIG. one.

Centrifugally wet dust collector includes a housing 1, which in the presence of flanges 2 can be installed in the duct, as part of it. In the cylindrical part of corus 1 on the support 3 there is mounted a disk rotor made in the form of a set of disks 4 fixed on a common shaft 5 on which a fairing 6 is seated on the input side of the gas to be purified.

Between the disks 4, truncated cones 7 are installed, the conical surfaces of which face smaller bases towards each other.

A liquid supply device 8, made in the form of a comb, is installed in the housing, the pipes 9 of which are inserted into the gaps between the disks. Separator 10 is installed in the narrowing part of the housing at the outlet of the water spray and cleaning zone. In the lower part of the housing 1 and separator 10 there are funnels 11 with drains that serve to collect and remove sludge.

The disks 4 on both sides of the perimeter have serrated grooves 12. In the outermost disks, such grooves are made only from the inside.

Works centrifugally wet dust collector as follows.

Dust-laden gas enters housing 1 and, the passage of the fairing 6 enters the zone of intensive spraying of water entering through nozzles 9. Water exiting them spreads over the surfaces of truncated cones 7 and enters discs 4. Falls onto the surface of the disk sprays to form a uniform plume of fine droplets wetting the dust particles and causing them to coagulate and sludge fall out. The purified gas passes through the separator 10. The sludge from the housing 1 and the separator 10 enters the funnels 11, from where it is removed through the drains to a further separation or sewage system.
