Description

one

The invention relates to devices for cleaning dust from vent emissions into the atmosphere and can be widely used in various industries.

A device for centrifugal gas cleaning from suspended particles is known, which includes a housing with vacuum and separation chambers, a conical core with swirlers located at the inlet and outlet.

The known device for centrifugal gas cleaning does not provide the necessary cleaning of fine dust with raising the concentration of dust in emissions to the limits of sanitary standards.

In order to increase the cleaning efficiency in the proposed device, the conical core is made hollow with a diffuser at the inlet, and the swirler at the outlet is made in the form of nozzles with horizontal and vertical guides.

FIG. 1 shows the proposed device for centrifugal gas cleaning, a section; in fig. 2 shows a section A-A in FIG. one; in fig. 3 - node B in FIG. one; in fig. 4 is a section along b-b in FIG. 3

The device for centrifugal cleaning consists of swirlers 1 and 2 of the external and internal circuits of the air (gas) flow, shell 3 with flanges, blades 4 (gas turbine type), diffuser 5, at the inlet of the conical core 6, nozzles 7 with radial vertical 8 and horizontal 9 are directed by them, the separation chambers 10, on the conic surface of which are arranged in a staggered order at an angle of more than 10 ° to the horizontal plane of the cross section of the dust-removal ball 11 and the rarefaction chamber 12, made in the form of a truncated cone and divided 13 partitions into two half-rings

and provided with windows 14, a semi-circular symmetrical collector 15, a junction 16 with an outlet pipe 17 and a cylindrical separator 18. A device for centrifugal gas cleaning works as follows.

Ventilation emissions enter the swirlers 1 and 2, where they receive rotational motion.

From the swirler 1, the rotating air gas flow enters the cylindrical separator 18, where, under the influence of centrifugal inertial forces, dust particles are thrown to the periphery and the largest dust fractions are separated from

air (gas) flow with a concentration of about the cylindrical surface of the separator 18, then the rotating streams of concentrated dust and gas enter the separation chamber 10. In the chamber 10 under

the effect of overpressure and centrifugal inertia forces, as well as the dilution created by the fan in chamber 12, further separates the main mass of dust from the air (gas) flow and concentrates it around the conical surface with dust separating bars 11. Concentrated main dust mass in Vs-Vi, parts of the volume of air discharged from the exhaust pipe of the fan, through the dust-removal slots 11, enter the chamber 12. Through the passage openings 14, the dust enters the floor, an annular symmetrical collector 15, and then through the cross d 16 is directed by ductwork, such as the second stage fine cleaning. The purified gas from the device shimmers to the atmosphere.

To impart highly dispersed dust and sublimations of additional centrifugal inertia force and press them with an internal swirling flow to the dust separation slots 11 into the conical core, Vs part of the dust-laden gas is supplied from the total volume. The rotating flow formed inside the core acts by centrifugal inertial forces on the fine dust and sublimates, presses them to the dust removal slots AND, and then the concentrated dust is taken out of the dust concentrator through the duct and enters the second fine cleaning stage.
