Description

(54) COMBINED DUST COLLECTOR

I

The invention relates to dust collection and is designed to trap dry sore from air in aspiration and industrial ventilation systems as well as ashes from exhaust flue gases and can be used in any branch of the national economy where air purification from solid impurities is required.

A device for wet gas cleaning is known, comprising a housing partially filled with liquid with nozzles for inlet and outlet of gas, a central tube immersed in a liquid and provided with a nozzle and a cone-shaped bowl Tf.

The device has one cleaning stage and therefore the gas cleaning efficiency is low.

The closest to the described invention to the technical essence and the achieved result is a combined dust collector, which contains a partially fluid-filled housing with inlet and outlet pipes, a centrifugal chamber equipped with a fairing and a rotary part

Enclosures, a device for wet scrubbing of gas, having an irrigator G2.

In this dust collector, a dry cleaning step is carried out with the help of a snail spinner and a spatula device, and a wet cleaning stage is carried out with a spraying device. However, the contact time of the two phases in such a device is not enough to ensure high trapping efficiency, the applied design of the spray device does not ensure that the finely dispersed spray liquid is completely wetted

KOCTW

In order to increase the efficiency of dust collection in the proposed dust collector, the centrifugal chamber is equipped with a static spinner installed on the outside of the fairing, the irrigator is located inside the fairing above the device for wet gas cleaning.

At the same time, the sprinkler is made in the form of a reservoir with a conical perforation (a single bottom, in the first part of which (a nozzle is installed. In addition, the device for a wet o icTKu gas is made in the form of a Ven-rury pipe). immersed in a liquid and a pyloroidal visor .- The drawing shows a longitudinal slit proposed by YaSheuLovitel. a fairing 5, inside of which an irrigator is installed, made in the form of a tank 6 with a conical perforated bottom 7, in the lower part of which is installed a nozzle 8. Under the conical bottom is the mouth of the tube E | , with a haloroidal visor 11. In the upper part of the body, the mouth / ano: is t & 12 "The device has a liquid level regulator 13, and a static twister 14 installed on the outer side of the fairing 5, Combined dust collector Tel sledukatsim working properly. The dusty air through the inlet 2 by the fairing 5 is fed to a static swirling device 14. Suspended particles under the action of centrifugal force. they are thrown to the walls of the casing and in the annular gap between the fairing 5 and the centrifugal chamber, they reach the highest speed, which makes it possible to concentrate the dust at the outer walls. Under the action of relative vacuum and the speed of movement during a turn, the air flow turns about 18O partly of dust by inertia continues to move in the same direction, then they are deposited and removed from chamber 4. Partly dehumidified air aiacases into the Venturi tube, passing through the water curtain, formed by the perforated conical bottom of the reservoir and the nozzle of the nozzle. Such an irrigator design allows the walls of the confuser and the neck of the pipe to be completely wetted. The main purpose of the Venturi tube is to ensure the high-turbulent nature of the air flow, that is, to prepare the gas for a deeper cleaning.

645684 And coagulate dust particles. Here the Origin | 1T is a partial capture of dust from the voe, the spirit, by drops of liquid. The moistened air at the outlet is encountered with a mirror of a liquid, leaving trapped on its surface and scattering by the drop of water. From the overpressure zone enclosed in the perforated cylinder 10, the air passes through the holes and water. The bubbling liquid from the space between the visor 11 and the cylinder 10 forms a gas-liquid foam, in which the final trapping of harmful impurities takes place. The working level of the liquid supplied to the sprayer under pressure and in the housing is maintained by means of the regulator 13. Purified air, passing through the droplet separator 12, is removed through the outlet nozzle 3 to the atmosphere. High efficiency in the proposed HOMI device is achieved several successively and jointly effective cleaning steps that are melting in it, interrelated with each other. Claim 1, Combined dust collector comprising a housing partly filled with liquid with inlet and outlet nozzles, a centrifugal chamber equipped with a fairing and a device for wet eyeglass located in the upper part of the housing; I by the fact that, in order to increase the dust collection efficiency, the centrifugal chamber is equipped with a static curler installed on the outside of the fairing, the irrigator is located inside the fairing above the device for wet gas cleaning , 2, Dust collector according to claim 1, about tl and h and y. u and with the fact that the sprinkler is made in the form of a tank with a conical perforated bottom, in the lower part of which the nozzle is installed. 3, The dust collector of claim 1, 1, of which the device for wet gas cleaning is made in the form of a Venturi tube; 4, the dust collector according to claim 1, 1, characterized in that the lower end of the diffuser of the Venturi tube is equipped perforated cylinder, immersed in a liquid, and polutoroidalny visor.
