Description

t

The invention relates to the purification of gases and liquids from suspended particles and can be used in various industries.

A device for fine gas cleaning is known, comprising a housing with inlet and outlet nozzles and a lid, as well as blkk porous cartridges suspended from a tube plate with the possibility of removing U1.

Also known filter for cleaning gases, comprising a housing with a cassette filter element mounted on the shaft, a regenerating device and an actuator. The housing is provided with radial partitions dividing it into filter, sluice and regeneration chambers, and the cassette filter elements are installed radially and are in the form of rods with a diameter decreasing to the axis of the building. Sa C2.

However, these filters are bulky, require compressed air for regeneration and do not have the ability to self-clean. In addition, the existing rods are used as a basis for winding the filter material and not directly participating in dynamic cleaning of the medium and self-cleaning.

The closest technical

10 of the essence and the achieved result is an installation comprising a housing with an inlet pipe and outlet pipes of separated fractions coaxially mounted

IS inside the centrifuge housing, the rotor of which is made of a set of vertical rods 131.

The disadvantage of the known installation is the impossibility of self-cleaning of the rotor

20 centrifuges.

The purpose of the invention is to increase the efficiency of the installation by ensuring its self-cleaning.

The goal is achieved by the fact that in an installation comprising a housing with an inlet pipe and outlet pipes of separated fractions, a centrifuge coaxially mounted inside the housing, the rotor of which is made of a set of vertical rods, is equipped with ring centrifuges. guides, and the rods are supplied with spring shells and installed in two rows in annular guiding centrifuges with the ability to move under the action of the treated stream.

Not figs, presents an installation for the purification of gases and liquids from mechanical impurities, a general view; Fig 2 shows a section in Fig.1.

The installation includes a housing - a cyclone 1 with a lid 2, a centrifuge 3, the rotor of which acts as a filter, drives the centrifuge k, the device

5 sludge outlet, with the centrifuge rotor made of two layers of rods

6 and the rods are provided with spring shells 7, a reflector 8, in which the outlet 9 of the centrifuge 3 is inserted axially through the bearing, the second end of which is through the shaft 10

and the bearing in the bottom of the housing 1 is connected to the drive 4. Drives with variable speed are used as a drive: step change (gearboxes) and smooth (thyristor), Rods 6 with ends are located in annular guides 11 of centrifuge 3 and, due to spring shells 7, have gaps between themselves/

The installation works as follows.

Gas or liquid is fed tangentially into the housing - cyclone 1 and twisted under the action of the centrifugal forces of the cyclone. The heaviest particles fall out at the walls of the housing 1 and the second purification stage is carried out by filtering through the layer of rods 6p, throwing particles along the radius during rotation, from where they fall down

under the force of gravity. In this case, the spring shells 7 of the rods 6 create the necessary clearance for the passage of the purified medium. Centrifuge rotor

3 is cleared automatically. Complete removal of sediment from the central part of the rotor is carried out through the output device 5, which opens when the jet direction changes,

what is achieved by external switching, namely, by switching the flow of the medium: to the output - pressure, and to the input - suction.

Thus, the proposed installation for cleaning gases and liquids from mechanical impurities, combining the principle of operation of a cyclone and a centrifuge, provides a two-stage cleaning, compact and simple.

in operation.
