Description

The invention eliminates the wet scrubbing of gases from suspended solids.

The purpose of the invention is to increase the efficiency of gas cleaning due to the mechanical disruption of gas bubbles before entering the contact tube.

FIG. 1 shows the device, a general view; in fig. 2 is a section A-A in FIG. ; in fig. 3 is a section BB in FIG. 2; in fig. 4 - section bb in. one.

The wet dust collector comprises a housing 1 with a contact chamber bounded by a Kolnachkov plate 2, a main disk 3 and a full disk 4, a contact tube 5, a device 6 for centrifugal phase separation and a separation chamber 7.

The contact tube 5 is made with vertical non-temporality to change the volume of chamber 1. The co / wheelbarrow 2 is installed above the inlet nozzle 8, the contact chamber is filled with liquid through the nozzle 9, and the outlet nozzle 10 is located in the upper part of the recovery chamber 7.

The pipe 5 is installed coaxially with the contact chamber, and the disk 4 is placed in front of the entrance pipe 5. The device 6 is used for intermittent separation of in-situ phases at the outlet end of pipe 5 and is made in the form of a pin 11 (FIG. 4) with profiled blades 12 .

The recovery chamber 7 is equipped with a slurry drainage rod 13.

The entrance of the pipe 5 is provided with an annular cavity with an upper wall in the form of a disk 3, the lower one in the form of radial plates 14 installed at an angle to the horizontal with partial overlapping with each other to form slotted channels 15. The side walls of the cavity are formed by walls contact chamber and N-N lemeHHEjiMH between the disk 4 and the inlet end of the pipe 5 vertical plates 16 installed at an acute angle to the circumference of the pipe with the formation of slots 17.

On radial bases 14, exchange; mobile nozzle 18, for example, from spherical elements.

It is advisable that the perimeter of the disk 4 and the radial plates 14 were ukrey

Additional vertical plastics 19 at an acute angle to the generator.

It is advisable to make the elements E of an unloading 8 differently: shknmi with quarters 2–3 times in diameter.

The device works as follows.

For 1 liter of gas, through gas nozzle 8 enters the column plate 2, from where it breaks out at an increased rate, disperses in the liquid and rises as a gas-liquid mixture upwards. Achieving radial and 14-type and disk 4, the gas-liquid mixture under conditions of constrained bubbling touches its CTCIJOK and the gas bubbles 5 will collapse from contact, releasing HbiJib, which binds to the liquid.

The gas-liquid mixture moves at a sufficiently high speed through the channels 15 and causes the nozzle 18 to rotate.

During the rotation of the nozzle 18,

leaping from oblique radialia gctastine 14, cobalt at height, and vigorously collide with each other, the palipine on them is 1 aza, and the simultaneous iiepecKaKHBatnie of these e. In the case of landfills, 16 tonnes of loss causes their oscillations in the normal direction, which will increase the frequency of collision and, accordingly, increase the intensity of the destruction of gas bubbles, najinriinnx, by 1 step of mobile and 1 mobile elements.

0 In the case of a nlastip installation, 19, against the walls of the contact chamber, the elements of the nozzle 18, skipping over the plates 19 and 16. oscillate in a mutually opposing manner, that the impact of their collisions between them will improve and improve the conditions for bonding the dust particles - costo.

The gas-liquid mixture, rising along the contact tube 5 through the slots 17 and subjected to the best treatment, falls into

0 a phase separation device 6, where it is subjected to turbulence by blades 12. On the inside surface of the cap 11, a fluid flow is formed with bound particles and dust, which is thrown downwards by centrifugal forces to the bottom of the separator chamber 7 and discharged to the sludge discharge fitting 13. Liberated as a result collisions against the wall of the cap 11 and the blade 12, the gas ul. is aliated through the outlet fitting 10.
