Abstract

The invention relates to devices for the wet cleaning of gases from dust, can be used for carrying out the processes of dedusting and absorption and allows to increase the cleaning efficiency. The device comprises a housing 1 divided by partitions 2 into chambers of the contaminated and clean gas chamber. A channel 9 of confused-diffuser section, formed by two zigzag perforated walls 10, is placed in the chamber of purified gas. In the lower part of the channel, at the liquid level, there is a guide element, made in the form of an angle 12, pointing upwards. The presence of the channel provides alternate compression and expansion of the flow, which increases the intensity of mass transfer and improves the conditions of gas cleaning, and the installation of the guide element prevents counter-impact of the flows and at the same time allows you to adjust the capture of fluid and its removal into the channel. The shelves 13 of the guide element are pivotally interconnected with the possibility of rotation in mutually opposite directions, and the curved plates 4 are made perforated. 2 hp ff., 3 ill. o (L 12 J9 co 4; O 00 o co l

Description

The invention relates to devices for the wet scrubbing of gases from solid aerosols (dust) and p-ars of harmful substances and can be used in various sectors of the national economy for carrying out dust collection and absorption processes.

The purpose of the invention is to increase the efficiency of gas cleaning.

FIG. 1 shows a diagram of the proposed device, a general view; in fig. 2 -

Next, the gas-liquid flow enters the channel 9, where during its movement it experiences alternate compression and expansion, which increases the intensity of the exchange of phases and contributes to the effective removal of impurities from the gas. As it moves along channel 9, part of the gas through the perforations of the walls 10 rushes into the zone between the plates 4, the passage through the liquid film formed on the perforations of the flow-through pipe 6 in the upper part of the body. Case 1 is divided by vertical partitions 2 into polluted chambers 7 and clean gas chamber 8, in which Usta 9 is formed by two side zigzag perforated walls 10 and a confusion-diffuser section is made. The plates 4 are made perusel I in FIG. one; in fig. 3 - section Yunok 10. Liquid film in the narrowed part

AA in FIG. 2. The channel is picked up by the aspirated flow. The device contains partially a gas-liquid mixture with an external liquid housing 1 with vertical channels of the channel into its internal part, partitions 2 with inclined trays 3, since in the narrowed part of the channel the contact elements are curved plastic vacuum is present. This also contributes to a 4, 1 / -shaped guide 5 and to the intensification of the exchange of phases and improvement

gas cleaning conditions.

By rotating the shaft 15 with the hand 17 through the levers 16, the angle of inclination of the shelves of the angle 12 can be changed, which allows the plates 4 to be adjusted, facing the convex of the liquid film thickness, by hooks to the outlet nozzle 6.turned by the gas flow, speed moving this film and spraying it in a stream. By changing the angle of the shelves of the corner, you can achieve the optimum mode of operation of the device. In the case of plates 4

fortified and connected to the diffuser 25 perforated part of the flow of gas-liquid-part of the channel. The inclined trays 3 of the cross-phase will intersect the indicated ones concave and are connected to the inlet plate through their perforations, which by the extra-flume part of the channel 9. Under the channel 9 will increase the contact of the fluid with at the level of the liquid fixed to the torzo-gas.

vym the walls 11 of the guide element in the gas-liquid mixture plates 4 and

a corner 12 with concave flanges 13 of the Y-shaped guide 5 is rejected and apex upwards. on the vertical partitions 2, it flows down

The shelves of the corner 12 are pivotally connected to it and to the chutes, where they are partially under the top again and equipped with a stream, and part of it flows down, the house 14 turns into mutually counter-purified gas containing particles

positive directions. The actuator 14 is made out of liquid, passes through the droplet separator 18, in the form of being fixed on the walls 11, where it is released from the dropping liquid and 5 with the levers 16 and the handle 17. In the lower direction it is directed to the consumer or removed in it set regulation - atmosphere.

the liquid level torus 18 and, in the upper so, the installation directs the juicer catcher 19. The upper parts of the chamber 7 of the tampering element prevents the counterhead are provided with inlet nozzles 20, and the bottom 40 Avoidance of the streams and at the same time allows the case to be equipped with a socket 21 fluid and taking it out

the channel between the plates with increased kinetic energy of the flow, and the formation of the channel by the perforated zigzag walls of the confuser-diffuser

nick), enters the casing 1 of the cross-section device, provides alternate compression of the cut inlet pipes 20, passes the chambers and the flow broadening, which increases the intensity of mass transfer and improves the gas cleaning conditions.

sludge

The device works as follows.

The contaminated gas is divided into two streams (for example, in a ventilating three-gas 7 to the liquid, then into the gap between the liquid surface and the trays 3 rushes to the central part of the device, capturing part of the liquid and in the form of a film, moving it to the top of the corner 12 along its shelves. Since the gas flow smoothly changes its direction of movement due to the concavity of the trays 3 and the shelves of the corner 12 and meets another flow at an acute angle, the kinetic energy of the flow is almost not lost, and the film supply of the liquid along the shelves Golka conditions raises product spraying liquid into the gas stream.
