Description

The invention relates to mass transfer technology and can be used in chemical, petrochemical, as well as other industrial processes, during the processing stage of soiled basins.

The purpose of the invention is to increase the degree of gas purification, simplify the design of the apparatus and reduce energy consumption.

Figure 1 shows a diagram of the proposed apparatus, a longitudinal section on figG2 - section A-A in figure 1; fig.Z - node I in figure 1; in Fig. A, node II in Fig. 1.

The apparatus includes a housing 1 with an inlet nozzle 2, a vortex chamber 3 with guide vanes 4 around the perimeter and a sprinkler 5, a separation chamber 6 with a rotor sprinkler 7, and an outlet nozzle 8. The inlet nozzle 2 is attached tangentially to the side wall of the housing 1.

Swirl chamber 3 is fixed on

partition 9 in the form of a truncated con

sa

The rotor splash guard 7 is mounted in the form of a cylinder 10 with a horizontal disk 11 with blades 12, discharge tubes 13 mounted above the disk and plates 14 located on the outer surface of the cylinder 10 in its lower part.

A nozzle 8 is fixed under the disc 11 with a gap. At the bottom of the casing between its wall and the cylinder 10 a shell 15 is fastened with the formation of an annular pocket 16.

The spray separator 7 is connected to the lower end of the shaft 17 “attached to the upper part of the housing on bearings. The blades 12 of the splash separator 7 are placed in the cavity of the vortex chamber 0 The plates 14 of the rotating spray separator 7 gas are swirled in the rim of the separation chamber, while the liquid in the form of

3, and the guide vanes 4 of the vortex chamber are hollowed out of the stencil drops hollowed from the walls with perforations 18. The gulls 15 flow down the bottom of the apparatus

An annular tray 19 Q is attached to the blades 4 in the upper part by a spray liquid, which communicates with the cavities of the blades through the holes 20.

It is advisable that the blades 12 of the splash separator 7 were set inclined in the radial direction

50

and is discharged through port 24.

The cleaned gas passes through the gap formed by the disk 11 and the nozzle 8, and is directed through the specified nozzle for further processing or is emitted into the atmosphere.

In the case of operation of the apparatus according to the recirculation mode of the liquid and the discharge of the 55 blades 12, inclined and hollow when the latter is rotated, the fluid located on the disk 1 is sucked into the plate 21 under the action of centrifugal

Aside. The horn 4 of the vortex chamber 3 is hollow with a suction port 2.1 at the disk 1 1 and the outlet holes 22 on the side of the blades 4 of the vortex chamber.

The lower part of the housing 1 is equipped with nozzles 23 and 24 for draining the waste liquid.

Above tray 19, the tube is reinforced

25 for feeding zkidkosti.

The device works as follows.

The treated gas enters through the tangential pipe 2 inside

hull, passes between the shoulder blades 4, additionally whirl in the direction of the central part. The irrigating fluid under the action of the hydrostatic column and ejected through the perforations 18 by the flow of gas passing between the blades 4 is picked up, intensively moving with gas vortices and in the form of a gas-liquid mixture strikes the blades 12 of the spray separator

7, is additionally dispersed with the formation of a rotated foam layer, where the main process of mass exchange between gas and liquid takes place. At the same time, the rarcr studied the splash-pools and the streams of the components entering chamber 3, after contact. the gas-liquid mixture is forced out of the vortex chamber and out through

hole in the bottom of the camera.

Getting into the separation chamber 6, the descending vortices of gas and liquid, have a certain amount of movement, additionally

spin the rotor of the splash separator 7. From the upper part of the cylinder 10, the liquid flows through the tubes I3 into the annular pocket 16, from where it is removed via the nozzle 23 from the apparatus.

The plates 14 of the rotating spray separator 7 gas are connected to a swirling motion in the spherical part of the separation compartment, while the liquid in the form of

drops are dropped on the wall of the casing 15, flows down the bottom of the apparatus

and is discharged through port 24.

The purified gas passes through the gap formed by the disk 11 and the nozzle 8, and is directed through the specified nozzle for further processing or is emitted into the atmosphere.

In the case of operation of the apparatus according to the mode of recirculation of the liquid and the filling of the blades 12, inclined and hollow when the latter rotates, the liquid on the disk 1 is sucked into the hole 21 under the action of centrifugal force.

These forces rise up the entire length of the blades and are ejected into the apertures 22, where they are picked up by the flow of a gas-liquid mixture and dispersed in the vortex chamber. The fluid is lifted along the cavity of the blades 12 due to the fact that at the same angular velocity of the upper and lower portions of the blades 12, due to tilting outwardly from the axis of rotation, the circumferential speed of their upper part is higher than the circumferential speed of the lower ,. therefore, the centrifugal forces acting on the fluid in the upper part of the blades are higher than in the lower part, and that 5 creates a subsampling of the fluid below Bfiepx.

The advantages of the proposed apparatus are to increase the degree of gas cleaning to 20-25% by increasing the dispersion of the liquid in the gas due to the collision of the gas-liquid mixture with the spatter separator blades as they leave the vortex chamber blades towards its central part. This leads to increased turbulization and intensity of interaction between the renewed surfaces of the phases.

Due to the direct placement of the bottom of the hull in the irrigation zone, which further simplifies the device and reduces energy consumption.

Neither the blades of the splash separator in the stream in the form of an annular tray, the mounting of the gas applied to the treatment increases the speed of rotation of the splash separator and improves the separation conditions, which reduces the spray splash by 1.21, 3 times. Due to the exclusion of the drive 35 N and the fact that the blades of the spraying of the tubes for supplying the spray liquid (the electric motor and the gearbox) simplify the design of the apparatus and reduce the energy consumption by up to 50-60%.

By supplying the used liquid to the bone with the inclined blades of the splash separators, there is no need for an additional pump to feed the used liquid from

bottom of the hull in the irrigation zone, which further simplifies the device and reduces energy consumption.
