M.cl SOI D 45/06

MUCHER

The proposed train model relates to devices for separating droplet liquid from a gas-liquid stream and can be used in various industries.

Known kashgeovitel containing the housing of the pipe inlet and gas inlet, labyrinth channel with longitudinal walls, liquid traps facing the inlet to the stream (see application France JI2I97623 Mcl V01D 45/04, publ. 1974)

A disadvantage of the known droplet eliminator is the low intensity of droplet separation, a significant secondary droplet drop, which limits its use.

The closest known technical solution in its essence and the achieved result to the proposed one is a dust collector containing a housing with inlet and outlet nozzles for gas, a labyrinth channel formed by longitudinal walls in the form of semicircles, successively facing in different directions and containing slots with a guide plate for draining liquid , the free end of the plate is installed against the flow, and a means for removing liquid (see A.S. USSR Zh680271. M.cl.% 01D 45/06 publ. 1991.)

In the known device, a spiral trap, the cavity of which is in communication with the fluid collection chamber, serves as a means for removing liquid. The specified chamber is separated from the drop collection chamber by a vertical wall. However, the presence of spiral liquid traps and an additional partition significantly complicates the design and increases the intensity. At the same time, the required quality of gas purification is not ensured, since the film fluid is discharged into the slit only under the action of inertial forces, which is insufficient for intensive removal, therefore, a significant part of the liquid is re-sprayed by the stream.

The technical result achieved by using the proposed technical solution is the simplification of crushing, reducing material consumption and improving the quality of gas purification.

The technical result is achieved as follows: In a drop catcher containing a housing with inlet and outlet nozzles for gas, a labyrinth channel formed by longitudinal walls in the form of semicircles, sequentially facing different

sides and containing slots with a guide plate for the removal of liquid, containing

bones, the free end of the plate is set against the flow, and

to remove fluid, the plate is made in the form of a flange of the shell, and opposite the slots for draining the liquid, ejection slots with flanges are placed on the opposite wall, the free end of which is installed

In the direction of the gas movement, moreover, on the semicircle of the phadius on the outer part of the channel, plate-like liquid bumpers are installed.

The implementation of the guide plate in the form of a flanging of the slit for draining the liquid, placing opposite the slots for draining the liquid, on the opposite wall of the ejection slots with flanging, the free end of which is directed in the direction of the gas flow eliminates the complex design of the spiral trap, as well as the longitudinal partition, and by providing a suction of gas from the cavity of the housing to create an intensive suction of the film fluid from the inner part of the channel into its outer part.

The fastening of plate bumpers of the film fluid on a semicircle of a larger radius on the outer part of the channel eliminates the re-pickup of the film fluid through ejection slots into the channel.

in industry,

Figure 1 schematically depicts the proposed droplet eliminator

Figure 2 is a view of I-I

The droplet eliminator comprises a housing I with inlet and outlet nozzles 2 and 3 for gas, a labyrinth channel 4 and means for removing liquid. The labyrinth channel 4 is formed by longitudinal walls 5 and 6 in the form of semicircles, successively facing in different directions and provided with slots 7 for draining the film fluid with a guide plate in the form of a flanging 8 of the slit / the free end of which is oriented against the flow. Opposite the slots 7, ejection slots 9 with a flange 10 are placed on the opposite wall, the free end of which is directed along the flow direction. On the semicircles of a larger radius of the outer part of the channel 4, lamellar chippers of the II film liquid are strengthened. The lower part of the casing is equipped with erfKoerb / si 12 with an IS connection for collecting fluid and removing it from the casing.

Drop eliminator works as follows.

The exhaust gas with the droplet liquid is fed through the pipe 2 to the channel 4, where as a result of the action of centrifugal forces when the flow is turned, the droplet liquid is thrown onto the walls 5 and 6 of the channel 4 and moves along these walls in the form of a film along the stream. Reaching the entrance slit 7, the liquid film under the action of inertia enters this gap guided by flanging 8. Next, the liquid flows in the form of a film in a semicircle of a larger radius from the outer part of the channel 4. Reaching plates II, the liquid film breaks off the walls of the channel and merges into 12, from where the pipe 13 is removed from the housing.

During its movement inside the channel 4, the gas, due to the flushing of the flanging 10, ejects air through the slots 9 from the cavity of the housing, creating a vacuum in this cavity. Under the influence of this discharge, the film fluid directed into the slot 7 is sucked into it, which intensifies the drainage of the liquid and prevents repeated splashing. Slots 9 with flanges 10 are placed in places where there is no film liquid on the surface of the channel wall, therefore, re-spraying of the film; liquid and discharge (r. 10 does not occur.

The technical and economic efficiency of the proposed device is to simplify the design by eliminating complex spiral-shaped traps, due to the implementation of slots with flanges, some of which suck the film fluid, spine, and the second ejects air from the body cavity, creating a vacuum in it. This eliminates the need for an additional vertical wall to form a chamber for collecting liquid, because in the proposed device, the liquid flows directly along the outer part of the channel. At the same time, the material consumption is reduced and at the same time the quality of gas purification is improved due to the prevention of repeated spraying.
