Description

The utility model is designed to capture fine and aerosol liquid and solid particles from a gas stream, and is used in the oil, gas, chemical and other industries.

A large number of vertical separation bags are known, consisting of overlapping curved plates forming slotted channels in the overlapping zone and fixed to the top and bottom to the covers. These separation bags are known, for example, from the descriptions of patents for inventions No. 2221625 (IPC 7 B01D 45/12, 2004 [1]), No. 2244584 (IPC 7 B01D 45/12, 2005 [2]), No. 2287357 (IPC B01D 45/12, 2006 [3]), No. 2304455 (IPC B01D 45/12, 2007 [4]), and descriptions of patents for utility models 52574 (IPC B01D 45/12, 2006 [5]), No. 55301 (IPC B01D 45/02, 2006 [6]).

A common disadvantage of these separation packages is the simply connected surfaces of the separation plates. When using these separation bags, a relatively large portion of the liquid moves along the edges of the separation plates at the exit of the slotted channels. However, in these areas, the flow exiting from the slotted channels expands, which leads to the spraying of a certain amount of liquid from the edges of the separation plates.

The technical result provided by the claimed utility model is to increase the efficiency of the separation package.

The essence of the utility model is that the vertical separation package of a cylindrical shape contains vertical curved separation plates located in its forming surface, mounted on top of an annular top cover with an outlet. In this case, the separation plates are placed relative to each other with a partial overlap, and form identical, constant-size slotted channels in the overlap zone. In the area of the slotted channels in the separation plates, through holes are made. Moreover, in adjacent separation plates forming one slotted channel, these holes are located opposite each other.

The holes of the separation plates horizontally are located mainly in the center of the slotted channels. These holes are made

preferably round. It is possible to make said openings of a rectangular shape with a long side arranged vertically. It is permissible to place two holes in the upper part of the plates, and two in the lower. It is possible to arrange two holes in the upper part of the plates, two in the middle part, and two in the lower part. It is also possible to arrange four holes along each vertical edge of each plate.

The essence of the utility model is illustrated by the following graphic materials.

The figure 1 shows the appearance of the separation package vertical; figure 2 is a cross-sectional view of the separation package (section aa of figure 1); figure 3 is a view B of figure 2, enlarged; figure 4 is a side view of the separation plate of example 1; figure 5 is a side view of the separation plate of example 2; figure 6 is a side view of the separation plate of example 3; 7 is a side view of the separation plate of example 4.

The vertical separation bag (FIG. 1) is cylindrical in shape and contains vertical curved separation plates 1 located on its forming surface. These plates 1 are placed relative to each other with partial overlap and form identical, constant-size slotted channels 2 (FIG. .2). On top of the plate 1 is fixed to the annular upper cover 3 with the outlet 4, and from the bottom to the bottom cover (not shown).

In the area of the slotted channels 2 in the separation plates 1, through holes 5 are made (Fig. 3). In adjacent separation plates 1, forming one slotted channel 2, these holes 5 are located opposite each other. Horizontal holes 5 are located mainly in the center of the slotted channels 2.

Examples of specific performance.

Example 1

The holes 5 of the separation plates 1 are made round (figure 4). Two holes 5 are located at the top of the plates 2, and two at the bottom. Moreover, each plate 1 contains four holes.

Example 2

The holes 5 of the separation plates 1 are made rectangular, with a long side placed vertically (figure 5). Two holes 5 are located at the top of the plates 1, and two at the bottom. In addition, each plate 1

contains four holes.

Example 3

The holes 5 of the separation plates 1 are made round (Fig.6). Two holes 5 are located in the upper part of the plates 1, two in the middle part, and two in the lower part. Moreover, each plate 1 contains six holes 5.

Example 4

The holes 5 of the separation plates 1 are made round (Fig.7). Four holes 5 are placed along each vertical edge of each plate 1. Each plate 1 contains eight holes 5.

The implementation of the structural elements of the claimed utility model is not limited to the above examples.

The vertical separation package, placed in the center of the vertical vortex flow, works as follows.

Due to the pressure difference in the center of the vortex flow and on its periphery, particles of gas, liquid and small solid impurities fall on the outer surface of the separation plates 1, and are transported by the gas stream through the slotted channels 2, on their inner surface.

In this case, the liquid particles and the small particles of solid impurities moistened with them coagulate on the surface of the separation plates 1 and, due to the surface tension forces, are held in the regions of rupture (incoherence) of the separation plates 1. These areas are the holes 5 in the separation plates 1 located in the slotted channels 2. Due to the fact that these holes 5 are located inside the slotted channels 2, that is, where the flow uniformity is higher, the spraying of liquid particles into the gas stream, i.e., the secondary ablation of liquid awns.

With an increase in the mass of liquid accumulated in the holes 5 of the separation plates 1, above a critical value, when the gravity becomes greater than the surface tension force, the liquid “breaks off” and moves downward along the surface of the separation plates 1.

Due to the location of the holes 5 in the separation plates 1 opposite each other, coagulation in them occurs together, which increases the numerical value of the aforementioned critical mass. In this case, initially the liquid accumulates at each hole 5 separately, and then, when the surfaces of the liquids come into contact, together. Moreover, at the moment of contact, the volumes of accumulated liquids are combined, which leads to a reduction

total surface, and therefore - to increase the surface tension force. This leads to an increase in the critical mass at which a “drop” of a liquid drop from the holes in the separation plates occurs.

Having reached the lower edge of the separation plates 1, the liquid slides from them and is drawn down from the separation package.

The purified gas flows up to the outlet of the separation bag.

Thus, from the foregoing, it follows that in the claimed vertical separation package, the claimed technical result: “increasing the efficiency of the separation package” is achieved due to the fact that the vertical separation package of a cylindrical shape contains vertical curved separation plates located in its forming surface, fixed from above to the annular upper cover with outlet. In this case, the separation plates are placed relative to each other with a partial overlap, and form identical, constant-size slotted channels in the overlap zone. At the same time, through holes are made in the area of the slotted channels in the separation plates. In adjacent separation plates forming one slotted channel, said openings are located opposite each other. In this case, a decrease in the amount of liquid moving along the edges of the separation plates when using the separation package is due to the fact that most of the liquid coagulates at the holes of the separation plates located opposite each other inside the slotted channels.

The inventive separation vertical package is implemented from industrially produced materials, can be manufactured at any engineering company.
