Description

(54.) SEPARATOR (ITS OPTIONS)

The invention relates to a technique for the purification of gases and can be used for cleaning gases from droplets, as well as for wet cleaning of gases from dust and harmful gaseous impurities. Most preferred is the use of the invention as an oil separator for a crankcase ventilation system for automobile, diesel and marine internal combustion engines, as well as sulphonation systems, gas turbine engines.

The closest to the technical essence and the achieved result to the proposed is a separator comprising a cylindrical body, a lid, inlet, outlet and drainage patra & ki, a porous gasket laid on the bottom, a separating unit installed coaxially with the inlet pipe and made of corrugated elements, the input and output edges of which form the surface of the body of rotation 1J.

A disadvantage of the known separator is the need to make a separation unit from a larger number of flat and corrugated p-sheets, each of which should. set radially so o6pa3QM.j,

so that their input and output edges form a cylindrical surface. As a result, the manufacturing process of the separation unit involves a number of different operations: making flat and corrugated tapes of a given width, cutting them onto plates of a certain line, radial placement of the plates and fixing them (for example, by soldering) to the bottom and lid of the separating unit. This leads to an increase in the labor intensity and cost of manufacturing the oil separator, t which makes it difficult to master.

The purpose of the invention is to reduce the labor intensity and cost of manufacture.

This goal is achieved in that in a separator comprising a cylindrical body consisting of an upper part with

20 outlet pipe and bottom with inlet and drainage pipes, cover porous gasket, laid bottom, and the separation unit. Installed coaxially with the inlet pipe and

25 made of corrugated elements, the input and output edges of which form the surface of the body of rotation; the corrugated elements are made in the form of two porous ribbons:

30 on top of each other to form a helicoid with a step f equal to the height of the corrugations, with the longitudinal axes of the first and second belts arranged at an angle to the longitudinal axis, respectively, smaller and larger than 90. Moreover, the separator is equipped with a cylinder with gas windows attached to the lid body, while separating the node to be placed in the cylinder Р®. The goal can be achieved also by the fact that in the separator, including the case, cover, branch pipes, Porous packing, separating node of corrugated elements, the latter are made porous to Ring seals with radial corrugations, while the separator is equipped with flat porous rings placed between the corrugated elements. Corrugated elements and flat rings are made in the form of a truncated cone, and the corrugations are in the form of broken lines or smooth curves. FIG. Figure 1 shows the construction of a parator; in fig. 2 - corrugated mesh strips of separating knot rolled up in the form of a direct helix; in fig. 3 - flat and corrugated rings in the form of discs, made of a mesh, with the help of which a separating knot is performed; in fig. 4 flat and corrugated rings in the form of truncated cones; in fig. 5 - option of making corrugated rings of the apex of the corrugations of which has the form of a broken line with one break point; in fig. 6 is an embodiment of corrugated rings, the tops of corrugations of which have the shape of an arc of a circle. . The separator (Fig. 1) contains a cylindrical body, consisting of upper and lower parts 1 and 2, which are connected to each other by means of a thread. To prevent gas leaks, a rubber ring 3 is installed in the place of the threaded joint. An inlet 4 is attached to the lower part of the housing 2, the axis of which coincides with the axis of the housing. In the center of the conical bottom 5 of the lower part of the body there is a cylindrical projection b with a hole diameter equal to the inner diameter of the inlet nozzle 4. The outer diameter of the protrusion 6 is smaller than the inner diameter of the body 2, so that an annular depth 7 formed from the gas stream porous is formed in the bottom 5 gasket 8 (for example, a ring mesh package). In the same corner of the line 7, a drainage pipe 9 is attached to the bottom 5. A separating unit 10 is made of two corrugated tapes 11 and 12 (Fig. 2) made of the net of meshes, laid one on another and with a screwdriver so that they form a straight helicoid with a step equal to the height of the corrugation (Fig. 1). The tops of the corrugations of the tape 11 are inclined to its longitudinal axis at an angle of 60, and the tops of the corrugations of the tape 12 are inclined to its longitudinal axis at an angle of 120. As a result, the corrugated tapes 11 and 1.2 assembled form channels 13 of variable cross section for gas movement. Separating unit 10 is located inside a hollow cylinder 14, which is integral with the upper part of body 1. In the wall of cylinder 14 there are openings for the movement of purified gas. Between the cylinder 14 and the housing 1 there is a gap 15. To the lid of the upper part of the housing 1 an outlet nipple 16 is attached. The separating unit 1C can also be made of flat mesh, 17 corrugated mesh ends. made by punching in the form of discs (Fig. 3) or in the form of truncated cones (Fig. 4), while the tops of the corrugations 19 of the corrugated rings 18 can have the form of straight lines directed along the radii (Fig. 3) of broken lines with one break point (Fig. 5) and curved lines (circular arcs) with one inflection point (Fig. 6). The separator works as follows. The cleaned medium, for example crankcase gases, flows through the inlet 4 into the separating unit 10. Here, under the action of inertial forces, droplets of gas transported by gas are sown on the inlet edges of the channels 13 and 13 formed by corrugated ribbons 11 and 12 or flat and corrugated rings 17 and 18 Further deposition of droplets is carried out inside the channels 13 under the action of vortex, inertial and turbulent-inertial transfers. The planted droplets, merging with each other, form a film that, under the action of capillary forces, shrinks into the grid cells and the corners of the channels 13. The liquid film carried by the gas flow moves to the exit edges of the channels 13 and simultaneously flows through the grid cells into the annular recess 7 of the bottom. 5. Placement in the upper part of the annular recess 7 of the porous gasket 8 of finely meshed meshes prevents the entrained liquid from being carried by the gas stream. In addition, in the case of the use of a separator1), as the oil separator of the crankcase ventilation system of the internal combustion engines, the porous gasket 8 is a flame arrester. This contributes to improved engine reliability. In order to eliminate the disruption of oil droplets from the exit edges of the channels 13, it is necessary to choose the size of the windows in the cylinder column so that the gas velocity in the cross section of the windows does not exceed 4 m / s. The droplet-cleaned gas, PB, to the annular gap 15 goes to the pipe 16 and is discharged from the separator, and the trapped liquid is drained through the drainage pipe 9. Thus, the separating unit made of corrugated mesh tapes rolled up in the form of a helicoid. or from the flat and corrugated mesh rings, provides effective cleaning of gases from. drops. At the same time, the manufacture of the separating unit is greatly simplified by comparing with limestone structures, in particular, soldering or welding of small parts is excluded. This makes it possible to completely mechanize the manufacture of the proposed separator, which is especially important for large-scale production. Claims. 1 1.
