Description

Technical field

The present invention relates to a device for separating streams for the production of bitumen and other high-viscosity products in the petrochemical, petrochemical and other industries. Areas of industry.

BACKGROUND OF THE INVENTION

No such devices are known for separating flows into reactors in bitumen production.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide flow separation in bitumen reactors to create oxidation reaction conditions at different rates at the top and bottom of the reactor to produce products of different chemical composition in these zones.

The purpose was achieved by creating a separation device comprising at least two sieve plates spaced at a certain distance from each other. Between the plates are tubular cylindrical elements arranged chaotically in at least one layer with the possibility of vertical movement.

It is appropriate that the tubular cylindrical elements be constructed as solid cylinders and / or hollow cylinders, and / or hollow perforated cylinders and / or screw metal bands.

In one embodiment of the separating device, at least one of the sieve plates is made of a support to which a perforated plate is attached, the perforation being made so that openings are provided at a certain distance from each other, whereby the walls of the apertures are angled at the plane of the plate.

In this embodiment, the apertures * openings may * have a * rectangular, circular, elliptical, S-shaped cross section, ....

It is advisable that the walls of the apertures be located on either side of the perforated plate.

The advantages of the separation device according to the invention are to ensure efficient separation of the individual zones into a single reactor, while at the same time not disrupting the technological process unity by the height of the reactor at different process velocities in the different zones.

Examples of specific implementation

The separation device (Fig. 1) includes at least two sieve plates 1, spaced a certain distance from each other. Between the plates 1 are placed tubular elements 2, arranged randomly (best illustrated in Fig. 2) in at least one layer with the possibility of vertical movement. It can be seen from FIG. 5, the tubular cylindrical elements 2 may be constructed as solid cylinders, hollow cylinders, perforated hollow cylinders or screw metal bands. The latter variant embodiment has a number of advantages with respect to the effect of

The screw-like metal thickness of the strip, as well as the different pitch of the screw, these bands may parameters depend on the rate of flow of the oxidizing gas and the lifting force that allows the elements 2 to be in motion.

The switchgear may also comprise more than two trays (Fig. 3), with tubular members 2 placed between each two sieve trays 1.

The number of tubular elements may vary depending on the desired layer density of such chaotic elements. Thus, a different leakage rate of the separation device can be achieved, including up to complete separation of the zones in the reactor.

In principle, known mesh tray designs may be used in the separation structure described above. Particular advantages with respect to maintaining the uniformity of the process height in the reactor are the use of the specific design of the sieve tray shown in FIG. 4. The plate shown in this figure includes a support 3 on which a metal plate 4 is attached with perforated through holes 5 spaced apart. The cross-section of these openings can be varied. It is appropriate to form the openings 5 with an S-shaped cross-section to give an S-shaped profile on the wall 6 of the opening. The perforation of the plate 4 is made so that the wall 6 of the through hole 5 is angled with respect to the gap A of the plate 4.

Attachment of the described separation device to the reactor walls is accomplished by known methods (welding, screws, etc.).

The action of the separation device according to the invention is as follows:

On the upper side of the separator £ Yours has missed the oxidized bitumen, reducing the velocity and amount of fluid passing through the device due to the presence of chaotic tubular elements 2. At the same time, oxidizing fluid is passed from the lower side of the separating device (e.g. air), under which the elements 2 begin to "float" in the gap between the two sieve plates 1. The movement of the elements 2 changes the rate of flow of the oxidized bitumen through the sections. the net device. Thus, by changing the velocity of the oxidizing fluid and choosing the density of arrangement of the tubular elements, the desired rate of flow of the oxidized bitumen through the separation device is achieved.
