Description

This invention relates to a process for the separation of heterogeneous media and can be used in the chemical, microbiological and other related industries.

The aim of the invention is to intensify the process of separation of gas and liquid.

The drawing schematically shows a device for the separation of heterogeneous media.

The device includes a housing 1, a pipe 2 for supplying the mixture, a pipe 3 for discharging liquid, a fitting 4 for discharging gas. Inside the device, along its axis there is a mixture distributor in the form of a perforated pipe 5 with

conical plates b, the upper part 7 of the pipe 5 is made solid, and the upper end is provided with an annular element 8. The pipe 2 supplying the mixture is directed tangentially to the perforated pipe 6. Next to the perforated pipe 6, the gas outlet pipe 9 with holes 10 is located. Perforated pipe 6 in the lower part, it is plugged with a disk 11, to which is attached a cylindrical filtering element 12, made of a twill mesh network located along the height of the device between the housing 1 and the large bases of the package of conical plates ok 6. The principle of operation of the device is based on the use of the difference tight.

gas and liquid, as a result of which, when the liquid moves, gas bubbles are separated for estimates of centrifugal forces, gravitational forces, surface tension forces,

A device for separating heterogeneous media operates as follows.

The initial liquid containing the gas phase through the pipe 2 is tangentially supplied to the upper solid part 7 of the perforated pipe 5, twists and moves downwards. In a continuous area in the field of centrifugal forces of a swirling gas-liquid flow, the gas phase separates from the liquid, while the gas as a less dense phase collects at the axis of the perforated pipe 5 and is led through the central opening of the ring-shaped element 8 to the upper part of the device. In this way, a preliminary separation of the gas from the liquid is carried out. When fluid flows through the perforated pipe 5 and dispenses the flow through the orifices, liquid and gas are also separated, which is directed to the upper part of the device. Further, the liquid from the perforated pipe 5 is evenly distributed over the height of the package of conical plates 6, falling into the inter-articular space. As the fluid moves in the inter-tray space from the smaller bases of the conical plates to the larger bases, the gas phase also separates from the liquid, and the gas phase accumulates at the lower surfaces of the conical plates. The vapor tube 9 with openings 10 provides for a continuous discharge of the gas phase to the upper part of the device. Finally, the final separation of the gas phase from the liquid occurs on the inner surface of the cylindrical filter element 12 from the twill mesh network, and its warp threads are directed along its formers, where due to a sharp drop in the velocity of the liquid, gas bubbles are retained, enlarged and due to the difference in density between The gas phase float to the top of the device. The clarified liquid is directed to the lower part of the device and is discharged from it through nozzle 3. The gas phase is collected in the upper part of the device and is discharged through fitting 4,

Thus, the connection of the nozzle of the supply of phases tangentially with a continuous

part of the perforated pipe and supplying the upper end of the perforated pipe with an annular element forms the first zone of separation of gas and liquid.

The location of the perforated tube in the center of the device along its entire height at the smaller bases of the package of conical plates ensures a uniform flow of fluid into the inter-tray space,

thus forming a second separation zone for liquid and gas. The installation adjacent to the external side of the supply pipe of the vent pipe with openings ensures continuous removal of the gas phase from the inter-tray volume, which is the third zone of liquid-gas separation. The arrangement of the coaxially perforated tube in the gap between the casing and the package of conical plates of a cylindrical filter element made of a twill mesh network forms the fourth, final zone of separation of the gas phase from the liquid.

Thus, the set of design features of the proposed device provides for the creation in it of four consecutive zones of continuous separation of gas from the liquid during the movement of the latter, which generally allows

to intensify the process of gas separation from liquid without using external mechanical devices
