Abstract

SUMMARY OF THE INVENTION: the device comprises a container in which a receiving chamber is installed with a tangential nozzle for introducing the mixture. The device is equipped with two fans rigidly connected to each other by a vertical axis, which is movably mounted on brackets fixed inside the receiving chamber. The fan blades are directed at an angle to the horizontal so that they create flows from the receiving chamber. The tangential branch pipe is located between the fans. 1 ill.

Description

The invention relates to a technique for separating a gas-liquid mixture and can be used in the oil, refining and petrochemical industries in gas-liquid separation processes.

The closest in technical essence is a device for separating gas from liquid, including a container in which there is a receiving chamber with a tangential nozzle for introducing the mixture with an annular truncated cone-shaped visor, to which an antifoam made with a central hole is attached, and reverse cone shaped lid. This device has limited capacity and does not use the energy of the falling liquid to improve the separation quality of the gas-liquid mixture.

The purpose of the invention is to increase the productivity of the device and the quality of separation.

The goal is achieved in that a device for separating gas from a liquid,

including a container in which a receiving chamber with a tangential mixture inlet pipe and a truncated annular truncated cone mounted to which a defoamer and a cone-shaped lid are attached is equipped with two fans rigidly connected to each other by a vertical axis located movably on the brackets, fixed inside the receiving chamber, and the fan blades are directed at an angle to the horizons, so that they create flows from the receiving chamber, and the tangential pipe is located between the fans tori.

The drawing schematically shows the proposed device.

The device comprises a horizontal cylindrical container 1, a nozzle 2 for introducing a gas-liquid mixture, a nozzle 3 for discharging gas, a nozzle 4 for discharging a liquid, a regulator 5 for liquid level, a receiving chamber 6 located inside the container 1, with a tangential nozzle 7 for introducing the mixture, an inner annular visor 8, installed in its upper part, the foam (L

carrier 9, attached to the visor, and a cover 10 mounted on the defoamer 9. In addition, the device is equipped with a lower 11 and upper 12 fans rigidly connected to each other by a vertical axis 13, which is movably mounted on the brackets 14 and 15, mounted inside the receiving chamber 6, and the blades of the fans 11 and 12 are directed so that during their rotation create flows from the receiving chamber. The tangential branch pipe 7 is located between the fans 11 and 12.

The device operates as follows: - The gas-liquid mixture coming from the pipeline or depulsator is fed through the nozzle 2 through the tangential pipe 7 of the inlet to the receiving chamber 6. The gas-liquid mixture falls on the blades of the fan 11 and causes it to rotate clockwise (rotation is shown in the drawing , view from above). Through the vertical axis 13, rotation is transmitted to 1 fan 12, which, due to the specific arrangement of the blades, creates a gas flow upward. Despite the action of the fans in countercurrent, the fan 11 will create more torque than the fan 12 due to the fact that the density of the gas-liquid mixture is higher below and, in addition, the gravitational forces of the incident liquid phase of the mixture act on the fan 11.

As a result, a zone of discharge is formed in zone A without spending additional energy, which contributes to the rapid and maximum (in quantitative terms) separation of the mixture into two phases - gas and liquid. The internal visor 8 prevents the ejection of liquid through the upper edge of the chamber and its entry onto the antifoam 9. The liquid flow passing through the receiving chamber 6 falls under the liquid level set by the level regulator 5 in the tank 1.

The gas separated from the liquid in the receiving chamber b passes through the antifoam 9 into the gas space of the container 1. In the antifoam 9, additional foam breaks down, because this work was initially carried out by the blades of the top fan No. 12, and the final cleaning of the gas from small drops of liquid. The liquid deposited therein continuously flows under the action of gravitational forces to the visor 8, thereby freeing up the working space of the antifoam 9 for the passage of the gas stream. Due to this, a film flows on the surface of the visor 8 along it, and then along the outer wall of the receiving chamber into the liquid zone of the device.

It should be noted that the proposed device has almost unlimited performance. The fact is that the more gas-liquid mixture enters the receiving chamber 6, the faster it rotates

the vertical axis 13, which means that the process of separating gas from liquid is more intensive.

The use of the proposed device will reduce the number of separators and, correspondingly, shut-off and control equipment, which will significantly reduce the cost of acquisition, installation and maintenance of equipment.
