(54) DEVICE FOR DEGASING LIQUID

one

The invention relates to a device for degassing a liquid and can be used, for example, in the non-industrial industry for separating gas from oil.

A device for degassing a liquid is known, which includes a tank with onlets for introducing a gas-liquid mixture and withdrawing a liquid and a gas, a rotor immersed in a liquid, and turbulence dampers in a heat recovery tank 1.

The presence of a layer of liquid over the rotor, through which gas bubbles rise, and the contact of the IC with the surface-absorbing turbulence contributes to the condensation of the released gas, which reduces the quality of degassing.

The closest in technical essence and the achieved result is a device for degassing a liquid, comprising a housing with a gas-liquid mixture supply nozzle and a rotor with a turbine mounted along the axis of the housing above the liquid 2

A disadvantage of the known device is the insufficient quality of degassing, due to the fact that the rotor design does not contribute to the appearance of cavitation in a liquid.

The aim of the invention is to improve the quality of degassing.

For this purpose, the device is equipped with reagents radially fixed on the lateral surface of the rotor and made of a turbo .Izuyuzuyu | their elements, and the pipe supplying the liquid-liquid mixture is installed tangentially on the lateral surface of the casing on the opposite of the rotor turbine.

FIG. 1 shows the proposed device; in fig. 2 is a section A-A in FIG. one; in fig. 3 - section of the turbo-guiding elements, embodiments.

The device includes a housing 1, a tangential nozzle 2 for supplying a gas-liquid mixture, a turbine 3, a rotor 4 with an NUI grille 5. made of turbulent elements 6, a droplet separator 7 in the form of an impeller, a gas discharge disk 8 with an opening, a conical drain 9, a liquid outlet 10 and a spout 11 gas outlet. The turbulizing elements can be made, for example, in the form of a cylinder, a hellintic cylinder, etc. The device works as follows The gas-liquid mixture through the tangential nozzle 2 enters the housing 1. Moving in the near-wall region of the apparatus, the gas-liquid flow enters the turbine blades 3, and under the action of the circumferential component of the flow, the turbine, together with the rotor 4 and the droplet separator 7, acquires a rotational motion. Under the action of gravitational forces, the mixture from the interscapular channels of the turbine moves along the step of the body in the axial direction into the zone of the turbulizing elements 6, while maintaining rotational motion, which is further supported by the turbulizing elements in the whole area of their operation. Due to the presence of friction forces between the fluid and the walls of the body and the internal friction forces of the fluid due to viscosity, the velocity of the mixture becomes less than the speed of the elements 6 in contact with it, which causes them to flow around and form cavitation zones. In this case, in the cavitation zones, gas is released, the union of small gas bubbles into larger ones and their transition under the action of centrifugal forces into the gas zone of the device. The liquid, leaving the area of action of the elements 6, flows down the conical drain 9 into the lower part of the device, from where it is removed through the nozzle 10. The gas from the gas zone passes through the opening of the exhaust gas disc 8, the droplet separator 7 and is removed through the outlet nozzle 11. As it passes through a drop catcher drops of a liquid contained in a gas, when meeting with the surfaces of the blades of the impeller, form a film of liquid, which is thrown by the centrifugal forces to the periphery and along the upper PLANE of the flue gas disc part of the device. Equipping the rotor with lattices with elements 6 and placing it above the liquid level makes it possible to create a large number of cavitation zones in a thin layer of liquid distributed along the inner side surface of the liquid body in the absence of hydrostatic pressure. Cavitational zones are formed in the stern region of the elements of 6, for example cylinders. Since the cavitation zones move after the elements 6, they repeatedly cover the entire separated liquid during its movement along the wall of the device from the entrance to the liquid level. The invention provides a device for degassing a liquid, comprising a housing with a gas-liquid mixture supply nozzle and a rotor with a turbine mounted along the axis of the housing above the liquid, characterized in that, in order to improve the quality of degassing, the device is equipped with lattices radially fixed on the lateral surface of the rotor and made of turbulizing elements, and the gas-liquid mixture supply nozzle is installed tangentially on the side surface of the housing opposite the rotor turbine.
