The device comprises a horizontal body 1, an inlet 2 with a collector 3 of the gas-liquid mixture inlet, on the side surfaces of which there are slots 4 in which guide vanes 5 are installed at an angle of 30-50 ° C. to their plane towards the inlet nozzle, and in addition, the guide vanes are inclined in a vertical plane at an acute angle against the flow and made protruding beyond the dimensions of the collector. The blades are made in the form of trapezoids, the larger base of which is located inside the body. An airtight wall can be fixed on the vertical ends of the blades or on the upper and lower ends. 4 hp ff, 3 ill.

Description

The invention relates to the purification of gases from liquids, mainly with plug flow of a liquid in a gas stream, and can be used in the oil, gas and other industries.

The aim of the invention is to increase the efficiency of separation of liquid from gas by eliminating the vortex and wave formation and spray.

Figure 1 shows a device for separating liquid from gas, General view; figure 2 is a section aa in figure 1; in Fig.3 - view B in Fig.2 (in the embodiment of the guide vanes in the form of trapezoid).

A device for separating liquid from gas contains a housing 1, an inlet pipe 2 with a manifold 3 for injecting a gas-liquid mixture, on the side surfaces of which there are slots 4 with guide vanes 5 installed therein at an angle of 3050 ° to the plane of the slots 4 and towards the inlet pipe 2, while they are inclined in a vertical plane at an acute angle against the flow and protrude inside the housing 1 beyond the side surfaces of the collector. At the ends of the blades 5 located inside the housing 1, sealed walls 6 and 7 are fixed (Fig. 2,3). Walls 6 are installed on the vertical ends of the blades, walls 7 - on the upper and lower ends. The device is also equipped with a drop eliminator 8, a nozzle 9 for the outlet of the purified gas installed behind it, and a nozzle 10 for the exit of liquid.

The device operates as follows.

A fluid plug moving in a gas stream at a speed of 40 m / s, through the inlet 2 enters the manifold 3, then - on the guide vanes 5, each of which brakes and diverts a part of the fluid plug in the inclined scapular channels. The kinetic energy of individual jets is extinguished in the channels, and the liquid, without crushing and not splashing, flows down the inclined blades.

In the final stage of receiving the liquid plug, i.e. with a jump-like gas rush, and, as a result, a jump-like change in the gas-liquid mixture velocity, when the latter passes through the interscapular channels, the energy is quenched, the velocity field of the individual jets is equalized, which prevents vortex and wave formation and splashing.

If the device has sealed walls 6 or 7, immiscible gas and liquid flow are formed in each jet of gas-liquid mixture passing through the interscapular channel. In this case, in the presence of wall 6, countercurrent upward gas flow and downward fluid flow are formed, and in the presence of sealed walls 7, direct-flow, upward and downward flowing gas and liquid flows are formed, respectively. Next, the gas, having passed the droplet eliminator 8, is discharged from the housing 1 through the nozzle 9, and the liquid through the nozzle 10.

The proposed device allows the quenching of the kinetic energy of the flow entering the separation, which eliminates the vortex and wave formation and splashing, especially in the final stage of receipt of a liquid plug, for example, when a condenser plug transported by oil gas enters the device, and thereby improves efficiency separation of liquid from gas.
