Description

one

The invention relates to devices for the separation of gas-liquid mixtures, especially in the case of difficult degassing and increased aeration, and can be used in the petroleum, gas processing, chemical electrochemical, petrochemical and other industries.

A device for separating gas from a liquid is known, comprising a hydrocyclone embedded in a degassing tank and a settling tank connected to the tank of a drain pipe,}.

The disadvantage of the device is the complexity of the Design and intensive foaming. In the sump at the interface of liquid and gas.

The closest in technical essence to the present invention is a device comprising a horizontal body with a vertical pipe of introducing a gas-liquid mixture and nozzles of gas and liquid outlet, equipped with a collector with an elastic fibrous gasket newly attached to the pipe of the mixture inlet.}.

The disadvantages of the known device are the increased foaming on the surface, the liquid, and, consequently, the reduced efficiency of the degassing process.

The purpose of the invention is to increase the efficiency of the liquid degassing process and reduce foaming.

The goal is achieved by the fact that the device for separating gas from a liquid, including a horizontal body with a vertical gas inlet mixture inlet to which a collector with elastic fiber gasket and gas and liquid outlet pipes is attached, is provided with additional collectors with elastic fiber gasket and a diffuser, This collectors are made in the form of straight pipes and are attached to the input pipe around its perimeter at an acute angle; the mixture input pipe is provided with a fibrous gasket, a diffuser, and anovlen extension upwards and its narrowest part is attached to the pipe below the input Kolgo) projectors, the upper part of the diffuser is curved and placed over the output ends of the collectors, and the input pipe wall between the headers and the diffuser is provided with holes.

The drawing shows the proposed device, a longitudinal section. The device contains a horizontal body 1, partially filled

 5 liquid, in the upper suit of which. the pipe 2 of the gas-liquid mixture inlet and the pipe 3 of the gas outlet are located, in the lower part - the pipe k of the liquid outlet. Before nozzle 3

W gas output ustaiov drip catcher 5. To the pipe 2 angularly "1 less 90 adjacent additional collectors 6 m 7 with elastic fibrous packing 8 and the diffuser 9 with the collection of tori made in the form of straight pipe Nozzles attached at an angle less than the input nozzle on it the perimeter in the same plane, and the fibrous packing 8 is placed in diametrically opposite nozzles so that it overlaps the cross-section of the input nozzle. The diffuser 9 is directed upward with respect to the nozzle 2 input-ga-liquid mixture and

2 $ its narrow part is fixed below the collectors 6 and 7, and the wall of the nozzle 2 of the gas-liquid mixture inlet between the collectors 6 and 7 i with the diffuser 9 is perforated with through holes to.

The upper part 11 of the diffuser E is curved.

The device works as follows.

The liquid-liquid mixture flows through the nozzle 2 into the interior of the housing 1. In this case, the inertia of the liquid passes into the lower part of the nozzle. The film liquid is drained into the collectors 6 and 7 and is prevented by placing it at an angle to the inlet pipe smaller than 90. The droplet liquid coalesces in the collectors 6 and 7 in the fibrous packing 8 and flows down the lower collectors to the lower part of the pipe 2. Part of the liquid coalescing at the outlet of the collectors 6 and 7, flows down to the lower part of the nozzle 2 through the opening 10.

0 The coalescence of fluid at the exit of the collectors 6 and 7 is facilitated by the implementation of the upper part of the diffuser 9 somewhat tapering. The gas through the upper part 11 of the diffuser 9 enters the droplet eliminator 5, where it is further purified from the drip liquid, and through the outlet 3 of the gas outlet is vented to the atmosphere.

Having separated from the gas, the liquid in the direction of the ingress of the film liquid into the liquid is led through the manifold. The execution of the upper part

Improving the efficiency of the process of a curved diffuser leads to a further decontamination in the proposed device. The significant effect of coalescence is achieved for extra-fluid estimates at the collector outlet. Drain collectors placed under the additionally coalesced liquid to the nozzle. As a result, the bone is made using what reduces hydraulic pressure of 10. Placement of fibrous pressure on the exhaust gas of the gasket in the cross section of the inlet of the 3TM pin of the collector under JQ to the top coalescing a failure to pipe 2 leads exclusively to this pipe.
