Abstract

The utility model aims at providing a multilayer fin vapour and liquid separator, characterized by: at least comprises the following steps: the device comprises an outer cylinder body (1), a plurality of layers of fins (2), a gas-liquid mixed medium inlet (3), a liquid outlet (4), a liquid level meter port (5), a support piece (6), a gas outlet (7) and a manhole (8). The utility model discloses can be applied to ordinary gas-liquid separation, also can be applied to large-scale chemical industry and large-scale petrochemical industry field, can effectually compensate the not thorough not enough of gas-liquid separation after the upsizing of present vapour and liquid separator, block the effect principle of drainage through the multilayer fin, the effectual small liquid drop that smugglies secretly in with gas becomes big liquid drop, flows down until becoming the share.

Description

Multilayer fin vapour and liquid separator

Technical Field

The utility model belongs to large-scale chemical industry and large-scale petrochemical field, concretely relates to multilayer fin vapour and liquid separator.

Background

The traditional gas-liquid separator consists of an outer cylinder body for accommodating a gas-liquid mixed phase, a top gas-liquid separation wire mesh and a gas-liquid mixed phase inlet which is arranged on the side surface of the outer cylinder body and is separated by means of centrifugal force. Follow-up someone has developed the vapour and liquid separator of silk screen and swash plate combination, but the silk screen is more loaded down with trivial details with the welding of swash plate when the lectotype, the utility model discloses a multilayer fin's pattern utilizes multilayer fin to increase liquid phase and catches space and capture rate, makes vapour and liquid separator's separation efficiency effectively improve, and upper portion gas-liquid space smugglies the liquid volume greatly reduced secretly.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a multilayer fin vapour and liquid separator can be applied to large-scale chemical industry and large-scale petrochemical industry field, can effectually compensate that the gaseous phase smugglies secretly not enough of liquid after present vapour and liquid separator upsizing, and effectual separation gas-liquid is double-phase, overcomes the problem that present separator separation is not thorough, smugglies the liquid drop secretly. Meanwhile, the problem that the silk screen and the fins are not easy to weld and fix can be solved.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a multilayer fin vapour and liquid separator, characterized by: at least comprises the following steps: outer barrel, multilayer fin, gas-liquid mixture medium entry, liquid outlet, level gauge mouth, support piece, gas outlet, manhole.

The multilayer fin is more than two layers of fins.

The supporting piece is a steel structure truss girder, and is difficult to support by the outer ring due to the large diameter of the equipment.

The gas-liquid mixed medium inlet is an insertion pipe, a rectangular opening is formed in the lower part of the gas-liquid mixed medium inlet, and the insertion depth is larger than the radius of the cylinder body.

Effect of the utility model

The utility model has the advantages that: the gas-liquid mixed medium enters the gas-liquid separator from the gas-liquid mixed medium inlet of the multilayer fin gas-liquid separator 3, large liquid drops settle downwards under the action of gravity, and small liquid drops carried in a lower gas phase can be captured in the settling process. Ascending gas is smuggleing a small amount of liquid droplet and is passing through 2 multilayer fins, gaseous is earlier through fin below again through above fin, fin itself becomes 45 degrees contained angles, two-layer fin staggers and arranges, gaseous behind the fin wall below, the liquid droplet of smuggleing secretly in the gas can attach to on the fin, increase along with the liquid droplet of adhering to, the liquid droplet can form big liquid droplet or even become a share through surface tension effect and flow down, big liquid droplet and the liquid stream that flows down can effectually catch the liquid droplet in the gas phase that rises again at the decline in-process, gas through below fin is through above fin again, owing to two-layer fin staggers and arranges, just in time can block remaining small droplet of smuggleing secretly in the gas, on the fin big liquid droplet or become a share and flow.

Detailed Description

As shown in fig. 1, a multi-finned gas-liquid separator comprises at least: 1. an outer cylinder; 2. a plurality of layers of fins; 3. a gas-liquid mixed medium inlet; 4. a liquid outlet; 5. a level gauge port; 6. a support member; 7. a gas outlet; 8. a manhole. Manufacturing an outer cylinder body 1, finishing welding a gas-liquid mixed medium inlet 3, a liquid outlet 4, a liquid level meter port 5, a gas outlet 7 and a manhole 8 at the same time, and then welding a support piece 6 on the outer cylinder body; and 2 layers of fins are welded on the outside layer by layer and are arranged in the cylinder after being partitioned according to the design requirement. The perpendicular contained angle 45 degrees welding of fin of multilayer fin carries out the piecemeal design according to barrel diameter and manhole diameter, and inside the monolithic assurance can be sent into the separator through the manhole, convenient equipment adopted bolted connection inside.

Claims

1. A multilayer fin vapour and liquid separator, characterized by: at least comprises the following steps: the device comprises an outer cylinder, a plurality of layers of fins, a gas-liquid mixed medium inlet, a liquid outlet, a liquid level meter port, a support piece, a gas outlet and a manhole; the multilayer fins are composed of two or more layers of fins, the width of each fin is not more than 300mm, the number of the layers of the fins is calculated according to the liquid carrying amount in actual gas, the horizontal included angle of each fin is 30-60 degrees, the horizontal included angle of each fin is determined by gas flux calculation, the horizontal included angle of each layer of fins in the multilayer fins can be the same or different, the installation angle among the multilayer fins is rotationally installed at an included angle of 0-90 degrees, the specific angle is calculated according to the gas flux, and the liquid drops carried by the gas are prevented from directly permeating; the distance between the multiple layers of fins is 50-1000mm, each layer of fins is supported by a support piece welded on the cylinder, and a certain distance is reserved between the multiple layers of fins, so that liquid drops after the gas is guided by the fins can be freely combined and distributed in the gas again, and the next trapping and separation are facilitated; every layer of fin welding is on the roof beam, and the quantity of roof beam is more than 2, and the roof beam is arranged side by side, and the fin becomes vertical angle contact with the roof beam, but fin itself can inclination, and arranging of roof beam can play the effect of stabilizing and supporting the fin.
