Description

A kind of distributed gas-liquid pre-separate device

Technical field

This utility model is related to the technical field of gas-liquid gravity separator part, more particularly to a kind of distributed gas-liquid is pre- Segregation apparatuss.

Background technology

In gas-liquid separator design, we often separate the hydrocarbon under specified temp and pressure using Gravity separate method The gas-liquid component of fluid.Generally as separator is the initial management container of all devices, so separator is accurate Design is extremely important.If this processing unit design is inaccurate, " bottleneck " effect will be formed, causes complete equipment to process The decline of efficiency.And the separation efficiency of gravitational separator is heavily dependent on pre-separate device.Separator inlet fluid Usually typical high viscous turbulent flow gas-liquid mixture.As fluid is presented high viscosity and high coagulant state, thus its when entering separator with compared with High kinetic energy.Entrance pre-separate device by absorbing liquid kinetic energy and can change its flow direction, so that gas-liquid separation, the dress Put mainly solve the gas-liquid pre-separation of gas-liquid separator entrance fluid not exclusively and liquid splash, it is broken after a large amount of formation foams Technical problem.For gravitational separator, inlet device commonly use in current engineering and maturation is half-open tubular type and vane type Two kinds of pre-separate devices.Half-open tubular type pre-separate device is applied to absorption kinetic energy and is less than 2100Pa, and vane type pre-separate device is fitted For absorbing kinetic energy less than 6000Pa.During for entrance fluid dynamic energy more than 6000Pa, there is provided go out an efficient, compact, price Cheap and practicable pre-separation inlet device is eager needs.

Utility model content

In order to solve the deficiencies in the prior art, this utility model provides a kind of distributed gas-liquid pre-separate device, reduces dynamic Can, the breakup of drop is reduced, the efficiency of separator is further improved.

This utility model can be achieved through the following technical solutions：

A kind of distributed gas-liquid pre-separate device, including with bell-mouthed inlet tube, the horn mouth connects equipment entrance Pipe, one end connection of the other end and dried shrimps pipe of the inlet tube, the other end of the dried shrimps pipe pass through first flange and connection One end connection of pipe, the other end of the connecting tube pass through second flange and the connection of cover plate upper surface, multiple support angle steels Cheng Yuan All uniform grades are fixed between the cover plate lower surface and plate upper surface with gap, and multiple support beams are fixed on the base plate Lower surface and equipment barrel bottom is placed on, the two ends of each support beam are respectively and fixedly provided with steel plate, the radian of the steel plate It is identical with the radian of equipment barrel.

Further, the opening of the support angle steel is outwardly；The interior circular diameter of multiple support angle steel compositions is not less than company The diameter of adapter, outside diameter are not more than the diameter of tube sheet and base plate；The support beam is channel-section steel, perpendicular to equipment barrel axle The diameter of line direction and length more than base plate.

Further, the gap between multiple support angle steels is 30-50mm.

This utility model is beneficial to be had technical effect that：

The pre-separate device simple structure, low cost of manufacture, and the change of fluid parameter can be well adapted to, can be right Substantial amounts of air-liquid or solid carry out pre-separation, and insensitive to corrosive medium.Can be connected with any entry nozzle, can subtract Small inlet fluid dynamic potential energy, reduce to greatest extent drop crush and foam generation, be uniformly distributed medium, pressure drop ratio compared with It is little.Different rate of flow of fluids and liquid level can be passed through during concrete practical operation, the connecting tube and base plate of different length is selected The inlet device of size, it is to avoid the phenomenon of fluid splash occur.

Specific embodiment

Below in conjunction with the accompanying drawings and preferred embodiment describes specific embodiment of the present utility model in detail.

As Figure 1-3, equipment entrance pipe 1 is inserted in the horn mouth of inlet tube 2, the other end and the dried shrimps pipe 3 of inlet tube 2 Using being welded to connect；3 other end of dried shrimps pipe is connected with connecting tube 5 by first flange 4, and the first flange 4 includes two flanges, One is welded on dried shrimps pipe 4, and another is welded in connecting tube 5；The other end of connecting tube 5 is by second flange 6 and cover plate 7 Connected with securing member；Multiple support angle steels 8 are welded to connect with cover plate and base plate 9, and angle steel opening outwardly, is arranged in into even circumferential Between cover plate 7 and base plate 9, the gap between general support angle steel 8 is maintained between 30～50mm and is preferred.9 bottom welding of base plate Two support beams 10, support beam 10 are channel-section steel, and two pieces of arc plates 11 are welded at channel-section steel two ends, in 11 radian of arc plate and cylinder Wall radian is identical.

Whole inlet device is integrated, and is easy to integral demounting to install.The quantity of support angle steel is with gap according to practical situation Depending on.During work, after fluid-mixing enters pre-separate device, after support angle steel is shunted, as kinetic energy is reduced, medium delays Slowly by support angle steel gap, water droplet rises to that surface time is elongated, is thus provided that bigger chance and other droplet coalescences Bigger water droplet is formed, separation process is assisted.

Although the foregoing describing specific embodiment of the present utility model, it will be appreciated by those of skill in the art that These are merely illustrative of, and on the premise of without departing substantially from principle of the present utility model and essence, these embodiments can be done Go out various changes or modifications, therefore, protection domain of the present utility model is defined by the appended claims.
