Description
Technical field
The present invention relates to the technical fields of cryogenic heat exchange equipment end enclosure structure design, and in particular to one kind is suitable for rocking work
The plate-fin heat exchanger end socket of condition.
Background technology
Plate-fin heat exchanger is widely applied cryogenic heat exchanger in natural gas.The heat exchanger by usually by partition board, fin,
Strip of paper used for sealing, flow deflector composition.Fin, flow deflector and strip of paper used for sealing are placed in adjacent two partition room and forms an interlayer, referred to as channel, by this
The interlayer of sample is stacked according to the different modes of fluid, is brazed into a single piece just composition plate beam, plate beam is plate-fin heat exchanger
Core.Cold fluid and hot fluid carries out heat exchange by plate and fin.
When plate-fin heat exchanger is applied to floating platform on sea, due to being influenced by stormy waves, heat exchanger can be with platform
It moves together, these movements lead to degradation of heat exchange performance of heat exchanger.The main movement form of platform is to shake.In the process of shake
In, long-time is in heeling condition by floating platform on sea, causes heat exchanger integral inclined, at this time as shown in figure 3, inside end socket
Fluid can be collected in because gravity influences the flowing that shifts and tilt side, to which portion of runner entrance enters refrigerant fluid
Very few, liquid phase refrigerant can not come into full contact with heat exchange plate fin, decline so as to cause the performance of entire heat exchanger.
Through the literature search of existing technologies, have Patent No. CN104990433A, entitled " plate fin heat-exchanging
The patent of device ", by heat exchanger side be arranged end socket to realize by gravity come realize the gas-liquid separation of entrance cryogen come
It solves the problems, such as because heat exchanger efficiency caused by gas-liquid mixes declines.But current technology there is no method to solve because inclination leads to two
Refrigerant into air stream enter runner time-division cloth it is uneven caused by degradation of heat exchange performance of heat exchanger the problem of.
Have Patent No. CN102914204A, entitled " a kind of distributor and the plate-fin with the distributor simultaneously
The patent of heat exchanger ", by the way that distributor is arranged between each layer channel in the inlet and heat exchanger of gas-liquid two-phase fluid, and
Distributor body space is separated into several liquid phase channels with partition board, to solve in shaking cryogen in each channel
The middle non-uniform problem of distribution.But the technology is complex, and the plate-fin heat exchanger that can not be directed to different model formulates unified mark
It is accurate.
Invention content
An embodiment of the present invention provides a kind of plate-fin heat exchanger end sockets being suitable for rocking operating mode, in order to solve existing skill
Plate-fin heat exchanger is unevenly distributed for leading to the problem of gas-liquid when marine large-scale liquefied natural gas plant in art.
In order to solve the above-mentioned technical problem, the embodiment of the present invention adopts the following technical scheme that：
It is a kind of to be suitable for rocking the plate-fin heat exchanger end socket of operating mode, end socket internal liquid distribution structure by inlet baffle,
Water conservancy diversion pipe and runner demarcation strip composition；The inlet baffle is placed in end socket refrigerant inlet bottom, in the inlet baffle
Between open multiple holes；The water conservancy diversion pipe includes multiple, and an end of the water conservancy diversion pipe is connected on the circular hole of inlet baffle, the other end
Lead to a certain runner, and the end of the water conservancy diversion pipe is equipped with nozzle；Runner is divided into several streams by the runner demarcation strip
Road region.
Wherein, the inlet baffle, water conservancy diversion pipe, runner demarcation strip and nozzle are process by aluminium sheet or stainless steel plate,
It is consistent with heat exchanger shell material.
Preferably, the size of the inlet baffle is equal in magnitude with end socket entrance cross-section, aperture and water conservancy diversion pipe caliber
Equal, the intermediate number of aperture of the inlet baffle is determined by plate-fin heat exchanger end socket inlet diameter.
Preferably, the thickness of the water conservancy diversion pipe determines that caliber is big by exchanger head according to specifically used pressure environment
Small and refrigerant flow determines.
Wherein, the end diameter of the nozzle is identical as water conservancy diversion pipe.
Preferably, the thickness of the runner demarcation strip determines that width is equal with width of flow path by specifically used pressure environment,
Height is determined by end socket size.
Beneficial effects of the present invention are：An embodiment of the present invention provides a kind of plate-fin heat exchangers being suitable for rocking operating mode
End socket, end socket internal liquid distribution structure are made of inlet baffle, water conservancy diversion pipe and runner demarcation strip.In application, fluid is from envelope
Head entrance enters, and by inlet baffle, is divided equally to each water conservancy diversion pipe and imports by the correspondence flow passage area of barrier partitions, thus
Realize that refrigerant enters the substantially uniform distribution of flow channel entry point, refrigerant enters plate-fin heat exchanger later, through plate and fin
It is flowed out after exchanging heat with another layer fluid.The present invention is restrained and by multiple row of arranging inside end socket by being arranged in flow passage area
It is divided into several regions by baffle, ensures that the distribution of refrigerant for being assigned to each flow passage area is more uniform, while reducing and inclining
The flow difference of each feeder connection, efficiently solves into heat exchanger caused by air stream enter runner distribution of refrigerant unevenness caused by when tiltedly
The problem of capable of declining.
