Description
Technical field
The present invention relates to a kind of annular tube type uniform fluid distribution device, belong to uniform fluid distribution technical field.
Background technology
Along with the continuous reinforcement of offshore oil and gas resource exploration, exploitation dynamics, LNG-FPSO (platform is unloaded in the storage of offshore natural gas Floating Production) quickly grows.Wrap-round tubular heat exchanger, as the key core equipment of Large LNG-FPSO, has that heat transfer area is big, design pressure is high, allow the advantages such as big different transfer of heat.But, the heat exchange property of wrap-round tubular heat exchanger is had large effect by marine special operation condition, outstanding behaviours is rock the wrap-round tubular heat exchanger shell side flow distribution caused not to be respectively formed bias current, thus causing that heat exchanger overall heat exchange efficiency declines, and even substantial deviation design conditions.It is thus desirable to liquid phase fluid is carried out uniform by arranging uniform fluid distribution device, but although existing even distribution device preferably resolves the uniform problem of liquid phase fluid, but anti-shake to swing performance not good, it is impossible to be applied to sea and rock wrap-round tubular heat exchanger design and the exploitation of operating mode.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide a kind of annular tube type uniform fluid distribution device that can make uniform fluid distribution under the condition of rocking.
For achieving the above object, the present invention takes techniques below scheme: a kind of annular tube type uniform fluid distribution device, it is characterised in that: it includes a cylinder being vertically arranged, and is fastenedly connected the catch tray of a bottom opening in the upper end of described inner barrel；The liquid cylinder of a uncovered lower end closed in upper end it is arranged below at described catch tray；The bottom of described liquid cylinder is circumferentially arranged multiple horizontally disposed arm, and one end of each described arm connects with described liquid cylinder, and the other end of each described arm and described cylinder are fastenedly connected；The endless tube that at least one circle runs through and connects each described arm is set in the outside of described liquid cylinder；The bottom of described endless tube offers multiple equal discharge orifice.
The bottom opening of described catch tray is uncovered with the upper end of described liquid cylinder corresponding；Described collector tray bottom opening diameter is less than the uncovered diameter in the upper end of described liquid cylinder.
It is fastenedly connected a guide pipe connecting with described catch tray and downwardly extending at the bottom opening place of described catch tray.
A collecting tank in inverted cone shape it is fastenedly connected at the top of described liquid cylinder.
Described arm adopts pipe or rectangular tube.
Described equal discharge orifice adopts circular hole, square hole or slit-aperture type hole.
Due to the fact that and take above technical scheme, it has the advantage that 1, due to the fact that and be fastenedly connected a catch tray in the upper end of inner barrel, it is arranged below at catch tray that a upper end is uncovered, the liquid cylinder of lower end closed, therefore external fluid enters after in cylinder, gaseous fluid is by naturally all pressing and downward diffusional flow after catch tray, liquid phase fluid free-falling enters in liquid cylinder, and the uniform passage of fluid liquid phase is relatively independent, and the fluid that void fraction is big has better uniform effect.2, due to the fact that circumferentially arranged in the bottom of liquid cylinder has multiple horizontally disposed arm, at least one circle that arranges radially outside at liquid cylinder runs through arm and the endless tube connected with each arm, offer multiple equal discharge orifice in the bottom of endless tube, therefore liquid phase fluid arm, endless tube and equal discharge orifice realize being uniformly distributed of liquid phase fluid.3, in the liquid cylinder of the present invention, liquid phase fluid is played cofferdam effect by storage space, its internal flow minimum liquid level only need to be controlled during application, achieve that uniform fluid distribution function under the condition of rocking, efficiently solve sea and rock the flow distribution problem of non-uniform of wrap-round tubular heat exchanger shell side under working condition.4, the present invention adopts integrated design, equipment no-movable part, and simple and compact for structure, cost is low.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the present invention；
Fig. 2 is the structural representation of the endless tube of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
It is vertically arranged and the cylinder 1 of open at both ends as it is shown in figure 1, the present invention includes one, is fastenedly connected one in the upper end within cylinder 1 in inverted cone shape and the catch tray 2 of bottom opening.The liquid cylinder 3 of a uncovered lower end closed in upper end it is arranged below at catch tray 2.The bottom of liquid cylinder 3 is circumferentially arranged multiple horizontally disposed arm 4, and one end of each arm 4 all connects with liquid cylinder 3, and the other end of each arm 4 is all connected with cylinder 1 inner wall tightening.As in figure 2 it is shown, at least one circle that arranges radially outside at liquid cylinder 3 runs through arm 4 and the endless tube 5 connected with each arm 4.Offer multiple equal discharge orifice (not shown) in the bottom of endless tube 5, for enabling, the liquid phase fluid in endless tube 5 is uniform to flow out.
In above-described embodiment, the bottom opening of catch tray 2 is uncovered with the upper end of liquid cylinder 3 corresponding, and catch tray 2 bottom opening diameter is less than the uncovered diameter in the upper end of liquid cylinder 3, for making the liquid phase fluid collected by catch tray 2 can enter in liquid cylinder 3, it is prevented that leak outside.
In above-described embodiment, a guide pipe 6 connecting with catch tray 2 and downwardly extending it is fastenedly connected at the bottom opening place of catch tray 2, for controlling the flow of the liquid phase fluid collected by catch tray 2, enable liquid phase fluid following current in liquid cylinder 3, it is prevented that liquid phase fluid outwards splashes.
In above-described embodiment, it is fastenedly connected a collecting tank 7 in inverted cone shape at the top of liquid cylinder 3, for collecting the liquid phase fluid sputtered from catch tray 2 bottom opening edge.
In above-described embodiment, arm 4 can adopt pipe or rectangular tube.
In above-described embodiment, the current-sharing well format offered bottom endless tube 5 can adopt circular hole, square hole or slit-aperture type hole.
The present invention is operationally, extraneous liquid phase fluid after catch tray 2 is collected and is confluxed through guide pipe 6 vertical drop, in gaseous fluid freely uniform cylinder 1 to catch tray 2, liquid phase fluid is flowed in liquid cylinder 3 through collecting tank 7, realizes being uniformly distributed of liquid phase fluid by arm 4, endless tube 5 and equal discharge orifice.Meanwhile, when at sea rocking operating mode, in liquid cylinder 3, liquid phase fluid is played cofferdam effect by storage space, only needs fluid minimum liquid level in domination set fluid cylinder 3 during application, so that it may realize rocking uniform fluid distribution function under condition.
The various embodiments described above are merely to illustrate the present invention, and wherein the structure of each parts, connected mode etc. all can be varied from, every equivalents carried out on the basis of technical solution of the present invention and improvement, all should not get rid of outside protection scope of the present invention.
