Multiple gas-liquid allotter is located on tray deck according to certain rules, composition gas-liquid partition tray.Each gas-liquid allotter is allocation units, and gas-liquid two-phase by gas-liquid allotter, is distributed on beds jointly equably.
The mode that existing gas-liquid allotter enters gas-liquid allotter by liquid phase can be divided three classes: overflow type, suction type and the two mixed type.The main feature of overflow type gas-liquid allotter is that pressure drop is little, is comparatively applicable to the occasion that high viscosity medium is generally used for distributing high viscosity medium.Suction type gas-liquid allotter, this gas-liquid allotter is generally provided with the parts such as bubble cap, central tube, air-flow, by producing swabbing action in the annular space of slot between bubble cap and central tube, is broken into liquid punching drop and is carried by gas and enter central tube, realizes gas-liquid mixed and distribution.
Summary of the invention
The purpose of this utility model is to provide a kind of gas-liquid allotter, to obtain the more uniform mixed effect of gas-liquid mixed compared with existing suction type gas-liquid allotter.
For achieving the above object, the utility model provides a kind of gas-liquid allotter, comprise bubble cap and the central tube of coaxial setting, central tube is provided with top entry and outlet at bottom, the top of central tube is connected with the top cover of bubble cap with securing member by connector, it is characterized in that: the shape of central tube is rectangle or square, and bubble cap is circle bubble cap, form 4 the arc cylindrical spaces be communicated with between bubble cap with central tube, the bottom of bubble cap is provided with bubble cap bar seam.
The further technical characteristic of the utility model is: described bubble cap bar seam is rectangle, triangle, trapezoidal or oblique rectangular saw-tooth shape.
The further technical characteristic of the utility model is: described gas-liquid allotter also comprises stream breaker, and this stream breaker is horizontally placed on below gas-liquid allotter outlet at bottom, and stream breaker generally selects the flat board of perforate or not perforate, or opens Johnson's screen cloth of strip hole.
Adopt the utility model, there is following beneficial effect: the bubble cap bar sewer that the utility model adopts has broken stream atomizing, when arranging stream breaker, stream breaker also has broken stream atomizing, wherein central tube adopts square or rectangular structure, enhance broken stream atomizing effect, be conducive to being uniformly distributed of liquid phase.Stream breaker can be reallocated to the liquid phase raw material that central tube outlet at bottom flows out, and eliminates the phenomenon that below central tube, fluid flow is larger.Therefore, the utility model can make gas-liquid distribute more equably.In addition, the utility model also have that liquid phase spray area is large, pressure drop is little, operational stability is high, operating flexibility is large, the scope of application is wide, structure is simple, the advantage such as easily manufactured, firm stable.
The utility model is mainly used in the fixed bed hydrogenation reactor in petroleum refining and chemical industry.Liquid phase raw material can be assigned to equably on the beds in fixed bed hydrogenation reactor after being assembled into gas-liquid partition tray with tower tray, make it fully to contact with catalyst, to reduce the temperature difference in beds cross section, thus improve oil quality, reduce production cost.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.But the drawings and specific embodiments do not limit the claimed scope of the utility model.

Detailed description of the invention
See Fig. 1, a kind of gas-liquid allotter of the utility model, comprises bubble cap 1 and the central tube 3 of coaxial setting.Bubble cap 1 is circle bubble cap, and central tube 3 is square or rectangular, forms 4 the arc cylindrical spaces 9 be communicated with between bubble cap 1 with central tube 3, and the bottom of bubble cap 1 is provided with bubble cap bar seam 4.Bubble cap bar seam 4 can be the zigzag fashion (as shown in Figure 4) of rectangle, triangle, trapezoidal or oblique rectangle.Central tube 3 is provided with top entry and outlet at bottom, and the top of central tube 3 is connected with the top cover of securing member 7 with bubble cap 1 by connector 2.Central tube 3 and distribution plate 8 are welded to connect or adopt boss to lay to be connected, outlet at bottom has been horizontally disposed with stream breaker 6, and stream breaker 6 is not plate with opening (as shown in Figure 5) or be provided with the flat board (as shown in Figure 6, Figure 7) of broken discharge orifice or be provided with Johnson's screen cloth (figure slightly) seemingly opening strip hole.
See Fig. 1 and Fig. 2, preferred version of the present utility model is, the preferred rectangle of central tube 3 pattern, the arc cylindrical space 9 formed between the rectangular centre pipe of certain length-width ratio and circular bubble cap 1 can make the mixed effect of gas-liquid two-phase in space promote, thus promotes distributor performance; Stream breaker 6 preferentially selects the stream breaker structure with perforate, and as shown in Figure 6, Figure 7, when gas-liquid allotter works, the fluid above stream breaker 6 can part flow down from the perforate stream breaker, to ensure the gas-liquid flow in gas-liquid allotter lower central region; Central tube 3 connects with the connection preferred weld of distribution plate 8, and welding connection structure prevents liquid phase fluid to leak from junction, and syndeton is firm, avoids the vibrations caused by the broken stream of gas-liquid impactor.Bubble cap bar seam set by bubble cap 1 bottom is preferably rectangle, and quantity is generally 4 ~ 12.The securing member 7 for fixing bubble cap 1 of above-mentioned connection bubble cap 1 and connector 2 can be bolt and nut, also can adopt and be welded to connect.When adopting bolt and nut to connect, as shown in Figure 1, bolt passes the circular hole of bubble cap 1 top center circular hole and connector 2 (as shown in Figure 3), and with fastening nuts, centre generally arranges pad and ensures to tighten.The structure of connector 2 is general structure, and do not affect gas-liquid mixed effect, the utility model should comprise the simple variant of these parts.
For the gas-liquid allotter shown in Fig. 1, simple workflow of the present utility model is described below.The bar seam 4 of gas phase on bubble cap 1 enters arc cylindrical space 9, enter in central tube through central tube 3 entrance again, liquid phase is carried by gas phase, also enter central tube 3, at bubble cap bar seam 4, arc cylindrical space 9 place, gas-liquid interacts tempestuously, liquid phase is atomized by broken stream, at the outlet at bottom place of central tube 3, the atomization of broken stream is entered-walked to liquid phase through stream breaker 6, at the flows by action of gas phase kinetic energy.Finally, liquid phase raw material is evenly distributed on the beds in reactor.
