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 major defect of overflow type gas-liquid allotter is that pressure drop is little, and gas phase and liquid phase flow direction are vertical substantially, and structure is simple, and manufacture difficulty is lower, be comparatively applicable to high viscosity medium, is generally used for the occasion of 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.
Utility model content
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 overflow type gas-liquid allotter.
For achieving the above object, the utility model provides a kind of gas-liquid allotter, this gas-liquid allotter comprises cover plate and vertical central tube, cover plate is arranged on above central tube, described central tube includes oral area and falls liquid portion, liquid portion falls below inlet portion, pipe outlet centered by central tube lower end, the centrally tube axis direction that to fall in liquid portion of central tube arranges many rows of openings, it is characterized in that: described inlet portion comprises the rectangular slot or oval-shaped slot that centrally pipe top circumferencial direction opens, fluting quantity is 2 ~ 6, and its fluting direction relative centre pipe is tangential.
Adopt the utility model, there is following beneficial effect: during use, liquid phase enters in central tube by multiple through holes that the axis direction differing heights cross section of central tube distributes, gas phase tangentially enters in central tube at a high speed from central tube inlet portion, the air-flow of downward high-speed rotational is formed in central tube, above-mentioned gas phase produces the impact and the shearing that comprise the multiple directions of vertical direction to liquid phase, thus reaches better mixed effect.The utility model enhances broken stream atomizing effect, is conducive to being uniformly distributed of liquid phase.When the below of central tube outlet arranges stream breaker, the liquid phase raw material that central tube outlet at bottom flows out can be reallocated, eliminate 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 do not limit the scope that the utility model is claimed.
