Description
Technical field
The present invention relates to the apparatus for feeding of tower gas phase and gas-liquid two-phase, more particularly relate to the combined type feed distributor that a kind of two inlets feed distributor and biserial blade feed distributor combine.
Background technology
Tower is the industry-wide a kind of gas-liquid of petroleum and chemical industry, liquid liquid contact mass transfer equipment.Along with the maximization of packed tower and plate column develops, liquids and gases being uniformly distributed in tower is the key issue that tower amplifies, and the especially uniformity of gas-liquid two-phase feeding initial distribution, directly has influence on separative efficiency and the product quality of tower.
In recent years, apply more tower gas-liquid two-phase feeding distributor mostly in the industry to be and to realize being uniformly distributed of in tower logistics by the straight tube of perforate or other different feed stream guiding device.The speed flowed out due to the perforate that material is different from position is different, so this kind of distributor is difficult to reach the object being uniformly distributed material.Along with the maximization of tower develops, domestic and international many scholars are devoted to the research and development of feed gas distributor, and have developed the distributor of various ways, such as two inlets feed distributor and biserial blade feed distributor.These two kinds of feed distributors respectively have advantage, also have it not enough simultaneously.Two inlets feed distributor is comparatively even to gas velocity distribution, and liquid foam entrainment amount is few, and resistance is less, but due to material enter tower body after be all directed to below, disturbing influence certainly will be caused to operate to tower reactor liquid; The occupy-place of biserial blade feed distributor in tower is lower, and gas is horizontal distribution, avoid its disturbance to tower reactor liquid, but its design feature also determines it while uniform gas, makes gas create vortex phenomenon in tower, have impact on distributed effect.Although the application industrially of above-mentioned gas distributor improves the be evenly distributed degree of feed gas at tower to a certain extent, still there are some defects.
Summary of the invention
The object of this invention is to provide the combined gas feed distributor that a kind of two inlets feed distributor and biserial blade feed distributor combine, be characterized in two inlets feed distributor, add biserial blade feed distributor.The material of utilization to import of this combination is shunted, and weakens the vortex phenomenon that gas produces the disturbance of tower reactor liquid and gas in tower, reduces carrying secretly liquid, is uniformly distributed ascending air further simultaneously.
Object of the present invention is reached by following measures:
A kind of combined type feed distributor; It is characterized in that being combined by two inlets feed distributor and biserial blade feed distributor; Biserial blade feed distributor is added in two inlets feed distributor.
Described two inlets feed distributor, comprises inner sleeve, cover plate, cover plate reinforcement gusset, deflector, deflector reinforcement gusset, closure plate; Inner sleeve, cover plate and tower wall form the annular space of a top seal, bottom-open, deflector is arranged between tower wall and inner sleeve, both sides to be separately fixed on tower wall and inner sleeve and to be provided with deflector strengthens gusset, and deflector height gradually changes from charging aperture along circular passage, both sides; Closure plate is set at inner sleeve end, prevents tangential material from impacting biserial blade feed distributor.
Described biserial blade feed distributor, is made up of baffle plate, guide vane, guide vane stiffener; Guide vane is fixed by upper and lower two pieces of baffle plates; Guide vane stiffener is set between guide vane; Baffle plate is trapezoidal, and trapezoidal longer base is positioned at charging aperture side, and guide vane is fixed between upper and lower two pieces of baffle plates.
The trapezoidal longer base of biserial blade feed distributor used is positioned at two inlets feed distributor charging aperture side.
Material flows tangentially material and radial material in charging aperture punishment, enters into two inlets feed distributor respectively and biserial blade feed distributor distributes; Tangential material is evenly led at the bottom of tower by two inlets feed distributor; In space at the bottom of tower, gas-liquid is effectively separated, and liquid flows to tower reactor along tower wall, and gas is then transferred upwards; Radial material is horizontally separated by two tear blade feed distributor, and the inner sleeve running into two inlets feed distributor afterwards transfers to and upwards flowing.
Combined type feed gas distributor of the present invention is combined by two inlets feed distributor and biserial blade feed distributor.Two inlets feed distributor and biserial blade feed distributor are installed on bearing 1.
Gas-liquid mixed material or the gas-liquid mixed material being entrained with a large amount of drop and liquid foam enter combined type feed distributor by charging aperture, and material is split into tangential material and radial material.Wherein tangential material enters two inlets feed distributor, along the annular space flowing formed by tower wall and inner sleeve, cover plate, the deflector that some height and positions are different is provided with between tower wall and inner sleeve, the material entering distributor is led at the bottom of tower uniformly, in space at the bottom of tower, gas-liquid is separated, liquid flows to tower reactor along tower wall, and gas is then transferred upwards, and the drop in gas is effectively separated; Radial material enters biserial blade feed distributor, along the channel flow formed by baffle plate, guide vane, stiffener, radial material is separated in the horizontal direction, and the inner sleeve that separated material runs into two inlets feed distributor afterwards transfers to and upwards flowing.The basis of two inlets feed distributor is set up biserial blade feed distributor, by shunting, eddy current and the cyclone of uprising gas can be weakened, uprising gas is evenly distributed, also make the drop carried secretly be fully separated; Can also alleviate the disturbance to tower reactor liquid, when making operation, tower bottoms bit comparison is stablized.
The invention has the beneficial effects as follows, by reducing the vortex phenomenon that gas produces the disturbance of tower reactor liquid and gas in tower to the shunting of material, reduce carrying secretly liquid, be uniformly distributed ascending air further simultaneously.
