Description
Technical field
The present invention relates to a kind of catalytic reaction rectification filler tower internals in chemical field, and in particular to one kind is applied to catalysis
The Box-type Gas-liquid Distributor of reactive distillation.
Background technology
In the industrial productions such as oil refining, petrochemical industry, catalytic reaction rectification is important gas-liquid, liquid liquid-phase reaction system
Separation method, its principle are while catalytic reaction is carried out, with the process of the method separation product of rectifying, with traditional handicraft phase
Than there is the separation of side border ring, broken chemical balance, save the advantages of energy consumption etc. is notable, therefore the research one in this field
Directly it is taken seriously.In reactive distillation column, gas-liquid distributor is an important internals, and its main function is by into packed bed
The liquid of layer is evenly distributed on filling batch, under gravity by filling batch, is uniformly contacted with uprising gas.It is existing
Though be distributed device has had successful application example, certain defect, such as channel, the bad Distribution Phenomena of wall stream are still suffered from.
Type of feed of the catalyst on gas-liquid distributor then directly affects catalyst efficiency and gas-liquid mass-transfer efficiency in tower,
Because catalyst granules is smaller, and it is difficult to arbitrary shape and size is made；Moreover, existing Catalyst packing would ordinarily be encountered：Gas
The dynamic passage of liquid two-phase is smaller, catalyst contacts the problems such as poor with reactant；Existing Box-type Gas-liquid Distributor filling is urged
During agent, draining plate side aperture easily blocks, and catalyst can not contact well with liquid.
For problem above, the present invention develops a kind of Box-type Gas-liquid Distributor suitable for reactive distillation, solved emphatically
Loaded catalyst is small, the problems such as gas-liquid skewness, to improve two chances being in contact, plays the separation of reactive distillation column
Efficiency, ensure the stability of operation.
The content of the invention
Insufficient present in background technology in order to solve, the invention provides one kind to enable liquid phase and catalyst to contact very well
Box-type Gas-liquid Distributor, the advantages of slot type and disc type distributor, is combined as a whole, liquid collecting, cloth liquid is had concurrently, divides three kinds of gas
Effect, compact-sized, operating flexibility is high, and uniform gas-liquid distribution, resistance is smaller, is carried secretly especially suitable for easily generation, be susceptible to plugging
Occasion, using very extensive.
Box-type Gas-liquid Distributor of the present invention suitable for catalytic reaction rectification is real by the following technical programs
Existing：
A kind of Box-type Gas-liquid Distributor for catalytic reaction rectification, including bottom plate, liter air drain, baffle plate, cover plate, support
Plate, catheter and liquid collecting plate, bottom plate middle part is spaced and parallel to be formed with multiple liters of air drains, rises air drain top and is fixedly mounted with supporting plate, supports
Plate top is fixedly mounted with liquid collecting plate, realizes the backflow of liquid, it is characterised in that：Put down in the outside spacers of the relatively long side wall of liter air drain
Row sets baffle plate, and connection is mutually fixedly mounted with by a cover plate between baffle plate and liter air drain top, makes to be formed between baffle plate and liter air drain
With the cavity for logical liquid of ventilating, it is arranged at intervals between baffle plate lower end and bottom plate, and one section of steel wire is fixedly mounted between baffle bottom and bottom plate
Net, the clear width parallel vertical of the two relative longer side walls on the inside of liter air drain is fixedly mounted with multiple catheters, in corresponding catheter
Liter air drain lower sidewall be uniformly provided with distribution hole into catheter, the position of distribution hole is higher than the upper end of steel wire, ensures
Liquid is flowed into distribution hole after fully contacting catalyst；Passage is formed with the catheter sidewall upper public with rising air drain,
The section of baffle plate upper end is also formed with passage；Two drain holes are symmetrically formed with bottom plate.
Moreover, being fixedly mounted with silk screen in plate upper surface, the catheter is triangle, and shares a side wall with liter air drain.
It is described that catalyst is fully contacted with liquid be by a liter air drain wall, parallel point welding baffle, baffle plate upper end
It is concordant with liter air drain, and upper end has cover plate to shut, cover plate is provided with aperture in favor of lower end feed liquor.
When lower end is close to bottom plate, baffle plate becomes steel wire and is connected to bottom plate the baffle plate, so entirely rises air drain upper end
Outside the right and left has surrounded one layer of baffle plate, the row's steel wire of lower end two, liquid from liquid collecting plate flow down when, reached in the form of surface current
Bottom, overcomes when being not added with baffle plate that liquid-solid contact caused by line stream is uneven, reacts poor situation.The big of steel wire mesh is neglected
Depending on catalyst particle size.
Symmetrical drain hole is provided with described bottom plate, so that residual liquid flows out, to prevent catalyst from being missed from hole,
Weld one layer of silk screen in drain hole upper end.The liquid collecting plate is V-type plate, and thes brim of a hat of Bian Shangyou obliquely, the side of the brim of a hat is parallel with baffle plate,
To prevent liquid from directly entering from the perforate of baffle plate upper end between baffle plate and liter air drain.It is welding between described bottom plate and liter air drain
Structure；Described catheter is welded on a liter air drain interior sidewall surface, and catheter lower end is less than bottom plate；It is triangular in shape to rise air drain, rises
The passage that the distribution hole and top that air drain sidewall bottom is opened are opened is circular hole.
The advantages and positive effects of the present invention are as follows：
This distributor is simple in construction, is easily installed, and devises new catalyst type of feed, and turns to liquidus curve circulation
Surface current, contact area and the time of liquid phase and catalyst are added, reaction in tower is carried out more thorough, ensure that and reacted
Liquid inherently imitates contact in journey, improves the reliability of reaction.
The present invention is by Catalyst packing on Box-type Gas-liquid Distributor, and using baffle design, lower end is substituted small with silk screen
Hole, be not in catalyst blockage phenomenon, catalyst loading is big, and the liquid that liquid collecting plate flows down is changed into surface current from line circulation,
Catalyst contacts fully with liquid, so as to improve reaction rate, solve the structure of existing slotted disk gas-liquid distributor processing with
Deficiency during upper problem.
The present invention is applied to the packed tower of the gas liquid reaction system of all filling solid catalysts, particularly Catalyst packing
Measure larger catalytic reaction rectification system.
