Technical field

The present invention relates to the distributor fields of two kinds of liquid, and in particular to liquid distribution trough, and use the liquid distribution Device carries out precipitation reaction synthetic method.

Background technique

In precipitation reaction synthesis process, it is often necessary to the reaction that precipitating reagent and metal salt solution are added dropwise simultaneously.It is precipitating In the process, it first has to that precipitating reagent and metal salt solution is avoided to contact before instilling reactor, next needs to increase precipitating reagent and gold Belong in salting liquid and reaction kettle and react the contact area of bottom material, to increase precipitating reagent, metal salt solution and reaction still bed material Between mixability.Common practice is to improve the speed and structure of agitating paddle, to improve stirring efficiency.It is but raw in industry In production, in order to improve the production efficiency, precipitating synthesis reactor is often bigger, and revolving speed of agitating paddle etc. is often by certain journey Degree limitation, therefore it is necessary to add liquid distribution trough in the reaction vessel.

Existing liquid distribution trough is often used in rectifying column, in packed absorber, in order to reduce the bad distribution of liquid Caused enlarge-effect gives full play to the efficiency of filler, by liquid at the top of filler or a certain height carry out initial distribution Or redistribution improves alternate contact, and then improve column efficiency to improve the active surface of mass transfer, heat transfer.

CN106076076A discloses a kind of novel liquid distribution trough, which is used in packed absorber, A kind of liquid distributor, the water distributor are made of two layer system, and it is female that every layer system center water inlet sets up four main clothes separately Pipe, four main cloth main pipes are uniformly distributed, and set up cloth branch pipe in every main cloth main pipe separately, and each cloth branch pipe is divided into eight branches flower Flap-type arrangement, every cloth branch pipe are equipped with three splashing type external screw thread spray head, and the main cloth main pipe projection of four of two layer system is at 45 ° Alternate dislocation.The use of the liquid distribution trough improves the gas-liquid mass transfer situation in packed tower.

CN206198956U discloses a kind of throwing type liquid distribution trough, it is by inlet tube, taper liquid barrier and multilayer Liquid distribution plate composition；Several connection sheets, connection sheet edge are respectively set between taper liquid barrier and liquid distribution plate and between each layer liquid distribution plate Circumference uniform distribution will be connected and fixed between taper liquid barrier and each layer liquid distribution plate；Each layer liquid distribution plate is circular slab, each layer liquid distribution plate Center is drilled with round liquid-passing hole, and each layer liquid distribution plate equidistantly arranges from top to bottom, on each layer liquid distribution plate diameter and liquid distribution plate Liquid-passing hole diameter is gradually reduced from top to bottom；Liquid can be made horizontal spray by multilayer liquid distribution plate by this throwing type liquid distribution trough Formula distribution is penetrated, liquid distribution can be formed into multilayer paraboloid liquid film, cloth liquid is more uniform, and cloth liquid level product is big, is not easy to plug, has Conducive to gas-liquid contact mass-and heat-transfer.

But the above liquid distribution trough is usually that a kind of mixing liquid is evenly distributed namely a kind of liquid in some space Body is uniformly distributed.And precipitation reaction synthetic method usually requires to be uniformly distributed two kinds of liquid in a space.

CN204841597U discloses a kind of distributor of two kinds of liquid, and affiliated liquid distribution trough includes main body tube and connection Pipe, the both ends of the main body tube are respectively equipped with end socket, central interlayer are equipped in the main body tube, the bottom of the main body tube is equipped with Several first apertures, the center interlayer are equipped with several second orifices, and the diameter of first aperture is less than the straight of second orifice Diameter.So as to be suitable for the situation of charging of a large amount of material short time, and the aperture clogs of liquid distribution trough bottom can be prevented.But It is uniformly to be distributed two kinds of liquid between each other without effectively obtaining, only each liquid is divided in respective space Dissipate, i.e., it is higher with the concentration for reacting reactant A in the region that some is big when bottom material contacts, another region reactant B it is dense It spends higher.

To sum up, existing liquid distribution trough is chiefly used in a kind of being uniformly distributed for liquid, even if there is the distribution for two kinds of liquid Device, but be not able to satisfy for precipitation reaction synthetic method, namely on the one hand to ensure instilling reactor first two liquid It will not contact, on the other hand to guarantee that two kinds of liquid can be combined to efficient uniform with when reacting bottom material reaction.

Summary of the invention

Before overcoming two kinds of liquid of the existing technology to contact with reaction bottom material, two kinds of liquid It has contacted；After two kinds of liquid contacts with reaction bottom material, the low problem of three's mixing efficiency provides a kind of liquid distribution trough and sinks Shallow lake reaction synthesis process, the liquid distribution trough can guarantee that two kinds of liquid are not contacted with each other before haptoreaction bottom material, and due to The liquid distribution trough has staggered first distribution hole and the second distribution hole, so that after two kinds of liquid are contacted with reaction bottom material It can mix to efficient uniform.
