Abstract
A device for removing water from liquid mixtures which comprises a tubular cylinder closed at one end formed from a support matrix on which is crystallised a zeolite membrane over at least its lower part, in use the cylinder is placed in the liquid mixture with the zeolite membrane in contact with the liquid mixture so that the water passes through the membrane into the cylinder, optionally there can be a reduced pressure inside the cylinder.
Description
The present invention relates to a kind of liquid separating appts, more particularly, relate to a kind of dried up device that can be used for from other liquid, dividing.
It is known to divide dried up from other liquid with zeolite membrane, european patent application 0481660 discloses and has discussed existing zeolite type film, and US3244643,3730910,4578372, Applied Catalysts 49 (1989), 1-25, DE-A-3827049, CA1235684, JP-A-63287504, JP-A-63291809 and EP-A-135069 have been quoted especially as proof.
The routine of film in fluid separation applications used and comprised through-flow method, and wherein the liquid that will separate utilizes pressure reduction or gravity to make a kind of liquid by this film, and stays liquid mixture at the opposite side of film in a side of film.
Another kind method is to use cross-flow to separate, and wherein liquid mixture by the film surface, is removed a kind of liquid with continuous or semicontinuous logistics form from logistics under the effect of both sides differential pressure of membrane.
The device of setting up in these are used may comprise complicated pumping and control system, and liquid is injected in the device.
We have invented a kind of simpler and liquid separating appts more easily, and it is easy to on-the-spot the use.
According to the present invention, a kind of device of separating liquid is provided, it comprises the tube element that one the one end sealing other end opens wide, wherein the part of pipe comprises zeolite membrane.
Tube element can have any shape of cross section, and as circular, avette, oval, rectangle, square etc., circle or oval cross-section are preferred.The length of pipe is unimportant to the ratio of cross-sectional area, and this depends on application, and the shape of pipe can change in big scope, as from elongated tubular to short and thick pipe.
The tube element part that contains zeolite membrane is the zeolite membrane on supporting substrate preferably, and base material has woven wire or sieve, pottery or as the polymeric material of polysulfones or polyether sulfone etc., described in this list of references of mentioning in front.In the present invention, support membrane can be shaped to required shape to constitute the tube element part.
Preferably, the zeolite membrane of tube element part is near blind end, and in case of necessity, its end can be formed by zeolite membrane.
Another part of tube element can comprise the not supporting member of coverlay, or can be made by metal, pottery, plastic or other material.Material is unimportant, but requires to have enough intensity and suitable dimensional stability.It can be porous or atresia, this depends on how it uses.
Zeolite membrane should not have defective basically so that effective separation to be provided, and the zeolite membrane of describing among our the co-pending application PCT/GB95/02221 is preferred, and zeolite membrane is wherein handled with silicic acid.
The method of making silicic acid is described in the GB patent application 2269377, and preferable methods is the acidifying sodium silicate solution, is separated to isolate silicic acid with the organic solvent as oxolane then.Then, can dry organic facies and isolate silicic acid anhydride, for example obtain substantially anhydrous silicate solution by adding n-butanol.The degree of polymerization of silicic acid depends on employed physical condition, as sodium metasilicate before adding organic solvent and sour time of contact, temperature etc.
Be used for silicic acid of the present invention and preferably have 96-10,000 mean molecule quantity further preferably has the mean molecule quantity of 96-3220.
Except that handling with silicic acid, the zeolite type material can also be handled with alkyl ortho-silicate and alkoxyl ortho-silicate, the example of alkyl ortho-silicate has tetraethylorthosilicise (TEOS) and tetra isopropyl ortho-silicate (TIPOT), the example of alkoxyl ortho-silicate has the tetramethoxy ortho-silicate, when it is applied to the zeolite type material, formed poly-silicic acid.These alkyl ortho-silicates and alkoxyl ortho-silicate have formed the mesoporosity silicon oxide compounds, it mainly is made up of a series of poly-silicic acid unit that are linked together, each unit comprises the poly-silicic acid molecule of describing in the GB patent application 2269377, and comprise many three-dimensional materials (species) that are coupled to each other, each three-dimensional material or contain the silicon atom bridge, between each silicon atom oxygen atom is arranged, or on the silicon atom hydroxyl is arranged.
In one embodiment, tube element is to be formed by the base material that can be used as the zeolite membrane supporting member, and zeolite membrane is deposition, growth, crystallization or formation on the part of supporting member, and another part does not deal with.
Apparatus of the present invention can be used in two ways.In first kind of mode, apparatus of the present invention are placed in the container, and liquid mixture is placed in the tube element, and liquid mixture only contacts with the no bore portion of zeolite membrane or tube element like this.Can pass the liquid of zeolite membrane, for example, water passes film and enters container, thereby with fluid separation applications.For the ease of separating, preferably apply a pressure reduction in the both sides of film.
In another kind of mode of operation, liquid mixture is to be contained in the container, and this device is placed in the liquid, and that part that contains zeolite membrane of tube element contacts with liquid mixture.Can pass the liquid of zeolite membrane, for example, water is removed thereby enter tube element.For the ease of separating, preferably apply a pressure reduction in the both sides of film.
This device is particularly suitable for removing from liquid, aqueous mixture and anhydrates, for example, low-level water content is reduced to acceptable, for example, from solvent, diluent and other liquid, biology and the medicine that may be polluted by water and other heat-sensitive substance, remove and anhydrate.In an example, in the liquid, aqueous container that is contained in as beaker or winchester (Winchester) etc., apparatus of the present invention are placed in the liquid, and apply vacuum on tube element.Then, the water in the liquid mixture was suctioned through film.System can continued operation until in liquid mixture, having obtained desired degree of dehydration.Then device is shifted out, cleans and prepare against usefulness again,, then can discard if polluted by biology or drug substance.
Therefore, obtained a kind of easy carrying device that anhydrates that removes from liquid, aqueous mixture, this device adaptability is strong, is easy to use, and can be used for liquid mixture.
A feature of the present invention is can remove to anhydrate from liquid mixture, and does not need high pressure reduction in the film both sides, needs high pressure reduction in the application of disclosed zeolite membrane in the past.
The present invention is described among the following embodiment and accompanying drawing, and embodiment is used to illustrate the preparation of film, and accompanying drawing is used to illustrate the device of using film.The growth of embodiment 1 film
