Description

A kind of amberplex evaluating apparatus
Technical field
The present invention relates to a kind of amberplex evaluating apparatus, belong to the liquid separation technology field.
Background technology
Electrodialytic research starts from the Germany at the beginning of last century.First electrodialysis plant in the world made by nineteen fifty-two American I onics company, is used for brackish water desalination.Electrodialytic technique is under the effect of DC electric field, utilizing the yin, yang amberplex (is that anode membrane only allows cation to pass through to the selection permeability of yin, yang ion in the solution, cavity block only allows anion to pass through), and make solute in the solution and a kind of physical and chemical process of separated from solvent.Electrodialysis system alternately is arranged in and is formed many cells that separated by film between two electrodes by-serial yin, yang film.When pending stoste entered these cells, under the effect of DC electric field, the ion in the solution was made directional migration.Cation is to cathodic migration, and the anion anode is moved.But because amberplex has the selection permeability, the result reduces some cell ion concentrations and becomes freshwater room, the cell adjacent with light chamber then because of enrichment a large amount of ions become dense hydroecium.Obtain fresh water and dense water respectively from light chamber and dense chamber.Ion in the former water has obtained separating and concentrating, and liquid has just obtained purification.Utilize this characteristic of electrodialysis desalination, from products such as some chemical industry, medicine, food, remove inorganic electrolyte, reach separation, purification, purify and refining purpose, to improve the quality of product.
Amberplex is the core component of electric dialyzator, is a kind of membranaceous ion exchange resin.But, be applied to find a series of technical problem in organic separation, purification, purification and the subtractive process in the prior art electrodialysis, comprising: after the absorption of band polar organic matter tunicle, can change the polarity of film, and the selection permeability of film is reduced, film resistance increases; Metal ion (as iron, manganese) can make the ion-exchange membrane poisoning; Hardness ions (as calcium, magnesium) can cause the precipitation fouling that polarizes; In addition, along with the long-time running of electrodialysis plant, amberplex can produce permeability to partial organic substances, more than all technical problems all can reduce the operating efficiency of electrodialysis system, reduce the efficient of processes such as organic matter separation, purification.
The utility model content
The purpose of this utility model provides a kind of amberplex evaluating apparatus, be convenient to filter out in advance the lower amberplex of organic permeability, make the selection permeability and the operating efficiency that still can keep film after the electrodialysis plant long-time running that contains amberplex.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of amberplex evaluating apparatus, be characterized in comprising the fixture of U-shaped pipe, film to be evaluated and film to be evaluated, described film to be evaluated is fixed on described U-shaped pipe bottom by the fixture of described film to be evaluated, described film to be evaluated is separated into organic matter chamber and hydroecium with described U-shaped pipe, and described hydroecium is circumscribed with the COD checkout gear.
A kind of preferred as technical solutions of the utility model, the outdoor pump that is connected to of described organic matter.
A kind of preferred as technical solutions of the utility model, the fixture of described film to be evaluated is the loose joint pipeline.
A kind of preferred as technical solutions of the utility model, the fixture of described film to be evaluated is a flange.
A kind of preferred as technical solutions of the utility model, film to be evaluated is a cation-exchange membrane.
A kind of preferred as technical solutions of the utility model, film to be evaluated is an anion-exchange membrane.
In sum, the utlity model has following beneficial effect: use amberplex evaluating apparatus of the present utility model, in the organic matter chamber, add fluid organic material, in hydroecium, add pure water, observe the COD value of the COD checkout gear of this amberplex evaluating apparatus behind the certain hour, detection sensitivity height, accuracy are strong, be convenient to filter out in advance the lower amberplex of organic permeability, make the selection permeability and the operating efficiency that still can keep film after the electrodialysis plant long-time running that contains amberplex.
Description of drawings
Fig. 1 is the schematic diagram of amberplex evaluating apparatus of the present utility model;
Among the figure, 1-U shape pipe; 2-film to be evaluated; 3-organic matter chamber; The 4-hydroecium; The 5-pump; The 6-COD checkout gear.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, evaluating apparatus comprises the fixture of U-shaped pipe 1, film to be evaluated 2 and film to be evaluated, film 2 to be evaluated is fixed on U-shaped pipe bottom by the fixture of film to be evaluated, and film 2 to be evaluated is separated into organic matter chamber 3 and hydroecium 4 with U-shaped pipe 1, and hydroecium 4 is circumscribed with COD checkout gear 6.
Detect exchange capacity, transport number, face resistance, burst strength, the seepage of water of film 2 to be evaluated according to conventional method, selection has the film to be evaluated 2 of identical exchange capacity, transport number, face resistance, burst strength and seepage of water value, the organic permeability of film 2 to be evaluated is the unknown of starch sugar permeability especially, has to be evaluated.This evaluating apparatus especially is suitable for detecting the starch sugar permeability of film 2 to be evaluated.
In the organic matter chamber, add organic solution, in hydroecium, add pure water, film to be evaluated is fixed, reading on the COD checkout gear, the reading on the COD checkout gear is more little, illustrates that the organic permeability of film to be evaluated is more little, and the performance of film to be evaluated is good more.
Make the liquid level of organic matter chamber be higher than the liquid level of hydroecium, the pressure of organic matter chamber then is higher than hydroecium pressure, and evaluation time can shorten.This evaluating apparatus also can be in the organic matter chamber 3 external pumps 5, exert pressure for the organic matter chamber, make evaluation speed faster.
The fixture of film to be evaluated can be loose joint pipeline or flange.Film 2 to be evaluated can be cation-exchange membrane or anion-exchange membrane.
This specific embodiment only is to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification, but as long as all are subjected to the protection of Patent Law in claim scope of the present utility model.
