Description

one

And venting refers to a device for densifying liquids; in particular, it can be used to purify waste water, desalinate fresh salt water and deep desalination of fresh water.

A multi-chamber electrodiode is known, which contains electrodes, cation-exchange and aiii OHOo6.M6HHbie membranes and clamps of the distance between the membranes, wound from the insulation material. The retainer is a piece of fabric from the imitation of the plagtika - half of a brush, polyethylene. iolivi 1 chloride and so on

But the rest: .mp and the most efficient electrodialyzer are the increased power consumption due to the electric distance between the canal 1 and the high hydrodynamic connection in the eleven aipat ata.

In the proposed multi-meter: but; electric diffuser, the fixers between the furniture 1a and mi are wired in the form of thin ciipyH, located one next to each other in each chamber and perpendicular to any of the two adjacent chambers. This makes it possible to reduce power consumption and reduce the pidrodinamic resistance of the apparatus.

FIG. 1 shows the described electronic dialyzer with a section along LL; in fig. 2 - spatial image; -1e of a partitioned 5 l ect and a l i 13 ato; p a.

Electrod | The analyzer consists of two electrode cathode chambers 1 and anodic chambers 2, between which a package of alternating cation-exchange and anion-exchange membranes is clamped, 4. The membranes are separated by clamps 5 in the form of non-conducting thin strings parallel to each other

in each chamber and mutually perpendicular n any of the two adjacent chambers. Thus, some strings are enclosed in the chambers of the depleted1, and the others (lerandyklernye ilg) - in the chambers of the kong;

The flow of fluid through the concentration of the axle1, is carried out with a mono and niero supply and discharge manifolds 6 and 7. The solution will discharge the desalted water into the chamber through the manifold and out through the upper

collector .9. Shg-centers 10 and 11 serve to power the anode chamber; fittings 12 and 13 for feeding the cathode chamber; Shtutsera 14-17 - for powering collectors. On the side of the iodine / 5 with the down-conductor 19, the annonite membrane is attached, and on the side of the cathode 20 with the down-conductor 21 - the KaTHOiHHTOBan membrane. Mesh 22 made of organic glass and preventing membrane deflection are introduced into the electrode chambers.

The starting solution enters the electrodialyzer through the nozzle 14 and is discharged through the nozzle 15. During the circulation of the operation; the solution; and through the chambers of the two salt solutions, the salts contained in the solution migrate through the cationic and apioioexchange mums Stages 5 and 4 into the concentration chambers. When the desired degree of obvolization is achieved, the solutions from the chambers are mixed with water and concentrated and drained, the system is filled with OUTLINE with water and the cycle is repeated, obvssol (and 1).

An electric dial collector is assembled from ten M.C.-40 catioite membranes and ten a.onitic MVM1BRA MA-40 membranes with an area of 1 dm each. In CTpyiH, a fishing line with a diameter of 0.3 mm is used, located in camara with a 2-mm shch-ag.

Zredl auger electr / rodialyzer during desalination of a solution of Na2SO4 with a concentration of from 3.5 to 0.5 at a current density of 0.2 a1 dm

It has a power consumption of 0.3 kWh / kg of salt removed. Concentration of pacTBOipa circulating in concentric electrode chambers, i); ni, sasta (is about 60 g / l. In modern frame electrodialyzers with the same current density, the flow rate of elaptoanaline is to remove 1 kg of salt 0.6 kWh

PRIOR 1MET and W obre e IH and

Multi-dimensional electrodialysis product containing electrodes, cation-exchange and anion-exchange membranes and spacers between the membranes, made of insulating isoiHHoro material, characterized in that, in order to reduce the cost of electrical energy and reduce the energy output of the body, it will be applied to the device. as strings arranged in parallel in each chamber and mutually perpendicular in any of the two adjacent chambers
