Installation sorption treatment of grapes contains a pressure filter, filled with sorbent based on zirconium phosphate, pressure filter, water softening, water pump is the source of the grapes, the capacity for acid solution and the capacity for alkali solution, connected by pipelines with both filters, pipelines for supplying compressed gas to both the filter and the tank. 2 S. and 4 C. p. F.-ly, 1 Il. table 2.

The invention relates to methods and devices for sorption of wine, wines, cognac and grape juices from cations of metals (Fe2+Ca2+, Mg2+, K+and others) and radioactive nuclides (Cs134Cs137, Sr90and others) and can be used in wine-making and food industries.

Currently vindelici nami in static mode, the subsequent settling of the suspension, no mechanical filtration in filter presses.

For example, a known method of purification of wine material by mixing it with silica gel, followed by settling and separation of the phases (U.S. patent N 4.631.193, With 12 H 1/02, 1986).

Known similar methods for cleaning wine to use as sorbents powder

bentonite (U.S. patent N 3958023. 12 N 1/04, 1976).

magnesium silicate (U.S. patent N 3940498, With 12 H 1/04, 1976).

a mixture of silica gel with magnesium silicate (patent USA N 4797294, With 12 H 1/02, 1989).

modified diatomaceous earth (U.S. patent N 5009906, With 12 H 1/04, 1991).

The disadvantage of the above methods is the low capacity of the used sorbents for metals, as well as the impossibility of their use in the dynamic mode, which reduces the efficiency of the process.

The closest in technical essence and the achieved result is a method of purification of grapes, for example, vodka, including the pretreatment solution of activated carbon and clearing of metal ions using ion-exchange microporous sylvopastoral resin with subsequent regeneration and transfer to Na-form.

The same technical solution, psdi, filled with activated charcoal, connected by pipelines through the intermediate tank with a column purification filled with ion exchange resin and containing piping exhaust purified solution, and a regeneration effluent (U.S. patent N 3914442, With 12 H 1/04, 1975).

The disadvantage of this method is the use for treatment of polymeric ion exchange resins that are associated with the risk of leaching of bases toxic products of decomposition of the resins, and lack the recommended setup is its nonclosure, i.e. the inability to use it offline.

Another disadvantage is the low degree of purification from heavy metals and radionuclides.

The present invention is to develop a method and installation for sorption of wine, alcoholic drinks and grape juices from metals and radionuclides in the stream, which can operate with high performance offline.

The problem is solved is described by way of sorption of wine stock, including the transmission of wine stock through a filter filled with a granular sorbent on the basis of zirconium phosphate in the Na form, the regeneration of the sorbent by the in Na+-form processing solution of sodium hydroxide.

The problem is solved also described the setting for the sorption of wine material containing a pressure filter, filled with sorbent on the basis of zirconium phosphate with the supply line of the original wine stock and pipeline removal peeled grapes and regeneration effluent, pressure filter, water softening with granular ion exchange material, connected by pipelines with a pressure filter with a sorbent based on zirconium phosphate, tanks for acids and bases, connected by pipelines to the two pressure filters and additional pipelines supply gas to both pressure filters, and tanks for acid and lye.

The installation also includes a pump source grapes, shutoff and control valves. In addition, it contains a device for measuring and controlling the flow of wine materials and reagents and devices for measuring pressure drop across the filters.

Installation can additionally be provided with a filter source grapes from suspensions and colloids, installed before the pressure filter with a sorbent based on zirconium phosphate.

the burden of sorbent on the basis of zirconium phosphate 2 and pipeline peeled grapes 3; the pump 4 to the filing of the original grapes, connected by a pipe 5 with filter 1; tank 6 hydrochloric acid solution, connected by pipes 7 and 8 with the upper comb 9 filter 1; tank 10 sodium hydroxide solution, connected by pipes 11, 7, and 8 with the upper comb 9 filter 1; pressure filter 12 water softening with ion exchange load 13 and the pipeline of water supply 14 connected at its bottom by a line 15, 11, 7 and 16 with the lower comb 17 of the filter 1 and the top comb through 18 pipelines 19, 15 and 11 with the lower part of the alkali solution tank 10 and the lower part of the tank acid solution 6; pipes of compressed gas connected, on the one hand, with the upper die 9 and 18 filters 1 and 12 and the upper parts of the tanks 6 and 10, on the other hand, with the lower comb 17 of the filter 1 and the lower parts of the filter tanks 12 and 6 and 10; pipelines allotment regeneration solutions connected with the lower parts of the filters 1 and 2; pipelines stavki gas connected to the upper parts of the filter 1 and 12 and tanks 6 and 10.

The device operates as follows.

The original wine by means of a pump 4 through the pipe 5 is supplied under pressure in a pressure filter 1. Purified wine on line 3 is directed to a tank o which the pump is turned off. Remaining in the filter 1 wine displace the compressed gas in the tank peeled grapes.

Next, perform the regeneration of the sorbent. In the tank 6 is poured concentrated hydrochloric acid and bottom serves softened water from the filter 12 to obtain a desired concentration. The tank bottom 6 serves compressed gas for mixing the solution and removing the gas through suvcw 20. The prepared solution of hydrochloric acid compressed gas is directed to the filter 1 through the comb 9 and after passing the filter regeneration solution through the lower Gorbenko 17 dropping in buck Converter.

The filter 1 is washed with softened water from the filter 12 through the distributor 9 and the washing water is directed into the tank-neutralizer.

In the tank 10 is prepared NaOH solution. In the tank 10, at the top of the boot hatch, fall asleep granulated NaOH and served from below the necessary amount of softened water from the filter 12, stirred solution of compressed gas, which is fed from the bottom and away from the top through suvcw 21. The prepared solution of alkali serves compressed gas through the top comb 9 in the filter 1. At the same time through the lower comb 17 is supplied compressed gas for mixing the solution and the sorbent, which is withdrawn through suvcw 22.

P R I m e R s 1 and 2. The way sorption of wine was carried out at the facility, including a pressure filter with granular zirconium phosphate, centrifugal pump for feeding grapes, shutoff and control valves. Pressure filter was a cylindrical column with an inner diameter of 40 cm and a height of 80 cm, made of titanium. In the upper and lower parts of the columns are mounted drain caps slit width of 0.2 mm, the Volume loaded in the filter sorbent was equal to 48 liters of Granulated zirconium phosphate has the following main characteristics: the size of the granules of 0.4-2.0 mm, the atomic ratio P/Zr 2.0, the mechanical strength of the granules 15050 kg/cm2.

Through the filter of the sorbent on the basis of zirconium phosphate in the direction of "bottom-up" centrifugal pump filed the original wine with a bulk velocity of 20 column volumes per hour. After passing the filter materials were sent to the tank peeled grapes. In the original and cleaned the wine was determined by the concentration of iron, calcium, potassium and copper using standard techniques. In example No. 1 as cleaned grapes used dry white wine "Riesling Tamani. In the example N 2 obermaterial are given in table. 1.

The amount of the missed white wine "Riesling Tamani through the filter was 7.2 m3or 150 column volumes. After this was carried out by the regeneration of the sorbent. The filter with the sorbent was washed in softened water volume of 150 liters. Through a filter with a sorbent with a bulk velocity 4 column volume per hour missed 100 liters of 1 mol/l hydrochloric acid and regenerate sent in buck Converter. Further, the sorbent was transferred to the Na+-form processing 50 liters of 0.5 mol/l sodium hydroxide solution.

After completion of the regeneration process on the filter with the sorbent as in example 1, gave a dry red wine "Cabernet Tamani. Volume missed dry red wine amounted to 6,5 m3or 135 column volumes, then spent the regeneration of the sorbent as in example 1.
