The aim of the invention is to reduce losses, reduce consumption and one-time loading of ion exchangers.

The drawing shows an ion exchange apparatus.

The apparatus contains 2 zones: zone A - cationization and zone B - anionization, placed in housing 1, made in the form of a cone, pipe 2 for supplying treated water, pipe 3 for feeding cationite to the cationization area, pipe 4 for feeding anionite to the anion area A nozzle 5 for removal of cation exchanger pulp, a nozzle 6 for sampling anion exchangers, a perforated plate 7 with a hole diameter of 25 mm, a device 8 for discharging demineralized water, a filter charge 9, a device 10 for discharging an ion exchanger. The regeneration device contains cationite tanks 11 and additional anionite tanks 12, a drainage system 13, a cation exchanger and anion exchanger 14, a device 15 for discharging transporting cation exchanger or anion exchanger of water and post-regeneration solutions, a device 16 for supplying water for transporting cation exchanger and anion exchanger, a device 17 for receiving waste pulsz cation exchanger or anion exchange resin.

2/3 from the top of the cone. The nozzle 5 for collecting the spent cation exchanger pulp and the nozzle 6 for taking the spent anion exchanging pulp are installed 1/2 in and 4 respectively from the top of the cone and ensure synchronous feeding of the cation exchanger and anion exchangers to the regeneration device containing tanks 11 and 12 installed flush with body 1. 2 zp f-ly. 1 il. 2 tab.

a device 18 for supplying regeneration solutions.

The apparatus for continuous water free is as follows.

in a way.

The initial water from the averaging tank is pumped tangentially to the generator surface of the housing at the bottom third of the height of the apparatus. Fresh cation exchanger is dosed tangentially to the body of the apparatus at a height of 1/3 from the top of the cone, sampling of the spent cation exchanger is carried out at a height of 1/2 from the top of the cone, fresh anion exchange resin is metered tangentially to the body of the apparatus at a height of 2/3 from the top, the selection of the spent anion exchanger is carried out at a height of 3/4 from the top of the cone.

As a result of the tangential supply of water and ion exchanger, a flow turbulence and intensive ion exchange occur, which is completed in the upper zone of the separate soaking of ion exchange.

of the material, after which the cation exchanger and anion exchanger move to the place of constant release and then with part of the ionized water come into separate regeneration tanks of the cation exchanger and the anion exchanger prior to their filling. The ratio of cation-exchange material to the treated water is maintained within (O, 2-5.0): 100, with 0.2-10% of treated water being used to remove the spent cation exchanger from the body, which is separated from the latter in a tank 11, mixed with the original (or used as water of higher quality purification) and return

in the flow of the treated water, Miiu stage of loosening and washing the ion exchanger.

The ratio of anion exchange material to the treated water is maintained within (0.4-8.0): 100, and with water into the corresponding zones with ionization, 0.4-16.0% of water is used for the discharge of the spent anion exchange resin from the B-anionizing zone. while the water is also separated from the anion in the tanks

baths At this time, the filled containers of the cation exchanger and anion exchangers are brought to the regeneration stage, which is completed 3-5 minutes before the second tank is filled. Then the cycle is repeated.

anion exchangers 12 are mixed with the initial one (or used as water of higher quality purification) and return the stage of loosening and washing of the anion exchanger to the stream of treated water, mine.

The contact time of the cation exchanger with the treated water in the casing is 16-160 seconds with a ratio of the solid phase to the liquid in the pulp being removed for regeneration (1-2): 2. Contact time 20 ion exchanger in the regeneration device.

The anion exchanger with water to be treated in the housing is 32–200 s with the ratio of the solid phase to the liquid in the output itia. regeneration of the pulp (1-2): 2. The regeneration of the cation exchanger and the anion exchanger is carried out in a regeneration device in a dense layer of ion exchanger after separation of ionizable water from it.

3-5 minutes before filling the first tank 11 or 12, the regenerated ion exchanger from the second tank 11 or 12 is squeezed

water to the corresponding zones

baths At this time, the filled containers of the cation exchanger and anion exchangers are brought to the regeneration stage, which is completed 3-5 minutes before the second tank is filled. Then the cycle is repeated.

At the stage of transporting the regenerated ion exchanger into the apparatus with initial water under pressure, the stage of its washing with mass flow of water and sorption of cations with fresh cationite and anions, respectively, with anion exchanger, is completed.

The regeneration solution is fed to a partially dehydrated sealed.

and the separated post-regeneration solution through the drainage system 13, made in the form of a perforated pipe, is withdrawn from the system.

The technological parameters of the desalting process, depending on the quality of the source water and the proposed operating mode parameters, are presented in Table. 1 and 2 ..

As can be seen from the above data, the proposed intervals for contact time limits, the ratio T: W in the pulps to be regenerated are selected from the conditions for creating a spiral vortex flow regime that provides water desalination with a hardness of 4.3; 20.0; 40.0 mg eq / l to 0.2, 1.5; 3.0 mEq / l, with the elimination of the stage of loosening and washing the ion exchanger and reducing water consumption for the own needs of the process from 30 to 0.2%.

The proposed apparatus intensifies the process of water treatment with the exception of a simple ion-exchange apparatus during regeneration, and the creation of a filtering layer reduces the removal of ion-exchange material with treated water.h

The proposed apparatus also makes it possible to reduce the construction height of the apparatus by installing containers 11 and 12 on the same level as the apparatus.

In addition, the proposed apparatus makes it possible to eliminate water consumption for own needs due to circulation of transporting water flows. Formula of the invention
