The utility model relates to filtration plants for treating natural and waste waters, as well as other liquid solutions using ion-exchange processes, and can be used in energy, metallurgy, chemical and other industries that use demineralized or softened water in technological processes.

Currently, there are a large number of filtration units (filters) of various conductivity, differing from each other by the features of the used filtration material and the specificity of the separated mixtures. These include various nunch and druk filters, filter presses, and so on. (V.D. Lukin, Yu.A. Emelyanov, Filtration in the chemical industry, Ld, Chemistry, 1982, p. 36-61, pat. Of the Russian Federation No. 2058817.1995, class С02Р 1/42, A.N. Planovsky, PI Nikolaev, Processes and Apparatuses of Chemical and Petrochemical Technology, M., Chemistry, 1972, pp. 72-88) ..

Common to all liquid filters is the presence of a housing with devices for supplying the mixture to be cleaned and the filtrate outlet, as well as the filtration material placed in it

The prototin of the claimed technical solution is

MKJLC02P 1/42 FRSHTR

a device for the most effective method of water purification — filtering through a layer of ion-exchange resins (nat. RF No. 2058517,1995, class S02P 1/42). The installation is a corne with tubes and upper and lower distribution devices containing ion-exchange resin.

The disadvantage of the installation is the lack of cleaning efficiency associated with clogging of the filter material with impurities.

Ponggka tackled this task by introducing the APCOR technology (Dau Yuron catalog), which implies the introduction of inert material (inert) into the corne along with ion exchange resin with a clarity lower than the density of water in this type of filter was ineffective due to large resin losses and inert through the upper switchgear during regeneration by the flow from bottom to top when the housing is fully loaded or due to the low filter productivity when it is not properly loaded.

The problem solved by the authors was to modify the filter by equipping it with devices that allow it to hold the resin and inert in the corne.

This problem was solved by the installation in the upper and lower parts of the housing between pipelines and layers of resin or inert separation devices that freely pass water and do not pass particles of resin and inert. As such devices, in particular, partitions equipped with openings smaller than the size of the particles held in the housing can be used.

Optimal is the use of partitions equipped with filter caps. Moreover, when using the Apcor technology, the size of the slots of the caps located in the upper part of the body is on average 0.5 mm, and in the lower - 0.2 mm.

further notation:

1-filter housing;

2-layer ion exchange resin, for example, cation exchange resin;

3-layer inert;

4-upper pipeline;

5-lower pipeline;

6-upper partition;

7-lower partition;

8-filter caps;

9- viewing windows;

10-boot hatches.

The filter works as follows. In the working cycle, the liquid to be cleaned enters through the pipeline 4, passes through the partition 6 and caps 8, which fulfill the function of a switchgear, and then through inert 3 it enters the resin layer 2, where it is cleaned. After that, water passes through the caps 8, the partition 7 and goes to the consumer through the pipeline 5. The resin 2 is pressed against the partition 7, however, the size of the slots of the caps 8 prevents the entrainment of the resin. During the regeneration of the resin, the liquid flows from the bottom to the top through the pipeline 5, passes through the partition 7 and caps 8, thereby fulfilling the function of a distribution device, then through the resin 2 and inert 3, deactivating the washing of the resin, it passes through the caps 8, the partition 6 and leaves the filter through line 3. Inert 3 and resin 2 are pressed against the partition 6, however, the size of the slots of the caps 8 prevents the entrainment of inert and resin. Filtration control is carried out through viewing windows 9, loading and loading of filter material through loading hatches 10.

As shown by experiments, the performance of the modified filter compared to unmodified increases by 25-30%.
