Description

This invention relates to multi-stage methods of non-reagent micro-purification of fresh water from water supply networks, deep and surface sources without changing the salt composition to the requirements of SanPiN 2.1.4.1074-01 "Drinking water. Hygienic requirements for water quality of centralized drinking water supply systems. Quality control" and other liquids .

A known filter for cleaning liquids, comprising a housing in which an external filter is arranged concentrically to the housing and several internal filters with pore sizes smaller than those of the external filter. Filters are made of homogeneous polymer fibers forming a deep filtering structure (1).

A known installation for micro-purification of liquids containing a detachable housing with nozzles for supplying and exiting fluid, filter elements are placed in the housing. The filtering elements are made of homogeneous polymer fibers (2).

Known portable two-stage sorption filter. The disadvantage is low productivity, a limited list of filtered contaminants, and the absence of methods to control the saturation with pollution of sorption material (3).

Known three-stage cartridge filter for liquid with a homogeneous filtering mass of different densities (4).

Known multi-stage, multi-module installation for deep water purification, including a pre-filter module, a sorption purification module with carbon fiber material with the introduction of reagents containing silver ions, and gaseous ammonia or ammonia water, as well as a UV treatment module, which allows to obtain high-purity water for long-term storage and in areas with adverse environmental conditions (5).

By the combination of essential features and the achieved result, it is the closest analogue of the claimed invention.

Its disadvantages include the bulkiness of the design and the complexity of the implementation, energy dependence, relatively limited performance, multi-module design (each cleaning step is made in a separate housing), the presence of connecting elements between the cleaning steps, the inability to clean liquids with elevated temperatures, alcohol- and acid-containing liquids. The use of a multilayer mesh complicates the washing and regeneration process, since a layer of sludge sticks between the layers, which reduces the filtering ability.

The technical problem to which the present invention is directed is to expand the arsenal of effective single-module multi-stage, deep micro-treatment of deep and surface fresh water without changing the salt composition of household and industrial purposes for domestic and industrial use with a service life of at least 10 years and creating a simple and reliable operation of an environmentally friendly non-reagent device for micro-purification of water and other liquids.

The task is achieved in that a single-module installation of multi-stage deep cleaning of liquids includes a detachable housing with inlet and outlet nozzles and a filter element made of concentrically mounted relative to each other and the cylinder body of dissimilar materials:

- the outer cylinder is made of a single-layer woven stainless steel mesh with a predominant mesh size of 20-25 μm, stretched over a frame made of perforated stainless steel sheet,

- the middle cylinder is made of porous polypropylene with a wall thickness of 18 mm with a filter fineness of 20 microns on the outer surface to 5 microns on the inner surface,

- an inner cylinder made of sintered titanium powder, with a predominant pore size of 5-7 microns.

The installation can be equipped with additional, similarly made filter elements installed not concentrically to the housing.

The installation can filter liquids with temperatures from + 5 ° C to + 70 ° C. When treating water from deep sources with a high content of dissolved iron, manganese, odors and taste, forced or natural aeration of the water is used.

The design of the micro-purification liquids is illustrated in the drawing.

Installation for micro-purification of liquids contains a detachable housing 1, 5 with an inlet pipe 2 for supplying the source liquid and an outlet pipe 3 for the output of the purified liquid. A plug 4 is installed on the inlet pipe 2 for venting air from the installation when it is put into operation. The housing 1 is connected to the housing cover 5 through a seal with a quick-release clamp 6. In the housing 1, an outer cylinder 7 of a single-layer woven stainless steel mesh with a predominant mesh size of 20-25 μm stretched over a frame made of a perforated stainless steel sheet is placed concentrically to each other and the housing in the form of a glass with a tight rigid bottom in the lower part and an annular rim 10 mm wide in the upper part from the inside, the middle cylinder 8 is made of porous polypropylene with a wall thickness of 18 mm with a filter fineness of 20 microns on the outer surface, up to 5 μm, on the inner surface, on the lower end of which a sealed elastic plastisol patch is welded along the cylinder diameter, and a plastisol ring with an outer diameter of 1 mm larger than the inner diameter of the ring rim of the outer cylinder and with an inner diameter of 1 mm is welded to the upper end smaller than the diameter of the inner cylinder (the dimensions of the sealing plastisol tips are chosen so as to ensure a sequential passage of the filtered fluid first through the external qi linder, then through the middle and then through the inner), inner cylinder 9, made of sintered titanium powder with a predominant pore size of 5-7 microns.

The filtering elements 7, 8, 9 through rubber seals 10, 11 are attached to the cover 5. At the bottom of the housing 1 there is a plug 12 for draining the liquid from the installation before disassembling.

Installation for micro-purification of liquids works as follows.

The source fluid enters the inlet pipe 2 and moves inside the housing 1 between it and the external filter element 7, seeps out gradually through the filter elements 7, 8, 9. The purified liquid enters the consumer through the outlet pipe 3. When the unit is put into operation, air from it can be released with a plug 4. Before disassembling the installation, the fluid is drained with a plug 12.

Additional differences are that the installation allows you to filter wine-vodka and other alcohol-containing products, soft drinks, mineral waters, vegetable oils; acidic liquids; filter liquids with temperature from + 5 ° С to + 70 ° С; the increase in productivity is achieved by the manufacture of installations with additional, similarly made filter elements installed not concentrically to the housing, as well as the parallel inclusion of several installations; when treating water from deep sources with a high content of dissolved iron, manganese, odors and taste, forced or natural aeration of water is used; installation does not require electricity.

The maximum cleaning effect is achieved by manufacturing filter elements with the indicated pore sizes, observing the geometric dimensions of the cylinders and the size of the gap between the filtering surfaces, the quality of the material and the size of the sealing elements, and the passage speed of the filtered fluid.
