Description

The inventive utility model relates to a device for purifying a liquid by filtration using a sorption process, in particular, to produce drinking water and can be used in process water treatment systems for various industries, for domestic use, as well as in the field.

One of the main components of various liquid purification systems is replaceable filter elements, called either cartridges or cartridge filters. According to the description of the proposed device options relate to sorption cartridge filters, and more specifically to replaceable filter elements-cartridges of these filters used in flow systems for cleaning liquids by the dead-end filtration method.

Known portable filter for drinking water purification, containing a housing in the form of a funnel, a drainage grate with a packet of filter elements made of activated carbon fiber material placed on it and a means for reducing the porosity of the peripheral part of the filter elements, while a part of the housing or drainage grate located below the tool is waterproof [Pat. RU 2066301, IPC C02F 1/18, B01D 24/22, 09/10/1996].

A disadvantage of the known portable filter is the material from which the filter elements are made, which does not provide microbiological purification of water, as well as insufficient purification from heavy metals, since carbon sorbents are more suitable for sorption of organic pollutants.

Known country filter "Dolphin-D-3,5." The cottage filter is intended for purification from metals, nitrates, nitrites, pesticides, organochlorine compounds, chlorine and other water from wells, wells used for drinking. The cottage filter provides for the possibility of systematic washing of a removable cartridge located in the inlet of the filter, as well as a removable block of filter elements located in this cartridge, designed to purify water from mechanical impurities and consisting of a set of layers of porous filter cloths located between two perforated synthetic gaskets material. A drainage tube made of synthetic material passing through the center of a set of filter layers and perforated gaskets is also a handle for removing a removable block of filter elements from the filter when washing it [Pat. RU 2146962, IPC B01D 24/12, C02F 9/00, 03/27/2000].

The known device is not intended for microbiological purification of liquids.

Known cartridge filter element [US Pat. RU 60874, IPC B01D 27/06, 02/10/2007]. Two variants of the cartridge filter element are proposed, the first version of the cartridge filter element contains a perforated tube and a layered filter material formed around it, connected by end parts, the filter material formed around the perforated tube in the form of a cylindrical roll, made in the form of a “sandwich”, the lower and upper layers which are synthetic non-woven material that freely passes water, between which there is an inner layer of sorption material n based fibrous sheet material of organic or inorganic origin, intended for fine-water purification and water purification from microorganisms, wherein the inner layer is formed as a smooth belt formed of a plurality of layers of the sorption material. The second version of the cartridge filter element contains a perforated tube and a layered filter material formed around it, connected by end parts, the filter material formed around a perforated tube in the form of a cylindrical roll, made in the form of a “sandwich”, the lower and upper layers of which are synthetic non-woven material, freely water-permeable, between which there is an inner layer of sorption material based on a fibrous sheet material of organic or ganic origin, modified nanoscale particles of alumina hydrate, intended for fine-water purification and water purification from microorganisms, wherein the inner layer is a corrugated tape formed of a plurality of layers of the sorption material.

This cartridge element is effective for cleaning microorganisms, but does not allow sufficient purification of liquids from heavy metals.

The closest in technical essence and result to the proposed device is a cartridge for cleaning liquid, containing a perforated frame, formed around it in several layers of sorption-filtering material, including at least two layers of protective material and placed between them a multilayer sorption material that supports an element worn over a sorption-filtering material and a glass with loading from a sorbent of heavy metals, mounted inside and on the same axis with a perforated frame m are connected end parts [Pat. RU 87365, IPC B01D 27/04, B01D 27/08, B82B 1/00, 10/10/2009].

The disadvantage of this device is the susceptibility to clogging of the pores of the sorption material with mechanical impurities, which leads to a rapid decrease in the efficiency of the cartridge.

The objective of the proposed technical solution is to develop a replaceable cartridge with a high degree of purification of the liquid from harmful impurities.

Effect: increase the productivity of the filtering process and increase the degree of purification of the liquid.

The technical result is achieved by the fact that the cartridge for cleaning liquid contains a coaxially mounted glass with loading from a sorbent of heavy metals, a perforated frame, a sorption-filtering material, comprising at least two layers of protective material and a multilayer sorption material placed between them, and supporting an element connected by end parts, while the layers of protective material are made in the form of elastic tubular knitwear by weaving a tubular surface from simultaneously knitted with carbon and elastomeric threads.

The implementation of the layers of protective material in the form of an elastic tubular knit by weaving a tubular surface from simultaneously knitted carbon and elastomeric threads provides additional cleaning of the liquid due to the extremely dense looped structure of the knit provided by the skeleton of the elastomeric thread and carbon thread, providing sorption cleaning of the liquid. Due to this, there is an increase in the productivity of the filtering process and an increase in the degree of purification of the liquid.

In this case, the layers of the protective material do not impede the passage of the liquid being cleaned, act as a carbon filter and filter from mechanical impurities, and protect the multilayer sorption material from damage.

In FIG. 1 shows a diagram of a cartridge for purifying a liquid; FIG. 2 is a graphical representation of an elastic tubular knit.

The liquid cleaning cartridge contains a perforated frame 1 made of polyethylene, polyamide, polypropylene or other food grade thermoplastics, on which a multilayer filter material is formed in the form of a cylindrical roll of at least two layers of sorption-filter material 2 prefabricated in the form of " sandwich ", with an internal sorption layer 3, placed between two layers of protective material 4, made in the form of an elastic tubular knitwear from simultaneously knitted with carbon and elastomeric threads.

Inside the perforated frame 1, a cup 5 is placed on the same axis with it, loaded with a heavy metal sorbent 6. On top of the load 6, a retaining perforated element of polymer material 7 is installed.

On the sorption-filtering material 2 with the inner sorption layer 3 and the layers of the protective material 4 is worn supporting element 8.

End parts 9 located at the ends of the cartridge, mechanically connected with the perforated frame 1, do not allow sorption-filtering material 2 to move along the perforated frame 1 and serve to attach the cartridge to the filter holder.

The elastic tubular knitwear by weaving the tubular smooth surface of carbon and elastomeric threads consists of loops formed by simultaneously knitting carbon 10 threads and 11 elastomeric threads forming an elastic frame.

Elastic tubular knitwear by weaving a tubular surface from simultaneously knitted carbon 10 and elastomeric 11 threads is obtained on a class 6 flat-wing machine, by weaving a tubular surface by turning off lying culinary wedges crosswise. The tension when feeding the carbon filament into the loop-forming system is 4.1 N, and the elastomeric filament is 15.4 N with a culling depth of 3.4 mm.

The cartridge for cleaning liquid works as follows: the cartridge is mounted in the seat of the filter holder. The filtered fluid supplied to the filter holder body passes through the supporting element 8. The cleaned fluid passes through the outer layer of the protective material 4, sorption-filtering material 2, where electrokinetic occurs in the inner sorption layer 3

the retention of negatively charged particles - bacteria and viruses, and the inner layer of the protective material 4. The layers of protective material 4 provide additional cleaning of the liquid due to the density of the extremely dense loop structure of the knitwear provided by the framework of the elastomeric 11 threads and carbon 10 threads, providing additional sorption cleaning liquids.

Then, through the perforated frame 1, the liquid to be cleaned enters the space between the frame 1 and the glass 5. Through the holes in the lower part of the glass 5, the liquid passes inside the glass 5 from the bottom up through the load from the heavy metal sorbent 6, then it passes to the consumer through the outlet of the filter holder.

An example of the manufacture of a cartridge for cleaning liquid.

A sorbent of heavy metals 6 is loaded into a glass 5 made with holes in the lower part. As a sorbent of heavy metals, for example, aluminum oxide monohydrate modified with nanosized particles of iron oxides can be used to remove iron, arsenic, cadmium, lead and manganese ; a mixture of ground zeolite, iron hydroxide and nanophase boehmite - for cleaning from arsenic, chromium, cadmium, copper and lead, modified humic acids for cleaning from iron, chromium, manganese, cobalt, zinc, titanium, nickel and copper, sorbents based on magnesium hydroxides , iron and aluminum - for cleaning copper, cadmium, zinc and lead.

A perforated element made of polymer material 7 is mounted on top of the sorbent of heavy metals 6. A glass 5, loaded with a sorbent of heavy metals 6, is placed inside the perforated frame 1, coaxially with it, with the formation of a gap between their cylindrical surfaces. The perforated frame 1 can be made of polyethylene, polyamide, polypropylene or other food grade thermoplastics. Separately prepare the sorption-filtering material 2, made in the form of a "sandwich", with an internal sorption

a layer 3 placed between two layers of protective material 4. The sorption layer 3 can be made of sorption material based on particles of alumina hydrate modified by a non-woven polymer fibrous material with a fiber diameter of 1-3 μm, or based on a Petryanov filter brand-15-2, 0, which is a uniform layer of ultrafine fibers with an average diameter of 1.5 microns deposited on gauze. The protective material 4 is made in the form of an elastic tubular knitwear from simultaneously knitted carbon and elastomeric threads.

A multi-layer filter material in the form of a cylindrical roll is formed from a sorption-filtering material 2 made in this way, by winding it in at least two layers.

A support element 8, for example, a polymer mesh, is put on a sorption-filter material 2 with an inner sorption layer 3 and layers of a protective material 4 (i.e., a multilayer filter material formed as a cylindrical roll) to provide additional protection against sagging or damage to the sorption material. After that, using the end parts 9 fix all the "layers" of the cartridge. The ready-to-use cartridge is mounted in the seat of the filter holder.

The filtered fluid supplied to the filter holder body passes through the supporting element 8. The cleaned fluid passes through the outer layer of the protective material 4, sorption-filtering material 2, where in the inner sorption layer 3 electrokinetic retention of negatively charged particles - bacteria and viruses, and the inner layer protective material 4, providing additional sorption cleaning of the liquid. Through the perforated frame 1, the liquid to be cleaned enters the space (gap) between the frame 1 and the cup 5, from where through the holes in the lower part of the cup 5

the liquid passes inside the glass 5 from the bottom up through the load of the sorbent of heavy metals 6, then through the outlet of the filter holder to the consumer.

Thus, the implementation of the layers of protective material in the form of elastic tubular knitwear by weaving the tubular surface from simultaneously knitted carbon and elastomeric yarns can increase the productivity of the filtering process and increase the degree of liquid purification.
