Description

The utility model relates to devices for purifying liquids by filtration using a sorption process and can be used in process water treatment systems for various industries, for domestic use, as well as in the field.

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 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.

A known cartridge for cleaning liquid, containing a perforated frame formed around it in several layers of sorption-filtering material, comprising at least two layers of protective material and placed between them a multilayer sorption material, a supporting element worn over the sorption-filtering material and a glass loaded with a sorbent of heavy metals, mounted inside and on the same axis with a perforated frame, connected by 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.

Known cartridges for cleaning liquid, containing 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 a supporting element made of elastic tubular knitwear by combined weaving of an eraser 1 + 1 from simultaneously knitted inextensible and elastomeric threads, in which broaches of adjacent loops of inextensible threads are located laid between the looped columns of the front and back sides, and the surface knitted on the front side of the eraser in 10 looped rows of inextensible threads [Pat. RU 171495, IPC B01D 27/02, 02/02/2017] and a supporting element made of elastic tubular knitwear with a combined weaving of an eraser 3 + 1 from simultaneously knitted inextensible and elastomeric threads and smoothness, knitted on the front side of the eraser in 10 looped rows of inextensible threads [Pat. RU 171023, IPC B01D 27/02, C02F 1/28, C02F 101/20, C02F 103/04, 05.17.2017] connected by end parts.

The disadvantages of these devices are their low efficiency when cleaning from organic compounds and petroleum products, as well as low mechanical resistance of the supporting element to the strong pressure of the treated water.

The closest in technical essence and result to the proposed device is a cartridge for cleaning liquids, containing a coaxially mounted glass with loading from a sorbent of heavy metals, a perforated frame, sorption-filtering material, comprising at least two layers of protective material, made in the form of an elastic tubular knitwear by weaving a tubular surface of simultaneously knitted carbon and elastomeric filaments and a multilayer sorption material placed between them, and supporting lement connected end piece [Pat. RU 155031, IPC B01D 27/02, 09/20/2015].

The disadvantage of this device is its low efficiency when cleaning from organic compounds and petroleum products.

The objective of the proposed technical solution is to develop a cartridge resistant to strong fluid flows with the possibility of additional purification from organic compounds and petroleum products.

Effect: increase the degree of purification of the liquid.

The technical result is achieved by the fact that in a cartridge for cleaning a liquid containing a coaxially mounted beaker loaded with a heavy metal sorbent, a sorption-filtering material comprising two layers of protective material containing elastic tubular knitwear, and a multilayer sorption material placed between them, connected by end parts wherein the layers of protective material are made in the form of a duplicated rubber-textile material, the outer side of which is made of elastic knitwear in the form of joint stno knit loops of a chain of non-extensible yarns and loops of tricot spandex elastomeric threads.

The execution of both layers of protective material in the form of a duplicated rubber-textile material, the outer side of which is made of elastic knitwear in the form of jointly knitted chain loops of inextensible threads and tricot loops of elastomeric yarns, spandex, in addition to cleaning the liquid due to the dense knitted structure of the knit, provides, due to the rubber parts of rubber-textile material, additional cleaning due to the retention of small mechanical particles and hydrocarbon compounds in water and the new rigidity of the design of the protective material and the cartridge as a whole, performing the functions of a perforated frame and a supporting element, which provided resistance to the design of the cartridge to fluid flow.

As a result of this, the degree of purification of the liquid is increased and the device of the cartridge is simplified.

In this case, the layers of the protective material do not impede the passage of the liquid being cleaned, act as a filter from mechanical impurities and a filter from hydrocarbon compounds, 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 chain loops of inextensible threads; in FIG. 3 is a graphical representation of the hinges of spandex elastomeric threads.

The liquid cleaning cartridge contains a coaxially mounted glass 1 loaded with a heavy metal sorbent 2, a sorption filter material 3 in the form of a cylindrical roll, which is made of two layers of protective material 4 and a multilayer sorption material placed between them 5. Each layer of protective material 4 made in the form of a duplicated rubber-textile material, the outer side of which is made of elastic knitwear 6, obtained by jointly knitting chain loops from inextensible threads 7 and p A leotard made of spandex elastomeric yarns 8 and a porous rubber layer 9 on the wrong side of knitwear 6.

On top of the load 2, a retaining perforated element 10 of polymer material is mounted.

The end parts 11 located at the ends of the cartridge fix all its layers and serve to attach the cartridge to the filter holder.

Elastic knitwear 6 is obtained by combining loops of various weaves in one loop, namely a combination of chain stitches from inextensible strands 7 and leotard loops from elastomeric yarns 8 spandex.

An elastic knitted fabric is knitted on a warp knitting machine using two combs. The first comb is dressed with inextensible thread 7 and carries out the laying of chain loops through one needle. The second comb is dressed with spandex type 8 elastomeric thread and carries out the laying of tights loops. The obtained elastic knitted fabric is connected on an Overlock machine along the fabric to form a tubular elastic knit.

On the wrong side of the elastic knitwear 6 by the method of two-phase spraying followed by heat treatment, a rubber mixture is applied, from which a porous rubber layer 9 is formed, together with the elastic knit 6 forming a rubber-textile material.

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 sorption-filtering material 3: the cleaned liquid passes through the outer layer of the protective material 4, the intermediate multilayer sorption material 5, where electrokinetic retention of negatively charged particles of bacteria and viruses, and the inner layer of the protective material 4 .

The layers of the protective material 4 in this case provide additional cleaning of the liquid due to the high density of the loop structure of the elastic knitwear 6 and due to the execution of both layers of the protective material 4 (facing the multilayer sorption material 5) on its seamy side of the porous rubber coating 9, which, in addition to cleaning the liquid, due to the retention of small mechanical particles and hydrocarbon compounds in water, it provides mechanical protection of the multilayer sorption material from damage.

Then, through the sorption-filtering material 3, the liquid to be cleaned enters the space between the sorption-filtering material 3 and the glass 1. Through the openings in the lower part of the glass 1, the liquid enters the glass 5 and passes from the bottom up through the load from the sorbent of heavy metals 2, then through the outlet of the filter holder purified liquid leaves the cartridge.

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

A sorbent of heavy metals 2 is loaded into a glass 1 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 holding element 10 is installed on top of the sorbent of heavy metals 2. A glass 1, loaded with a sorbent of heavy metals 2, is placed inside a separately prepared sorption-filtering material 3 (made in the form of a “sandwich”, with an internal sorption layer 5 placed between two layers of protective material 4), coaxially with it, with the formation of a gap between their cylindrical surfaces.

The sorption layer 5 can be made of a sorption material based on particle-modified alumina hydrate of a non-woven polymer fibrous material with a fiber diameter of 1-3 μm, or based on a Petryanov filter-15-2.0 filter, which is a uniform layer of ultra-thin fibers with an average diameter 1.5 microns deposited on gauze. The protective material 4 is made in the form of rubber-textile material from an elastic tubular knitwear 6 and a porous rubber coating 9 formed on its wrong side.

After that, using the end parts 11, all “layers” of the cartridge are fixed. The ready-to-use cartridge is mounted in the seat of the filter holder.

Thus, a cartridge for cleaning liquid, containing a coaxially mounted beaker loaded with a sorbent of heavy metals, a sorption-filtering material comprising two layers of protective material, each of which is made in the form of a duplicated rubber-textile material, the outer side of which is made of elastic knitwear in the form of knitted loops of a chain of inextensible filaments and tricot loops of elastomeric spandex yarns, and a multilayer sorption material placed between them, connected by end etalyami, enhances the degree of cleaning fluid cartridge while simplifying construction.
