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 an element connected by end parts [US 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 the cartridge for cleaning the liquid contains a coaxially mounted beaker loaded with a sorbent of heavy metals, a sorption-filtering material, including two layers of protective material containing elastic tubular knitwear, and a multilayer sorption material placed between them, connected by end parts, while 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 tubular knitwear, floor knitted by simultaneously knitting inextensible and elastomeric yarn with a combined weave based on a two-layer with rows of smoothness knitted on both sides of the knitwear.

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, obtained by simultaneously knitting inextensible and elastomeric threads by combined weaving on the basis of two-layer with rows of smoothness knitted on both sides of the knitwear, except for cleaning the liquid due to the dense loop structure knitwear, provides, due to the rubber part of the rubber-textile material, additional cleaning due to the retention of small mechanical FIR particles and hydrocarbon compounds in the water and its own structural rigidity of the cartridge and the protective material generally functions perforated frame and a backing member provides resistance to fluid flow cartridge design.

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 cleaning liquids, FIG. 2 shows a graphical record of a combined weave based on a two-layer with rows of smoothness knitted on both sides of a knitwear.

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 tubular knitwear 6, obtained by simultaneously knitting inextensible 7 and elastomer oh 8 yarns weave combined based dvulastika (I and III) with rows coats (II and IV), vvyazannoy knitted on two sides 6 and porous rubber layer 9 on the underside of the knitted fabric 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 tubular knitwear 6 is obtained on an Interlock class 20 double-knitted circular knitting machine by simultaneously knitting an inextensible thread 7 and an elastomeric thread 8 by combined weaving on the basis of two-elastic (I and III) with rows of smoothness (II and IV) knitted on both sides of the knit.

In row I, the interlacing of the eraser 1 + 1 is connected. In row II, a smooth weave is knitted, the loops of which are located on the front side of the knitwear. In row III - the interlacing of the eraser 1 + 1 is repeated. In row IV - the surface is knitted, the loops of which are located on the wrong side of the knitwear.

On the wrong side of the elastic tubular knitwear 6 by the method of two-phase atomization followed by heat treatment, a rubber mixture is applied, from which a porous rubber layer 9 is formed, together with elastic knitwear 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 the electrokinetic retention of negatively charged particles - bacteria and viruses, and the inner layer of the protective material 4 The layers of protective material 4 in this case provide additional purification of the liquid due to the high density of the loop structure of the elastic tubular knitwear 6 and after It performs on its wrong side of both layers of protective material 4 (facing the multilayer sorption material 5) a porous rubber coating 9, which, in addition to cleaning the liquid by retaining small mechanical particles and hydrocarbon compounds in the water, 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 layer of which is made in the form of a duplicated rubber-textile material, with the outer side of an elastic tubular jersey obtained by simultaneous knitting of inextensible and elastomeric threads with a combined weave on the basis of a two-layer with rows of smoothness knitted on both sides of the knitwear, and placed I am waiting for them multilayer sorption material connected by end parts, provides an increase in the degree of purification of the liquid while simplifying the design of the cartridge.
