Description

The utility model relates to water purification systems that are consumed from the city water supply network, pump rooms and other sources of drinking water, in particular, it relates to automatic machines for producing purified drinking water that meets physiological requirements for mineral composition and can be used at various decentralized water supply facilities and collective use of drinking water.

It is well known that the quality of drinking water that is prepared from the surface waters of rivers, ponds or groundwaters at central water supply stations does not fully meet the requirements of sanitary-hygienic standards [1] and therefore requires additional treatment in places of direct water consumption by the population, for example, in machines for obtaining purified drinking water.

A known system that provides the purification of drinking water and which has inlet and outlet nozzles, one or more sequentially installed filter modules, an inlet fitting connected to a pressure reducing valve (RU, 2413569). A counting and locking unit with an indication device for the amount of purified water is installed at the inlet, which at the end of the treatment of a certain amount of water blocks its movement.

The disadvantage of this system is that it does not provide complete purification of water and its disinfection of harmful microorganisms.

A known installation with a water purification system, which consists of a means for supplying source water, a pressure reducer, series-connected membrane flow filters with fittings for draining purified and uncleaned water installed between the membrane filters of the cartridge with a sorbent-absorber, while the first in the direction of travel the water filter has a filter element with a pore size of more than 1 μm, and the second filter has a filter element with a pore size of less than 1 μm and its fitting for draining the purified water is connected to the faucet Lenia purified water (RU, 2196632).

The disadvantage of this installation is that it does not provide for the repeated purification of water and its disinfection from microorganisms and it is impossible to accurately dispense the dispensing of purified water, that is, its use in drinking water selling machines.

The closest in technical essence to the utility model, which is claimed, is an automatic machine for producing purified drinking water, consisting of a means for supplying water, a pressure reducer with a built-in filter, which is connected to sequentially installed flow filters, a "structure torus" of water, a mineralizer, device for ultraviolet disinfection of water. In addition, such a machine is equipped with an electronic control unit, a payment receiver and a display, providing bottling and sale of purified water. (UA, 63220).

The disadvantage of this known utility model is that it purifies water only from mechanical impurities whose size exceeds 0.45 microns, while in the tap, artesian and other natural sources of water, the vast majority of impurities, including those harmful to human health, contained in a dissolved state and need to be treated [2].

Another disadvantage is that this system provides for the use of the own pressure of the water supply source, which limits the industrial applicability of this known utility model, since the specific consumption and quality of the treated water depends on the pressure.

A disadvantage of the known utility model is also the design of the mineralizer that it contains. Mineralizer is a vessel with specially selected minerals that gradually dissolve in water. This design of the mineralizer is not able to provide a constant ionic composition of the treated water, since the solubility of the minerals used in it depends on the type of mineral, pH and the redox potential of the treated water, and a number of other factors.

The disadvantages of the known utility model, under certain conditions, can also be attributed to the presence of a “structurer” of water in its design, which contains permanent magnets, which allows them to remove all the negative information that has been accumulated in the water. According to recent scientific studies [3], the fact of the accumulation of any information by water is unproven, metrological means and devices for measuring these phenomena are not available today, and some technical equipment offered on sale under the name “structurers” can harm human health through the release of various toxic impurities. In this utility model, the consumer is not given the opportunity to choose to purchase “structured” water or water that has not been exposed to such an impact.

The utility model is based on the task of improving the automatic machine for producing purified drinking water, which would allow drinking water with a high degree of purification of tap, artesian or other natural water, including from low-pressure water sources, from dissolved impurities, at the outlet of the machine and with a constant mineral composition that meets the modern requirements of physiological usefulness [4].

The problem is solved in that a reverse osmosis membrane module, an antiscalant dosing module and a high pressure pump, a permeate carbon filtration module and a pH correction module are introduced into the cleaning system in the claimed machine.

In the prevailing embodiments of the claimed machine, additional elements such as a permeate domineralization module or a permeate hydroaccumulator, which is designed to accumulate permeate exiting the reverse osmosis water purification module, and to supply this permeate to the carbon filtration module of the permeate, can be introduced into its composition. In addition, in the claimed machine it is additionally possible to introduce a dosed filling module for the obtained purified water into the consumer's container, which provides a metered supply of purified drinking water at the outlet of the inventive automatic machine to the consumer's container.

And finally, for the possibility of selling purified drinking water to the proposed machine, you can enter an electronic unit for controlling the dosage and receipt of payment in accordance with the established tariffs.

Further, the essence of the utility model is explained in a detailed description with reference to the drawings, where figure 1 shows the General scheme of the machine according to the utility model.

As shown in FIG. 1, the machine, which is claimed, consists of sequentially installed: module (1) for coal filtration of incoming water, pump (2) for high pressure, module (3) for reverse osmosis membrane water treatment, module (4) for coal filtration of permeate, module (5) for correction pH, module (6) of ultraviolet water disinfection and module (7) of dosed water dispensing into consumer containers, connected by corresponding pipelines 8, 9, 10, 11, 12, 13.

The machine also includes an antiscalant dosing module (14) (a substance that prevents the deposition of poorly soluble compounds on the membrane surface), which doses into the pipeline flow (8) between the carbon filter module (1) of the incoming water and the high pressure pump (2). In addition, this machine has a permeate hydroaccumulator (15), which accumulates the permeate exiting the reverse osmosis membrane water treatment module (3), and feeds it into the stream (10) to the permeate filter (4), as well as the module for mineralization (16) permeate, which delivers the mineralized water in it into the pipeline flow (13) between the ultraviolet disinfection module (6) and the dosed bottling module (7) of drinking water into the consumer's container.

Water trapped by the membrane of the reverse osmosis water treatment module (3) and containing soluble impurities (hereinafter referred to as the concentrate) is discharged into the sewer through a pipeline from which a pipeline (11) is connected to the pipeline (8) between the coal filter (1) of the incoming water and a high pressure pump (2).

The module (1) for coal filtration of the inlet water consists of carbon filters of the “carbon block” type or others.

The reverse osmosis water treatment module (3) can be of various designs, but it is preferable to use a module consisting of a membrane holder and a membrane element of size 4040 or another. The use of a membrane element of the Filmtec XLE type as a membrane element of a membrane module ensures the removal of 99% dissolved impurities from the purified water at a working pressure of 0.69 MPa and a water temperature of 25 ° C [5].

The high pressure pump (2) provides an operating pressure of 0.5 to 1.5 MPa, which is necessary for water purification by the reverse osmosis method, has a rated power of about 0.75 kW or another, and is connected to a 220 V power supply network.

The module (7) for dosed filling of the obtained purified water into consumer containers has a known design.

The reverse osmosis permeate domineralization module (16), which provides the composition of purified water that meets the physiological requirements of drinking water for mineral components, may consist of a metering pump for a remineralizing solution connected to a container (not shown) containing this solution.

A remineralizing solution, the ratio of the components of which is selected in accordance with the requirements of physiological usefulness of drinking water according to the mineral composition, is dosed into the reverse osmosis permeate stream in the pipeline (13), due to which this permeate is enriched with the necessary mineral components.

In addition, the machine can be used for the sale of drinking water and as part of such a machine can include a control module, dosing and receiving the appropriate payment (not shown). In addition, the claimed machine may include an electronic controller that monitors and controls the system, instrumentation and equipment (rotameters, manometers, pressure switches, signal converters), a control panel, coin and bill acceptors. Optionally, this module may have a reader of information cards and other storage media, a device for storing and processing information, a device for receiving and transmitting information according to GSM, CDMA, or other standards, sensors for a satellite navigation system, voice command reception devices, a touch control panel, security and fire alarm system.

The claimed machine operates as follows. Input water is supplied to the module (1) of coal filtration of the input water, where it is purified from mechanical impurities, high molecular weight organic substances and residual chlorine. Before water is supplied to the reverse osmosis water treatment module (3) by means of the antiscalant dosing module (14) into the water (pipeline (8)), the antiscalant is dosed to prevent deposits on the membrane surface in the reverse osmosis water treatment module (3). After that, water is supplied to the high pressure pump (2), where it acquires the pressure necessary for cleaning by reverse osmosis. In module (3) of reverse osmosis water treatment, water is divided into two streams - a stream of purified water (hereinafter referred to as permeate) entering the pipeline (10) and a stream of water containing dissolved impurities that were retained by the membrane (hereinafter the concentrate) entering the sewage pipeline . Part of the concentrate is sent through a pipeline (11) to the inlet of the reverse osmosis water treatment module (3) through a high pressure pump (2), i.e. recycled, and part is discharged into the sewer. Recycling of the concentrate is organized in order to reduce the volume of wastewater into the sewer and increase the hydraulic efficiency of the reverse osmosis water treatment module (3). The flow of permeate created in the reverse osmosis water treatment module (3) depends on the pressure provided by the high pressure pump (2) in the module (3). The permeate flow rate from the membrane of the module (3) is quite low and under low pressure. Therefore, permeate in a preferred embodiment of the claimed utility model is collected in a hydraulic accumulator (15) and fed via pipeline 10 to improve organoleptic properties to the carbon filtration module (4) of the permeate, and then to the pH correction module (5), where the alkalinity of the water increases. Further, through the pipeline (12), the processed permeate is supplied to the ultraviolet disinfection module (6), where the water is disinfected by ultraviolet radiation. After that, the permeate is fed through the pipeline (13) to the module (7) for dosed filling of the obtained purified drinking water into the consumer’s container, before undergoing pre-mineralization in the permeate domineralization module (16), which feeds into the pipeline (13) between the ultraviolet disinfection module (6) and module (7) remineralizing solution.

Thus, the water is purified to the level of current sanitary and hygienic standards and is enriched with mineral components to the level of physiological requirements for drinking water [4].
