Description

The utility model relates to the field of applied electrochemistry, in particular to portable devices for electrochemical treatment of water with the aim of directionally changing its properties and can be used by a wide range of individual consumers in domestic conditions.

Electrochemical activation as a physicochemical process is a combination of electrochemical and electrophysical effects on water with the ions and molecules of dissolved substances contained in it in the space charge region at the electrode surface. The redox potential (ORP) of cathode water can reach -800 mV. Thus, without any chemical additives, while maintaining full biocompatibility, water turns into an effective antioxidant and biostimulant. The ORP of anode water reaches +1000 mV and, on the contrary, it becomes a strong oxidizing agent and has a bactericidal effect. (Bakhir V.M. et al. Electrochemical activation: history, state, prospects. - M.: АМТН RF, VNIIIMT, 1990).

Known devices for the electrochemical activation of water containing a body of dielectric material, divided into two chambers, in the chambers are anode and cathode. (SU A.S. No. 1171428 A, C02F 1/46, 08/07/1985; RU Patent No. 2148029, C02F 1/461, С25В 13/00, 04/27/2000; RU Patent No. 2178773, C02F 1/46, 27.01. 2002; RU Patent No. 2287491, C02F 1/46, 11.20.2006). The disadvantage of the devices is the inconvenience of using them in domestic conditions, insufficient quality of water treatment, increased energy consumption, as well as the use of electrodes, which, although not significantly, dissolve, polluting the catholyte and anolyte with harmful impurities.

A device for the electrochemical treatment of water and aqueous solutions is known (RU Patent No. 2204530, C02F 1/461, 05.20.2003). The device comprises a body of dielectric material with a block of two electrodes made of titanium coated with ruthenium dioxide, and a diaphragm is located between the electrodes, which separates the interelectrode space into the cathode and anode chambers, with channels for separate removal of catholyte and anolyte from the chambers. The electrodes are cylindrical, mounted coaxially. The diaphragm is coaxial to the electrodes and made of cylindrical ceramic based on aluminum and zirconium oxides. Quick disconnect mounted

hydraulic connections and electrical connector. The disadvantages of the device are the difficulty of connecting and operating in a domestic environment, as well as the high cost of the apparatus, due to the high cost of manufacturing. This device is taken as a prototype.

The objective of the utility model is the development of a portable, low cost, easy to connect and maintain, safe apparatus for receiving catholyte and anolyte with metastable properties from domestic water,

The technical result achieved in the utility model is to simplify and cheapen the design of the apparatus without compromising the quality and degree of activation of catholyte and anolyte.

The proposed electrochemical water activator, as well as the prototype, contains a body of dielectric material with a block of two electrodes made of titanium coated with ruthenium dioxide and a diaphragm installed between the electrodes and dividing the interelectrode space into the cathode and anode chambers with channels for Separate removal of catholyte and anolyte from chambers.

Unlike the prototype, a rotameter tube is installed on the casing, connected to the water inlet fitting, and the diaphragm is made of a track membrane protected by a tarp on both sides.

The presence of a tube-rotameter allows you to control the overall performance of the device. The implementation of the diaphragm from the track membrane allows you to prevent the mixing of the products of electrode reactions, and reduce energy consumption for water treatment, due to the low intrinsic electrical resistance.

In order to simplify the manufacture of the device, the electrode block is made plane-parallel and pulled together with studs.

A membrane cartridge is connected to the input inlet of the source water, which allows to clean the source water from mechanical impurities and iron.

In addition, the catholyte and anolyte exit channels are equipped with special adjusting screws, which allow the apparatus to be controlled separately for catholyte and anolyte.

In the future, the essence of the proposed utility model is illustrated by a description of a schematic representation of the electrochemical activator in figure 1 and an example of a specific work.

The electrochemical water activator for producing activated catholyte and anolyte consists of a diaphragm electrolyzer, which is a block of

pressure plates 1 made of organic glass. The plates have channels for supplying tap water to the working cathode and anode chambers and for removing catholyte and anolyte. In the plates, recesses are made to accommodate the electrodes (cathode 2 and anode 3). The plates are compressed with studs 4 and hermetically seals the electrodes 2, 3 and the working chambers 5 with a diaphragm 6 placed between them, which eliminates overhead leakage and provides double isolation of dangerous voltage. The assembled cell unit is placed in the housing 7 of a dielectric material (for example, polystyrene). Tap water is supplied through a silicone tube 8 through a membrane cartridge 9 made, for example, from a track membrane. A rotameter tube 10 is connected to the water inlet fitting. The output channels of the catholyte and anolyte are equipped with adjusting screws 11, which compress the silicone tube and allow separate control of the catholyte and anolyte performance. The electrochemical activator is powered from a household 220 V AC network through a diode 12, a button with a latch 13 and a fuse 14. Power is supplied to the electrodes through current leads 15. The indicator light 16 indicates the current is turned on. The entire electrical circuit is located inside the housing 7, from which it is connected power cord plug.

The electrochemical activator operates as follows. The silicone inlet tube 8 is connected to a water tap by means of an adapter, also included in the set of the device. The faucet is gradually opened until the water in the tube-rotameter 10 is established between two marks fixing the performance of the activator. At this time, the original tap water passes through the membrane cartridge 9, where it is cleaned of mechanical impurities and iron, and through the channels in the pressure plate 1 enters the lower part of the working chambers 5, then passes upward along the electrodes and diaphragm. Through the output channels, water leaves the apparatus and pours into the substituted containers (glasses). When the water flow is set according to the marks of the tube-rotameter 10, the power plug is plugged into the power outlet and the “On / Off” button 13 is pressed. At the same time, the indicator light 16 “Network” lights up, from then on the water in the device is processed. To establish a permanent treatment regimen, wait 2–3 minutes, then drain the water from the installed containers and proceed with the selection of catholyte and anolyte. By means of adjusting screws 11, approximately equal flow rates of catholyte and anolyte are set.

As an example, consider a working electrochemical activator for producing activated solutions of catholyte and anolyte from tap water with a catholyte productivity of 4 ÷ 5 l / h and anolyte of 3 ÷ 4 l / h. Consumable

power 60 watts. Dimensions 60 × 120 × 190 mm. The electrodes are made of titanium coated with ruthenium dioxide (ORTA), and the diaphragm is made of two layers of tarpaulin, between which a track membrane is laid. The working areas of the electrodes and the membrane are the same in size and equal to 33 cm ² . The working chambers are made of polystyrene with a thickness of 4 mm.

The source water from a tap, having a redox potential (ORP) of + 150 ÷ + 300 mV and a pH of 7.0 ÷ 8.2, is fed through a membrane cartridge into an electrochemical activator. The input water flow is set by red marks on the tube-rotameter. The device is turned on by connecting the power cord to an outlet and pressing the “On / Off” button. The “Network” indicator light comes on. Using the adjusting screws, the catholyte consumption is set at 5 l / h, and the anolyte - 4 l / h. 2 minutes after switching on, the receiving tanks are emptied, and the selection of activated catholyte and anolyte begins. In the catholyte and anolyte obtained, the acidity (pH) was measured using a pH 2 instrument and the redox potential (ORP) using an HI 98201 instrument. The obtained pH and ORP values are summarized in Table 1.

Table 1 An object Productivity, l / hour pH ORP, mV Tap water 9 7.6 +250 Catholyte 5 10,2 -360 Anolyte four 6.8 +720 Catholyte 4,5 10.6 -430 Anolyte 4,5 7.0 +770 Catholyte four 10.8 -520 Anolyte 5 7.3 +840

As can be seen from table 1, with a tap water productivity of 8 ÷ 10 l / h, limited by red marks on the rotameter, judging by the value of the ORP, highly active catholyte and anolyte are obtained without any chemical additives. Since, during the electrochemical treatment of water, metastable radicals with a short lifetime are formed in the solution, the catholyte and anolyte tend to return to their original state over time. Table 2 shows the dependence of the ORP value on the exposure time after processing.

table 2 Holding time ORP of catholyte, mV ORP anolyte, mV 0 -580 +750 10 min -480 +755 20 minutes -400 +747 30 minutes -380 +740 1 hour -350 +732 1,5 hour -300 + 727 + 725 2 hours -280 +725 2.5 hours -270 +722 3 hours -260 +718 4 hours -240 +716 5 o'clock -210 +714 6 o'clock -190 +712 10 hours -150 +709 15 hours -95 +706 20 hours -10 +700 24 hours +85 +690

As can be seen from table 2, the oxidative properties of the anolyte change very slowly. During the day, the anolyte AFP decreased slightly. At the same time, the catholyte relaxes very quickly and after a day its ORP goes into the positive region, i.e. restoration properties of catholyte disappear. Immediately after processing, the negative ORP of the catholyte decreases sharply, which is explained by the short lifetime of some radicals. Within 30 minutes, the negative ORP of catholyte decreases by almost 2 times, and the further change is smoother. Hence, it is advisable to use the catholyte derivative fresh for 30 minutes and, in extreme cases, with an exposure of up to 4–5 hours. Anolyte retains its properties for up to 3 days.

The proposed utility model of an electrochemical activator of water is an effective, easy to manufacture and maintain, relatively cheap and safe to use device for producing activated solutions of catholyte and anolyte.
