DEVICE FOR ELECTROCHEMICAL CLEANING OF DRINKING WATER

(utility model)

The proposed utility model relates to the field of drinking water supply., Specifically, to devices for the electrochemical treatment of drinking water and can be used in domestic conditions for the purification of tap water, as well as for the purification of natural waters and bringing the physicochemical and organoleptic properties to meet the requirements for drinking water.

Household water purifiers based on sorption and membrane processes are known. Their disadvantages are: the accumulation of harmful impurities in the device with their subsequent release into the treated water (the law of concentration equilibrium), deionization of water.

Electrochemical methods allow the most effective purification of water from anthropogenic impurities (Miklashchevsky N.V., Korolkova S.V. Pure water. Purification systems and household filters. St. Petersburg: VHV - St. Petersburg, published. Arlit Group, 2000, p. 154).

A device is known that implements the method of electrochemical purification of drinking water according to patent RU 2043308, comprising a container in which a package of electrodes with a soluble anode is placed, as well as a container with a filter element. The device also contains a power and control source with a step-down transformer and a rectifier connected to the AC network and to the electrodes of the device.

The specified device for the maximum number of similar essential features (capacity with a package of electrodes with a soluble anode, capacity with a filter element) are taken as a prototype of a utility model.

The disadvantage of the device selected for the prototype are: low removal efficiency of the sludge collected at the neck of the container with a package of electrodes, the excess of sludge remaining in the reactor vessel on the filter element and a significant reduction in its resource.

MKI with 02 F1 / 46

The purpose of this technical solution is to increase the efficiency of removing sludge from the reactor vessel and, as a result, improve the operational characteristics of the device (accelerate the coagulation process, increase the resource of the filter element).

The essence of the proposed technical solution lies in the fact that in the upper part of the vessel containing the electrode package, a easily removable return cone with a bucket located in the center of the cone with a vertical handle for extracting the cone from the reactor is installed with the possibility of vertical movement.

In addition, the device is equipped with a funnel, at the exit of which there is fixed a permanent ring magnet with a magnetic field of 500 to 1500 Oersted, and the filter capacity is equipped with a light-weight filter element., Zg.

The introduction of these signs into the device accelerates the coagulation process by magnetic treatment of water when filling the reactor vessel before subsequent electric processing. The coagulant formed, flotating to the surface, is arranged in the form of a ring in the space between the wall of the reactor vessel and the inverse cone. After the coagulant flakes have ripened, this cone is pressed by pressing a vertical handle into water to a depth of three cm from the surface. In this case, all sludge located outside the base of the inverse cone, as a result of squeezing out water, enters the specified cone with part of the purified water, after which the cone together with the sludge collected in it is removed from the reactor vessel, the waste is dumped, and the cone is washed inside and out. The purified, sludge-free water is poured from the reactor vessel into the filter vessel and filtered water is supplied to the consumer.

From the prior art, no solutions have been identified that have signs that match the distinctive features of the proposed technical solution. Therefore, we can assume that the proposed technical solution corresponds to the level of the utility model.

The essence of the proposed technical solution is illustrated by graphic materials, where in FIG. 1 shows a diagram of a prototype device, FIG. 2 is a structural diagram of the proposed device, in FIG. 3 - the position of the inverse cone-pshamosbornik in the reactor vessel after the end of electrochemical processes (electroflotocoagulation and settling flotation), FIG. 4 illustrates the process of extracting sludge from the reactor vessel with a pump; by a cone-sludge collector, in FIG. 5 schematically shows a filter element.

The proposed device (Fig. 2) also as a prototype (Fig. 1) contains a power supply and control 1, the capacity of the reactor 2 with a package of electrodes 3.

Unlike the prototype, in the proposed device, in the upper part of the vessel of the rector 2 is installed with the possibility of vertical movement with buoyancy (washed from above easily removable inverse cone 6 with a vertical handle 7.

The buoyancy of the inverse cone is designed so that when it is immersed in water, the water level will be no more than 5-6 mm below the upper boundary of the inverse cone.

In addition, the proposed device is reduced by a funnel 8, on the drain tube of which an annular magnet 9 is fixed, having a magnetic tension of from 500 to 1500 Oersted.

It is known that a magnetic field effectively accelerates the coagulation process (Klassen. Water n magnet. 1968).

The operation of the device.

From the tank of the reactor 2, the reverse coius 6 is removed for the vertical handle 7. A funnel 8 with a ring magnet 9 is installed on the tank of the reactor 2 and the reactor tank is filled with feed water through it to a level 3-4 cm below the edge of the reactor. The funnel 8 is removed and the inverse cone 6 is replaced. The power supply 1 is turned on to an alternating current network (220 V, 50 Hz), a rectified current (12-36 Volts) is supplied to the electrode package 3. The cathodes of the electrode stack release electrolytic hydrogen into the treated water, and the anode dissolves, releasing ions (usually aluminum). Aluminum hydroxide is formed, which coagulates, sorbing harmful impurities from the water, and in the form of flakes rises (floats) under the action of electrolytic hydrogen bubbles to the surface and is located in the ring between the wall of the reactor vessel 2 and the base of the inverse cone 6,

At the same time, atomic oxygen is formed on the anode, which actively oxidizes organic impurities and disinfects water, and unreacted oxygen atoms recombine into oxygen puffs and, together with electrolytic hydrogen, contribute to the electroflotation process.

After the calculated time of the electric processing, the power source 1 automatically disconnects the package of electrodes 3, and a settling process proceeds in the vessel of the reactor 2. Since the treated water at the same time contains the smallest poofs of electrolytic hydrogen and oxygen, the process is accompanied by flotation. As a result, almost all coagulant flakes (sludge) are collected at the neck of the reactor vessel 2 in the ring between its wall and the base of the inverse cone 6 (Fig. 3).

After exposure of the sludge (all the sludge is collected in the ring), by pressing the vertical handle 7 of the cone 6, immerse the inverse cone to a depth of 2-3 cm (Fig. 4). In this case, a certain volume of treated water is squeezed out together with the sludge and discharged into the container of the cone 6. Upon completion of the discharge, the return cone 6 is removed from the vessel of the reactor 2, the cones are drained and washed with running water.

Water from the reactor vessel 2 is poured into the filter vessel 4, where it is filtered through the filter element 5 and is supplied to the consumer. The filter element is made in the form of a torus (Fig. 5, pos. C) by deformation of the cylinder (Fig. 5, pos. A) wound from polypropylene fiber. The cylinder washer so that the cylinder does not collapse upon deformation, and the possibility the shift of the base of the cylinder, made in the form of convex and concave cones (figure 5, pos. b), provides a reliable docking of these cones with each other when tying the cylinder into a torus. Thus obtained filter element on the outer surface of the torus has a more "loose structure (Fig. 5, pos. B1) and delays larger micro suspensions, and on the inner surface of the torus has a denser structure (Fig. 5, pos. B2) and delays the smallest micro suspension.

After releasing the capacity of the reactor 2, the process is repeated with the next portion of the source water.
