Description

 The invention relates to devices for the electrical treatment of liquids used for a bacterium and sporocidal medium as a catalyst, process liquid, etc., and may find application in food, pharmaceutical, light and other industries.

 A known design of the electrolytic cell VF-500 for water, containing a set of electrolysis cells with electrodes and membranes between them [1] The disadvantage of the design is the presence of remote electrodes, remote channels for anolyte and catholyte, a large specific gravity.

 The closest known device (prototype) is a device for electrical processing of liquids containing a package of flat electrodes separated by ion-permeable membranes with inlet and outlet pipes, channels for supplying and discharging liquid with dispensers for supplying liquid to each cell and draining it from each cell [ 2] Design disadvantages are: a large specific gravity of the device, the impossibility of accurately centering the holes forming channels for anolyte and catholyte, leakage of liquid at the borders of adjoining to each other the elements of the package of cells.

 The problem solved by the invention is to ensure the safety of the device, ease of manufacture and operation, reducing the specific gravity of the device.

 To solve this problem, in a device for electroactivation of liquids containing a set of cells between end plates, including flat electrodes with insulating spacers and ion-permeable membranes placed between them, and devices for input and output of the processed liquid, a cavity is made in the left end plate, on the right end plate - protrusion. A hollow and a protrusion are made on the inner frames, separated by a partition, while the cells are formed by one of the end plates and the adjacent inner frame, or two adjacent inner frames. Flat unipolar electrodes are melted in the surface of the hollow of the left and protrusion of the right end plates, and bipolar electrodes made in the form of an endless ribbon and fused into the surfaces of the hollows and protrusions of the inner frames are passed through slots in the partitions of the inner frames. Devices for introducing and discharging the processed fluid into the cells are made in the form of channels placed in the body of the inner frames and end plates, and holes in the insulating gaskets.

 The set of essential features set forth in the claims, allows for accurate centering of the holes that form the channels for input and output of the treated fluid, eliminate leakage of electrolyte through leaks in the package, reduces the weight of the device.

 The exact centering of the holes forming the channels for the anolyte and catholyte is ensured by strict fixation of the elements of the packet of cells relative to each other by connecting them with the help of the protrusions entering the troughs of the neighboring cell elements and made with precision, ensuring the alignment of the holes.

 Leakage of fluid along the boundaries of the junction of cells is eliminated by the fact that the cell elements (gaskets, membrane and electrodes) are located inside the cavity and are “locked” by the corresponding protrusion. Thus, between adjacent cells there is only one external gasket worn on the protrusion, which completely eliminates the leakage of fluid from the cell.

 The specific gravity of the device (i.e., the mass per unit volume of activated water) is reduced due to the implementation of end plates and internal frames of plastic, which simultaneously increases the electrical safety of the device.

 In FIG. 1 shows a general view of a device for electroactivating liquids; in FIG. 2 construction of an internal frame with a bipolar electrode; in FIG. 3 - construction of the left, and in FIG. 4 right end plates with unipolar electrodes.

 The device (Fig. 1) contains a set of cells. The cell is formed by one of the end plates of the left 1 or right 2 and the adjacent inner frame 3 or two adjacent inner frames 3. Each cell includes two electrodes: unipolar 4 or 5 and bipolar 6, or two bipolar electrodes 6; two rubber inner gaskets 7, between which is an ion-permeable membrane 8; an external rubber gasket is placed between two adjacent cells 9. The packet of cells is clamped with ties 10. The end plates, internal frames and external gaskets have openings that form channels for the movement of the anolyte and catholyte together with the gases released during electroactivation. In addition, there are openings in the end plates, internal frames and external gaskets for passing screeds through them. To ensure consistent movement of the anolyte and catholyte through all the cells, individual sections of the channels are plugged with plugs 11. The input liquid is introduced into the device for the anolyte and catholyte through pipes 12 and 13, respectively; and the withdrawal of anolyte and catholyte through pipes 14 and 15, respectively.

 Each inner frame (Fig. 2) has a depression and a protrusion separated by a partition in which two slots are made; a bipolar electrode, which is an endless ribbon, is passed through them. The bipolar electrode is fused to the surface of the cavity and protrusion.

 The left end plate (Fig. 3) has only a cavity, into the surface of which the left unipolar electrode is fused, equipped with a contact brought out of the upper part of the plate beyond its limits.

 The right end plate (Fig. 4) has only a protrusion, into the surface of which the right unipolar electrode is fused, provided with a contact brought out of the upper part of the plate beyond its limits.

 Slots in the inner frame and end plates melt after placement of electrodes in them.

 The inner gaskets 7 (Fig. 1) with the ion-permeable membrane 8 located between them are laid in the hollow of the left end plate 1, or the inner frame 3 and are compressed by the protrusion of the adjacent inner frame 3 or the right end plate 2 entering the cavity, thereby achieving cell compaction and its tightness.

 All case elements of the device (end plates and internal frames) are made of plastic. Unipolar and bipolar electrodes are made of graphite fabric material having a low electrical resistance.

 The device operates as follows. The source liquid enters the device, for example, through the pipe 12 for anolyte. Through the channels in the body of the terminal left plate and then through the holes in the inner gaskets, the liquid enters the internal anolyte cavity of the cell, where electroactivation occurs; Further, through the outlet openings in the inner gaskets, the liquid enters the channel from where it is directed into the anolyte cavity of the next cell, and so on. The anolyte is removed from the device through the pipe 14. In the same way, the initial liquid for catholyte enters the device through the pipe 13, moves as the anolyte through the cells through its channels and is removed from the device through the pipe 15.
