Description

The technical solution relates to a device for the electrotechnical industry, an original rotary electrode for electrolysis, vertically embedded in an electrolyte, with a mechanism for continuous wiping of deposits arising during electrolysis. The technical solution belongs to the field of innovation of electrolytic devices in electrochemical industry and environmentalism.

BACKGROUND OF THE INVENTION

Electrolytic devices are known from the knowledge that electrolytes are capable of conducting electrical current (Faraday 1831) by immersing two electrodes at a certain distance into the electrolyte, and electrolysis is carried out by connecting them to direct current with known effects and devices designed for this purpose. :

• Equipment for the production of pure metals (electrometallurgy - aluminum) • Equipment for the electronic cleaning of metals - refining (copper, zinc, nickel) • Equipment for covering objects with a metal layer (plating - chromium, nickel, gold plating) • Equipment for producing metal castings (for the production of casting molds - galvanoplasty) • Galvanic etching device - the metal electrode is in some places covered with an electrically non-conductive layer, the uncovered part is electrolytically etched by current passage • Accumulators - chemical sources of electric charge, electrodes pass through when charging.

• Tnbology - metal coating • Device for determining the chemical composition of a substance by changes in the electric current passing through the solution of the test substance (polarography) • Particle separation of various chemicals (water electrolysis) • Hygienization of water reservoirs by electrolysis

Nowadays, electrolytic devices that use deposits on electrodes, such as tribology, electroplating, etc., are most commonly used. Electrolytic devices are also used where a weight loss of one of the electrodes is required as in galvanic etching.

In many cases, however, deposition on the electrodes is undesirable because it affects the transient resistances and hence the currents and, in part, the current density in the electrolyte when connected to a direct current source, i.e. values that affect the desired state or resp. the electrolyte composition thereby distorting the measured values or the desired electrolysis effect. Various solvents are used to remove deposits (pH, conductivity, etc.), but the process is discontinuous and does not address this undesirable effect directly by the design of the device.

In addition to measuring electrodes for water electrolysis and electrolytic water hygiene in a continuous process, where electrolyte flows are often high and deposits reduce the efficiency of the process, the requirement to eliminate deposits on the electrodes is required as much as possible.

Some patented solutions for electrolytic devices are known, but they do not solve the mechanical regeneration of electrodes such as:

IPO SR patent no. 282 797

Electrolytic water treatment plant with rotating electrodes. Electrodes rotate horizontally, do not solve electrode regeneration (December 3, 2002).

IPO SR patent no. 288 407

Method of disposal of cyanobacteria in stagnant waters and equipment for its implementation (16 March 2012). The device uses multi-stage electrodes, the bottom electrode rotates horizontally, does not solve electrode deposit regeneration.

WO 9010097

The purification electrolytic device has an integral cylindrical anode and the coiled wire as a cathode, by electric current and oxidation acts to destroy bacteria and algae in the water. It does not solve electrode recovery.

US 2002078990

A floating disinfectant device uses a larger number of electrodes. To achieve a nearly maintenance-free sanitation process, the reverse polarity module alternates the direction of current at a predetermined time interval. Reversing polarity reduces scale buildup and prevents corrosion of metal electrodes. Reverse polarity of the current is only partially effective and not for every electrolyte.

US 2005067300

The device is used for disinfection or disinfection. sterilization of contaminated water reservoirs (also from water and other outdoor sources). The closed body allows the electrolytic device to float or be placed in a water reservoir. Preferably, it is possible to use a pump which pumps water through an electrolyzer containing halide ions, such as chlorine ions. The device does not solve the regeneration of electrodes, which is necessary for halogen elements in water.

US 6508929

The device is designed for the production of highly concentrated brine. Metal probes - electrodes are removable, placed in a case, their replacement is solved by their regeneration.

The essence of the technical solution

These drawbacks are overcome by a technical solution based on the construction of a rotating electrolytic electrode with a scraping deposit, consisting of non-conductive load-bearing prisms, preferably of hardwood, which support the hinged rotary plate electrodes vertically positioned to the water level, also of another electrolyte. The electrodes are submerged in the electrolyte under the electrode axis. On the top of the electrodes is a non-immersed part of the electrodes, there is a scraping device mounted on a mechanical principle with catching of the removed deposit in the collecting vessel. water jet blasting equipment, whether or not with mechanical free-falling blasting filler on the bottom of the electrolyte tank. The ring electrodes are arranged in pairs for the positive and negative poles of the electric current, the number of pairs being at least one. By rotating the electrodes, the cleaned surfaces are immersed in the electrolyte thereby ensuring a low and constant transient resistance at the interface of the electrode material and the electrolyte and hence the stability of the electrolysis process.
