Description

Water ionization reactor

Field of technology

The technical solution relates to a water ionization reactor as part of water ionizers for continuous operation and easy repair.

State of the art

At present, water ionizers have a non-detachable reactor design due to its hermetic closure. If the ion membranes or electrodes become clogged with limescale, the entire reactor is replaced. During its operation, it is not possible to guarantee the stability of ionized water quality for a long time.

The essence of the invention

The above drawbacks are eliminated in the proposed easy-to-disassemble Water Ionization Reactor.

The task of the technical solution is to build a water ionization reactor composed of ionic membranes, made of textile materials or clay, and electrodes, made of titanium plates, mesh or grid, on the principle of sandwich arrangement to separate alkaline and acidic water, where each added titanium electrode is inserted with a rotation of 180 degrees compared to the previous one. The sandwich can be assembled and compressed into a single block using any fastening device, ie clamps, screws, etc. This design is easy to disassemble for repair. Spacer frames are placed between the ionic membranes and the electrodes, which regulate the distance between the electrodes and, thanks to their special shape, divide the water at the outlet into alkaline and acidic.

For a continuous ionization operation, cyclically switched paired solenoid valves and a change in the polarity of the operating electric current are used to avoid limescale deposition on the electrodes and the ion membrane.

For a continuous ionization operation, cyclically switched paired solenoid valves and a change in the polarity of the operating electric current are used to avoid limescale deposition on the electrodes and the ion membrane.

Calibrated outlet nozzles are used for the correct volume ratio at the alkaline and acidic water outlets.

The water ionization reactor comprises a water inlet to the reactor, at least two titanium electrodes for ionizing water, an electrically connected source of electrical energy and at least one ion membrane for ion separation, the ion membrane being located between the pair of titanium electrodes. Its essence is that behind the water inlet to the reactor there is a supply line, which is provided with a water flow sensor, and that two outlet lines are upstream of the reactor outlet. Each of these outlet pipes is branched into two branches, the first branch of the first pipe and the first branch of the second pipe being each equipped with one alkaline water outlet solenoid valve, the second branch of the first pipe and the second branch of the second pipe being each equipped with one acid water outlet solenoid valve. . Behind the acid water outlet solenoid valves, the branches passing through them are connected to an acid water outlet pipe, which is provided with a flow restrictor to control the ratio of alkaline to acid water volumes. The reactor also contains a microprocessor for controlling the switching cycle and setting the operating current, which is connected to the titanium electrodes, the source of electrical energy, with the output

Clarification of drawings

The water ionization reactor of the present invention will be described in more detail with reference to the accompanying drawings, in which: FIG. 1 shows the overall appearance of an exemplary water ionization reactor assembly. Fig. 2 is a block diagram of a water ionization reactor component.

Examples of embodiments of the invention

Each titanium electrode 1 consists of two spacer frames 9 and the electrode itself. The ionic membrane 2 is made of a textile material or clay.

When these ionic membranes 2 and the titanium electrodes 1 are placed in a sandwich arrangement with a regular rotation of the titanium electrodes 1 by 180 degrees, an ion reactor design is obtained in which the flow of basic and acidic water is separated at the outlet. This is achieved by drilling the jumper of the spacer frames at a specific location and installing a water flow sensor 5 and acid water outlet solenoid valves 3 and alkaline water outlet solenoid valves 4, which are structurally the same.

Water enters the water ionization reactor via the water flow sensor 5 and the data obtained from the water flow sensor 5 are evaluated in the microprocessor 6. Depending on the required water pH output value and flow rate, the PWM (Pulse Width Modulation) is set to titanium electrodes 1 of the water ionization reactor or the operating voltage of the titanium electrodes 1 for water ionization. The power supply 7 is always direct current.

To prevent the formation of limescale on the titanium electrodes, the microprocessor 6 changes the polarity of the voltage during each cycle, i. the anode becomes the cathode and vice versa - cycles 1 and 2, and switches the output solenoid valves 3 of the acid water and the outlet solenoid valves 4 of the alkaline water in pairs so that the set pH value of the water always reaches the output.

These cycles can vary according to the hourly interval or according to the specific workflow. To adjust the volume ratio at the alkaline and acidic water outlets, whereby the acidic water should have three times less volume than the alkaline water for some tasks, a flow restrictor nozzle 8 is placed at the acidic water outlet. This nozzle regulates the volume ratio of water at the outlets.

Industrial applicability

The technical solution according to the proposed model will find application in all areas where it is necessary to build industrial water ionizers with continuous operation and minimal maintenance costs.
