A brief description of the principle of electrostatic treatment of water

Qingda reminds you that there are five types of water that you should not drink.

1. Aging water:

Commonly known as "stagnant water", that is, water that has been stored for a long time. Drinking this kind of water often will significantly slow down cell metabolism and affect the growth and development of the body for minors; Middle-aged and elderly people will accelerate aging; The incidence of esophageal cancer and stomach cancer is increasing in many places, and according to the research of medical scientists, it may be related to long-term drinking of aging water. The data show that the toxic substances in aged water also increase with the increase of water storage time.

Second, a thousand boiling water:

A thousand boiling water is water that has been boiled on a stove overnight or for a long time, and water that has been boiled repeatedly in an electric water heater. This kind of water is boiled for too long, and the water has a high content of non-volatile substances, such as calcium, magnesium and other heavy metal components and nitrite. Drinking this water for a long time will interfere with people's gastrointestinal function, causing temporary diarrhea and bloating; Toxic nitrite can also cause hypoxia in the body, and in severe cases, coma, convulsions, and even death.

3. Steamer water:

Steamer water is leftover pot water such as steamed steamed buns, especially steamer water that has been used repeatedly and repeatedly, and the nitrite concentration is very high. Drinking this water, or boiling porridge with this water, can cause nitrite poisoning; Scale often enters the human body with water, and can also cause diseases of the digestive, nervous, urinary and hematopoietic systems, and even cause premature aging.

Fourth, do not boil water:

The tap water that people drink is chlorinated and sterilized. 13 kinds of harmful substances can be separated from chlorine-treated water, among which halogenated hydrocarbons and chloroform also have carcinogenic and teratogenic effects. When the water temperature reaches 90, the halogenated hydrocarbon content rises from 53 micrograms per kilogram to 177 micrograms, which is more than twice the national drinking water sanitation standard.

Experts point out that drinking unboiled water increases the likelihood of bladder cancer and rectal cancer21-38. When the water temperature reaches 100, these two harmful substances will be greatly reduced with the evaporation of the vapor, if you continue to boil for 3 minutes, it is safe to drink.

5. Re-boil water:

Some people are accustomed to boiling the remaining warm boiled water in the thermos before drinking, in order to save water, coal (gas) and time. But this "savings" are not enough. Because the water is boiled and burned, the water evaporates again, and the nitrite will rise, and if you drink this water often, the nitrite will accumulate in the body and cause poisoning.

I have never heard of electrostatic treatment of water, but I have heard of electrolysis of water with direct current to obtain weakly alkaline water, which is said to be beneficial to the human body.

The advertisement of the water should be a raw water cup, and the main function is to pour ordinary water and come out with weak alkaline water.

Analysis: 1. Basic principles.

The main principle of electrostatic water treatment technology is the formation of a high-voltage electrostatic field between the cathode and anode, and the treated water changes the dipole distance of water molecules and the amount of energy in the arrangement of other ions in the water through a specific electrostatic field, so that the morphology of scale molecules is temporarily changed, so as to prevent the adsorption of scale molecules on the wall of the device, to achieve the anti-scale effect, and through the high-voltage electrostatic field, the cell wall of aquatic organisms is ruptured, and the effect of inhibiting bacteria and killing algae is achieved to a certain extent.

Second, the technology is critical.

Electronic water treatment technology is to form a specific electronic field through microelectrolysis, so that the energy level of the hood in the water changes, causing the arrangement of scaling molecules to change, so that the ability of scale molecules to absorb on the wall of the device is reduced, so as to achieve the anti-scaling effect. The active oxidant substances produced by microelectrolysis kill bacteria and microorganisms in the water to achieve bacteriostatic and algae killing effects. Divine luck.

When the 220-volt 50Hz power supply is turned on, the controller of the electrostatic water processor supplies the energy of the auxiliary unit (energy releaser) to form a high-voltage electrostatic field between the cathode and anode. When the treated water passes through the energy releaser, the dipole moment of the water molecules increases and is arranged in a chain according to the positive and negative orientations. At the same time, some of the physical properties of water change (conductivity, dissolved oxygen, viscosity, surface tension, etc.). The water treated by this method is often referred to as electrostatically activated water.

The high-voltage electrostatic generator is one of the indispensable equipment in electrostatic powder coating. The reason why the powder is adsorbed on the surface of the workpiece is the result of the high-voltage static electricity generated by it.

There are two types of high-voltage electrostatic generators: tube type and transistor type. The tube type has reliable performance, stable output voltage, and can withstand overload. The transistor type is small in size and consumes less power. There are also electrostatic generators that combine the two, which concentrates the advantages of both.

The basic principle of all kinds of electrostatic generators is the same: by a stable DC power supply (composed of a step-down circuit, a rectifier filter circuit, a voltage stabilization circuit) to provide energy, through self-excited oscillation (generated by an oscillating coil or integrated circuit), it is converted into a frequency of 5kHz 20kHz, and boosted to 6kV 10kV alternating power, and then through multi-stage (generally 10 levels, there are also 12 levels) pressure rectification, you can obtain a 60kV 100kV high-voltage DC source - high-voltage electrostatic.

The technical principle of the high-voltage electrostatic circulating water processor: based on the technical principle that the equipment can exert high-frequency electric field force and electrostatic attraction to the water.

Mechanism of action of high-voltage electrostatic circulating water processor:

The high-frequency electric field force cracks the molecular structure of the associated water, distorts the salt scale crystal, and dissolves and removes the scale.

Electrostatic repulsion effect, dispersing effect, preventing salt binding and scale microcrystalline growth;

High-voltage static electricity changes the biological field of bacteria, causing them to lose their living conditions;

The electric field increases the potential of the water body to become a "sacrificial anode", so that the metal equipment at the "cathode" is protected from corrosion.

As a small flow rate, the water quality is mainly scaling type, and it is used under the condition of small concentration factor. Parameter Type Electronic Water Processor Electrostatic Water Processor Internal Magnetic Water Processor Water Temperature( )150 80 80 Flow Rate(m s) —Applicable Water Quality(mg L) Total hardness<550 Total hardness<7000 Total hardness<3000 Mainly suitable for scaling component is carbonate type water, when the water contains phosphate, it should be used with caution, the main scaling component in the water is phosphorus.

Salts and silicates should not be used.
