First, the water of the magnetization technique

Use of magnetic field effects on water processing, known as the magnetic treatment of water. This method is circulating cooling water through magnetic fields, water cutting several times after the "magnetic" magnetized water "magnetized water" in the crystal formation of scale, but rather amorphous powder, so no glue on the wall or other surface that runs through the water and regular sewage to control its quality.

1.1 magnetization mechanism

(1) magnetization inhibition mechanism

Water flow through the magnetic water treatment plant, subject to Lorentz force, water is negative ions move in the opposite direction, a magnetic field generated potential difference between yin and Yang, the formation of micro-electronic flow, you can pipe wall original rust (Fe2O3) oxidation, generate a magnetic iron oxide (Fe3O4), magnetic iron oxide can be in a stable state, forming a layer of protective film, the iron wall and water completely separated, which played the role of the inhibitor.

(2) magnetic treatment anti-scaling mechanism

Use magnetization technique industrial cooling water anti-scale treatment, their mechanism of action is the magnetic field on water and water of the role of ion occurs, change the crystallization of fouling Crystal grain size, speed, crystal structure and magnetic field on the river system is very complex and at a variety of mutually reinforcing, and sometimes offset each other, the final State is a comprehensive variety of mechanisms.

(3) of the magnetization sterilization mechanism

Magnetic field effects on organisms is very complex issues, current research work is mainly concentrated in the biological effects of magnetic field and magnetic field of a chemical reaction and alternating magnetic field effects on the human body. Bacteria in the magnetic field can be viewed as 0.5 ~ 1m, length of 1 ~ 8m magnetic dipole, when its with the water flow through the gradient magnetic field, magnetic and induced current role. When the current reaches a certain threshold 8 ~ (10-3A/m2), cause the cells to destroy or alter the ion channels through the cell membrane so that protein denaturation or destroy the enzymatic activity. But the magnetic field sterilization mechanism of, bacterium biological effects and magnetic fields of relations and various bacteria on the magnetic field of the response, much remains to be done.

1.2 magnetization effect

Experimental results demonstrate that the magnetization can effectively reduce system corrosion rate, dirt deposition velocity and thermal resistance and the dirt has a bactericidal effect. But in practice, because of the different water quality conditions, some system has high adhesion rate, specific attention in the design and use.

2. electrostatic water treatment technology

Electrostatic water treatment method is also called high pressure electrostatic method. Its core is an electrostatic water processor (also called static scale controller, electrostatic water generator). In recent years, both at home and abroad is also another kind of electrostatic water processor a ion rods (Ion-Stick) electrostatic water processor. The ion stick is a new type of high-voltage electrostatic effect water processor. It has been applied to central air conditioner circulating cooling water, chilled water systems.

2.1 electrostatic water processor

Electrostatic water treatment technology and scale principle, that, in the role of strong electric field, the water molecules of the dipole moment increases, it and the cationic and anionic salts of hydration capacity is increased. The result is solubility increases the scale, accelerates the speed of the dissolved furring, thus have the scale and effect of dissolved dirt.

2.2 ion rods

In recent years, the country also has another electrostatic water processor-the ion stick (Ion-Stick) electrostatic water processor (ion rods). The ion stick is a new type of high-voltage electrostatic effect water processor. It applies to the central air conditioning circulation cycle cooling water, chilled water, heat and water supply systems.

Ion rods (large system can be used in series of multiple root) scale dissolve scale effect is clear, and easy installation, small size, easy maintenance, the service life of 10 years. Electrostatic water treatment technology features: both fouling and scaling, biocides, small size, the device is durable, and does not pollute the environment, management convenience. China has many examples of successful application, believe in the central air conditioner circulating water treatment engineering practices will be gradually introduced.

2.3 electronic scale and gauge

Electronic scale instrument is the use of electronic lines of high frequency electromagnetic oscillation, in fixed levels between certain intensity of high frequency electromagnetic field, circulating cooling water in the absorption of high frequency electromagnetic field energy, water molecules as dipole is constantly repeated polarization produced distortion, deformation, reversal, oscillations, the formation of active high single molecule or small associative groups State of water, thus increasing the water molecules between dipole moment, promote water fouling substance and its components, changes in circulating cooling water forms of sedimentary material and related ion of King early performance and water molecules and other ions combine State, CaCO3 precipitation of Crystal and other sediments and extend the time for small particles precipitated amorphous, ultimately prevent scale generation and loose Peel has generated scale.
