4、 Product function description:

gd55光大彩票1. The circulating water cooling treatment system is a system for cooling and water quality treatment of the circulating cooling water in the industrial sector. The circulating cooling water is called In the process of cooling production equipment or products, the water temperature of circulating water and cooling water rises. Although their physical properties have little change, after long-term recycling use, some dissolved substances in the water concentrate or disappear, dust accumulates and microorganisms grow, which causes the deposition of scale in the equipment and pipes or corrosion of metal equipment and pipes. Therefore, it is necessary to cool and stabilize them in order to make circulation The water system works normally.The circulating water system is generally composed of the following parts:

① Heat exchanger in production;

② Cooling structures;

③ Circulating water pump and sump. The cooling structure of cooling water cooling treatment usually uses cooling pool or cooling tower; the production of circulating cooling water in the industrial production process needs to make raw materials react to generate the required products, usually heating raw materials; at the same time, the production products need to form industrial products, and often need to be cooled; therefore, in the industrial production process, a large amount of cooling water is often needed, the total amount of industrial cooling water It can account for more than 60% of the total industrial water consumption.

2. Principle of sterilization and algaecide:

The circulating water treatment unit is used to purify the water quality of microorganisms (such as bacteria and algae) breeding. Its principle is that when the water flows through the scll type water treatment unit, the ecological environment of bacteria and algae in the water changes and the living conditions are lost and die. There are three aspects

① Any kind of creature has its own specific living biological field. The distribution and movement of electric charge in organism is affected by the change of electric field in the environment outside the organism, thus affecting the life activities of organism. The microorganisms on the earth can only adapt to and live in the electric field intensity (130v / M) on the earth's surface. Changing the electric field intensity can change or affect the physiological metabolism of bacteria (E.coli), such as gene expression program, enzyme activity, etc., which makes the survival of bacteria abnormal, which is one of the reasons leading to bacterial death.

gd55光大彩票② There are many channels in the cell membrane. Through these channels, the cell connects with its surroundings. These channels are composed of a single molecule or a molecular complex that allows ions to pass through. The regulation of ion channels affects cell life and function. The external electric field destroys the ion channels on the cell membrane and changes the internal current regulating the cell function, thus affecting the life of bacteria. The bacteria containing liquid flows through a strong electric field, which causes the instantaneous changing current to pass through the liquid, and the cells in the conductive path are killed by the high-speed electronic shock wave, so as to achieve the goal of sterilization.

③ During the treatment of water by electric field, the dissolved oxygen is activated to produce O2 -, · Oh, H2O2 and 1O2 (O2 - is superoxide anion radical, · Oh is radical radical, H2O2 is hydrogen peroxide, 1O2 is singlet oxygen). Active oxygen radicals can produce a series of harmful effects on microbial collective, which is the main reason for aging of organism. O2 - can damage important biological macromolecules and cause microbial organism damage; O2 - donates microbial organism membrane peroxidation and accelerates aging.

3. Anti corrosion working principle:

gd55光大彩票① Active oxygen forms oxide coating on the new tube wall.

gd55光大彩票② Microbial corrosion and silent corrosion were inhibited.

gd55光大彩票4. Scale prevention and descaling principle:

After water passes through SCLL processor, the polymerization degree of water molecules decreases, the structure deforms, and a series of small elastic changes of physical and chemical properties occur, such as: the water dipole moment increases, the polarity increases, thus increasing the water and capacity and scale solubility of water.Salt ions in water, such as Ca2+ and Mg2+, are subjected to the action of electric field and gravitation, so their arrangement changes and they are difficult to accumulate towards the pipe wall, so as to prevent scale formation.Under the action of electric field and gravity, the arrangement of Mg2+ changes, and it is difficult to accumulate towards the pipe wall, so as to prevent scale formation.Specific energy fields change the crystallization process of CaCO3, inhibit the generation of calcite, and provide energy for the generation of crystal.After treatment, the surface Zeta potential of suspended particles and colloids in water changed, and flocculation tended to precipitate.The sediment is washed away or removed by the current to purify the water.Reactive oxygen species are produced in the treated water.The process of reactive oxygen mixture crystallization can accelerate the colloidal instability.For the scale system, reactive oxygen species will destroy the electron binding force between scale molecules, change its crystal structure, and change the hard old scale into loose and soft scale. In this way, the scale will gradually flake off, even into fragments and debris will fall off, so as to achieve the purpose of scale removal. 　

gd55光大彩票5. matters needing attention:

main problems in circulating water operation:

(1) Scale:

Due to the continuous evaporation of circulating water in the cooling process, the salt concentration in the water increases continuously, which exceeds the solubility of some salts and precipitates. Common scales include calcium carbonate, calcium phosphate, magnesium silicate, etc. The texture of scale is relatively compact, greatly reducing the heat transfer efficiency, and the scale thickness is 0.6mm

The heat transfer coefficient is reduced by 20%. 　　

(2) Dirt:

Dirt is mainly composed of organic matters, microbial colonies and secretions, sediment and dust in the water. The soft texture of the scale not only reduces the heat transfer efficiency, but also causes corrosion under the scale and shortens the service life of the equipment. 　　

(3) Corrosion:

Circulating water corrosion of heat exchange equipment, mainly is the electrochemical corrosion, the causes of equipment manufacturing defects, enough oxygen in water, the water corrosive ions (Cl -, Fe2 +, Cu2 +) and microbes secrete mucus generated by the factors such as dirt, corrosion of the consequence is very serious, uncontrolled a very short time even heat exchanger, water pipe road equipment scrap.　　

gd55光大彩票(4) Microbial slime:

Because the circulating water is dissolved with sufficient oxygen, proper temperature and rich nutrition conditions, it is very suitable for the growth and propagation of microorganisms. If not controlled in time, the water quality will quickly deteriorate, stink and turn black, a large number of slime deposits and even blocks in the cooling tower, the cooling and heat dissipation effect will be greatly reduced, and the equipment will be corrodedAggravation. Therefore, the reproduction of microorganism must be controlled in the treatment of circulating water.

Circulating water treatment equipment is widely used in metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electric power, urban water supply. Such as industrial wastewater, circulating water filtration, emulsion regeneration, waste oil filtration, continuous casting water system, blast furnace water system, high pressure water descaling system for hot rolling, etc.
