Ozone decolorization experimental device

Ozone is a strong oxidant. Its oxidation ability is second only to fluorine in natural elements. Ozone can be used in water treatment for deodorization, sterilization, decolorization, iron removal, cyanide, and organic matter. This device is a demonstration experiment that uses ozone off -color discoloration. Through the hope of this experiment, the following goals are achieved:

1. By regulating different concentrations of ozone to determine its reaction time and effect.

2. Understand the oxygen decolorization through the direct observation of organic glass.

Second, the working principle of experimental device:

Ozone has a significant effect on discoloration, sterilization, and deodorization. The columns such as phenols and ozone react, and they are first oxidized into phthalate, and then phenylphenols continue to oxidize into neighboring. If there is enough ozone during the processing process, the oxidation reaction continues. In the reaction, only a small amount of phenol can be completely oxidized to carbon dioxide and water. This experimental device is only performed by ozone discoloration experiments. Ozone is gradually absorbed and decomposed as an oxidant as an oxidant. Placing polylene pheed balls in the reaction column can increase the contact area of ​​the ozone and achieve a better discoloration effect.

3. M--n technical indicators and parameters:

1. Environmental temperature: 5 ℃ ～ 40 ℃

2. Handling water 100 L/h;

3. Ozone can remove impurities in the water: dehumidifying sterilization, decocent, iron removal, oxide, and organic impurities.

Note: There is no color from the water, the turbidity improves

4. Dimensions of reaction columns: 柱80mm × 1300mm (2),

5. Total size of the device: 1100mm × 400mm × 1600mm,

6. Work power: AC220V ± 10%, 50Hz, single -phase three -line system, 500W power, safety protection: ground protection, leakage protection, overcurrent protection

In recent years, with the widespread application of CNC technology, the school has p--d more and more attention to practical and skillful talents that cultivate jobs in production and technical services. Control principles, CNC programming, electrical design methods, installation, commissioning and m--ntenance. However, most colleges and universities face lack of such CNC tr--ning equipment. To this end, the company has developed the principles of the electronic control system of CNC cars and the internship device for debugging and rep--ring the m--ntenance experimental desk. The use of this device can enable students to master many experimental content such as CNC's lathe system control principles, electrical design methods, selection of components, lathe electrical installation and debugging, fault diagnosis and m--ntenance, parts programming, and graphic simulation processing process to achieve the industrial production site Internship effect. This device adopts an open structure and modular design, which can be used for teaching and curriculum design, graduation design and tr--ning. *Limit and meet market demand. This device can also help scientific research and technical personnel to further understand the structure of CNC lathe, and also provides necessary conditions for technical personnel to carry out secondary development of CNC lathe systems. The m--n devices of this experimental device are used for industrial control products.
