The water treatment ozone generator product differs from the air type in that it generally adopts a closed structure and has a high concentration of ozone. After the ozone occurs, the ozone is dissolved in water through a gas-water mixing device through the pipeline. Because of the ozone production conditions and component life requirements, it is generally necessary to pre-treat the air or use a high-concentration oxygen source. This is mainly because the ozone production is closely related to the dryness of the air, so most of them are equipped with a gas source drying system.

1. Water treatment ozone generation technology and supporting technology Water treatment ozone generation application technology is mainly divided into four major parts: occurrence, cooling, drying, gas-water mixing, and six major technologies of electronic control system and structural system.
The concentration unit of ozone used for water treatment is generally calculated in mg/L, which is a thousand times worse than the commonly used mg/m3 of air type. It can be seen that water treatment requires high concentration and large amount of ozone to be applied, and ozone generation occurs. The quantity/hour, load power consumption, air source dryness, product life and so on are the main indicators.
Water treatment ozone generation mostly uses air gap discharge method. Due to concentration demand, its power consumption is increased, and the temperature rise of the device is also inevitable. Temperature rise is the main factor affecting ozone generation and equipment life, so cooling is generally required, mainly air cooling. There are two kinds of water cooling, and some are solved by cold air source. Which method is adopted is determined by equipment design.
Under the same ozone generating components and power supply conditions, the ozone production is directly proportional to the dryness of the gas source. That is, the higher the dryness of the gas source, the higher the amount/hour value, so the purification and drying treatment of the gas source is not possible. Less, generally referred to as a gas source pretreatment or a gas source dryer system. At present, the means for drying the gas source mainly include freezing, dew condensation, chemical method, etc., and the dryness is calculated by the air temperature, for example, -40 ° C refers to the degree of drying of the gas source at -40 ° C.
Gas-water mixing device is an indispensable supporting technology for ozone treatment. Although ozone is easily soluble in water and its solubility is ten times higher than that of oxygen, it must use a technical means to make ozone and water fully contact, contact area and time. Ozone concentration, pressure, etc. are all determinants of mixing efficiency. At present, the main mixing of ozone and water is as follows:
Helium method: This is a traditional and simple method. It relies on ozone gas to compress and use some kind of foaming device to make ozone form bubbles and fully contact with water. It is easy to see that the smaller the bubble, the more the depth and the greater the depth. The better the effect.
The jet method: also known as the venturi method, is to use the water to flow through the pipe to increase the flow rate to form a vacuum suction, and the ozone and water are mixed in the pipeline. When installing this device, the first one must be matched with the pipeline (according to the pipe diameter), the other is that there should be no back pressure in the flow direction of the jet, to prevent water from entering the ozone generating tank, and third, the jet is extended. The pipeline must be above 2.5m, the longer the efficiency is, the fourth is that the flow rate should reach a certain amount to ensure the formation of negative suction. The fifth is that the device and the pipeline must be made of stainless steel or plastic to prevent the use of steel and iron to avoid ozone and oxidation. corrosion. The jet method is more efficient, but the installation design and requirements should be quite strict.

Freeze-dried powder is a sterile powder injection obtained by freezing the liquid medicine into a solid state in a sterile environment, and subliming and drying the water in a vacuum. Freeze-dried powder is composed of a bottle of high-purity and high-active biological protein freeze-dried powder and a high-purity liquid essence. When using, it needs to be connected with a patented vacuum to reconstitute the freeze-dried powder and the essence to activate the biological protein activity.
