At present, the common ozone generators in swimming pool equipment can be divided into the following three categories according to the common raw materials for ozone production:
1. Gas legal ozone:
Of course, the air filters dry ozone generator with low concentration ozone gas. The ozone concentration prepared by this method is generally 20mg/l-30mg/l. Not only the gas consumption is large, but also the power consumption is high.
2. CO2 legal ozone can be divided into two types:
1. Prepare ozone with sufficient oxygen: of course, drying - oxygen separation - high concentration ozone generator - ozonation of CO2. This kind of method has been developed to use high-voltage power supply and carbon molecular sieve pressure swing adsorption medical oxygen generator (that is, to absorb nitrogen in the gas and increase the oxygen content in the gas to 85% - 95%). Ensure that the prepared ozone concentration exceeds 80mg/l, the ozone production can be adjusted, and the whole process is controlled by microcomputer
Cpu synchronization control. The new generation of CO2 ozone generator that can automatically shut down any abnormal change found at any stage to ensure safe operation is suitable for the disinfection and sterilization of swimming pool water and the preparation of ozone by air pressure method. The cost of ozone preparation is much less than that of oxygen preparation.
This kind of air pressure ozone preparation machine and equipment, the ozone generator works stably, and uses medium and high voltage power supply to improve the safety factor and credibility of the ozone generator, thus preventing the risk of fire accidents due to the high charging and discharging working voltage of the DC switching power supply. In addition, at the operation level, PLC is the key to operation, which has the function of remote control, can maintain the linkage with circulating pump and booster pump, and has various interlocking functions such as over-current protection, cooling circulating water over temperature protection, transformer over temperature protection, and server cabinet start maintenance. It is a relatively new ozone preparation process. The machine and equipment are currently manufactured in China and have been widely used to disinfect the water in swimming pools.
2. Preparation of ozone from oxygen:
Liquid oxygen high concentration ozone generator ozonation of co2. The ozone concentration prepared by this method can exceed 80mg/l, but there must be a liquid oxygen bottle warehouse on the spot. Although the price of liquid oxygen is high, the use of liquid oxygen is small. But the discomfort is sterilized by ozone in the natatorium.
3. Ozone ultraviolet light combined ozone generator generator set.
In the same machine and equipment, there are ozone and ultraviolet ultrasonic generators, which can have two-way effects. That is, not only can the pool water and ozone be fully mixed, but also can be oxidized, disinfected and sterilized in the touch room. Before the water flows out of the touch room, it can be converted into oxygen according to the catalytic oxidation effect of ultraviolet light, so as to remove ozone. And touch the unnecessary ozone in the room.
The rear seats are dissolved into air by waste gas. In the software of pool water disinfection and sterilization system, there is no need to set activated carbon filtering device to remove the remaining ozone in the disinfected solution, which has a great coordination ability and saves the total area of the main machine room and capital construction costs.
