Nikuni gas-liquid mixing pump is used to produce ozone water
Publish Time: 2024-08-01
Ozone has a strong oxidizing ability. It can decompose organic pollutants, kill bacteria and toxic substances, and decompose various dirty gases. Ozone oxidizes after several hours of use, and there is no secondary pollution left by other bactericides (such as chlorine dioxide). Therefore, it is widely used as a pollution-free clean treatment source for sterilization, deodorization, decolorization and other purposes. The application of ozone is divided into gas phase and liquid phase.
In the liquid phase application of ozone, the more traditional and widely used process is ozone generator + pressure pump + ejector + oxidation contact tower; in addition, there is a process of mixing ozone directly in the pump, namely the Nikuni gas-liquid mixing pump process. The following is a brief introduction to the characteristics of the Nikuni gas-liquid mixing pump and the performance comparison with the traditional mixing process.Application of Nikuni pump in ozone water preparationNikuni gas-liquid mixing pump is a model of the exquisite combination of Nikuni industrial pump design technology and precision machining technology. Its original design and excellent performance provide a more efficient and more ideal choice for ozone water treatment technology.1. Features of Nikuni gas-liquid mixing pump:
◎ High dissolution efficiencyAs shown in the figure on the right, the impeller of the Nikuni gas-liquid mixing pump has dozens of radially arranged blades on the periphery. The impeller generates friction and thrust during the rotation in the pump. The gas-liquid mixture sucked into the pump by negative pressure is vortexed and pressurized between each blade. The ozone has been evenly mixed dozens of times from the inlet to the outlet of the pump, so it can be fully dissolved in the water.◎ Long-term stable performanceThe Nikuni pump has a simple structure. Except for the mechanical seal, there are no metal friction parts in the pump. In addition, the pump is made of 304 or 316 stainless steel, and the sealing material is high-quality silicon carbide and polytetrafluoroethylene, which has excellent corrosion resistance.In addition, the low cavitation margin design of the Nikuni pump ensures smooth gas suction and mixing, and the performance is stable and reliable for a long time.◎ Small size saves installation spaceThe Nikuni pump has a reasonable structure and small size. Even in the equipment for producing 50 cubic meters of ozone water, the floor space of the Nikuni gas-liquid mixing device does not exceed 1 square meter, and the height of the device can be designed to be about 1-1.5 meters. It is especially suitable for the transformation of existing equipment and the equipment setting in existing plants.◎Easy to operate and maintainThe device structure of the Nikuni gas-liquid mixing pump is simple. After properly adjusting the water volume, ozone generation volume, oxygen volume and operating pressure, it can operate almost trouble-free for a long time and basically does not require maintenance.2. Application effect of the Nikuni gas-liquid mixing pumpAccording to the conditions such as the output and generation concentration of the ozone generator, the water volume, the amount of oxygen inhaled and the water temperature, the dissolution efficiency of ozone in water can be as high as 99% or more after using the Nikuni pump. Please refer to our company's application test report.
◎Low operating costs (electricity bills), users can get more benefits.◎Suitable for the production of high-concentration ozone waterIn industries such as sewage treatment and semiconductor cleaning that require the production of high-concentration ozone water, traditional processes require repeated mixing and extended contact time to achieve the purpose. As a result, the large-volume ozone generator and large oxidation contact tower increase the cost of the entire treatment equipment, the equipment footprint becomes quite large, and the treatment effect is not ideal. The mixing process using the Nikuni gas-liquid mixing pump can achieve a relatively ideal treatment effect while improving the mixing effect and shortening the mixing time.3.LimitationsThe gas-water mixing ratio of the Nikuni gas-liquid mixing pump is 1:9, that is, 10% of the water pump flow is gas and 90% is liquid. Therefore, it is generally only suitable for the production of ozone water using a pure oxygen source. This limits the application of the Nikuni pump in the production of ozone water equipment using a dry air source to some extent.However, given that the oxygen purity of the dry air oxygen source is about 21%, and the remaining 79% is inevitably converted into residual nitrides, it is not suitable for pure drinking water (pure oxygen sources are generally used to produce ozone water abroad). Furthermore, since the oxygen purity of dry air oxygen source is more than three times lower than that of pure oxygen source, the amount of ozone generator required to produce the same amount of water will increase accordingly, thereby increasing the investment and operation cost of the ozone generator.4. Application fields of Nikuni gas-liquid mixing pump
Nikuni pumps have won the praise of a large number of ozone users in Japan due to their high-efficiency mixing characteristics, and have already gained an absolute share in the Japanese market. Almost all small and medium-sized ozone tax production equipment uses Nikuni pumps. In recent years, especially in the application field that requires high-concentration ozone water, especially the chip cleaning use in the microelectronics industry requires a concentration of nearly 200ppm, the traditional mixing method cannot correspond to it at all, and it is Nikuni pumps (PTFE coated products) that are the best choice.Since its sale in China, tens of thousands of users (including equipment manufacturers and engineering companies) have adopted Nikuni gas-liquid mixing pumps, and a considerable number of users use Nikuni pumps for the transformation of existing equipment or the conversion of traditional equipment to Nikuni pumps because they do not meet the quarantine standards. So far, the renovation rate is zero.5. Supply rangeNikuni pump supply range is 0.5-100M3/Hr. Single pump or complete set of equipment can be supplied.Although the price of Nikuni pump is higher, in order to promote the development of ozone industry, our company can supply it to network members at a preferential price.
