Micro and nano bubble generator for agricultural irrigation
The micro/nano bubble generation technology utilizes a micro/nano bubble generation device to rapidly and efficiently dissolve gas into water to generate supersaturated micro/nano bubble water. The prominent characteristics of micro and nano bubbles are their slow rise in water, long residence time, and self compression. They have high solubility in water. Moreover, micro and nano bubbles have physiological activities to promote plant growth, improve plant growth rate, enhance root activity, and promote root growth and development.
The technical principle of the nutrient solution micro/nano bubble oxygenation disinfection system: using micro/nano bubble generation technology to dissolve pure oxygen into the nutrient solution to form supersaturated micro/nano bubble water to oxygenate the nutrient solution; Using micro/nano bubble generation technology, pure oxygen and ozone are dissolved into the nutrient solution to form micro/nano bubble ozone water, which simultaneously plays a dual role in disinfection and oxygenation of the nutrient solution. The nutrient solution micro/nano bubble oxygenation disinfection system directly oxygenates and disinfects the nutrient solution. Using micro/nano bubble technology to increase oxygen, the resulting micro/nano bubble has a slow release effect, which can ensure the dissolved oxygen concentration at the end of the planting groove.
Innovative points of micro and nano bubble oxygenation disinfection irrigation:
·Using micro/nano bubble generation technology to effectively dissolve oxygen and ozone in water, the generated micro/nano bubbles have a slow release effect, which can extend the retention time of oxygen and ozone in water and improve utilization efficiency;
·Ozone cooperates with ultraviolet sterilization. The reaction between ozone and organic molecules requires activation energy. Ultraviolet irradiation increases the energy of organic molecules, increasing the proportion of activated molecules, and making it easier for organic compounds to decompose under the oxidation of ozone. In addition, dissolved ozone in water can generate hydroxyl radicals (OH -) with higher reactivity under ultraviolet irradiation, thereby accelerating the removal rate of organic substances in water;
·Filtering the nutrient solution before ozone and ultraviolet disinfection reduces the impact of reducing substances and opaque impurities in the nutrient solution on the disinfection effect, and improves the sterilization effect;
·During soilless cultivation and crop rotation, the nutrient solution containing high concentration of micro and nano bubble ozone water is circulated several times in a series of hydroponic facilities, effectively removing pathogenic bacteria from the dead corners of the facilities;
·It can achieve dual functions of oxygenation and disinfection, which can both oxygenate and disinfect nutrient solutions, effectively reducing the cumulative investment cost of a single device;
·The device adopts automatic control and independently developed CPU integrated controller, which is easy to operate; The control unit reserves a data port that can be connected to the control units of other devices to achieve integrated control of the Internet of Things.
