The invention discloses a water mist jet arc discharge nitrogen fixation device and a detection method. The device comprises an atomization unit, a liquid pump system, a discharge reaction area, a catalytic reaction area, a high-voltage alternating current power supply, a data acquisition and control unit, a discharge spectrum detection unit, a power supply parameter detection unit, a gas-liquid separation unit, a buffer unit, and liquid storage tanks A and B. According to the device, a gas-liquid two-phase discharge system is designed. Firstly, water forms water mist through an atomizing nozzle; a high-voltage power supply is used for driving to form arc discharge; active ingredients such as active oxygen and active nitrogen which are similar to thunderstorm weather and are beneficial tocrop growth are efficiently generated in water mist, and synergistic effect is achieved by means of cooperation of ultrasonic wave and a catalyst; by acquiring power supply parameter and discharge spectrum parameter data, physical parameters such as a gas-liquid two-phase water-gas mixing ratio and a power supply voltage are automatically regulated and controlled; and by using an optimal energy efficiency ratio tracking method, the device always works near an optimal energy efficiency ratio point in use, so that the yield of discharge active components and the working efficiency of the deviceare effectively improved.
Description
Technical field [0001] The invention relates to a water mist jet arc discharge nitrogen fixing device and a parameter detection and automatic control method, belonging to the technical field of high-voltage electrode discharge. Background technique [0002] The gas-liquid two-phase gliding arc discharge plasma technology is a new type of low-temperature plasma technology that integrates physical and chemical effects such as oxidation, acid, and ultraviolet radiation. The gas-liquid two-phase discharge plasma in water or in contact with water produces a large amount of active substances (also called active species) due to electron collision and ultraviolet radiation, such as HNO x , NO x , ·OH, H 2 O 2 , O 3 , ·O, etc., these active ingredients can be widely used in agricultural production, environmental protection, material processing, biomedicine and other fields. Gas-liquid two-phase arc discharge has the advantages of simple structure, convenient use and high energy efficiency...
