Method of producing hydroxy free radical from reaction of ozone and exutad water

[0075] Oxygen gas 17 through figure 1 After the valve 1 and flowmeter 2 in the plasma generator 3, it is processed into O 3 , its concentration is as high as 400g/m 3. o 3 Through the control of the electric valve 11 and the check valve 12, it reaches the Venturi ejector or the vortex impeller pump 9 . The pressure difference produced by the water 19 drawn in by the pump 8 at the front and rear ends of the Venturi ejector or the vortex impeller pump 9 is 0.4MPa to make the water in an excited state, which is different from O 3 The plasma chemical reaction is carried out, and then further dissolved by the gas-liquid dissolver 10 to generate a hydroxyl solution 20 with a specific concentration of 2-10 mg/L. The undissolved ozone is separated and removed with a gas-liquid separator 11 and a residual ozone processor 16 . figure 1 The high-frequency and high-voltage power supply composed of the middle transformer 5 , the inverter 6 and the controller 7 can convert the power frequency 220V voltage 18 into high-frequency and high-voltage power for supplying power to the plasma generator 3 . The ozone concentration tester 4 is used to detect the ozone concentration produced, the hydroxyl solution concentration analyzer 14 is used to detect the concentration of hydroxyl radicals, and the pressure gauge 15 is used to detect the pressure of gas or liquid.
