The invention discloses a low-temperature
plasma activated water preparation device and method, and relates to the technical field of
plasma activated water preparation, and the low-temperature
plasma activated water preparation device comprises a transparent
liquid storage tank which is provided with a first liquid inlet, a first liquid outlet and a gas outlet; the preparation unit comprises a combination sheet, a second
electrode sheet and a rectangular cylindrical insulating transparent
enclosure wall, the combination sheet sequentially comprises a first
dielectric sheet, a first
electrode sheet and a second
dielectric sheet from top to bottom, and a first cavity is formed among the first
dielectric sheet, the first
electrode sheet and the second dielectric sheet and is communicated through a connecting
pipe and the like. And a cooling unit including a radiator, a water pump, a heat absorption water tank and the like can be arranged. According to the method, liquid is injected into the
liquid storage tank, after the gas injection unit injects gas into the first cavity, the
alternating current power supply is turned on, plasma is formed by ionizing air, and direct and indirect activation of the liquid is achieved. The device and the method can improve the activation efficiency and increase the concentration of active substances, and the cooling unit can stabilize the
ionization work and reduce the loss of
active components, and have significant advantages.
