Embodiment Construction

[0034] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0035]The object of the present invention is to provide an air plasma jet water treatment experimental research device with stirring function. The kinetic process of the wastewater treatment reaction is: the water to be treated is rapidly stirred by the agitator, resulting in an exponential increase in the contact area between the wastewater solution and the air from the plasma area, and effectively improving the activity of the discharge during the discharge reaction process. The collision frequency of particles (high-energy electrons, active free radicals, ultraviolet rays, and ozone) with toxic species in water (organic pollution, heavy metal ions, germs, etc.). Thus, the chemical reaction rate is effectively increased. The rotational speed of the agitator of the present invention is adjustable, and can adjust the flow rate of the sol...

Abstract

The invention discloses an air plasma jet water treatment experiment research device. The air plasma jet water treatment experiment research device is characterized by comprising a reactor, a plasma jet generation device and a stirring device, wherein the reactor is used for containing waste water; the plasma jet generation device is used for generating air plasma jet and discharging the air plasma jet in the waste water in the reactor; the stirring device is used for stirring the waste water in the reactor. According to the air plasma jet water treatment experiment research device with a stirring function, stable and high-concentration plasma active particles can be generated, and the efficient plasma utilization and the full chemical action during water treatment are realized. The air plasma jet water treatment experiment research device is high in controllability and good in treatment effect.

Description

technical field [0001] The invention relates to a water treatment device, in particular to an air plasma jet water treatment experimental research device with a stirring function. Background technique [0002] Plasma is a macroscopic system composed of a large number of interacting charged particles that are still in an unbound state. It is the fourth state of matter at the same level as solids, liquids, and gases. The air plasma jet source (APJ) can be discharged in water to obtain low-temperature plasma, and the temperature of electrons in the low-temperature plasma is at 10 4 Above K, the temperature of ions and neutral particles is slightly higher than normal temperature, and the discharge process is accompanied by high-energy electrons, ultraviolet rays, shock waves, active particles (such as · OH, · O, · H, O 3 、H 2 o 2 etc.), this feature can be used to remove toxic species such as refractory organic matter, bacteria, and heavy metals in water. The low-temperature...
