Embodiment Construction

[0031] Below in conjunction with accompanying drawing, describe preferred embodiment of the present invention in detail:

[0032] figure 1 According to one embodiment of the present invention, it is a system diagram of water treatment using an atmospheric pressure liquid film bubble discharge plasma reaction device.

[0033] Such as figure 1 As shown, the solution in the 101 liquid pool is pumped out by the 102 two-way quantitative hydraulic pump at a certain flow rate, and enters the 103 liquid film type bubble discharge plasma reaction device, and the working gas in the 106 gas cylinder enters the 103 normal pressure liquid film type reaction device through the 105 flow meter. The bubble discharge plasma reaction device is used to form bubbles. Under the action of a high-voltage power supply with a frequency of 104 5kHz-100kHz and a voltage of 1kV-30kV, bubble discharge occurs to generate plasma, which purifies the solution to be treated. The solution finally flows back in...

Abstract

An atmospheric pressure liquid membrane type bubble discharge plasma reaction device belongs to the technical field of low temperature plasma application and can be applied to water treatment. The atmospheric pressure liquid membrane type bubble discharge plasma reaction device is characterized by comprising a metal power electrode, an insulating medium layer matched with the insulating medium layer and an insulating container. The surface of the insulating container is communicated with a liquid inlet, a liquid outlet and a gas inlet, liquid to be treated forms a liquid membrane on the surface of the insulating medium layer (one side of the insulating medium layer is not adjacent to the metal power electrode), and working gas enters a gap between the metal power electrode and the insulating medium layer and enters the liquid membrane through holes distributed all over the surface of the insulating medium layer to form a large amount of bubbles. Under the effect of a high-voltage power supply, gas-liquid two-phase mixed discharge is generated by the bubbles and local scope surrounding the bubbles, and generated plasmas are used for purifying the liquid to be treated. The atmospheric pressure liquid membrane type bubble discharge plasma reaction device has the advantages of being high in utilization rate of effective components, large in action length and wide in action surface, and reducing requirements for plasma excitation sources.

Description

technical field [0001] The invention belongs to the application technical field of low-temperature plasma, and relates to an atmospheric pressure plasma discharge reaction device which can be used for water treatment. Background technique [0002] Due to the complex composition and variety of pollutants in sewage, especially industrial wastewater, some organic substances in it are difficult to be effectively degraded when treated by conventional methods; even if some can be degraded, there will be problems such as incomplete degradation and decolorization, and long time-consuming degradation. . Therefore, it is of great significance to develop new and effective sewage treatment methods. Among the new sewage treatment technologies, plasma water treatment technology has attracted widespread attention due to its outstanding characteristics such as good degradation effect, high treatment efficiency, and strong environmental compatibility, and has shown a good application prospe...
