Embodiment Construction

[0020] Below in conjunction with accompanying drawing and embodiment the utility model is further described.

[0021] Use a single optical fiber to confine the discharge gas to realize micro-plasma generation in liquid under atmospheric pressure. The device is as follows figure 1 As shown, a microporous optical fiber 1 is used to insert a high-voltage electrode 2. One end of the microporous optical fiber 1 is inserted and communicated with the air cavity 3, and the other end together with the high-voltage electrode 2 in it is inserted into the liquid to be treated. The sample 6 is below the liquid surface and suspended above the ground electrode 7 in the liquid. The high-voltage electrode 2 is connected to an AC sine wave high-voltage power supply 5 for generating plasma, the peak-to-peak voltage of which is above 14KV, and the frequency is within the range of 5KHZ-15KHZ. Before discharge, the discharge gas is passed through the gas mass flow controller from the gas inlet 4 i...

Abstract

The invention relates to a processing technology and device of an optical fiber plasma liquid. According to the invention, optical fiber pipes are utilized and uniformly ranked, and gas is introduced in the optical fiber pipes; a plasma is generated at a micropore optical fiber pipe orifice or end head by utilizing atmospheric pressure discharge; the area of the plasma is micro-controllable, the contact area of the plasma and a processing material is good, a processing effect can be obviously improved, and the energy utilization rate is greatly improved; and discharge gas is restricted by using optical fiber so as to generate a micro-plasma in a liquid at the atmospheric pressure to process a polluted liquid sample. The processing technology and device have the following specific advantages that gas utilization rate is high, discharge manner is simple, complicated vacuum equipment is not required, equipment cost is low, fungicidal efficiency is high, and energy consumption is low.

Description

technical field [0001] The invention relates to a plasma liquid processing device and a process, in particular to an optical fiber micro plasma liquid processing device and a process. technical background [0002] With the development of social economy and urbanization, the shortage of water resources and the pollution of water environment have become global problems in this century and are becoming more and more serious. Correctly mastering and rationally utilizing existing water treatment technologies and researching new water treatment technologies are important ways to solve water environmental pollution and rationally utilize water resources. [0003] my country's water treatment technology is in urgent need, but its development is slow and relatively backward, especially the lack of advanced treatment technology. The current conventional treatment combination of "coagulation + sedimentation + filtration + disinfection" cannot meet the requirements for the removal of C...
