Room temperature plasma torch array device for simultaneous fiber modification and sewage treatment

Abstract

The invention discloses a room temperature plasma torch array device for simultaneously modifying fiber filaments and treating sewage. Multiple rows of quartz tubes with built-in tubular metal electrodes are inserted into the conductive sewage solution electrodes. One end of the quartz tubes passes through the bottom of the plexiglass tank and enters the modification chamber, and the other end exposes the plexiglass tank and is sealed with a Teflon sleeve outside the tube-shaped metal electrodes. It passes through the polytetrafluoroethylene sleeve to communicate with the active gas source, and the outside of the quartz tube communicates with the inert gas source. There are holes at the bottom of the end of the quartz tube. In the modification chamber, there are rows of fibers perpendicular to the bottom holes of each row of quartz tubes. The wire and tubular metal electrodes are connected in parallel to the high-voltage end, and the low-voltage end is connected to the conductive sewage solution electrode. The conductive liquid of the present invention is used as an external electrode, has a cooling discharge system, reduces energy consumption, and avoids the phenomenon of arcing caused by the short circuit of the two electrodes caused by the reflected plasma; at the same time, the liquid electrode avoids the use of a metal electrode that is different from the expansion coefficient of the medium. The phenomenon of medium rupture occurs.

Description

technical field

[0001] The invention relates to a method and a device for generating an atmospheric pressure dielectric resistance plasma torch array. Background technique

[0002] In traditional plasma research, plasma generation under vacuum conditions has always occupied a dominant position. Recently, atmospheric pressure low-temperature glow plasma source has attracted more and more attention of scientific researchers because of its advantages such as no need for expensive vacuum devices, simple system, and convenient operation. So far, many atmospheric pressure glow plasma sources have been designed, and their frequencies range from 50 Hz of direct current to 2.45 GHz of microwave. These discharge sources have shown good application prospects, such as for sterilization, ozone generation, plasma Display screen, surface modification, waste water and waste gas treatment, etc. However, the external electrodes of these discharge systems are all metal, and are covered or pl...
