Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] During the formation of plasma, electrons obtain energy from the electric field. High-energy electrons will continuously collide with atoms and molecules, and a series of photochemical reactions will occur between them. When they return from the excited state to the ground state, an emission spectrum will be generated.

[0026] The wavelength of light waves generated by plasma is usually in the range of 180nm-1000nm, including ultraviolet light, visible light and infrared light. Among them, the wavelength of ultraviolet light is 180nm-400nm, which can be divided into long-wave UVA, medium-wa...

Abstract

The invention discloses a plasma activity enhancement method and a plasma generation device. The invention has a core that a focusing unit which carries out focusing on light wave corresponding to plasma is added or designed on the plasma generation end of the plasma generation device; the focusing unit is set as a concave reflecting mirror; the inner side of the reflecting mirror can be coated with a metal film or a dielectric film; the generated plasma is focused in an area near the focal point of the reflecting mirror under the function of the reflecting mirror, and energy loss caused whenthe plasma is generated and radiated to the periphery is reduced; meanwhile, the plasma which is focused in a focal point area is large; and a mutual collision probability of photons, atoms, moleculesand the like contained in the plasma is large, and physical chemistry reaction among all plasma is accelerated so as to enhance the activity of the plasma.

Description

technical field [0001] The invention belongs to the field of plasma technology, and more specifically relates to a plasma activity enhancement method and a generating device. Background technique [0002] Plasma is the "fourth state" of matter, and it is a quasi-neutral gas composed of charged particles and neutral particles showing collective behavior. According to its system temperature, it can be divided into two categories: high-temperature plasma and low-temperature plasma. [0003] In the plasma discharge process, electrons get energy from the electric field, and high-energy electrons generate active free radicals, electrons, ions and other components through collisions with neutral gases, in which the substances in the plasma are alone or interact with each other, in biomedicine can play an important role. For example, charged particles can inactivate germs and are important substances for sterilizing blood coagulation and descaling material surfaces. Neutral subst...
