Abstract
The invention aims to overcome the problems of a peculiar odor and toxic and side effects like residues of a conventional disinfectant fluid and provides a preparation method for a disinfectant fluid based on low temperature plasma. The preparation method comprises the following concrete steps: introducing a certain amount of working gas into a low temperature plasma generating apparatus in virtue of a physical device, i.e., low temperature plasma, and driving the low temperature plasma generating apparatus by using electricity; and weighing a certain amount of water, disposing the apparatus at a position a certain distance above or below a liquid level of an aqueous solution and exciting interaction between plasma and water, wherein after the plasma and the water interact for a certain period of time, the water turns into the disinfectant fluid based on low temperature plasma. The method provided by the invention is simple, highly efficient and environment-friendly; the disinfectant fluid has broad-spectrum high-efficiency sterilization effects and is free of a peculiar odor, corrosivity and chemical residues.
Description
Technical field
The invention belongs to the sterilized water preparation method, be specifically related to the sterilized water preparation method based on low-temperature plasma.
Background technology
Medicine equipment, the sterilization and disinfection of life and office daily necessities etc. is very important.Although present existing sterilization and disinfection product is very many, yet most product adopts the method for chemistry, and often with pungent odour is arranged, corrodibility or toxic side effect such as residual are arranged causes certain threat to HUMAN HEALTH.Be example with the chlorine-containing disinfectant, chlorine-containing disinfectant has cheapness, advantage such as efficient, is widely used in drinking water disinfection, environment disinfected, fields such as health care sterilization, be use in the world at present a class sterilizing agent the most widely.Yet chlorine-containing disinfectant has following shortcoming: (1) hypochlorous acid molecule decomposes in water and discharges gas Cl2, and gas Cl2 is contaminate environment not only, but also can cause shed tears, cough, skin irritation and mucous membrane, severe patient causes poisoning, is choked to death and dies.When working concentration was big, the people was unsuitable on the scene.Therefore, chlorine-containing disinfectant generally should not be applied to disinfection of indoor air.(2) stronger pungency is arranged, generally should not be applied to the sterilization of human body skin and mucous membrane.Therefore a kind of safe, sterilized water is to the protection environment efficiently, human body health has great importance, social benefit is far-reaching.
Plasma body is material the 4th attitude after solid-state, liquid, gaseous state, and when impressed voltage reached the firing voltage of gas, gas molecule was breakdown, produces the mixture that comprises electronics, various ion, atom and free radical.Plasma body can be divided into different classifications: by the thermodynamic(al)equilibrium classification, plasma body can be divided into thermal equilibrium plasma body and nonthermal plasma; Press the system temperature classification, plasma body is divided into low-temperature plasma and high-temperature plasma.The temperature of all particles is all the same in the thermal equilibrium plasma body, shows as high-temperature plasma on the macroscopic view.In nonthermal plasma, the temperature of electronics can be up to tens thousand of degree, and the temperature of ion and neutral particle is much smaller than electronic temp, and whole system presents low-temperature condition, so be also referred to as low-temperature plasma.Low-temperature plasma exists a large amount of, miscellaneous active particle, so nonthermal plasma can be used as the high reactivity reagent utilization in multiple practical applications.
Summary of the invention
