Description

Plaster filter unit for self sterilization {PLASMA FILTER UNIT}

The present invention relates to a self-sterilizing plasma filter unit capable of removing microorganisms and sterilization of harmful bacteria or bacteria in the air by using various three-dimensional plasma cells.

At present, as the industry is highly developed, the air is seriously polluted, and the amount of fine bacteria such as various dusts, soot, and bacteria living in dust, and the amount of harmful gases are increasing greatly. It causes serious problems such as various respiratory diseases and secondary infections caused by bacteria. In addition, among toxic gases, volatile organic compounds (VOCs) inevitably generated in various processes such as production processes, waste treatment processes, and coating processes that use a large amount of various organic solvents cause photochemical oxidation reactions, resulting in serious It is a substance that causes pollution problems.

However, the method of purifying contaminated air includes a method using a filter including a sea wave filter, a method using water adsorption force, a method by corona discharge using an electrostatic precipitator, a method using a photocatalyst including TiO2, and a method using atmospheric pressure plasma. Etc. can be mentioned. The plasma is to apply electrical energy to the gas to form a fourth material state, which can be said to be a physical definition of a group of quasi-neutral gases of neutral particles and charged particles.

On the other hand, compared with high temperature plasma, other characteristics of low temperature plasma are characterized by having a greater proportion of electronic energy than ionic energy, and collectively refer to plasma generated even in an open environment in the atmosphere rather than in a closed vacuum environment. do.

The source of the high temperature plasma is a thermal spray of inert gas that generates high thermal energy using high frequency power or direct current power, and sprays the metal on the target material and the plasma vapor phase by melting the material in a vacuum environment and depositing the material on the target material. It is used for deposition, metal welding and cutting.

Low-temperature plasma has higher electron energy than ionic energy because the energy of plasma generated in the atmosphere is higher than that of ion energy. Therefore, the plasma has low contact heat and high electron activity. . Although research is being conducted on the atmospheric environment, there is a disadvantage of limited energy range compared to the high cost of producing a plasma source. Therefore, it is necessary to expand the plasma energy peak region at low cost and to cope with the amount and velocity of the mobile phase. Low-temperature plasma sources must be developed.

1 is a view for explaining a self-sterilizing plasma filter unit according to an embodiment of the present invention, Figure 2 is a perspective view showing a plasma cell in the self-sterilizing plasma filter unit of the present invention. The present invention is a self-sterilizing plasma filter unit capable of removing sterilization and fine dust of harmful bacteria or bacteria in the air by using a plurality of plasma cells 20 arranged in the storage box 10 as a plasma filter. .

The plasma cell 20 is cylindrical having a threaded portion 25 penetrating and corrugated along an inner diameter, the one or more electrodes positioned near the surface of the threaded portion 25 and one or more electrodes positioned near the electrode. It contains another electrode. At this time, when the high voltage electrode is caught across the electrodes, a plasma is generated to sterilize or decontaminate at least a portion of the screw surface.

In the storage box 10, a plurality of plasma cells 20 are arranged as, for example, 7 * 8, and used as a self-sterilizing plasma filter. In some cases, the storage box 10 may be used in a large or small number. Alternatively, the inner diameter may be modified into a hexagonal or octagonal plasma cell instead of the screw portion of the plasma cell 20.

Thus, a surface, such as the screw surface of the plasma cell 20 shown in FIG. 2, can sterilize certain objects located on the surface as well as itself. In this way, embodiments of the present invention may include one or more objects made of a suitable material and sized on a storage box such that the storage box or other structures and objects with self-sterile surfaces can be sterilized. .

In another particular embodiment, a peak-to-peak AC voltage of 2-20 kV may be applied, and in more detailed embodiments the AC voltage is a 1-50 kHz RF voltage.

For example, the self sterilizing laminate surface of the plasma cell may have a dielectric layer located between the two electrode layers, and the ground electrode layer is located away from the layer of powered electrode. The power electrode and the ground electrode form an intersecting pattern, and the driving of the power electrode with the voltage to the ground electrode produces a plasma that sterilizes or decontaminates the active surface.

The electrodes may have various shapes and sizes, and in various embodiments, the electrodes may be exposed to an environment in contact with the surface, the electrodes may be embedded in the surface, and the electrodes may be hydrophobic between the electrode and the environment. It may have a layer of material such as a thin insulating layer, Teflon or a dielectric material layer, or the electrode may be structured by a combination of exposure, embedding and coating.

It is also possible to have a coating on the electrode so that the electrode is not exposed to the environment, and the outer surface of the coating can be sterilized through the plasma generated by the electrode via an electrical field passing through the coating.
