Drawings
Fig. 1 is a schematic structural diagram of an accumulated potential type disinfection system according to an embodiment of the invention.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, the present embodiment provides an accumulated potential sterilization system 10, including: a sterilizing cabinet 12, a gas ozone generating device for sterilization, and a gas discharging device for sterilization.
A plurality of disinfection baskets, represented by disinfection basket 14 in fig. 1, are placed in the disinfection cabinet 12, and a plurality of holes are formed in the side edges and the bottom edge of the disinfection basket, so that the gas in the disinfection cabinet 12 can penetrate through the disinfection basket 14. The material of the disinfection basket 14 itself is a conductive material, such as: stainless steel, titanium alloys, copper alloys, aluminum alloys, and the like. The preferred material is stainless steel.
The surfaces of the sterilization basket 14 that contact the sterilizer 12 are separated by an insulating material, which is typically a rubber material. Other insulating materials are also possible. As shown in FIG. 1, the opposing sides of the sterilization basket 14 each have a threshold 16, and an insulating material 18 is attached under the threshold 16, so that the electrical potential transmission between the sterilization basket 14 and the sterilization cabinet 12 is insulated. Here, the insulation means that the positive pole of the 1.5 volt direct current is connected to the sterilizing basket 14. The sterilization basket 14 will display a voltage on the voltmeter of approximately 1.5 volts, but the sterilizer 12 does not. The sterilization basket 14 is placed with the articles to be sterilized, such as a row of masks 20 placed in the sterilization basket 14. The present embodiment is not limited to the placement of the sterilization basket 14 within the sterilization cabinet 12, as long as the electrical potential conduction between the sterilization basket 14 and the sterilization cabinet 12 is maintained to be insulated.
The sterilizing gas is preferably a mixed gas of ozone and oxygen. It is also possible to use a mixed gas of ozone and air, but the concentration of ozone generated will be low. The ozone generating device for disinfection comprises the following ozone generating modes: the ambient air is compressed by the compressor 22, then the moisture of the compressed air is removed by the dehydrator 24, then the nitrogen and oxygen in the compressed air are separated by the molecular sieve 26, the oxygen is retained, the nitrogen and oxygen are discharged, then the oxygen is led into the discharge tube 28, the ozone is generated under the high-voltage electric shock, the mixed gas of ozone and oxygen is formed, and the mixed gas enters the disinfection cabinet 12 through the pipeline and the air inlet valve 30. The intake valve 30 may be manually, electrically, or pneumatically operated.
And in the aspect of exhausting, the gas-discharging device for sterilization includes: an exhaust valve 32 is further connected to the outside of the disinfection cabinet 12, the exhaust valve 32 is connected to a vacuum pump 34 through a pipeline, a filter screen 36 is connected to the rear of the vacuum pump 34, and the filter screen 36 can collect discharged solid matters. The exhaust valve 32 may be manually, electrically, or pneumatically operated. When the exhaust valve 32 is opened, the vacuum pump 34 can pump the air and floating solids in the sterilizer 12, so as to form a negative pressure in the sterilizer 12, and after the solids are collected by the filter 36, the excess air is exhausted.
The venting aspect of the overall cumulative potential sterilization system 10 operating mode is: first, the sterilization basket 14 is placed with the article to be sterilized, such as the mask 20, and the cabinet 12 is closed. Then, the negative pressure operation is started, the exhaust valve 32 and the vacuum pump 34 are opened, the negative pressure is formed in the disinfection cabinet 12, and after a certain negative pressure is reached or a certain time of negative pressure operation is passed, the exhaust valve 32 is closed. The preferred range of negative pressure is-1 KPa to-95 KPa. Then, the ozone supply operation is started, i.e. the compressor 22 is started, the air is filtered by the compressor 22, the dehydrator 24 and the molecular sieve 26, and the remaining oxygen enters the discharge tube 28 to form a mixed gas of ozone and oxygen, and then enters the disinfection cabinet 12 through the air inlet valve 30. When the gas pressure in the disinfection cabinet 12 and the gas pressure at the outlet of the gas inlet valve 30 reach equilibrium, the new ozone and oxygen mixture cannot enter the disinfection cabinet 12. At this time, the exhaust valve 32 is re-opened, since the vacuum pump 34 draws a gas larger than the intake air amount from the intake valve 30, part of the gas in the sterilizing cabinet 12 is drawn to a predetermined negative pressure, and then the exhaust valve 32 is closed. The exhaust valve 30 continues to input new mixed gas of ozone and oxygen, and when the gas cannot be input into the disinfection cabinet 12 due to pressure balance, the exhaust valve 32 is opened again to extract part of the gas in the disinfection cabinet 12 to form negative pressure, and then the exhaust valve 32 is closed. This repeated opening and closing of the vent valve 32 causes the pressure within the sterilizer 12 to repeatedly create positive and negative pressures. Positive pressure refers to atmospheric pressure above the environment, while negative pressure refers to atmospheric pressure below the environment. After a certain number of cycles of positive pressure and negative pressure, the disinfection and sterilization operation is completed. The number of the certain periods depends on the kind and the number of the objects to be treated.
The disinfecting function of ozone in the disinfection cabinet 12 is mainly divided into two aspects. Firstly, ozone has extremely strong oxidation, oxidizes and kills the original bacteria, and redundant oxygen atoms can be automatically recombined into common oxygen molecules in the sterilization process. Without any toxic residues, the activity of ozone is generally approximately 20 to 30 minutes. Ozone has strong killing ability to various bacteria including hepatitis virus, colibacillus, green dense bacillus, etc. and is effective to kill mycin. The sterilization mechanism and process of ozone belongs to biochemical process, and the ozone oxidizes and decomposes cell walls, internal glucose, DNA, RNA, protein, lipid and the like, so that bacteria can be killed due to the incapability of metabolism and reproduction.
In fig. 1, the ozone-containing gas mixture entering through the gas inlet valve 30 is diffused and distributed in the space of the sterilizing cabinet 12, and the ozone-containing gas mixture is easily exposed to the surface of the ozone on the inner surface of the sterilizing cabinet 12 and the surface of the object to be treated in the sterilizing basket 14, thereby sterilizing the object. The choice of opening the sides and bottom of the sanitizing basket 14 increases the chance of ozone contact with the item to be treated. The ozone adding concentration and adding time can be adjusted according to the types of viruses and pathogens. For example, the hepatitis B surface antigen can be eliminated when the ozone is administered for 20 minutes at a concentration of 10 mg/cubic meter. The killing efficiency is 99.99%.
However, if the mask 20 is arranged as shown in fig. 1, ozone is not easily exposed to the surface of some parts, and the oxidation-reduction potential of ozone on the other hand is used to assist the sterilization function.
The very strong oxidizing properties of ozone result from its high reduction potential. The standard electrode potential of ozone is 2.07V, and the standard electrode potentials of hydrogen peroxide, permanganate ion, chlorine dioxide, chlorine, and the like are, respectively: 1.78V, 1.67V, 1.50V, 1.36V.
Some of the ozone molecules in the disinfection cabinet 12 pass through the holes of the disinfection basket 14 and directly disinfect and sterilize the mask 20, and some ozone excess electrons are directly absorbed by the disinfection basket 14 when contacting the disinfection basket 14. Because the sterilization basket 14 is electrically conductive and the mask 20 is electrically non-conductive. Redundant electrons are transmitted and accumulated on the mask 20, one electron provides a potential not higher than 2.07V, although the electric quantity is small, new ozone is continuously supplemented in a continuous positive pressure and negative pressure operation period, the total amount of the electricity on the mask 20 is continuously increased, and when the total amount of the accumulated electrons reaches a certain degree, the mask has the function of disinfecting and sterilizing bacteria and other pathogens.
Generally, bacteria can conduct or withstand an environment with a potential of about 0.5V, and when the potential exceeds 0.7V, or more strictly, 1V, the cell wall of the bacteria, the proteins, lipids, ribonucleic acids, etc. therein are influenced by the potential and are unable to perform normal metabolic production and reproduction. Bacteria and mycoplasma have many positive and negative substances, and when the periphery of the bacterial cell wall is accumulated and covered with high reduction potential, namely negative electrovalence. The inside of the cell wall will be flooded with many ions of positive electrovalence, such as mineral ions. When the pressure is suddenly changed from positive pressure to negative pressure, water molecules in the cell wall are extruded to the cell wall due to the negative pressure, and the original accumulated potential is added to break the cell wall or damage proteins and lipids in the cell wall, so that the cell wall can not normally survive and reproduce.
Therefore, when the accumulated electric quantity of the mask 20 in the disinfection basket 14 reaches a certain quantity and the accumulated electric potential exceeds 0.7V, bacteria, viruses and the like will be mutated in vivo and killed by matching with the operation of negative pressure.
The accumulated potential type disinfection system 10 provided by the invention has the advantages that ozone is utilized to directly disinfect and sterilize, accumulated potential is generated on objects to be treated, and when the accumulated potential exceeds the range which can be borne by pathogens, the pathogens generate variation in vivo and are killed by matching with the operation of negative pressure.
If the item to be treated in the sterilization basket 14 is other electrically conductive item or device, the operator may have two options. Firstly, ozone is directly contacted with the surface of the object to be treated, and the ozone is disinfected and sterilized by the strong oxidizing capability of the ozone. Secondly, the insulating material is filled between the objects to be treated and the disinfection basket 14, and the objects to be treated are also isolated by the insulating material, so that the respective objects to be treated can respectively accumulate the total electric quantity and the electric potential.
Therefore, in the space of a closed disinfection cabinet 12, the mixed gas of ozone and oxygen is input, the total electricity content and the electric potential of the surface of the object to be treated can be accumulated by using an insulating material, and the ozone-induced two sterilization functions are matched with the periodic operation of positive pressure and negative pressure, so that the disinfection and sterilization can be efficiently carried out under the two sterilization functions of ozone introduction, including direct contact oxidation and conduction of the reduction potential of ozone to the object to be treated, and when the accumulated potential exceeds the range of pathogenic energy, the pathogen generates variation in the body and is killed by matching with the operation of periodic negative pressure.
The alternate opening and closing of the inlet valve 30 and the outlet valve 32 causes the cabinet 12 to cyclically operate with positive and negative pressure.
It can be seen that, with the use of the above-mentioned system 10, the present embodiment also provides an accumulated potential type disinfection method, which includes: placing a disinfection basket with conductive performance in a disinfection cabinet, wherein the disinfection cabinet is in insulated connection with the disinfection basket, and placing a to-be-disinfected object in the disinfection basket with holes formed in the side edge and the bottom;
opening an air inlet valve between the disinfection cabinet and the discharge tube, compressing air in a compressor, removing moisture by a dehydrator, separating nitrogen and oxygen by a molecular sieve, introducing the separated oxygen into the discharge tube, generating ozone, and inputting the ozone into the disinfection cabinet through a pipeline;
adjusting the concentration and input time of ozone input into the disinfection cabinet according to the types of viruses and pathogens, and when the gas pressure in the disinfection cabinet and the gas pressure at the outlet of the air inlet valve reach balance, forming positive pressure in the gas in the disinfection cabinet and opening an exhaust valve between the disinfection cabinet and the vacuum pump;
the vacuum pump pumps gas and floating solid matters in the disinfection cabinet, the filter screen permeates the gas and collects the solid matters, the exhaust valve is closed after the gas in the disinfection cabinet forms negative pressure, and the intake valve is opened again;
the gas in the disinfection cabinet is subjected to periodic operation of a certain number of positive pressures and negative pressures to complete disinfection and sterilization operation.
In summary, in the accumulated potential type disinfection system and method according to the embodiments of the present invention, the total amount of the charges on the object to be disinfected is continuously increased by using the ozone disinfection gas to disinfect the object to be disinfected in the disinfection basket, the disinfection cabinet is in insulated connection with the disinfection basket, the disinfection basket is an electric conductor, the input of the disinfection gas is circularly started, and the discharge of the disinfection gas is circularly started, so that the accumulated total amount of the electrons reaches a certain degree, and the accumulated total amount of the electrons can perform a disinfection and sterilization effect on bacteria and other pathogens on the object to be disinfected. Short resolving time, simple operation, quick effect and low cost.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
