Xenon excimer ozone external circulation spraying system in freezing environment

Technical Field

The invention relates to the technical field of xenon excimer light source ozone spraying, which is a specific application of a concentrated transmission type xenon excimer light source ozone generator and a specific design of an ozone spraying framework of the concentrated transmission type xenon excimer light source ozone generator. The ozone sterilizing system designed by the invention can not generate harmful oxynitride gas, so that the sterilized food can not be corroded by the oxynitride gas.

Background

Currently, particular human attention is paid to the importance of airborne viral killing on the environment. As the virus is transmitted through the air by taking aerosol in the air as a carrier, obviously, the sterilization of the environmental space of human life by adopting a more effective, faster, safer and more environment-friendly sterilization mode is the best means for effectively inhibiting the transmission of the virus.

It is well known to those skilled in the art that the order of choice for the environmental disinfection method should generally be ozone disinfection > chlorine dioxide disinfection > liquid chlorine disinfection > hypochlorite disinfection. According to the related sterilization technical regulations, the chloride disinfectant used for the disinfection of the environmental surface is metered by chlorine, the content of the chlorine is 1000mg/L, the control limit of safe underground water to the chlorine is 0.01mg/L, and the effective dosage of the disinfection is 10 ten thousand times different from the allowable safe limit of the underground water source. The substance of the law of substance extinction generally refers to chemical elements, no matter what kind of chloride disinfectant is converted into any other chlorine-containing compound after being used, the used chlorine element does not disappear, and the chlorine element sprayed to the ground inevitably enters the ground and gradually enters a surface water layer, so that the monitoring of the chlorine element in soil and underground water is always an important detection item for an environment detection department. Similarly, bromine-containing disinfectants are also used in the environment, and the consumption dosage of the bromine is 10 ten thousand times different from the safe allowable amount of underground water bromine.

However, the globally accepted green, broad-spectrum, highly effective, non-chemical ozone disinfectants, while being uneconomical in their speed and effectiveness against harmful microorganisms, are confined to the embarrassment of heroes. The reason for this is that ozone is unstable due to its activity, and therefore, it must be prepared as it is. From the viewpoint of cost and current production, the method of preparing ozone from air as a gas source has been a hot spot of attention and effort for researchers and merchants.

At present, the most widely used method in China for preparing ozone by taking air as an air source is the equipment for preparing ozone by exciting oxygen in the air by corona (namely dielectric barrier discharge), which is also called as a plasma method. Through technical research, the inventor knows that the ionization potentials of nitrogen and oxygen are close to each other because the nitrogen in the air is about 3.7 times that of the oxygen, the ionization potential of the nitrogen is 15.5eV, and the ionization potential of the oxygen is 12.5 eV. Therefore, while ozone is prepared by ionizing oxygen in the air in a corona manner, nitrogen in the air is ionized to generate oxynitride. Meanwhile, in the field of plasma academia, the academia does not agree on the standard of plasma, so compared with the plasma state of a single element in a vacuum state, the plasma state in the air is not considered to be the plasma state which can be achieved by many scholars, and is only close to the plasma, so that the term of secondary plasma is generally accepted by the academia in the air environment. The effect of the "secondary plasma" state is that it is difficult to ionize only one element of space, and the spectral band of the corona produced is relatively wide. For the technology of preparing ozone by plasma, the energy generated by a high-voltage electrode is difficult to accurately position at about 15.5ev energy level which only allows oxygen molecules to ionize, and the emitted corona spectrum is wide, so that nitrogen molecules in the air cannot be ionized and cannot absorb broadband ultraviolet radiation generated by corona, and therefore, ionized nitrogen atoms are inevitably mixed in the method of preparing ozone by adopting corona ionized air. Nitrogen is excited to form oxynitride with complex components. Nitrogen oxides are therefore a generic term for the relatively complex and very reactive harmful gases, the main representatives of which are nitrogen monoxide (ev ═ 9.5) and nitrogen dioxide (ev ═ 11.0) and dinitrogen oxide (ev ═ 12.9). The nitrogen oxides can react with ozone to consume the prepared ozone so as to reduce the concentration of the prepared ozone gas, and can react with oxygen to generate nitrogen oxides, and the nitrogen oxides generate an acidic solution when contacting water, for example, nitrogen dioxide reacts with water to generate nitric acid. Although the acidic substances generated by the oxynitride can kill some microorganisms, compared with the environment destruction and ozone depletion, the ozone killing effect is weakened, the harm is far greater than the benefit. The most troublesome technical problem is that most of the existing ozone sensors are not good in specificity for detecting ozone and oxynitride gases, so that the effective content of the concentration of ozone prepared by adopting corona to ionize oxygen in air is difficult to identify, so that equipment for preparing ozone by adopting corona to excite oxygen in air is common, and the marked prepared ozone has strong capability, but the ozone sensor has no better popularization and popularization in the field of ozone disinfection. The reason for this is that the nitrogen oxide gas generated simultaneously reduces the effective concentration of ozone, and the harmful gas and acidic solution generated have a great harmful effect on the living things and the environment.

A revolutionary technology for preparing ozone from an air source is a new technology for preparing ozone by using 172nm ultraviolet narrow-frequency ultraviolet light emitted by a xenon excimer light source. The absorption of oxygen to the ultraviolet narrow-frequency light of 172nm is 20 times higher than that of the ultraviolet narrow-frequency light of 185nm, so that the ultraviolet narrow-frequency light of 172nm emitted by xenon excimer molecules can excite oxygen in the air to generate a large amount of active oxygen with higher efficiency, and the strong oxidizing power which exceeds a low-pressure mercury lamp by dozens of times decomposes organic substances into carbon dioxide and water, so that the high-efficiency xenon excimer laser has stronger killing capability exceeding all killing agents. This air source ozone generation does not generate nitrogen oxides since nitrogen does not absorb the ultraviolet narrow-band light at 172 nm. This is the current ozone production technology that produces ozone gas from air most efficiently, produces the purest ozone gas, and does not produce harmful nitrogen oxide. The equipment for preparing ozone by exciting oxygen by using a xenon excimer light source is called a xenon excimer ozone generator.

At present, the ozone sterilizing equipment developed by the xenon excimer light source ozone generator is single in product, and only one product is developed and applied at present. The working principle of the product is that the xenon excimer lamp of the xenon excimer light source is arranged in an open metal (304 or 316 stainless steel metal) cover (also called as a metal cabin), air in the environment is sequentially conveyed to the periphery of a xenon excimer lamp in a metal container through an axial flow fan, 172nm narrow-frequency ultraviolet light emitted by the xenon excimer lamp excites oxygen molecules in the air to generate active oxygen atoms, the active oxygen atoms have extremely strong oxidability, volatile Organic Compounds (VOC) in the air sequentially conveyed to the body can be subjected to oxidation reaction to degrade the VOC, and harmful microorganisms suspended in the air and coexisting with the VOC can be oxidized and killed by active oxygen to generate carbon dioxide molecular gas and water molecules which are volatilized into the surrounding air without generating other chemical substances, so that the air is called as an environment-friendly disinfectant. Because the sterilization product developed by the xenon excimer light source ozone generator adopts the axial flow fan with weak wind power and weak guidance, and the inlet container for accommodating the xenon excimer light source lamp tube is non-closed and can disperse air flow to the periphery, the ozone gas generated after the periphery of the xenon excimer light source lamp tube is excited is spread to the periphery in a dispersion spreading mode and meets the air with VOC sent by the axial flow fan to generate oxidation reduction reaction with the VOC to play a sterilization role. The inventor refers to the metal chamber provided with the xenon excimer light source lamp tube as an open xenon excimer ozone excitation chamber.

The inventor refers to the application mode of the ozone disinfection product developed by using the open xenon excimer ozone excitation chamber as a dispersion propagation type xenon excimer ozone generator. In the technical research, the 'dispersion propagation type xenon excimer ozone generator' is found to accumulate a large amount of superfine powder near a xenon excimer lamp after being used soon, and the dust removal effect of the xenon excimer ozone generator is caused. When dust particles exist in the air of the killed space, active oxygen generated by exciting the air by the xenon excimer lamp and the dust particles are adsorbed together to be gathered into larger dust particles, and when the volume of the dust particles is increased by gathering the active oxygen, the larger dust particles fall onto a lamp tube of the xenon excimer lamp, the vicinity of the lamp and a fan for conveying air. This is a very unfavorable phenomenon! Because the 172nm narrow-frequency ultraviolet light excited by the xenon excimer lamp tube is quickly attenuated when the ultraviolet light is spatially transmitted, the range of effective excitation of oxygen molecules to generate oxygen atoms is within 2-4 mm from the lamp tube of the xenon excimer light source, the distance is too far, the intensity of the 172nm ultraviolet narrow-frequency light emitted by the xenon excimer lamp tube is attenuated, the peripheral oxygen molecules cannot be excited to generate oxygen atoms, and therefore ozone gas is generated. Except in clean air environment, most of the environment air needing to be killed has more or less micro dust particles, so the phenomenon that the 'dispersion propagation type xenon excimer ozone generator' collects dust around the lamp tube in use occurs sooner or later in the service life of the xenon excimer lamp tube, which limits the application occasions of the 'dispersion propagation type xenon excimer ozone generator' and greatly shortens the service life of the lamp tube compared with the design service life of the lamp tube. Although the product of the dispersion propagation type xenon excimer ozone generator obtains good benefits after being put on the market, the product plays a good role in air disinfection and VOC odor elimination in places such as hospitals, food processing factories, nursing homes and the like. The xenon excimer ozone disinfection cabin is developed by people to be used for medical instruments, medical supplies (such as sickbeds and the like) and the like, and the good effect is also exerted. However, in the case where fine dust is generated, the defect that the capability of producing ozone is greatly reduced due to dust collection is gradually revealed as the product is applied. Therefore, the xenon excimer light source ozone generator is used for developing new follow-up disinfection products, the best ozone preparation technology of the xenon excimer light source ozone generator is developed to a higher application level, so that the disinfection effect of ozone is developed to an unrivaled effect, and the purpose of the inventor for proposing the patent application is provided.

Some virus experts believe that in a frozen environment, activities of harmful microorganisms of the bacterial type are inhibited, but harmful microorganisms of the viral type do not die due to low temperature but rather easily survive. Particularly, the freezing storage and freezing transportation links of meat and seafood are the sources of the survival and transmission of viruses. In the aspect of how to kill viruses in frozen foods, although sodium hypochlorite, electrolyzed oxidizing water and chlorine dioxide can be used as the food disinfectant, the chlorine ions and the acidic solution generated by the disinfectant obviously cause great risks for food preservation and food safety. Ozone sterilization is currently used for the disinfection of tableware and is not used for the disinfection of food, but ozone is used for food preservation, such as meat, eggs, vegetables, fruits and the like, is commonly used and has long service life, and the ozone is proved to be very safe. It is known that active oxygen atoms (i.e., ozone) have a killing power 300 to 1000 times higher than that of chlorine, and are the most environmentally friendly and most effective disinfectants, but up to now, no consideration has been given to the killing of viruses in frozen foods. The reason is simple, namely, the ozone is neglected in the current sterilization application of epidemic frozen food due to the laggard existing technology of ozone. The reason for this is because the existing ozone equipment can twinen more oxynitride at the same time, and the corrosiveness of the oxynitride to the food cannot be underestimated. Another reason is that the method of use of ozone is solidified, resulting in the development of new ozone equipment that does not keep up well with the needs of cold environments and the sterilization of frozen foods in epidemic situations.

Based on this, the inventor also provides the invention application of the concentrated transmission type xenon excimer light source ozone generator and the ozone spraying framework of the concentrated transmission type xenon excimer light source ozone generator on the same day as the filing of the utility model. Therefore, the technical content expressed in the patent application document is the specific application of the technology expressed in the invention patent application of 'concentrated transmission type xenon excimer light source ozone generator' and 'ozone spraying structure of concentrated transmission type xenon excimer light source ozone generator' to ozone disinfection in a freezing closed environment.

Disclosure of Invention

The inventor also submits an invention patent application document of 'concentrated transmission type xenon excimer light source ozone generator' on the same date of submitting the patent application. The core technology expressed by the patent application document is that a closed xenon excimer ozone excitation chamber and a basic framework thereof are developed by utilizing a xenon excimer light source. The technical core expressed by the patent document is summarized by simple language, namely, a xenon excimer lamp tube of a xenon excimer light source is placed in a closed container with air holes at two ends, one end of each hole is connected with a gas source device capable of providing a certain pressure, and the other end of each hole is connected with a pipeline for conveying airflow. When the xenon excimer lamp tube works, oxygen molecules in peripheral gas flow are excited to generate active oxygen atoms with strong oxidizing property, and then mixed gas (mainly mixed gas consisting of ozone and nitrogen) consisting of ozone and other components in the gas flow is formed. The formed mixed gas containing ozone is blown out from the closed container under the action of air pressure, then the mixed gas is guided along the air pipe and is intensively conveyed to a required position, and the ozone mixed gas with the concentration basically consistent with that of the ozone in the closed chamber is formed at the outlet of the pipeline. Under a certain air pressure, the air flow flowing through the closed xenon excimer ozone excitation chamber and the pipeline is constant, and the concentration of ozone in the air flow depends on three basic factors, namely the power of a xenon excimer lamp, the lighting time and the number of the xenon excimer lamps connected in series and in parallel in the air path (namely the closed xenon excimer ozone excitation chamber). Regarding the design technical characteristics of the 'closed xenon excimer ozone excitation chamber', the applicant has already expressed in the invention patent application document of the 'concentrated transmission type xenon excimer light source ozone generator', and the patent application only takes the 'closed xenon excimer ozone excitation chamber' in the 'concentrated transmission type xenon excimer light source ozone generator' as a component and is applied to the system of the ozone spraying framework of the concentrated transmission type xenon excimer light source ozone generator expressed in the patent.

The present invention features that the external xenon excimer ozone circulating spraying system in freezing environment consists of sealed xenon excimer ozone exciting cabin, pressure gas source feeder, gas filter, gas pressure regulating valve, Venturi tube and one fluid nozzle as essential parts, and may be combined with air pump and/or molecular sieve oxygen producing machine and solenoid valve as basic components to form the basic structure of ozone spraying system. The closed xenon excimer ozone excitation chamber provided with the xenon excimer lamp tube can be used in a plurality of combinations in series, parallel or series-parallel in a framework system. The molecular sieve oxygen generator is used as one of the pressure air sources of the framework system, the air pump is used as the second pressure air source of the framework system, and the air pressure provided by the air pump is higher than the air pressure of the oxygen outlet of the molecular sieve oxygen generator. In order to reduce the oxygen temperature of the oxygen generator and the temperature of the xenon excimer ozone excitation chamber, the backflow gas in the closed freezing environment can be used as the outlet oxygen of the molecular sieve oxygen generator and the cooling gas of the closed xenon excimer ozone excitation chamber.

The external xenon excimer ozone circulating spraying system in freezing environment is suitable for the structural design of humidifying ozone sterilizing system in refrigerator and freezing transport vehicle.

Detailed Description

While the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.

Example figure 1 is a design of the present invention, a specific design of a spray configuration of a fluid nozzle for xenon excimer ozone vapor mist. In fig. 1, 1 is a closed xenon excimer ozone excitation chamber, also called an ozone production module; 2 is an air pump; 3 is a molecular sieve oxygen generator, also called as an oxygen generating module; 5 is a pressure gauge; 6 is a throttle valve; 7 is a pressure regulating valve; 8 is a venturi tube; 10 is an air pre-filter; 12 is a one-way valve; 13 is a fluid nozzle; 16 is a cooling module; 17 is a flow meter; 18 is a comprehensive function filter, which is used for filtering water vapor and fine dust, and mainly filters the return air returned to the xenon excimer ozone preparation equipment to avoid the phenomena of frosting and dust collection on the xenon excimer lamp tube; 19 is a solenoid valve; 25 is a water tank (also representing a tap water supply, or a pressurized water source); the gas line, water line, and water-gas line are shown by dotted lines, solid lines, and dotted lines, respectively. In fig. 1 a is shown a refrigerated enclosure, which may be a freezer compartment, a refrigerated compartment of a refrigerated transport vehicle, a freezer cabinet, or similar refrigerated enclosures.

Figure 1 is a high gas-water ratio design because the molecular sieve oxygenator can only provide about 0.2MPa (2kg) of gas pressure on the ozone production gas path. The pressure of the spray is mainly from the gas pressure provided by the gas pump, and no liquid phase exists in the system, because the steam spray cannot be implemented in a freezing environment, otherwise, the steam spray can be frozen, and even the spray nozzle can be frozen.

The working principle of fig. 1 is that high-pressure air from an air pump and high-concentration ozone gas from an oxygen generator and a xenon excimer ozone excitation chamber are mixed by a venturi tube and then enter a fluid nozzle in a freezing closed space through a pipeline, and the high-concentration ozone gas is delivered into the freezing closed space. The air inlet port of the air pump of the system (equipment) and the air inlet port of the oxygen generator are connected with the closed freezing environment through an air pipe, and the air inlet of the system is provided by the freezing air of the freezing environment. Therefore, the system can continuously prepare ozone under the working state, the ozone gas is continuously conveyed into the freezing environment, and meanwhile, the gas in the freezing environment is also used as a gas supply source of the system (equipment), so that the concentration of the ozone in the freezing environment is continuously accumulated along with the preparation time of the ozone in the system, the concentration of the ozone which can kill harmful microorganisms (bacteria and viruses) is always reached, and the concentration is maintained for a certain time (generally, the maximum concentration is within 120min, and is determined according to the killing effect of a reagent).

For the sterilization of the freezing environment of the system (equipment) outside the freezing environment, the problem that the nozzle is frozen is avoided because ozone vapor spray is eliminated and only ozone gas spray is adopted. However, there is a problem that a cold air flow from a freezing environment generates moisture (humidity) when it comes out of the freezing environment. Cold water gas in the backflow gas can cause frosting of the xenon excimer lamp tube, and ultraviolet light with the influence of 172nm radiates outwards. The technical scheme for solving the question lies in that cold air from a freezing environment is led into a cooling pipeline of oxygen generator gas through an air pipe branch, then enters a cooling interlayer of a closed xenon excimer ozone excitation cabin, and oxygen from the oxygen generator and the closed xenon excimer ozone excitation cabin are cooled through the led cooling air and then are led to an air inlet end of an air pump through a pipeline to be used as an air source of the air pump. Meanwhile, the other part of the cold air from the freezing environment directly enters the molecular sieve oxygen generator to be used as the air source of the molecular sieve oxygen generator. The air source of the molecular sieve oxygen generator also needs to remove moisture, so that the function of the air prefilter of the component 10 needs to be enlarged, a filter column for removing the moisture needs to be added, measures such as selecting a proper steam-water separator, enlarging the volume of a silica gel column and the like need to be taken, and the moisture (humidity) in the return air flow from the freezing environment is removed.

For the design of fig. 1, the molecular sieve oxygen generator may be selected from air Pressure Swing Adsorption (PSA) oxygen generator, or may be selected from adsorption vacuum desorption (VPSA) oxygen generator. The oxygen generator can be removed, and an air pump is selected. Certainly, the oxygen generator is selected to provide oxygen with higher purity to the closed xenon excimer ozone excitation chamber, the ozone preparation amount can be remarkably increased by more than three times, and the air is used for supplying air to the closed xenon excimer ozone excitation chamber, so that the ozone preparation amount is remarkably reduced because the air contains only 21% of oxygen. The omission of a molecular sieve oxygen generator obviously reduces the volume and weight of the equipment, so that the removal of the oxygen generator is a reasonable design choice in consideration of the situation that the volume and weight of the equipment are not required to be large. The oxygen supply amount of the existing molecular sieve oxygen generator is firstly distinguished by the prepared volume per minute, such as 1L/min, 2L/min, 3L/min, 5L/min, 10L/min and the like, under the condition of the supply of the molecular sieve products in the existing market, for the small molecular sieve oxygen generator, the specification of 10L/min basically belongs to the upper limit of the small molecular sieve oxygen generator, and if a large oxygen generation amount is needed, the small oxygen generation amount is modularly combined according to the model of the small oxygen generation amount. For the matching use with the xenon excimer light source, the small molecular sieve oxygen generator can be basically selected to meet the requirement, because the xenon excimer light source excites the oxygen to prepare the ozone, which belongs to high-end miniaturized ozone preparation equipment. The medical disinfection and sterilization device can basically meet the requirements of various occasions corresponding to the prior medical disinfection and sterilization. For the occasion with low requirements, a molecular sieve oxygen generator can be omitted, and an air pump is directly used for providing a pressure air source for the closed xenon excimer ozone excitation cabin.

For the design of fig. 1, when a high amount of ozone is required to be produced in a unit time, in addition to providing high concentration oxygen by using a molecular sieve oxygen generator, in the framework system shown in fig. 1, the production amount of ozone in a unit time can be increased by using a plurality of closed xenon excimer ozone excitation chambers in a serial mode, a parallel mode or a serial-parallel mode. In this regard, the present inventors have expressed in the "concentrated transmission xenon excimer light source ozone generator" patent application filed on the same day as this patent.
