Description

Technical Field

[0001] The invention relates to a disinfection and sterilization device, in particular to a movable device for disinfection and sterilization using horseradish aqueous emulsion. Background Art

[0002] Horseradish is a plant-based pesticide derived from plants such as beech, mustard seeds, and horseradish. Its active ingredient is allyl isothiocyanate (AITC). It can be used for food preservation and anti-corrosion, as well as insecticides, bactericides, nematodes, and health and epidemic prevention. It is an environmentally friendly biological fumigant and the preferred biological product to replace methyl bromide internationally. Many countries in the world use it in fields such as soil disinfection. In my country, it has been widely tested and applied in the fields of grain storage, food preservation, and green pest control in facility horticulture. More than 20 years of experimental research have shown that horseradish extract has a good killing effect on hundreds of pests and diseases: it can effectively kill more than 100 common pests and mites, and the fumigation concentration for Homoptera, Hemiptera, Siphonaptera and some Diptera pests such as aphids, planthoppers, thrips, houseflies, mosquitoes, cicadas, and stink bugs is less than 1 mg / L; the fumigation concentration for storage pests such as rice weevils, corn weevils, red flour beetles, grain borers, and booklice is 1-4 mg / L; it is effective against larvae, pupae, and adults of Lepidoptera such as diamondback moth, cotton bollworm, Spodoptera litura, beet armyworm, and meal borer, with a fumigation concentration of 5-20 mg / L. Horseradish extract has high activity against 92 common bacteria and fungi. For example, the active concentration against Pythium, Rhizoctonia solani, Fusarium solani, Botrytis cinerea, Rhizopus niger, Cylindrospermum spp., Fusarium wilt, brown spot pathogen, Sclerotinia sclerotiorum, anthrax, Penicillium spp., Aspergillus niger, and rice blast fungi is 0.2-4 mg / L; the active concentration against watermelon bacterial angular leaf spot, tomato bacterial wilt, canker, scab, cabbage soft rot, pepper bacterial leaf spot, and cabbage soft rot bacteria is 0.1-2 mg / L; the active concentration against vegetable root-knot nematodes, peanut root-knot nematodes, soybean cyst nematodes, wheat grain nematodes, sweet potato stem nematodes, rice stem-tip nematodes, millet nematodes, pine wood nematodes, and citrus semi-penetrating nematodes is 0.3-10 mg / L. It has high inhibitory activity against more than 70 common weed seeds, such as barnyard grass, wild oats, wild amaranth, sowwort, foxtail, chickweed, cleaver, Persian speedwell, foxtail grass, quinoa, cyperus, cyperus dimorphus, and cyperus cardinalis, with an inhibition rate of 100% at a concentration of 20 mg / L. Its effective concentration for soil organisms such as woodlice, millipedes, and snails is between 3 and 20 mg / L.

[0003] Viruses are not living organisms, but rather protein molecules (DNA or RNA) covered by a protective layer of lipids (fat). When absorbed by cells lining the eye, nose, or cheek, their genetic code changes (mutates), transforming them into attackers and multipliers. Viruses are actually very fragile, protected only by a thin outer layer of fat. By dissolving this layer, the protein molecules disperse and break down. Horseradish extract, the active ingredient of which is allyl isothiocyanate (AITC), effectively breaks down protein molecules. Even if virus particles are floating in the air as aerosols, contact with horseradish extract destroys their protein coat and envelope in a matter of seconds, inactivating the virus. Therefore, using horseradish extract to prevent and control devastating epidemics caused by various viral infections is feasible.

[0004] The most cost-effective measure to prevent the occurrence, spread, and epidemic of an epidemic is to minimize the presence of viruses and other pathogens in places where people gather. Effective ways to reduce the presence of viruses and other pathogens include directly killing them and quickly removing them through ventilation or filtration to ensure that the air meets environmental quality standards.

[0005] Currently, hospitals and epidemic prevention systems are using a wide range of disinfection and epidemic prevention technologies, equipment, and specialized facilities. When unoccupied, central air conditioning and ventilation systems, ultraviolet radiation, ozone disinfection, electrostatic adsorption air sterilizers, chemical fumigation, or spray disinfection are often used. When occupied, central air conditioning and ventilation systems, recirculating air ultraviolet air sterilizers, and electrostatic adsorption air sterilizers are often used. Operating rooms or wards, which require the highest environmental quality, require specially designed laminar flow ventilation systems.

[0006] However, the aforementioned technologies and facilities used by hospitals and epidemic prevention systems are difficult to adapt to ordinary gathering places and homes. To effectively prevent the outbreak and widespread spread of known and unknown epidemics, minimize the spread of pathogens in gathering places, and reduce the economic losses and overall impact of epidemics on society, there is an urgent need to develop simple, cost-effective, safe, and reliable disinfection and epidemic prevention technologies and supporting devices that have minimal impact on human activities and are suitable for disinfection and epidemic prevention in various places.

The automatic controller 20 is used to control the start and close of each valve in the device.

[0024] The automatic air-controlled horseradish extract liquid filter purifier A is moved by a bracket 21 with moving wheels 22 provided at the bottom.

[0025] like Figure 1As shown, the automatic horseradish extract room temperature smoke fumigator and fresh air conveyor B includes a powerful air supply component a, a room temperature smoke spray component b, a fresh air temperature and humidity adjustment component c, a horseradish extract liquid tank d, an automatic controller 2 e, a direction control component f, and a machine moving component g.

[0028] In the mobile device for disinfecting and refreshing air using a horseradish extract aqueous emulsion, an air hood 1 is the outer cover of the machine and has a porous or mesh structure. Polluted air enters through the porous or mesh structure of the air hood 1. An air pump 2, which powerfully draws polluted air from the enclosed space during fresh air exchange, exhausts the air carrying the horseradish extract after the horseradish extract undergoes room-temperature fumigation disinfection. A mist leaching nozzle 3, which kills pathogens carried in the polluted air drawn in through the air inlet channel, is leached by the horseradish extract mist sprayed from the mist leaching nozzle 3. An air barrier grating 4, which comprises a multi-layer fine mesh or a 0.2-1 mm diameter pore sheet, is installed above the mist leaching nozzle at the front end of the air inlet channel to form a disinfection and sterilization channel, hindering the smooth passage of polluted air and ensuring that it is exposed to as much horseradish extract as possible during passage. Disinfection and sterilization chamber 5: After being sprayed with horseradish solution, contaminated air enters the horseradish solution in aqueous emulsion and then passes through a powerful water-vapor mixing plate 6. The densely packed pores (0.2-1 mm in diameter) on the powerful water-vapor mixing plate 6 prevent the contaminated air from passing through smoothly, dispersing large bubbles in the horseradish solution into tiny bubbles and maximizing contact between the horseradish and airborne pathogens. To enhance the sterilization effect, the number of mist-leaching nozzles 3, air-blocking grids 4, and powerful water-vapor mixing plates 6 can be increased. To save manufacturing costs and reduce the size and weight of the automatic air-controlled horseradish solution filter-purifier A, the number of mist-leaching nozzles, air-blocking grids, and powerful water-vapor mixing plates can be reduced by increasing the concentration of the horseradish solution in aqueous emulsion. Air outlet 7: This is the outlet for the sterilized air, through which the sterilized, filtered air passing through the final layer of the powerful water-vapor mixing plate is discharged. A sterilized air outlet pipe 8: This is connected to the air outlet 7 and is used to connect to an exhaust extension duct. Water inlet pipe 9: This pipe connects to the tap water input, used to inject clean water into the automatic air-controlled horseradish extract solution filter-purifier A during operation. Automatic water inlet valve 10: Connects to the tap water pipe and automatically controls the injection of clean water as needed. Water level indicator tube 11: Connects to the bottom of the disinfection and sterilization chamber and displays the water level of the horseradish extract solution during operation of the automatic air-controlled horseradish extract solution filter-purifier A. Horseradish extract indicator tube 12: Its upper and lower ends are connected to the horseradish extract storage tank and the horseradish extract automatic valve, respectively, to indicate the amount of horseradish extract aqueous emulsion being used for disinfection and sterilization. Horseradish extract automatic valve 13: Its upper end is connected to the horseradish extract indicator tube 12, and its lower end is connected to the water level indicator tube 11 or directly to the disinfection and sterilization chamber 5, allowing for automatic addition of the required horseradish extract aqueous emulsion. Horseradish extract storage tank 14: Connects to the horseradish extract indicator tube 12 and stores the horseradish extract aqueous emulsion product. Spray pressure pump 15: Its water inlet is connected to the bottom of the sterilization chamber, and its outlet is connected to a pipe connected to the mist leaching nozzle. It pressurizes the horseradish solution and delivers it to the mist leaching nozzle, spraying the polluted air. Spray liquid one-way return valve 16: Pumps the leached and settled horseradish solution back into the sterilization chamber.Waste liquid drain valve 17: Its water inlet is connected to the bottom of the disinfection and sterilization chamber. After the horseradish extract solution has been used for a certain period of time, it automatically drains the waste liquid from the automatic air-controlled horseradish extract solution filter-purifier A before replacing the solution. Sound insulation and noise reduction layer 18: This layer covers the entire exterior surface of the automatic air-controlled horseradish extract solution filter-purifier A, excluding the air hood, water level indicator tube, and horseradish extract indicator tube, which must be exposed. It is used to reduce or eliminate the noise generated by polluted air passing through the air barrier fence, powerful water-gas mixing plate, and related components during operation of the automatic air-controlled horseradish extract solution filter-purifier A. Residual horseradish extract gas discharge control valve 19: Its air inlet is connected to the front section of the air inlet channel, and its air outlet is connected to the disinfected air outlet pipe. It works in conjunction with the exhaust pump 2 to control the discharge of air with a horseradish extract odor after the horseradish extract aqueous emulsion solution is sterilized by room-temperature fumigation. Automatic controller 20: Automatically controls the metered addition of horseradish extract aqueous emulsion, the metered addition of clean water, system startup, and waste liquid discharge according to system operating requirements. This allows for the linkage between the automatic horseradish extract air filter-purifier A, the automatic horseradish extract room-temperature fumigation disinfector, and the fresh air conveyor B, or the automatic horseradish extract air filter-purifier A and the clean fresh air generator C, or the automatic horseradish extract air filter-purifier A, the automatic horseradish extract room-temperature fumigation disinfector, the fresh air conveyor B, and the clean fresh air generator C. Bracket 21 and movable wheels 22: facilitate the movement and use of the automatic horseradish extract air filter-purifier A.

[0029] The mobile device for disinfecting and sterilizing horseradish extract with aqueous emulsion and replacing fresh air of the present invention comprises the following components: a strong air supply component a is used to accelerate the diffusion of horseradish extract smoke at room temperature in a confined space during horseradish extract disinfection and sterilization; a stirrer is used to agitate the air in the confined space after the horseradish extract disinfection and sterilization, so that all the air with residual horseradish extract odor is sucked out as soon as possible; a stirrer is used to agitate the air in the confined space when replacing fresh air, so that the polluted air can be sucked out at any time as much as possible; a normal temperature smoke spray component b is used to convert the horseradish extract aqueous emulsion solution into 20-50 micron normal temperature smoke particles, which are evenly diffused by the strong air supply component; and a fresh air temperature and humidity adjustment component c is used to adjust the input fresh air according to the demand. To adjust temperature and humidity, this function can also be integrated into the clean fresh air generator C. The horseradish extract tank D is connected to the ambient temperature fog spray assembly and stores the horseradish extract aqueous emulsion solution. Automatic controller II e automatically controls ambient temperature fog release, forced air flow, temperature and humidity, and system on / off, achieving linkage with the automatic air-controlled horseradish extract liquid filter purifier A and the clean fresh air generator C. The direction control component f controls the forced air flow in any horizontal and vertical direction as needed to optimize device functionality. The machine movement component g facilitates the mobility of the automatic horseradish extract ambient temperature fog fumigator and fresh air conveyor B. The clean fresh air generator C can utilize air conditioning as a source of fresh air at a specific temperature and humidity. This can utilize existing ventilation and air supply equipment or be redesigned and manufactured based on actual needs.

[0030] According to the biological fumigant horseradish extract, the efficient and broad spectrum horseradish extract is almost all had to killing activity to all organisms, can effectively kill the unknown pathogenic microorganisms known now and that may newly occur in the future, its biologically active component is the mustard effective component, and the general about 72 hours of lasting effect period is nontoxic, harmless, pollution-free to personnel and environment, can replace a lot of chemical disinfectants and the disinfection and epidemic prevention technology that has been used fully. Because the horseradish extract biological activity is high, it is very strong to mucous membrane irritation, has very strong pungent odor, and the concentration of horseradish extract in the air does not allow to exceed people's perception concentration when personnel are active. So the present invention avoids horseradish extract from directly contacting the people, by " automatic air horseradish extract liquid filtration purifier " will contain various pathogens (microorganisms), the air that comprises potential epidemic situation pathogens and dust particles is concentrated by continuous suction of an air pump, after the multi-stage leaching of horseradish extract aqueous emulsion solution, purify, by the strong water vapor mixing plate repeatedly the air after the leaching and the horseradish extract aqueous emulsion solution are fully contacted and mixed again, guarantee that all pathogens in the air are thoroughly killed. After killing germs, the air, carrying the smell of horseradish, is discharged through the disinfection air outlet and dissipated in the air away from human activity. When no one is around, the "automatic horseradish room-temperature smoke fumigation disinfection and fresh air conveyor" disperses the horseradish water emulsion solution into 20-50 micron drug particles, which diffuse into the confined space. This long-term fumigation kills various pathogens in the air and on surfaces. Before anyone enters, the air with the residual horseradish smell is discharged through the powerful air supply assembly a and the residual horseradish gas discharge control valve 19, without affecting the normal activities of personnel after disinfection. Using water as the treatment medium, the water emulsion is a very suitable dosage form. The inventors have demonstrated through testing various horseradish dosage forms that the water emulsion easily and evenly disperses in water and is relatively stable. Its effectiveness in killing various pathogenic microorganisms and small pests by using room-temperature smoke spray fumigation in protected horticultural spaces has been fully recognized and has been widely promoted and applied. The water emulsion is safe and convenient to store, transport, and use.

[0031] Drawing on the experience of Beijing in promoting the use of 1L of 20% horseradish extract emulsion (1L of 20% horseradish extract emulsion is equivalent to 200g of effective horseradish extract, equivalent to 200ml of 100% horseradish extract emulsion) in a 1000L vegetable greenhouse, fumigation and disinfection using room-temperature smoke spraying, followed by sealing for 4-12 hours, can completely kill various fungi, bacteria, and small pests in the greenhouse. Based on the inventor's more than 10 years of testing and application verification using horseradish extract to control agricultural pests, the horseradish extract dosage per unit volume for killing various pests is ranked from highest to lowest: weeds > insects > nematodes > fungi > bacteria > viruses. Generally, a dosage of less than 1 part per million can decompose viruses, less than 2 parts per million can kill common bacteria, less than 5 parts per million can kill common fungi, less than 1 part per hundred thousand can kill various pathogenic nematodes, and less than 2 parts per hundred thousand can kill various small pests. Therefore, using horseradish extract in water emulsion at a concentration of 0.1-1 mg / L can completely kill various human infectious pathogens such as influenza virus and E. coli.

[0032] The mobile device for disinfecting, sterilizing and replacing fresh air with horseradish emulsion of the present invention can be used in the following situations:

[0033] 1. Disinfection and sterilization in unmanned state

[0034] In an unmanned state, horseradish extract emulsion is used for disinfection and sterilization. According to the size of the disinfection and sterilization space, 20% horseradish extract emulsion is measured at 0.1-1 mg / L and put into the horseradish extract liquid tank. An appropriate amount of clean water is added, and the power is turned on. The normal temperature smoke spray component is started by the automatic controller 2 to start releasing horseradish extract emulsion smoke particles with a size of 20-50 microns. The horseradish extract smoke is evenly diffused in the closed space with the help of the strong air supply component and the direction control component. After the liquid is sprayed, the automatic horseradish extract normal temperature smoke fumigation disinfector and the fresh air conveyor B are automatically stopped. The closed fumigation disinfection time is negatively correlated with the amount of horseradish used. The higher the amount per unit volume, the shorter the fumigation disinfection time. The closed fumigation can be performed for 0.5-12 hours according to actual conditions. If you can wait for 12 hours, 20% horseradish water emulsion can be measured at 0.1 ml / L. If you can only wait for 0.5 hours, 20% horseradish water emulsion needs to be measured at 1 ml / L, and so on. After all kinds of pathogens exposed to the air and on the surface of objects are completely killed, the automatic controller 1 and the automatic controller 2 jointly control the powerful air supply component, the exhaust pump and the residual horseradish gas emission control valve to quickly suck out the disinfected air with the smell of horseradish.

[0035] 2. When there are people moving around, fresh air should be replaced at any time, and the fresh air should be natural wind.

[0036] Based on the concentration of the prepared horseradish solution that can kill pathogens and the amount of solution to be prepared (the solution level must be at least one layer above the strong water-air mixing plate), automatic controller 1 controls the horseradish automatic valve and automatic water inlet valve to add the horseradish water emulsion and clean water in proportion into the disinfection and sterilization chamber (air inlet channel) of automatic air horseradish liquid filter purifier A. Automatic controller 1 also controls the vacuum pump, spray pressure pump, and spray liquid one-way reflux valve to operate simultaneously. Contaminated air is pressurized by a suction pump at the air inlet. It then passes through the front section of the air channel, where it is sprayed with horseradish solution several times and blocked by air barrier grilles. This allows the airborne pathogens and dust to be leached and washed into the horseradish solution as much as possible. The leached air then enters the horseradish solution along the front section of the air channel. However, it encounters a strong water-vapor mixing plate, where it is blocked by pressure and forced to squeeze through the densely packed holes. This disperses the air into tiny bubbles that mix with the horseradish solution, ensuring full contact with the horseradish solution and completely killing any remaining pathogens and dust. The sterilized air is then discharged through the sterilized air outlet. Because it may carry traces of horseradish odor, it is discharged to a higher altitude or a distant location through the sterilized air outlet pipe if necessary.

[0037] 3. Change fresh air at any time when there are people moving around

[0038] According to the needs, the automatic controller coordinates and controls the automatic air horseradish extract liquid filter purifier A, the automatic horseradish extract normal temperature smoke fumigator and fresh air conveyor B, and the clean fresh air generator C. (1) Replace the natural fresh air at any time: When the automatic air horseradish extract liquid filter purifier A is working, the automatic horseradish extract normal temperature smoke fumigator and fresh air conveyor B are placed in appropriate positions to keep the natural air supply from the outside unobstructed, coordinate and control the powerful air supply components and direction control components of the automatic horseradish extract normal temperature smoke fumigator and fresh air conveyor B to work, automatically change the air supply angle in the horizontal and vertical directions, and continuously stir the air so that the polluted air in the room can be sucked out at any time and replaced with fresh air from the outside. (2) Replace constant temperature and constant humidity clean fresh air at any time: When the automatic air horseradish extract liquid filter purifier A is working, a constant temperature (constant humidity) clean air source is provided through the clean fresh air generator C, and the powerful blower and direction control components of the automatic horseradish extract normal temperature smoke fumigator and the fresh air conveyor B are controlled to work, and the air is continuously stirred to maintain a clean constant temperature (constant humidity) environment for the indoor air; or the clean fresh air generator C is used as a clean air source to control the fresh air heating and humidification components of the automatic horseradish extract normal temperature smoke fumigator and the fresh air conveyor B, so that the normal temperature smoke machine sprays water mist for humidification and the electric heater heats and increases the temperature, and the temperature and humidity sensor and the powerful blower and direction control components are used to continuously stir the air to maintain the constant temperature, humidity and cleanliness of the indoor air.

[0039] Assuming that a 1000L room that has been used for patient isolation is to be disinfected and sterilized, 0.5-5L (1L) of 20% horseradish emulsion in water is used at a dosage of 0.1-1mg / L for disinfection of a 1000L room. (20% horseradish extract emulsion is equivalent to 200g of horseradish extract effective dose, which is equivalent to 200ml of 100% horseradish extract emulsion.) Assuming that 1L of the 20% horseradish extract emulsion is added to the horseradish extract solution tank of the automatic horseradish extract normal temperature smoke fumigator and fresh air conveyor B, 2-5L of clean water is added (the normal temperature smoke solution only releases the agent, and the amount of water added does not affect the effectiveness of killing pathogens and pests. Adding more water extends the time for releasing the smoke, while adding less water shortens the time for releasing the smoke.) The automatic controller of the automatic horseradish extract normal temperature smoke fumigator and fresh air conveyor B activates the normal temperature smoke spray and the powerful air supply component, which begins to rapidly release horseradish extract smoke particles of 20-50 microns in size. The automatic controller controls the direction control component to cause the normal temperature smoke to stir the air in different directions, ensuring that every corner is filled with horseradish extract smoke particles. Maintain closed fumigation for 0.5-12 hours according to actual conditions, and automatically control the suction and discharge of air with horseradish odor before people enter.

[0040] Assume that fresh air is being replaced in a gathering place: according to the size of the place and the number of people, one or more sets of automatic air control horseradish liquid filter purifier A are selected to ensure timely replacement of polluted air in the place. Generally, it only takes 0.5×10 -6 -2×10 -6 The effective concentration of horseradish (the maximum fungal killing concentration is no more than 5×10 -6 ). According to the volume of the disinfection and sterilization chamber of the automatic air horseradish extract liquid filter purifier A and the desired strictness of disinfection and sterilization, determine the concentration of the horseradish extract water emulsion solution and the amount of solution to be prepared. Enter the concentration of the solution in parts per million and the total amount of solution (or the required amount of horseradish extract water emulsion and clean water) through the automatic controller panel. The horseradish extract automatic valve and the automatic water inlet valve will automatically control the addition of horseradish extract water emulsion and clean water. After the whole machine is started, it will start to use the horseradish extract water emulsion solution to disinfect, sterilize and filter the sucked contaminated air. For example, a small automatic air horseradish extract liquid filter purifier A suitable for ordinary households can prepare 5-10L of horseradish extract water emulsion solution (it can actually be reduced). For activity venues with more people, a larger automatic air horseradish extract liquid filter purifier A can be used to prepare 50-100L of horseradish extract water emulsion solution. In order to ensure that all kinds of pathogens are completely killed, increase the amount of horseradish extract water emulsion used, according to 20×10 -6To prepare 5-10L of solution at an effective concentration, add 0.5ml-1ml of 20% horseradish extract in water; to prepare 50-100L of solution, add 5ml-10ml of 20% horseradish extract in water. The disinfectant solution replacement schedule is based on the typical 72-hour duration of horseradish extract in water. In practice, the horseradish extract wastewater can be drained through the waste drain valve within 72 hours, followed by re-addition of horseradish extract in water and clean water to maintain the appropriate concentration for thorough disinfection and sterilization.

[0041] In order to suck out the contaminated air as much as possible at any time, avoid objects in corners or spaces that hinder the smooth suction of contaminated air, and prevent germs and dust from being retained in local spaces, the automatic controller of the automatic horseradish root room temperature smoke fumigator and the fresh air conveyor B controls the powerful blower and the direction control component to work together, continuously direct or change direction to supply strong air, and continuously stir the air to ensure that the contaminated air is sucked out at any time.

[0042] In summary, this device has very important practical significance for the prevention and control of various epidemics. It is suitable for all kinds of places and is easy to promote and apply. It will play a very important role in the construction of my country's biosafety prevention and control system.
