The present invention relates to a vehicle disinfection system and a vehicle disinfection method using the same.

Despite technological advances, the livestock industry has suffered enormous damage due to periodic foot-and-mouth disease and AI (Avian Influenza).

In the past three years, the number of dead fishes in 2014 is estimated to be 20,000 · AI 14.49 million, and in 2015, 140,000 · AI · 486 million, · 20,206 · 200,600 · AI Respectively.

Analysis of the spread of foot-and-mouth disease and AI shows that livestock-related vehicles account for a larger share than wildlife. In 2015, the 'Big Data Seminar on Agriculture' hosted by the Institute of Neo-Confucius, analyzed the operation records of livestock-related vehicles equipped with vehicle driving recorders, and found that the transmission of livestock communicable diseases due to livestock-related vehicles was close to 70% .

Considering such research data, it is necessary to develop a disinfection system for livestock-related vehicles in order to reduce the damage caused by the livestock industry.

In particular, in case of disinfection using a disinfection system for a vehicle, the disinfectant is sprayed for about 2 to 5 minutes. It is difficult to expect sufficient disinfection efficacy by simply spraying the disinfectant for about 2 to 5 minutes because of short contact time.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may obscure the subject matter of the present invention.

When an animal disease such as foot-and-mouth disease or AI (Avian Influenza) occurs, a sanitary organization such as the Agriculture, Forestry and Livestock Quarantine Headquarters will take steps to prevent the spread of the livestock epidemic.

In particular, it will establish a rapid disinfection system for livestock-related vehicles (for example, feed carcasses, manure cars, livestock transport vehicles), which is one of the major causes of the spread of livestock infectious diseases.

The sanitary and sanitary control system determines the main sites for the outbreaks in the area where the livestock epidemic has occurred, and establishes a disinfection system for the vehicles at the relevant sites.

That is, livestock-related vehicles (or all vehicles) that pass through the area where the livestock epidemic has occurred pass through the vehicle disinfection system. At this time, the disinfecting liquid is sprayed to the vehicle passing through the disinfecting system for the vehicle.

In order to achieve complete disinfection, the disinfection process of the vehicle must be performed in sufficient time in the disinfection system for the vehicle.

However, considering that there are a large number of vehicles to be disinfected, the disinfection process may cause traffic congestion, which may cause discomfort to the general public.

In order to perform the disinfection in such a limited time, the disinfection efficiency can not be improved. The most direct way to improve disinfection efficiency is to increase the concentration of the disinfectant solution, but a high concentration of the disinfectant solution may pollute the environment or be harmful to the human body.

Accordingly, it is an object of the present invention to provide a vehicle disinfection system capable of improving the disinfection efficiency and a vehicle disinfection method using the same.

Disinfection system for vehicles

FIG. 1 is a schematic perspective view of a disinfecting system for a vehicle according to an embodiment of the present invention, and FIG. 2 is a schematic exploded perspective view of a disinfecting housing of a disinfecting system for a vehicle according to an embodiment of the present invention. 3 is a schematic block diagram for explaining each configuration of the automotive disinfection system of the present invention and its connection relationship.

1 to 3, a car disinfection system according to an example of the present invention will be described.

The disinfecting system for a vehicle according to an embodiment of the present invention includes a disinfection housing 10 having a space 20 in which a disinfection of the vehicle C can be performed.

During the course of disinfection being performed, the vehicle C passes through the space 20 of the disinfection housing 10 manually or automatically by the driver or by the driver. However, the present invention is not limited thereto, and it is also possible that the structures of the present invention move while the vehicle C is stationary to perform disinfection.

However, for clarity of explanation, it is assumed that the disinfection process is performed while the vehicle C passes through the space portion 20. [

In the disinfecting system for a vehicle according to an example of the present invention, a plurality of sensors 50 may be installed on the floor in order to confirm the position of the vehicle C. The sensor 50 may be in a manner that senses pressure, but is not limited thereto.

The vehicle C entering the disinfecting system for a vehicle according to an embodiment of the present invention first enters the preliminary washing section.

The vehicle having passed through the preliminary washing section enters the space portion 20 of the housing 10 where sterilization is performed. An air shutter using high-pressure wind may be installed at the entrance and the exit of the space 20, but the present invention is not limited thereto.

A sensor 50 is disposed at the bottom portion 12 of the disinfecting housing 10 at regular intervals to control the disinfection system according to the position of the vehicle C. [

The disinfection housing 10 of the disinfecting system for a vehicle according to an embodiment of the present invention includes a preliminary washing unit 100 and a disinfection unit 200. Further, as will be described later, the outlet cleaning unit 300 may further be included. The disinfecting housing 10 includes a machine room 400 in which a tank or a disinfectant manufacturing device for storing a washing solution or a disinfectant is installed, and a disinfection room 500 in which disinfection is performed for a person getting off the vehicle.

First, referring to the preliminary washing unit 100, the preliminary washing unit 100 performs a role of cleaning the surface of the vehicle (C, a disinfection target vehicle) entering the disinfection housing 10 and a role of preheating.

In the case of livestock vehicles, livestock manure is often attached to the wheels or floor of the vehicle, and the livestock manure is dried and attached strongly to the surface of the vehicle while the vehicle is moving to the base where the disinfection system is built. If the livestock manure is attached to the vehicle, the livestock manure itself becomes a propagation medium of the livestock infectious disease, or the attached livestock manure acts as a film which interrupts the disinfection process.

The disinfecting system for a vehicle according to an embodiment of the present invention is a system that disinfects foreign matter such as livestock manure adhering to a vehicle C by spraying washing water in the preliminary washing unit 100 to prevent the removal and disinfection of livestock manure And remove it. In particular, the disinfecting system for a vehicle according to an embodiment of the present invention can perform cleaning on the wheels, the lower portion, the side surface, and the upper surface of the vehicle C in the preliminary cleaning portion 100.

In addition, the pre-cleaning unit 100 of the present invention preheats the surface of the vehicle C, which is to maximize the disinfection efficiency in the process of disinfection as described later. In addition, a separate structure is provided to increase the temperature of the washing liquid, thereby making it easier to remove foreign matter such as dried livestock manure. At this time, the cleaning liquid injected from the pre-cleaning unit 100 of the present invention has a temperature higher than the room temperature (25 ° C), and preferably a temperature of 50 ° C or higher.

The preliminary washing unit 100 includes a preliminary washing unit tank 110 and a preliminary washing unit 110. The preliminary washing unit 100 accommodates the washing liquid for preheating the surface of the entering vehicle, And a preliminary cleaner nozzle 120 connected to the tank 110 for spraying the heated cleaning liquid to the vehicle at a high pressure. At this time, the preliminary washing unit tank 110 may be installed in the machine room 400.

The preliminary washing section tank 110 may include a heating means for heating the washing liquid, for example, a heating coil. On the other hand, the cleaning liquid can be injected by the pump into the preliminary cleaning nozzle 120.

The preliminary cleaning nozzle 120 may be installed on the side surface 11 of the disinfecting housing 10 and may include a position where the lower end of the vehicle or the wheel can be cleaned and a front surface and a top surface of the vehicle, A plurality of the cleaning units may be disposed at positions where the cleaning units can be cleaned.

Particularly, in the disinfecting system for a vehicle according to an embodiment of the present invention, the nozzles 120, 220, and 320 described later can be disposed on the ceiling 13 of the housing 10 to perform washing and disinfection on the upper surface of the vehicle.

The washing solution may be water, but it is not limited thereto, and it is also possible to use a disinfecting solution if necessary.

A full disinfection process is performed on the vehicle C in which the preliminary cleaning has been performed. That is, the disinfecting performance unit 200 injects a high-temperature disinfectant to the preheated vehicle. At this time, the washing liquid sprayed from the disinfecting performance unit 200 of the present invention has a temperature higher than room temperature (25 ° C), preferably 65 ° C or higher.

At this time, the disinfectant used in the present invention may contain hypochlorous acid, hypochlorous acid and OH radical.

The disinfecting system for a vehicle according to an embodiment of the present invention is characterized by using a high-temperature disinfectant to increase disinfection efficiency without increasing the disinfecting time or increasing the concentration of the disinfecting water.

In order to confirm the disinfection efficiency according to the temperature of the disinfectant solution, an experiment was generally carried out as follows.

In order to evaluate the virulence effect of the disinfectant composition prepared according to one embodiment of the present invention, low-pathogenic avian influenza virus (LPAI virus) and foot-and-mouth disease virus (FMD virus) are used. At this time, the LPAI virus is evaluated using developmental cells, and the FMD virus is evaluated using a cell line.

The diluent is a medium suitable for selected cell proliferation and related reagents. The dilution of water-in-water dilution and the dilution of organic substance shall be in accordance with the test method for bacteria. However, 5% fetal bovine serum is used instead of the yeast extract for the organic diluent.

The neutralization medium is a chemical component of the disinfectant. The neutralization medium is a medium containing 10% fetal bovine serum that is immobilized on a medium suitable for the used cells.

The viral strain was inoculated into the umbilical cord of a 10-day-old Avian Influenza Virus (SPF) non-antibody SPF (Specific Pathogen Free) developmental flora, and subcultured. The viral load of the proliferated virus was maximized (virus titer 10 ⁷ EID ₅₀ / mL Or more).

For the disinfectant used in the test, prepare a disinfectant dilution with the dilution concentration before the reaction with the test solution.

After mixing 1.0 ml of the viral virus solution with 19.0 ml of the above disinfectant diluent, 2.5 ml of the mixture is taken at intervals of 1 minute, placed in a test tube containing the same amount of disinfectant diluent, reacted for 30 minutes at each temperature Mix them every 10 minutes on the way.

Once the reaction between the disinfectant and the pathogen has been completed, 1.0 ml of the disinfectant is immediately taken out to neutralize the efficacy of the disinfectant, placed in a neutralizing medium of the same amount at 37 ° C, mixed and the virus content is measured by inoculating the appropriate amount into the cell or developmental cell.

In general, microplate titration or plaque assay method is used for the degree of loss of infectivity of virus. In the test using the developmental cell, 0.2 ml of each of the 5 developmental cells per dilution is inoculated into the allantoic cavity, incubated for 5 days in a 37 ° C. incubator, and examined every day for virus multiplication.

The pathogen control should be tested with no disinfectant under light water conditions and the toxicity of the pathogen should be confirmed to be 2 × 10 ⁵ TCID ₅₀ per ㎖ in the neutralization reaction stage and cytotoxicity by the disinfectant in the toxic control group Make sure it did not happen.

The virus content calculation uses the Karber method.

In the present invention, in order to confirm the effect of the temperature of the disinfectant, experiments were conducted at 55 ° C and 65 ° C, respectively, and the results are shown in Tables 1 and 2 below.

Table 1 shows the experimental results of the control group treated with light water at 4 ° C instead of the disinfectant solution. In Table 2, Sample A, Sample B, Sample C, and Sample D were experiments containing only the virus as an experimental solution containing no hypochlorous acid. Samples A ', B', C 'and D' As a disinfectant solution. In Table 2, the temperature means the temperature of the test solution. The decrease in the activity means a change in the activity of a sample containing hypochlorous acid based on a sample containing only a virus.

In this experiment, the effect of disinfection temperature and time on disinfection efficiency was examined by using temperature and time as disinfection variables.

Comparing Sample A 'with Sample B', no significant change in activity was observed at a temperature of 55 ° C even when the disinfection time was increased. However, when comparing Sample A 'with Sample C', it can be seen that Sample C 'has a higher titer reduction, even though the disinfection time is reduced. Further, when comparing the sample A 'and the sample D' having the same disinfecting time, it can be seen that the decrease in the drug price is remarkably increased due to the increase in the temperature of the disinfecting liquid.

In other words, it is most effective to increase the temperature of the disinfectant solution in order to improve the disinfection efficiency within a limited time. In particular, the highest disinfection efficiency can be secured by performing the disinfection solution at a temperature of 65 ° C or higher and a disinfecting time of 3 minutes or longer.

However, even if the temperature of the disinfectant is increased to 65 ° C or higher, spraying the disinfectant on the actual vehicle does not show the expected disinfection efficiency during the experiment because the surface temperature of the vehicle is low. Particularly in winter, the temperature of the surface of the vehicle is too low, so that even if a high temperature disinfectant is sprayed, the temperature of the disinfectant drops significantly on the surface of the actual vehicle. If the temperature of the disinfectant solution is remarkably increased more than 70 ° C in order to solve this problem, it is difficult to expect a desired disinfecting effect due to the decomposition of the disinfectant solution by heat. Therefore, it is necessary to perform the disinfection at a temperature at which the temperature of the disinfectant is raised to a temperature at which the decomposition phenomenon of the disinfectant does not occur, but the disinfection effect is maximized.

In order to solve such a problem, the disinfecting system for a vehicle according to an embodiment of the present invention has a preliminary washing unit 100. That is, the surface of the vehicle C entering the disinfection housing 10 in the preliminary cleaner 100 is preheated by the disinfectant to sufficiently increase the surface temperature of the vehicle. In the disinfection unit 200, It was possible to obtain sufficient disinfection efficiency even in a non-laboratory.

On the other hand, it is very important to perform disinfection by raising the temperature of the disinfectant to a high temperature (for example, 65 ° C or more) as described above. Disinfection of more than 2 minutes, preferably more than 3 minutes is carried out in one vehicle, and a lot of disinfectant is consumed in the disinfection process. That is, once the disinfection is performed on one vehicle, it is necessary to supplement the disinfectant solution. The temperature of the disinfectant solution to be newly replenished is low, and the temperature of the disinfectant solution in the tank is lowered as a whole due to the disinfectant solution supplemented.

The disinfection unit 200 according to an exemplary embodiment of the present invention includes a disinfecting performer tank 210 and a disinfecting performer tank 210 that can receive and heat the disinfectant capable of performing disinfection on the preheated vehicle, In order to prevent the temperature of the disinfectant from being reduced by supplementing the disinfection water, the disinfecting performer tank 210 receives the unheated disinfectant liquid, And a secondary tank 212 in which the heated disinfectant flows into the heated primary tank 211 and the primary tank 211 and is reheated. Disinfecting performer tanks 210 may be disposed in the machine room 400 similar to the pre-cleaner tanks 110 and the disinfecting performer nozzles 220 may be installed on the side portions 11 of the disinfecting housing 10 , And a plurality of positions at which the entire surface of the vehicle can be cleaned, including a position where the bottom of the vehicle or the position where the wheels can be cleaned can be cleaned.

The disinfectant is heated to a predetermined temperature in the primary tank 211 and then supplied to the secondary tank 212. The high temperature disinfectant contained in the secondary tank 212 is supplied to the vehicle C ) To perform disinfection.

In the automotive disinfecting system of the present invention, the disinfectant may be a disinfectant prepared elsewhere, but it may be provided in the automotive disinfecting system. At this time, the disinfectant producing apparatus 1000 may be installed in the machine room 400.

The disinfectant used in the automotive disinfecting system of the present invention may contain hypochlorous acid and may contain hypochlorous acid and OH radical for improving the disinfection efficiency. However, OH radicals have a short remaining time and can not be transported or used anywhere else.

Accordingly, the disinfection efficiency of the automotive disinfection system is improved by providing a disinfection liquid production apparatus 1000 including an OH radical generator together with a hypochlorous acid (HOCl) generator.

4 is a block diagram briefly showing the connection relationship of each component of the disinfectant producing apparatus 1000. As shown in FIG.

4 is a block diagram briefly showing the connection relationship of each component of the disinfectant producing apparatus 1000. As shown in FIG.

 Referring to FIG. 4, the disinfectant producing apparatus 1000 includes a hypochlorous acid generator 1100 and an OH radical generator 1200.

First, the hypochlorous acid generator 1100 includes a first reaction tank 1110.

The first reaction vessel 1110 is provided with a first oxidation electrode 1111 and a first reduction electrode 1112. At this time, the first oxidizing electrode 1111 and the first reducing electrode 1112 constitute an electrolysis cell electrode reacting unit.

The disinfecting system for a vehicle according to an embodiment of the present invention generates a hypochlorous acid through electrolysis by applying a current to the first oxidizing electrode 1111 and the first reducing electrode 1112 to the power supply 1800. [

In particular, in order to increase the efficiency of hypochlorous acid generation, the first oxidation electrode 1111 is formed by coating ruthenium-iridium on titanium, and the first reducing electrode 1112 is formed of titanium .

The first tank 1310, the second tank 1320 and the third tank 1330 for supplying the raw materials necessary for the production of hypochlorous acid or OH radical to the first reaction tank 1110 and the second reaction tank 1210, .

The first tank 1310 may serve to supply the electrolytic solution to the first reaction tank 1110. In the present invention, an aqueous solution of HCl was used as an electrolytic solution. The electrolytic solution becomes the main raw material for producing hypochlorous acid.

The second tank 1320 serves to supply raw water to the first reaction tank 1110 or the second reaction tank 1210.

The third tank 1330 serves to supply the electrolyte to the first reaction tank 1110 or the second reaction tank 1210. The electrolyte plays a role in regulating electrical conductivity when electrolysis is performed. In the present invention, NaCl was used as an electrolyte. However, it is important to adjust the amount of sodium hypochlorite (NaOCl) other than hypochlorous acid (HOCl) generated in the first reaction tank 1110 when NaCl is added in too much amount.

The electrolyte solution is allowed to flow into the lower end portion of the electrolytic cell electrode reaction portion where the first oxidation electrode 1111 and the first reducing electrode 1112 are located.

After the raw material is supplied from each tank, a current is applied to the first oxidation electrode 1111 and the second reduction electrode 1112 from the power source unit 1800.

Hypochlorous acid is produced at the lower end of the electrolytic cell electrode reaction part through the following reaction.

At this time, the pH of the first reaction tank 1110 is maintained at 4.5 to 6.5, thereby inducing hypochlorous acid to be generated without generating sodium hypochlorite or toxic chlorine gas.

The first oxidation electrode 1111 operates as an anode in the electrolysis, and the reaction occurring in the first oxidation electrode 1111 is as follows.

Hypochlorous acid is produced in the first reaction vessel 1110 through the above reaction occurring in the first oxidation electrode 1111 and the first reduction electrode 1112.

In the meantime, it can be seen that OH radicals are generated in the first reaction chamber 1110, but the amount of OH radicals generated in the first reaction chamber 1110 is very small and the remaining time is short, There is little contribution to improvement of disinfection ability.

Accordingly, in order to substantially contribute to the improvement of the disinfection ability of the vehicle disinfection system, the present invention includes an OH radical generator 1200 capable of generating OH radicals at the site where the actual disinfection is performed, in addition to hypochlorous acid have. That is, the present invention includes the OH radical generator 1200, which is separate from the hypochlorous acid generator 1100, so that the remaining time can be increased by increasing the amount of generated OH radicals.

First, the OH radical generator 1200 has a second reaction tank 1210.

The second reaction tank 1210 is provided with a second oxidation electrode 1211 and a second reduction electrode 1212.

The disinfectant producing apparatus 1000 of the disinfecting system for a vehicle according to an embodiment of the present invention applies current to the second oxidizing electrode 1211 and the second reducing electrode 1212 to the power source 1800, The OH radical is produced by the reaction.

H ₂ O → OH + e ^- + H ⁺

That is, the automotive disinfection system according to an embodiment of the present invention generates OH radicals on the field, and generates OH radicals that are significantly larger than OH radicals generated with hypochlorous acid, and OH radicals are used .

In order to increase the remaining time of the OH radical, the amount of the generated OH radical must be significantly increased. Therefore, in order to further increase the remaining time of the OH radical, the automotive disinfecting system according to an embodiment of the present invention includes a second oxidizing electrode 1211 And the second reducing electrode 1212 may be formed of a boron doped diamond (BDD) electrode.

Boron-doped diamond is superior in durability due to its high anodic stability in both water-soluble electrolytes and non-water-soluble electrolytes. In addition, boron-doped diamond is resistant to corrosion and has the advantage of having a large potential window.

In particular, when an anode is formed with boron-doped diamond, OH radicals are produced directly through electrolysis with very high current efficiency.

The present invention is capable of disinfecting the vehicle by ejecting hypochlorous acid and OH radicals generated in the hypochlorous acid generator 1100 and the OH radical generator 1200 to the disinfecting performing nozzle 220 by a pump or the like.

The vehicle disinfecting method according to another embodiment of the present invention can use a disinfecting system for a vehicle having a preliminary washing unit and a disinfecting performing unit. In more detail, the method for disinfecting a vehicle according to another embodiment of the present invention includes the steps of S110 entering a vehicle to be disinfected by a disinfecting system for a vehicle, spraying a cleaning liquid on the disinfected vehicle, (S 120) of sterilizing the surface of the disinfection target vehicle (S 120), and disinfecting the disinfected target vehicle by spraying a high-temperature disinfectant to the pre-heated disinfection target vehicle (S 130).

First, in step S110, the vehicle to be disinfected is entered into the disinfecting system for the vehicle. At this time, the persons on board the vehicle can get off the vehicle, enter the public sanitary room, and disinfect the person.

In the case of the vehicle entering the automotive disinfection system, a step of cleaning and preheating the surface of the vehicle to be sterilized (S120) is performed by spraying the cleaning liquid on the vehicle to be disinfected in the preliminary washing section. The cleaning liquid sprayed in the step S120 of cleaning and preheating the surface of the vehicle to be sterilized may be used at a temperature of 50 ° C or higher. That is, by using the cleaning liquid having a temperature higher than room temperature (25 ° C), it is possible to more easily clean the foreign matter adhered to the surface of the vehicle, and to increase the disinfecting efficiency in the process of disinfecting the disinfectant by pre- .

Next, the disinfecting unit performs disinfection by spraying a high-temperature cleaning liquid on the pre-heated disinfected vehicle (S130). In the step of performing disinfection (S 130), the disinfectant may be used at 65 ° C or higher. In order to further improve the disinfection efficiency, the disinfecting time may be 2 minutes, preferably 3 minutes or more.

To improve disinfection efficiency, the disinfectant may contain hypochlorous acid, or may contain hypochlorous acid and OH radical. In particular, the present invention may include a disinfectant producing unit having an OH radical generator in order to solve the problem caused by short remaining time of the OH radical.

That is, the step of performing disinfection (S120) further comprises a step of generating a disinfectant in the disinfectant producing unit, wherein the step of generating the disinfectant includes a first reaction tank and a first oxidation electrode for generating hypochlorous acid in the first reaction tank, And generating a hypochlorous acid in a hypochlorous acid generator comprising a first reducing electrode and an OH radical generator comprising a second reaction tank and a second oxidation electrode and a second reducing electrode for generating OH radicals in the second reaction tank OH < / RTI > radicals.

Meanwhile, the step S140 may include cleaning the residual disinfectant by injecting the disinfectant into the disinfection vehicle after the disinfection is performed in the disinfection unit (S130). The disinfectant solution of high concentration can cause the surface of the vehicle to be corroded. In the vehicle disinfecting method according to another embodiment of the present invention, the step of washing the disinfectant remaining in the outbound washing section is performed to prevent the vehicle from being corroded. can do.
