Description

  In the present invention, the sprayed and evaporated drug is charged, and the drug gas is attached to the surface of an object having a polarity opposite to the charged polarity of the drug gas or a non-polar object, and the drug gas is applied to the surface of the object. In addition, the ion having a polarity opposite to the polarity of the charge is previously attached to the surface portion of the object so that the drug gas can be more efficiently attached to the surface portion of the object. The present invention relates to an electric drug spraying system and a precharging system thereof.

  2. Description of the Related Art There is a drug spray system that sprays a drug to efficiently bring a drug gas to an appropriate concentration in a space and enhance the function of the drug gas as much as possible. In this drug spraying system, an aqueous solution of the drug is evaporated by an ultrasonic vibrator, the evaporated drug gas is temporarily stored in an accumulator, and then the drug gas is released outside by a blower, but a baffle plate is placed in the middle. It removes the large particle size from the evaporated chemical gas and releases it to the outside, thereby making the chemical gas in the space at an appropriate concentration and enhancing the function of the chemical gas as much as possible. . (For example, refer to Japanese Unexamined Patent Application Publication No. 2009-1000085).

  The above-mentioned drug spraying system can efficiently set the drug gas in the space to an appropriate concentration, in other words, a concentration that does not reveal the danger of the drug gas, but allows the drug gas and its function to act. The probability of contact with a desired object cannot be increased, but only safety is ensured. If only the function of the drug gas is considered, the higher the drug gas concentration in the space, the better. Therefore, even if the concentration of the drug gas in the space is such that the danger does not become apparent, the drug using static electricity that can increase the probability of contact between the drug gas and the object on which the function is desired to act. Nebulization systems are known.

  As shown in FIG. 18, this drug spraying system using static electricity has an ionization device 50 provided in the ventilation path of the apparatus, and the ionization apparatus 50 is connected to the ventilation path of the apparatus via an orifice 51. A first electrode 53 disposed in the vicinity of the orifice 51, a second electrode 54 disposed in the discharge chamber 52 so as to face the first electrode 53 and forming a high potential difference between the first electrode 53, and a discharge A gas supply device 55 that communicates with the chamber 52 and supplies the gas to be ionized to the discharge chamber 52 in a pressurized state. The gas to be ionized supplied to the discharge chamber 52 in a pressurized state is ejected from the orifice 51. Thus, it is possible to discharge negative ions to the above-described air passage while restricting the generation of ozone, to negatively ionize the gas, and to release the negatively ionized gas to the outside of the device. For example, see JP 2006-288453).

  In addition, a chemical spraying system using static electricity is a method in which a chemical solution, which is a tree extraction component, is put and a transparent container plugged with a liquid permeable member is placed on one side of a metal container containing a transpiration member. In the chemical vaporizer, which is mounted with the transparent container upside down so that it comes in contact with the member, and a ceramic heater is provided on the bottom back of the metal container, minus high pressure is placed before the discharge hole to the outside of the chemical vaporizer An ionization line connected to the unit is provided, and when the chemical solution, which is a vaporized tree extraction component, passes through the ionization line, it is negatively ionized and then discharged to the outside through the discharge hole. (For example, refer to Japanese Patent Application Laid-Open No. 09-56802).

  In addition, the medicine spraying system using static electricity is provided with a heater in the casing to constitute a transpiration unit for heating and evaporating the liquid medicine sucked up by the suction core, and a partition is provided on the mounting member, at least from the transpiration unit. The upper region is partitioned into a first space on the rear side and a second space on the front side, and a shelf is provided on the partition wall to extend the heater onto the heat generating portion, and negative ions that negatively ionize air on the shelf A generator is provided, and a discharge port communicating with the first space and a transpiration port communicating with the second space are provided at the upper part of the casing, and negative ions are discharged from the discharge port to the outside and liquid is discharged from another transpiration port to the outside. The medicine is evaporated (see, for example, JP-A-2004-242910).

  JP 2009-1000085 A   JP 2006-288453 A   Japanese Patent Application Laid-Open No. 09-56802   JP 2004-242910 A

  Although the medicine spraying system using static electricity disclosed in Patent Document 2 can release negative ions while restricting the generation of ozone to negatively ionize the gas from the gas supply device 55, the gas having a small particle diameter is minus as it is. Since it is ionized, its charge amount is small, it is difficult to adhere to the object that the function of the gas is desired to use, there is a possibility that the function cannot be used, and furthermore, the gas itself passes through the plasma space of the discharge part. In addition, there is a concern about the corrosion of the gas, and there is a possibility that the gas may chemically change, and it is necessary to make a fine adjustment such as the voltage of the discharge part in accordance with the electrical properties of the gas.

  Similarly to the case of Patent Document 2, the drug spray system using static electricity of Patent Document 3 is negatively ionized and discharged to the outside through the discharge hole when the chemical liquid, which is a vaporized tree extraction component, passes through the ionization line. Therefore, the charge amount of the vaporized chemical solution is small, it is difficult to adhere to the object that wants to use the function of gas, and there is a possibility that the function can not be used, and furthermore, the vaporized chemical solution itself passes through the ionization line, so ionization lines etc. There is a concern of causing corrosion, and there is also a possibility that the vaporized chemical solution may be chemically changed. Therefore, it is necessary to make fine adjustments such as the voltage of the minus high voltage portion according to the electrical properties of the vaporized chemical solution.

  The electrostatic drug spraying system disclosed in Patent Document 4 releases negative ions and transpiration liquid medicines to the outside separately, so there is no possibility of chemical change of the transpiration liquid medicine, but there is a probability that the transpiration liquid medicine will be negatively ionized. Since it is low and the charge amount is small, it is difficult to adhere to an object, and there is a possibility that the function of the evaporated liquid medicine cannot be used.

  Therefore, the present invention has been made in view of the above circumstances, and it is possible to increase the charge amount of the drug gas so that it is easily adhered to an object, and to suppress the deterioration of the drug gas as much as possible and to suppress the corrosion of the discharge part.

  1 and 2, the electrostatic drug spraying system 1 is composed of one or more discharge electrodes 2 and one or more counter electrodes 3 installed in the one or more discharge electrodes 2 with a predetermined space. Discharge unit 5 comprising a power source 4 for applying a predetermined voltage to the electrodes 2, 3, a chemical evaporation unit 6 for gasifying the chemical, and water vapor in the air charged by the upstream discharge unit 5 and the discharge unit 5 It comprises a reaction chamber 8 that mixes and combines the drug gas 7 released from the drug vaporization section 6 on the downstream side, and a blowing mechanism 9 that sends air into the reaction chamber 8.

  The discharge part 5 in FIG. 1 shows the simplest configuration for causing discharge. As shown in FIG. 2, the discharge electrode 2 has a needle shape and the counter electrode 3 has a cylindrical shape. A power source 4 is connected to both electrodes 2 and 3. In addition, as shown in FIG. 3, the discharge electrode 2 and the counter electrode 3 of the discharge part 5 may have a linear shape even when the discharge electrode 2 is linear, and the counter electrode 3 is sandwiched between flat plates. As shown in FIG. 4, the discharge electrode 2 may be needle-shaped and the counter electrode 3 may be a flat plate. If discharge occurs between the two electrodes 2 and 3 and the air can flow therethrough, the discharge electrode 2 and the counter electrode 3 There is no particular limitation on the shape.

  The power source 4 is not particularly limited as long as it can supply the necessary voltage and current to the discharge unit 5, but a positive charge is applied to the discharge electrode 2, a negative charge is applied, or There are three cases in which positive and negative charges are applied alternately. Depending on the nature of the discharge unit 5, one of the three types of power source 4 is selected, or one that can be switched between three types is selected. The voltage of the power supply 4 is not particularly limited, but is in the range of 1 KV to 8 KV. Further, the power source 4 for alternately applying plus and minus charges is not particularly limited, but it is better to use a commercial power source of 50 Hz to 60 Hz.

  The drug transpiration unit 6 stores and evaporates the drug, and examples of the transpiration means include a forced heating means and an ultrasonic vibration means. However, natural transpiration may be considered. The point is that the amount of drug required can be transpiration at all times, and the transpiration means is not particularly limited. Examples of the drug include chlorine dioxide (CLO2), sodium hypochlorite (NaCLO), chlorous acid (HCLO2), and ethyl alcohol (C2H5OH), but there is no particular limitation.

  The reaction chamber 8 is a chamber in which water vapor in the air charged in the discharge unit 5 and the drug gas 7 discharged from the drug transpiration unit 6 are mixed and combined, and the reaction chamber 8 includes the discharge unit 5. Are divided into an upstream reaction chamber 8a and a downstream reaction chamber 8b. The upstream reaction chamber 8a incorporates the air blowing mechanism 9, and the chemical evaporation unit 6 is provided in the downstream reaction chamber 8b. The chemical vaporization section 6 itself may be provided outside the downstream reaction chamber 8b, and a nozzle for discharging the chemical gas 7 from the chemical vaporization section 6 may be provided so as to penetrate the wall surface of the downstream reaction chamber 8b. good. Therefore, the air taken into the upstream reaction chamber 8a by the blower mechanism 9 through the inlet 12 from the external space and the water vapor contained therein pass through the cylindrical counter electrode 3 of the discharge part 5, Water vapor in the air is charged and clustered by the discharge unit 5 and enters the downstream reaction chamber 8b, and the water vapor in the charged and clustered air is supplied from the chemical evaporation unit 6 in the downstream reaction chamber 8b. The gas 10 is mixed and combined to form a cluster 10, and the cluster 10 is discharged from the outlet 13 provided in the downstream reaction chamber 8 b to the external space.

  Therefore, for example, if the polarity of the drug gas 7 that is charged with bacteria or viruses floating in the external space is opposite to that of the drug gas 7, the floating bacteria or virus and the drug gas 7 are immediately combined, The drug gas 7 acts on the floating virus. Further, when the object 11 in the external space has a polarity opposite to the polarity of the charged drug gas 7 and non-polarity, the drug gas 7 is immediately bonded to the surface portion 11 a of the object 11, and the surface portion 11 a of the object 11. The drug gas 7 acts on the bacteria and viruses attached to the cell.

  The air blowing mechanism 9 is not particularly limited as long as air can be sent into the reaction chamber 8, but a fan is usually used. In addition, a temperature gradient may be generated to send air into the reaction chamber 8, or an ion wind may be generated to send air into the reaction chamber 8. Further, the air blowing mechanism 9 may be built in the reaction chamber 8 or may be installed outside.

Next, the use situation of the electrostatic drug spraying system 1 having the above configuration will be described in detail.
First, after filling the medicine transpiration unit 6 with the medicine, the entire electrostatic medicine spraying system 1 is put into an operating state. Since the air blowing mechanism 9 operates, air enters the upstream reaction chamber 8a from the external space through the inlet 12. Further, the air passes between the needle-like discharge electrode 2 of the discharge part 5 and the cylindrical counter electrode 3, passes through the cylindrical counter electrode 3, and enters the downstream reaction chamber 8 b. In the process, when the power source 4 applies a positive charge to the discharge electrode 2, positive ions are released from the discharge electrode 2, and when the power source 4 applies a negative charge to the discharge electrode 2, the discharge electrode 2, negative ions are released, and when the power supply 4 alternately applies positive charges and negative charges to the discharge electrode 2, positive ions and negative ions are alternately released from the discharge electrode 2. For example, if the power supply 4 applies a negative charge to the discharge electrode 2, negative ions are released from the discharge electrode 2 (hereinafter, it is assumed that negative ions are released from the discharge electrode 2).

  When the air containing negative ions from the discharge electrode 2 is charged into the downstream reaction chamber 8b after the water vapor is charged, the agent evaporated from the drug evaporation section 6 in the downstream reaction chamber 8b by the evaporation means. The cluster 10 is mixed and combined with the gas 7 to become a cluster 10 and is negatively charged. The negatively charged cluster 10 is discharged from the outlet 13 of the downstream reaction chamber 8b to the external space. Since most of the bacteria and viruses floating in this external space are positively charged, these floating bacteria and airborne viruses and the cluster 10 are immediately combined, and the drugs in the cluster 10 against the airborne bacteria and airborne viruses. Gas 7 acts. In addition, since the object 11 in the external space is almost positively charged, the drug gas 7 immediately adheres to the surface portion 11a of the object 11, and the bacteria 11 and the viruses adhering to the surface portion 11a of the object 11 are attached. On the other hand, the drug gas 7 acts.

  FIG. 5 is an electrostatic drug spraying system 1A showing another embodiment of the present invention. The difference from the embodiment of FIGS. 1 to 4 is that the water evaporation unit 20 is provided in the upstream reaction chamber 8a. It is in the point provided. Therefore, the air that has entered the upstream reaction chamber 8a from the external space through the inlet 12 by the blower mechanism 9 takes in the water vapor 21 from the water transpiration unit 20 in the upstream reaction chamber 8a, and the cylinder of the discharge unit 5 Passes through the counter electrode 3. In the process, the water vapor 21 is mixed with and combined with ions generated by the discharge unit 5 to be charged, the charged water vapor 21 itself is clustered by hydrogen bonds, and the clustered water vapor 21 becomes the polarity of the discharge electrode 2. And enters the downstream reaction chamber 8b.

  The charged and clustered water vapor 21 and the chemical gas 7 from the chemical vaporization section 6 in the downstream reaction chamber 8b are combined in the downstream reaction chamber 8b, and the charged and clustered water vaporization section 20 The water vapor 21 and the chemical gas 7, that is, the cluster 10, as a whole, have the polarity of the discharge electrode 2 of the discharge unit 5 and a large charge capacity, and the cluster from the outlet 13 provided in the downstream reaction chamber 8 b. 10 is discharged into the external space. Since other configurations and operations are the same as those of the embodiment of FIGS. 1 to 4, reference numerals are attached to the drawings and detailed description thereof is omitted. The water vapor transpiration means of the water transpiration unit 20 is the same as in the first embodiment.

Next, a test for confirming the superiority of the electrostatic drug spraying system of the present invention was performed, and the results are shown.
<Test 1>
Using chlorine dioxide (CLO2) as a drug, the test was performed using the test apparatus shown in FIGS. In this test 1, when chlorine dioxide is attached to charged or charged water particles, the charged chlorine dioxide has an electric field perpendicular to its traveling direction, that is, between the aluminum electrode and pure water in FIG. When passing through the generated strong electric field, the traveling direction of chlorine dioxide was changed, and it was confirmed how much it was collected in 30 mL of pure water in 1 hour. Here, the humidifier is a commercially available ultrasonic humidifier, using Toyotomi Co., Ltd. (model TVH-5), and using the pump manufactured by Enomoto Micropump Co., Ltd. (model MX-808ST-S). The flow rate is 27 L / min. Pure water is a commercially available pure water production apparatus, and one obtained by Shibata Chemical (model PP-101) was used. The high voltage generator of the ion generator used 60 Hz alternating current. Chlorine dioxide collected on the pure water side was measured using a portable absorptiometer (model HI93738) manufactured by HANNA INSTRUMENTS (Hanna Instruments). The measurement results are shown in FIGS.

  From the results of FIGS. 9 to 11, the adhesion force is very weak if chlorine dioxide is not ionized. Even if ionized, chlorine dioxide alone has a small particle size and a small charge capacity, so the adhesion force does not increase. When water vapor is added to chlorine dioxide, the particle size is increased and the charge capacity is increased, so that the adhesion is also strong, and the superiority of the electrostatic drug spraying system of the present invention can be demonstrated.

<Test 2>
Using chlorine dioxide (CLO2) as a drug, the test was performed using the test apparatus shown in FIGS. In this test 2, when chlorine dioxide adhering to charged or charged water particles is released to the external space, it is attracted to an object charged with a polarity opposite to that of the chlorine dioxide being charged. How much is collected in 3 hours on the 30 mL side of pure water shown in part A of FIG. 13 where a positive potential of 1 KV is applied and on the 30 mL side of pure water shown in part B of FIG. 13 where no potential is applied It was confirmed. In addition, the same thing as FIG. 6 was used for the humidifier, the pump, and the chlorine dioxide generation part, and the same thing as FIG. 8 was used for the ion generation part. Furthermore, the measurement of the chlorine dioxide collected on the pure water side of the A part and the B part was performed using a portable absorptiometer (model HI93738) manufactured by HANNA. The measurement results are shown in FIG.

  From the results shown in FIG. 14, if chlorine dioxide is not ionized, the adhesion to the object is very weak. Even if ionized, chlorine dioxide alone has a small particle size and a small charge capacity. In addition, when water vapor is added to chlorine dioxide, the particle size is increased and the charge capacity is increased, so that the adhesion force to the object is enhanced, and the superiority of the electrostatic drug spraying system of the present invention can be demonstrated.

  FIG. 15 shows a pre-charging system according to an embodiment of the present invention, and this pre-charging system 30 is installed in front of the electrostatic drug spraying system 1 described above. An ionizer 34 comprising a discharge electrode 31 and one or more counter electrodes 32 installed in the one or more discharge electrodes 31 with a predetermined space, and comprising a power source 33 for applying a predetermined voltage to both the electrodes 31 and 32. Thus, the surface portion 11a of the object 11 is charged in advance with a polarity opposite to that of the drug gas 7 charged by the electrostatic drug spray system 1, and the drug gas 7 is attached to the surface portion 11a of the object 11. It is something that can be made to. The discharge electrode 31 and the counter electrode 32 of the ionizer 34 are not particularly limited in the same manner as the discharge electrode 2 and the counter electrode 3 of the electrostatic drug spraying system 1, but those shown in FIGS.

  Therefore, when a predetermined voltage is applied to the discharge electrode 31 and the counter electrode 32 of the ionizer 34 in the precharge system 30 by the power source 33, ions are generated by corona discharge between the electrodes 31 and 32, and the blower 35 is activated. Thus, the surface portion 11a of the object 11 is charged with ions in advance with the opposite polarity to that of the drug gas 7 charged by the electrostatic drug spraying system 1, and the drug gas 7 is applied to the surface portion 11a of the object 11 with the ion. The function of the chemical gas 7 can be made to act on the surface portion 11a of the object 11 more easily. The power supply 33 applies a positive charge to the discharge electrode 31, applies a negative charge, or alternately applies a positive / negative charge, as with the power supply 4 in the electrostatic drug spraying system 1. There are three types of applications. That is, the power supply 33 determines which charge is applied to the discharge electrode 31 according to the polarity with which the drug gas 7 is charged by the electrostatic drug spray system 1.

  FIG. 16 shows a pre-charging system according to another embodiment of the present invention. This pre-charging system 30A is installed in front of the electrostatic drug spraying system 1A.
