[Figure 13] This figure shows a chlorine dioxide diffusion device for a chlorine dioxide generation system according to an embodiment of the present invention, where (a) is a side view and (b) is a perspective view. [Modes for carrying out the invention]

[0020] The chlorine dioxide generator (chlorine dioxide gas generator) 1 according to an embodiment of the present invention generates chlorine dioxide using pure chlorine dioxide water 7, and as shown in Figure 1, it is configured to include a container 3 for pure chlorine dioxide water and a chlorine dioxide separation device 5.

[0021] Container 3 for pure chlorine dioxide water is designed to hold pure chlorine dioxide water 7 (for example, only pure chlorine dioxide water 7). Pure chlorine dioxide water 7 is produced using only chlorine dioxide and water (for example, pure water), and the chlorine dioxide is dissolved in the water. However, this does not mean that pure chlorine dioxide water 7 is completely free of impurities. Even pure chlorine dioxide water 7 contains trace amounts of unavoidable impurities.

[0022] The chlorine dioxide separator 5 is designed to generate chlorine dioxide (chlorine dioxide gas; gaseous chlorine dioxide) from the pure chlorine dioxide water 7 contained inside the container 3 for pure chlorine dioxide water. In other words, the chlorine dioxide separator 5 separates chlorine dioxide from the pure chlorine dioxide water 7 contained inside the container 3 for pure chlorine dioxide water and releases it outside the pure chlorine dioxide water 7.

[0023] As the chlorine dioxide separation device 5, for example, a bubbling device is employed that bubbles the pure chlorine dioxide water 7 contained inside the container 3 for pure chlorine dioxide water.

[0024] The bubbling device 5 is configured, for example, with an air pump 9, an air pipe 11 extending from the air pump 9, and a bubbling stone 13 located at the end of the air pipe 11. The air discharged from the air pump 9 passes through the air pipe 11 to the bubbling stone 13, and is then released from the bubbling stone 13 into the pure chlorine dioxide water 7 in the container 3 for pure chlorine dioxide water.

[0025] In other words, the air pump 9 is operated with the tip of the air pipe 11, which includes the bubbling stone 13, immersed in the pure chlorine dioxide water 7 contained in the container 3 for pure chlorine dioxide water. This causes numerous small bubbles 15 to be discharged from the bubbling stone 13 into the pure chlorine dioxide water 7 (aeration occurs).

[0026] The small bubbles 15 that are discharged rise within the pure chlorine dioxide water 7 and emerge from the liquid surface (top surface) of the pure chlorine dioxide water 7. The bubbles 15 that emerge from the pure chlorine dioxide water 7 enter the space 17 above the pure chlorine dioxide water 7 in the container 3 for the pure chlorine dioxide water, and eventually emerge from the container 3 for the pure chlorine dioxide water.

[0027] Furthermore, numerous small bubbles 15 discharged from the bubbling stone 13 separate the chlorine dioxide from the pure chlorine dioxide water 7. This separated chlorine dioxide also enters the space 17 above the pure chlorine dioxide water 7 in the container 3 for pure chlorine dioxide water, and eventually exits the container 3 for pure chlorine dioxide water.

[0028] The chlorine dioxide that escapes from container 3 for pure chlorine dioxide water is used, for example, to fumigate the room where the chlorine dioxide generator 1 is installed.

[0029] Alternatively, instead of using a bubbling device as the chlorine dioxide separator 5, the pure chlorine dioxide water 7 may be vibrated to release chlorine dioxide. For example, a vibrating object may be submerged in the pure chlorine dioxide water 7 to release chlorine dioxide.

[0030] Alternatively, chlorine dioxide may be released by stirring the pure chlorine dioxide solution 7. For example, a blade may be submerged in the pure chlorine dioxide solution 7 and rotated to release chlorine dioxide.

[0031] Alternatively, chlorine dioxide may be released using ultrasound. For example, an ultrasonic transducer may be submerged in pure chlorine dioxide water 7 to release chlorine dioxide. Furthermore, chlorine dioxide may be released by heating the pure chlorine dioxide water 7.

[0032] Furthermore, some kind of foaming agent (for example, citric acid + baking soda) may be used for the purpose of releasing the dissolved chlorine dioxide in the pure chlorine dioxide water 7 into the air. That is, some kind of foaming agent may be added to the pure chlorine dioxide water 7 in the container 3 for pure chlorine dioxide water, and the resulting foam will disrupt the dissolved state of chlorine dioxide and quickly release it into the air.

[0033] Furthermore, the chlorine dioxide generator 1 is configured to include a first container 19. The first container 19 is made of a material that allows chlorine dioxide (for example, only gaseous substances such as chlorine dioxide) to permeate. The first container 19 contains chlorine dioxide and substances other than chlorine dioxide. The first container 19 is also placed inside the pure chlorine dioxide water 7 in the pure chlorine dioxide water container 3.

[0034] With container 3 for pure chlorine dioxide water containing only pure chlorine dioxide water 7 or pure water, the first container 19 is placed into the pure chlorine dioxide water 7 or pure water. As a result, only chlorine dioxide is released from the first container 19 and dissolves in the pure chlorine dioxide water 7 or pure water in container 3 for pure chlorine dioxide water.

[0035] Furthermore, the chlorine dioxide generator 1 is configured to include a second container 21. The second container 21 is housed in the internal space of the first container 19. The first agent 23 is housed in the internal space (internal closed space) of the second container 21, and the second agent 25 is housed in the internal space (internal closed space) of the first container 19, which is outside the internal space of the second container 21.

[0036] Then, when the second container 21 is destroyed, the first agent 23 and the second agent 25 undergo a chemical reaction inside the first container 19, generating chlorine dioxide and substances other than chlorine dioxide.

[0037] Furthermore, the chlorine dioxide generator 1 is equipped with a chlorine dioxide diffusion device 27. The chlorine dioxide diffusion device 27 diffuses the chlorine dioxide released from the pure chlorine dioxide water 7 by bubbling using the bubbling device 5 into the air outside the container 3 for the pure chlorine dioxide water.

[0038] Here, we will explain the chlorine dioxide generator 1 in more detail.

[0039] The air pump 9 of the bubbling device 5 is formed, for example, in the shape of a rectangular parallelepiped, and a container 3 for pure chlorine dioxide water and a chlorine dioxide diffusion device 27 are mounted on top of the air pump 9. Air piping 11 extends from the air pump 9.

[0040] The chlorine dioxide diffusion device 27 is configured with a base 27A and a blade support 27B. The blade support 27B can rotate around an axis C1 extending in a predetermined horizontal direction, or it can be freely positioned by rotation. This makes it possible to change the direction of the airflow generated by the rotation of the blade 37. The rotation can be performed manually, for example, but it may also be performed automatically by an actuator such as a motor, and in a manner that oscillates periodically, for example (similar to the oscillating motion of a fan).

[0041] A discharge pipe 29 extends from the container 3 for pure chlorine dioxide water, which discharges the chlorine dioxide inside the container 3 to the outside of the container 3.

[0042] To further explain, the container 3 for pure chlorine dioxide water consists of a container body 31 and a lid 33. An opening 35 is formed at the upper end of the container body 31, and pure chlorine dioxide water 7 is contained inside the container body 31. The lid 33 is installed on the container body 31 so as to close the opening 35 of the container body 31. The lid 33 is detachable from the container body 31.

[0043] The air pipe 11 penetrates the fleshy part of the lid 33. The base end of the air pipe 11 is connected to the air outlet of the air pump 9, and the tip of the air pipe 11, including the bubbling stone 13, enters the pure chlorine dioxide water 7 inside the container body 31. The bubbling stone 13 is located on the bottom side of the container body 31.

[0044] The discharge pipe 29 extends from the lid 33 to the outside of the container 3 for pure chlorine dioxide water. Assuming that the air pipe 11 and the discharge pipe 29 are closed, the space inside the container 3 for pure chlorine dioxide water is a closed space. The space inside the container 3 for pure chlorine dioxide water is connected to the outside of the container 3 for pure chlorine dioxide water through the discharge pipe 29.

[0045] Container 3 for pure chlorine dioxide water is made of a material that is impermeable to both gases and liquids. When the first container 19 and the pure chlorine dioxide water 7 are contained within container 3 for pure chlorine dioxide water, the entire contents of the first container 19 are submerged in the pure chlorine dioxide water 7. In Figure 1, a wide-mouthed bottle-like object is shown as container 3 for pure chlorine dioxide water, but it is not limited to this, and various shapes of objects may be used as container 3 for pure chlorine dioxide water. For example, a bathtub or aquarium may be used as container 3 for pure chlorine dioxide water.

[0046] The second container 21 is, for example, an ampoule and is housed in the internal space of the first container 19.

[0047] The second container 21 is configured such that, for example, when it is destroyed by an applied force, the first agent 23 and the second agent 25 undergo a chemical reaction in the first container 19, generating chlorine dioxide. This generated chlorine dioxide permeates through the flesh of the first container 19 and dissolves in the pure chlorine dioxide water 7 in the container 3 for pure chlorine dioxide water.

[0048] The first container 19 is made of synthetic resins such as polypropylene, polyethylene, or silicone, which are elastic, chemical-resistant, and permeable only to gases. The container 3 for pure chlorine dioxide water and the second container 21 are made of synthetic resins or glass, which are chemical-resistant and impermeable to gases and liquids.

[0049] In any case, the first agent 23 and the second agent 25 react chemically to produce chlorine dioxide as a gas under normal temperature and pressure.

[0050] More specifically, the first agent 23 contains sodium chlorite (for example, an aqueous solution of sodium chlorite), and the second agent 25 contains citric acid (for example, citric acid in powder or tablet form).

[0051] Furthermore, the first drug 23 and the second drug 25 may be swapped. That is, citric acid may be contained in the internal space of the second container 21, and sodium chlorite may be contained in the internal space of the first container 19, which is outside the second container 21.

[0052] When the second container 21 breaks, a chemical reaction occurs in the first container 19 between sodium chlorite and citric acid, producing chlorine dioxide, sodium citrate, sodium chloride, and water. This reaction can be expressed as the equation: "15NaClO2 + 4C(OH)(CH2COOH)2COOH → 12ClO2 + 4C6H5Na3O7 + 3NaCl + 2H2O".

[0053] Then, only chlorine dioxide permeates the fleshy part of the first container 19 and dissolves in the pure chlorine dioxide water 7 stored in the container 3 for pure chlorine dioxide water.

[0054] The chlorine dioxide diffusion device 27 is equipped with a blade 37. The blade 37 is located below the outlet of the discharge pipe 29. As the blade 37 rotates, an airflow is generated from below the blade 37 to above it. This generated airflow diffuses the chlorine dioxide that has come out of the outlet of the discharge pipe 29.

[0055] Next, we will explain the operation of the chlorine dioxide generator 1.

[0056] Initially, the second container 21 is destroyed, the container 3 for pure chlorine dioxide water contains pure chlorine dioxide water 7, and the air pump 9 and chlorine dioxide diffusion device 27 are stopped.

[0057] In the initial state described above, when the air pump 9 and the chlorine dioxide diffusion device 27 are operated, chlorine dioxide is released from the outlet of the discharge pipe 29, and this released chlorine dioxide is diffused by the chlorine dioxide diffusion device 27.

[0058] Furthermore, when there is sufficient chlorine dioxide dissolved in the pure chlorine dioxide water 7 in container 3 for pure chlorine dioxide water, the pure chlorine dioxide water 7 will have a yellowish color, and when the amount of dissolved chlorine dioxide decreases, the pure chlorine dioxide water 7 will become colorless and transparent.

[0059] Once the pure chlorine dioxide solution 7 becomes colorless and transparent, replace the old first container 19 (the first container 19 in which the second container 21 was destroyed) with a new first container 19.

[0060] The chlorine dioxide generator 1 comprises a container 3 for pure chlorine dioxide water, which contains pure chlorine dioxide water, and a chlorine dioxide separator 5 that separates chlorine dioxide from the pure chlorine dioxide water 7 inside the container 3 and releases it outside the pure chlorine dioxide water 7.

[0061] Here, by appropriately adjusting the operating state of the chlorine dioxide separator 5, it is possible to prevent the concentration of chlorine dioxide coming out (released) from the chlorine dioxide generator 1 from becoming too high or too low. In other words, by adjusting the amount of air (amount of bubbles 15) coming out of the chlorine dioxide separator 5, the concentration of the generated chlorine dioxide gas can be controlled.

[0062] Furthermore, since the chlorine dioxide generator 1 is configured to separate chlorine dioxide from pure chlorine dioxide water 7 and release it, the device configuration is simpler compared to cases where chlorine dioxide is released through a chemical reaction of multiple types of chemicals. Also, if the first container 19 and the second container 21 are not used, and the pure chlorine dioxide water 7 is simply placed in the container 3 for pure chlorine dioxide water, no chemical reaction occurs, eliminating concerns about corrosion caused by by-products generated by the chemical reaction. This makes it possible to install the chlorine dioxide generator 1 in places where people are nearby, such as rooms, without worry.

[0063] Furthermore, in the chlorine dioxide generator 1, since the chlorine dioxide is dissolved in water, storage of the chlorine dioxide is easy and safety is ensured. The water also acts like a battery, contributing to the space-saving storage of the chlorine dioxide.

[0064] In this case, chlorine dioxide is being generated, but if an explosive gas were to be used instead of chlorine dioxide, dissolving it in water would be far safer than handling the explosive gas directly.

[0065] Furthermore, since the chlorine dioxide generator 1 employs a bubbling device as the chlorine dioxide separator 5, the configuration is even simpler, and the time from the start of operation of the bubbling device 5 until chlorine dioxide is released can be minimized.

[0066] Furthermore, in the chlorine dioxide generator 1, the first container 19 is made of a material that only chlorine dioxide permeates, and the first container 19, which contains chlorine dioxide and other substances, is placed inside the container 3 for pure chlorine dioxide water.

[0067] This allows for the safe and comfortable generation of pure chlorine dioxide water 7 within the container 3 for pure chlorine dioxide water. Furthermore, when chlorine dioxide is released by bubbling and the concentration of chlorine dioxide in the pure chlorine dioxide water 7 decreases, the equilibrium state is broken. This allows for the replenishment of chlorine dioxide from the first container 19 into the pure chlorine dioxide water 7, thereby restoring the equilibrium state. In other words, the concentration of chlorine dioxide in the pure chlorine dioxide water 7 within the container 3 for pure chlorine dioxide water can be kept nearly constant for a long period of time.

[0068] Furthermore, the chlorine dioxide generator 1 is configured such that when the second container 21 is destroyed, the first chemical agent 23 and the second chemical agent 25 undergo a chemical reaction inside the first container 19, generating chlorine dioxide. As a result, the chemical reaction does not occur until the second container 21 is destroyed, and the first container 19 containing the second container 21, which is constructed with the second container 21 inside the first container 19, can be stored for a long period of time. In other words, the equipment that serves as the source of chlorine dioxide generation (the first container 19 containing the second container 21) can be stored for a long period of time.

[0069] Furthermore, when the concentration of chlorine dioxide in the container 3 for pure chlorine dioxide water reaches saturation, the amount of chlorine dioxide that permeates through the body of the first container 19 and enters the container 3 for pure chlorine dioxide water from the first container 19 becomes almost negligible. As a result, chemical reactions within the first container 19 are suppressed, and the generation of chlorine dioxide within the first container 19 is inhibited. This allows for the replenishment of an appropriate amount of chlorine dioxide from the first container 19 to the pure chlorine dioxide water 7 in the container 3 for pure chlorine dioxide water over a long period of time.

[0070] Furthermore, the chlorine dioxide generator 1 uses a chlorine dioxide diffusion device 27 to diffuse the chlorine dioxide released from the pure chlorine dioxide water 7 into the air. This allows the chlorine dioxide gas, which is heavier than air, to be properly diffused in the air.

[0071] Next, the chlorine dioxide generator 1a according to the first modification will be described with reference to Figure 2. The chlorine dioxide generator 1a according to the first modification differs from the chlorine dioxide generator 1 according to the embodiment of the present invention in that it uses air discharged from the air pump 9 as the chlorine dioxide diffusion device 27, but in other respects it is configured the same as the chlorine dioxide generator 1.

[0072] To explain further, the chlorine dioxide generator 1a is configured to include a discharge pipe 39 separate from the air pipe 11 and the discharge pipe 29.

[0073] The tip of the discharge pipe 29 is connected to the first opening of a tee 41, which is a type of piping component. The base end of the discharge pipe 39 is connected to the air pump 9, and the tip of the discharge pipe 39 is connected to the second opening of the tee 41. The third opening of the tee 41 is open to the atmosphere.

[0074] When the air pump 9 is activated, air flows through the discharge pipe 39. The air that has flowed through the discharge pipe 39 to the tee 41 is released into the atmosphere through the third opening of the tee 41. At this time, the chlorine dioxide that has come out of the discharge pipe 29 is also released into the atmosphere. This causes the chlorine dioxide to diffuse. By using this method, chlorine dioxide can be supplied almost intensively to a location far from the chlorine dioxide generator 1a.

[0075] In Figure 2, a check valve 43 is provided in the middle of the discharge pipes 29 and 39, but the check valve 43 may be omitted. Furthermore, without using the tee 41, the chlorine dioxide coming out of the discharge pipe 29 may be released into the atmosphere by the Venturi effect of the airflow discharged from the discharge pipe 39.

[0076] Next, the chlorine dioxide generator 1b according to the second modification will be described with reference to Figure 3. The chlorine dioxide generator 1b according to the second modification differs from the chlorine dioxide generator 1 and chlorine dioxide generator 1a in that it is equipped with a rod-shaped member 45, but in other respects it is configured in the same way as the chlorine dioxide generators 1 and 1a.

[0077] The rod-shaped member 45 is configured to allow for easy adjustment of its length, and after setting its length to a predetermined value, it maintains that length. The longitudinal direction of the rod-shaped member 45 is, for example, the vertical direction (including a diagonal direction that is slightly inclined relative to the vertical direction).

[0078] To further explain, the rod-shaped member 45 is a telescopic type composed of, for example, multiple rod-shaped member components 45A, 45B, and 45C. Figure 3(a) shows the state where the length dimension of the rod-shaped member 45 is at its maximum value, and Figure 3(b) shows the state where the length dimension of the rod-shaped member 45 is at its minimum value.

[0079] The container 3 for pure chlorine dioxide water, the chlorine dioxide separation device 5, the air pump 9, and the discharge piping 29 are installed, for example, on the uppermost rod-shaped component 45C.

[0080] The discharge pipe 29 is installed such that at least the longitudinal direction of its tip is vertical, and the upper end of the discharge pipe 29 is located above the upper end of the rod-shaped component 45C.

[0081] Furthermore, a rod-shaped member erection device 47, such as a tripod, is provided at the lower end of the rod-shaped member 45 to erect the rod-shaped member 45 on the floor surface 49.

[0082] Next, the third modified chlorine dioxide generator 1c will be described with reference to Figure 4. In the third modified chlorine dioxide generator 1c, the container 3 for pure chlorine dioxide water, the chlorine dioxide separator 5, and the air pump 9 are provided on the floor surface 49 near the rod-shaped member 45 or at the lower end of the rod-shaped member 45. These points differ from the second modified chlorine dioxide generator 1b, while other aspects are configured similarly to the chlorine dioxide generator 1b.

[0083] To explain further, the discharge pipe 29 is installed along the rod-shaped member 45, and regardless of the length of the rod-shaped member 45, the tip of the discharge pipe 29 is positioned at or near the upper end of the rod-shaped member 45.

[0084] To explain further, the discharge pipe 29 passes through the inside of the cylindrical rod-shaped member 45. The discharge pipe 29 protrudes, for example, above the rod-shaped member 45.

[0085] In the chlorine dioxide generator 1c, the tip of the discharge pipe 29 is positioned at or near the upper end of the rod-shaped member 45, regardless of the length of the rod-shaped member 45. This allows chlorine dioxide gas, which is heavier than air, to be released into the room air from, for example, a high point in the room, and the chlorine dioxide gas to be properly diffused.

[0086] Next, the chlorine dioxide generator 1d according to the fourth modification will be explained with reference to Figure 5. The chlorine dioxide generator 1d according to the fourth modification differs from the chlorine dioxide generator 1b according to the second modification in that it is equipped with a web camera 51, etc., but in other respects it is configured in the same way as the chlorine dioxide generator 1b and other chlorine dioxide generators.

[0087] To explain further, the chlorine dioxide generator 1d is configured to include a container 3 for pure chlorine dioxide water, a chlorine dioxide separator 5, an air pump 9, a chlorine dioxide diffusion device 27, a rod-shaped member 45, a web camera 51, and a control device 53, among other things.

[0088] The webcam 51 is configured to capture images of at least the container 3 for pure chlorine dioxide water. The video captured by the webcam 51 can then be displayed in real time, for example, on a communication terminal (a video receiving device such as a tablet or mobile device) 55 via a communication line such as the internet.

[0089] Although the webcam 51 is located at the upper end of the rod-shaped member 45, it may also be located in the middle or other parts of the rod-shaped member 45 in the longitudinal direction.

[0090] Furthermore, the chlorine dioxide generator 1d is equipped with a first chlorine dioxide concentration sensor 57, a second chlorine dioxide concentration sensor 59, a pure chlorine dioxide water volume detection sensor 61, and a high-concentration pure chlorine dioxide water supply device 63.

[0091] The first chlorine dioxide concentration sensor 57 measures the concentration of chlorine dioxide dissolved in the pure chlorine dioxide water 7 contained in the container 3 for pure chlorine dioxide water. The second chlorine dioxide concentration sensor 59 measures the concentration of chlorine dioxide in the air outside the container 3, either near or around the container 3 for pure chlorine dioxide water. Multiple second chlorine dioxide concentration sensors 59 may be provided. These multiple second chlorine dioxide concentration sensors 59 are installed at a distance from each other.

[0092] The pure chlorine dioxide water volume detection sensor 61 is designed to detect the amount of pure chlorine dioxide water 7 contained in the pure chlorine dioxide water container 3. The high-concentration pure chlorine dioxide water supply device 63 supplies high-concentration pure chlorine dioxide water, which has a high (concentrated) concentration of dissolved chlorine dioxide, into the pure chlorine dioxide water container 3. The concentration of chlorine dioxide dissolved in the high-concentration pure chlorine dioxide water is higher than the concentration of chlorine dioxide dissolved in the pure chlorine dioxide water 7 contained in the pure chlorine dioxide water container 3.

[0093] The amount of pure chlorine dioxide water detected by the pure chlorine dioxide water volume detection sensor 61 is displayed, for example, in real time on the communication terminal 55 via a communication line such as the internet.

[0094] The control device 53 is configured, for example, to include memory and a CPU. The control device 53 controls the supply of a predetermined amount of high-concentration pure chlorine dioxide water from the high-concentration pure chlorine dioxide water supply device 63 into the container 3 for pure chlorine dioxide water, according to the concentration of chlorine dioxide detected by the first chlorine dioxide concentration sensor 57.

[0095] Specifically, when the concentration of chlorine dioxide in the pure chlorine dioxide water 7 contained in the pure chlorine dioxide water container 3 is less than a first threshold, the supply of high-concentration pure chlorine dioxide water to the pure chlorine dioxide water container 3 begins. On the other hand, when the concentration of chlorine dioxide in the pure chlorine dioxide water 7 contained in the pure chlorine dioxide water container 3 is greater than a second threshold, the supply of high-concentration pure chlorine dioxide water to the pure chlorine dioxide water container 3 is stopped. The second threshold is greater than the first threshold. Furthermore, the supply of high-concentration pure chlorine dioxide water may be stopped when the amount of pure chlorine dioxide water 7 detected by the pure chlorine dioxide water quantity detection sensor 61 exceeds a predetermined value. An alarm may also be issued from the communication terminal 55.

[0096] Furthermore, the control device 53 adjusts the amount of air discharged from the air pump 9 according to the concentration of chlorine dioxide detected by the second chlorine dioxide concentration sensor 59 (including cases where the amount of air is "0", i.e., when the air pump 9 is stopped).

[0097] In other words, the air pump 9 is set to start operating when the concentration of chlorine dioxide in the air outside the container 3 for pure chlorine dioxide water is less than the third threshold. On the other hand, the air pump 9 is set to stop when the concentration of chlorine dioxide in the air outside the container 3 for pure chlorine dioxide water is greater than the fourth threshold. Note that the fourth threshold is greater than the third threshold.

[0098] The chlorine dioxide diffusion device 27 is installed on the rod-shaped member 45. The discharge pipe 29 for the chlorine dioxide diffusion device 27 generates an airflow that guides the chlorine dioxide coming out of the discharge port upwards.

[0099] The chlorine dioxide generator 1d has a webcam 51 that photographs the container 3 for pure chlorine dioxide water, so the chlorine dioxide generator 1d can be observed remotely, and any malfunctions in the container 3 for pure chlorine dioxide water can be visually identified.

[0100] Incidentally, when using the generated chlorine dioxide for fumigation, it is undesirable for the chlorine dioxide to contain moisture during fumigation. For this reason, a separation device (such as a filter or a device that utilizes liquefaction of water vapor by cooling) may be installed in the chlorine dioxide generator 1d (1~1c) to separate the water vapor, and the chlorine dioxide from which the moisture has been removed may be discharged from the discharge pipe 29.

[0101] The chlorine dioxide generator 1d is configured to include a first chlorine dioxide concentration sensor 57, a second chlorine dioxide concentration sensor 59, a pure chlorine dioxide water volume detection sensor 61, and a high-concentration pure chlorine dioxide water supply device 63.

[0102] This allows the concentration of chlorine dioxide in the room where the chlorine dioxide generator 1d is installed to be automatically adjusted to an appropriate value.

[0103] In addition, in the chlorine dioxide generator 1d, etc., a timer may be used to determine the operating time of the chlorine dioxide separator, instead of or in addition to providing the control device 53, etc. This ensures safety by preventing the concentration of chlorine dioxide from becoming too high even if the sensor breaks down, through timer settings.

[0104] In this case, pure chlorine dioxide water 7 or high-concentration pure chlorine dioxide water may be directly supplied into the container 3 for pure chlorine dioxide water without providing the first container 19 and the second container 21. The production apparatus for pure chlorine dioxide water 7 or high-concentration pure chlorine dioxide water used in this case will be explained with reference to Figures 6 to 8.

[0105] The pure chlorine dioxide water production apparatus 101 according to the first embodiment of the present invention is configured to include a first device 103 and a second device 105, as shown in Figures 7 and 8.

[0106] The first vessel 103 is made of a material that allows a predetermined substance (for example, chlorine dioxide 115) to permeate, and contains chlorine dioxide 115 and a substance other than chlorine dioxide 117 inside. The second vessel 105 contains water 107 and the first vessel 103 inside. The chlorine dioxide 115 that permeates through the first vessel 103 and comes out of the first vessel 103 dissolves (remains dissolved) in the water 107 inside the second vessel 105. For example, the water 107 can be pure water such as "purified water" as defined in the Japanese Pharmacopoeia.

[0107] Furthermore, the pure chlorine dioxide water production apparatus 101 is equipped with a substance mixing unit 109, as shown in Figures 6 to 8. In the substance mixing unit 109, a first pre-reaction substance (for example, chlorous acid) 111 and a second pre-reaction substance (for example, citric acid) 113 are mixed.

[0108] Chlorite 111 and citric acid 113, which have been combined in the substance mixing unit 109, undergo a chemical reaction to produce chlorine dioxide 115. Chlorite 111 and citric acid 113 exist, for example, in the form of an aqueous solution.

[0109] The chemical reaction between chlorous acid 111 and citric acid 113 can be represented by the reaction equation, as shown above: "15NaClO2 + 4C(OH)(CH2COOH)2COOH → 12ClO2 + 4C6H5Na3O7 + 3NaCl + 2H2O". Here, "C6H5Na3O7", "NaCl", and "H2O" produced in the above reaction equation are by-products (unwanted substances) that make up substance 117 other than chlorine dioxide.

[0110] Furthermore, the first vessel 103 is made of a synthetic resin such as polypropylene, polyethylene, or silicone that is chemical-resistant and permeable only to gases. As a result, only the chlorine dioxide 115 produced by the above chemical reaction permeates through the first vessel 103 and dissolves in the water inside the second vessel 105. On the other hand, the second vessel 105 is made of a material that does not allow water 107, chlorine dioxide 115, or by-products 117 to permeate, such as glass or a synthetic resin with a predetermined coating.

[0111] As shown in Figures 7 and 8, the first object 103 is composed of a first tube. The second object 105 is composed of a second tube. The second tube 105 is made of a synthetic resin or the like, which has been appropriately coated as described above. As a result, the substance described in the above reaction equation does not permeate the second tube 105. The first object 103 and the second tube 105 are, for example, flexible.

[0112] The first tube 103 is located inside the second tube 105. The first tube 103 is configured to allow chlorine dioxide 115 and a substance other than chlorine dioxide 117 to flow through it. Additionally, water is configured to flow through the space 119 inside the second tube 105, which is outside the first tube 103.

[0113] The first tube 103 is formed in an elongated cylindrical shape, and the second tube 105 is also formed in an elongated cylindrical shape. The outer diameter of the first tube 103 is smaller than the inner diameter of the second tube 105.

[0114] The longitudinal direction of the first tube 103 and the longitudinal direction of the second tube 105 coincide, and the first tube 103 extends within the second tube 105. A cylindrical space 119 is formed in the portion of the second tube 105 excluding the first tube 103, and water 107 flows through this cylindrical space 119.

[0115] The direction in which chlorine dioxide 115 and other substances 117 flow coincides with the longitudinal direction of the first tube 103, and the direction in which water 107 flows coincides with the longitudinal direction of the second tube 105.

[0116] The direction in which chlorine dioxide 115 and other substances 117 flow within the first tube 103 is opposite to the direction in which water 107 flows within the second tube 105, which is outside the first tube 103 (see arrow in Figure 7).

[0117] Let's explain the pure chlorine dioxide water production apparatus 101 in more detail.

[0118] As shown in Figure 6, the pure chlorine dioxide water production apparatus 101 comprises a stand 121, a first pre-reaction material tank 123, a second pre-reaction material tank 125, a water tank 127, an aqueous solution tank 129, and a by-product tank 131.

[0119] Furthermore, the pure chlorine dioxide water production apparatus 101 is equipped with a first pre-reaction substance pump (for example, a tubular pump for chlorite) 133, a second pre-reaction substance pump (for example, a tubular pump for citric acid) 135, and a water pump 137, as shown in Figure 6.

[0120] Furthermore, the pure chlorine dioxide water production apparatus 101 is equipped with a predetermined substance permeation section (for example, a chlorine dioxide permeation section) 139, a temperature control section 141, and a control unit (a control unit equipped with a CPU and memory, not shown) 143.

[0121] Each of the tanks 123, 125, 127, 129, and 131, as well as each of the pumps 133, 135, and 137, are mounted on the frame 121. For example, variable-volume tube pumps are used for each of the pumps 133, 135, and 137.

[0122] The chlorous acid tank 123 stores an aqueous solution of chlorous acid 111, the citric acid tank 125 stores an aqueous solution of citric acid 113, and the water tank 127 stores water 107. The chlorine dioxide aqueous solution tank 129 stores an aqueous solution 102 of chlorine dioxide 115, and the by-product tank 131 stores the by-product 117.

[0123] An intake tube 145 extends from the intake port of the chlorite-supply tube pump 133. The tip of the intake tube 145 is inside the chlorite-supply tank 123. A discharge tube 147 extends from the discharge port of the chlorite-supply tube pump 133.

[0124] A suction tube 149 extends from the suction port of the citric acid tube pump 135. The tip of the suction tube 149 is inside the citric acid tank 125. A discharge tube 151 extends from the discharge port of the citric acid tube pump 135.

[0125] The tip of discharge tube 147 and the tip of discharge tube 151 are connected to each other, and a material matching section 109 is formed at this connection point. The first tube 103 extends from the material matching section 109 toward the by-product tank 131.

[0126] In the material mixing section 109, the aqueous solution of chlorous acid 111 and the aqueous solution of citric acid 113 mix together, causing a chemical reaction to occur and produce chlorine dioxide 115 and by-products 117. These chlorine dioxide 115 and by-products 117 flow through the first tube 103 toward the by-product tank 131.

[0127] A suction tube 153 extends from the intake port of the water pump 137. The tip of the suction tube 153 is inside the water tank 127. A discharge tube 155 extends from the discharge port of the water pump 137.

[0128] The tip of the discharge tube 155 is connected to the second tube 105, and from this connection point, the second tube 105 extends toward the tank 129 for the aqueous solution of chlorine dioxide 115. A discharge tube 130 extends from the tip of the second tube 105.

[0129] The tip of the discharge tube 130 is inserted into the tank 129 for the chlorine dioxide 115 aqueous solution. This causes the water 107 and the chlorine dioxide 115 aqueous solution 2 to flow from the water tank 127 towards the chlorine dioxide 115 aqueous solution tank 129.

[0130] A portion of the first tube 103 in the longitudinal direction (for example, most of the middle section) extends inside the second tube 105, as shown in Figures 7 and 8. The portion of the first tube 103 that extends inside the second tube 105 forms the chlorine dioxide permeable section 139. In the chlorine dioxide permeable section 139, chlorine dioxide 115 exits the first tube 103 and dissolves into the water 107 inside the second tube 105.

[0131] The temperature control section 141 shown in Figure 6 adjusts the temperature of the first tube 103 and the second tube 105 in a portion of the longitudinal direction of the chlorine dioxide permeate section 139 (for example, most of the middle section). That is, the temperature control section 141 adjusts the temperature of the aqueous solution of chlorous acid 111, the aqueous solution of citric acid 113, chlorine dioxide 115, by-products 117, and water 107. The temperature of the first tube 103 and the second tube 105 is adjusted as appropriate within a range of, for example, -9°C to 60°C. Furthermore, at the temperature control section 141, as shown in Figure 6, the first tube 103 and the second tube 105 forming the chlorine dioxide permeate section 139 extend in a coiled (spiral) shape. Note that the chlorine dioxide permeate section 139 may also bend and extend in other forms, such as meandering, at the temperature control section 141.

[0132] The temperature control unit 141 will be further explained with reference to Figure 6. The temperature control unit 141 comprises a container 142, a predetermined liquid 144 such as antifreeze contained within the container 142, and a temperature controller 46 for adjusting the temperature of this predetermined liquid. A coil-shaped chlorine dioxide permeable section 139 is housed within the predetermined liquid 144.

[0133] One longitudinal end of the second tube 105 (the end on the water pump 137 side) is connected to the first connector 159 of the tee 157, as shown in Figure 8(b). The second connector 161 of the tee 157 is connected to the discharge tube 155.

[0134] The other longitudinal end of the second tube 105 (the end on the side of the tank 129 for the aqueous solution of chlorine dioxide 115) is connected to the first connector 165 of the tee 163, as shown in Figure 8(c). The second connector 167 of the tee 163 is connected to the discharge tube 130.

[0135] A bush 171 is installed at the third connection point 169 of the tee 157, as shown in Figure 8(b). A bush 175 is installed at the third connection point 173 of the tee 157, as shown in Figure 8(c).

[0136] The first tube 103 then passes through the second tube 105, passing through each of the bushes 171 and 175. Reference numeral 177 in Figures 8(b) and 8(c) indicates a deformation prevention member for preventing deformation of the first tube 103. The deformation prevention member 177 is formed in a cylindrical shape and has high rigidity.

[0137] In the state shown in Figure 8(b), the bush 171 and the first tube 103 are held in place with a predetermined pressure by the third connection portion 69 of the tee 157 and the deformation prevention member 177. In the state shown in Figure 8(c), the bush 175 and the first tube 103 are also held in place with a predetermined pressure by the third connection portion 173 of the tee 157 and the deformation prevention member 177.

[0138] When pumps 133, 135, and 137 are driven, chlorine dioxide 115, by-products 117, water 107, etc., flow without leaking out of the first tube 103 or the second tube 105, as shown by the arrows in Figures 6 to 8. It is desirable that the portion of the first tube 103 that extends outside the second tube 105 be coated, similar to the second tube 105, to prevent water 107, chlorine dioxide 115, and by-products 117 from permeating through.

[0139] Next, the operation of the pure chlorine dioxide water production apparatus 101 will be described.

[0140] In the initial state, the chlorous acid tank 123 contains an aqueous solution of chlorous acid 111, and the citric acid tank 125 contains an aqueous solution of citric acid 113. Additionally, the water tank 127 contains water 107, while the aqueous solution tank 129 and the by-product tank 131 are empty. Pumps 133, 135, and 137 are stopped.

[0141] In the initial state described above, under the control of the control unit 143, the temperature is first adjusted by the temperature adjustment unit 141. Subsequently, the pumps 133, 135, and 137 are started. Pumps 133 and 135 are operated intermittently, for example, because the amount of chlorine dioxide 115 produced per predetermined time can be very small. In contrast, the water pump 137 is operated continuously, for example.

[0142] As a result, an aqueous solution of chlorine dioxide 115 2 is stored in the tank 129 for the aqueous solution of chlorine dioxide 115, and the by-product 117 is stored in the by-product tank 131.

[0143] In the pure chlorine dioxide water production apparatus 101, the first tube 103 and water 107 are contained within the second tube 105, and chlorine dioxide 115 is allowed to pass through the first tube 103 and exit the first tube 103. Furthermore, the chlorine dioxide 115 that has exited the first tube 103 dissolves in the water 107 inside the second tube 105. This makes it possible to obtain the required chlorine dioxide (chlorine dioxide free from impurities such as by-products) and improves the usability of the obtained chlorine dioxide.

[0144] For example, the presence of chlorine dioxide 115 dissolved in water 107 slows down the dispersion rate of chlorine dioxide 115, making it easier to use. For instance, if water 107 containing only dissolved chlorine dioxide 115 is sprayed in a mist onto a table to be disinfected, the chlorine dioxide 115 will be gradually released from the water 107, allowing the disinfecting effect to be sustained.

[0145] Furthermore, the pure chlorine dioxide water production apparatus 101 is designed to generate chlorine dioxide 115 through a chemical reaction when chlorous acid 111 and citric acid 113 are combined. This allows for the timely acquisition of unstable chlorine dioxide 115 as needed.

[0146] Furthermore, in the pure chlorine dioxide water production apparatus 101, the first tube 103 is located inside the second tube 105. Chlorine dioxide 115 and other substances 117 flow through the first tube 103, while water 107 flows through the second tube 105, outside the first tube 103. This allows for the efficient production of an aqueous solution 2 of chlorine dioxide 115 in a continuous manner.

[0147] In the pure chlorine dioxide water production apparatus 101, the direction in which chlorine dioxide 115 and other substances 117 flow through the first tube 103 is opposite to the direction in which water 107 flows through the second tube 105. This allows for more efficient production of an aqueous solution 102 of chlorine dioxide 115.

[0148] In other words, the concentration of chlorine dioxide 115 is high upstream in the direction in which chlorine dioxide 115 and other substances 117 flow, and low downstream in the direction in which chlorine dioxide 115 and other substances 117 flow. Also, the concentration of chlorine dioxide 115 is low upstream in the direction in which water 107 flows, and high downstream in the direction in which water 107 flows.

[0149] Furthermore, on one side in the longitudinal direction between the first tube 103 and the second tube 105, the concentration of chlorine dioxide 115 is higher in both the first tube 103 and the second tube 105. On the other side in the longitudinal direction between the first tube 103 and the second tube 105, the concentration of chlorine dioxide 115 is lower in both the first tube 103 and the second tube 105.

[0150] This minimizes the bias in the amount of chlorine dioxide 115 permeating through the first tube 103 in the longitudinal direction between the first tube 103 and the second tube 105, making it possible to obtain the aqueous solution 2 of chlorine dioxide 115 more efficiently.

[0151] In the above explanation, the case of obtaining an aqueous solution 2 of chlorine dioxide 115 was used as an example, but the pure chlorine dioxide water production apparatus 101 can also be used as is, or in a form that is appropriately modified, when obtaining aqueous solutions of substances other than chlorine dioxide. For example, an aqueous solution of fragrance can be obtained from a mixture of fragrance and non-fragrance substances.

[0152] Here, the fifth modified chlorine dioxide generator 1e will be described with reference to Figure 10. The fifth modified chlorine dioxide generator 1e has a housing 181. The housing 181 is configured, for example, with a vertically elongated columnar portion 183 and a horizontally elongated upper portion 185.

[0153] The upper portion 185 extends horizontally from the upper end of the columnar portion 183. As a result, the housing 181 is formed in an "L" shape (more precisely, an inverted "L" shape) when viewed from the side.

[0154] Container 3 is configured to be installed in the housing 181 so as to be aligned with the columnar portion 183 below the upper portion 185. Container 3 is formed in a bottomed cylindrical shape (for example, a bottomed cylindrical shape), and is installed in the housing 181 so as to engage the opening at its upper end with the upper portion 185.

[0155] The compressed air generating unit (air pump) 9 of the bubbling device 5, which generates compressed air, is housed within the columnar section 183. The compressed air generated by the compressed air generating unit 9 is supplied to the container 3 (pure chlorine dioxide water 7) through a pipe 187 that extends between the housing 181 and the container 3 installed in the housing 181.

[0156] This configuration ensures that the chlorine dioxide separated from the pure chlorine dioxide water 7 in container 3 and released from container 3 passes through the upper part 185 of the housing 181 and is released to the outside of the housing 181. Reference numeral 189 in Figure 10 indicates a channel through which the separated chlorine dioxide exits the housing 181.

[0157] In the chlorine dioxide generator 1e, the container 3 is installed on the housing 181, for example, in a detachable manner, so as to be aligned with the columnar portion 183 below the upper portion 185 of the housing 181. As a result, the exterior of the chlorine dioxide generator 1e with the container 3 installed has a clean, rectangular parallelepiped shape with almost no protrusions. This creates an aesthetically pleasing appearance, makes it easy to carry, easy to install, and reduces the space required for installation.

[0158] Next, a chlorine dioxide generating system 201 according to an embodiment of the present invention will be described with reference to Figures 9, 11 to 13.

[0159] As shown in Figure 9, the chlorine dioxide generation system 201 is configured to include a chlorine dioxide generator (for example, multiple chlorine dioxide generators) 1e and a chlorine dioxide generator control device 203. Note that other chlorine dioxide generators, such as chlorine dioxide generator 1, may be used as chlorine dioxide generators other than chlorine dioxide generator 1e.

[0160] The chlorine dioxide generator 1e is to be installed inside room 205 (a nearly sealed room 205 in building 207). The release (discharge) of chlorine dioxide from multiple chlorine dioxide generators 1e is to occur at multiple locations within room 205. These multiple locations within room 205 are spaced appropriately apart from each other to ensure that the concentration of chlorine dioxide within room 205 is as uniform as possible.

[0161] The chlorine dioxide generator control device 203 is formed, for example, in the shape of a rectangular parallelepiped, as shown in Figure 11, and is installed inside the room 205. The chlorine dioxide generator control device 203 comprises a chlorine dioxide concentration measuring sensor 209, a chlorine dioxide generator control unit 211, a communication unit (for example, a wireless communication unit) 213, and a monitor unit (for example, an information display unit consisting of an LCD) 215.

[0162] The chlorine dioxide concentration measuring sensor 209 is designed to measure the concentration of chlorine dioxide in the air (in the air inside room 205). As shown in Figure 11, chlorine dioxide reaches the chlorine dioxide concentration measuring sensor 209 inside the chlorine dioxide generator control device 203 through the opening of the protruding part 217 of the chlorine dioxide generator control device 203.

[0163] The chlorine dioxide generator control unit 211 is configured to include a CPU and memory (not shown). Furthermore, the chlorine dioxide generator control unit 211 is configured to stop the operation of the chlorine dioxide generator 1e after it has started operating and begun generating chlorine dioxide. More specifically, the chlorine dioxide concentration detected by the chlorine dioxide concentration measuring sensor 209 exceeds a predetermined threshold (a concentration sufficient to disinfect the room 205; for example, 0.5 ppm). At this point, the chlorine dioxide generator control unit 211 stops the operation of the chlorine dioxide generator 1e.

[0164] The chlorine dioxide generator control device 203 (chlorine dioxide concentration measuring sensor 209) is installed at a suitable distance from the multiple chlorine dioxide generators 1e, for example, in a plan view, at the center of the multiple chlorine dioxide generators 1e. In the vertical direction, it is positioned on the floor of room 205, at a predetermined distance (for example, 0.3m to 3m) above the floor of room 205.

[0165] As shown in Figure 9, the chlorine dioxide generator 1e is equipped with a communication unit (for example, a wireless communication unit) 219 and a control unit 221 which includes a CPU and memory (not shown). The chlorine dioxide generator control unit 211 of the chlorine dioxide generator control device 203 and the communication unit 219 of the chlorine dioxide generator 1e are able to communicate with each other using wireless communication means such as wireless LAN (infrared rays or ultrasound may also be used instead of radio waves). The chlorine dioxide generator control unit 211 is configured to stop the operation of the chlorine dioxide generator 1e using wireless communication means.

[0166] Furthermore, the chlorine dioxide generation system 201 is configured such that, for example, a signal received from the mobile terminal 223 causes the chlorine dioxide generator control device 203 to start operating the chlorine dioxide generator 1e. In addition, the chlorine dioxide generation system 201 may be configured such that, for example, a signal received from the mobile terminal 223 causes the chlorine dioxide generator control device 203 to stop the chlorine dioxide generator 1e. That is, the chlorine dioxide generator control device 203 may be configured to start operating the chlorine dioxide generator 1e or to stop the chlorine dioxide generator 1e in response to a signal received from the mobile terminal 223, without going through the chlorine dioxide generator control device 203.

[0167] Furthermore, while the chlorine dioxide concentration read by the chlorine dioxide concentration measuring sensor 209 is displayed on the monitor unit 215, the system may also be configured to display the chlorine dioxide concentration read by the chlorine dioxide concentration measuring sensor 209 on the mobile terminal 223.

[0168] In addition, in the chlorine dioxide generator 1e, chlorine dioxide may be generated by a chemical reaction by placing the first container 19, the second container 21, the first agent 23, and the second agent 25 into container 3, similar to the chlorine dioxide generator 1.

[0169] Alternatively, chlorine dioxide may be generated using a rod-shaped member erection device 47 equipped with a rod-shaped member 45, as shown in Figure 12, in a manner similar to that shown in Figure 3. Reference numeral 27 in Figure 12 indicates a chlorine dioxide diffusion device.

[0170] The chlorine dioxide diffusion device 27 shown in Figure 12 is configured as shown in Figure 13, comprising a bottomed cylindrical housing 225 and a fan (not shown) located inside the housing 225. As the fan rotates, the chlorine dioxide generated in the chlorine dioxide generator 1e enters the inside of the housing 225 through piping (not shown). Also, as the fan rotates, the chlorine dioxide inside the housing 225 is expelled from the top end of the housing 225 to the outside (room 205).

[0171] Now, let's explain the operation of the chlorine dioxide generation system 201.

[0172] First, the chlorine dioxide generator 1e and the chlorine dioxide generator control device 203 are appropriately installed in the room 205 to be disinfected.

[0173] Next, for example, at night or when no one is entering room 205, the chlorine dioxide generator 1e is started to release chlorine dioxide into room 205.

[0174] Next, when the concentration of chlorine dioxide in room 205 exceeds a predetermined threshold, the operation of the chlorine dioxide generator 1e is stopped.

[0175] Subsequently, the concentration of chlorine dioxide in room 205 will gradually decrease due to natural decomposition over time, and after a predetermined period of time, the concentration of chlorine dioxide will drop to a level safe for humans (for example, 0.1 ppm). The time at which the predetermined period of time has elapsed is, for example, early morning. A person will enter room 205 after the predetermined period of time has elapsed.

[0176] By operating the chlorine dioxide generating system 201 in this manner, it is possible to ensure safety while properly disinfecting room 205 and making effective use of the room.

[0177] The chlorine dioxide generation system 201 comprises a chlorine dioxide generator 1e and a chlorine dioxide generator control unit 211 that stops the operation of the chlorine dioxide generator 1e when the concentration of chlorine dioxide detected by the chlorine dioxide concentration measuring sensor 209 exceeds a predetermined threshold.

[0178] This ensures that the concentration of chlorine dioxide in room 205 is reliably maintained at an appropriate level for disinfection, compared to the case where the chlorine dioxide generator 1e is stopped using a timer.

[0179] Furthermore, by using multiple chlorine dioxide generators 1e, chlorine dioxide can be released quickly and uniformly into room 205. Since there is only one chlorine dioxide generator control device 203 installed in room 205, only one expensive chlorine dioxide concentration measuring sensor 209 is needed, and the chlorine dioxide generation system 201 can be constructed at a low cost.

[0180] In the chlorine dioxide generation system 201, the chlorine dioxide generator control device 203 is configured to start the operation of the chlorine dioxide generator 1e in response to a signal received from the mobile terminal 223. This means that if the chlorine dioxide generation system 201 (chlorine dioxide generator 1e, chlorine dioxide generator control device 203) is installed in room 205, the operation of the chlorine dioxide generator 1e can be started remotely. This reduces the workload required of the room 205 administrator.

[0181] Furthermore, the chlorine dioxide generation system 201 may be equipped with a calendar function that allows it to operate (start and then stop) at predetermined times (for example, on specific days of the week or at specific times) in predetermined cycles. The calendar function shall be provided in the chlorine dioxide generator 1e or the chlorine dioxide generator control device 203, or in both the chlorine dioxide generator 1e and the chlorine dioxide generator control device 203.

[0182] Incidentally, the description of the chlorine dioxide generation system 201 mentioned above can also be understood as a method of releasing chlorine dioxide, which involves separating chlorine dioxide from pure chlorine dioxide water by bubbling and releasing this separated chlorine dioxide into the room to be disinfected.

[0183] The chlorine dioxide release method comprises a chlorine dioxide discharge step in which the discharge of chlorine dioxide into the room is initiated, a chlorine dioxide measurement step in which the concentration of chlorine dioxide in the air inside the room is measured after the discharge of chlorine dioxide in the chlorine dioxide discharge step has started, and a chlorine dioxide stop step in which the discharge of chlorine dioxide into the room is stopped when the concentration of chlorine dioxide detected in the chlorine dioxide measurement step exceeds a predetermined threshold.

[0184] In the chlorine dioxide release method, the separation of chlorine dioxide from pure chlorine dioxide water is carried out at multiple locations within the room. The release of the separated chlorine dioxide is also carried out at multiple locations within the room. These multiple locations within the room are appropriately spaced apart to ensure the chlorine dioxide concentration is as uniform as possible within the room.

[0185] Furthermore, in the chlorine dioxide release method, the measurement of chlorine dioxide at the chlorine dioxide measurement stage is performed at a location appropriately separated from multiple chlorine dioxide release points. For example, in a plan view, it is performed at the center of the multiple chlorine dioxide release points. In the vertical direction, it is performed on the floor of the room, or at a predetermined distance (for example, 0.3m to 3m) above the floor of the room. [Explanation of Symbols]
