[0103] "Structure of Chlorine Dioxide Gas Generation System"

[0104] figure 1 It is a side view showing a schematic configuration of a chlorine dioxide gas generating system (hereinafter also simply referred to as a gas generating system) 100 according to the first embodiment. figure 2 It is a plan view which shows the schematic structure of the chlorine dioxide gas generation system 100 of 1st Embodiment.

[0105] The gas generating system 100 of the first embodiment includes a chlorine dioxide gas generating device (hereinafter also simply referred to as a gas generating device) 2, a humidifier 3, a fan 4, and a chlorine dioxide gas decomposing device (hereinafter referred to as a gas generating device) in a box-shaped box 1. Also referred to simply as gas decomposition device) 5 and control device 6. The gas generating system 100 is arranged on the outside of the wall 71 of the sterilization chamber 7 as a closed space requiring fumigation, sucks the air in the steriliz...

[0146] Figure 11 It is a figure which shows and explains the structure of the humidity sensor 9 of 2nd Embodiment. In the second embodiment, the humidity sensor 9 is provided in the sampling tube 91 , and the sampling tube can be freely opened and closed by the electromagnetic valve 92 provided on the sampling tube 91 . The sampling tube 91 and the solenoid valve 92 are equivalent to the isolating means of the present invention. Furthermore, the humidity sensor 9 is connected to the control device 6 via a cable. In addition, the humidity sensor 9 can also be connected with the humidity sensor display recorder. In addition, the suction pump 93 is connected to the base end of the sampling tube 91 and can suck the air in the sterilization chamber 7 into the sampling tube 91 . Exhaust from the suction pump 93 can be discharged into the sterilization chamber 7 . Furthermore, by electrically connecting the solenoid valve 92 and the suction pump 93 to the control device 6 , the ...

[0152] The operation in step S03 can be performed as follows. Specifically, the CPU may operate the heater 22 after a predetermined time elapses after the nozzle 29 is opened to supply the acidic liquid stored in the tank 24 to the container 23 . The specified time can be determined according to the shape and size of the sodium chlorite. For example, in the case of reacting granular sodium chlorite and an acidic liquid, about 10 minutes can be adopted for the predetermined time.

[0153] For example, when the room temperature of the sterilizing chamber 7 is in the range of 20°C to 30°C, the concentration of chlorine dioxide gas after mixing the powdered sodium chlorite that has not formed particles and the acidic liquid will reach 100% in a few minutes. 200ppm around half of the peak. On the other hand, it was confirmed that in the reaction between granular sodium chlorite and acidic liquid, the concentration of chlorine dioxide gas was a safe concentration for managers and ...

Abstract

The invention provides a chlorine dioxide gas generation system and a chlorine dioxide gas decomposer, i.e., provides a technology which can generate chlorine dioxide gas and enable the chlorine dioxide gas to be decomposed with shorter time than before. The chloride dioxide gas generation system includes a chlorine dioxide gas generation device which generates chlorine dioxide gas and a chlorine dioxide gas decomposer which inhales and decomposes residual gas of chlorine dioxide gas delivered to indoors from the chlorine dioxide gas generation device, and the chlorine dioxide gas decomposer contains filter material, and the filter material contains at least any one of manganese oxide and permanganate.

Description

technical field [0001] The invention relates to a chlorine dioxide gas generation system and a chlorine dioxide gas decomposition device. Background technique [0002] There are techniques for killing microorganisms and microscopic insects such as gnats (chatatemushi) using chlorine dioxide gas. When chlorine dioxide gas comes into contact with protein in microbial cells, it generates oxygen radicals, oxidizes the protein, and reacts with sodium in microorganisms to produce NaCl. Chlorine dioxide gas reacts if it comes in contact with the protein. [0003] (chemical 1) [0004] ClO 2 + Na of protein → oxidized protein + NaCl [0005] Compared with other chlorine, sodium hypochlorite, and hydrogen peroxide, chlorine dioxide gas is less toxic to the human body, so it can be more safely sterilized and sterilized. In addition, chlorine dioxide gas has the following advantages: when the safe concentration is 0.1ppm or less, it has no pungent smell compared with ozone and for...
