[Industrial Application Field] This invention relates to a mercury ozone lamp used for sterilization inside a pop-type beverage vending machine, and in particular, it is capable of always stably generating ozone within a predetermined range regardless of fluctuations in outside temperature. , which can be immediately adapted to vending machines of various capacities. [Prior art] The use of mercury ozone lamps for sterilization has been known for a long time in refrigerators, etc., and for example, Japanese Patent Publication No. 13169/1983 also describes the use of mercury ozone lamps for sterilization of dry sausages. This document states that the amount of ozone generated is not constant because it varies depending on the volume of the processing drying room for dry sausages, and it also states that the amount of ozone generated is not constant because it varies depending on the volume of the processing drying room for dry sausages. According to a flyer distributed by Sankyo Kako Co., Ltd. located in -4, a cleaner equipped with a mercury ozone lamp is introduced for disinfecting inside vending machines. [Problems to be solved by the invention] As mentioned above, it is known that mercury ozone lamps can be used for sterilizing inside pop-type beverage vending machines and that the ozone concentration of the sterilizing air needs to be at least 0.03 PPM. However, the important performance of mercury ozone lamps and the environment in which they are used have not been elucidated. This invention has solved these remaining problems and has developed a mercury ozone lamp that can always generate the optimum amount of ozone regardless of changes in outside temperature and can be easily adapted to vending machines of various capacities. The purpose is to obtain. [Means for Solving the Problems] In the case of this invention, a hot cathode straight tube type quartz low pressure mercury ozone lamp is used, and the coldest point temperature on the surface of the quartz lamp when the lamp is lit is 50 to 100 degrees Celsius in a windless state with an air temperature of 20 degrees Celsius. In addition, the amount of ozone emitted in this state is selected to be 2 to 10 mg per hour, and this is used as the mercury ozone lamp of the first invention, and furthermore, the outer surface of this mercury ozone lamp is Covering wall thickness 20~
A tube-equipped mercury ozone lamp of the second invention is constructed by covering the outer tube with a 300 μm fluororesin outer tube. [Function] In the case of this invention, since the above-mentioned coldest point temperature of the mercury ozone lamp is set as described above, it is possible to always stably generate ozone within a predetermined range regardless of fluctuations in the outside temperature. Furthermore, by selecting the thickness of the outer tube that covers the outer surface of the mercury ozone lamp, a common mercury ozone lamp can be used as is for vending machines of various sizes with different capacities. [Example] The current upper limit of ozone concentration is the Environmental Agency standard value.
0.06PPM, or the effort environment standard value announced by the Ministry of Labor is 0.1PPM in one hour, and the lower this value is, the better. In addition, in the conventional pop-type beverage vending machines currently in use, it is appropriate to set the amount of air blown out for sterilization in the range of 0.3 to 0.6 m 3 /min, and if the amount of air is insufficient, If the amount is too large and does not reach all parts, there is a risk of increasing the ozone concentration around the vending machine. Therefore, the ozone concentration should be adjusted within the above air supply amount range.
The amount of ozone generated to keep it within the range of 0.03 to 0.1 PPM is calculated from the molecular weight value of ozone of 48 to be 1.2 to 8 mg per hour. In reality, some ozone loss or natural extinction occurs, so the appropriate amount of ozone generated from a mercury ozone lamp is 2 to 10 mg per hour. On the other hand, mercury ozone lamps have the property that the intensity of the ultraviolet rays they emit is significantly affected by the ambient temperature.
Furthermore, the radiation of ozone rays reaches its maximum when the temperature of the coldest point on the surface of the quartz lamp (hereinafter referred to as tube wall temperature) is 60 to 70°C. This invention optimally sets the range of structural dimensions and operating characteristics of the above-mentioned quartz lamp used in consideration of the above conditions, and FIG. 1 shows a hot cathode straight tube type quartz low-pressure mercury ozone lamp according to the invention, and in the figure, 1 is a quartz lamp, 2 is a filament sealed at both ends, 3 is a base provided at both ends, and 6 is a sealing part at both ends. Specifically, the outer diameter D of the quartz lamp 1 is 15
mmφ, the distance l between the sealed inner end of the filament and its tip is set to 8 mm, and the distance L between the sealed inner ends of the filament is set to 46 mm, and when the lighting is performed using the lighting circuit shown in Figure 2. The electrical characteristics and ozone generation data are shown in Table 1 below. In addition, G in FIG. 2 indicates the FG-7E glow starter, and C indicates the yoke for FL-6. By the way, the amount of ozone generated at this time was measured by lighting a mercury ozone lamp inside a sealed stainless steel box, and calculating the increase in the internal ozone concentration using an ozone concentration meter using the potassium iodide method. This is what I did.

By doing this, the inner end of the quartz lamp is heated by the above-mentioned filament placed close to it and becomes hotter than the center, so the mercury inside the quartz lamp does not condense at the inner end, and the excess mercury that does not vaporize is The entire amount of mercury condenses concentrated at the coldest point in the center, and the internal mercury saturated vapor pressure is regulated by the temperature of this coldest point, so the radiation intensity of ozone rays is also uniquely determined by this temperature. become. In addition, the temperature rise value of this coldest point temperature is generally the ratio of the power consumption of the lamp to its surface area (commonly known as surface load).
It is determined by , and as this ratio increases, the temperature rise value also increases. By the way, in a mercury ozone lamp that has a hot cathode type filament at both ends, when the lamp current is constant, as the lamp length becomes shorter, the lamp surface area decreases in proportion, but the reduction in lamp power consumption is less than the reduction in surface area. The above surface load increases. The reason for this is that the energy required for the discharge arc between both filaments decreases in proportion to the filament spacing, but the energy required to adjust the filament itself remains constant regardless of the length of the lamp. Due to the inherent properties of It is for the above reason that the distance between both filaments is made particularly close in order to make the tube wall temperature increase value at least 50° C. in the mercury ozone lamp of the first invention. However, in this case as well, if the distance l between the tip of the filament and its sealed inner end is greater than the above 10 mm, the heating effect of the filament will be difficult to reach the inner end, and the coldest point will shift from the center to the end. do. In this case, even if the power consumption of the lamp is increased and the surface load is increased, the temperature of the center part in contact with the discharge arc will rise, but the temperature of the end part will not rise, so the mercury vapor pressure will not increase, and as a result, ozone radiation will be emitted. There is no increase in strength. The structural dimensions of the quartz lamp in the mercury ozone lamp of the first invention are designed in consideration of the above. FIG. 3 shows the relationship between the tube wall temperature and the ozone radiation output when the mercury ozone lamp of the first invention is turned on, and this measurement was carried out at wavelengths from 140 to
A cesium iodide phototube having spectral sensitivity only in the 200 nm range was used and the ambient temperature of a mercury ozone lamp was varied. As can be seen from this figure, when the tube wall temperature is between 50 and 100℃, the ozone radiation intensity does not fluctuate.
It is within 10%, and its maximum value exists around 70°C. Figure 4 is a graph showing the correlation between the ambient temperature and tube wall temperature of the mercury ozone lamp in the above measurement.The tube wall temperature also increases as the ambient temperature rises, but the temperature difference between the two (tube wall temperature The rise value) is approximately constant at about 50℃. Therefore, in this case, even if the outside temperature fluctuates by 20°C above and below 20°C, the range of change in tube wall temperature will be between 50°C and 90°C, and the change in ozone radiation intensity during this period will be 5%.
It is clear from FIG. 3 above that this is limited to a certain extent. For these reasons, in actual use, mercury ozone lamps are cooled to some extent by supplied air, etc., but the tube wall temperature must be selected and set between 50℃ and 100℃ depending on the environmental conditions at the time. If this is done, a mercury ozone lamp with high efficiency and little fluctuation in the ozone concentration generated will be obtained. However, the tube wall temperature is 100
If the temperature exceeds this temperature, the adhesive for fixing the cap will start to deteriorate, so it is appropriate to keep the upper limit temperature below that temperature. Next, a tube-equipped mercury ozone lamp, which is the second invention of the present invention, will be explained. In order to adjust the ozone supply amount depending on the capacity of the pop-type beverage vending machine and the number of ozone air supply locations,
In conventional equipment, it is necessary to prepare in advance a combination of multiple types of mercury ozone lamps and ballasts, but in order to eliminate this complexity, we used a material such as perbroloalkyl vinyl, which absorbs ozone rays moderately, on the outer surface of the quartz lamp. Mercury ozone with a tube, which is the second invention of the present invention, is covered with a tube made of a fluororesin made of a copolymer of ether and tetrafluoroethylene, so that the radiation output of the ozone beam can be adjusted as desired. The light is shown in Figure 5. That is, in Fig. 5, the same parts as those in Fig. 1 are indicated by the same reference numerals, and the repeated explanation thereof will be omitted, but the tube-equipped mercury ozone lamp of this second invention transmits ultraviolet rays with a wavelength of 185 nm. The above-mentioned fluororesin jacket tube 4 having a wall thickness of 20 to 300 μm is provided so as to cover the space between the base 3 at both ends, and a heat insulation gap 5 is formed between it and the quartz lamp 1. The lamp is characterized in that it is fixed to the cap 3 by heat shrinkage, and the configuration and electrical characteristics of the mercury ozone lamp are exactly the same as those shown in FIG. 1. FIG. 6 shows the relationship between the thickness of the jacket tube 4 and the ozone beam relative output. As can be seen from this figure, by changing the wall thickness of the jacket tube 4 in the range of 20 to 300 μm, ozone Line output is 80~
It is possible to reduce it to 10%. A feature of this envelope tube is that it is extremely less susceptible to deterioration due to ozone rays, making it suitable for long-term use. From the above, by using the tube-equipped mercury ozone lamp of the second invention for sterilization, it can be easily applied to various capacity pot-type beverage vending machines without changing the mercury ozone lamp or ballast. This also simplifies inventory management of mercury ozone lamps and ballasts used in combination with them. [Effects of the Invention] Since the ozone lamp device of the present invention uses the mercury ozone lamp configured as described above, it is possible to always produce ozone within a predetermined range regardless of the installation environment of the ozone lamp device or fluctuations in outside temperature. This has the advantage that it can be produced and supplied stably, that it can be immediately adapted to vending machines of various capacities, and that inventory management of the necessary parts to be prepared is also facilitated.
