The technical field to which the invention belongs 3 The field of the invention The invention relates to an electronic part, etc. In the manufacturing process, an ozone water supply device for supplying ozone water used for cleaning or stripping of a resist, etc., and in particular, relates to an ozone water supply device capable of intermittently supplying ozone water. [Prior Art 3 Background 10] In the past, ozone water was used for wet cleaning of electronic parts and resist stripping of lithographic imaging steps, and it was made by dissolving ozone in ultrapure water in an ozone water production device. Manufacturing. The known conventional ozone water supply device is disclosed in Japanese Patent Laid-Open Publication No. 7-185572, and its structure is shown in Fig. 3. 15 As shown in the figure, in the ozone water supply device, the ozone supply pipe 52 and the water supply pipe 54 are connected to the ejector 50. The water flow from the water supply pipe 54 to the ejector 50 is used, and the ozone generated by the ozone generator 56 passes through. The ozone supply pipe 52 is sucked into the ejector 50 and mixed with ultrapure water to generate ozone water. This ozone water system is supplied to the gas-liquid separation device 58, and after the undissolved 20 ozone is separated, it is supplied to the point of use through the ozone water supply pipe 60. The gas-liquid separation device 58 is provided with a concentration meter 62 for measuring the ozone concentration of the ozone water, and the ozone water supply pipe 60 is provided with a flow meter 64 for measuring the ozone water flow rate, and the control device 66 is based on the concentration meter 62 and the flow rate. Based on the detection result of 64, the voltage of the ozone generator 56 is adjusted by the voltage regulator 68, and the voltage of the invention is explained. However, even if the voltage of the ozone generator 56 is changed by the above-mentioned ozone water supply device, the amount of ozone sucked by the ejector 50 does not change immediately, so there is a problem that the traceability of the ozone water concentration is not good. Therefore, when it is necessary to supply ozone water intermittently, it takes a long time to wait for the ozone water to stabilize to the desired concentration shortly after the start of supply (5 to 6 minutes according to the above bulletin). This period will not only be wasted Discarded ozone water has problems such as loss of process time. When ozone water is used at a plurality of use points, when the ozone supply pipe 5 is separated and ozone water is produced at each use point, the change in the voltage of the ozone generator 56 affects the ozone flow rate at all the use points. Therefore, it is difficult to individually control the concentration of ozone water at each use point. On the other hand, if it is configured to separate the ozone water supply pipe 60 and lead it to each point of use, the transfer distance of the ozone water supply pipe 60 will inevitably become longer (for example, 20 to 100 m), so there is 15 dissolved ozone. During the transfer, self-decomposition may occur and the ozone concentration may decrease. Therefore, in the past, it was necessary to install an ozone generating device near each use point, and the equipment cost was high and there were problems in maintenance. [Summary of the Invention] Disclosure of the Invention 20 The present invention was made to solve the above problems, and an object thereof is to provide an ozone water supply device that can economically and efficiently intermittently supply ozone water of a desired concentration. The foregoing object of the present invention is achieved by an ozone water supply device, and the ozone water supply device has: an ejector connected to pure water 6 1225038 玖, an introduction pipe of the invention and an ozone introduction pipe, and passing through the foregoing The water flow of pure water introduced by the pure water introduction pipe passes through the aforementioned ozone introduction pipe to attract those who mix ozone; and an ozone water supply pipe which supplies the ozone water generated by the aforementioned ejector to the point of use; and, the ozone introduction The pipe is provided with a flow rate 5 adjusting mechanism, and the aforementioned ozone water supply pipe is provided with a concentration detector for detecting the concentration of ozone water, and has a control mechanism for adjusting the opening degree of the aforementioned flow adjusting mechanism according to the detection of the aforementioned concentration detector. The foregoing control mechanism should preferably increase the opening of the flow adjustment mechanism when the detection concentration of the concentration detector is lower than the predetermined concentration, and reduce the flow adjustment mechanism when the detection concentration of the concentration 10 detector is higher than the predetermined concentration. Opening degree. One end of the ozone introduction pipe is connected to an ozone generating device, and the other end is connected to a plurality of ejectors through a plurality of distribution pipes. At this time, 'the aforementioned concentration detectors should be respectively provided in the aforementioned 15 ozone water supply pipes connected to the aforementioned ejectors. Moreover, the aforementioned control mechanism should adjust the opening degree of the aforementioned flow rate adjustment mechanism corresponding to the detection by the aforementioned density detector. Brief Description of the Drawings Fig. 1 is a block diagram showing a schematic configuration of an ozone water supply device according to an embodiment of the present invention. 20 Fig. 2 is a block diagram showing an application example of the ozone water supply device shown in Fig. 1. Fig. 3 is a block diagram showing a schematic structure of a conventional ozone water supply device. 7 1225038 发明 Description of the Invention L Embodiment 3 Best Mode for Implementing the Invention Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Fig. 1 is a block diagram showing the outline 5 of an ozone water supply device according to an embodiment of the present invention. As shown in the figure, the ozone water supply device 1 includes an ejector 2 and a gas-liquid separation device 3. The ejector 2 is composed of a pure water introduction pipe 12 and an ozone introduction pipe 13. When the pure water introduced by the pure water introduction pipe 12 is sprayed from a nozzle (not shown), the water flow is attracted by the ozone introduction pipe 13 Introduce ozone and mix 10 internally. The introduced pure water and ozone can be produced by a known pure water producing device and an ozone generating device, respectively. A pure water production device can be used, such as a reverse osmosis pure water production device, and a filter element having an ion exchange resin or the like can be used to produce high purity ultrapure water. In addition, the ozone generating device can be exemplified by an electrolytic ozone generating device that electrolyzes pure water and generates high-concentration ozone. The ozone generating device should have a pressure regulating valve capable of fixing the supply pressure on the primary side and a treatment device. Exhaust ozone decomposer with excess ozone. The discharge side of the ejector 2 is connected to the gas-liquid separation device 3 through the mixing pipe 4, and pure water and ozone mixed by the ejector 2 are introduced into the gas-liquid separation device 3 through the mixing pipe 4. 20 The gas-liquid separation device 3 is connected to an ozone exhaust pipe 14 and an ozone water supply pipe 5, and the ozone exhaust pipe 14 is connected to an ozone decomposer 15 filled with an ozone decomposing catalyst. Excess ozone that has not been dissolved in the pure water introduced into the gas-liquid separation device 3 through the mixing pipe 4 is transferred to the ozone decomposer 15 through the ozone discharge pipe 14 to be decomposed into oxygen, and only ozone water can pass through the ozone water supply pipe 5 Supply 8 1225038 发明, description of the invention to the point of use. Moreover, the gas-liquid separation device can also be known, for example, a swirling type that separates ozone water from ozone by using centrifugal force, a seeding type that allows gas-liquid two-phase flow to collide with a baffle plate, or a barbed wire Liquid-separating foam type and so on. 5 The pure water introduction pipe 12, the ozone water supply pipe 5, and the ozone discharge pipe 14 are respectively provided with a pure water supply valve 21, an ozone water supply valve 22, and an ozone discharge valve 23, and these open relationships pass through the control device 30 To control. A dissolved ozone monitor 24 is provided in the ozone water supply pipe 5, and the ozone introduction pipe 13 includes a flow rate adjustment mechanism 25. The dissolved ozone monitor 10 is a concentration detector for detecting the ozone concentration of the passing ozone water, and outputs the detection result to the control device 30. The dissolved ozone monitor 24 should be a linear type with good response characteristics, but it can also be used by modifying the reaction time even if it is a pumping type. The flow rate adjusting mechanism 25 is composed of, for example, a variable distribution valve which can continuously change the opening degree of the ozone introduction pipe 13, and adjusts the opening degree by controlling the device 30. Next, the operation of the ozone water supply device having the above structure will be described. When supplying ozone water, ozone and pure water are introduced into the ejector 2 when any one of the pure water supply valve 21, the ozone water supply valve 22, and the ozone discharge valve 23 is open. The pure water introduced into the ejector 2 should be highly purified ultrapure water 20. The supply pressure of the ozone generator (not shown) that supplies ozone to the ozone introduction pipe 13 is preferably in the range of 0.1 to 0.3 MPaG. The ozone and pure water introduced into the ejector 2 become fully mixed ozone water during the passage of the ejector 2 and the mixing pipe 4, and after the excess ozone is removed by the gas-liquid separation device 3, the ozone is supplied through the ozone water supply pipe 5 Water 9 1225038 发明, description of the invention. The concentration of the supplied ozone water can be constantly detected by the dissolved ozone monitor 24 and input to the control device 30. When the ozone water concentration is higher than the desired concentration, the control device 30 reduces the opening degree of the flow rate adjustment mechanism 25 and reduces the 5 flow rate of the ozone introduced into the ejector 2. In addition, when the ozone water concentration is lower than the desired concentration At this time, the opening degree of the flow rate adjustment mechanism 25 is enlarged, and the flow rate of ozone introduced into the ejector 2 is increased. As a result, even if the supply amount of ozone water is changed, the concentration of ozone water can be maintained at a substantially desired value. During the intermittent supply of ozone water, etc., when the ozone water stop signal is input to the control device 30, the control device 30 closes the pure water supply valve 21 and the ozone discharge valve 23, and stops the supply of ozone water. In addition, since the introduction of ozone to the ejector 2 is performed by the attraction force accompanying the water flow, when the pure water supply valve 21 is closed and the flow of pure water to be introduced into the ejector 2 is not present, the ozone to the ejector 2 is not present. The import also stopped. Furthermore, by closing the ozone discharge valve 23, the ozone remaining in the gas-liquid separation device 3 can be prevented from leaking to the outside. As a result, pure water and ozone are not wasted, and the supply of ozone water can be stopped. In addition, when the supply of ozone water is stopped, when excessive ozone is generated in the ozone generated by the ozone generating device, decomposition can be performed by the aforementioned exhaust ozone decomposer (not shown) provided with the ozone generating device, and the decomposition is stopped. After the supply of the ozone water request signal is input to the control device 30 after the supply within a predetermined period, the control device 30 makes the pure water supply valve 21 and the ozone discharge valve 23 open and restarts the supply of pure water to the ejector 2. As a result, a pure water flow will be generated in the ejector 2 and at the same time, the ozone will be attracted. The concentration of the ozone water supplied from the ozone water supply pipe 5 will be a little unstable soon after the supply is started again, but the control device 30 can adjust the opening degree of the flow adjustment mechanism 25 according to the detection of the dissolved ozone monitor 24 to maintain the desired Value. Therefore, shortly after the start of the supply of ozone water, ozone water of a desired concentration can be supplied, and the ozone water need not be wasted. The switches of the pure water supply valve 21 and the ozone discharge width 23 controlled by the control device 30 and the opening degree adjustment of the flow adjustment mechanism 25 are performed repeatedly during the intermittent supply of ozone water. When using ozone water at most use points, as shown in Figure 2, the structure 10 separates the ozone introduction pipe 13 connected to one ozone generating device 40, and then the distribution pipes 13a, 13b, 13c, and 13d separate Ozone guidance near each point of use. Each of the distribution pipes 13a to 13d is provided with a flow rate adjustment mechanism 25. In addition, the ejector 2, the gas-liquid separation device 3, the ozone water supply pipe 5, the pure water introduction pipe 12, and the control device 30 are also provided at each use point, and the control device 15 30 is based on the detection of the dissolved ozone monitor 24 , Adjust the opening degree of the flow adjustment mechanism 25 of the distribution pipes 13a to 13d corresponding to the use points. With these structures, even if there is one ozone source, the concentration of ozone water can be individually controlled at a plurality of individual use points, which can reduce equipment costs and facilitate maintenance. In addition, because ozone water can be transferred to various use points before producing ozone water, it is not necessary to carry out long-distance transfer in the state of ozone water, and the ozone in the transfer will be naturally decomposed, and the concentration of ozone water can be prevented from decreasing. Problem. In particular, when ultra-pure water containing organic matter is decomposed by ultraviolet rays with a short wavelength (185 nm), the effect of using such a structured ozone water supply device is more obvious. 11 1225038 (2) In the structure shown in the second embodiment of the invention, the ozone generating device is an electrolytic ozone generating device that uses electrolytic decomposition of pure water to generate high-concentration ozone, and the maximum amount of ozone generated is 48 g. / h 者. In addition, the pressure of the ozone is controlled to be constantly maintained at 0.1 MPaG, and the concentration of ozone generated is 230 g / m3, and is distributed equally to each ozone through the distribution pipes 13a to 13d where the ozone introduction pipe 13 diverges. Supplying device 1. The ozone introduction pipe 13 and the distribution pipes 13a to 13d are fluorine resin pipes with an inner diameter of 4 mm and an outer diameter of 6 mm. The ozone flow paths from the ozone generating device 40 to each use point are made 40m, 10 60m, 70m, and 80m. In addition, in each ozone water supply device 1, the flow rate of pure water introduced into the ozone water production device 2 through the pure water introduction pipe 12 is set such that the ozone water supplied by the ozone water supply pipe 4 has a flow rate of 2.5 L / in a steady state. Min, concentration 20ppm. The gas-liquid separation device 3 uses a cyclone type, and the flow rate adjustment mechanism uses a variable flow valve. Dissolved ozone monitors 24 15 are screened dissolved ozone monitors. Under this condition, the pure water supply valve 21, the ozone water supply valve 22, and the ozone discharge valve 23 are opened, and the supply of ozone water is started. When the concentration of the ozone water supplied from the ozone water supply pipe 5 is measured at the point of use farthest from the ozone generating device 40, it is as shown in Table 1 below. 12 20 1225038 发明, description of the invention Table 1 Ozone water concentration (ppm) At the beginning of supply 0 5 seconds later 16 10 seconds later 19 20 seconds later 21 30 seconds later 20

Value (20 5 ppm). As the ozone water concentration approaches the desired value, the control device 30 will gradually reduce the opening degree of the flow rate adjustment mechanism 25, whereby the ozone water concentration will be maintained at a roughly desired value afterwards. This result is the same as that of other use points. Industrial Applicability 10 According to the ozone water supply device of the present invention, ozone water of a desired concentration can be supplied shortly after the start of the supply of ozone water. Therefore, when the ozone water is intermittently supplied, the ozone after the waste supply is started can be prevented. The waste of water can also solve the waiting time for the concentration of ozone water to stabilize. 13 15 1225038 发明 Description of the invention [Brief description of the drawings] Fig. 1 is a block diagram showing a schematic structure of an ozone water supply device according to an embodiment of the present invention.
