    GAS SUPPLY APPARATUS FOR CHLORINE INJECTION SYSTEM}
    [22] The present invention relates to a technology for automatically switching the chlorine gas supply in the chlorine injection equipment installed in the water purification plant, in particular when the chlorine stored in the chlorine container of one pipe is exhausted or the valve of the container is closed to drive the other valve The present invention relates to an automatic gas supply system for a chlorine injection system, which continuously supplies chlorine stored in a chlorine container in a tank.
    [23] In a conventional chlorine injection facility installed in a water purification plant, chlorine is continuously supplied by manually operating valves of chlorine containers respectively connected to two chlorine pipes.
    [24] For example, when the valve of the chlorine container connected to the first pipeline is opened, the liquefied chlorine supplied from it is converted into a gaseous state through a vaporizer, and the chlorine gas is mixed with the dissolved water in the injector, and then the chlorine contact tank It is sprayed to purify.
    [25] Thereafter, the manager checks the remaining amount of chlorine in the chlorine vessel connected to the first pipeline at any time, and closes the valve of the chlorine vessel when the residual quantity falls below a certain value, and continues by opening the valve of the chlorine vessel connected to the second pipeline. Allow chlorine to be fed.
    [26] As described above, in the chlorine injection facility according to the prior art, in order to continue supplying chlorine, the manager has to check the chlorine container replacement time from time to time and manually switch the valve at that time, which makes it difficult to manage. In addition, if the container replacement time has passed by mistake or the valve is incorrectly operated, the supply of chlorine is interrupted, leading to an accident that high-quality tap water is not produced.
    [27] Accordingly, an object of the present invention is to automatically control the electric valve so that when the chlorine stored in the chlorine container connected to one pipeline is exhausted or the valve of the container is closed, the chlorine stored in the chlorine container connected to the other pipeline is continuously supplied automatically. The present invention provides an automatic gas supply device for chlorine injection equipment.

    [28] According to the first aspect of the present invention, the opening and closing of the electric valve is automatically controlled so that the chlorine supply is not interrupted.
    [29] According to the second aspect of the present invention, the remaining amount and pressure of chlorine, the opening and closing state of the electric valve and so on are displayed.
    [30] 1A and 1B are schematic diagrams of an automatic gas supply apparatus for a chlorine injection system according to the present invention, as shown in FIG. 1, in which a first pipe line 11 and a second pipe line 21 are connected in parallel to continuously supply chlorine gas. To the respective chlorine vessels 12A, 12B, and 22A, 22B, and the chlorine supplied from them is mixed with the dissolved water in the injector 38 through the vaporizer 31, the injector 36 and then chlorine. In the chlorine gas supply device that is injected into the diffuser (40) in the contact tank 39 to produce high quality tap water, the remaining amount of chlorine stored in the chlorine containers (12A, 12B, 22A, 22B) Chlorine container weighing scales 13 and 23 for respectively detecting; Pressure sensors (15) and (25) for respectively detecting the pressures of the first pipe line (11) and the second pipe line (21) and outputting a detection signal according thereto; It is provided in parallel to the manual valves 16 and 26 respectively provided on the first pipe line 11 and the second pipe line 21, and closes the pipe line of any one of the pipe lines 11 and 21, respectively. And electric valves and motors (17, 18), (27, 28) for continuously supplying chlorine by opening the other side pipe; A chlorine gas leak detector 41 which detects leakage of chlorine gas and outputs a detection signal accordingly; Control the driving of the electric motors 18 and 28 in accordance with the output signals of the pressure sensors 15 and 25 to selectively open and close the electric valves 17 and 27 and measure the chlorine container weighing scale. On the basis of the output signals of (13) and (23), the remaining gas of each of the chlorine vessels 12A, 12B, and 22A, 22B is displayed by water, and the container replacement time, the standby state of injection, the chlorine gas pressure It comprises a control box 50 for displaying the state, the opening and closing state of the electric valve 17, 27, etc., and will be described in detail with reference to FIGS. 2 and 3 attached to the operation of the present invention configured as described above. Is as follows.
    [31] When the administrator switches the automatic / manual selection switch 56 provided on the panel of the control box 50 to the "manual" side, the chlorine gas exchange mode is set to the manual mode. Subsequently, the manager switches the first pipeline opening / closing switch 57 or the second pipeline opening / closing switch 58, for example, the first pipeline opening / closing switch 57 in the “open” direction.
    [32] At this time, the controller (PLC) 50A embedded in the control box 50 recognizes that the automatic / manual selection switch 56 is switched to the "manual" terminal, and then displays the automatic / manual indicator 56A on the panel. "Manual" is displayed. Subsequently, the controller 50A drives the electric motor 18 so that the electric valve 17 installed in the first conduit 11 starts to open, and the electric valve 17 is fully opened to open its limit switch. When 17A is shorted, the driving of the electric motor 18 is stopped. The controller 50A then displays “open” on the first conduit indicator 57A on the panel, “close” on the second conduit indicator 58A, and opens the valve for the motorized valve 17. The indicator 55A1 is turned on, and the valve closing indicator 55B2 for the electric valve 27 is turned on, and the input standby indicator 53B provided at the corresponding position of the chlorine container indicator is turned on.
    [33] Accordingly, the liquid chlorine stored in the chlorine containers 12A and 12B is converted into the gas state in the vaporizer 31 through the electric valve 17, and then the pollutant is filtered through the gas filter 33. , And is delivered to the injector 38 through the vacuum regulator 35 and the injector 36. Here, the vacuum regulator 35 and the injector 36 are installed to adjust the vacuum state of the pipe and the chlorine input amount.
    [34] The chlorine gas supplied to the injector 38 through the above path is mixed with the dissolved water supplied by the dissolved water pumps 37A and 37B, and then through the diffuser device 40 mounted on the chlorine contacting tank 39. It is sprayed to produce quality tap water.
    [35] Meanwhile, the chlorine container weighing scale 13 measures the remaining weight of chlorine stored in the chlorine container 12A and outputs a signal according to the chlorine container 12A and 12B. The chlorine container 12A and 12B are connected to each other by the first pipe line 11. They are penetrated and placed under the same pressure, so that their residual chlorine is the same, so only the remaining weight of one container needs to be measured.
    [36] Looking at the internal action of the chlorine container weighing scale 13, the residual weight measurement signal measured by the load cell 13A is transmitted to the transmitter 13C through the indicator 13B is converted into a predetermined transmission format and then the control box The weighing scale indicator 51A of 50 is transmitted. Accordingly, the weighing scale indicator 51A displays the remaining amount of chlorine in the current chlorine containers 12A and 12B as a number based on the remaining amount weighing signal transmitted. Herein, the indicator 13B displays the remaining amount of chlorine in the chlorine containers 12A and 12B based on the remaining amount weighing signal measured by the load cell 13A, and alerts when the remaining amount falls below a certain value. Output
    [37] At this time, the chlorine container weighing scale 23 on the second pipe 21 side also operates in the same way as the weighing scale 13 on the first pipe 11 side, and the weighing scale indicator 51B measures the weighing scale 13. ), The remaining amount of chlorine in the chlorine containers 22A and 22B is indicated by the number.
    [38] Separately, the pressure sensor 15 detects the pressure of the first conduit 11, and if the pressure of the first conduit 11 is maintained at a predetermined value or more, the limit switch 15A of the pressure sensor 15. Is opened, and the controller 50A recognizes the state to turn off the low pressure indicator 54A on the panel.
    [39] Thereafter, when the chlorine remaining in the chlorine vessels 12A and 12B drops below a predetermined value, the limit switch 15A of the pressure sensor 15 is shorted, and the controller 50A is connected to the limit switch (A). Recognizing that 15A) is shorted, the low pressure indicator 54A on the panel is turned on, and the container replacement indicator 52A is turned on to allow the administrator to take action.
    [40] Accordingly, the manager switches the first pipeline opening / closing switch 57 in the "closed" direction and the second pipeline opening / closing switch 58 in the "open" direction. At this time, the controller 50A recognizes that the on / off switches 57 and 58 are switched, and then drives the motor 28 to open the electric valve 27 installed in the second conduit 21. Starts and stops the drive of the electric motor 28 when the electric valve 27 is fully open and its open limit switch 27A is short-circuited. Therefore, from this time, the liquid chlorine stored in the chlorine containers 22A and 22B starts to be supplied.
    [41] In addition, the controller 50A drives the electric motor 18 in the opposite direction, and the electric valve 17 installed in the first conduit 11 starts to close, and the electric valve 17 is completely closed. When the closing limit switch 17B is shorted, the drive of the electric motor 18 is stopped. The controller 50A then displays "closed" on the first conduit indicator 57A on the panel, "open" on the second conduit indicator 58A, and closes the valve for the motorized valve 17. The indicator 55A2 is turned on and the valve opening indicator 55B1 with respect to the electric valve 27 is turned on.
    [42] On the other hand, when the administrator switches the automatic / manual selection switch 56 provided on the panel of the control box 50 to the "auto" side, the chlorine gas exchange mode is set to the automatic mode. At this time, the controller 50A recognizes that the auto / manual selection switch 56 is switched to the “auto” terminal and displays “auto” on the auto / manual indicator 56A on the panel.
    [43] When the automatic mode is set as described above, the controller 50A recognizes that the limit switches 15A, 25A of the pressure sensors 15, 25 are short-circuited and the electric motors 18, 28 as described above. By driving the one of the electric valves 17, 27 of the electric valve is opened and the other electric valve is closed, the chlorine supply is automatically switched.
    [44] In addition, the lighting control operation of each of the indicators and the operation of each part is performed in the same manner as in the manual mode.
    [45] On the other hand, a chlorine gas sensor (SEN1-SEN3) is provided in each part where the chlorine injection facility is installed. Therefore, when chlorine gas leaks in the automatic mode or the manual mode, chlorine gas is detected by at least one of the chlorine gas sensors SEN1-SEN3, and the alarm switch 41A of the chlorine gas leak detector 41 is short-circuited. .
    [46] At this time, the controller 50A recognizes that the alarm switch 41A is short-circuited and then drives the motors 18 and 28 to close all the electric valves 17 and 27 and to alarm. It generates a sound and outputs an alarm message on the display device (not shown), so that the administrator can recognize the fact and take necessary action. At the same time, the controller 50A drives a chlorine gas removal facility (not shown) to remove the leaked chlorine gas.
    [47] Thereafter, when the administrator presses the reset switch 59, the controller 50A recognizes that the reset switch 59 is shorted and causes the system state to return to the original state.
    [48] As described in detail above, the present invention automatically opens and closes the valve so that the chlorine stored in the chlorine container connected to the other pipeline is continuously supplied when all the chlorine stored in the chlorine container connected to the one pipeline is exhausted or the valve of the container is closed. By doing so, there is an effect that can provide convenience in management. In addition, there is an effect that can prevent the chlorine gas supply is stopped due to the management of the manager.
