Constant chlorine injection device capable of remote control

The present invention relates to a constant chlorine input device capable of remote control, and more specifically, to calculate the amount of chlorine in accordance with the residual chlorine concentration of the raw water, and to drive the metering pump according to the residual chlorine concentration of the output water and the chlorine level of the chlorine tank By controlling the, to reduce the error between the residual chlorine concentration and the set residual chlorine concentration of the water supply to provide a higher quality water supply and chlorine dosing device that is easy to manage according to the re-injection of chlorine.

In general, the constant residual chlorine concentration is maintained at 0.1 ppm to 4 ppm in the faucet. Disposable chlorine in the water supply is disinfected due to a long distance to the water supply line of the water supply facility or a shortage of water supply, which results in a long residence time in the water supply pipe and foreign substances accumulate inside the water supply pipe. There was a problem that the effect is reduced. In order to solve this problem, a high concentration of chlorine is added to the water supply facility to solve the loss of residual chlorine on the average, but this increases the concentration of residual chlorine in the faucet, which increases the disinfection odor and increases the use of water supply. There was a problem that turned off.

Conventionally, in order to solve the above-mentioned problem, chlorine is additionally added to a supply process such as a drainage to secure disinfection of raw water. Conventionally, the introduction of chlorine is made by measuring the residual chlorine concentration of water obtained and then adjusting the residual chlorine concentration set according to the flow rate using a metering pump. However, the conventional chlorine supply device has a problem that it is difficult to control the residual chlorine concentration because the metering pump continues to operate even when the chemical supplied to the metering pump is insufficient or the chlorine effluent concentration is abnormal. In addition, it is difficult to compensate for the residual chlorine concentration difference between the set residual chlorine concentration and the residual chlorine concentration in the output water, because the residual chlorine concentration of the output water which can be changed according to the condition of the sensor, flow meter, and metering pump, etc., which measures the residual chlorine concentration of the incoming water cannot be compensated for. There is this.

The present invention is to solve the above-mentioned conventional problems, and by supplying a higher quality water supply by reducing the error of the residual chlorine concentration and the set residual chlorine concentration of the effluent by adjusting the chlorine input flow rate according to the average residual chlorine concentration of the effluent. It is an object to provide a chlorine dosing device for.

In addition, the present invention is to automatically control the operation of the metering pump in accordance with the average residual chlorine concentration of the effluent and the chlorine level of the chlorine tank to efficiently control the chlorine input to the chlorine input device can be remotely controlled in the water supply line Even if several chlorine injection devices are installed, there is another purpose to effectively manage the concentration by controlling the concentration and the like remotely.

Constant chlorine injection device capable of remote control according to the present invention is the following claims.

According to the constant chlorine input device capable of remote control according to the present invention, the residual chlorine concentration of the effluent is reflected to the input amount of chlorine to adjust the residual chlorine concentration of the effluent to approximate the set concentration. It has the effect of providing water supply.

In addition, there is an effect of reducing the residual chlorine concentration measurement error of the discharged water measured at the point of 20 meters (m) to 30 meters (m) away from the water outlet.

In addition, the amount of chlorine is calculated according to the measured residual chlorine concentration of the effluent, and the control signal is output to the quantitative pump to control the operation of the quantitative pump. Operation of the metering pump is stopped depending on whether the residual chlorine concentration of the water is controlled so that there is no abnormality.

Hereinafter, with reference to the accompanying drawings and embodiments will be described in detail a constant chlorine dosing device capable of remote control according to the present invention. In the drawings, the same reference numerals will be used throughout the specification to omit the parts that are not related to the description in order to clearly illustrate the present invention.

First, a constant chlorine re-insertion device capable of remote control according to an embodiment of the present invention will be described.

1 shows an example of a water supply system to which a chlorine dosing device according to an embodiment of the present invention is applied, and FIG. 2 is a schematic view showing a chlorine resupply device according to an embodiment of the present invention.

As shown in FIG. 1, the water supply system measures the residual chlorine concentration of the water supply drained from the drainage basin 100 and the drainage drainage 100 draining the water supply through the pressure pump P to maintain the set residual chlorine concentration. It may be made of a chlorine input device 200 for introducing chlorine and a consumer 300 receiving water supplied from the chlorine input device 200. At this time, the chlorine injection device 200 is made to properly maintain the concentration of residual chlorine in the water supply so that high-quality water can be consumed in the consumer 300, such as home, factory. The chlorine input tooth 200 inputs chlorine to measure the residual chlorine concentration of the feed water introduced from the reservoir 100 through the water pipe WL and maintain the preset residual chlorine concentration. At this time, the chlorine input device 200 compares the residual chlorine concentration of the discharged water with the set residual chlorine concentration and adjusts the chlorine input flow rate by reflecting the error. Accordingly, the water supply having the optimum residual chlorine concentration from the chlorine dosing device 200 is provided to the consumer 300 to consume high quality water. Hereinafter, the chlorine injection device 200 according to the present invention will be described in more detail.

As shown in Figure 2, the chlorine input device 200 according to an embodiment of the present invention is a flow rate detection unit 210, inlet concentration measurement unit 220, outlet water concentration measurement unit 230, chlorine input unit 240 ), The chlorine storage tank 250, the chlorine injection control unit 260 and the remote control unit 270 can be made.

First, the flow rate detection unit 210 includes a flow meter 212 for transmitting the flow rate data detected from the flow rate sensor 211 installed at equal intervals in the water supply pipe WL to the chlorine injection control unit 260. At this time, the flowmeter 212 converts the flow rate data in the form of a voltage signal, a current signal or a pulse signal and transfers the converted data to the chlorine injection controller 260. Flow rate data transmitted to the chlorine input control unit 260 may be reflected in the process of applying the instantaneous, integrated display of the flow rate and the chlorine re-insertion time. Since the flow rate detection method of the flow rate detection unit 210 is a conventional method, a detailed description thereof will be omitted.

The inlet concentration measuring unit 220 measures the residual chlorine concentration by sampling the water in the water pipe WL through the inlet line 221. The intake line 221 is provided with a plunging valve 222 that can adjust the amount of water intake, the intake concentration measuring unit 220 may determine the amount of sampling of the intake by adjusting the opening degree of the sampling valve 222. The acquisition concentration measuring unit 220 transmits the measured residual chlorine concentration data to the chlorine injection control unit 260 to be described below.

The water extraction concentration measuring unit 230 includes an external sampling line 231 installed outside the water supply pipe WL and a sampling valve 233 which adjusts the sampling amount of the water discharge so as to sample the water supply at a point spaced from the water outlet WL2. do. In practice, the external sampling line 231 is configured to sample the water supply at the point L spaced 20 meters (M) to 30 meters (M) away from the outlet WL2. If the external water collection line 231 takes water at a point before 20 meters (M), the introduced chlorine may not be uniformly mixed with the discharge water, and thus the residual chlorine concentration of the discharge water may be measured unevenly. . On the other hand, when the external sampling line 231 takes in water supply at a point exceeding 30 meters (M), the collection line is too long, which may cause difficulty in installation and management. Therefore, the external sampling line 231 of the water output concentration measuring unit 230 should be appropriately selected within the above-described range. The exiting water concentration measuring unit 230 transmits the measured residual chlorine concentration data to the chlorine input control unit 260 to be described in the same manner as the inlet concentration measuring unit 220.

The chlorine inlet 240 includes a metering pump 241 and an injection tube 242 for introducing chlorine supplied from the metering pump 241 into the water pipe WL. The metering pump 241 is driven by the chlorine injection control unit 260 and injects the chlorine input amount determined by the chlorine injection control unit 260 into the water supply pipe WL. Substantially the metering pump 241 is connected to the chlorine storage tank 250 to be described below is supplied with a certain concentration of liquid chlorine. At this time, the chlorine injection control unit 260 has a capacity to determine the chlorine of a constant flow rate in a unit time, the capacity of this metering pump 241 is recorded in the chlorine input control unit 260. Since the chlorine input unit 240 determines the flow rate of chlorine in accordance with the residual chlorine concentration of the water discharge, in preparation for the case where the flow rate of chlorine to be added in unit time increases and the capacity of the metering pump 241 is exceeded. Pumps with sufficient capacity should be selected.

The chlorine storage tank 250 stores chlorine at a constant concentration. The chlorine storage tank 250 supplies chlorine of a predetermined concentration to the metering pump 241 through the outlet valve 250a. The concentration of chlorine stored in the chlorine storage tank 250 is input to the chlorine input control unit 260 in advance and is reflected in the calculation of the flow rate of chlorine to be introduced through the chlorine input unit 240. In addition, the chlorine storage tank 250 may be provided with a water level sensor 251 for measuring the residual level of chlorine. The chlorine tank 250 frequently transmits chlorine level data to the chlorine input control unit 260 through the water level sensor 251, and the chlorine input control unit 260 controls the overall operation of the chlorine input device 200 according to the chlorine level. do. The chlorine injection control unit 260 displays a warning by using a warning lamp when chlorine is insufficient, and stops driving of the chlorine injection unit 240.

The chlorine input control unit 260 controls the operation of the chlorine input unit 240 according to the determined flow rate and the input time of the chlorine, and the chlorine input control unit 260 is connected to the remote control unit 270 by wire or wirelessly. The remote control unit 270 may receive a remote control signal from the remote control unit 270 and transmit all data related to chlorine input to the remote control unit 270. Accordingly, the chlorine injection device 200 can be conveniently managed from a long distance. Hereinafter, the chlorine injection control unit 260 according to the present invention will be described in detail with reference to other drawings.

3 is a block diagram illustrating the chlorine injection control unit 260 according to an embodiment of the present invention in more detail, and FIG. 4 is a view illustrating an example of a display unit screen of the chlorine injection control unit 260. .

As shown in FIGS. 3 and 4, the chlorine input control unit 260 includes a data input unit 261, a effluent concentration calculation unit 262, a chlorine input amount calculation unit 263, an operation control unit 264, and a key input unit 265. ), A display unit 266, a memory 267, a central control unit 268, and a remote communication unit 269.

First, the data input unit 261 is a flow rate data (FD), the residual chlorine concentration data (SCI) of the water inlet, the residual chlorine concentration data (SCO) and chlorine water level data from each of the flow rate detection unit 210 to the chlorine tank (250) Enter (SLD). The data input unit 261 transfers the input data FD, SCI, SCO, and SLD according to the control signal of the central controller 268 to each unit.

The effluent concentration calculator 262 receives the residual chlorine concentration data SCO of the effluent from the data input unit 261 and calculates the cumulative averaged effluent chlorine concentration in units of a predetermined time T. The water discharge concentration calculator 262 outputs the water discharge chlorine concentration calculated according to the control signal of the central controller 268 to the chlorine input flow rate calculator 263. According to the present invention, the residual chlorine concentration of the effluent is calculated by averaging for a predetermined time (for example, T = 1) and reflected in the determination of the amount of chlorine to be introduced, so that the residual chlorine concentration of the effluent and the set residual chlorine concentration and The error of can be further reduced.

The chlorine input flow rate calculation unit 263 calculates the amount of chlorine to be reinserted by reflecting the output chlorine concentration received from the water output concentration calculation unit 262. According to the present invention, the flow rate of chlorine to be introduced may be selected as shown in [Equation 1].

[Equation 1]

Input Chlorine Amount () = (Pump Capacity () * 10 -3 ) * (Chlorine Concentration (%) / 100) / (Set Chlorine Concentration-Get Chlorine Concentration) * 10 -6 )

Referring to [Equation 1], the flow rate of the chlorine to be re-injected is the capacity of the metering pump 241 and the concentration of chlorine stored in the chlorine tank 250, the set residual chlorine concentration, the residual chlorine concentration of the intake and the residual water of the effluent It can be seen that it is determined according to the chlorine concentration.

The operation control unit 264 controls the operation of the chlorine input unit 240 according to the flow rate data of the chlorine received from the chlorine input flow rate calculation unit 263. That is, the operation control unit 264 outputs an operation control signal DCM that controls the speed of the operation motor of the metering pump 241 according to the control signal of the central control unit 268. Accordingly, the metering pump 241 delivers the chlorine having a flow rate determined according to the speed of the operating motor to the injection tube 242. In addition, when the chlorine level data is lower than the reference, the drive control unit 264 stops the operation of the metering pump 241, thereby adjusting the operation of the pump so as not to cause an excessive force.

The key input unit 265 receives a residual chlorine concentration (FSC) to be set by the administrator, and provides the on / off mode (PM) and the automatic / manual operation mode (RM) of power required for the operation of the chlorine injection control unit 260. Receive input. In addition, through the key input unit 265, the metering pump 241 capacity PC and the chlorine concentration SC of the chlorine storage tank 250 may be input. The input pump capacity and chlorine concentration data are stored in the memory 267 and used for calculating the input amount of chlorine.

The display unit 266 displays information according to the operation of the chlorine input device 200 on the screen. That is, as shown in FIG. 4, the display unit 266 displays the required residual chlorine concentration, the residual chlorine concentration of the inlet and outlet, the accumulated flow rate of the inlet, the chemical remaining amount of the chlorine storage tank 250, the operation state, and the like. To be done. The display unit 266 receives data necessary for displaying a screen from the data input unit 261 and the memory 267 operated according to the control signal of the central control unit 268.

The memory 267 stores an algorithm for calculating the required residual chlorine concentration and the amount of chlorine to be added. The memory 267 reflects and stores the chlorine concentration and the pump capacity input from the key input unit 265 in the algorithm, so that the calculation of the amount of chlorine to be injected is made relatively simple.

The central control unit 268 controls the overall operations of the data input unit 261 to the memory 267 of the chlorine injection control unit 260. That is, the central control unit 268 outputs a control signal to each of the data input units 261 to the memory 267 to help smoothly input chlorine.

The remote communication unit 269 is connected to the remote control unit 270 by wireless or wired so that the chlorine input control unit 260 can be controlled remotely. That is, the remote communication unit 269 transmits the remote control signal RCS received from the remote control unit 270 through the central control unit 268, and transmits data RD related to the input of chlorine to the remote control unit 270. Can be. Since the remote control method of the chlorine injection control unit 260 by the remote control unit 270 may be variously designed according to the design of those skilled in the art by a conventional method, a detailed description thereof will be omitted.

Next, the chlorine input method of the chlorine re-insertion apparatus 200 according to an embodiment of the present invention will be described in more detail.

5, there is shown a flow chart showing a chlorine input method using a chlorine input device 200 according to an embodiment of the present invention.

As shown in Figure 5, the chlorine re-injection method is a chlorine concentration setting step (S110), inlet concentration measurement step (S120), chlorine input step (S130), average outflow concentration calculation step (S140), chlorine input flow rate calculation step (S150), the field variable check step (S160) and the pump drive control step (S170) is made.

First, the chlorine concentration setting step (S110) is a step of receiving a concentration of residual chlorine concentration to be maintained from the key input unit 265. The required residual chlorine concentration may be determined in consideration of the reference value of the legal residual chlorine concentration and the distance to the consumer 300 and the like, for example, selected between 0.7 ppm and 1 ppm. Accordingly, the residual chlorine concentration of the water supply flowing out of the chlorine dosing device 200 and finally supplied from the consumer 300 is maintained at 0.1 ppm to 0.4 ppm. Therefore, it is possible to supply high-quality water with disinfection power to the consumer 300 without having a strong disinfection smell.

The acquisition concentration measurement step (S120) is a step of measuring the residual chlorine concentration of the inflow from the inlet WL1 through the inlet concentration measurement unit 220. The measured residual chlorine concentration is transmitted to the data input unit 261 of the chlorine input control unit 260, and the data input unit 261 stores the residual chlorine concentration of the obtained water by the control signal of the central control unit 268. Output to

The chlorine input step (S130) is a step of introducing chlorine into the water pipe WL through the chlorine input unit 240. The input amount of chlorine to be added is determined using a value obtained by subtracting the residual chlorine concentration of water from the chlorine concentration of the chlorine storage tank 250 and the required residual chlorine concentration at the input time determined through the flow rate data of the flow rate detection unit 210. At this time, the effluent is not in the chlorine input in the chlorine input device 200, so the residual chlorine concentration of the effluent does not participate in the determination of the input amount of chlorine.

The average water output concentration calculating step (S140) is a step of measuring the residual chlorine concentration of the output water from which the residual chlorine concentration is adjusted from the water output concentration measuring unit 230, and accumulating and averaging the measured residual chlorine concentration in a predetermined time unit. The effluent concentration calculation unit 262 of the chlorine input control unit 260 calculates an average of the residual chlorine concentration of the effluent in units of a predetermined time (for example, T = 1), and reflects this in the determination of the flow rate of chlorine to be injected, thereby discharging the effluent. This reduces the error between the residual chlorine concentration and the required residual chlorine concentration.

The chlorine input flow rate calculating step (S150) is a step of calculating a flow rate of chlorine to be input for a predetermined time through the chlorine input flow rate calculation unit 263. The chlorine input flow rate calculation unit 263 determines the flow rate of chlorine to be discharged through the metering pump 241 in a predetermined unit by using the above Equation 1 above. At this time, the discharge unit of the metering pump 241 may be made in a pulse unit or integrated flow unit through the flow rate data input from the flow rate detection unit 210, but is not limited thereto. According to the present invention, by sampling the discharged water at a point spaced from 20 meters (m) to 30 meters (m) from the outlet port WL2, the measured residual chlorine concentration is included in the flow rate of the chlorine to be injected, This can reduce errors and provide better water supply.

The field variable checking step (S160) is a step of checking the field variables such as the remaining amount of chlorine in the chlorine storage tank 250 and whether or not the chlorine concentration of the effluent is abnormal before the metering pump 241 operates. For example, the water level sensor 251 of the chlorine storage tank 250 is connected to the data input unit 261 so as to display the remaining amount of chlorine, but when the chlorine level is 4mA to 20mA to display the chlorine smoothly Since it cannot be made, the operation control unit 264 transmits a signal for stopping the driving of the chlorine input unit 240 to the metering pump 241. In this case, the display unit 266 may display on the screen that the operation of the pump is stopped by the control signal of the central control unit 268. On the other hand, even if the discharged chlorine concentration is higher than the reference concentration than the set the drive control unit 264 can output a drive control signal for stopping the drive of the pump to the chlorine input unit 240.

The pump driving control step S170 is a step in which the driving of the chlorine input unit 240 is controlled by the driving control signal output from the driving control unit 264. In more detail, the operation control unit 264 outputs a signal for controlling the driving of the metering pump 241 to the chlorine input unit 240 in response to the chlorine input flow rate calculation step (S150). do. The rotational speed of the drive motor of the metering pump 241 is changed in accordance with the drive control signal of the drive control unit 264 to finally determine the input amount of chlorine.

In addition, the present invention includes a chlorine input control unit 260 automatically calculates the amount of chlorine in accordance with the residual chlorine concentration of the measured water, and accordingly outputs a drive control signal of the chlorine input unit 240 according to the metering pump The driving of 241 is made to be controlled automatically. In addition, the chlorine-to-be ratio control unit 260 guides the abnormality of the chlorine storage tank 250 to the display unit 226 screen according to whether or not the residual chlorine level of the chlorine storage tank 250 is higher than the residual chlorine concentration, and drives the metering pump 241 to operate. By stopping temporarily, it controls so that there may be no abnormality in residual chlorine concentration of discharged water. Accordingly, the chlorine input device 200 may be more convenient management according to the input of chlorine.

The present invention is not limited to the above specific preferred embodiments, and any person skilled in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention as claimed in the claims. Of course, such changes are within the scope of the claims.
