FIG. 4 is a layout diagram of the white water system water quality sensor 25 in the present embodiment.
[0042]
In the present embodiment, the white water to be monitored for slime state and to which the slime control agent is added based on the monitoring is in the white water pit 84 shown in FIG. 7 described later. In FIG. 4, the white water pit 84 is on the left side of the figure.
[0043]
In monitoring the slime state in FIG. 4, the white water is circulated by the circulation pump 91 as indicated by the large arrow in the figure. That is, the water quality detection tank is introduced from the white water pit 84 to the water quality detection tank 82 in which the white water system water quality sensor 25 is disposed and then returned to the white water pit 84 from the water quality detection tank 82. White water is circulated in the flow path including 82.
[0044]
In connection with the above-mentioned circulation, a filter-like portion 93a is provided in the pipe 93 of the flow passage so that white water can enter and leave the water quality detection tank 82 outside the pipe. That is, the white water in the pipe 93 penetrates from the filter-like portion 93a into the water quality detection tank 82, or the white water in the water quality detection tank 82 penetrates from the filter-like portion 93a into the pipe 93.
[0045]
In FIG. 4, above the water quality detection tank 82, a circulation pump control device 26 for controlling the circulation pumps 91 and 92, a white water-based water quality flow rate / contamination detection device 25e, and a sensor interface device 27 are provided.

Data is input.
[0046]
Further, the white water in the water quality detection tank 82 is circulated as indicated by a small arrow in FIG. 4 in order to detect the white water quality by the white water type water quality differential pressure sensor 25d and the white water type water quality flow rate / contamination detection device 25e.

[0047]
In the circulation by the circulation pump 92, slime generated in the white water adheres to the filter-like slime deposit 50 in the slime deposit structure 86. In addition, due to the adhesion, the flow of white water passing through the slime adhering body structure portion 86 is not disturbed, and the resistance for white water to flow (hereinafter referred to as white water flow resistance) decreases.

It arrange | positions so that the water pressure of the outflow part may be detected. Therefore, the degree of white water flow resistance can be detected from the difference in pressure detected by the two white water system water quality differential pressure sensors 25d.
[0049]
The white water flow resistance when white water flows, the flow velocity (or flow rate), and the pressure are correlated. Therefore, the white water flow resistance and its change can be detected by detecting the flow velocity, detecting the flow rate, or detecting the pressure. Further, the pressure detection may be performed by detecting the upstream pressure or the downstream pressure of the white water flow resistance, or by a differential pressure between these pressure detections. The present invention does not specifically limit the detection and detection of the white water flow resistance and its change.
[0050]
FIG. 5 is an enlarged view of the filter-like slime deposit 50 provided in the slime deposit structure 86.

In unattached (A), the flow of white water flowing as shown by the arrow 57 is disturbed. On the other hand, when slime adheres (B), a slime adhesion layer as indicated by reference numeral 55 is formed, and the flow of white water as shown by the arrow 57 becomes smooth, thereby reducing the white water flow resistance. .
[0054]
FIG. 7 is a block diagram showing the configuration of the drug addition facility in the present embodiment. FIG. 8 is a layout diagram of the chemical addition equipment.
[0055]
First, in FIG. 8, a medicine monitoring control device 30, a memory box device 32, and a mobile phone box device 34 are arranged above the medicine storage tank 80. Reference numeral 39 a denotes an antenna of the mobile phone 39 provided in the mobile phone box device 34. Further, a medicine flow rate / contamination detection device 23, a medicine remaining amount sensor 24, and a medicine addition pump 47 are arranged above the medicine storage tank 80.
[0056]
In FIG. 7, white water for papermaking is stored in the white water pit 84 up to the water level of L1. This white water needs to be sterilized by appropriately adding a slime control agent stored in the medicine storage tank 80, suppress the growth of microorganisms, and suppress the formation of slime. 7 and 8, the slime control agent is stored in the medicine storage tank 80 up to the water level of L2. The water level gradually decreases in accordance with the addition of the drug to the white water pit 84, and rises by replenishing the drug again. The remaining amount of medicine corresponding to the water level is detected by a remaining amount sensor 64 in the stored medicine. A signal corresponding to the remaining amount output from the remaining amount sensor 64 is input to the remaining amount sensor 24. Further, data of the remaining amount detection result of the medicine is inputted from the medicine remaining amount sensor 24 to the data input collecting device 31.
[0057]
In addition, some of the stored medicines deteriorate in quality over time due to ultraviolet rays, temperature conditions, etc., and the bactericidal properties are reduced or lost, making slime control impossible. In the present embodiment, the medicine flow rate / contamination detection device 23 detects the quality of the medicine. In addition, data of the quality detection result of the medicine is input from the medicine flow rate / contamination detection device 23 to the data input collection device 31.
[0058]
The medicine stored in the medicine storage tank 80 is poured into white water in the white water pit 84 by the addition operation of the medicine addition pump 47 and added. In the medicine addition pump 47, the addition flow rate represented by the addition amount per minute can be set by the flow rate setting mechanism 60. In the flow rate setting mechanism 60, the target value of the addition flow rate is written in the register in the addition flow rate setting device 44 of the drug addition control device 42. The addition flow rate setting device 44 operates and adjusts the mechanical mechanism of the flow rate setting mechanism 60 so that the addition flow rate during the addition operation of the drug addition pump 47 becomes the target value.
[0059]
Note that the actual addition flow rate is actually measured by the flow meter 63 in the present embodiment. A signal representing the actually measured addition flow rate is input to the additive drug flow rate sensor 22. In addition, the measured additive flow rate data is input from the additive drug flow rate sensor 22 to the data input collection device 31.
[0060]
In addition, during the stable addition operation after the drug addition pump 47 starts the addition operation, the value of the measured addition flow rate is zero, or the measured value exceeds the preset difference as the normal range. If there is a deviation from the target value, the data input collection device 31 determines that there is some abnormality such as the drug addition pump 47.
[0061]
The medicine addition pump 47 operates only for the on-time set value written in the register in the on-time timer device 45 in the medicine addition control device 42, and thereafter stops operating. Further, after the operation is stopped, when the time of the off-time set value written in the register in the off-time timer device 46 has elapsed, the operation of the on-time timer device 45 is reset, and the drug addition pump 47 is activated again. Thus, the medicine addition pump 47 operates only for the above-mentioned on-time set value, and then repeats the on-off operation cycle of stopping only for the off-time set value. In this embodiment, in the on / off operation cycle, the time from the start of one on to the next start of on is the off time set value written in the register in the off time timer device 46.
[0062]
The drug addition pump 47 is provided with an addition detector using a current sensor. The drug addition operation detection device 21 detects whether or not the drug addition pump 47 is performing an addition operation from the magnitude of the power current flowing through the drug addition pump 47 detected by the addition detector. Information on whether or not the addition operation is being performed is input from the drug addition operation detection device 21 to the data input collection device 31. In this embodiment, the addition operation start of the drug addition pump 47 is detected by the current sensor of the addition detector in this way, and the drug addition pump 47 using such a current sensor is already installed and already in operation. In contrast to the drug addition pump 47 with a proven track record, it is characterized by being relatively easy to install later.
[0063]
2 to 8, as described above, the drug addition operation detection device 21, the added drug flow rate sensor 22, the drug flow rate / contamination detection device 23, the remaining drug amount sensor 24, and the white water-based water quality sensor 25 are respectively applicable. Detection is performed by a detector. These detection results and the detection result of the white water system water quality sensor 25 once input to the sensor interface device 27 are input to the data input collection device 31. The data input collection device 31 writes and accumulates data based on these detection results in the collected data storage device 40 when the addition operation start of the drug addition pump 47 is detected by the drug addition operation detection device 21. The data includes individual detection values and differential values of the detection values indicating whether the detection values tend to increase or decrease.
[0064]
In the present embodiment, since the data is accumulated only when the start of the addition operation is detected in this way, the number of data to be accumulated can be reduced, and the storage capacity of the collected data accumulation device 40 can be effectively utilized. it can.
[0065]
Normally, immediately after the start of the operation of the drug addition pump 47 is detected by the power current of the drug addition pump 47 by the addition detector attached to the drug addition pump 47, the drug addition pump 47 and the like are still stable. In some cases, the operation has not been reached. For example, there may be a case where a predetermined time is required immediately after the start of operation by various detectors such as a power current is detected until the addition operation becomes a stable operation. In such a case, since the detector detects the start of the addition operation, the time point after the lapse of the predetermined time is used as the timing for starting the addition operation, which is the timing for performing data accumulation or the like as described above in the present embodiment. Good.
[0066]
In addition, as a numerical value of the addition amount by the drug addition pump 47 stored in the collected data storage device 40, various numerical values can be appropriately adopted as necessary. For example, the flow rate by the flow meter 63 can be adopted as the addition amount numerical value. Alternatively, as the addition amount numerical value, the total addition amount during the time when the drug addition pump 47 is turned on by the on-time timer device 45, that is, [(flow rate by the flow meter 63) × (on-time of the on-time timer device 45) ] Can also be adopted. Alternatively, as the addition amount numerical value, in the medicine addition pump 47 that operates for the set time of the on-time timer device 45 at the set time interval of the off-time timer device 46 and operates intermittently, The addition flow rate, that is, [{(flow rate by the flow meter 63) × (on time of the on-time timer device 45)} / (off time of the off-time timer device 46)] can also be adopted.
[0067]
The data transfer processing device in the memory box device 32 includes the data stored in the collected data storage device 40 during a polling operation from the data reception processing device 72 of the drug addition control management server device 10 to the data transfer processing device. Then, necessary data is transmitted to the data reception processing device 72. For example, only new data accumulated since the previous polling operation may be transmitted. The transmitted data is stored in the remote data storage device 70 by the data reception processing device 72.
[0068]
The remote control processing device 35 is an addition flow rate setting device 44 that is sent from the papermaking related equipment control arithmetic device 74 during remote operation of the papermaking related equipment control arithmetic device 74 from the papermaking related equipment control arithmetic device 74 of the medicine addition control management server device 10. The addition flow rate data, the on-time data, and the pause time data for writing in the above-described registers of the on-time timer device 45 and the off-time timer device 46 are received. Then, the remote control processing device 35 writes these data in the corresponding register.
[0069]
FIG. 9 is a block diagram illustrating a configuration of the drug addition control management server device 10 according to the present embodiment.
[0070]

[0072]
First, the communication control device 73 performs processing related to data transfer with the drug monitoring control device 30 in the remote monitoring control device 5, the sales management server device 11 and the like in the drug addition control management server device 10.
[0073]
Next, the data reception processing device 72 receives data from the medicine monitoring control device 30. These data are written and stored in the remote data storage device 70 by the data reception processing device 72.
[0074]
In this embodiment, when adding a slime control agent from the storage tank to the papermaking white water system in order to suppress slime production by the growing microorganisms, the start of the operation of the drug addition device that operates at a predetermined pause time interval When the start of operation is detected, the data of the result of detecting the added amount of the medicine, the remaining amount of the storage tank, the medicine quality, and the water quality of the white water system is first input to the data in the medicine monitoring controller 30. The collecting device 31 stores and saves the collected data in the collected data storage device 40 in the memory box device 32. Thereafter, these data are transferred from the collected data storage device 40 by the data transfer processing device by a polling operation from the data reception processing device 72 of the medicine addition control management server device 10 to the data transfer processing device in the memory box device 32. The data is read out, transmitted from the data transfer processing device on the remote monitoring control device 5 side in the remote place to the data reception processing device 72, and stored in the remote data storage device 70.
[0075]
Next, the medicine management message generation device 76 uses the message generation rules stored in the control management database device 71 on the basis of the data stored in the remote data storage device 70, and adds the drug addition. The control management server device 10 predicts the time until there is no medicine of effective quality in the storage tank, and generates a message related to medicine replenishment. For example, the medicine management message generation device 76 decides based on the time required for replenishment of the slime control agent, and when the predicted time is shorter than the preset replenishment grace period, a message such as prompting the medicine replenishment Generate. Alternatively, the medicine management message generation device 76 uses the message generation rules stored in the control management database device 71 as needed based on the data stored in the remote data storage device 70 and other messages.

[0113]
Next, examples of the above-described control rules A1 to A4 in the present embodiment will be described.
[0114]
First, a 1st Example is the following control rules B1-B4 based on the above-mentioned control rules A1-A4, respectively.
[0115]
B1. Based on the temperature detection result of the papermaking white water system by the white water system water temperature sensor 25a, it is predicted that slime may be generated within the temperature range of 30 ° C to 37 ° C, and slime can be generated at other temperature ranges. Predict that there is no gender.
[0116]
B2. Based on the pH detection result of the papermaking white water system by the white water based water quality pH sensor 25b, it is predicted that the slime may be generated if the pH is in the range of 6 to 8, and the slime may be generated in the other pH range. Predicted none.
[0117]
B3. Based on the detection result of dissolved oxygen concentration in papermaking white water system by white water system water dissolved oxygen sensor 25c, if the detected value tends to exponentially decrease, it is predicted that slime may be generated. Otherwise, slime can be generated. Predict that there is no gender.
[0118]
B4. Based on the detection result of the white water flow resistance of the papermaking white water system by the white water type water quality differential pressure sensor 25d, there is a pressure change and this is the white water flow resistance.DeclineIf it is, it is predicted that slime is likely to occur, and otherwise, it is predicted that slime is not likely to occur.
[0119]
In the present embodiment, in these control rules B1 to B4, if there is a possibility of slime generation, a large addition amount is determined or the addition amount is corrected to increase. Alternatively, if there is no possibility of slime generation, a small addition amount is determined, or the addition amount is corrected to decrease.
[0120]
Next, 2nd Example is the following control rules C1-C4 based on the control rules B1-B4 of the above-mentioned 1st Example, respectively.
[0121]
C1. Based on the temperature detection result of the papermaking whitewater system by the whitewater system water temperature sensor 25a, if it is within the temperature range of 30 ° C to 37 ° C, it is predicted that slime may be generated, and “Xtmp = 1” is set. If it is within the range, it is predicted that there is no possibility of slime generation, and “Xtmp = 0” is set.
[0122]
C2. Based on the pH detection result of the papermaking whitewater system by the whitewater system water quality pH sensor 25b, if the pH is in the range of 6 to 8, it is predicted that slime may be generated, and “XpH = 1” is set. Then, it is predicted that there is no possibility of slime generation, and “XpH = 0” is set.
[0123]
C3. Based on the result of detection of dissolved oxygen concentration in the papermaking white water system by the white water system water dissolved oxygen sensor 25c, if the detected value has a tendency of exponential logarithmic decrease, it is predicted that slime may be generated, and “Xdo = 1” is set. Otherwise, it is predicted that there is no possibility of slime generation, and “Xdo = 0” is set.
[0124]
C4. Based on the white water flow resistance detection result of the white paper water quality differential pressure sensor 25d, if there is a pressure change and this is an increase in white water flow resistance, it is predicted that slime may be generated, and “Xsm = 1”. Otherwise, it is predicted that there is no possibility of slime generation, and “Xsm = 0” is set.
[0125]
In this embodiment, the control amount W proportional to the addition amount is obtained by the following equation. Note that Ktmp, KpH, Kdo, and Ksm are control coefficients.
[0126]
W = Xtmp × Ktmp + XpH × KpH + Xdo × Kdo + Xsm × Ksm
[0127]
For example, the temperature is 34 ° C., the pH is 4, the dissolved oxygen concentration tends to decrease exponentially, and there is no pressure change of the white water-based water quality differential pressure sensor 25d.DeclineOtherwise, “Xtmp = 1”, “XpH = 0”, “Xdo = 1”, “Xsm = 0”. Further, it is assumed that the control coefficients are “Ktmp = 20”, “KpH = 40”, “Kdo = 70”, and “Ksm = 125”. Then, based on the above equation, the control amount W of the addition amount is as follows.
[0128]
W = 1 × 20 + 0 × 40 + 1 × 70 + 0 × 125 = 90
[0129]
In these embodiments, the threshold value of each control rule may be another value. Further, the control coefficient in the second embodiment is an example, and may be another value.
[0130]
Also, the threshold values and control coefficients of these examples may be different values in each papermaking white water system of each remote monitoring control device 5 in this embodiment, and such values are individually stored in the control management database device 71. You may make it store. Further, such a value may be automatically learned according to the operation of the papermaking white water system.
[0131]
Furthermore, in the present embodiment, a range that the control amount W can take is set, and according to such a range setting, it is possible to prevent a large amount of addition from being mistaken. Specifically, the control amount W is a flow rate set in the addition flow rate setting device 44, and is set to 0, the minimum flow rate, and 255, the maximum flow rate. Further, the addition amount is the product of such a flow rate and the addition time set in the on-time timer device 45.
