Description

Technical Field

[0001] This invention relates to the field of water treatment technology, and more specifically, to an intelligent online monitoring device for water treatment environment and its remote control system. Background Technology

[0002] In the process of circulating water treatment, in order to solve the corrosion and scaling problems caused by water concentration during the operation of the circulating water system, it is necessary to add scale and corrosion inhibitors. There are two existing methods for adding scale and corrosion inhibitors: shock dosing and continuous dosing. Shock dosing has been eliminated because of the large fluctuation of the agent concentration in the system, which makes it unable to cope with the operation of the system at low concentration ratios. Continuous dosing can ensure uniform agent concentration in the system and has the advantages of accurate metering and convenient adjustment. However, continuous dosing is only a dosing method, that is, the dosing pump is set to a fixed opening and a fixed amount of agent is added every day. It cannot determine whether the dosage of scale and corrosion inhibitors is appropriate. Therefore, when the system water quality changes, the dosage cannot be adjusted in time. The dosage can only be adjusted by detecting water quality changes on a daily or longer water quality monitoring cycle. This easily leads to problems such as insufficient agent concentration when the circulating water treatment system has a large amount of replenishment and drainage, and excessive agent concentration when the concentration ratio increases during continuous non-discharge of the system, resulting in agent waste.

[0003] Based on this, an intelligent online monitoring device for water treatment environment and its remote control system are proposed. Summary of the Invention

A limiting plate is fixedly sleeved on the outer surface of the other end of the discharge pipe, and a threaded joint is rotatably sleeved on the outer surface of the limiting plate. The threaded joint is screwed into the dosing port.

[0008] As a further improvement of the present invention, the inlet and outlet ends of the second metering pump are both fixedly connected with sampling tubes. The other end of the sampling tube at the outlet end of the second metering pump is connected to the sample container. The other end of the sampling tube at the inlet end of the second metering pump is connected to the sample container. A threaded opening is provided in the middle of the lower surface of the sample container. The sample container is screwed into the upper part of the outer surface of the return port through the threaded opening.

[0009] As a further improvement of the present invention, a piston is provided inside the sampling tank, and an inverted "L"-shaped connecting frame extending outward through the sampling tank is provided in the middle of the outer surface of the piston away from the filter tank. An electric telescopic rod is provided below the sampling tank, and the output end of the electric telescopic rod is fixedly connected to the vertical end of the connecting frame. The electric telescopic rod is fixedly connected to the assembly frame.

[0010] As a further improvement of the present invention, the end of the filter tank near the monitoring tube is spirally sleeved onto the outer surface of the sampling port, and an interception net is fixedly installed on the inner surface of the filter tank near the sampling tank. A support shaft is provided in the middle of the outer surface of the interception net near the sampling port. A concave limiting groove is opened in the middle of the outer surface of the support shaft. The interception net leaf is rotatably sleeved onto the support shaft through the outer surface of the limiting groove.

[0011] As a further improvement of the present invention, the main controller includes a database, a control module, an analysis module, a hosting module, and a signal transmission unit; The database is used to store reference values ​​for the dosage of scale inhibitors and corrosion inhibitors required for different water qualities during the circulating water treatment process. The control module is electrically connected to the on / off valve, the first metering pump, the second metering pump, and the electric telescopic rod, and is used to control the opening and closing of the on / off valve, the first metering pump, the second metering pump, and the electric telescopic rod, as well as their operating power.

The analysis module analyzes the feedback signals received from the flow meter component and the online water quality analyzer to obtain the reference value for the dosage of scale and corrosion inhibitor.

[0012] The beneficial effects of this invention are: In the process of circulating water treatment, this invention can perform quantitative online sampling and detection of circulating water to obtain the total phosphorus and zinc concentrations in the quantitative sample of circulating water due to the addition of scale and corrosion inhibitors. Based on the total phosphorus and zinc concentrations in the quantitative sample of circulating water, the amount of scale and corrosion inhibitor to be added can be determined and controlled, which is conducive to rational control of the dosage, saving the consumption of scale and corrosion inhibitors while ensuring the treatment effect of circulating water. When performing quantitative sampling of circulating water, this invention can filter and intercept suspended solids in the circulating water, thereby reducing the turbidity of the circulating water and improving detection efficiency and accuracy. At the same time, the filtered and intercepted suspended solids can be reversed and discharged, thereby avoiding the phenomenon of suspended solids clogging the sampling mechanism. This helps to ensure stable circulating water detection and sampling while reducing cleaning and maintenance costs. Attached Figure Description

It should be understood that such data can be interchanged where appropriate for the embodiments of the invention described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0018] To make the objectives and advantages of the present invention clearer, the present invention will be further described below with reference to embodiments; it should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0019] Please see Figures 1-9 As shown, a water treatment environment intelligent online monitoring device and its remote control system include a monitoring tube 1. A dosing port 101 is fixedly connected to the front end of the upper surface of the monitoring tube 1, and a return port 102 is fixedly connected to the rear end of the upper surface of the monitoring tube 1. An on / off valve 103 is provided inside the return port 102. A sampling port 104 is fixedly connected to the rear end of one side of the outer surface of the monitoring tube 1. A baffle 105 is fixedly installed on the rear end of the inner top surface of the monitoring tube 1, vertically aligned with the return port 102. A first baffle impeller 106 and a second baffle impeller 107 are rotatably installed at both ends of the middle part of the inner surface of the monitoring tube 1, respectively. The blades of the first baffle impeller 106 and the second baffle impeller 107 are arranged in opposite directions. A flow meter assembly 108 is fixedly installed at the front end of the monitoring tube 1. It should be noted that by using monitoring pipe 1 to replace a section of the circulating water pipe, monitoring pipe 1 is used to monitor and sample the circulating water during the indirect circulation of the circulating water. Both ends of monitoring pipe 1 can be sealed to the circulating water pipe through connecting flanges to prevent leakage during the circulation of the circulating water. Secondly, the flow meter assembly 108 set at the front end of monitoring pipe 1 can indirectly connect monitoring pipe 1 and circulating water pipe in series. Circulating water will enter monitoring pipe 1 through flow meter assembly 108, thereby using flow meter assembly 108 to monitor the flow rate of the circulating water, so as to add scale inhibitors and corrosion inhibitors according to the flow rate of the circulating water. The scale and corrosion inhibitor can be added to the monitoring pipe 1 through the dosing port 101, thereby blending with the circulating water flowing through the monitoring pipe 1 and synergistically achieving the key role of controlling scaling, corrosion and microbial contamination. When the circulating water with added scale and corrosion inhibitor flows through the first turbulence impeller 106 and the second turbulence impeller 107 in the monitoring pipe 1, the flow impact of the circulating water will drive the first turbulence impeller 106 and the second turbulence impeller 107 to rotate. The rotation of the first turbulence impeller 106 and the second turbulence impeller 107 will disturb the circulating water and improve its compatibility with the scale and corrosion inhibitor. Since the blades of the first turbulence impeller 106 and the second turbulence impeller 107 are set in opposite directions, their disturbance directions on the circulating water are opposite, further improving the disturbance and fusion effect. Sampling port 104 is provided to facilitate the sampling of circulating water from monitoring tube 1. The circulating water sample after sampling and testing can be discharged back into monitoring tube 1 through return port 102. The flow of circulating water back into monitoring tube 1 can be controlled by controlling the opening and closing state of the opening and closing valve 103 set at return port 102. The opening and closing valve 103 is a solenoid valve. By setting a baffle 105 at the position corresponding to return port 102 in monitoring tube 1, the circulating water in monitoring tube 1 can be diverted when it flows through return port 102, thereby reducing the flow pressure at return port 102, so that the circulating water sample can flow back into monitoring tube 1 through return port 102.

[0020] An assembly frame 2 is fixedly installed on the outer surface of the monitoring tube 1. A main controller 201 is fixedly installed in the middle of the outer surface of the assembly frame 2. A first metering pump 3 is fixedly installed at the lower front end of the outer surface of the assembly frame 2 away from the monitoring tube 1. A suction pipe 304 is fixedly connected to the inlet end of the first metering pump 3. A discharge pipe 301 is fixedly connected to the outlet end of the first metering pump 3. A limit plate 302 is fixedly installed on the outer surface of the other end of the discharge pipe 301. A threaded joint 303 is rotatably installed on the outer surface of the limit plate 302. The threaded joint 303 is screwed into the dosing port 101. It should be noted that the assembly frame 2 is used to support and install the monitoring tube 1, while also assisting in the installation and fixation of other components. The main controller 201 is used for the operation control of the entire monitoring device. The first metering pump 3 is used as a dosing pump to control the quantitative addition of scale and corrosion inhibitor. The suction pipe 304 can be connected to the scale and corrosion inhibitor storage container. The first metering pump 3 can draw up the scale and corrosion inhibitor and input it into the monitoring tube 1 through the discharge pipe 301 and the dosing port 101. The fixed connection between the discharge pipe 301 and the dosing port 101 is completed by screwing the threaded connector 303 into the dosing port 101. Since the threaded connector 303 is sleeved on the outer surface of the limiting plate 302, it is ensured that the normal rotation of the threaded connector 303 for installation and connection is not affected.

[0021] A second metering pump 4 is fixedly installed at the middle of the rear end of the outer surface of the assembly frame 2 away from the monitoring tube 1. A sample tank 5 is set above the rear end of the upper surface of the monitoring tube 1. The inlet and outlet ends of the second metering pump 4 are both fixedly connected with sampling tubes. The other end of the sampling tube at the outlet end of the second metering pump 4 is connected to the sample tank 5. The other end of the sampling tube at the inlet end of the second metering pump 4 is connected to the sampling tank 7. A threaded opening is opened in the middle of the lower surface of the sample tank 5. The sample tank 5 is screwed into the upper part of the outer surface of the return port 102 through the threaded opening. A water quality online analyzer 6 is fixedly installed at the upper rear end of the outer surface of the assembly frame 2 away from the monitoring tube 1. A detection probe 601 is electrically connected and installed on the upper surface of the water quality online analyzer 6. The detection end of the detection probe 601 is inserted into the sample tank 5. It should be noted that the second metering pump 4 is used to control the sampling amount of circulating water test samples, so as to determine whether the addition amount of scale inhibitor and corrosion inhibitor is reasonable by detecting the concentration of total phosphorus and zinc in a specific amount of circulating water. The second metering pump 4 will transport the circulating water sample drawn from the sampling tank 7 to the sample tank 5 for testing. The sample tank 5 is screwed and installed on the return port 102. In this case, the circulating water sample in the sample tank 5 can be discharged back into the monitoring tube 1 by controlling the opening and closing of the opening and closing valve 103, so as to empty the sample tank 5 for subsequent periodic testing of circulating water. The detection probe 601 is inserted into the sample tank 5 using the online water quality analyzer 6 to detect the concentration of total phosphorus and zinc in the circulating water sample online and obtain the detection values.

[0022] A sampling container 7 is fixedly installed at the lower rear end of the outer surface of the assembly frame 2 away from the monitoring tube 1. A filter container 9 is screwed into the end of the sampling container 7 near the monitoring tube 1. A piston 701 is installed inside the sampling container 7. A connecting frame 702 in an inverted "L" shape extends outward through the sampling container 7 is installed in the middle of the outer surface of the piston 701 away from the filter container 9. An electric telescopic rod 8 is installed below the sampling container 7. The output end of the electric telescopic rod 8 is fixedly connected to the vertical end of the connecting frame 702. The electric telescopic rod 8 is fixedly connected to the assembly frame 2. It should be noted that the sampling tank 7 is used to guide the circulating water in the monitoring tube 1 to flow out for sampling and testing. The piston 701 is controlled to move laterally in the sampling tank 7 by the extension and retraction of the electric telescopic rod 8 and the auxiliary connecting frame 702. When the electric telescopic rod 8 is in the extended state, it can drag the piston 701 away from the filter tank 9. At this time, the sampling tank 7 will be in a negative pressure suction state, thereby drawing the circulating water in the monitoring tube 1 out through the sampling port 104. Under this condition, the sampling tank 7 will be connected to the monitoring tube 1, and the second metering pump 4 can extract and sample the circulating water in the sampling tank 7. Secondly, when the circulating water flows through the filter tank 9 into the sampling tank 7, the filter tank 9 will filter and intercept the suspended solids in the circulating water, thereby reducing the turbidity of the circulating water sample and improving the detection efficiency and accuracy. The suspended solids intercepted in the filter tank 9 can be controlled by the retraction of the electric telescopic rod 8 to move the piston 701 closer to the filter tank 9. At this time, the piston 701 will push the circulating water in the sampling tank 7 towards the monitoring tube 1. During the reverse flow of the circulating water, the suspended solids intercepted in the filter tank 9 can be pushed and cleared, and the suspended solids are pushed into the monitoring tube 1 along with the circulating water to ensure the unobstructed state of the filter tank 9 and reduce maintenance and cleaning costs.

[0023] The filter tank 9 is spirally sleeved to the outer surface of the sampling port 104 at one end near the monitoring tube 1. An interception net 901 is fixedly installed on the inner surface of the filter tank 9 at one end near the sampling tank 7. A support shaft is provided in the middle of the outer surface of the interception net 901 at one end near the sampling port 104. A concave limiting groove is opened in the middle of the outer surface of the support shaft. The interception net leaf 902 is rotatably sleeved on the support shaft through the outer surface of the limiting groove. It should be noted that the circulating water sample is filtered for suspended solids through the filter tank 9. When the circulating water in the sampling tank 7 draws the monitoring tube 1 through the filter tank 9, the circulating water will flow and impact the intercepting net leaf 902, causing it to rotate. At this time, the rotating intercepting net leaf 902 can intercept and capture the suspended solids in the circulating water. At the same time, the intercepting net 901 will further filter and intercept the remaining suspended solids, thereby reducing the suspended solids content in the circulating water sample and improving the detection efficiency and accuracy of the sample.

[0024] The main controller 201 includes a database, a control module, an analysis module, a management module, and a signal transmission unit; The database is used to store reference values ​​for the dosage of scale inhibitors and corrosion inhibitors required for different water qualities during the circulating water treatment process. Specifically, the database stores a pre-defined water quality dosage correspondence model, including the baseline dosage of scale and corrosion inhibitors required for different water quality types. The water quality type is based on the concentration ratio of each component in a certain volume of circulating water. Components include hardness, pH, alkalinity, conductivity, and key ion concentrations. Component analysis can be performed on a certain volume of circulating water sample before each batch of circulating water is treated. Based on the water quality component concentration parameters, a water quality type is constructed according to the treatment requirements of the circulating water, and high concentration threshold ranges for each water quality component are set. medium concentration low concentration ...Based on the proportion of the threshold range corresponding to the concentration parameters of each water component, the required dosage of scale inhibitor and corrosion inhibitor for each water component is determined to be high, medium, or low. The required dosage of scale inhibitor and corrosion inhibitor varies depending on the water type and the treatment requirements. A water quality dosage correspondence model is constructed based on the scale inhibitor and corrosion inhibitor dosages corresponding to a certain volume of water type. The control module is electrically connected to the on / off valve 103, the first metering pump 3, the second metering pump 4 and the electric telescopic rod 8, and is used to control the opening and closing of the on / off valve 103, the first metering pump 3, the second metering pump 4 and the electric telescopic rod 8 as well as their operating power. The managed module is used to adjust the dosage of scale inhibitor and corrosion inhibitor by itself when the remote control fails to respond for a certain period of time during the remote signal control adjustment of the dosage. Based on the reference value of the dosage of scale inhibitor and corrosion inhibitor obtained by the analysis module, it compares the reference value of the dosage of scale inhibitor and corrosion inhibitor corresponding to the circulating water quality in the database. It also controls the operation of the opening and closing valve 103, the first metering pump 3, the second metering pump 4 and the electric telescopic rod 8 through the control module according to the predetermined preset process. Specifically, the managed module will set a no-response timeout threshold. For example, if no remote control command is received within three minutes, it can be determined that the remote control has timed out and no response has been received. The module will then immediately switch from the remote control state to the autonomous operation mode. The predetermined process control steps for the on / off valve 103, the first metering pump 3, the second metering pump 4, and the electric telescopic rod 8 are as follows: S1. Based on the reference value of scale inhibitor and corrosion inhibitor dosage obtained by the analysis module, the scale inhibitor and corrosion inhibitor dosage is automatically adjusted by comparing the corresponding reference value of scale inhibitor and corrosion inhibitor dosage in the database. The first metering pump 3 is controlled to extract the scale inhibitor and corrosion inhibitor and continuously add it to the monitoring pipe 1 to mix with the circulating water. S2. Control the opening and closing valve 103 to open and discharge the circulating water sample in the sample tank 5 into the monitoring tube 1, and control the electric telescopic rod 8 to be in the retracted state to drive the piston 701 to push the circulating water in the sample tank 7 back into the monitoring tube 1. S3. Control the opening and closing valve 103 to close, the electric telescopic rod 8 is in the extended state, driving the piston 701 to reintroduce the circulating water in the monitoring tube 1 into the sampling tank 7, and start the second metering pump 4 to extract a certain volume of circulating water and send it into the sample tank 5 for water quality component detection again. The signal transmission unit includes signal transmission module one and signal transmission module two; The signal transmission module 1 is used to transmit control signals from the control module to the on / off valve 103, the first metering pump 3, the second metering pump 4 and the electric telescopic rod 8, and to receive operating status feedback signals from the on / off valve 103, the first metering pump 3, the second metering pump 4 and the electric telescopic rod 8. At the same time, it receives feedback signals from the flow meter assembly 108 and the online water quality analyzer 6 and transmits them to the analysis module. The signal transmission module 2 is used to transmit and receive remote control signals for the on / off valve 103, the first metering pump 3, the second metering pump 4 and the electric telescopic rod 8, and to remotely transmit feedback signals from the flow meter assembly 108, the online water quality analyzer 6 and the analysis module to the mobile terminal of the management personnel. The analysis module analyzes the feedback signals received from the flow meter component 108 and the online water quality analyzer 6 to obtain the reference value for the dosage of scale inhibitor and corrosion inhibitor. Specifically, the online water quality analyzer 6, in conjunction with the detection probe 601, analyzes the water composition of a certain volume of circulating water sample and further obtains the total phosphorus and zinc concentrations of the circulating water after adding scale inhibitors and corrosion inhibitors. The total phosphorus and zinc concentrations that a certain volume of circulating water should contain after adding scale inhibitors and corrosion inhibitors are set as thresholds and threshold ranges are constructed. The total phosphorus and zinc concentrations of the same volume of circulating water sample after adding scale inhibitors and corrosion inhibitors are compared with the threshold ranges. If the total phosphorus and zinc concentrations in the circulating water sample are within the threshold range, it indicates that the dosage of scale and corrosion inhibitor added to the current circulating water sample is within a reasonable range. If the total phosphorus and zinc concentrations in the circulating water sample are greater than the threshold range, it indicates that the dosage of scale and corrosion inhibitor added to the current circulating water sample is too high. In this case, the reduction value is set as the amount of scale and corrosion inhibitor added that needs to be reduced to the threshold range. The reference dosage is obtained by subtracting the reduction value from the current amount of scale and corrosion inhibitor added to the circulating water sample. If the total phosphorus and zinc concentrations in the circulating water sample are less than the threshold range, it indicates that the dosage of scale and corrosion inhibitor added to the current circulating water sample is too low. In this case, the increase value is set as the amount of scale and corrosion inhibitor added that needs to be increased to the threshold range. The reference dosage is obtained by adding the increase value to the current amount of scale and corrosion inhibitor added to the circulating water sample.

[0025] In use, the present invention first replaces a section of the circulating water pipe with a monitoring pipe 1. Both ends of the monitoring pipe 1 are sealed to the circulating water pipe through connecting flanges. During the connection process, flow meter components 108 are installed at intervals at the flow point from the circulating water pipe to the monitoring pipe 1. The circulating water will then enter the monitoring pipe 1 through the flow meter components 108, thereby monitoring the flow rate of the circulating water. At this time, the operator can take a volume of circulating water with the same instantaneous flow rate along the pipe in advance to test its composition content, and determine the water quality type of the circulating water to be treated based on the composition content. The water quality type is then sent to the main controller 201 to obtain the corresponding dosage of scale inhibitor and corrosion inhibitor. At this point, the circulating water treatment process can begin. The circulating water flows through the pipeline, passes through the flow meter assembly 108, and enters the monitoring pipe 1. The flow meter assembly 108 accumulates the circulating water flow rate. Then, the first metering pump 3 is started, using the suction pipe 304 to extract the scale and corrosion inhibitor, which is then fed into the monitoring pipe 1 through the discharge pipe 301 and the dosing port 101. During the delivery of the scale and corrosion inhibitor by the first metering pump 3, the total delivery volume needs to be monitored to ensure it matches the circulating water flow rate accumulated by the flow meter assembly 108. Once the scale and corrosion inhibitor enters the monitoring pipe 1, it can mix with the circulating water and continue to flow along the monitoring pipe 1. At this time, when the circulating water with added scale and corrosion inhibitor flows through the first turbulence impeller 106 and the second turbulence impeller 107 in the monitoring pipe 1, the flow impact of the circulating water will drive the first turbulence impeller 106 and the second turbulence impeller 107 to rotate. Thus, the rotation of the first turbulence impeller 106 and the second turbulence impeller 107 will disturb the circulating water and improve its compatibility with the scale and corrosion inhibitor. When the circulating water flows to the sampling port 104, the electric telescopic rod 8 is activated and extended, thus dragging the piston 701 away from the filter tank 9. At this time, the sampling tank 7 will be in a negative pressure suction state, thereby drawing the circulating water in the monitoring tube 1 out through the sampling port 104 and flowing through the filter tank 9 into the sampling tank 7. When the sampling tank 7 draws the circulating water in the monitoring tube 1 through the filter tank 9, the circulating water will flow and impact the interception net leaf 902, causing it to rotate. At this time, the rotating interception net leaf 902 can intercept and capture suspended solids in the circulating water. At the same time, the interception net 901 will further filter and intercept the remaining suspended solids, reducing the suspended solids content in the circulating water entering the sampling tank 7. Next, the second metering pump 4 extracts a circulating water sample of the same volume as the instantaneous flow rate from the sampling tank 7 and transports it to the sample tank 5 for testing. The online water quality analyzer 6, along with the detection probe 601, is inserted into the sample tank 5 to detect the concentration of total phosphorus and zinc in the circulating water after the addition of scale and corrosion inhibitors. The data is then transmitted to the main controller 201. At this point, the main controller 201 can analyze the concentration of total phosphorus and zinc to determine whether the dosage of scale and corrosion inhibitors added corresponds to the current concentration of total phosphorus and zinc. If it is reasonable, the scale and corrosion inhibitors will continue to be added according to the current dosage. If the dosage is too high or too low, the first metering pump 3 will be controlled to increase or decrease the amount of scale and corrosion inhibitor delivered accordingly. After the circulating water sample is tested, the on / off valve 103 at the return port 102 is opened. At this time, the circulating water sample in the sample tank 5 will flow back into the monitoring tube 1 through the return port 102. After the circulating water in the sample tank 5 is discharged, the on / off valve 103 can be closed. At this time, the electric telescopic rod 8 is controlled to be in the retracted state, and the piston 701 is controlled to approach the filter tank 9. At this time, the piston 701 will push the circulating water in the sampling tank 7 towards the monitoring tube 1. During the reverse flow of the circulating water, the suspended solids intercepted in the filter tank 9 can be pushed and cleaned. The suspended solids are pushed into the monitoring tube 1 along with the circulating water to ensure the unobstructed state of the filter tank 9 and reduce maintenance and cleaning costs. Finally, repeat the above process of circulating water sampling to perform multiple sampling tests on the circulating water flowing in monitoring pipe 1, and adjust the dosage of scale inhibitor and corrosion inhibitor in real time according to the test results.
