Description

   Capacitive deionization control method and automatic control system thereof   

The present invention relates to a capacitor deionization control technology; more specifically, the present invention relates to a capacitor deionization automatic control method and an automatic control system thereof.

Capacitive deionization (CDI) technology is a new type of water treatment technology, which can be used to remove charged pollutants or ions in water. Compared with traditional deionization procedures with high energy consumption and low recovery rate (such as reverse osmosis deionization), CDI devices have the advantages of low energy consumption and high recovery rate. Furthermore, because the deionization process of the CDI device is reversible and there is no problem of secondary pollutants, the CDI technology is also considered as a clean and energy-saving innovative technology.

In detail, the CDI processing program includes two stages of charge adsorption and discharge desorption. In the charge adsorption stage, when the aqueous solution passes through the CDI device, ions are adsorbed on the electrode due to the force of the electric field and the concentration gradient, so the aqueous solution with a lower ion concentration is purified. In the discharge and desorption stage, the aqueous solution is continuously passed into the CDI device at a fixed flow rate, and the ions are released by the osmium electrode until the ion concentration in the electrode and the ion concentration of the aqueous solution in the flow channel reach equilibrium before the electrode regeneration is completed.

However, the conventional CDI devices all complete the deionization procedure of the aqueous solution by batch operation or manual judgment. Therefore, in addition to the waste of human resources, the current CDI technology is unstable and the accuracy is also a problem worth improving. Furthermore, in the discharge desorption step of the CDI processing program, how to reduce the amount of water in the aqueous solution that is passed into the CDI device to complete the electrode regeneration is also an issue worth improving.

In view of this, how to improve the shortcomings of the conventional CDI technical procedures, reduce the manpower requirements of module operation, improve the operation accuracy, and improve the efficiency of water resource recovery are urgent issues for the industry.

In order to solve the foregoing problem, the present invention discloses a capacitive deionization (CDI) control method for an automatic control system. The automatic control system includes an automatic control server and a CDI device. The automatic control server communicates with the CDI device through a network connection. The automatic control servo includes a processor and a communication module. The CDI device includes a control module and a containing body. The containing body is provided with an aqueous solution pump, an input valve, an output valve, an output solution conductivity sensor, and an electrode plate module.

The CDI control method includes the following steps: the processor sends a charging signal to the CDI device through the communication module. Among them, the charging signal is used to notify the control module to turn on the aqueous pump, and the tritium aqueous solution flows from the input valve into the accommodating body and flows out from the output valve. On the other hand, the charging signal is used to notify the control module to apply a voltage to the electrode plate module to adsorb the ions in the aqueous solution. Then, the processor receives the discharge signal of the control module from the CDI device through the communication module. Among them, the control module judges that the conductivity of the aqueous solution detected by the output solution conductivity sensor rises to equal to the charging threshold and generates a discharge signal.

Subsequently, the processor transmits a static signal to the CDI device through the communication module according to the discharge signal. The stationary signal is used to notify the control module to turn off the aqueous pump, and the tritium aqueous solution is allowed to stand in the housing body. On the other hand, the static signal is used to notify the control module to ground the electrode plate module. After the time interval, the processor sends the extraction signal to the CDI device through the communication module. Among them, the flushing signal is used to notify the control module to turn on the aqueous pump, and the tritium aqueous solution flows from the input valve into the containing body and flows out from the output valve.

To achieve the above object, the present invention further discloses an automatic control system. The automatic control system includes an automatic control server and a CDI device. The automatic control server communicates with the CDI device through a network connection. The CDI device includes a control module and a containing body. The containing body is provided with an aqueous solution pump, an input valve, an output valve, an output solution conductivity sensor, and an electrode plate module.

The automatic control servo includes a processor and a communication module. The processor transmits a charging signal to the CDI device through the communication module. Among them, the charging signal is used to notify the control module to turn on the aqueous pump, and the tritium aqueous solution flows from the input valve into the accommodating body and flows out from the output valve. On the other hand, the charging signal is used to notify the control module to apply a voltage to the electrode plate module to adsorb the ions in the aqueous solution. Then, the processor receives the discharge signal of the control module from the CDI device through the communication module. Among them, the control module judges that the conductivity of the aqueous solution detected by the output solution conductivity sensor rises to equal to the charging threshold and generates a discharge signal.

Subsequently, the processor transmits a static signal to the CDI device through the communication module according to the discharge signal. Among them, the stationary signal is used to notify the control module to turn off the aqueous solution pump, and the tritium aqueous solution is left to stand in the containing body. On the other hand, the static signal is used to notify the control module to ground the electrode plate module. After the time interval, the processor sends the extraction signal to the CDI device through the communication module. Among them, the flushing signal is used to notify the control module to turn on the aqueous pump, and the tritium aqueous solution flows from the input valve into the containing body and flows out from the output valve.

The content of the present invention will be explained below through embodiments. It should be noted that the embodiments of the present invention are not intended to limit the present invention to be implemented in any particular environment, application, or special manner as described in the embodiments. Therefore, the description of the embodiments is only for the purpose of explaining the present invention, and is not intended to limit the present invention, and the scope of the present application is subject to the scope of patent application. In addition, in the following embodiments and drawings, components that are not directly related to the present invention have been omitted and not shown, and the dimensional relationship between the components in the following drawings is only for easy understanding and is not intended to limit Actual proportion.

Please refer to Figures 1A-1B first. FIG. 1A is a schematic diagram of a capacitive deionization (CDI) automatic control system 1 according to a first embodiment of the present invention. The CDI automatic control system 1 includes an automatic control server 11 and a CDI device 13. The automatic control server 11 communicates with the CDI device 13 through a network connection.

FIG. 1B is a block diagram of the automatic control server 11 and the CDI device 13 according to the first embodiment of the present invention. The automatic control server 11 includes a processor 111 and a communication module 113, and the CDI device 13 includes a control module 131 and a receiving body 133. The accommodating body 133 is provided with an aqueous solution pump 133a, an input valve 133b, an output valve 133c, an electrode plate module 133d, an output solution conductivity sensor 133e, and an input solution conductivity sensor 133f. The interaction between the components will be further explained below.

Please refer to Figs. 1C-1E together, which are schematic diagrams of the CDI control operation of the first embodiment of the present invention. First, at the beginning of the CDI control operation procedure, the processor 111 of the automatic control server 11 automatically transmits a charging signal S1 to the CDI device 13 through the communication module 113. Subsequently, as shown in FIG. 1C, the control module 131 turns on the aqueous solution pump 133a according to the charging signal S1. The tritium solution flows from the input valve 133a into the containing body 133, and flows out from the output valve 133c. A voltage is applied to the electrode plate module 133d to adsorb ions in the aqueous solution.

Next, the electrode plate module 133d continues to adsorb the ions of the aqueous solution, so that the conductivity of the aqueous solution first drops to a low conductivity point. Then, since the electrode plate module 133d will gradually reach the state of ion adsorption saturation over time, the electrode plate The number of ions that can be adsorbed by the module 133d will decrease with time, so that the conductivity of the aqueous solution at the output valve 133c gradually increases from the aforementioned low point of conductivity. According to this, when the control module 131 judges that the conductivity of the aqueous solution sensed by the output solution conductivity sensor 133e located near the output valve 133c rises to a charging threshold value, a discharge signal S2 will be generated and automatically The discharge signal S2 is transmitted to the automatic control server 11.

In other words, the detailed situation of the aforementioned "the conductivity of the aqueous solution rises to the charging threshold" is that the conductivity of the aqueous solution first decreases due to the ions in the water being continuously adsorbed to the electrode plate module, and will continue to drop to a specific low point. Subsequently, in a process in which the ion adsorption state of the electrode plate module tends to be saturated with time, the conductivity of the aqueous solution will rise from a specific low point to the charging threshold.

On the other hand, after the processor 111 of the automatic control server 11 receives the discharge signal S2 of the control module 131 from the CDI device 13 through the communication module 113, it automatically transmits a stationary signal S3 to the CDI through the communication module 113.装置 13。 Device 13. Then, as shown in FIG. 1D, the control module 131 of the CDI device 13 closes the aqueous solution pump 133a according to the static signal S3, the tritium aqueous solution stops flowing, and is left in the containing body 133. At the same time, the control module 131 will The electrode plate module 133d is grounded, and the rhenium electrode plate module 133d releases adsorbed ions during the standing process.

Then, after the processor 111 of the automatic control server 11 is left to stand in the aqueous solution in a time interval, it automatically sends a flush signal S4 to the CDI device 13 through the communication module. Then, as shown in FIG. 1E, the control module 131 of the CDI device 13 opens the aqueous solution pump 133a according to the extraction signal S4, and the tritium aqueous solution flows from the input valve 133b into the containing body 133 again, and flows out from the output valve 133c. The aqueous solution with high-concentration ions can be discharged, and the aqueous solution is further used to elute the electrode plate module 133d to help release the remaining adsorbed ions, and complete the aqueous solution deionization cycle after the release is completed.

It should be further emphasized that in the implementation details of the extraction, since the electrode plate module 133d continuously releases ions into the aqueous solution, the ion concentration of the aqueous solution discharged from the output valve 133c will be higher than the ion concentration of the aqueous solution input through the input valve 133b. And the conductivity of the aqueous solution at the output valve 133c will reach a high conductivity first. As the rinsing time increases, during the gradual release of ions from the electrode plate module 133d, the conductivity of the aqueous solution at the output valve 133c will decrease with the decrease of the released ions. According to this, when the control module 131 judges that the conductivity of the aqueous solution detected by the input solution conductivity sensor 133f located near the output valve 133c drops to a discharge threshold value, it will generate a discharge end signal S5, The discharge end signal S5 is transmitted to the automatic control server 11.

In other words, the detailed situation of the aforementioned "conductivity of the aqueous solution falling to the discharge threshold" is that the conductivity of the aqueous solution first rises to a specific high point due to the continuous release of ions by the conductive plate module. Subsequently, in the process that the ion release of the electrode plate module slows down with time, the conductivity of the aqueous solution will drop from a certain high point to the discharge threshold.

On the other hand, when the processor 111 of the automatic control server 11 receives the discharge end signal S5 through the communication module 113, it indicates that the CDI device 13 has completed an aqueous solution deionization cycle. Therefore, the processor 111 of the automatic control server 11 will Through the communication module 113 again, the charging signal S1 is automatically transmitted to the CDI device 13 so as to perform a new deionization cycle of the aqueous solution.

It must be further specified that in some implementations, the charging threshold is a variable set value. Among them, the variable setting value can be adjusted by the user according to the needs of the environment. On the other hand, in some embodiments, the charging threshold is equal to the conductivity of the aqueous solution detected by the input solution conductivity sensor 133f. In this way, when the control module 131 judges the output solution conductivity sensor When the conductivity of the aqueous solution detected by 133e rises to the conductivity of the aqueous solution detected by the input solution conductivity sensor 113f, it means that the aqueous solution flowing into the containing body 133 is not adsorbed by the electrode plate module 133d and then flows out of the containing The main body 133, in other words, the electrode plate module 133d has reached the adsorption saturation state, so the control module 131 generates a discharge signal S2.

Similarly, in some implementations, the discharge threshold value can be a variable setting value adjusted by the user, and can also be equal to the conductivity of the aqueous solution detected by the input solution conductivity sensor 133f. In this way, when When the control module 131 judges the conductivity of the aqueous solution detected by the output solution conductivity sensor 133e and decreases to the conductivity of the aqueous solution of the input solution conductivity sensor 133f, it means that the electrode plate module 133d has no room for inflow. The aqueous solution of the main body 133 releases ions, in other words, the electrode plate module 133d has been discharged, so the control module 131 generates a discharge end signal S5.

It should also be emphasized that for better accuracy of conductivity detection, the aforementioned input solution conductivity sensor and output solution conductivity sensor can be set on the input valve and the output valve respectively, but it is not intended to limit the setting. Its location. Those skilled in the art should be able to adjust the installation position of the solution conductivity sensor according to the technical disclosure of the present invention, and also understand how to adjust the size of the charging threshold and the discharging threshold in different use conditions. The foregoing description is the same. It is not used to limit the implementation of the charging threshold and the discharging threshold.

In addition, those skilled in the art should also understand that the input valve and the output valve may be respectively connected to a plurality of aqueous solution input lines and a plurality of aqueous solution output lines according to circumstances. For example, the CDI device can directly use the aqueous solution to be deionized as the eluent for the discharge process in general use conditions. However, in other implementations, in order to further improve the regeneration efficiency of the electrode plate module, the input valve is visible. Necessary, select a different front-end input line (for example: switch the input line of the aqueous solution to be deionized to a low-ion-concentration aqueous solution line by means of a switch). As a result, the eluent has lower ion Concentration, the efficiency of ion extraction from the electrode plate module will also be improved.

On the other hand, the output valve can also be connected to different back-end output pipelines through the switch to output the deionized aqueous solution and high-concentration ion aqueous solution respectively through different pipelines. In this way, the deionized The aqueous solution and the high ion concentration aqueous solution after the extraction are output separately.

In addition, it should be emphasized that the above-mentioned procedure for standing the aqueous solution in the present invention can greatly increase the concentration of the aqueous solution ions during the flushing in the discharge procedure, so as to reduce the amount of aqueous solution water required for flushing the bank, thereby improving the water recovery efficiency. Among them, with the different time interval of standing, the degree of increase of the ion concentration of the aqueous solution during the extraction process will be different in the discharge process. A person skilled in the art can determine the length of the time period for standing based on actual use conditions and requirements.

For example, the operating conditions are as follows: (1) the electrode plate module used in the CDI device has a size of 20 cm x 20 cm, and the electrode is made of commercial activated carbon; Lithium sodium chloride aqueous solution (brine) is subjected to deionization (desalting) treatment: (3) the voltage applied by the control module to the electrode plate module is 1.2 volts; (4) the aqueous solution pumps the aqueous solution at a flow rate of 10 ml / min Access the accommodation body.

According to this, through the foregoing environment, if the standing time intervals are set to 5 minutes, 10 minutes, 20 minutes, and 30 minutes, respectively, so that the ions in the hole of the electrode plate are transmitted to the aqueous solution containing the main body, the discharge procedure The change of the conductivity data is shown in Figures 1F ~ 1I. It can be understood from the illustration that the longer the time period for standing, the higher the highest concentration of the aqueous solution initially discharged in the subsequent discharge process.

Obviously, the longer the standing time interval, the more the amount of ions diffused from the hole of the electrode plate module to the accommodating body, so that the charging efficiency during discharge can be greatly improved. In addition, from the data changes in Figures 1F ~ 1I, it can be understood together that when the standing time interval is longer, the time during which the discharge flushing makes the electrode plate module completely release ions (that is, the time when the conductivity drops to normal state) also changes Get shorter. In other words, it means that the regeneration speed of the electrode plate module can also be greatly improved, and the electrode regeneration process can be completed with less aqueous water.

In addition, from the data shown in Figure 1J, it can be seen that the water recovery rate increases significantly with the increase of the standing time. Among them, the water recovery rate of 5 minutes was 49.3%, the water recovery rate of 10 minutes was 66.3%, the water recovery rate of 20 minutes was 83.2%, and the water recovery rate was 30 minutes It was 83.4%. In this way, according to the actual data, it can be seen that the standing process has indeed greatly improved the overall processing efficiency of the CDI device.

The detailed steps of the second embodiment are as follows.

First, step 201 is executed, the processor of the automatic control server sends a charging signal to the CDI device through the communication module. Step 202 is executed. The control module of the CDI device turns on the water pump according to the charging signal. The tritium water solution flows from the input valve into the accommodating body and flows out from the output valve. Adsorb ions in aqueous solution.

Then, step 203 is executed. After the control module of the CDI device judges that the conductivity of the aqueous solution detected by the conductivity sensor of the output solution rises to a charging threshold, it generates a discharge signal and transmits the discharge signal to the automatic control servo. Device. Step 204 is executed, the processor of the automatic control server receives the discharge signal from the CDI device through the communication module. Step 205 is executed, and the processor of the automatic control server transmits a static signal to the CDI device through the communication module according to the discharge signal.

Similarly, the detailed status of the aforementioned "conductivity of the aqueous solution rises to the charging threshold" is that the conductivity of the aqueous solution first decreases due to the ions in the water being continuously adsorbed to the electrode plate module, and will continue to drop to a specific low point. Subsequently, in a process in which the ion adsorption state of the electrode plate module tends to be saturated with time, the conductivity of the aqueous solution will rise from a specific low point to the charging threshold.

Subsequently, step 206 is executed, the control module of the CDI device turns off the aqueous solution pump according to the static signal, the tritium aqueous solution is left standing in the containing body, and at the same time, the control module grounds the electrode plate module. Step 207 is executed. After a time interval, the processor of the automatic control server sends a flush signal to the CDI device through the communication module.

Next, step 208 is executed, the control module of the CDI device turns on the aqueous solution pump according to the extraction signal, and the tritium aqueous solution flows from the input valve into the accommodating body and flows out from the output valve. In this way, the aqueous solution with high concentration of ions can be discharged, and at the same time, the electrode plate module is further flushed with the aqueous solution to help release the remaining adsorbed ions, and after the release is completed, the aqueous solution deionization cycle is completed.

It should be particularly emphasized that, similarly, if further implementation is considered, please also refer to Figure 2B. In detail, in the implementation details of the extraction, step 209 can be further performed. After the control module of the CDI device judges that the conductivity of the aqueous solution of the output valve drops to a discharge threshold value, it will generate a discharge end signal, and Discharge end signal is sent to the automatic control server.

Similarly, the detailed situation of the aforementioned “conductivity of the aqueous solution falling to the discharge threshold” is that the conductivity of the aqueous solution first rises to a specific high point due to the continuous release of ions by the conductive plate module. Subsequently, in the process that the ion release of the electrode plate module slows down with time, the conductivity of the aqueous solution will drop from a certain high point to the discharge threshold.

According to this, step 210 is executed. After the processor of the automatic control server receives the end-of-discharge signal through the communication module, it indicates that the CDI device has completed an aqueous solution deionization cycle. Therefore, the processor of the automatic control server automatically automatically communicates again through communication. The module sends a charging signal to the CDI device, and then returns to step 201 to perform a new aqueous solution deionization cycle.

Similarly, regarding the CDI control method of the second embodiment, in some implementation aspects, the charging threshold value is a variable set value. Among them, the variable setting value can be adjusted by the user according to the needs of the environment. On the other hand, in some embodiments, the charging threshold is equal to the conductivity of the aqueous solution detected by the input solution conductivity sensor. In this way, when the control module of the CDI device judges the output solution conductivity sensing When the conductivity of the aqueous solution detected by the sensor rises to the conductivity of the aqueous solution detected by the input solution conductivity sensor, it means that the aqueous solution flowing into the accommodating body is flowed out of the accommodating body without being adsorbed by the electrode plate module, in other words, That is, the electrode plate module has reached the adsorption saturation state, so the control module generates a discharge signal.

On the other hand, in some implementations, the discharge threshold value can also be a variable set value adjusted by the user, and can also be equal to the conductivity of the aqueous solution detected by the input solution conductivity sensor. When the control module judges that the conductivity of the aqueous solution detected by the conductivity sensor of the output solution drops to the conductivity of the aqueous solution detected by the conductivity sensor of the input solution, it means that the electrode plate module has not been directed to flow into the accommodating body. The aqueous solution releases ions, in other words, the electrode plate module has been discharged, so the control module generates an end-of-discharge signal.

To sum up, the CDI control method and the automatic control system provided by the present invention can complete the overall process of the CDI device through automated detection and signal transmission. In this way, human resources can be saved and the accuracy of the results can be improved. Furthermore, the CDI control method and the automatic control system provided by the present invention have an innovative discharge program, and it can be known from the experimental data that the improved program can effectively accelerate the CDI extraction efficiency and greatly improve the water recovery rate.

However, the above-mentioned embodiments are merely for exemplifying the implementation aspects of the present invention and explaining the technical features of the present invention, and are not intended to limit the protection scope of the present invention.
