[0048] The information sensing module includes a first detection element, a second detection element, and a third detection element;

[0049] The function execution module includes a solution adjustment device, a desorption adjustment device, and an electrolysis adjustment device;

[0050] The host computer 2 includes a switch connected to the CPU module of the PLC controller 1 and a touch screen connected to the switch. The host computer 2 also includes an IOT module connected to the CPU module of the PLC controller 1 and a cloud platform connected to the IOT module.

[0054] The desorption adjustment device includes a heating device 42 disposed in the heater 52 , which is used to adjust the temperature of the solution in the heater 52 .

[0055] The electrolysis adjustment device includes an electric valve 431 arranged on an external discharge pipeline connected to the outlet of the electrolytic cell 54 and a rectifier 432 connected to one end of the electrolytic cell 54; the electric valve 431 is used to regulate the pressure in the electrolytic cell 54, and the rectifier 432 is used to regulate the state of the current in the electrolytic cell 54.

[0056] The PLC controller 1 uses a PID fuzzy intelligent control algorithm to control the heating device 42 in the heater 52 .

[0057] The following is an explanation of the workflow of an intelligent desorption electrolysis control system provided by the present invention:

[0058] like Figure 1 As shown, the information sensing module is used to sense various parameters in the desorption electrolysis process.

[0059] The function execution module is used to execute control instructions.

[0060] The PLC controller 1 serves as the control core, receives data collected by the information sensing module, generates control instructions through the logic control algorithm, and guides the actions of the function execution module.

[0061] The touch screen serves as a human-computer interaction interface, which can set process parameters and monitor and record the operating status of equipment and instruments. It also has the functions of dynamic screen display, real-time data and historical data query and export, process curve display, early warning and alarm functions; the PLC controller 1 and the touch screen are electrically connected through a switch to realize data transmission and information interaction in the local area network.

[0062] The PLC controller 1 is electrically connected to the IOT module, wherein the PLC controller 1 exchanges information with the cloud platform through the IOT module to realize remote monitoring and management of the desorption electrolysis control system; the IOT module serves as a bridge connecting the terminal device and the cloud platform, and realizes data communication and information interaction between the device and the cloud through the 4G Internet of Things gateway or the WIFI Internet of Things gateway, so that the system has the function of remote monitoring and control.

[0063] This intelligent desorption electrolysis control system has both manual and automatic control modes. In automatic mode, the desorption electrolysis process can be automatically controlled by operating the start and stop options on the touch screen on site; or remote control can be performed on the cloud platform, both of which have one-button start and stop functions. In manual mode, the desorption electrolysis process can be controlled by the on-site operator by operating the valve.

[0064] The following describes the working process using the automatic mode as an example: in the preparation stage, set the process parameters and alarm parameters on the touch screen interface, including the temperature setting value of the heating system used in the heater 52, the temperature at which desorption starts and the time for desorption in the desorption device, the output voltage and output current of the rectifier 432, and the numerical alarm limits detected by the level meter, flow meter 312, desorption pressure transmitter, and temperature detection software; after the preparation stage is completed, click the one-touch start button on the touch screen and the system will run automatically.

[0065] The PLC controller 1 uses a PID fuzzy intelligent control algorithm to control the heating device 42 in the heater 52 so that the temperature in the heater 52 reaches a set temperature value.

[0066] The PLC controller 1 turns on the desorption pump 41, allowing the solution in the solution tank 51 to flow into the heater 52, and when the PLC controller 1 receives the change signal of the solution tank liquid level meter 311 (the solution is reduced to the target amount), the PLC controller 1 controls the heating device 42 in the heating device 42 to turn on and heat the solution; after the PLC controller 1 receives the signal of the desorption temperature detection element 1 3221 (the solution is heated to the target temperature), the PLC controller 1 opens the valve in the heater 52, allowing the heated solution to enter the desorption column 53 for desorption; after the desorption is completed, if the PLC controller 1 receives the signal of the desorption temperature detection element 2 3222 reaching If the temperature of desorption temperature detection element 2 3222 is lower than the target value, PLC controller 1 will open the valve for the solution to flow from desorption column 53 into electrolytic cell 54 and close the valve for the solution to flow from desorption column 53 into solution tank 51, allowing the solution to flow into electrolytic cell 54. When PLC controller 1 receives a signal from electrolytic cell level gauge 331 (when the liquid level in electrolytic cell 54 reaches the predetermined level), PLC controller 1 will activate rectifier 432 to regulate the current in electrolytic cell 54 to electrolyze the solution. After electrolysis is complete, PLC controller 1 will open the valve in electrolytic cell 54, allowing the electrolyzed solution to enter pipe 1 between desorption pump 41 and solution tank 51 for the next desorption electrolysis process. If PLC controller 1 receives a signal that the temperature of desorption temperature detection element 2 3222 is lower than the target value, PLC controller 1 will close the valve at the entrance of electrolytic cell 54 and open the valve for the solution to flow from desorption column 53 into solution tank 51, allowing the solution to enter solution tank 51 and resume the desorption electrolysis process.

[0067] If the flow switch 323 is in the closed state and an alarm is sounded, it indicates that the desorption pump 41 is malfunctioning and the solution in the solution tank 51 cannot flow into the heater 52. At this time, the PLC controller 1 turns off the heating device 42 and stops heating the solution in the heater 52 to lower the temperature in the heater 52. At the same time, the PLC controller 1 turns off the rectifier 432 and adjusts the valve of the desorption pump 41 to a larger gear to allow the solution to be injected into the heater 52 until the liquid level of the solution in the heater 52 reaches the standard. The PLC controller 1 then turns on the heating device 42 and the rectifier 432 again to allow the entire system to operate normally. If the PLC controller 1 cannot adjust the valve of the desorption pump 41 to allow the solution to be injected into the heater 52, the PLC controller 1 will shut down the entire system to ensure the safety of the equipment and environment.

[0068] When the pressure parameter collected by the electrolytic cell pressure transmitter 332 exceeds the pressure, the PLC controller 1 will open the electric valve 431 to automatically release the pressure to ensure system safety; after the pressure drops to a certain value, the electric valve 431 will automatically close again.

[0069] When the PLC controller 1 detects that the difference between the desorption pressure transmitter 1 3211 and the desorption pressure transmitter 2 3212 is greater than the preset value (i.e., the pressure at the inlet of the desorption column 53 is abnormal), and / or detects that the difference between the desorption pressure transmitter 1 3211 and the desorption pressure transmitter 3 3213 is greater than the preset value (i.e., the pressure at the outlet of the desorption column 53 is abnormal), the PLC controller 1 will shut down the entire system to ensure the safety of the equipment and the environment.

[0070] When the desorption time reaches the set time, the PLC controller 1 will turn off the heating system, the rectifier 432, and the desorption pump 41 in sequence.

[0071] When the process parameters collected by the liquid level meter, flow meter 312, desorption pressure transmitter, and temperature detection software are abnormal, the host computer 2 will display an alarm prompt.

[0072] This achieves interlocking control of the entire system.

[0073] This system can be fully controlled by the PLC controller 1 to automatically control the process flow, and can also be manually controlled locally by on-site operators or remotely by managers to deal with various complex and sudden problems.

[0074] In summary, the utility model provides an intelligent desorption electrolysis control system, which is provided with a PLC control unit connected to a host computer, an information sensing module connected to the PLC control unit, and an information sensing module connected to the PLC control unit, wherein the information sensing module includes a solution state detection element, a desorption state detection element, and an electrolysis state detection element; the function execution module includes a solution adjustment device, a desorption adjustment device, and an electrolysis adjustment device; in this way, the liquid level, pressure, liquid flow rate and other parameters in the desorption electrolysis process can be monitored in real time, and the process can be adjusted in time to achieve safe monitoring of the operating status of the equipment in the entire system, so that the desorption electrolysis process is highly automated and rationalized, labor is reduced, work efficiency is improved, and production costs are reduced.
