[0045] Please refer to the attached Figure 1 , 4As shown in Figures 5 and 8, in another preferred embodiment of the present invention, a pre-flushing component 31 is symmetrically provided on the top of the regeneration liquid storage tank 30, and the pre-flushing component 31 includes a pre-flushing tank 311 provided on the top of the regeneration liquid storage tank 30, and a first electrically controlled valve 312 provided on the side wall of the pre-flushing tank 311, and the first electrically controlled valve 312 is connected to the delivery pipeline 213 through a pipeline, and an air flow flushing component 32 is provided on the top of the regeneration liquid storage tank 30, and the air flow flushing component 32 includes an air storage tank 321 provided on the top of the regeneration liquid storage tank 30, an air compressor 322 provided on the top of the air storage tank 321 and the execution end is connected to the air storage tank 321, and two second electrically controlled valves 323 are symmetrically provided on the side wall of the air storage tank 321, and the second electrically controlled valve 323 is connected to the delivery pipeline 213 through a pipeline.

[0046] It should be noted that, in this embodiment, when the ion exchange column is regenerated, the pre-flushing component 31 first pre-flushes the pipeline of the ion exchange column to be regenerated with the regeneration liquid, and the air flow flushing component 32 flushes the pipeline of the ion exchange column to be regenerated with the air flow. After completion, the gas storage tank 321 delivers pressurized gas to one of the cavities 302 through the pipeline, so that the regeneration liquid enters the delivery pipeline 213;

[0047] Furthermore, when the pre-flushing component 31 is working, the first electrically controlled valve 312 is opened, and the gas storage tank 321 delivers pressurized gas to one of the pre-flushing boxes 311 through a pipeline, and the regeneration liquid in the pre-flushing box 311 enters the delivery pipeline 213 and returns to the other pre-flushing box 311 after flushing the pipeline;

[0049] Furthermore, when the regeneration liquid is transported, the controller receives the flow data of the flow sensor 2132 and triggers the regulating valve 2131 to make the flow reach the set value. The controller receives the temperature data of the temperature sensor 341 and triggers the heater 342 until the temperature data reaches the set value. The heater 342 facilitates rapid heating of the regeneration liquid through the heat-conducting column 343, turns on the transmission motor 331, and the transmission motor 331 drives the stirring turntable 332 to rotate, so as to facilitate the homogenization of the solute of the regeneration liquid in the regeneration liquid storage tank 30.

[0052] A total of one spare ion exchange column 101 and 4N+2 three-way solenoid valves are provided to realize online automatic regeneration of N working ion exchange columns 201, and N is recommended to be less than or equal to the time interval for regeneration of the ion exchange column divided by half of the time required for regeneration;

[0053] During normal operation, water is introduced into the water inlet switching component 21, and the water flows sequentially through the third three-way solenoid valve 212 and the second three-way solenoid valve 211 in the water inlet switching component 21 into the second ion exchange box 20, and after the reaction, the water is discharged to the detection equipment through the second three-way solenoid valve 211 and the third three-way solenoid valve 212 in the water discharge switching component 22 to perform hydrogen conductivity detection;

[0054] When one of the working ion exchange columns 201 is regenerated, the third three-way solenoid valve 212 in the water inlet switching component 21 corresponding to the working ion exchange column 201 directs the water flow into one of the transmission pipes 13, and the water flows into the first ion exchange box 10 through the transmission pipe 13 and one of the first solenoid tees 12.

At the same time, the regeneration liquid in one of the cavities 302, such as hydrochloric acid, enters the second ion exchange box 20 through the delivery pipe 213 and the second three-way solenoid valve 211 in the water inlet switching component 21 and flushes and regenerates the working ion exchange column 201. The discharged regeneration liquid returns to the other cavity 302 through the second three-way solenoid valve 211 in the drainage switching component 22 and the delivery pipe 213;

[0055] When the spare ion exchange column 101 is regenerated, the regeneration liquid in one of the cavities 302 enters the first ion exchange box 10 through one of the delivery pipes 213 and the first electromagnetic tee 12 to flush and regenerate the spare ion exchange column 101, and the discharged regeneration liquid returns to the other cavity 302 through another first electromagnetic tee 12 and the delivery pipe 213;

[0057] The cyclone contact component 11 facilitates the liquid flowing through to fully contact the ion exchange column, and the ion exchange column installation device 40 facilitates the rapid disassembly and assembly of the ion exchange column;

[0058] Taking the first ion exchange box 10 as an example, after the liquid enters the first ion exchange box 10, it spirals down under the action of the spiral guide plate 111 so as to fully contact with the spare ion exchange column 101;

[0059] Taking the replacement of the spare ion exchange column 101 as an example, the driving cylinder 43 drives the top cover 41 to move upward so that the spare ion exchange column 101 is moved out of the first ion exchange box 10. At this time, the spare ion exchange column 101 can be pulled outward, and the slider 422 drives the top of the spare ion exchange column 101 to move out of the top cover 41. At this time, the fastening screw 424 can be loosened to remove the spare ion exchange column 101, and the new spare ion exchange column 101 is replaced and the spare ion exchange column 101 is installed and fixed according to the disassembly steps;

[0060] When the ion exchange column is regenerated, the pre-flushing component 31 first pre-flushes the pipeline of the ion exchange column to be regenerated with the regeneration liquid, and the air flow flushing component 32 flushes the pipeline of the ion exchange column to be regenerated with the air flow. After completion, the gas storage tank 321 delivers pressurized gas to one of the cavities 302 through the pipeline, so that the regeneration liquid enters the delivery pipeline 213;

[0061] When the pre-flushing component 31 is working, the first electric control valve 312 is opened, and the gas storage tank 321 delivers pressurized gas to one of the pre-flushing boxes 311 through the pipeline. The regeneration liquid in the pre-flushing box 311 enters the delivery pipeline 213 and returns to the other pre-flushing box 311 after flushing the pipeline.

[0062] The air compressor 322 can deliver pressurized gas to the gas storage tank 321, open the second electric control valve 323, and the pressurized gas in the gas storage tank 321 enters the delivery pipeline 213 to push the pre-flushing liquid remaining in the pipeline to another pre-flushing box 311;

[0063] When the regeneration liquid is transported, the controller receives the flow data of the flow sensor 2132 and triggers the regulating valve 2131 to make the flow reach the set value. The controller receives the temperature data of the temperature sensor 341 and triggers the heater 342 until the temperature data reaches the set value. The heater 342 facilitates rapid heating of the regeneration liquid through the heat-conducting column 343, turns on the transmission motor 331, and the transmission motor 331 drives the stirring turntable 332 to rotate, so as to facilitate the homogenization of the solute of the regeneration liquid in the regeneration liquid storage tank 30.

[0064] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
