[0023] An upper column regeneration endpoint detector 8 is arranged on the upper side of the upper column 6 of the resin exchange column, and an upper column failure endpoint detector 9 is arranged on the lower side of the upper column 6 of the resin exchange column. The upper column regeneration endpoint detector 8 and the upper column failure endpoint detector 9 are connected to a control system 13; a lower column regeneration endpoint detector 10 is arranged on the upper side of the lower column 7 of the resin exchange column, and a lower column failure endpoint detector 11 is arranged on the lower side of the lower column 7 of the resin exchange column, and the lower column regeneration endpoint detector 10 and the lower column failure endpoint detector 11 are connected to the control system 13; a partition is arranged between the lower column 7 of the resin exchange column and the upper column 6 of the resin exchange column.

[0024] The specific working process of the present invention is:

[0025] The present invention divides the cation exchange column into a lower column 7 of the resin exchange column and an upper column 6 of the resin exchange column, wherein the lower column 7 of the resin exchange column and the upper column 6 of the resin exchange column adopt a working mode of one for backup and one for use, and the performance of the resin is judged according to the color of the resin by an upper column regeneration endpoint detector 8, an upper column failure endpoint detector 9, a lower column regeneration endpoint detector 10 and a lower column failure endpoint detector 11, and the upper column 6 of the resin exchange column is used for explanation below:

[0026] Desalted water and industrial hydrochloric acid are mixed in the pipeline mixer 3 and then enter the regeneration liquid preparation box 1. Under normal circumstances, the water sample enters the upper column 6 of the resin exchange column for treatment and then enters the drainage pipe. The color of the lower side of the upper column 6 of the resin exchange column is detected by the upper column failure endpoint detector 9 to determine whether the upper column 6 of the resin exchange column has failed. When the upper column 6 of the resin exchange column has failed, the water sample is switched to the lower column 7 of the resin exchange column, and the regeneration liquid in the regeneration liquid preparation box 1 is passed into the upper column 6 of the resin exchange column to regenerate the upper column 6 of the resin exchange column. The upper column regeneration endpoint detector 8 detects the color of the upper side of the upper column 6 of the resin exchange column to determine whether the regeneration of the upper column 6 of the resin exchange column is completed. When the regeneration of the upper column 6 of the resin exchange column is completed, the regeneration liquid is switched, and flushing water is passed into the upper column 6 of the resin exchange column to flush the upper column 6 of the resin exchange column, wherein the flushing drainage and regeneration drainage discharged from the upper column 6 of the resin exchange column enter the drainage pipe. After flushing, the upper column 6 of the resin exchange column is in a standby state.

[0027] When the resin exchange column needs to be inspected and cleaned, the unit has just been started, or in the extreme case that the upper column 6 of the resin exchange column fails and the lower column 7 of the resin exchange column has not been regenerated, the water sample enters the electric regeneration ion exchanger 12 for processing. The electric regeneration ion exchanger 12 has a fast stabilization time and is suitable for monitoring the hydrogen conductivity of each water vapor sample during the startup of the unit. In addition, the control system 13 uses a hydrogen conductivity meter to detect in real time whether the hydrogen conductivity in the drainage pipe is qualified.

[0028] In addition, the acidity of the regeneration liquid at the outlet of the pipeline mixer 3 is detected by the acidity detector 4, and the flow rate of the desalted water and the flow rate of the industrial hydrochloric acid are controlled according to the acidity of the regeneration liquid at the outlet of the pipeline mixer 3, so that the concentration of the regeneration liquid is 4% to 6%. In addition, the liquid level information detected by the lower liquid level detector 2 and the upper liquid level detector 5 is used to control the on-off of the first three-way valve to realize the control of the regeneration liquid level in the regeneration liquid preparation box 1. The regeneration liquid flow rate output by the regeneration liquid preparation box 1 is 10L / h.
