This regeneration method has the following defects: First, this regeneration method is cumbersome to operate, and it belongs to a static regeneration method. The hydrogen-type cation exchange resin with a low rate of hydrogen-type cation exchange resin is used to measure the hydrogen conductivity, resulting in a low measurement value, resulting in inaccurate measurement results, which in turn leads to inaccurate water vapor quality supervision

Abstract
The invention discloses a dynamic regeneration device for a hydrogen type cation exchange resin column. The dynamic regeneration device comprises an acid liquor storage tank, a demineralized water tank, an acid liquor outlet pipe, a demineralized water outlet pipe, a regeneration liquid inlet and outlet header pipe, a regeneration resin outlet header pipe, a blow-off pipe, a regeneration resin inlet and outlet branch pipe, cation exchange resin columns, a regeneration resin outlet header pipe and an emptying pipe. According to the regeneration device, by arranging the acid liquor storage tank, the demineralized water tank and the cation exchange resin columns, dynamic regeneration of hydrogen type cation exchange resin is achieved, the multiple cation exchange resin columns are arranged, hydrogen type cation exchange resin in all the cation exchange resin columns can be regenerated at the same time, on-site real-time monitoring is not needed, the regeneration efficiency is high, the regeneration rate is also high, the repeated utilization rate of resources is improved, the accuracy of the hydrogen conductivity measurement value of the sample water is ensured, and the accuracy of water vapor quality supervision is ensured. In addition, the invention also discloses an operation method of the regeneration device, the operation is simple and convenient, and the device is convenient for any person to operate and worthy of wide popularization.
Description
technical field [0001] The invention relates to a regeneration device, in particular to a hydrogen-type cation exchange resin column dynamic regeneration device and an operation method thereof. Background technique [0002] According to the requirements of GB / T 12145-2016 "Water Vapor Quality of Thermal Power Generation Units and Steam Power" and DL / T 246-2015 "Guidelines for Chemical Supervision", real-time monitoring and measurement of water vapor quality is required. Among them, the measurement of hydrogen conductivity is the most basic supervision item of water vapor quality, and before measuring the hydrogen conductivity, the sample water needs to flow through the hydrogen-type cation exchange resin column to remove impurity cations. As the measurement continues, the resin in the hydrogen-type cation exchange resin column will become invalid due to the adsorption of impurity cations, and the invalid cation exchange resin needs to be regenerated. [0003] The regenerati...
