Description

Technical Field

[0001] This utility model relates to the field of resin regeneration technology, and in particular to a resin regeneration device for the power industry. Background Technology

[0002] In the power industry, online hydrogen conductivity meters are key instruments for chemical monitoring in thermal power plants, used to monitor the water and steam quality in critical monitoring areas such as feedwater and steam. A key factor affecting the accuracy of online hydrogen conductivity meters is the regeneration rate of the resin, and the decisive factor affecting the regeneration rate is the regeneration method. Furthermore, the quality of the stator cooling water directly affects the operational safety and lifespan of the generator. Long-term substandard stator cooling water quality can cause corrosion of the generator stator copper wires and blockage of the stator cooling water channels, increasing maintenance frequency, shortening generator lifespan, and posing significant safety hazards. Therefore, it is necessary to replace the resin as soon as possible. Currently, the small mixed bed devices for stator cooling water in power plants use a ready-to-use resin, which needs to be replaced after it fails and cannot be reused. Replacing the resin for one unit costs tens of thousands of yuan.

[0003] Some power companies use an external static immersion regeneration method for the effective ion exchanger resin used to measure hydrogen conductivity. However, this method results in a low resin regeneration rate (generally around 60%), which distorts the hydrogen conductivity measurement results and fails to reflect the true state of water and steam indicators. This leads to deterioration of water and steam quality and poses a threat to the safe operation of the unit. Therefore, this utility model proposes a resin regeneration device for the power industry to solve the problems existing in the prior art. Utility Model Content
