[0013] Example 1: Regeneration method of resin in continuous electric desalination membrane stack
[0014] There are six sets of CEDI devices in the boiler make-up water workshop of 2×300MW generating units in Taiyuan Iron and Steel Energy Power Plant. After the operation fails, this method is used to regenerate, and the voltage is significantly reduced, and the effect is obvious. The following is an example of the No. 6 CEDI device to introduce the regeneration method:
[0015] The membrane stacks of No. 6 CEDI device are divided into 6 groups, the first group, the third group, and the fifth group each have 5 membrane stacks, the second group, the fourth group, and the sixth group each have 6 membrane stacks, a total of 33 membrane stacks.
[0016] The operating parameters at the initial stage of commissioning are as follows:
[0017] .
[0018] After the resin fails, the resistance of the membrane stack increases, the operating voltage increases, and the conductivity i...
