Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The following description is only for demonstration and explanation, and does not limit the present invention in any form.

[0034] Such as figure 1 As shown, the internal cooling water system of the generator at the operation site of a large generator has an internal cooling water tank 1, an internal cooling water pump 2, a cooler 5, and a small mixed bed 8. The internal cooling water tank 1 is connected to the internal cooling water pump 2, and the internal cooling water pump 2 is connected to the The cooler 5 is connected, the cooler 5 is connected with the small mixed bed 8, and the small mixed bed 8 is connected with the internal cooling water tank 1, so as to realize the online ammoniation and internal regeneration treatment of the resin in the small mixed bed of the internal cooling water of the generator.

Abstract

The invention discloses a small mixed bed resin online ammoniation and in vivo regeneration technology for generator internal cold water treatment. A power plant generator internal cold water system is used to realize small mixed bed resin online ammoniation and in vivo regeneration, so the disadvantages of time consumption and labor consumption for resin in vitro separation and in vitro regeneration are overcome, and the running time and the regeneration cycle of the resin are prolonged. The small mixed bed resin online ammoniation and in vivo regeneration technology allows the pH value of internal cold water to be 8.0-9.0 for a long term, the electric conductivity to be smaller than 2[mu]S / cm and the copper content of the internal cold water to be smaller than 10[mu]g / L and far lower than a national standard requirement of 40[mu]g / L or less under small mixed bed individual running conditions without technologic reconstruction or arrangement of extra internal cold water cold water treatment devices.

Description

technical field [0001] The invention relates to the technical field of generator internal cooling water treatment, in particular to a small mixed bed resin online ammoniation and in vivo regeneration process for generator internal cooling water treatment. Background technique [0002] Generator cooling water system is an important system, if the supervision and control of cooling water treatment is not effective, it will affect the safe and normal operation of the generator. [0003] Generators of 200MW and above in my country are equipped with H-type (R-H / R-OH) small mixed bed on the internal cooling water bypass. The small mixed bed is filled with hydroxide-type anion resin (R-OH) and hydrogen-type cation resin (R-H). During operation, part of the internal cooling water passes through the small mixed bed continuously to remove impurities in the internal cooling water, and the effluent returns to the internal cooling water. . This treatment method can ensure that the cond...
