Problems solved by technology

[0005] The purpose of this application is to provide a method and device for regeneration of the positive bed in the condensate polishing system of a nuclear power plant, to solve the problem that the conditions prepared at the beginning of automatic logic operation are easy to change when it is used, resulting in the failure of regeneration and the automatic regeneration logic of the positive bed stops halfway. After that, you can't continue to regenerate, you can only restart the problem

Abstract

The invention belongs to the technical field of nuclear power station water treatment, and relates to a method and device for regenerating a cation bed of a condensate polishing system of a nuclear power station According to the method, the regeneration process is divided into four logic units according to four steps, an independent starting condition is formulated for each logic unit, for example, starting of the next logic unit is not affected when a certain logic unit is stopped and quits due to various reasons during execution; fine treatment cation bed regeneration set through the method is high in practicability and low in cost; and regeneration of the fine treatment system and related operation of a desalted water preparation system are compatible and do not conflict, and the automation level of the system is improved.

Description

technical field [0001] The application belongs to the technical field of nuclear power plant water treatment, and in particular relates to a method and device for regenerating a positive bed in a condensate polishing treatment system of a nuclear power plant. Background technique [0002] A nuclear power plant unit is equipped with a set of condensate fine treatment system, which is used to purify the condensate water quality and remove metal impurities such as metal corrosion products and ion impurities. The condensate fine treatment system includes a mechanical filtration system, an ion exchange system, an in vitro regeneration system, and a waste water discharge system. Among them, the mechanical filtration system includes five cation beds, and the ion exchange system includes five mixed beds. [0003] The five positive beds and five mixed beds of the condensate polishing system operate normally with four uses and one standby. The fine treatment anode bed is filled with...
