Comprehensive sampling system for liquid waste treatment system of nuclear power plant

Abstract

The invention relates to a comprehensive sampling system for a liquid waste treatment system of a nuclear power plant. The system includes an in situ sampling box (1), and a sampling pipeline for distillate and heated steam condensate water and a sampling pipeline for condensate liquid, which are connected to the in situ sampling box (1); and a movable type cooler (2) is arranged on the pipeline connecting the sampling pipeline for distillate and heated steam condensate water and the in situ sampling box (1). The invention uses the in situ sampling box as the main body and employs a centralized layout design; and through multi-functionalization of the in situ sampling box, sampling of different liquids under different circumstances can be completed, and cleaning and sweeping can be conducted after the sampling. At the same time, the system can reduce manpower cost required by cleaning, avoid unnecessary contact of the operator with sampling liquid and the sampling box with high radioactive level, so as to protect the operator function.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant waste liquid treatment, and in particular relates to a comprehensive sampling system used in a nuclear power plant waste liquid treatment system. Background technique [0002] Sampling and analysis of waste liquid in the nuclear power plant waste liquid treatment system is an important basis for judging the effect of waste liquid treatment. Due to the use of evaporation and concentration treatment, if the general sampling pipeline design is followed, there is a risk of high temperature in the secondary steam condensate, and the risk of containing Boron concentrated solution remaining in the sampling pipeline is easy to cause pipeline crystallization, and sampling is not representative due to the concentrated solution remaining in the pipeline. [0003] The title of the invention is "A Water Quality Automatic Analysis and Sampling System" (Application No. CN201220175432.2, application d...
