High temperature and high pressure water circular corrosion experiment system with automatic control function

Abstract

The invention relates to a high temperature and high pressure water circular corrosion experiment system, concretely relates to a high temperature and high pressure water circular corrosion experiment system with an automatic control function, which solves the problems that pressure can not be accurately controlled in simulation experiments and the like in prior art. The system comprises a pressure-reducing valve, an exhaust apparatus, a stainless steel water storage tank, a routine pump I, a filter cotton core, a high pressure pump, a buffer tank, a pH probe, a dissolved oxygen probe, a conductivity probe, a routine pump II, a heat exchanger, a preheater, a high pressure kettle, a condenser and a backpressure valve. The system is capable of accurately controlling the aquatic chemistry parameter in a circuit system, carrying out in-situ and on-line electrochemistry measurement and high temperature high pressure immersion experiments under the high temperature high pressure water circular condition. The system realizes the control by a hand-operated mode and an automatic mode, is capable of performing real time accurate measurement, record, display and control of the system parameter, and has the characteristics of high automation degree, high control precision, safety and high efficiency.

Description

technical field [0001] The invention relates to a high temperature and high pressure water circulation corrosion experiment system, in particular to a high temperature and high pressure water circulation corrosion experiment system with an automatic control function. Background technique [0002] With the rapid development of the modern economy and society, energy issues have become increasingly prominent. As a clean and efficient energy source, nuclear power is increasingly being used widely. The service environment of materials in nuclear power circuits is extremely harsh, which plays an important role in the safe and stable operation of nuclear power. The operating experience of steam generators in pressurized water reactor nuclear power plants shows that the accidents of nuclear power plants shutting down due to the rupture of steam generator tubes account for a high proportion. Therefore, it is necessary to simulate the high-temperature and high-pressure water environ...
