Pressure regulator pressure relief system for deep sea nuclear power underwater platform

Abstract

The invention discloses a pressure stabilizer relief system for a deep-sea nuclear power underwater platform, belonging to the field of deep-sea equipment. The pressure stabilizer relief system at least comprises a pressure stabilizer, a pressure relief pipeline, an exhaust manifold and a pressure relief tank; and the pressure stabilizer relief system comprises a pressure stabilizer, a pressure relief pipeline, an exhaust manifold and a pressure relief tank. Three pressure relief pipelines are connected above the voltage stabilizer, and each pressure relief pipeline is provided with an electric gate valve and a safety valve; The three pressure relief pipelines are connected with the exhaust manifold, and the exhaust manifold is connected with the pressure relief box. Water and nitrogen arearranged in the pressure relief box, and the pressure relief box is respectively connected with the spray system and the nitrogen system; One side of the pressure relief tank is part of the deep seanuclear power pressure housing; The top and bottom of the pressure relief tank are connected to the waste treatment system; The utility model solves the problem that the existing pressure stabilizer relief system needs to install an exhaust pipeline on the pressure-resistant shell, which is not conducive to the structural safety of the underwater platform; The pressure stabilizer relieving systemcan be operated reliably in deep sea, and the effect of influence on the pressure-resistant shell can be avoided.

Description

technical field [0001] Embodiments of the present invention relate to the field of deep-sea equipment, in particular to a pressure regulator pressure relief system for deep-sea nuclear power underwater platforms. Background technique [0002] The underwater manned platform is an important equipment that can carry out marine scientific research, marine resource exploration and exploitation, marine observation network construction, operation and maintenance in the deep sea for a long period of time and all-weather. [0003] In order to meet the operating requirements of numerous equipment on underwater platforms, it is necessary to provide a long-term, high-power reliable power source, and nuclear power has become a more preferred choice. The reactor primary circuit is the main component of the nuclear power plant, including pressure vessels, cores, pressurizers, pressure relief lines, steam generators and main pumps. The pressure relief system of the pressurizer is an import...

Problems solved by technology

However, when the underwater manned platform works in deep sea, the pressure of seawater outboard can reach tens of MPa. At this time, the steam discharge pressure of the regulator will be lower than the back pressure of the outboard, and the pressure relief system of the regulator cannot discharge the steam directly. to overboard

In addition, the exhaust pipeline installed through the cabin also has an adverse effect on the structural safety of the horizontal platform
