Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 As shown, the marine capillary force-driven containment heat export system of the present invention includes a water tank 1. The containment vessel 2 is arranged in the water tank 1. The water tank 1 is arranged around the bottom of the containment vessel. The water in the tank 1 provides sufficient cooling for the safety vessel. The water source, the water source can be deionized water.

[0023] The inventive point of the present invention is that: the outer surface of the containment vessel 2 is provided with a porous structure 3 having a capillary driving force for water, and the pores in the porous structure 3 are interconnected. The porous structure 3 in the present invention is formed by sintering micro-spherical copper particles and covers the surface of the containment vessel. The porous structure 3 l...

Abstract

The invention relates to a marine capillary force driven containment vessel heat exporting system which comprises a water tank, a containment vessel is arranged in the water tank, and the outer surface of the containment vessel is provided with a porous structure having capillary driving force on water. According to the heat exporting system, fluid is driven to flow on the surface of the containment vessel through capillary force of the porous structure on the liquid, so that heat in the containment vessel is taken away, continuous power supply to active equipment is not needed, and the safetyprotection effect can still be achieved even under the condition that a power supply is lost.

Description

technical field [0001] The invention relates to a heat device of a containment in a nuclear power plant, in particular to a capillary force-driven containment heat export system for a ship. Background technique [0002] When a loss of water accident occurs in the primary circuit of a nuclear power plant or the main steam pipe in the containment is broken, high-temperature and high-pressure coolant or steam enters the containment, causing the internal temperature and pressure to rise sharply. Measures may cause damage to the equipment in the containment vessel, threaten the sealing of the containment vessel, or even cause the containment vessel to rupture, resulting in the release of large-scale radioactive substances into the environment, resulting in serious radioactive pollution. [0003] At present, the mainstream second-generation nuclear power in operation in my country mainly adopts the containment spray system to reduce the internal pressure and temperature of the con...
