2. The starting temperature is extremely low: only 30 degrees can start the temperature transfer
4. No need for maintenance for life: plumbing equipment needs to be repaired every year, and there are still water leakage, water leakage, and dripping. No matter how good the maintenance is, the life of plumbing equipment is only six to seven years.
Therefore, it is particularly important to detect leaks in containers storing superconducting liquid. Once a leak occurs and is not found in time, it may cause harm to personal safety.

Abstract

The invention relates to a superconductive liquid container leak detection system and method. The leak detection system comprises a superconductive liquid container body, a heat source and ultraviolet light sources. The cavity of the superconductive liquid container body is filled with superconductive liquid. Composite fluorescent agent microporous materials are uniformly distributed in the superconductive liquid in a suspension manner. The composite fluorescent agent microporous materials are prepared through uniformly distributing ultraviolet ray fluorescent agent particles into a micropore carrier body. The aperture of the micropore carrier body is 10-500 nm. The weight ratio of the ultraviolet ray fluorescent agent particles and the micropore carrier body is 0.5-5:100. The ultraviolet light sources are distributed around the superconductive liquid container body. The leak detection system can carry out leak detection on narrow and small spaces and concealed areas, and can detect small-dimension leak points. The leak detection method can carry out accurate positioning on the leak points and is visual and obvious. The superconductive liquid container leak detection system and method realize the purpose of detecting whether the container leaks through a fluorescent effect, and has the advantages of being simple to operate, small in workload, safe and reliable, good in detection effect and low in cost and the like.

Description

technical field [0001] The invention relates to a leak detection system, in particular to a leak detection system and method for a container for storing superconducting liquid. Background technique [0002] The superconducting liquid has the following advantages: 1. Fast heat transfer speed: it does not use water as the heat conducting medium, but utilizes the compound chemical superconducting liquid to circulate and conduct heat conduction. Superconducting liquid has a large latent heat of vaporization (1.5 times that of water). When the superconducting liquid is heated and vaporized to produce high-energy physical changes, it can cause the hot gas to heat up rapidly. 2. The starting temperature is extremely low: only 30 degrees can start the temperature transfer. And the transfer temperature of water must exceed or reach 100 degrees, the water temperature rises very slowly, and the transfer is even slower. Generally, it takes 1 to 2 hours to reach room temperature after ...
