Problems solved by technology

[0004] When performing a leak detection operation on a boiler, it is generally necessary to stop the boiler for inspection. The commonly used leak detection methods include visual inspection or hydraulic leak detection. It is easy to cause missed inspection of equipment; using water pressure leak detection, the actual operation on site is complicated, and there are certain requirements for water quality, water temperature, boosting method, boosting equipment, etc., and in the event of a slight leak, the leak point is not easy to be found

Abstract

The invention relates to a boiler leak detection system and method. The leak detection system comprises a boiler and ultraviolet light sources. A cavity of the boiler is filled with a water body provided with composite fluorescent agent microporous materials. The composite fluorescent agent microporous materials are uniformly distributed in the water in a suspension manner. The composite fluorescent agent microporous materials are prepared by uniformly distributing ultraviolet ray fluorescent agent particles into a micropore carrier, wherein the aperture of the micropore carrier is 10-500 nm; and the weight ratio of the ultraviolet ray fluorescent agent particles and the micropore carrier is 0.5-5:100. The ultraviolet light sources are distributed around the boiler. The method can realize the purpose of detecting whether leakage exists 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; and meanwhile, the purpose of realizing on-line leak detection can also be realized.

Description

technical field [0001] The invention relates to a leak detection system, in particular to a boiler leak detection system and method. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers, which are mainly used in daily life, ...
