Thermal power plant fault judgment device and detection method using same

Abstract

The invention relates to the technical field of thermal power plants, in particular to a thermal power plant fault judgment device and a detection method using the device. The thermal power plant fault judgment device comprises a cooling tower, a circulating pool arranged in the cooling tower and a liquid circulating device arranged on the cooling tower, and a first detection device used for detecting impurities in the cooling tower is arranged in the circulating pool. The first detection device comprises a first sieve plate installed in the circulating pool, a gravity sensor installed on the first sieve plate and a second sieve plate arranged in the circulating pool, the second sieve plate and the first sieve plate are sequentially arranged in a spaced mode in the vertical downward direction, and filter holes are formed in the second sieve plate and the first sieve plate. The two ends of the gravity sensor abut against the second sieve plate and the first sieve plate respectively. The thermal power plant fault judgment device and the detection method have the effects that the situation that sundries are easily accumulated in the circulating pool can be reduced, and meanwhile, the fault hidden danger of reusing circulating water is reduced.

Description

technical field [0001] The present application relates to the technical field of thermal power plants, in particular to a thermal power plant fault judgment device and a detection method using the device. Background technique [0002] At present, thermal power plants generally refer to thermal power plants, thermal power plants, etc., which are factories that use coal, oil, natural gas and other solid and liquid fuels to convert heat energy into kinetic energy to produce electrical energy. The cooling tower is a large thin-shell structure common in thermal power plants and nuclear power plants. In order to save water, a circulating cooling water system needs to be built for power plants built in areas where water sources are not very sufficient, so that the hot water discharged from the cooler It can be reused after cooling in it. During the use of the cooling tower, it is necessary to use a fault judgment device to detect the normal operation of the cooling tower and ensur...

AI Technical Summary

Problems solved by technology

In view of the above-mentioned related technologies, the inventor believes that there is a defect that debris is easy to accumulate in the circulating pool, which leads to a large potential failure of circulating water reuse.
