The invention discloses a flash detection
system which comprises a cleaning
system, a filling
system, a tank to be detected and a detection system. The cleaning system is used for picking, filling and blow-
drying cleaning liquid, the filling system is used for picking and filling detection reagents, the tank to be detected contains liquid to be detected, and the detection system is used for detecting objects to be detected. Maintenance and functions of the systems are realized by connecting the filling system, the cleaning system and the detection system through a pipeline, the detection system comprises a light-tight cylinder arranged above a detection
cell, the light-tight cylinder is overlapped with the center line of the detection
cell, a rapidly openable
shutter is arranged above the light-tight cylinder, a
photomultiplier is arranged above the
shutter, and a filling needle sequentially penetrates the
shutter and the light-tight cylinder and is suspended above the detection
cell. By the aid of the filling needle arranged above the detection cell, the detection reagents can be rapidly filled, the shutter is rapidly opened to obtain detection results, the flash detection system is applicable to flash detection, the pipeline can be blow-dried by the cleaning system capable of blow-
drying the cleaning liquid after a liquid path is cleaned, residues are avoided, and the pipeline is cleaned up.
