Abstract

The invention relates to a device for sterilizing pipeline fluid by using a germicidal light source, which is arranged in a circulating fluid pipeline, and includes: a pipe body, two transition pipes, an impeller rod, a permanent magnet, an induction coil and a germicidal light source; When the fluid flows from one end to the other end of the tube, the fluid drives the impeller rod to rotate and induces permanent magnets and induction coils to generate electricity. The germicidal light source is used to irradiate and sterilize the fluid; while the fluid is continuously circulating, the device irradiates uninterruptedly.
