Abstract

The utility model relates to a thermal power plant condensate water regeneration resin conveying automatic identification device which is arranged on a conveying pipeline through fixing modules arranged on four sides and comprises a light source, a resin conveying window, a receiving device and a collecting module. The light source is arranged on one side of the resin conveying window and used for sending transmission light with the specific wavelength to the resin conveying window. The receiving device is arranged on the other side, opposite to the side where the light source is arranged, of the resin conveying window, and is used for receiving an optical signal formed after the transmission light passing through the resin conveying window interacts with the resin, processing the optical signal and converting the optical signal into an electric signal; the acquisition module comprises an analog-to-digital conversion unit and a signal transmission unit; the analog-to-digital conversion unit is used for acquiring a current signal and converting the current signal into a digital signal; the signal transmission unit is used for transmitting the digital signal to the digital signal analysis circuit; the four fixing modules are arranged around the resin conveying window and installed on the four side faces of the resin conveying window at equal intervals. A corresponding system is also disclosed.
