The utility model provides a device for detecting the particle size of lignin nano-particles on line, which comprises a laser transmitter used for transmitting a laser beam; the reaction tank is positioned on the laser beam emitted by the laser emitter; the first feeding pipe is communicated with the reaction tank and is used for adding a sample to be detected into the reaction tank; the second feeding pipe is communicated with the reaction tank, and the second feeding pipe is used for adding water into the reaction tank; the laser receiver is positioned at the downstream of the reaction tank and is used for converting the received laser into an electric signal; and the processor is electrically connected with the laser receiver and is used for processing the electric signal. According to the device, the particle size of the lignin nanoparticles can be detected while the lignin nanoparticles are prepared, compared with a laser particle analyzer, the lignin nanoparticles do not need to be prepared in advance,
