The invention relates to the technical field of spectral detection, in particular to a high-precision gas component detection device and method based on spectral measurement. The device comprises a spectrum tester, the spectrum tester is communicated with an air inlet pipe, the air inlet pipe is provided with a material mixing pipe, the material mixing pipe and the air inlet pipe form a communicated cavity, the material mixing pipe is provided with a gas mixing device, the gas mixing device comprises a driving part, the driving part is provided with a blade plate, a gas pressing plate is arranged below the blade plate, and a baffle is installed in the air inlet pipe. An air guide assembly is arranged on one side of the baffle. The communicating cavity is formed by the gas inlet pipe, the mixing pipe and the baffle, the volume of gas in the communicating cavity is changed by means of movement of the gas pressing plate, and the changed gas in the communicating cavity is rapidly mixed according to rotation of th
