The application discloses a chemical delivery system and a method for eliminating static electricity in a chemical delivery pipeline, including: a chemical reagent delivery pipe, a liquid storage device and an aerosol generating device. The liquid storage device stores the aerosol generating solution. The input end and the output end of the aerosol generating device are respectively communicated with the liquid storage device and the chemical reagent delivery pipe. The aerosol generating solution in the liquid storage device enters the aerosol generating device. The aerosol generating device converts the aerosol generating solution from a liquid state to an aerosol state. The aerosol enters the chemical reagent delivery pipe and diffuses, then it adsorbs and eliminates the charged ions in the chemical reagent delivery pipeline, thereby preventing fire or explosion from electrostatic ions encountering flammable and explosive chemical reagents.
