Trace pesticide residue detection device based on surface enhancement technology and use method of trace pesticide residue detection device

The invention relates to the technical field of drug residue detection, in particular to a trace pesticide residue detection device based on a surface enhancement technology and a use method of the trace pesticide residue detection device. The detection device comprises a Raman spectrometer, an extraction tank, a heater, a flash tank, a detection pipe made of a transparent material, a circulating pump and valve pipelines connecting the detection pipe and the circulating pump. According to the invention, the detected object is not broken, so that irrelevant components of the detected object are eliminated, and the surface of the detected object is circularly flushed by the extracting agent, so that drug residues can be fully dissolved in the extracting agent, the concentration of the drug residues in the extracting agent is improved, and the use of a reinforcing agent is reduced. Meanwhile, the flash tank can concentrate the extraction liquid, trace samples can be detected quickly and conveniently, and the det
