The invention provides an open type multi-reflection White cell infrared spectrum analysis system, which is suitable for smoke chamber gas detection and comprises a smoke chamber, a Fourier infrared spectrometer, an industrial personal computer, a multi-reflection White cell, a reflector, a pipeline, a lifting device and the like. Wherein the multi-reflection White cell comprises a primary mirror component, a secondary mirror component, a secondary mirror adjusting component, an incident parabolic mirror adjusting component, an emergent parabolic mirror adjusting component and the like. The coupling mode of the spectrometer and the smog chamber mainly comprises an incident mode, an emergent mode and a spectrometer installation mode. According to the incidence mode, a plane mirror in a sample bin is adjusted, so that modulated light is converged at a specific angle and enters a smog chamber; the emergent light is guided back to the optical axis of the sample bin through turning of a plurality of plane mirrors;
