The utility model relates to an acetylene gas oxygen content analysis system with a pretreatment function. The system comprises a ceramic filter, an active carbon filter, a membrane filter, an online analysis instrument and a jet pump. The sampled acetylene gas is firstly filtered by a ceramic filter to remove impurities, particulate matters and part of moisture, then is filtered by an activated carbon filter to remove impurities (mainly including trace phosphine and hydrogen sulfide) and moisture to become dry acetylene gas, then is adsorbed by a membrane filter to adsorb tiny particulate matters (mainly including calcium carbide tiny particulate matters), and is adjusted by a flow meter to obtain the acetylene gas. And finally, entering a measuring chamber of the online analysis instrument for analysis. According to the utility model, the preprocessing device is arranged in front of the on-line analysis instrument, so that the authenticity and the stability of measured data are ensured, the accuracy is impr
