Abstract：The oil and gas storage and transportation processes were characterized by the explosive Ozone environment where flammable gas and air were mixed．The zone O fan is an important device to ensure the safety of the zone O environment. This paper classified and reviewed the research progresses in the fields of narrow confined space combustion and explosion laws，flow field optimization calculation，impeler centrifugal stress and vibration，safety shaft seal technology，and explosion suppression testing for zone O fans.Five technical prospects were proposed：1） establishing an explosion test method for zone O fans was the top priority，and a closed-loop test system should be established to evaluate the explosion resistance performance；2） compared with narrow confined space combustion，the rotating structures within the fan’s interior had diferent DDT laws，which should be revealed through experiments and calculations；3）analyze the disturbance laws of the flame arresteron the flow field，and conduct acomprehensive flow fieldoptimization study to improve the ventilation performance of the fans；4） study the distribution and vibration laws of high-speed impeller stress，and propose safe stress limits and improvement methods；5） develop antiexplosion，anti-static，wear-resistant shaft seal materials and eficient seal structures. The conclusion is thatby conducting researches on key technologies，it is possble to achieve a breakthrough in domestically produced zone O fans of the same type.
