However, the industrial preparation of gas usually contains a small amount of some reactants, intermediates and some impurities in water and air, which cannot meet the use requirements. The existing high-purity gas purification device mainly heats the raw gas and then catalyzes the reaction, and then uses deoxidizer to deoxidize the gas after cooling, and finally completes the purification through the filter. The whole device needs to add an additional control system to control the temperature, pressure and flow rate in the device, which is complex and costly. In addition, although two groups of deoxidizing units are set alternately, but in the case that one group has failed and the other group has not been completely regenerated or has failed, the gas cannot be continuously purified. At the same time, there is no component for pretreatment of the whole device, which causes the raw gas to be contaminated by the residual gas in the device at the beginning of purification, not only causing waste of raw gas, but also making the waiting time for normal operation of the device too long.
