Further, described deoxidier is metallic catalyst, described metallic catalyst in can the catalysis deaerated oxygen and the oxygen in some gaseous oxygen compounds.
Further, described metallic catalyst is more than one in Nanometer Copper, Nano Silver and Technique of Nano Pd.
Further, described importing also is provided with adsorbent in the chamber, is used for some organic matters of absorbed air.
Further, described adsorbent is active carbon.
Further, described deicer is molecular sieve, and the molecular sieve water absorbing capacity is strong, and can not introduce active impurity.
Further, exit, described derivation chamber arranges screen pack, described screen pack with carry secretly in gas mechanical admixture remove.
Further, described heat exchanger comprises die cavity, is arranged on the thermal medium in die cavity, the thermal medium entrance that is arranged on the die cavity lower surface, the thermal medium outlet that is arranged on the die cavity upper surface and the tube side that is coated by thermal medium, one end of described tube side communicates with importing the chamber, and the other end communicates with the derivation chamber.
Further, described thermal medium is high-temperature steam or conduction oil.
Further, described tube side is two tube sides or quadritube-pass.
Technical scheme that the utility model provides can guarantee the anhydrous and oxygen-free Du Genggao in reactor on the one hand, helps the carrying out that react and the yield of product; On the other hand, the inert gas reusable edible in reactor has reduced outer amount for inert gas and the amount of combustion gas, reduces production costs and environmental protection more.
