Controllable atmosphere hydrogen introduction reduction furnace

The invention provides a controllable atmosphere hydrogen feeding reduction furnace. The controllable atmosphere hydrogen feeding reduction furnace comprises a reduction furnace body, a hydrogen inlet pipeline arranged at the tail of the reduction furnace body, three hydrogen outlet pipelines arranged at preset positions in the middle of the reduction furnace body, a pressure meter arranged in the reduction furnace body, gas exhausts arranged on outlets of the hydrogen outlet pipelines and a controller. The gas exhauster is used for controlling the hydrogen outlet flow of the three hydrogen outlet pipelines; the pressure gauge is used for detecting the pressure in the reduction furnace; through pressure feedback, the controller dynamically adjusts forward and reverse hydrogen modes of the reduction furnace. And forward and reverse hydrogen conditions in the furnace can be adjusted. By means of the mode of large hydrogen flow and middle hydrogen output, a large amount of water in hydrogen can be taken away, th
