Detailed description of the invention
Being described principle and the feature of utility model below in conjunction with accompanying drawing, example is served only for explaining that this practicality is new
Type, is not intended to limit the scope of utility model.
Embodiment 1: see Fig. 1, a kind of metallic catalyst reduction apparatus, it is characterised in that: bottom reduction furnace 1 and top
End socket is all filled with bulk drying agent 8, and end socket can be taken off by flange 9 and add before operation the object of needs reduction,
Being passed through nitrogen by nitrogen inlet 6 before normal work and purged by the air in reduction furnace 1 clean, reduction process is simultaneously with nitrogen and hydrogen
The gaseous mixture of gas does reducing atmosphere, and nitrogen inlet 6 is passed through nitrogen, is passed through hydrogen with hydrogen inlet 7, and furnace body wall is provided with electrical heating
System 2, is simultaneously provided with heat-insulation layer 4 and thermal insulation board 5 ensures reduction temperature, and the reduction process moment observes the change of moisture analyser 10
Change, when not analyzing moisture, it is possible to determine that reaction in furnace terminates, close the valve before moisture analyser, close hydrogen and enter
Mouth 7, slowly strengthens the valve of nitrogen inlet 6, and the nano metal after reducing with nitrogen is purged to fill guarantor by discharge nozzle 11
Protecting in the oil sump 13 of oil 14, this metallic catalyst is in the protection of nitrogen and protection oil all the time, and it is optimal that activity keeps.
Described nitrogen inlet 6 and hydrogen inlet 7 use nitrogen upper hydrogen under design, owing to density of nitrogen is more than hydrogen
Air tightness so that reduction object is in nitrogen guard mode all the time, and desiccant 8 is the material that gas easily passes through.
Described electric heating system 2 feeds back with thermocouple thermometer 3 and regulates temperature.
Described oil sump 13 is provided with agitator 12 can be with dispersed metallic catalyst.
The foregoing is only standards Example of the present utility model, not in order to limit this utility model, all in this practicality
Any amendment made within novel spiritual principles, equivalent, improvement etc., should be included in protection model of the present utility model
Within enclosing.
