Abstract
A device and a method for producing high-purity nano molybdenum trioxide are provided. The device comprises a raw material bin (1), a feeding machine (2), a subliming furnace (7), a first vent tube (24), a second vent tube (25), a spraying device (23) and a filtering assembly. The sublimated molybdenum trioxide is cooled with clean and dehumidified air so as to finally obtain the nano molybdenum trioxide, and the recycling mode is reliable, pollution-free and high in efficiency.

A device for producing high-purity nano molybdenum trioxide, comprising a raw material bin (1), a feeding machine (2), a subliming furnace (7), a first vent tube (24), a second vent tube (25), a spraying device (23) and a filtering assembly (12), wherein the raw material bin (1) is in communication with the feeding machine (2);
- the feeding machine (2) is in communication with the lower side of the subliming furnace (7);
- the upper side of the subliming furnace (7) is in communication with the horizontally arranged first vent tube (24);
- the tail end of the first vent tube (24) is in communication with the vertically arranged second vent tube (25);
- the second vent tube (25) is in communication with a recoverer (13);
- a finished product bin (11) is arranged below the recoverer (13);
- the filtering assembly (12) is arranged at a part, in the recoverer (13), in communication with the second vent tube (25);
- the spraying device (23) is arranged at the connecting part of the first vent tube (24) and the second vent tube (25);
- the spraying device (23) is connected to a dispersing agent port (21) and a compressed air port (22);
- the nozzle direction of the spraying device (23) is coaxial with the axis of the second vent tube (25);
- and a clean air inlet (10) is provided in the first vent tube (24).
A method for producing high-purity nano molybdenum trioxide, comprising the steps of taking pure molybdenum trioxide as a raw material, delivering the raw material into the subliming furnace (7) through the feeding machine (2), controlling a temperature of the subliming furnace (7) at 1100° C. to 1160° C. and subliming the raw material, starting a propulsion motor (19) and a rotary motor (18), accessing clear air with a water content less than 30% from the clean air inlet (10) at 10° C. to 18° C. to guarantee the temperature of the first vent tube (24) at 75° C. to 85° C., starting the spraying device (23) to eject the spray with dispersing agent, spraying the raw material into the recoverer for filtering and collecting the raw material, and filtering the air through the filter and entering the raw material into the deionized water pool (16).
