The course of work and principle to the present invention exemplified by using on-gaseous passivator are described as follows：
Lithium ingot is removed after packaging, adds dry molten lithium tank 5, and lithium metal protection gas is filled after vacuumizing, in the present embodiment,
Lithium metal protection gas uses argon gas.Start heater 4, by heating lithium metal to melting；Then argon pressurization is used in molten lithium tank 5
0.005~0.1Mp, liquid metal lithium is entered in passivation tank 7 by conveyance conduit 6 through valve 8, in passivation tank 7 now
It is formed with cooling passivation air-flow.Conveyance conduit 6 and valve 8 need heating and thermal insulation, and the temperature for making the exit of conveyance conduit 6 is 200
~800 DEG C；The high-temperature metal lithium liquid gone out from the outlet of conveyance conduit 6 drip enters centrifugal atomizer 9, and centrifugal atomizer 9 is by a high speed
Motor 10 drives, and the rotating speed of high-speed electric expreess locomotive 10 is up to 1~80,000 revs/min.High-temperature metal lithium liquid is atomized into carefully by centrifugal atomizer 9
Micro- lithium metal droplet distribution falls.The cooling passivating gas being passivated simultaneously in tank 7 flows through air exhauster 13 and is pressurized, through cooler II 15
Cooling, into passivator atomizer 17, enters air feed pipe after the passivator of steam form after atomization is mixed into cooling passivation air-flow
16, through being discharged for wind tube outlet in the bottom of passivation tank 7, control the exit cooling of air feed pipe 16 blunt by adjusting cooler II 15
The temperature for changing air-flow is 0~80 DEG C.In the presence of air exhauster 13, cooling passivation air-flow slowly equably rises, under scattered
The trickle lithium metal droplet formation convection current fallen, trickle lithium metal drop is frozen into metal in the presence of cooling passivation air-flow
Lithium microballoon, while forming diaphragm, acquisition passive metal on surface with the passivator reaction of steam form in cooling passivation air-flow
Lithium microballoon.Passive metal lithium microballoon is sieved by being passivated the sifter 2 that the discharging opening of the bottom of tank 7 is fallen into argon gas glove box
Point, the product of particle diameter falls into collecting box 1 needed for obtaining.Collecting box 1 can take out through the transition hatch door 18 on argon gas glove box 3.
Above-mentioned cooling passivation air-flow is that the lithium metal protection gas incorporation passivator in passivation tank is formed, and passivator is used for
Lithium metal microsphere surface is passivated, can be using phosphoric acid class, phosphoric acid ester, sulfuric acid, thio-alcohol, type siloxane, fluorine-containing
Compound and atoleine etc., it would however also be possible to employ the gas such as carbon dioxide and oxygen mix.If using gaseous state passivator, only
Gaseous state passivator need to be directly filled with to passivation tank, gaseous state passivator is mixed with the lithium metal protection gas in tank, followed in air-flow cooling
Cooling passivation air-flow is formed in the presence of loop system, now the air-flow cooling recirculation system does not include passivator atomizer 17.
If using on-gaseous passivator, it is necessary to which after on-gaseous passivator is atomized, passivator atomizing steam is added into lithium metal protection
Gas, forms cooling passivation air-flow in the presence of air-flow cooling recirculation system, and now the air-flow cooling recirculation system should be wrapped
Include passivator atomizer 17.Lithium metal protects gas that the inertia or stabilizing gas not with lithium metal reaction such as argon gas can be used.
