But in room 14, then flowed out by cooling gas escape pipe 13, play and carry out cooling effect to gas distributor disk 9, avoid methane or
Acetylene is cracked into carbon because temperature is excessively high with the mixed gas of nitrogen or inert gas in gas distributor disk 9 and in turn results in blocking,
Cause methane or acetylene cannot be by the ventilation of 4 bottom of ventilation nozzle 8 and crucible body with the mixed gas of nitrogen or inert gas
Hole 7 enters in crucible；
It takes the next step, be drained into metallic solution 5 through the gas vent on gas distributor disk 9 into the mixed gas of metallic solution 5
Middle to form multiple bubbles, gas is decomposed into carbon atom in bubble surface, and carbon atom is re-assemblied in bubble surface as graphene, and
Molten surface is reached with bubble afterwards and is flocked together；Gas in the gas source be hydrocarbon gas and inert gas or hydrogen or
The mixed gas obtained after any one gas mixing in nitrogen；Hydrocarbon gas accounts for mixed gas gross weight in the mixed gas
The 2%~5% of amount；The hydrocarbon gas is methane, acetylene, any one in natural gas；The pressure of the gas source be 0.1~
1mpa。
The purpose that cooling chamber 14 is arranged in the present invention is methane, acetylene or other in order to avoid entering in gas distributor disk 9
After mixed gas enters gas distributor disk 9, since the temperature height in gas distributor disk 9 leads to methane, acetylene or other mixing
Type gas Direct Pyrolysis in gas distributor disk 9 generates graphene, and the graphene generated in gas distributor disk 9 deposits to centainly
Latter degree is to block gas vent, and gas distributor disk 9 is also resulted in when serious and is scrapped, and causes unnecessary loss etc..
