Technical Process
1, Picture of technical process
2, Process characteristics:
( 1 ) Using sealed box to feed raw material by vibration. so the safety during feeding process can be assured.
( 2 ) Adopting sulphuric acid liquid purifying technique which is very effectire and safe.
( 3 ) Drying acetylene under high pressure by automatic molecular siere with high automatic level and satisfying dry effect.
( 4 ) Setting up a complete automatic control system to provide necessary supervision and control for the whole production process ro realize automatic feeding. Under abnormal conditions, such as overpressure, overtemperature or no water, the system can give out warning sign and shut off the running of of relative equipment. So that the safety operation of the wholl system can be assured.
( 5 ) Setting up an emergency shut off systm. When sudden dange appears, pressing an emergency button in main workshops can shut off the control power and rlatire equipment to avoid expanding an accident.
