Due to deformation, the pipeline of the liquid-air steam of the crude argon tower back to the safety valve of the upper tower needs to be re-piped.Fine argon tower condenser liquid nitrogen discharge pipe, add fixed frame below the condenser, add guide frame in the middle of the fine argon tower. In close proximity to the crude argon tower inlet liquid argon pump outlet to the crude argon tower pipeline to a fixed frame, liquid argon pump outlet pipe from the bottom to the first straight section of the top elbow down about 1.5 m position to increase the fixed frame fixed on the cold box plate.
Due to deformation, the safety valve tube on the nitrogen out of the fine argon tower condenser line needs to be replaced and the bracket installed on the cold box.The disconnected fine argon tower evaporator non-condensable gas blow-off tube is restored, the fixed bracket is installed on the evaporator. Replacement of liquid argon metering tank to the fine argon tower deformation serious argon gas pipeline, fixed frame installed on the evaporator. Fine argon tower evaporator liquid nitrogen export line due to deformation need to re-piping, bracket and fixed frame installed in the evaporator body.Lower tower pressure nitrogen to fine argon tower evaporator pipeline, in the nitrogen inlet valve, the valve before the fixed frame, lower tower pressure nitrogen out of the lower tower pipeline to restore.
The automated production line with intelligent MES bus control system enables DEAR intelligent production line to achieve automatic order scheduling and automatic equipment optimisation for production. The intelligent production line not only reduces manpower work by 90%, but also allows lean management of the intelligent system, greatly reducing material costs and doubling production capacity of small air separation units, large air separation units and liquid air separation plants
