Deep cold air separation method

Generally, the main reason for the vibration of piston type oxygen compressor is the action of alternating load. There are two kinds of alternating loads: one is the unbalanced inertia force, the other is the interference force caused by the strong gas pressure pulse in the gas pipeline caused by the discontinuous gas supply of the compressor. The vibration caused by unbalanced inertia force can be eliminated and reduced from the structure of the machine itself. The specific methods are as follows: reasonably arrange the crank stagger angle; properly select the mass configuration of reciprocating parts. In addition, the basic design and manufacturing process of the compressor should also strictly comply with the technical specifications. For the vibration caused by air flow pressure pulse, a buffer can be installed near the cylinder exhaust pipe nozzle; the appropriate installation position of orifice plate should be selected on the gas flow channel; the shock absorber should be

The nitrogen from the top of the upper tower is piped through the nitrogen gas pipeline, reheated through the main heat exchanger of the colder tower, and a portion of the nitrogen is pumped out, then combined with the first pipeline and a portion of the nitrogen vaporised in the liquefier in the third pipeline before going to the main vessel. The first raw material air pipeline is heated up and out of the cold box in liquid air separation plant, then goes to the high pressure heat exchanger of ...
