Technical Field

[0001] The utility model relates to the technical field of temperature interference prevention for large units of an air separation device, in particular to a temperature interference prevention module for a large unit of an air separation device. Background Art

[0002] The air separation unit is a set of industrial equipment used to separate the various gas components in the air and produce oxygen, nitrogen, argon and other gases of the air components. The most commonly used air separation method is cryogenic distillation. The cryogenic separation method converts air into liquid through the method of compression cycle deep freezing, and then gradually separates and produces oxygen, nitrogen, argon and other inert gases from the liquid air through cryogenic distillation according to different boiling points. It is widely used in traditional metallurgy, new coal chemical industry, large-scale nitrogen fertilizer, professional gas supply and other fields.

[0003] At present, the large units of air separation devices are protected against interference by using metal containers. The circuits to be protected are wrapped in them to prevent interference from electric or magnetic fields. This shielding technology is very expensive, and poor shielding grounding contact will lead to interference that cannot be eliminated. Shielding grounding cannot eliminate interference 100% for large electromagnetic interference. Utility Model Content
