AI Technical Summary
In existing multi-stage cryogenic carbon dioxide liquefaction separation towers, the air filter and the fixed frame cannot be separated, which means that the entire component must be replaced each time, resulting in resource waste and increased costs.
A multi-stage cryogenic carbon dioxide liquefaction separation tower was designed. Through sliding connection and spring structure, the air filter element can be separated from the fixed frame, so that the filter element can be replaced individually. The gas purification and cooling are carried out by components such as air pump, air extraction pipe, air suction hood, heat exchanger and cold box distillation tower.
It enables individual replacement of air filters, saving resources and reducing replacement costs.
