Description

Technical Field

[0001] The utility model belongs to the technical field of air filters, and in particular relates to an air filter for air separation equipment. Background Art

[0002] Air separation equipment uses air as raw material, converts air into liquid through compression cycle deep freezing, and then gradually separates oxygen, nitrogen, argon and other inert gases from liquid air through distillation. Air filters refer to air filtering devices, which mainly include five types: coarse efficiency filters, medium efficiency filters, high and medium efficiency filters, sub-high efficiency filters and high efficiency filters. Each type has different standards and performance.

[0003] When filtering air, the gas is often guided by a fan. However, since dust particles are inevitably present in the gas and most filter elements are placed vertically or horizontally, the dust particles may damage the filter element when the fan guides the gas, thereby reducing the service life of the filter element.
