Description

Technical Field

[0001] This utility model belongs to the field of drying tower technology, and in particular relates to a cleanable filter cartridge device for drying towers. Background Technology

[0002] For air separation equipment adsorption drying towers, gas is input from the bottom of the drying tower, and after adsorption, it is output from the exhaust pipe at the top of the tower. The exhaust pipe is located at the end of the tower body and a filter cartridge is installed. However, most existing filter cartridges are installed in a fixed manner. If there is any blockage, it will affect the normal use of the drying tower. Similarly, the filter cartridge is located inside the tower, and even if manholes are provided, it is still not conducive to cleaning and maintenance. Moreover, maintenance and cleaning require shutdown and cannot work, thus affecting work efficiency. Summary of the Invention
