Description

Technical Field

[0001] The utility model relates to the technical field of clean workshop ventilation, in particular to a ventilation system for a clean workshop. Background Art

[0002] Cleanroom, also known as clean room, dust-free workshop, clean room or clean room. The main function of cleanroom is indoor pollution control. Without cleanroom, pollution-sensitive parts cannot be mass-produced. Cleanroom is mainly used in instrumentation, precision machinery, aviation, printing and packaging, aerospace and battery production.

[0003] The existing patent with publication number CN116105359A proposes an intelligently controlled clean room ventilation system. The ventilation system is set up to filter through a primary filter, a medium efficiency filter and a high efficiency filter in sequence. The filtered air enters the outlet duct and is discharged through the outlet arranged on the right side of the outlet duct. It is convenient to filter the incoming air and to ensure a dust-free environment in the clean room. Although the ventilation system is provided with a filter to filter impurities in the air, it does not have the function of quickly disassembling and replacing the filter. The filter is used for a long time inside the ventilation duct, and a large amount of pollutants and impurities are attached to the surface. If it is not replaced in time, it is easy to cause the filtered air to carry impurities into the clean room, affecting the safe use of the clean room. In view of the above problems, we propose a ventilation system for clean rooms for transformation and upgrading. Utility Model Content
