Description

Technical Field

[0001] The utility model relates to an assembled sound-absorbing, sterilizing and purifying unit, belonging to the technical field of clean rooms. Background Art

[0002] A clean room, also known as a dust-free room, is an enclosed space in which parameters such as air cleanliness, temperature, and humidity are controlled as needed, and is applied to industries such as medical treatment, food workshops, and industries with high requirements for cleanliness. The air flow inside the clean room needs to circulate to achieve the purpose of clean air, thereby improving the air quality, air temperature, and humidity requirements inside the clean room.

[0003] Currently, the main way to handle air circulation inside a clean room is to install a purification unit. The purification unit is used to achieve processes such as "sending fresh air", "returning air", "temperature and humidity", "sterilization and purification", and "filtration" according to the level requirements of the clean room, so as to meet the air standard requirements inside the clean room. Existing clean room purification units are generally installed on the upper roof, and the cleanliness, temperature, and humidity of the clean room are controlled through reasonable layout, thereby improving the air quality inside the clean room and ensuring the cleanliness of the clean room. However, when existing clean rooms are being repaired, due to the installation of the unit on the upper roof and the narrow space on the roof, the construction is extremely inconvenient. For example, in the case of the hundred-class operating room integrated disinfection and purification unit with the publication number CN115451487A, the "fan", "evaporation section", "humidification section", "high-efficiency filtration section", and "ultraviolet mirror disinfection section" of the unit are all installed in a unified box, and the box is hoisted onto the upper roof. Although this structure can meet the usage requirements, in the actual application process, due to the need to regularly replace the high-efficiency filter and clean the dust of the fan, during the maintenance process, personnel need to complete corresponding work on the upper roof, which brings inconvenience to the maintenance personnel. In addition, when the unit is performing disinfection and purification work, it will generate a lot of noise, which will affect the users inside the clean room.

[0004] Therefore, there is an urgent need to propose an improved sound-absorbing, sterilizing and purifying unit to solve the above technical problems. Summary of the Utility Model
