湿式填料在中央空调中除尘的效果观察

Study on effect of wet on dust collection of central air conditioning

摘要

摘要:
目的在呼吸性传染病高发时期, 改造全空气中央空调系统, 实现净化、消毒功能, 减少二次污染, 以切断病毒的传播途径。
方法以除尘为立足点, 利用湿式填料除尘器作为空气粉尘过滤和消毒的功能段。
结果通常情况下, 湿式填料除尘器对1μm粉尘除尘效率可以达到25%~40%, 5μm颗粒的除尘效率为75%~98%, 压力损失范围在30~130Pa。
结论湿式填料除尘器具备净化、消毒、加湿、蒸发冷却等功能, 可以替代传统空调中的初效过滤器, 对阻止传染病利用空调系统蔓延、改善空气品质和节省能源消耗具有重要作用。

Abstract:
Objective During the spreading of respiratory epidemic, to change all-air central air conditioning system in order to clean dust and sterilize air, and to reduce the second pollution and cut off the way of spreading virus.
Methods Standing on the dust removing, the wet filler is used to be the function part of dust collection and sterilization.
Results The wet dust collection with filler can usually remove the 25-40 percent of dust with a diameter of 1 micron, and 75-98 percent of 5 micron, but the pressure loss is 30-130 pascal.

Conclusions The wet dust collection with filler can clean, sterilize, humidify and cool the air.It can replace the first dust collection in the traditional air conditioning, and it is important to stop the virsus spreading by the system, improve the air quality and save the energy.
