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 2 5%～ 40 % ,5μm颗粒的除尘效率为 75%～ 98% ,压力损失范围在 3 0～ 13 0Pa。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。
ObjectiveDuring the spreading of respiratory epidemic,to change all-air central air conditioning system in order to clean dust and steri lize air,and to reduce the second pollution and cut off the way of spreading vir us.MethodsStanding on the dust removing,the wet filler is u sed to be the function part of dust collection and sterilization.ResultsThe wet dust collection with filler can usually r emove 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.ConclusionsThe wet dust collection with filler can clean ,sterilize,humidify and cool the air.It can replace the first dust collection i n the traditional air conditioning,and it is important to stop the virsus spread ing by the system,improve the air quality and save the energy.
