  • 空气净化工程中气压的稳定方法是什么?
    来源: 浏览:次 发布日期:2019-10-14
      空气净化工程porject中的气压如何指定? 对于大多数清洁容量,为了防止外部污染的侵入,有需要保持内部压力(静态压力)高于外部压力(静态压力)。 保持压差一般应符合以下原则:
      How to specify the air pressure in the air purification project? For most clean spaces, in order to prevent the invasion of external pollution, it is necessary to keep the internal pressure (static pressure) higher than the external pressure (static pressure). Maintaining the differential pressure should generally comply with the following principles:
      1.清洁容量中的压力高于非清洁容量中的压力。
      1. The pressure in clean space is higher than that in non-clean space.
      2.清洁度高的容量中的压力高于清洁度低的容量中的压力。
      2. The pressure in high cleanliness space is higher than that in low cleanliness space.
      压力差的维持取决于新鲜空气的量,该新鲜空气的量能够补偿在该压力差下从间隙泄漏的空气量。 易于 ,压差的物理含义是当气流的泄漏(或渗透)穿过洁净室的各个间隙时的阻力。
      The maintenance of the pressure difference depends on the amount of fresh air, which can compensate for the amount of air leaking from the gap under the pressure difference. Therefore, the physical meaning of pressure difference is the resistance of air leakage (or permeation) through the clearances of the clean room.
      洁净室中的气流速度规定
      Air speed regulation in clean rooms
     空气净化工程
      此处聊下的气流速度是指洁净室中的气流速度,在聊下特定设备时将说明其他洁净容量中的气流速度。
      The airflow velocity discussed here refers to the airflow velocity in the clean room. When discussing specific equipment, the airflow velocity in other clean spaces will be explained.
      对于湍流的洁净室,主要原因是通过空气的稀释感化来减少房间内部污染的程度。 易于 ,主要采取应用换气次数的概念代替速度的概念,但房间内部空气的流速也有以下要旨;
      For turbulent clean rooms, the main reason is to reduce the degree of indoor pollution through dilution of air. Therefore, the concept of ventilation frequency is mainly used to replace the concept of speed, but the flow rate of indoor air also has the following requirements.
      1)出风口的风速不要太大。 与easy的空调客厅相比,速度衰减更快,扩散角更大。
      1) The wind speed of the outlet should not be too high. Compared with simple air-conditioned rooms, the speed attenuation is faster and the diffusion angle is larger.
      (2)穿过水平面的气流速度( 诸如,送出侧面时的再循环速度)不应过大,以防止表面颗粒返回气流并遭成再次污染, 一贯不适合干燥。用于平行流洁净室。
      (2) The air velocity passing through the horizontal plane (e.g. the recirculation speed when sending out the side) should not be too high to prevent the surface particles from returning to the air stream and causing re-pollution, which is usually not suitable for drying. Used in parallel flow clean room.
