摘要
通过对复合式滤尘器第二级流场的测定,运用流体理论验证了复合式滤尘器(LTG型)第二级的流场是发散型的,且重力场对滤质影响可忽略.这为快捷的气体采样法测定复合式滤尘器的过滤效率提供了依据.
According to the determination of the fluid field of the second stage in composed filter (modle LTG) and verification through fluid theory, it is confirmed that the fluid field of the second stage is spread out in all directions and the effection of the gravity field to the particles can be omitted.It provides the basis for the fast determination of the filter efficiency to the composed filter in the air sampling method.
