含尘空气

饲料厂一般采用集中除尘网路，并以含尘空气先分段净化后集中并网的效果较好。

Feed mills usually adopt a central exhaust system of which it is better to clean the dust laden air in different process sections and then collect the dust in a combined central system .

选择了冲击式水浴除尘器或滤袋除尘器，对玉石雕刻通风系统排出的含尘空气进行了除尘净化，除尘器的总除尘效率，前者可达97.0%，后者可达98.0%；

Impinging scrubber or bag filter dust collector were selected to treat the dust laden air from the local exhaust ventilation system , which gave a total collecting efficiency of 97 % for impinging scrubber and 98 % for bag filter ;

当含尘空气通过过滤器时，滤料的初始阻力随滤尘增加而逐步上升。

When air containing dust passes through the filter , the initial resistance of the filter material rises along with the increase of filter dust .
