本文较详细地讨论了沉降室的计算。从讨论沉降室外形尺寸开始,进而用微积分方法求出Re<1及Re≤6的尘粒沉降速度方程。尘粒沉至沉降室底所需的时间,分为尘粒达到99%极限速度以前所需的时间及达到99%极限速度后至沉降室底所需的时间两部分,并考虑了满足计算条件的最大允许尘粒粒径。计算方法较以往的要科学些,也较简单。
This article discusses the calculation of the settling chamber in more detail. From the discussion of the external dimensions of sedimentation, the equation for the settling velocity of dust particles with Re<1 and Re≤6 was obtained by using the calculus method. The time required for the dust particles to sink to the bottom of the sedimentation chamber is divided into two parts: the time required before the dust reaches 99% of the speed limit, and the time required to reach the bottom of the chamber after the 99% limit speed is reached, and the conditions for the calculation are considered. The maximum allowable dust particle size. The calculation method is more scientific than the previous one, and it is also relatively simple.
