The pipe array mixer,cross-shaped vane and clapboard flocculation reactor and V-type inclined plate settler were designed according to the micro-vortex control theory,the backward facing step flow theory and the contact flocculation theory respectively.

For the static tubular mixer with tube-arrays,semi-uniform and isotropy turbulent flow takes place using the effect of boundary layer in the arrayed tube,which can achieve rapid mixing.

The text narrated the characteristic,working principle,structure and parameter of PS—600 coal pretreatment processor,which is made of floatation emulsification machine with the type of water belch and pipeline mixed machine.
