The bipolar charged turbulence agglomeration device

which can control PM2.5emission from coal-fired power plants effectively

is a hotspot technology at home and aboard.On the platform of commercial CFD software

drag force and lift force on the agglomeration device turbulence column was calculated by simulating the turbulence field with LES model.The results show that:the force accepted by turbulence column is obviously periodical

of which the drag force is larger than the lift force;the force fluctuation range of the first row is significantly smaller than that of the second row;connecting the four turbulence columns in each row with steel channel and fixing them as a unit

then it can be calculated that the maximum design radial force load of the unit is 8.6times as large as the maximum radial force the first row bearing

and 9.1times as that of the second row bearing.
