We have developed a new type of dust collec- tor-outer rotation cyclone-with an internal perforated cylinder to eliminate internal eddy currents. It can decrease the pressure loss by 40%,while maintaining the same dust collecting efficiency.

• 新近研制的XW型旋风除尘器通过设置开孔的内筒来消除内涡旋,可使除尘器在保证除尘效率不降低的情况下,压力损失减小40%25。
