Abstract

The multi-tube parallel free rotary thread demisting device includes a soot pit, a side liquid guide plate, liquid accumulation units, free rotary thread units, a fixing support, a flue gas inlet, motor connecting shafts, motors, a casing, a flue gas outlet, and a base support. A main body of the device includes a plurality of free rotary thread units and a plurality of liquid accumulation units that are mounted in parallel. The motors are mounted on an outer wall of the casing. The free rotary thread units are connected to the motors via the motor connecting shafts respectively. The motor connecting shafts are fixed via the fixing support. The device has low resistance, high efficiency, and high flue gas treatment throughput, and can avoid scaling and jamming.
