Abstract: The present disclosure provides an optical module, including: an upper shell including an upper optical-port part, where a first fixing groove is disposed on top of the upper optical-port part; a lower shell including a lower optical-port part, where the lower optical-port part fits and is connected to the upper optical-port part, and a second fixing groove is disposed on top of the lower optical-port part; and an optical-fiber connector with one side clamped in the first fixing groove and the other side clamped in the second fixing groove; where a first shielding strip is disposed on a junction of the upper optical-port part and the lower optical-port part, and extends in multiple directions. In the optical module provided in the present disclosure, electromagnetic shielding is implemented at an optical port of the optical module in multiple directions, thereby improving an electromagnetic shielding effect of the optical module.

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.
