PURPOSE: Disclosed is a continuous dust collection system for a chemical process. The system is able to collect the powders from the flue gas before a gas scrubber and carry out continuously the collecting work without stopping the regeneration of the filtering system or the repairs of the system. CONSTITUTION: The system is composed of two feeding ducts (22,122), two dust collectors (20,120), a filtering system (50,150), a flow pattern transfer system (60,160), a supporting plate (80,180), a cam mechanism (82,84,86,182,184,186), and a driving system (100,102,200,202). The dust collectors (20,120) are selectively worked by the control of a switch operation of two feeding ducts (22,122) along to the operation of two valves system (60,160) by a compressed air. The respective dust collecting chamber (28, 128) in dust collectors (20,120) contains the filtering system (50,150) to collect the powders introduced from the feeding ducts (22,122) by the driving of a blower (122) and the collected powders are heaped up in the powder box.
