PURPOSE: To provide an apparatus for removing moisture in dust collector, the apparatus capable of efficiently collecting dust of raw coal passing through coal moisture control equipment and preventing closing of filter bag apertures and clogging of transfer line generated accordingly. CONSTITUTION: The apparatus for removing moisture in dust collector comprises a three way valve(12) installed such that the three way valve is communicated with the output side of the dust collector(10); an exhaust duct installed such that the exhaust duct is communicated with one side of the three way valve to exhaust collected waste gas; a reversing air duct installed such that the reversing air duct is communicated with the other side of the three way valve to supply reversing air of high temperature for drying the inside of the dust collector; a reversing air supply means for supplying reversing air into the reversing air duct; and a control means for controlling the three way valve, wherein the reversing air supply means comprises a heat exchanger(30), a flow control valve(32), a temperature sensor(34) and a first control panel(36), and wherein the control means comprises differential pressure meters(40a,40b), and a second control panel(42).
