A device for removing scale from a duct pipe of a desulfurization system is provided to prevent damage of the duct pipe, reduce costs for maintenance and management, and reduce working hour, thereby increase the working efficiency by completely removing scale formed on an inner side of the duct pipe. A device(100) for removing scale from a duct pipe of a desulfurization system comprises: a suction part(10) including a first screw(11) connected to a steel pipe, a second screw(13) joined with the first screw through a joint(12), and a suction hole(14) penetrated into the first and second screws; a connecting part(20) including a first body(22) in which a third screw(21) is formed to be joined with the second screw, a second body(24) which is connected to the first body, and has a fourth screw(23) formed on an outer side thereof, a third body(26) which is connected to the second body, and in which a first discharge port(25) is formed, a fifth screw(27) connected to the third body, and a flow hole(28) formed in the first to third bodies; a rotary spray part(30) including a fourth body(35) having first to third inflow holes(31-33) formed therein such that the third body is inserted into the first to third inflow holes, and second discharge ports(34) arranged in a predetermined distance on a side face thereof, and discharge bolts(37) which are fitted into the second discharge ports, and in which an injection port(36) is formed; an adjusting part(40) including a first joining groove(41) into which the second body is inserted, first bolt grooves(42), a first bolt(43) fitted into the first bolt grooves, and a nut(44) joined with the fourth screw; and a finishing part(50) including a fifth body(53) in which a sixth screw(51) and a hooking groove(52) are formed, a second joining groove(54) and second bolt grooves(55) formed to be joined with the fifth body, and a second bolt(56) fitted into the second bolt grooves. Further, a size(d1) of the suction hole of the suction part is same with a size(d2) of the flow hole of the connecting part.
