[0018] Specifically, when the reactor is cleaned, the rotating mechanism 2 drives the winding mechanism 3 and the cleaning arm 5 to rotate synchronously through the cylindrical tube 23, the cleaning arm 5 drives the nozzle 6 to rotate, and the cleaning liquid supply mechanism 4 starts to supply cleaning liquid to the nozzle 6. When other areas of the inner wall of the reactor need to be cleaned, the winding mechanism 3 is started to change the angle between the cleaning arm 5 and the vertical direction to change the cleaning range. The winding mechanism 3 changes the angle of the cleaning arm 5 in the following way: the second motor 31 is started to drive the capstan 32 to rotate, and the winding wire 34 fixed on the capstan 32 begins to be wound into the capstan 32.
