DUST REMOVAL SYSTEM

PROBLEM TO BE SOLVED: To provide a dust removal system which can easily eliminate loosening caused by tensile strength acting on link chains.SOLUTION: A dust removal system 10 comprises: paired link chains 22 for supporting a screen 24 arranged in a direction in which the screen traverses a water conduit; go-around means for making the link chains 22 go around; moving means 40 which can move a relative position of a rotation axis of the go-round means; pressing force sensors 50 which press guides from a direction intersecting with a go-around direction of the link chains 22, support the link chains, and measure pressing forces of the link chains by the guides, respectively; and control means 60 which electrically connects the moving means 40 and the pressing force sensors 50, moves the rotation axis by the moving means 40, and can adjust loosening caused by tensile strength of the link chains 22.
