WIND POWER GENERATION SYSTEM USING SURPLUS WIND POWER OF DUST COLLECTOR

PROBLEM TO BE SOLVED: To provide a wind power generation system using surplus wind power of a dust collector for making a wind power generator generate electric power by using the surplus wind power of the dust collector.SOLUTION: The wind power generation system includes: the dust collector 11; a main duct 14 provided in the dust collector 11; branch ducts 24 with branch side dampers 25 interconnecting the main duct 14 and dust collection ports 23 of a processing machine 21; and bypass ducts 32 with bypass side dampers 33, wherein one ends 32a are connected to the main duct 14 and the other end 32b sides have the wind power generator 31. The processing machine 21 includes an opening/closing control means 22 opening the branch side dampers 25 during processing and closing the branch side dampers 25 during non-processing. An output control means 41 connected to a hub 42 forming a network 43 with the control means 22 calculates current necessary air quantity of the dust collector 11 based on the number of branch side dampers 25 in the opened state and opens the bypass side dampers 33 in accordance with a degree of the allowance so as to enable power generation by the wind power generator 31.
