Abstract: PURPOSE:To efficiently purify gases by subjecting a dust-containing gas to gas-liquid contact in a packed layer and passing the same through a gas-liquid separator consisting of a rotating drum and a guide plate. CONSTITUTION:A dust-containing gas flowing in through a inlet 10 comes into contact with liquid droplets from a nozzle 14 in a packed material layer chamber 19, with the larger particles thereof flowing downwardly in a liquid reservoir tank.

When a system interconnection voltage Ve exceeds a first set value to be set by a reference-voltage generator (Bv) 4, the MC 6 stops the control of the maximum-power follow-up of the solar cell 2, and a VCVs is fixed to a value at this time. In addition, when the system interconnection voltage exceeds a second set value V2 (>=V1) to be set by a BV 5, a correction voltage is added to the VCVs.  The correction voltage is increased when (Ve-V2)>0, it is decreased when (Ve-V2)<0, and it is fixed when (Ve-V2)=0 so as to be limited in such a way that the correction voltage does not become negative.
