PURPOSE: To utilize a deodorizing liquid effectively by separating clean deodorizing liquid by a separating means from a deodorizing liquid recovered in a recovering section for the deodorizing liquid, conducting the clean deodorizing liquid to an atomizing device, thus constituting a recirculation system of deodorizing liquid.
CONSTITUTION: A deodorizing liquid supplied from a deodorizing liquid tank 5 contg. the deodorizing liquid 4, is atomized by an atomizing device 7. Then, the atomized deodorizing liquid 4 is mixed with indoor contaminated air in a deodorizing section 11 to deodorize thus the indoor contaminated air. The deodorized clean air is discharged by a fan 3 to the inside of a room. In the deodorizing liquid recovering section 16, the deodorizing liquid fed to the deodorizing section 11 is recovered, and the clean deodorizing liquid is separated from the recovered deodorizing liquid recovered in the deodorizing liquid recovering section 16 by a separating means 19. The clean deodorizing liquid separated by the separating means 19 is guided to an atomizing means 7 through a pipe 21. As the result, effective utilization of deodorizing liquid is attained.
