PURPOSE:To avoid the leak of offensive odor even when charge port and discharge port are opened by connecting an exhaust fan and a deodorizer in series to an enclosed type wastes treament chamber. CONSTITUTION:In a wastes treatment chamber 1 having a charge port 4 on one side of the rear end wall of a storage tank 2 and a discharge port 5 at the central part of the front end wall, an exhaust fan 18 is provided at the ceiling and also connected to a deodorizer 19. The exhaust fan 18 is automatically operated interlockingly with the opening or closing of the doors of the charge port 4 and the discharge port 5 and offensive odor from the wastes is forcibly sent to the deodorizer 19. Thus, even when the doors are opened or closed, leak of offensive odor to the outside can be prevented and workers can therefore be protected from unpleasant environment. |
