Description
Technical Field
The utility model relates to an air exhaust packing device, and relates to the field of centrifugal blowers.
Background
The construction of a garbage power plant is an effective way for scientifically and reasonably treating and utilizing garbage, but the garbage power plant has a great problem, namely odor pollution. In the process design, an air intake port of a primary air fan is generally positioned above a garbage bin, and the components of the air intake port contain foul odor positions such as methane, hydrogen sulfide, methyl sulfide and the like. The conventional labyrinth seal has a gap with the main shaft, and the air pressure in the fan is higher than the external atmospheric pressure, so that part of odor is inevitably overflowed, the environment is seriously polluted, and the physical and psychological health of a human body is greatly influenced.
