Liquid aeration device - using double-suction impeller on vertical shaft with specified leading parameters

摘要

An aeration device for the introduction of air into water, sewage, sewage sludge or liquid manure carries on a vertical drive shaft a double-suction impeller. The upper blades receives air through a tube around the drive shaft; the lower blades throw the fluid radially outward. The axial height of the gas transport blades at the peripher is made much smaller than that of the fluid transport blades. This results in a much higher efficiency by contacting the air in very fine bubbles with the fluid.
