Aeration pipes and aeration systems

Abstract

The invention relates to an aeration tube. An aeration tube comprises a main tube and a water outlet tube, wherein the main tube has a main water outlet, an initial mixing section, a main water inlet, and an air inlet; and the water outlet tube is coupled to one end of the main tube which has a main water outlet, and the water outlet tube has a water outlet and a water inlet. The invention also relates to an aeration system. The aeration tube and the aeration system under the invention continually increase the water flow velocity and continually decrease the water pressure by design of a multi-section mixing section and a mixing acceleration section, so that a large amount of air is mixed with the water, thereby increasing the oxygen concentration in the water when the air is subsequently released.
