A degassing tower, also known as a degassing tank, High quality CO2 degassing tower aquaculture water degasser，uses the wind power of a blower to remove free CO2 from water. Reduce corrosion of backend devices in the system; Because the CO2 content in water reaches a certain level, it will react with water to produce carbonic acid, which will cause ionized hydrogen ions to corrode various equipment at the back end. The degassing tower can also serve as an aeration device, which has a higher air flow rate compared to pipeline aeration and produces better oxidation effects; Compared to blower aeration, deaeration tower aeration uses low-power centrifugal fans, which greatly save electricity and are therefore more widely used in practice. The structure of a degassing tower is mostly a cylindrical tower structure, consisting of a water distribution device, a packing layer (multi-faceted hollow plastic balls, corrugated plates, etc.), and a blowing device (fan). Water enters the tower from the top and is evenly sprayed onto the surface of the packing material by the water distribution device to form a water film. After coming into contact with the air through the packing layer, it flows into the lower collection tank (middle tank). Air is blown in from the bottom of the tower by a blower and discharged from the top along with carbon dioxide released from the water. Multi sided hollow spheres are selected as fillers, and ceramic and plastic can be chosen according to different water quality. They mainly increase the surface area of water and better blow off carbon dioxide.
