Detailed analysis of the deoxidation principle and composition of the tower deoxidation equipment

Deoxidation principle of tower deoxidation equipment:
 
Due to the large specific surface area of the specially designed tower, the water forms a form of water film which is in contact with the CO2 gas, which not only greatly increases the contact area, but also maximizes the solubility of CO2 in water. The process of deoxidation is achieved by convection of water and CO2 in the packed bed. The water flows from top to bottom by gravity in the tower, and CO2 flows countercurrently from bottom to top with water by pressure difference. Water forms a water film in the tower. When the water film flows from one filler to the next through the contact point, the water in the inner layer of the water film turns to the surface layer, and the water originally in the surface layer turns into the inner layer, so that The gas diffusion speed in the water is reduced, the oxygen release time is shortened, and the deoxidation efficiency is greatly improved. The residual oxygen content of the cold tower deoxygenated water is less than 0.02 ppm. The residual oxygen content of thermal tower deoxygenated water is less than 0.015p
 
The composition of the tower deoxidation equipment:
 
The high-efficiency filler professionally designed degassing tower ensures good high-efficiency degassing with the lowest carbon dioxide gas consumption. The water temperature is raised to 72 degrees Celsius before entering the degassing tower, which reduces the amount of carbon dioxide required for degassing on the one hand and pasteurization on the other hand, thanks to the efficient three-stage plate heat exchanger up to 95 % of the heat has been reused. Cold deoxidation system uses the atmospheric pressure displacement process to prepare deoxidized water. It consists of mass transfer tower, centrifugal pump, automatic control system and other components. The specially designed mass transfer tower mainly uses Henry's law and Dalton's law of partial pressure and adopts high-tech filler. It has a large specific surface area and greatly improves the efficiency of gas-liquid replacement.
 
Deoxygenation unit in tower deoxygenation system:
 
It is mainly composed of gravity flow distributor, high-efficiency filler, packed tower main body, carbon dioxide addition system and centrifugal pump. The good distribution effect combined with the efficient packed tower design allows the water entering the tower to form a large specific surface area on the surface of the filler instantaneously, and achieve good mass transfer effect with carbon dioxide, and obtain high quality deoxidized water. Instantaneous sterilization at the same time as high temperature deoxidation.
