Description

Technical Field

[0001] The utility model relates to the technical field of ammonia treatment, in particular to a marine ammonia adsorption tank. Background Art

[0002] At present, passenger and cargo ships sailing on inland rivers generally use diesel engines as the driving force of the ships. Since high-power diesel engines will emit a large amount of exhaust gas when working, in order to ensure compliance with environmental protection standards, ammonia will be used to absorb the highly polluting components in the exhaust gas. During the treatment process, ammonia leakage is inevitable. Since the interior of the hull is basically a sealed space, ammonia leakage will pollute the environment inside the ship, and people in the polluted area are prone to discomfort or even poisoning due to inhalation of ammonia. The current treatment method is to use an ammonia absorption tower to absorb ammonia by spraying, but due to limited space in the hull, only small-sized absorption tanks can be set up, and ammonia is less obstructed in the tank body. The absorption time through spraying is short, and ammonia is not fully in contact with soft water. Generally, porous fillers are added inside to increase the surface contact area to solve this problem. Most absorption towers are equipped with a filler layer below the spray head to increase the contact effect between the absorption liquid and the exhaust gas by using the filler layer, thereby improving the absorption effect. The filler needs to be replaced after long-term use, but the ammonia absorption tower currently used is not convenient for replacing the filler;

[0003] The utility model patent with application number CN217988877U discloses an ammonia absorption tower, which includes an absorption tower body, a filling layer is arranged in the absorption tower body, a support ring for supporting the filling layer is fixed on the inner wall of the absorption tower body, a door panel is arranged on the side wall of the absorption tower body, one side of the door panel is hinged to the side wall of the absorption tower body, and the other side of the door panel is provided with a fixing assembly, the door panel is fixed to the side wall of the absorption tower body by the fixing assembly, and has the effect of facilitating the replacement of the filling layer, but the filling replacement opening of the equipment is arranged horizontally. When the horizontal opening is too large, it will seriously affect the strength of the tank body, resulting in the inability to open the opening too large, thereby resulting in a smaller actual area of ​​the filling, affecting the absorption efficiency, and an exothermic reaction will occur when ammonia is absorbed, which will increase the temperature of the ammonia water, resulting in a decrease in solubility, further reducing the absorption efficiency, resulting in poor ammonia absorption effect, and there is room for further improvement.
