Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment on board ships, in particular to a fixed type spraying device for sewage on board ships. Background Art

[0002] The sewage generated on board includes domestic sewage, gray water and oily sewage. When treating sewage, physical and chemical process technologies such as activated sludge method and delayed aeration method are generally used. However, it is generally necessary to spray chemicals in the sewage pool before treatment for pretreatment to improve the efficiency of sewage disinfection.

[0003] However, the current fixed sewage spraying devices on ships are mostly composed of spraying pipes. During the operation, the agent flows through the spraying pipe and is sprayed into the sewage. After the spraying of the agent is completed, some agent will still remain inside the spraying pipe, causing the agent to continue to flow out from the inside of the spraying pipe, resulting in a waste of agent. At the same time, when not in use, the spraying pipe is exposed to the environment and is easily covered by dust, which may cause the nozzle on the spraying pipe to be blocked, affecting the subsequent use of personnel.
