Description

Technical Field

[0001] This application relates to the field of shipbuilding technology, and in particular to a sewage discharge pipeline system for container ships. Background Technology

[0002] To ensure safe cargo loading and unloading and to meet the basic living needs of crew members, container ships typically discharge sewage to the outer sides of the ship during operation. This sewage includes grey water and black water. Grey water refers to the wastewater discharged from washbasins, bathtubs, and floor drains in the galley and crew cabins; black water refers to the wastewater discharged from toilets, urinals, toilet floor drains, pharmacies, and wards. Existing sewage discharge pipelines often have many bends, increasing the risk of blockages and pipeline costs. Furthermore, these pipelines must pass through ballast tanks, with some sections constantly submerged in the ballast tank liquid, which easily corrodes pipes and fittings, increasing the difficulty of watertightness and hindering future maintenance. Additionally, in extreme rolling situations, the sewage discharged to the sides of the ship will float on the surface, entering the working range of rescue boats and gangways, thus prolonging rescue time. Utility Model Content

[0003] In view of the deficiencies in the existing technology, this application provides a container sewage discharge pipeline system to solve the technical problems of the existing container sewage discharge pipes outside the ship, such as high risk of pipe blockage, high pipeline layout cost, easy corrosion of pipes and fittings by liquids in the ballast tank, and hindrance to lifeboat rescue.

[0004] To achieve the objectives of the above application, the technical solution provided in this application is as follows:

[0005] A containerized sewage discharge pipeline system includes a sewage pipe that passes sequentially through the top and bottom plates of the cargo hold. The outlet end of the sewage pipe is located in a pipe tunnel area between ballast tanks. The outlet end of the sewage pipe is connected to the inlet end of a sidewall short pipe, the outlet end of which is located in the middle area of ​​the bottom of the ship.

[0006] In one embodiment, watertight penetration components are provided between the sewage pipe and the middle of the ship's bottom surface, and between the sewage pipe and the cargo hold floor.

[0007] In one embodiment, the sewage pipe includes a black water pipe and a grey water pipe.

[0008] In one implementation, side valves are installed between the black water pipe and the side short pipe, and between the grey water pipe and the side short pipe.

[0009] In one embodiment, both the black water pipe and the grey water pipe are equipped with anti-surge valves.

[0010] In one embodiment, the anti-surge valve is located inside the cargo hold.

[0011] In one embodiment, both the black water pipe and the grey water pipe are corrosion-resistant stainless steel pipes or galvanized steel pipes.

[0012] In one embodiment, both the black water pipe and the grey water pipe are provided with a rinsing port.

[0013] In one embodiment, the flushing port is located above the cargo hold.

[0014] In one embodiment, the sewage pipe is perpendicular to the bottom of the ship and is located in the middle area of ​​the bottom of the ship.

[0015] Compared with the prior art, this application has at least the following beneficial effects:

[0016] The sewage discharge pipeline system in this application is installed only in dry cargo holds and pipe tunnel areas, which avoids the accelerated corrosion of sewage pipes in humid environments. Furthermore, the installation of pipes and fittings inside the cargo hold facilitates the maintenance, inspection, and cleaning of the pipeline system.

[0017] The sewage discharge end in this application is located in the middle area of ​​the bottom of the ship. When the ship rolls extremely, the sewage is still discharged downwards, which avoids domestic sewage floating on the water surface on the side of the ship and affecting the launching of rescue boats when the ship tilts, thus eliminating potential risks.

[0018] The sewage pipes in this application are perpendicular to the bottom of the ship, which reduces the length of the side pipes, reduces the difficulty of the side pipe tightness test on the ship, saves side pipe materials, reduces the operation of butt welding on the ship, makes it easier to ensure the quality of the pipes, reduces the workload of operators, and reduces the cost of container sewage discharge.

Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0027] To better understand the technical solution of this application, the application will be described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-3 The present embodiment provides a container sewage discharge pipeline system, including a sewage pipe 1, which passes through the top and bottom plates of the cargo hold 6 in sequence. The outlet end of the sewage pipe 1 is located in the pipe tunnel area 7, which is located between the ballast tanks 8. The outlet end of the sewage pipe 1 is connected to the inlet end of the side short pipe 10, which is located in the middle area of ​​the bottom of the ship.

[0029] Watertight penetration fittings 3 are installed between the sewage pipe 1 and the mid-section of the ship's bottom surface, and between the sewage pipe 1 and the cargo hold floor, to increase the watertightness of the hull. The sewage pipe 1 includes a black water pipe 101 and a grey water pipe 102. In order to control the discharge of sewage, side valves 9 are installed between the black water pipe 101 and the side short pipe 10, and between the grey water pipe 102 and the side short pipe 10.

[0030] To prevent backflow of liquid in sewage pipe 1 and damage to pumps, compressors, and other equipment inside the ship, anti-surge valves 4 are installed on both black water pipe 101 and grey water pipe 102. In this embodiment, the anti-surge valves 4 are located inside the cargo hold. Both black water pipe 101 and grey water pipe 102 in this application are corrosion-resistant stainless steel pipes or galvanized steel pipes.

[0031] Both the black water pipe 101 and the grey water pipe 102 are equipped with flushing ports 5, which are located above the cargo hold 6 to facilitate cleaning, inspection, and maintenance of the pipes by personnel, thereby extending the service life of the sewage pipes and ensuring the normal operation of the pipeline system. In order to reduce the number of pipe bends, reduce the risk of pipe blockage, and reduce pipeline layout costs, in this embodiment, the sewage pipe 1 is perpendicular to the bottom surface of the ship and is located in the middle area of ​​the bottom surface of the ship.

[0032] During normal ship operation, black and grey water discharged from the superstructure, when it is necessary to discharge sewage overboard, is treated by the containerized sewage discharge pipeline system described in this application, which vertically discharges the treated sewage from the middle of the ship's bottom through the cargo hold and pipework area to the overboard. For example... Figure 3 As shown, when the ship experiences extreme rolling, the sewage is still discharged downwards, preventing domestic sewage from floating on the surface, making it easier for rescue boats and gangway access to operate, and shortening rescue time.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation methods of the application or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of this application, and all of them should be covered within the scope of the technical solutions claimed in this application.
