Description
Technical Field
[0001] The utility model belongs to the technical field of ship facilities, and in particular relates to a ship grey water recycling system. Background Art
[0002] Ship graywater refers to the unconventional wastewater generated and discharged during ship production and operation. It primarily comes from sources such as cooling of power machinery and equipment, air conditioning condensate, deck washing, watchtower cleaning, and sewage pipe cleaning. Domestic sewage, on the other hand, refers to wastewater generated during daily life on board a ship, including washing water and cooking water. Considering that directly pumping seawater for toilet flushing can cause corrosion to pipes and related facilities, shipboard freshwater is also used during flushing tests, significantly increasing water consumption. For construction vessels without freshwater generation capabilities, freshwater provided prior to construction is a valuable resource and must be used conserved. The rational use of shipboard freshwater is particularly crucial in construction scenarios where freshwater refilling is inconvenient. At the same time, energy conservation and emission reduction requirements are placing increasing demands on ships, necessitating the introduction of appropriate facilities to reduce waste and sewage discharge.
[0003] By rationally utilizing the gray water generated by various aspects of a ship for flushing and general cleaning, it will help recycle freshwater resources and reduce overall freshwater consumption. Existing technology lacks a suitable ship gray water recycling system, requiring development and design tailored to specific needs. Utility Model Content

[0018] In order to further understand the content, features and effects of the present invention, the following embodiments are given to illustrate in detail.
[0019] See Figure 1 and Figure 2 The ship gray water recycling system of the present invention includes a rainwater tank 2 and a rainwater filter 4, a ship engine gray water tank 19 and a ship engine gray water filter 10, and a domestic gray water tank 23 and a domestic gray water filter 7, all arranged in parallel. Each tank and its filter are connected by connecting pipes 3. A rainwater pipe 5 and a fresh water pipe 6 are connected to the inlet of the rainwater filter 4, a domestic gray water pipe 8 is connected to the inlet of the domestic gray water filter 7, and a ship engine gray water pipe 11 is connected to the inlet of the ship engine gray water filter 10.
[0020] This gray water recycling system is located in an independent cabin below the ship's deck. The rainwater inlet on the ship's deck is connected to a rainwater pipe 5, the freshwater tank of the ship's equipment is connected to a freshwater pipe 6, the ship's domestic gray water collection pipe is connected to a domestic gray water pipe 8, and the ship's engine gray water collection pipe is connected to an engine gray water pipe 11. Thus, rainwater enters rainwater filter 4 via rainwater pipe 5, which removes large particles of debris from the collected rainwater. Domestic gray water enters domestic gray water filter 7 via domestic gray water pipe 8, which removes large particles of debris from the collected domestic gray water. Engine gray water enters engine gray water filter 10, which removes large particles of debris from the collected engine gray water.
[0021] Ultimately, rainwater enters rainwater tank 2 via connecting pipe 3, while domestic graywater enters domestic graywater tank 23 and marine engine graywater enters marine engine graywater tank 19. Preliminary filtration of rainwater is already relatively clean, so it serves as a water source for adjusting domestic and marine engine graywater. When the amount of domestic and marine engine graywater produced is small, they tend to be more viscous. Using rainwater for adjustment improves their fluidity and reduces the concentration of pollutants within them. Freshwater pipe 6 is used to replenish rainwater tank 2, ensuring a sufficient water level.
[0022] like Figure 1 As shown in the figure, the rainwater tank 2, the ship engine gray water tank 19 and the domestic gray water tank 23 are all rectangular boxes with covers. Air holes are set on the top wall of the box to keep the internal and external air pressures consistent. Some of the exhaust gas generated is discharged through the air holes. Therefore, the ship cabin where the system is located should have good exhaust to avoid the accumulation of exhaust gas.
[0023] A first overflow pipe 15 for communicating with the domestic gray water tank 23 and a second overflow pipe 14 for communicating with the marine engine gray water tank 19 are installed on the top side of the rainwater tank 2. When the rainwater tank 2 is full of water, rainwater (and supplementary fresh water) is transferred to the domestic gray water tank 23 and the marine engine gray water tank 19 in an overflow manner, thereby adjusting the water volume in the tank, improving the fluidity of the gray water and reducing the concentration of pollutants in the gray water.
[0024] In this embodiment, a ship engine case drain outlet 21 is provided at the bottom end of the ship engine gray water tank 19, and a domestic tank drain outlet 24 is provided at the bottom end of the domestic tank 23. Sealing plates are installed on the ship engine case drain outlet 21 and the domestic tank drain outlet 24. After the system has been in operation for a long time, sediment products will form at the bottom of the ship engine case gray water tank 19 and the domestic tank 23. The sealing plates on the ship engine case drain outlet 21 and the domestic tank drain outlet 24 are periodically removed, and the sediment products are discharged from the tank using a scraper or other tool.
[0025] The system also includes a circulation device that establishes a mixing and diverting circulation system for the ship's gray water tank 19 and the domestic gray water tank 23, as well as a chemical tank 25 and a dosing assembly 26 for adding chemical liquid to the two tanks. The circulation device promotes circulation and mixing of the gray water, promoting a thorough mixing reaction between the gray water and the chemical liquid. Furthermore, this mixing and diverting process helps balance the water volume within the ship's gray water tank 19 and the domestic gray water tank 23. The chemical tank 25 and dosing assembly 26 are used to add chemical liquid to the two tanks, promoting the reaction and sedimentation of pollutants in the gray water. The added chemical liquid contains chemical ingredients including, but not limited to, oxidants, flocculants, and degreasing agents.
[0026] In this embodiment, the dosing component 26 includes a dosing pump, the pipeline on the inlet of the dosing pump extends to the bottom of the inner cavity of the medicine liquid tank 25, and the pipeline on the outlet of the dosing pump is simultaneously connected to the top wall of the ship engine gray water tank 19 and the domestic gray water tank 23, and an electromagnetic valve is provided on the pipeline. When the medicine liquid needs to be added, the dosing pump is started and the corresponding electromagnetic valve is opened, and the medicine liquid in the medicine liquid tank 25 is transferred to the ship engine gray water tank 19 and / or the domestic gray water tank 23.
[0027] In this embodiment, the circulation device includes a domestic gray water circulation pump 9 installed at the end of the domestic gray water tank 23, a ship engine gray water circulation pump 13 installed at the end of the ship engine gray water tank 19, a first funnel 18 arranged at the top of the domestic gray water tank 23, and a second funnel 17 arranged at the top of the ship engine gray water tank 19. Filter cotton is provided in the funnel, and the filter cotton is used to continuously filter out small particles of debris and flocculants contained in the gray water.
[0028] It also includes a mixing and diversion component 16, which includes a mixing box 16-1, on both sides of the rear of which input pipes 16-2 are provided, and the outlets of the domestic gray water circulation pump 9 and the ship engine gray water circulation pump 13 are respectively connected to the two input pipes 16-2 through pipelines, and a first output pipe 16-4 located in the first funnel 18 and a second output pipe 16-3 located in the second funnel 17 are provided on both sides of the front of the mixing box 16-1, and solenoid valves are provided on the first output pipe 16-4 and the second output pipe 16-3.
[0029] During operation, the domestic gray water circulation pump 9 pumps out the domestic gray water in the domestic gray water tank 23 and transports it to the mixing and diversion component 16 through the pipeline. The marine engine gray water circulation pump 13 pumps out the marine engine gray water in the marine engine gray water tank 19 and transports it to the mixing and diversion component 16 through the pipeline. Therefore, the domestic gray water and the marine engine gray water are mixed in the mixed flow box 16-1 of the mixing and diversion component 16. Then, by controlling the switches of the solenoid valves on the first output pipe 16-4 and the second output pipe 16-3, the mixed gray water is adjusted to be transferred to the domestic gray water tank 23 and / or the marine engine gray water tank 19. The mixed gray water sprayed from the first output pipe 16-4 and the second output pipe 16-3 enter the first funnel 18 and the second funnel 17 respectively, and enter the box below after being filtered by the filter cotton.
[0030] The aforementioned circulation, mixing and diversion effects achieve two effects: the first effect is that the gray water in the box is disturbed by the circulating flow, which promotes the added liquid medicine to fully react with the gray water and flocculate, and the flocculants contained in the gray water circulating through the filter cotton are continuously filtered and retained, so that the pollutants in the gray water in the box are continuously treated; the second effect is to adjust the amount of water in the two boxes by controlling the solenoid valve of the mixing and diversion component 16. For example, when the amount of domestic gray water produced is much less than the amount of ship engine gray water produced, the solenoid valve on the second output pipe 16-3 can be closed to allow more mixed gray water to enter the domestic gray water tank 23. When the amount of gray water in the two boxes is not much different, the aforementioned solenoid valve is reopened, and then the mixing and diversion component 16 transfers the mixed gray water to the first funnel 18 and the second funnel 17 in a relatively balanced manner.
[0031] In this embodiment, a first heater 20 is installed in the ship engine gray water tank 19, and a second heater 22 is installed in the domestic gray water tank 23. The first heater 20 and the second heater 22 are both electric heaters. Their function is to appropriately heat the ship engine gray water and domestic gray water in the tank under low temperature conditions in winter, thereby enhancing the activity of the agent and enhancing the reaction and flocculation of the pollutants in the gray water.
[0032] It also includes a pressure tank 12. The ship engine gray water tank 19 and the domestic gray water tank 23 are connected to the pressure tank 12 through pipelines and transfer pumps. The recovered and treated gray water is pumped into the pressure tank 12 for storage by a transfer pump. The ship's toilet flushing pipes and general cleaning pipes (such as deck flushing pipes, etc.) are connected to the pressure tank 12 to directly take the water in the pressure tank 12.
[0033] This embodiment also includes a base frame 1, on which the rainwater tank 2 and rainwater filter 4, the engine gray water tank 19 and engine gray water filter 10, the domestic gray water tank 23 and domestic gray water filter 7, as well as the pressure tank 12 and the liquid medicine tank 25 are all mounted. This makes the ship gray water recycling system a skid-mounted device, facilitating its integrated transport and deployment. Solid debris trapped by the rainwater filter 4, the engine gray water filter 10, the domestic gray water filter 7, and the filter cotton in the hopper is regularly cleaned and collected, stored as solid waste, and then centrally processed upon arrival at shore.
