Description

Technical Field

[0001] This utility model relates to the field of marine dual-fuel main engine test systems, specifically to a methanol supply system water purging supply skid for WinGD dual-fuel main engine testing. Background Technology

[0002] During fuel switching, shutdown, and maintenance of marine methanol dual-fuel main engines, the methanol inside the main engine and related pipelines needs to be purged to a methanol waste collection device to ensure that there are no hazardous or toxic media in the main engine and related pipelines. The WinGD methanol dual-fuel main engine water purging system uses pure water as the medium, with a conductivity of less than 10 μS / cm. The inlet pressure of the main engine is 13 MPa, and the flow rate is 6 m³ / s. 3 / h. Marine main engine testing is generally a non-continuous production process, with large single-use volumes, high operating pressures, and short durations. Therefore, conventional pure water preparation devices on the market cannot meet these requirements at a low cost. Utility Model Content

[0018] The technical solution of this utility model will be further described below with reference to specific embodiments:

[0019] like Figure 1 As shown, a methanol supply system water purging supply skid for WinGD dual-fuel main engine testing includes a pure water preparation system and a pressurized supply system connected by pipelines. The pure water preparation system includes a pressurization component and a filtration component. The pressurized supply system includes a pure water tank 8 and a high-pressure pure water pump 9. The pressurization component pressurizes the raw water and delivers it to the filtration component. The filtered pure water is stored in the pure water tank 8. The high-pressure pure water pump 9 delivers pure water from the pure water tank 8 in a metered manner.

[0020] The pressurization assembly includes a booster pump 2, a pressure tank 1, and a pressure switch. The booster pump 2 is connected to the inside of the pressure tank 1 through a pipeline, and the pressure switch is installed on the pressure tank 1.

[0021] The filtration assembly includes a mechanical filter 3, an activated carbon filter 4, a resin softening tank 5, a 5μ precision filter 6, and a reverse osmosis water purification device 7, which are connected in sequence through pipes.

[0022] Mechanical filter 3 includes a first stainless steel container, a backwash valve, and quartz sand, with the quartz sand housed within the first stainless steel container. Mechanical filter 3 has a backwashing function. It is mainly used to remove particulate impurities, fibers, suspended solids, and colloids from water. Under normal operating conditions, the effluent SDI ≤ 4 and turbidity ≤ 1 NTU.

[0023] The activated carbon filter 4 includes a second stainless steel container, a backwash valve, and coconut shell activated carbon, which is housed within the second stainless steel container. The activated carbon filter 4 also has a backwash function to further remove residual chlorine, detergent residues, organic matter, odors, discoloration, and carcinogens such as chloroform from the water.

[0024] The resin softening tank 5 uses the principle of ion exchange to remove scale-forming ions such as calcium and magnesium from water. It is usually an integrated device consisting of a controller, a resin tank, and a salt tank.

[0025] The function of the 5μm precision filter 6 is to trap particles larger than 5μm from the raw water to prevent them from entering the reverse osmosis system. These particles, accelerated by the high-pressure pump, may puncture the reverse osmosis membrane module, causing significant salt leakage, and simultaneously scratch the impeller of the high-pressure pump, leading to pump damage.

[0026] The reverse osmosis water purification unit 7 includes solenoid valves, a low-pressure protection switch, a high-pressure pump, a fiberglass membrane housing, a reverse osmosis membrane, a computer-controlled water quality monitor, an electrical control unit, a proportioning valve for concentrated and dilute water, a flushing valve, a flow meter, a pressure gauge, and a stainless steel frame. The solenoid valves, high-pressure pump, fiberglass membrane housing, reverse osmosis membrane, proportioning valve for concentrated and dilute water, and flushing valve are connected via pipelines. The computer-controlled water quality monitor is in contact with the water in the reverse osmosis system. The electrical control unit is electrically connected to the computer-controlled water quality monitor and all valves. The low-pressure protection switch, flow meter, and pressure gauge are mounted on the reverse osmosis water purification unit 7. The stainless steel frame supports the reverse osmosis water purification unit 7.

[0027] The principle of the reverse osmosis water purification system is that, driven by the high-pressure pure water pump 9, water molecules in the raw water undergo reverse osmosis. The reverse osmosis membrane traps organic salts, heavy metals, chemical pollutants, bacteria, viruses, pyrogens, etc. in the concentrated water phase and discharges them with the concentrated water. Water molecules and oxygen molecules then pass through the reverse osmosis membrane to form pure water.

[0028] like Figure 2As shown, the high-pressure pure water pump 9 comprises a centrifugal pump, a filter, valves, instruments, and a control box. The centrifugal pump, filter, and valves are installed on the pipeline. The instruments are used to display the value of the pure water being delivered, and the instruments are electrically connected to the control box. The high-pressure pure water pump 9 delivers pure water from the pure water tank 8 at a specific pressure and flow rate according to the host control requirements.

[0029] This embodiment is merely a further explanation of the present invention and is not intended to limit the present invention. Those skilled in the art can make non-creative modifications to this embodiment as needed after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
