[0018] The technical solution of the present invention is further described below in conjunction with specific implementation methods:

[0019] like Figure 1 As shown, a methanol supply system water purge supply skid for WinGD dual-fuel host testing includes a pure water preparation system and a boost supply system connected by pipelines. The pure water preparation system includes a boost component and a filter component. The boost supply system includes a pure water tank 8 and a high-pressure pure water pump 9. The boost component boosts the raw water and delivers it to the filter component. The filtered pure water is stored in the pure water tank 8, and the pure water in the pure water tank 8 is quantitatively delivered by the high-pressure pure water pump 9.

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

[0021] The filtering 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 production device 7 which are sequentially connected through pipelines.

[0022] The mechanical filter 3 includes a first stainless steel container, a backwash valve and quartz sand, wherein the quartz sand is arranged in the first stainless steel container. The mechanical filter 3 has a backwash function. It is mainly used to remove granular impurities, fibers, suspended matter and colloids in water. Under normal working conditions, the outlet water SDI is ≤4 and the turbidity is ≤1NTU.

[0023] The activated carbon filter 4 includes a second stainless steel container, a backwash valve and coconut shell water purification activated carbon, and the coconut shell water purification activated carbon is arranged in the second stainless steel container. The activated carbon filter 4 also has a backwash function, which is used to further remove residual chlorine, organic matter such as detergent, odor, discoloration and carcinogen chloroform in the water.

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

[0025] The function of the 5μ precision filter 6 is to intercept particles larger than 5μ brought by the raw water to prevent them from entering the reverse osmosis system. After being accelerated by the high-pressure pump, such particles may break through the reverse osmosis membrane assembly, causing a large amount of salt leakage, and at the same time scratch the impeller of the high-pressure pump, causing damage to the high-pressure pump.

[0026] The reverse osmosis water making device 7 includes a solenoid valve, a low-pressure protection switch, a high-pressure pump, a glass fiber reinforced plastic membrane shell, a reverse osmosis membrane, a computer water quality measuring and controlling instrument, an electronic control unit, a concentrated and fresh water proportional valve, a flushing valve, a flow meter, a pressure gauge, and a stainless steel frame. The solenoid valve, the glass fiber reinforced plastic membrane shell of the high-pressure pump, the reverse osmosis membrane, the concentrated and fresh water proportional valve, and the flushing valve are connected through pipelines, the computer water quality measuring and controlling instrument is in contact with the water body in the reverse osmosis water making device, the electronic control unit is electrically connected to the computer water quality measuring and controlling instrument and each valve, the low-pressure protection switch, the flow meter, and the pressure gauge are installed on the reverse osmosis water making device 7, and the stainless steel frame is used to support the reverse osmosis water making device 7.

[0027] The principle of the reverse osmosis water production system is that under the impetus of the high-pressure pure water pump 9, the water molecules in the raw water are reversely osmotic, and the reverse osmosis membrane retains the organic salts, heavy metals, chemical pollutants, bacteria, viruses, heat sources, etc. in the water in the concentrated water phase and discharges them with the concentrated water, while the water molecules and oxygen molecules 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, a valve, an instrument and a control box. The centrifugal pump, the filter and the valve are installed on the pipeline. The instrument is used to display the value of the pure water delivered, and the instrument is electrically connected to the control box. The high-pressure pure water pump 9 delivers the pure water in the pure water tank 8 at a specific pressure flow rate according to the host control requirements.

[0029] This embodiment is only a further explanation of the invention rather than a limitation of the invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as they are within the scope of the claims of the invention, they are protected by the patent law.
