For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figures 1 to 3As shown, the high-efficiency boiler reverse osmosis device of this embodiment includes a raw water tank 1, which is used to store unfiltered water. One end of the raw water tank 1 is connected to a water pump 3 through a water delivery pipe 13, and the water inside the raw water tank 1 can be pumped out through the water pump 3. The other end of the water pump 3 is connected to a quartz sand filter 4 through the water delivery pipe 13. The quartz sand filter 4 uses quartz sand as a filter medium. Under a certain pressure, water with high turbidity is filtered through granular or non-granular quartz sand of a certain thickness, effectively intercepting and removing suspended matter, organic matter, colloidal particles, microorganisms, chlorine, odor and some heavy metal ions in the water. The other end of the quartz sand filter 4 is connected to an activated carbon filter 5 through the water delivery pipe 13. The activated carbon filter 5 can absorb the residual chlorine that cannot be removed in the previous stage filtration, which can effectively ensure the service life of the subsequent equipment, improve the water quality of the effluent, and prevent pollution. The activated carbon filter 5 The other end of the high-pressure pump 8 is connected to a high-pressure pump 8 through a water delivery pipe 13, and the other end of the high-pressure pump 8 is connected to a reverse osmosis membrane assembly 9 through a water delivery pipe 13. Generally, water flows from low concentration to high concentration. The water inside the water delivery pipe 13 is pressurized by the high-pressure pump 8, so that water can enter the inside of the reverse osmosis membrane assembly 9, and water molecules and some mineral ions can pass through. Other impurities and heavy metals will be discharged through the waste water pipe. The reverse osmosis membrane is a prior art, but no further description is given. A cleaning structure is provided on the outside of the reverse osmosis membrane assembly 9. By arranging the cleaning structure on the outside of the reverse osmosis membrane assembly 9, the cleaning structure generally cleans the reverse osmosis membrane assembly 9 regularly by manual means to maintain the performance and life of the membrane. The other end of the reverse osmosis membrane assembly 9 is connected to a pure water tank 11 through a water delivery pipe 13, and the filtered water will enter the pure water tank 11 for storage.

[0023] Specifically, a dosing system 2 is installed on the surface of the water supply pipeline 13, and the dosing system 2 includes a first dosing box 201 and a second dosing box 202. The first dosing box 201 is installed between the raw water tank 1 and the water pump 3, and the second dosing box 202 is installed between the activated carbon filter 5 and the high-pressure pump 8. Biological sterilizers, sodium hypochlorite and other water treatment agents can be added multiple times through the first dosing box 201 and the second dosing box 202 to remove impurities in the water.

[0024] Furthermore, a second control valve 12 is installed on the surface of the water pipe 13 between the raw water tank 1 and the first dosing box 201, and a first control valve 6 is installed on the surface of the water pipe 13 between the high-pressure pump 8 and the second dosing box 202. The second control valve 12 can control the opening and closing of the raw water tank 1, and the first control valve 6 can control the opening and closing of the water pipe 13 between the high-pressure pump 8 and the second dosing box 202. After the filtration is completed, the staff needs to check whether the first control valve 6 and the second control valve 12 are closed in turn.

[0025] Furthermore, a safety filter box 7 is installed on the surface of the water pipe 13 between the second dosing box 202 and the first control valve 6. A plurality of filter nets are arranged inside the safety filter box 7. Some impurities in the water can be removed through the filter nets inside the safety filter box 7.

[0026] Furthermore, a disinfection tank 10 is arranged between the reverse osmosis membrane assembly 9 and the pure water tank 11, and a plurality of ultraviolet lamps 14 are installed inside the disinfection tank 10. The water passing through the reverse osmosis membrane assembly 9 will enter the interior of the disinfection tank 10, and will be disinfected and sterilized under the action of the plurality of ultraviolet lamps 14. The sterilized water will enter the interior of the pure water tank 11 for storage.

[0027] Furthermore, the reverse osmosis membrane assembly 9 includes a main reverse osmosis membrane 901, a first three-way pipe 902, a secondary reverse osmosis membrane 903 and a second three-way pipe 904. One end of the main reverse osmosis membrane 901 is connected to the high-pressure pump 8 through a water supply pipe 13, and the other end of the main reverse osmosis membrane 901 is connected to two secondary reverse osmosis membranes 903 through the first three-way pipe 902. The other ends of the two secondary reverse osmosis membranes 903 are commonly connected to the second three-way pipe 904, and the other end of the second three-way pipe 904 is connected to the disinfection tank 10 through the water supply pipe 13. The water inside the water supply pipe 13 first enters the main reverse osmosis membrane 901 for filtration, and the filtered water will enter the two secondary reverse osmosis membranes 903 for filtration. By setting two secondary reverse osmosis membranes 903, when one secondary reverse osmosis membrane 903 is damaged, the other secondary reverse osmosis membrane 903 can be normal, and then when the user replaces or repairs the secondary reverse osmosis membrane 903, it will not affect the normal use of the reverse osmosis membrane assembly 9.

[0028] Furthermore, the first control valve 6, the second control valve 12, the water pump 3 and the high-pressure pump 8 are all connected to an external control platform, through which the operation of the entire device can be controlled, including the monitoring and adjustment of parameters such as water inlet flow, pressure, and temperature.

[0029] The method of using this embodiment is: open the first control valve 6 and the second control valve 12 in sequence, pump out the water in the raw water tank 1 through the water pump 3, add the agent for removing impurities into the first dosing box 201, and flow into the quartz sand filter 4 and the activated carbon filter 5 for primary filtration, and the filtered water enters the installation filter box for secondary filtration under the transportation of the water pipeline 13, and the secondary filtered water will enter the second dosing box 202, and finally, under the action of the high-pressure pump 8, the water in the water pipeline 13 is sent to the inside of the reverse osmosis membrane assembly 9 for tertiary filtration, and the impurities and minerals in the water are effectively removed by the reverse osmosis membrane assembly 9, and the filtered water enters the disinfection tank 10 for disinfection and disinfection, and obtains high-quality boiler water, and finally enters the pure water tank 11 through the water pipeline 13.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
