DETAILED DESCRIPTION
[0015] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.
[0016] The embodiment of the present utility model: Figure 1As shown, a reverse osmosis and sodium bed drainage utilization system includes a pure water preparation production line and a softened water preparation production line. The first sodium bed 1 in the pure water preparation production line is connected to the cooling pool 3 through a first pipeline 2, the reverse osmosis filter 4 in the pure water preparation production line is connected to the second raw water tank 6 in the softened water preparation production line through a second pipeline 5, and the second sodium bed 7 in the softened water preparation production line is connected to the cooling pool 3 through a third pipeline 8.
[0017] An electric valve is provided on the first pipeline 2. Opening the electric valve allows the wastewater generated by the first sodium bed 1 to be discharged into the cooling pool 3, thereby cooling the wastewater discharged from the boiler 21. A motorized valve is also provided on the third pipeline 8. Opening the electric valve on the third pipeline 8 allows the wastewater generated by the second sodium bed 7 to be discharged into the cooling pool 3, thereby cooling the wastewater discharged from the boiler 21. This effectively reduces the use of tap water and conserves water resources.
[0018] The second pipeline 5 is provided with a valve and an electric valve. During daily operation, the valve on the second pipeline 5 is normally open. By opening the electric valve, the concentrated water produced by the reverse osmosis filter 4 can be sent to the second raw water tank 6 in the softened water preparation production line. The concentrated water is mixed with tap water in the second raw water tank 6 and then sent to the second sodium bed 7 to produce softened water. The softened water can be used for equipment with lower requirements for soft water standards.
[0019] In a specific embodiment, the pure water preparation production line includes a first raw water tank 9, a first sodium bed 1, a first water tank 10, a reverse osmosis filter 4 and a pure water tank 11. The first raw water tank 9 is connected to the first sodium bed 1 through a fourth pipeline 12, the first sodium bed 1 is connected to the first water tank 10 through a fifth pipeline 13, the first water tank 10 is connected to the reverse osmosis filter 4 through a sixth pipeline 14, and the reverse osmosis filter 4 is connected to the pure water tank 11 through a seventh pipeline 15.
[0020] The first raw water tank 9 is connected to a tap water pipe equipped with an inlet valve. Tap water is supplied to the first raw water tank 9 through the tap water pipe. The fourth pipeline 12 is equipped with a first water pump 28 and an electric valve. The electric valve and first water pump 28 on the fourth pipeline 12 are opened to pump the tap water in the first raw water tank 9 into the first sodium bed 1. Calcium and magnesium ions are adsorbed on the tap water in the first sodium bed 1 to produce softened water. The fifth pipeline 13 is equipped with a valve and an electric valve. Opening the valve and electric valve on the fifth pipeline 13 allows the softened water produced by the first sodium bed 1 to enter the first water tank 10 for storage. Simultaneously, wastewater generated by the first sodium bed 1 is discharged into the cooling pool 3 through the first pipeline 2.
[0021] A second water pump 29 and a valve are provided on the sixth pipeline 14. By opening the second water pump 29 and the valve on the sixth pipeline 14, the softened water stored in the first water tank 10 is pumped into the reverse osmosis filter 4. The softened water is filtered out of other ions in the reverse osmosis filter 4 to produce pure water. A valve is provided on the seventh pipeline 15. When the valve on the seventh pipeline 15 is opened, the pure water produced by the reverse osmosis filter 4 flows through the seventh pipeline 15 into the pure water tank 11 for storage. Simultaneously, the concentrated water produced by the reverse osmosis filter 4 is discharged into the second raw water tank 6 through the second pipeline 5.
[0022] Furthermore, the pure water tank 11 is connected to a total water outlet pipeline 16, which is connected to the eighth pipeline 17, the ninth pipeline 18 and the tenth pipeline 19 through a tee respectively. The eighth pipeline 17 is connected to the first equipment 20, the ninth pipeline 18 is connected to the boiler 21, and the tenth pipeline 19 is connected to the second water tank 22 in the softened water preparation production line.
[0023] The main outlet pipe 16 is equipped with a third water pump 30. The eighth and ninth pipes 17 and 18 are equipped with valves that are normally open. The tenth pipe 19 is equipped with an electric valve that opens on demand. The boiler 21 is connected to the cooling pool 3 via the eleventh pipe 23. The eleventh pipe 23 is equipped with an electric valve, and the high-temperature wastewater generated by the boiler 21 is discharged into the cooling pool 3 through the eleventh pipe 23 for cooling.
[0024] The pure water in the pure water tank 11 is pressurized by the third water pump 30 and then supplied to the first device 20 and the boiler 21. The first device 20 is a prior art device and can be any device in the silk-making equipment that requires pure water.
[0025] Furthermore, the softened water preparation production line includes a second raw water tank 6, a second sodium bed 7 and a second water tank 22. The second raw water tank 6 is connected to the second sodium bed 7 through a twelfth pipeline 24, and the second sodium bed 7 is connected to the second water tank 22 through a thirteenth pipeline 25.
[0026] The second raw water tank 6 is connected to a tap water pipe equipped with an inlet valve. Tap water is supplied to the second raw water tank 6 through the tap water pipe. A fourth water pump 31 and an electric valve are provided on the twelfth pipeline 24. When the electric valve and the fourth water pump 31 on the twelfth pipeline 24 are opened, the tap water in the second raw water tank 6 is pumped into the second sodium bed 7. Calcium and magnesium ions are adsorbed on the tap water in the second sodium bed 7 to produce softened water. A valve and an electric valve are provided on the thirteenth pipeline 25. When the valve and the electric valve on the thirteenth pipeline 25 are opened, the softened water produced in the second sodium bed 7 is allowed to enter the second water tank 22 for storage. Simultaneously, wastewater generated by the second sodium bed 7 is discharged into the cooling pool 3 via the third pipeline 8.
[0027] Furthermore, the second water tank 22 is connected to the second device 27 via a fourteenth pipeline 26 . A fifth water pump 32 and a valve are provided on the fourteenth pipeline 26 , and the softened water in the second water tank 22 is pumped to the second device 27 via the fifth water pump 32 .
[0028] Second device 27 is conventional technology and can be any water softening device in existing silk-making equipment. However, second device 27 has lower requirements for softened water quality. Therefore, the concentrated water produced by reverse osmosis filter 4 can be discharged into second raw water tank 6 via second pipeline 5. It should be noted that in daily production, the softened water produced by the concentrated water produced by reverse osmosis filter 4 after passing through second sodium bed 7 is sufficient for use by second device 27. Only when the concentrated water production is insufficient is it necessary to add tap water to second raw water tank 6.
[0029] Furthermore, the second water tank 22 is connected to the first water tank 10 via a fifteenth pipe 33. The fifteenth pipe 33 is provided with an electric valve.
[0030] If a failure occurs in the first sodium bed 1 or other equipment at the front end of the reverse osmosis filter 4, the soft water in the first water tank 10 may be unqualified or lack water. To avoid unqualified soft water or lack of water in the first water tank 10, the softened water in the second water tank 22 can also enter the first water tank 10 through the fifth water pump 32 and the fifteenth pipeline 33. The soft water in the first water tank 10 then enters the reverse osmosis filter 4 to be made into pure water for use by the first equipment 20 and the boiler 21.
[0031] In another case, if the second sodium bed 7 or the electric valve and other equipment fail, it may cause the soft water in the second water tank 22 to be unqualified or lack of water. To avoid the soft water in the second water tank 22 being unqualified or lack of water, the electric valve on the tenth pipeline 19 is opened, and the pure water in the pure water tank 11 can enter the second water tank 22 through the third water pump 30, the total water outlet pipeline 16, and the tenth pipeline 19, thereby replenishing the second water tank 22 with pure water, making the water in the second water tank 22 qualified, thereby avoiding the equipment from shutting down due to unqualified water quality or lack of water.

The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings.
