Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, specifically a multi-effect distilled water production equipment. Background Technology

[0002] Multi-effect distilled water is a high-purity distilled water produced through a multi-stage evaporation-condensation system. It is widely used in pharmaceuticals, electronics, and chemical industries. Multi-effect distillation machines are used in the production of multi-effect distilled water, and while they are mature products, they still have some shortcomings. First, in areas with high-hardness water sources, the pretreatment is insufficient, failing to effectively remove calcium and magnesium ions and particles from the water, leading to scaling within the distillation units. Second, there is a situation where the residual heat from the final stage of steam is not used for pretreatment, resulting in wasted heat. To address these issues, the inventors have proposed a multi-effect distilled water production equipment to solve these problems. Utility Model Content

[0003] In order to solve the problems of scaling inside the multi-effect distillation unit and waste of residual heat during the production of multi-effect distilled water, the purpose of this utility model is to provide a multi-effect distilled water production equipment.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multi-effect distilled water production equipment, including a multi-effect distilled water machine, a raw material water treatment component is provided on one side of the multi-effect distilled water machine, the raw material water treatment component includes a waste heat exchange cylinder, a horizontal pipe is fixedly connected to the side wall of the waste heat exchange cylinder, a spiral tube is arranged around the side wall of the horizontal pipe, a connecting pipe is fixedly connected to the input end of the spiral tube, a water output pipe is fixedly connected to the output end of the spiral tube, a magnetized scale inhibitor cylinder is provided on one side of the waste heat exchange cylinder, the output end of the water output pipe is fixedly connected to the input end of the magnetized scale inhibitor cylinder, a filter cylinder is provided on one side of the magnetized scale inhibitor cylinder, an end cap is detachably provided at the opening of the filter cylinder, a filter element is provided inside the filter cylinder, a second connecting pipe is fixedly connected to the output end of the filter cylinder, and the end of the second connecting pipe away from the filter cylinder is connected to the first-effect water inlet of the multi-effect distilled water machine.

[0005] Preferably, the multi-effect distillation water machine includes a frame, and a base is provided on the side wall of the waste heat exchange cylinder. The side wall of the base is fixedly connected to the side wall of the frame. The base is used to support and fix the waste heat exchange cylinder and the magnetized scale inhibitor cylinder. The waste heat exchange cylinder has a waste heat exchange chamber inside, and the chamber is filled with a thermally conductive silicone grease layer to fill the microscopic gaps between the waste heat exchange cylinder, the horizontal tube, and the spiral tube, thereby improving the heat conduction effect and heating the raw water flowing through the spiral tube. The horizontal tube is located inside the waste heat exchange cylinder. A steam connecting pipe is fixedly connected to the input end of the horizontal tube, and a discharge pipe is fixedly connected to the output end of the horizontal tube. A third connecting pipe is fixedly connected to the end of the steam connecting pipe facing away from the horizontal tube. The third connecting pipe is connected to the last-effect steam output end of the multi-effect distillation water machine. The high-temperature steam discharged from the last-effect steam output end of the multi-effect distillation water machine can enter the horizontal tube through the third connecting pipe to heat the raw water flowing through the spiral tube, so that the waste heat of the last-effect steam is used for the pretreatment of the raw water and to avoid waste of waste heat.

[0006] Preferably, the ends of the connecting pipe and the water output pipe are located outside the waste heat exchange cylinder. A water supply connector is fixedly connected to the end of the connecting pipe, which is used to connect to an external raw water supply pipe. The raw water can enter the spiral tube through the connecting pipe. A first connecting pipe is fixedly connected to the output end of the magnetized scale inhibitor cylinder. The output end of the first connecting pipe is fixed to the input end of the filter cylinder. A permanent magnet array is installed inside the magnetized scale inhibitor cylinder, with a magnetic field strength ≥1200 Gauss. When water flows through the magnetized scale inhibitor cylinder, the crystalline form of calcium and magnesium ions in the water can change from calcite to aragonite. To elaborate further, calcite is a regular cubic crystal and easily adheres to the container surface to form hard scale, while aragonite is needle-shaped. The filter cartridge has a unique structure that allows it to be easily flushed away by water flow, reducing scale buildup. After passing through the magnetized scale inhibitor cartridge, the water enters the filter cartridge through the first connecting pipe. The filter cartridge traps suspended solids and crystalline particles, inhibiting scale formation at the source and reducing maintenance costs. This makes it suitable for areas with high-hardness water sources. The filter cartridge can be made of vertically stacked PP cotton, activated carbon, or ceramic membranes. The upper part of the inner wall of the filter cartridge has an internal thread, and the side wall of the end cap has an external thread. The external thread corresponds to and is threadedly connected to the internal thread. A handle is fixedly connected to the top surface of the end cap. By turning the handle and engaging the external and internal threads, the end cap can be disassembled and reassembled for periodic replacement of the filter cartridge inside the filter cartridge.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: the residual heat of the last-effect steam of the multi-effect distillation water machine can be utilized to heat the raw water in the process, thereby saving the energy consumption of raw water treatment. Moreover, through magnetization treatment, calcium and magnesium ions in the water can be converted into loose crystals, and with the filter element, suspended solids and crystal particles can be intercepted, so as to inhibit the scaling of the machine from the source and reduce maintenance costs.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example: Figure 1-3As shown, this utility model provides a multi-effect distilled water production equipment, including a multi-effect distilled water machine 1. A raw water treatment component 3 is provided on one side of the multi-effect distilled water machine 1. The raw water treatment component 3 includes a waste heat exchange cylinder 5. A horizontal pipe 6 is inserted and fixedly connected to the side wall of the waste heat exchange cylinder 5. A spiral pipe 9 is arranged around the side wall of the horizontal pipe 6. A connecting pipe 10 is fixedly connected to the input end of the spiral pipe 9. A water output pipe 12 is fixedly connected to the output end of the spiral pipe 9. A magnetized scale inhibitor cylinder 13 is provided on one side of the waste heat exchange cylinder 5. The output end of the water output pipe 12 is fixedly connected to the input end of the magnetized scale inhibitor cylinder 13. A filter cylinder 15 is provided on one side of the magnetized scale inhibitor cylinder 13. An end cap 19 is detachably provided at the opening of the filter cylinder 15. A filter element 17 is provided inside the filter cylinder 15. A second connecting pipe 16 is fixedly connected to the output end of the filter cylinder 15. The end of the second connecting pipe 16 away from the filter cylinder 15 is connected to the first-effect water inlet of the multi-effect distilled water machine 1.

[0015] The multi-effect distillation water machine 1 includes a frame 2, and a base 4 is provided on the side wall of the waste heat exchange cylinder 5. The side wall of the base 4 is fixedly connected to the side wall of the frame 2.

[0016] By adopting the above technical solutions, such as Figure 3 As shown, the base 4 is used to support and fix the waste heat exchange cylinder 5 and the magnetized scale inhibitor cylinder 13. The waste heat exchange cylinder 5 is provided with a waste heat exchange chamber inside, and the chamber is filled with a thermally conductive silicone grease layer to fill the micro gaps between the waste heat exchange cylinder 5 and the horizontal tube 6 and the spiral tube 9, so as to improve the heat conduction effect and heat the raw water flowing through the spiral tube 9.

[0017] The horizontal tube 6 is located inside the waste heat exchange cylinder 5. The input end of the horizontal tube 6 is fixedly connected to the steam connecting pipe 7, and the output end of the horizontal tube 6 is fixedly connected to the discharge pipe 8. The end of the steam connecting pipe 7 facing away from the horizontal tube 6 is fixedly connected to the third connecting pipe 21, which is connected to the last effect steam output end of the multi-effect distillation water machine 1.

[0018] By adopting the above technical solution, the high-temperature steam discharged from the last-effect steam output end of the multi-effect distillation water machine 1 can enter the horizontal tube 6 through the third connecting pipe 21 to heat the raw water flowing through the spiral tube 9, so that the waste heat of the last-effect steam can be used for the pretreatment of the raw water and the waste heat can be avoided.

[0019] The ends of the connecting pipe 10 and the water output pipe 12 are located outside the waste heat exchange cylinder 5, and the port of the connecting pipe 10 is fixedly connected to the water supply connector 11.

[0020] By adopting the above technical solution, the water supply connector 11 is used to connect with the external raw water supply pipe, and the raw water can enter the spiral pipe 9 through the connecting pipe 10.

[0021] The output end of the magnetized scale inhibitor cylinder 13 is fixedly connected to the first connecting pipe 14, and the output end of the first connecting pipe 14 is fixed to the input end of the filter cylinder 15.

[0022] By adopting the above technical solution, the magnetized scale inhibitor cylinder 13 is equipped with a permanent magnet array with a magnetic field strength ≥1200 Gauss. When water flows through the magnetized scale inhibitor cylinder 13, the crystalline form of calcium and magnesium ions in the water can be changed from calcite to aragonite. To elaborate further, calcite is a regular cubic crystal that easily adheres to the surface of the container to form hard scale, while aragonite has a needle-like structure and is more easily washed away by the water flow, thereby reducing the amount of scale deposition. After the water passes through the magnetized scale inhibitor cylinder 13, it can enter the filter cylinder 15 through the first connecting pipe 14. The filter element 17 can intercept suspended solids and crystalline particles to inhibit scale formation from the source and reduce maintenance costs, thus making it suitable for areas with high hardness water sources. The filter element 17 can be vertically stacked PP cotton, activated carbon, or ceramic membrane.

[0023] The upper part of the inner side wall of the filter cartridge 15 is provided with an internal thread 18, and the side wall of the end cap 19 is provided with an external thread. The external thread corresponds to the internal thread 18 and is threadedly connected. The top surface of the end cap 19 is fixedly connected with a handle 20.

[0024] By adopting the above technical solution, by turning the handle 20, the end cover 19 can be disassembled and assembled through the mutual cooperation of the external thread and the internal thread 18, so as to replace the filter element 17 in the filter cartridge 15 regularly.

[0025] Working principle: When in use, the high-temperature steam discharged from the last steam output end of the multi-effect distillation water machine 1 enters the horizontal tube 6 through the third connecting pipe 21. The external raw material water supply pipe is connected to the water supply connector 11, so that the raw material water enters the spiral tube 9 through the connecting pipe 10. A waste heat exchange chamber is set inside the waste heat exchange cylinder 5, and the chamber is filled with a thermally conductive silicone grease layer to fill the micro gaps between the waste heat exchange cylinder 5, the horizontal tube 6, and the spiral tube 9, thereby improving the heat conduction effect. In addition, the spiral tube 9 can extend the flow time of the water to heat the raw material water flowing through the spiral tube 9.

[0026] Next, when the water flows through the water output pipe 12 into the magnetized scale inhibitor cylinder 13, the calcium and magnesium ions in the water can be converted into loose crystals. After passing through the magnetized scale inhibitor cylinder 13, the water can enter the filter cylinder 15 through the first connecting pipe 14. The filter element 17 can intercept suspended solids and crystal particles to inhibit scale formation from the source, reduce maintenance costs, and thus be suitable for areas with high hardness water sources.

[0027] After filtration, the water can enter the first-effect inlet of the multi-effect distillation machine 1 through the second connecting pipe 16 for distillation.

[0028] When the filter element 17 is replaced periodically, the handle 20 is turned, and the end cover 19 can be disassembled and assembled through the interaction of the external thread and the internal thread 18, so that the filter element 17 in the filter cartridge 15 can be replaced periodically.

[0029] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
