Description

[0002] During the operation of thermal systems, it is common for condensate, drain water, and circulating water in the heat network to be discharged due to poor water quality. This discharge results in a waste of heat energy and water resources, so the conventional approach is to treat them through filtration and desalination.

[0045] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] In order to facilitate understanding of the water treatment and purification device and system provided by the utility model, its application background is first introduced. During the operation of the thermal system, condensate, hydrophobic water and heat network circulating water are often discharged due to poor water quality, but this will cause a waste of heat energy and water resources. Therefore, the conventional practice is to treat them by filtering and desalination.

[0047] The pollution sources of condensate, hydrophobic water, and circulating water in the heating network are mainly caused by raw water, system leakage, and system corrosion. The pollution caused by system corrosion generally accounts for more than 80%, and most of the corrosion products are ferromagnetic substances. Therefore, in related technologies, magnetic filters are generally used for the filtration of condensate, hydrophobic water, and circulating water in the heating network.

[0048] However, magnetic filters can only remove ferromagnetic substances in water. Non-magnetic particles in the water will dissolve at high temperatures in the thermal system and precipitate harmful substances, which can easily cause scaling of equipment such as heat exchangers, steam turbines, and turbines, affecting the safe operation of the equipment.

[0049] In response to the above technical problems, the present invention provides a water treatment and purification device and system, which can improve the water quality of the effluent and ensure the safe operation of subsequent equipment.

[0050] The following combination Figures 1-6 The utility model is described in detail regarding a water treatment and purification device and system.

[0051] Reference Figure 1 A water treatment and purification device includes a device body 10, a permanent magnet component 20 and a filter component 30; wherein, a magnetic purification chamber and a precision purification chamber that are connected to each other are provided in the device body 10, and a water inlet 11 and a water outlet 12 are provided on the device body 10, the water inlet 11 is connected to the magnetic purification chamber, and the water outlet 12 is connected to the precision purification chamber; the permanent magnet component 20 is arranged in the magnetic purification chamber, and the filter component 30 includes a filter membrane 300 arranged in the precision purification chamber, and the filter membrane 300 is used to separate the precision purification chamber into an outer chamber 13 and an inner chamber 14, the magnetic purification chamber is connected to the outer chamber 13, and the water outlet 12 is connected to the inner chamber 14.

[0052] In actual operation, water flows through the water inlet 11 and enters the magnetic purification chamber. During the process of water flowing through the magnetic purification chamber, the permanent magnet component 20 located in the magnetic purification chamber can adsorb and purify the ferromagnetic substances in the water. After magnetic purification, the water will flow into the outer cavity 13 of the precision purification chamber. Under the action of water pressure, the water flows through the filter membrane 300 and enters the inner cavity 14 of the precision purification chamber. During the process of water flowing through the filter membrane 300, the filter membrane 300 can filter the non-magnetic particles in the water. The water filtered by the filter membrane 300 flows out from the water outlet 12. Compared with related technologies, the magnetic purification component can adsorb magnetic impurities in the water to remove magnetic impurities in the water, and magnetization can slow down the corrosion and scaling of the thermal system; the filter membrane 300 can filter the water after magnetic purification and remove the non-magnetic particles in the water, thereby improving the water quality and ensuring the safe operation of subsequent equipment; in addition, the permanent magnet component 20 can be reused for a long time, effectively reducing waste generation and being green and environmentally friendly.

[0053] In one embodiment of the present invention, the device body 10 is a cylindrical tube-shaped structure as a whole, the magnetic purification chamber and the precision purification chamber are coaxially arranged along the axial direction of the device body 10, the water inlet 11 is arranged at one end of the device body 10, and the water outlet 12 is arranged at the other end of the device body 10, and the permanent magnet component 20 is arranged along the axial direction of the magnetic purification chamber, so that when water flows from the water inlet 11 to the water outlet 12, the permanent magnet component 20 can fully adsorb magnetic impurities in the water.

[0054] In one embodiment of the present invention, referring to Figure 2 and Figure 3 The permanent magnet assembly 20 includes a plurality of permanent magnet rods 21 arranged at intervals, each of which is arranged axially along the magnetic purification chamber. The specific number and arrangement of the permanent magnet rods 21 can be flexibly configured based on actual needs, such as the size of the magnetic purification chamber, water quality requirements, and the magnetic field influence range of the permanent magnet rods 21. It is sufficient that the magnetic field range of the plurality of permanent magnet rods 21 covers the entire magnetic purification chamber.

[0055] The specific structure of the permanent magnet bar 21 can be designed according to actual needs. In this embodiment, the permanent magnet bar 21 includes a magnet bar sleeve 210, a magnetic block 211 and a pad 212; wherein the magnetic block 211 and the pad 212 are alternately filled in the magnet bar sleeve 210; the magnetic field strength of the magnetic block 211 gradually increases from the water inlet 11 to the water outlet 12, and the pad 212 is made of anti-magnetic material, so that the magnetic field strength of the permanent magnet bar 21 is arranged from weak to strong along the direction of water flow.

[0056] In actual applications, at the water inlet 11, the concentration of magnetic particles in the water is the highest, and the permanent magnet rod 21 can capture the magnetic particles more easily. As the water flows, the concentration of the magnetic particles decreases. By arranging the magnetic field strength of the permanent magnet rod 21 from weak to strong along the direction of water flow, impurities can be evenly adsorbed at various parts of the permanent magnet rod 21, avoiding the problem of blockage or falling off caused by excessive adsorption of local impurities, thereby ensuring the efficiency of magnetic purification.

[0057] Specifically, the magnetic rod sleeve 210 is cylindrical and made of stainless steel with a wall thickness of less than 1 mm, seamless and smooth surface. This configuration helps to reduce the resistance encountered by water flow and improve corrosion resistance.

[0058] Magnetic block 211 can be made of a rare earth permanent magnet material such as neodymium iron boron or samarium cobalt. Rare earth permanent magnets have strong magnetic force, which improves the iron removal efficiency and dirt holding capacity of permanent magnet bar 21. The magnetic field strength of magnetic block 211 is preferably 3000-10000 GS. Spacer 212 is cylindrical and conforms to the shape of magnetic bar sleeve 210 and magnetic block 211.

[0059] It is understandable that, according to different practical needs, the magnetic rod sleeve 210, the magnetic block 211 and the spacer block 212 can also be set to other shapes or materials.

[0060] In one embodiment of the present invention, referring to Figure 4 The filter membrane 300 is a hollow columnar structure. The space enclosed by the filter membrane 300 is the aforementioned inner cavity 14, and the space outside the filter membrane 300 is the aforementioned outer cavity 13. The filter assembly 30 also includes an upper cover plate 301 and a lower cover plate 302. The upper cover plate 301 is used to close the upper opening of the filter membrane 300, and the lower cover plate 302 is used to close the lower opening of the filter membrane 300. The upper cover plate 301 is provided with a water outlet hole 303 that is in communication with the inner cavity 14, and the water outlet hole 303 is in communication with the water outlet 12. With this arrangement, water after magnetic purification enters the outer cavity 13 of the precision filter cavity. Under the action of water pressure, the water passes through the filter membrane 300 into the inner cavity 14 and is discharged through the water outlet hole 303 and the water outlet 12, thereby completing the filtration.

[0061] Depending on actual needs, such as the desired filtration accuracy, the filter membrane 300 can be made of different materials and structures. Specifically, the filter membrane 300 can be arranged as a single-layer structure. When higher filtration accuracy is required, the filter membrane 300 can also be arranged as a multi-layer structure for multi-layer filtration. Materials for the filter membrane 300 include filter cloth, wound filter material, carbon layer, nano-adsorbent material, ceramic sintered filter material, or metal sintered filter material. When the filter membrane 300 is arranged in multiple layers, the materials used in different layers of the filter membrane 300 can be the same or different. In this embodiment, the filter membrane 300 is arranged in a multi-layer structure, and the filtration accuracy of the filter membrane 300 is 1-5 μm.

[0062] In order to ensure the filtration efficiency, in one embodiment of the present invention, the water treatment and purification device further includes a first water distribution structure and a second water distribution structure.

[0063] Among them, reference Figure 1 and Figure 5 The first water distribution structure includes a first orifice plate 15 and a distribution cavity 16 arranged in the device body 10; wherein, the distribution cavity 16 and the magnetic purification cavity are separated by the first orifice plate 15, the water inlet 11 is connected to the distribution cavity 16, and a plurality of first water distribution holes 150 are provided on the first orifice plate 15, and the first water distribution holes 150 are arranged close to the permanent magnet rod 21.

[0064] During filtration, the incoming water enters the distribution chamber 16 through the water inlet 11 and enters the magnetic purification chamber through multiple water distribution holes. Since the first orifice plate 15 is arranged close to the permanent magnet rod 21, the incoming water can be evenly distributed to each permanent magnet rod 21, ensuring that there is sufficient flow around each permanent magnet rod 21, so that the permanent magnet rod 21 can effectively capture magnetic impurities and improve the magnetic purification efficiency. In addition, the uniformity of impurities on each permanent magnet rod 21 can be ensured, avoiding blockage or impurity falling problems caused by excessive impurities on local permanent magnet rods 21.

[0065] Specifically, the first orifice plate 15 is coaxially arranged at the bottom of the device body 10. The first orifice plate 15 and the inner wall of the device body 10 can be fixed by welding, connected by bolts and other connecting components, or integrally formed. The specific selection can be made according to actual needs.

[0066] Reference Figure 1 and Figure 6 The second water distribution structure includes a second orifice plate 17 and a water collection area 18 formed between the magnetic purification chamber and the precision purification chamber. The water collection area 18 is connected to the magnetic purification chamber; the water collection area 18 and the precision purification chamber are separated by the second orifice plate 17. The second orifice plate 17 is provided with a plurality of second water distribution holes 170, and the second water distribution holes 170 are arranged around the filter membrane 300.

[0067] During filtration, the water magnetically purified by the permanent magnet assembly 20 is collected in the water collection area 18 between the magnetic purification chamber and the precision purification chamber, and then enters the outer cavity 13 of the precision purification chamber through the second water distribution hole 170 on the second orifice plate 17. Since multiple second water distribution holes 170 are arranged around the filter membrane 300, the future flow can be evenly distributed to various parts of the filter membrane 300, thereby improving the filtration efficiency of the filter membrane 300. In addition, the uniformity of impurities at various positions of the filter membrane 300 can be ensured, effectively avoiding the blockage problem caused by excessive local impurities in the filter membrane 300.

[0068] Specifically, the second orifice plate 17 is coaxially arranged between the magnetic purification chamber and the precision purification chamber. The second orifice plate 17 and the inner wall of the device body 10 can be fixed by welding, or connected by connecting components such as bolts, or can be integrally formed. The specific selection can be made according to actual needs.

[0069] To facilitate water discharge, a water collection chamber 19 is provided within the device body 10. The water outlet hole 303 of the filter assembly 30 communicates with the water outlet 12 of the device body 10 through the water collection chamber 19. In actual operation, water filtered by the filter assembly 30 flows into the water collection chamber 19 through the water outlet hole 303 and is then discharged through the water outlet 12, which helps improve water discharge efficiency.

[0070] Specifically, the filter assembly 30 is provided with a group, and the water collecting chamber 19 and the precision purification chamber are separated by the upper cover plate 301 of the filter assembly 30.

[0071] In order to facilitate the cleaning, maintenance and replacement of the permanent magnet assembly 20 and the filter assembly 30, in one embodiment of the present invention, Figures 1 to 6 The device body 10 includes a first cylinder 100 and a second cylinder 101; wherein, one end of the first cylinder 100 is provided with a water inlet 11, and the other end is open, a magnetic purification chamber is formed in the first cylinder 100, and the permanent magnet assembly 20 is detachably connected to the first cylinder 100; openings are provided at both ends of the second cylinder 101, and one end of the second cylinder 101 is detachably spliced ​​with the open end of the first cylinder 100.

[0072] When the permanent magnet assembly 20 or the filter assembly 30 needs to be cleaned, repaired, or replaced, the cover 103 is removed from the second barrel 101, and then the filter assembly 30 is removed from the second barrel 101 and taken out from the open end of the second barrel 101 to achieve cleaning, repair, or replacement of the filter assembly 30; the second barrel 101 is removed from the first barrel 100, and then the permanent magnet assembly 20 is removed from the first barrel 100 and taken out from the open end of the first barrel 100 to achieve cleaning, repair, or replacement of the permanent magnet assembly 20.

Then, according to actual conditions, a single permanent magnet rod 21 can be removed from the fixing plate 22 for cleaning, repair or replacement, which is conducive to improving the convenience of cleaning, repair or replacement of the permanent magnet rod 21.
