Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a water treatment and purification device. Background Technology

[0002] With the continuous development of industrial and civil heating systems, the effective treatment of condensate, drains, and circulating water in the heating network has become a key factor in ensuring system efficiency and extending equipment lifespan. However, in practical applications, the discharge of these waters due to poor quality is common, resulting in a waste of heat and water resources. To improve water quality and reduce discharge, the treatment processes for condensate, drains, and circulating water in the heating network typically employ filtration and desalination. Traditional filtration devices have poor filtration efficiency, causing problems such as corrosion, scaling, and blockage in the heating system, which negatively impacts the system's safety, energy consumption, and water consumption. Furthermore, poor filtration efficiency can also lead to shortened regeneration cycles and resin contamination in desalination equipment. The main sources of pollution in condensate, drains, and circulating water in the heating network are introduced from raw water, system leaks, and system corrosion. System corrosion generally accounts for more than 80% of the pollution, with most corrosion products being ferromagnetic substances.

[0003] Currently, condensate, hydrophobic water, and circulating water in heating networks are filtered using cartridge-type iron removal filters. The filter cartridges are generally made of 1-10μm filter membranes such as polypropylene (PP), polyethersulfone (PES), polytetrafluoroethylene (PTFE), glass fiber, ceramic sintering, and stainless steel sintering. The smaller the pore size of the filter membrane, the better the filtration effect.

[0004] However, reducing the pore size of the filter membrane can improve filtration accuracy, but it will increase the operating pressure difference, which will place higher demands on the iron content of the influent, reduce the dirt holding capacity and the service life of the filter element.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0033] The following is combined Figures 1-3 This invention describes a water treatment and purification device.

[0034] An embodiment of this utility model provides a water treatment and purification device, such as... Figure 1 As shown, the water treatment and purification device includes a purification body 100 and a multi-stage filter element 200 disposed within the purification body 100.

[0035] The purification body 100 has an inlet 101 and an outlet 102. A multi-stage filter element 200 is arranged inside the purification body 100. The multi-stage filter element 200 includes a magnetic filter component 210 and a membrane filter component 220 connected to the upper part of the magnetic filter component 210. The membrane filter component 220 has a first flow channel 223 inside, and the magnetic filter component 210 has a second flow channel 214 inside. The second flow channel 214 is connected to the first flow channel 223 and the outlet 102, respectively.

[0036] Understandably, incoming water enters the purification unit 100 through inlet 101 and is first adsorbed by the external magnetic field of the low-level magnetic filter component 210. The low-level magnetic filter component 210 first uses a strong external magnetic field to efficiently adsorb ferromagnetic particles (such as rust, corrosion products, etc.) in the incoming water, removing ferromagnetic substances from the water and greatly reducing the impurity load in subsequent treatment steps. The water after magnetic adsorption treatment enters the high-level membrane filter component 220. The membrane filter component 220 then performs fine filtration on the water that has been initially magnetically filtered, filtering out the remaining suspended solids in the water and effectively removing non-magnetic microparticles and other dissolved substances to ensure the purity of the water. The filtered water enters the membrane filter component 220 and enters the second flow channel 214 inside the magnetic filter component 210 through the first flow channel 223. The internal magnetic field of the magnetic filter component 210 magnetizes the water and the medium in the water in the second flow channel 214, producing purified water, which flows out from the drain outlet 102. It should be noted that the external magnetic field of the magnetic filter component 210 is generated on the outside of the magnetic filter component 210, and the internal magnetic field of the magnetic filter component 210 is generated in the second flow channel 214 inside the magnetic filter component 210.

[0037] The water treatment and purification device provided in this embodiment of the utility model has a multi-stage filter element 200 installed in the purification body 100. The multi-stage filter element 200 includes a magnetic filter element 210 at a low position and a membrane filter element 220 at a high position. The incoming water is adsorbed by the external magnetic field of the magnetic filter element 210 and then enters the membrane filter element 220 for filtration. The magnetic filter element 210 at the low position adsorbs ferromagnetic particles contained in the incoming water, thereby reducing the pollutant load on the surface of the membrane filter element 220, thereby reducing the risk of clogging of the membrane filter element 220, improving the dirt holding capacity and the service life of the filter element. Furthermore, the water filtered by the membrane filter element 220 enters the interior of the magnetic filter element 210, where the water and the medium in the water are magnetized to produce purified water, thereby improving the quality of the effluent.

[0038] It should be noted that this embodiment utilizes the magnetic adsorption, membrane filtration, and magnetization of the multi-stage filter element 200 to classify and treat impurities in the water in multiple stages. Magnetic adsorption can remove ferromagnetic substances from the water, the filter membrane removes non-magnetic and weakly magnetic particles from the water, and magnetization can slow down the corrosion and scaling rate of the thermal system. Thus, the multi-stage filter element 200 combines the magnetic filtration component 210 and the membrane filtration component 220, which facilitates the replacement of traditional filter elements. Multi-stage treatment can improve the quality of the effluent, extend the service life of the filter element, reduce the number of filter membrane replacements, and reduce operating costs.

[0039] In one embodiment of this utility model, such as Figure 2As shown, the magnetic filter component 210 includes an inner cylinder 211 of the magnetic filter element, an outer cylinder 212 of the magnetic filter element, and a magnet 213 disposed between the inner cylinder 211 and the outer cylinder 212 of the magnetic filter element. A second flow channel 214 is formed inside the inner cylinder 211 of the magnetic filter element.

[0040] Optionally, both the inner cylinder 211 and the outer cylinder 212 of the magnetic filter element are hollow cylindrical structures, forming an annular cavity between them. The magnet 213 is annular and arranged within the annular cavity. The internal cavity of the inner cylinder 211 serves as the second flow channel 214. The lower end of the inner cylinder 211 extends out of the outer cylinder 212, and the opening at the lower end of the inner cylinder 211 serves as the outlet 2141.

[0041] Specifically, the magnet 213 includes multiple magnetic units stacked along the axial direction, each magnetic unit including N-pole magnetic blocks and S-pole magnetic blocks arranged circumferentially.

[0042] It is understood that the inner cylinder 211 and the outer cylinder 212 of the magnetic filter element are arranged vertically, and the magnet 213 includes multiple magnetic units arranged vertically in a stacked manner. Each magnetic unit is ring-shaped and includes at least one pair of magnetic blocks. Each pair of magnetic blocks includes an N-pole magnetic block and an S-pole magnetic block arranged opposite to each other.

[0043] In this embodiment, the N-pole magnetic block and the S-pole magnetic block can be permanent magnets 213. The permanent magnets 213 are made of rare earth permanent magnet materials such as neodymium iron boron and samarium cobalt, and the magnetic field strength can be selected from 3000-10000GS. The permanent magnets 213 are encapsulated between the inner cylinder 211 and the outer cylinder 212 of the magnetic filter element.

[0048] It should be noted that the magnetic filter component 210 and the membrane filter component 220 are connected by a connecting ring 230, and the magnetic filter component 210 and the membrane filter component 220 can be disassembled and installed separately for easy replacement.

[0049] Furthermore, the inner wall of the connecting ring 230 is provided with an annular seal to improve the sealing performance of the connection between the magnetic filter component 210 and the membrane filter component 220.

A water inlet 101 communicating with the water inlet cavity 104 is provided at the bottom of the purification body 100.

[0051] Specifically, the water inlet 101 is located in the middle of the bottom plate of the purification body 100, and multiple multi-stage filter elements 200 are arranged circumferentially on the outside of the water inlet 101.

[0052] In this embodiment, the water inlet 101 is provided with a water inlet pipe 300, and the end of the water inlet pipe 300 located inside the purification body 100 has a plurality of circumferentially arranged water inlet holes 310.

[0053] Understandably, the water inlet pipe 300 is installed in the middle of the bottom plate of the purification body 100. The water inlet pipe 300 is a hollow structure with an opening at the bottom. The end of the water inlet pipe 300 outside the purification body 100 (i.e., the lower end) serves as the water inlet end, and the end of the water inlet pipe 300 inside the purification body 100 (i.e., the upper end) serves as the water outlet end. The side wall of the water outlet end of the water inlet pipe 300 is provided with multiple water inlet holes 310 arranged in a circumferential direction. The incoming water enters the water outlet end through the water inlet end, and after being diverted by the multiple water inlet holes 310 arranged in a circumferential direction, it enters the outer wall of the multi-stage filter element 200 for adsorption.

[0054] Furthermore, multiple water inlet holes 310 are evenly distributed circumferentially; of course, multiple multi-stage filter elements 200 can also be evenly distributed circumferentially with the axis of the water inlet pipe 300 as the center.

[0055] Understandably, the water inlet 310 is located around the water inlet pipe to better control the direction of water flow and improve the magnetic adsorption effect.

[0056] In one embodiment of this utility model, such as Figure 1 and Figure 3As shown, a horizontal partition 110 is provided at the bottom of the purification body 100 to divide the interior of the purification body 100 into a water collection chamber 103 and an inlet chamber 104 located above the water collection chamber 103. A multi-stage filter element 200 is disposed in the inlet chamber 104, and the lower end of the multi-stage filter element 200 is connected to the water collection chamber 103. The drain outlet 102 is connected to the water collection chamber 103.

[0057] It is understandable that the second flow channel 214 inside the magnetic filter component 210 is connected to the water collection chamber 103. The purified water flows out from the lower part of the second flow channel 214, collects in the water collection chamber 103, and flows out through the drain outlet 102.

[0058] In one embodiment of this utility model, such as Figure 1 As shown, the side wall of the purification body 100 has a positioning member 120, and the upper end of the multi-stage filter element 200 is connected to a fixing member 130, which is connected to the positioning member 120.

[0059] Specifically, the positioning component 120 is a positioning plate set on the side wall of the purification body 100, the upper end of the multi-stage filter element 200 is provided with fixing bolts 240, the fixing component 130 is a fixing plate, all the fixing bolts 240 of the multi-stage filter element 200 are connected to the fixing plate, the edge of the fixing plate is set on the positioning plate and fixed by connecting bolts.

[0060] Furthermore, the horizontal partition 110 has a plurality of first mounting holes 111, the number of which is equal to the number of multi-stage filter elements 200, and their positions correspond one-to-one. The lower end of the multi-stage filter element 200 is set in the corresponding first mounting hole 111, and the outlet 2141 at the lower end of the multi-stage filter element 200 is connected to the water collection chamber 103. Thus, the multi-stage filter element 200 is fixed by the horizontal partition 110 and the fixing plate, which facilitates the replacement of the multi-stage filter element 200.

[0061] Understandably, the horizontal partition 110 has a second mounting hole 112 in the middle, through which the water inlet pipe 300 passes. It should be noted that the bottom plate of the purification body 100 is also provided with a third mounting hole for the water inlet pipe 300 to pass through.

[0062] In this embodiment, the water inlet pipe 300 is welded and sealed to the bottom plate and horizontal partition 110 of the purification body 100, and the lower end of the multi-stage filter element 200 is sealed to the first mounting hole 111 on the horizontal partition 110 by means of thread or plug-in connection.

[0063] In one embodiment of this utility model, such as Figure 1 As shown, the purification body 100 includes a purification cylinder 140 and a cylinder cover plate 150 connected to the purification cylinder 140.

[0065] It is understandable that the purification cylinder 140 and the cylinder cover 150 are connected by a detachable flange, which facilitates opening the cylinder cover 150 to maintain the multi-stage filter element 200 inside the purification cylinder 140. It should be noted that the maintenance of the multi-stage filter element 200 may include inspection, removal and replacement of the multi-stage filter element 200.

[0066] In one specific embodiment of this utility model, such as Figures 1 to 3 As shown, the water treatment and purification device includes a purification body 100 and multiple multi-stage filter elements 200 disposed within the purification body 100.

The multi-stage filter element 200 has magnetic adsorption, precision filtration and magnetization functions. Magnetic adsorption removes ferromagnetic substances in the water, the membrane filtration component performs precision filtration of the remaining suspended solids in the water, and magnetization changes the chemical reaction system of the medium in the water, slowing down the corrosion and scaling rate of water vapor system equipment and pipelines.

[0070] It is understood that the multi-stage filter element 200 includes a magnetic filtration component 210 and a membrane filtration component 220. The water to be treated enters the inlet pipe 300 from the inlet 101 and is diverted through the inlet hole 310. It flows evenly from bottom to top along the outer wall of the multi-stage filter element 200 in the purification cylinder 140. After being adsorbed by the external magnetic field of the magnetic filtration component 210, it enters the membrane filtration component 220. After being filtered by the membrane filtration component 220, it enters the inner hole of the magnetic filtration component 210. After being magnetized by the magnetic field inside the magnetic filtration component 210, it flows out from the lower hole of the multi-stage filter element 200, is collected in the water collection chamber 103, and flows out through the drain outlet 102.

[0071] It should be noted that this embodiment mainly removes ferromagnetic, organic, and inorganic suspended solids from the water. The maximum designed influent iron content is ≤2000μg / L, which can significantly reduce wastewater discharge from the thermal system. The maximum designed operating pressure difference is ≤0.15MPa. When the operating pressure difference is ≥0.15MPa, the multi-stage filter element 200 should be replaced, or the multi-stage filter element 200 can be removed, cleaned, and reused.

[0072] The water treatment and purification device provided in this embodiment of the utility model uses magnetic adsorption, precision membrane filtration and magnetization processes to classify and treat impurities in water. Magnetic adsorption can remove ferromagnetic substances in water, precision filtration can remove residual suspended particles in condensed water, and magnetization can slow down corrosion and scaling of the thermal system. Thus, classified filtration can improve the quality of effluent, extend the service life of multi-stage filter elements, and reduce operating costs. Furthermore, multi-stage filter elements can be reused for a long time, reducing waste and making it green and environmentally friendly.
