[0002] The treatment and recovery of condensate are important factors affecting the safe operation, energy conservation and water conservation of the thermal system. For a thermal system with relatively high parameters, due to the good quality of boiler feed water, the pollution of condensate generally consists of a large amount of metal corrosion products, a small amount of non-magnetic suspended solids and trace amounts of salts.

In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0029] The following combines Figures 1-6 to describe the purification device of the present utility model. It should be noted that the present utility model is not limited to purifying condensate, and other liquids are also applicable.

[0030] Figure 1 Fig. 1 is a schematic structural diagram of the purification device provided by an embodiment of the present utility model. Figure 2 Illustrates Figure 1 the top view of the structure shown. Referring to Figure 1 and Figure 2 , a purification device provided by an embodiment of the present utility model includes a housing 100, a filter element 200, and a plurality of magnets 300. The interior of the housing 100 has a cavity, and is provided with a water inlet 130 and a water outlet 140 communicating with the cavity; the filter element 200 is disposed inside the cavity, dividing the cavity into a water filtering cavity 110 and a water collecting cavity 120, the water outlet 140 communicates with the water filtering cavity 110, and the water outlet 140 communicates with the water collecting cavity 120; a plurality of magnets 300 are spaced apart and disposed inside the water collecting cavity 120.

[0031] In the above structure, after the condensate enters the cavity of the housing 100 through the water inlet 130, it first encounters the magnet 300. The magnet 300 uses the principle of magnetic attraction to adsorb the metal corrosion products (such as rust, iron filings, etc.) contained in the condensate onto the surface of the magnet 300. Since the metal corrosion products generally account for more than 80% of the condensate pollutants and are mostly magnetic substances, the magnet 300 can very effectively remove these pollutants. The condensate adsorbed by the magnet 300 enters the filter element 200, and the filter element 200 divides the cavity into a water filtering cavity 110 and a water collecting cavity 120. In the water filtering cavity 110, the filter element 200 physically filters non-magnetic impurities and the like in the condensate through its porous structure or specific material (such as fiber, ceramic, etc.), so that the condensate is further purified. The filtered condensate then enters the water collecting cavity 110. The purified condensate flows out from the water collecting cavity 110 through the water outlet 140 for use in the subsequent thermal system or for other treatments.

[0032] The utility model reduces the content of metal corrosion products in the condensate water significantly after the adsorption treatment by the magnet 300, improves the water quality remarkably, alleviates the corrosion and wear of the thermal system equipment, extends the service life of the equipment, and ensures the safe operation of the thermal system. In addition, the purified condensate water can be directly recycled into the thermal system, reducing the phenomenon of condensate water discharge caused by excessive metal corrosion products, improving the recycling rate of condensate water, and reducing water resource waste.

[0033] In some possible embodiments, according to the characteristics of pollutants in the condensate water, a more efficient filter element 200 material, such as nanofibers, can be selected to improve the filtration effect. At the same time, the structural design of the filter element 200 can also be optimized, such as increasing the number of filtration layers, adopting a gradient pore size distribution, etc., to improve the filtration accuracy and efficiency. According to the content and distribution characteristics of metal corrosion products in the condensate water, the layout and quantity of the magnets 300 are adjusted. For example, the quantity of the magnets 300 is increased in the area with a higher content of metal corrosion products to ensure sufficient adsorption. At the same time, a combination of magnets 300 with different magnetic properties can be considered to improve the adsorption effect on different types of metal corrosion products. Secondly, in order to avoid excessive adsorption of metal corrosion products on the surface of the magnets 300 and affect the purification effect, an automatic cleaning and regeneration system can be designed. By starting the cleaning program regularly or automatically according to the monitoring data, the pollutants on the surface of the magnets 300 are removed by means of high-pressure water flow or mechanical scraping, etc., to restore the adsorption capacity of the magnets 300. At the same time, the pollutants washed down can be considered for recovery treatment to reduce environmental pollution.

[0034] In some embodiments of the utility model, the magnet 300 is detachably arranged inside the water collecting cavity 120 through a magnet limiting member 400.

[0035] In the above structure, the adsorption efficiency of the magnet 300 may decrease after long-term use due to excessive adsorption of metal corrosion products. Through the detachable design, the user can easily take out the magnet 300 for cleaning or replacement, reducing the maintenance cost and improving the utilization rate of the equipment. Secondly, according to different purification requirements and the quality of condensate water, through the detachable design, the user can flexibly adjust the quantity and layout of the magnets 300 to achieve the best purification effect. At the same time, this also provides more choices and possibilities for customization for the user. Moreover, through the detachable design, when replacing or cleaning the magnet 300, it is not necessary to shut down the entire purification device. Only the relevant components need to be disassembled for operation, thus reducing the production downtime caused by equipment maintenance.

[0036] Specifically, the shape of the magnet 300 can be optimized according to the structure of the water collecting cavity 120 and the distribution characteristics of metal corrosion products. For example, magnets 300 of different shapes such as strip-shaped, arc-shaped or mesh-shaped can be adopted to increase the contact area with the condensed water and improve the adsorption efficiency. At the same time, combinations of magnets 300 with different magnetic properties can also be designed to deal with different types of metal corrosion products. The design of the magnet limiting member 400 should ensure the stability and detachable property of the magnet 300 in the water collecting cavity 120. Different fixing methods such as card slots, slide rails, magnetic attraction, etc. can be considered to firmly fix the magnet 300 in the water collecting cavity 120 while facilitating its disassembly. In addition, the limiting member can also be designed with a sealing structure to prevent the condensed water from leaking into the installation area of the magnet 300.

[0037] Figure 3 Fig. shows one of the structural schematic diagrams of the magnet limiting member of the purification device provided by the embodiment of the present invention. Figure 4 Fig. shows another structural schematic diagram of the magnet limiting member of the purification device provided by the embodiment of the present invention.

[0038] Referring to Figure 3 and Figure 4 In some embodiments of the present invention, the magnet limiting member 400 includes a limiting frame 410. The limiting frame 410 is arranged inside the water collecting cavity 120. A plurality of limiting rings 420 are arranged at intervals on the limiting frame 410, and the limiting rings 420 are arranged in one-to-one correspondence with the magnets 300.

[0039] Specifically, the limiting frame 410 includes a plurality of limiting rods. The plurality of limitings are arranged in a circumferential array, and a limiting ring 420 is provided on each limiting rod. With such an arrangement, the magnets 300 can be arranged in a circumferential array, so that the spacing between the magnets 300 can be made more uniform, and thus the iron impurities in the condensed water can be cleaned more comprehensively. In some possible embodiments, the limiting frame 410 includes two limiting rods, and the two limiting rods are arranged in a cross form. A limiting ring 420 is provided at the intersection of the two limiting rods, and at least one limiting ring 420 is also provided on the remaining parts of each limiting rod (as shown in Figure 3 ). In some other possible embodiments, the limiting frame 410 includes three limiting rods, and the three limiting rods are arranged in a circumferential array. A limiting ring 420 is provided at the intersection of the three limiting rods, and at least one limiting ring 420 is also provided on the remaining parts of each limiting rod (as shown in Figure 4 ). It should be noted that the number of limiting rods included in each limiting frame 410 is not limited, and the number of limiting rings 420 on each limiting rod is also not limited. The specific number can be adaptively adjusted according to the shape and size of the water filtering cavity 110.

[0040] In some possible embodiments, an elastic sleeve is provided inside the limiting ring 420, and the elastic sleeve is used to limit the magnet 300. Specifically, the elastic sleeve is a cylindrical structure, and its shape should be adapted to the shape of the magnet 300. For example, when the magnet 300 is a cylindrical structure, the elastic sleeve is a circular ring structure. When the magnet 300 is a cuboid structure, the elastic sleeve can be a square ring structure.

[0041] In the above structure, the elastic sleeve can closely fit the limiting magnet 300, providing additional friction force to prevent the magnet 300 from moving under vibration or impact, enhancing the stability of the limit. Secondly, as an intermediate medium, the elastic sleeve can absorb and disperse external impact forces, playing a buffering and protective role for the limiting magnet 300 and the limiting ring 420, and extending the service life. Moreover, in some application scenarios, due to reasons such as temperature changes and material aging, the magnet 300 or the limiting ring 420 may undergo minor deformations. The elastic sleeve can adapt to these minor deformations and maintain the continuity of the limiting function. Finally, the design of the elastic sleeve can also make the installation and replacement of the limiting magnet 300 more convenient, without the need for complex adjustments or modifications to the limiting ring 420.

[0042] Figure 5 It is a cross-sectional view of the filter element of the purification device provided by the present utility model.

[0043] Refer to Figure 5 In some embodiments of the present utility model, the filter element 200 includes a filter element housing 210. Inside the filter element housing 210, a filter layer 220 and a carbon layer 230 are provided, and the filter layer 220 is arranged outside the carbon layer 230. Specifically, the core housing 210 is a cylindrical tube structure, and the filter layer 220 is also a cylindrical tube structure and is fixedly arranged on the inner wall of the core housing 210. The carbon layer 230 is filled inside the filter layer 220. Specifically, the material of the filter layer 220 can specifically be filter cloth, sintered metal, or sintered ceramic.

[0044] In the above solution, the filter layer 220 is used for precision filtration, and its filtration accuracy can be 1μm - 20μm. The filter layer 220 can effectively remove non-magnetic impurities in water and magnetic substances that escape from magnet adsorption, improving the quality of condensate water. The pore structure of the filter layer 220 is conducive to the flow of water and can intercept fine particulate matter. The carbon layer 230 has a strong adsorption capacity due to its porosity and can adsorb colloidal silicon, organic matter, etc. in water, further purifying the water quality and improving the quality of condensate water. In this embodiment, through the preliminary adsorption of the magnet 300, the amount of impurities entering the filter layer 220 and the carbon layer 230 is reduced, thus reducing the burden on the filter layer 220 and the carbon layer 230, which helps to extend the service life of the entire filter element 200. In some possible embodiments, the filter element housing 210 is in a hollow shape and communicates with the condensate water. The carbon layer 230 includes charcoal, bamboo charcoal or activated carbon, which is specifically selected according to the actual situation.

[0045] Figure 6 This is a second schematic structural diagram of the purification device provided by the embodiment of the present invention. Refer to Figure 6 , in some embodiments of the present invention, a base 500 is provided at the bottom of the housing 100. The base 500 is made of some materials with certain elasticity, such as rubber, etc. In some other possible embodiments, a mounting bracket 600 is provided on the side of the housing 100. Threaded holes are provided on the mounting bracket 600, and the present invention can be suspended by bolts. In some other possible embodiments, connectors 131 are provided at the ends of the water inlet 130 and the water outlet 140 that are away from the housing 100. The connectors 131 can specifically be flanges, and are connected to other pipes through the flanges.
