Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0026] The following combination Figure 1-Figure 4 It should be noted that the present invention is not only applicable to the purification of condensed water, but also applicable to the purification of other water qualities. For ease of description, the following embodiments are all described using the purification of condensed water as an example.

[0027] Figure 1 This is one of the structural diagrams of the purification device provided by this utility model. Figure 1 A purification device provided by an embodiment of the present invention includes a shell 100 and a multi-stage filter assembly 200. The shell 100 has a cavity inside, and the two side walls of the cavity are respectively provided with a water inlet 110 and a water outlet 160; the multi-stage filter assembly 200 is arranged in sequence inside the cavity, and the filter assembly 200 includes a plurality of filters 210, and the multiple filters 210 are arranged at intervals, and the filters 210 in two adjacent stages are staggered.

[0028] In the above structure, condensate first enters the cavity from the water inlet 110 of the housing 100 and first passes through the first-stage filter 210. This stage of filter 210 generally uses a filter element with a coarser filtration accuracy (such as a wound filter element or a pleated filter element) to remove large particles of impurities and suspended matter. After preliminary filtration, the condensate continues to flow to the next-stage filter 210. In the multi-stage filter assembly 200, the filtration accuracy of the filter 210 increases step by step from the end close to the water inlet 110 to the end close to the water outlet 160, thereby being able to more finely remove tiny particles, colloids, corrosion products, etc. in the water. The staggered arrangement of adjacent two-stage filters 210 allows the water flow to more fully contact the filter material when passing through each stage of filter 210, thereby improving the filtration effect. After multi-stage filtration, the condensate flows out from the water outlet 160, and the water quality has been significantly improved at this time.

[0029] Through the design of the multi-stage filter assembly 200, the present invention allows filters 210 at different levels to select appropriate filter materials and filtration precision based on the water quality, thereby adapting to changes in water quality. For example, when the condensate contains a high amount of suspended solids, the filtration precision or number of primary filters 210 can be increased; when finer impurities need to be removed, the subsequent high-precision filters 210 can be used. The multi-stage filter assembly 200 effectively removes impurities and contaminants from the water, improving the effluent quality and thus reducing the amount of condensate that needs to be discharged due to substandard water quality. The design of step-by-step filtration and staggered arrangement allows for more comprehensive removal of various impurities from the water, improving the effluent quality. Furthermore, each filter stage 210 in the multi-stage filter assembly 200 performs a different filtration task, sharing the burden of a single filter 210. As a result, the filter material of each filter stage 210 wears relatively slowly, thereby extending the replacement cycle of the filter assembly 200.

[0030] In some possible embodiments, corrosion-resistant materials such as stainless steel and titanium alloys can be selected as the material for housing 100 to cope with corrosive media that may be present in the thermal system. Furthermore, to reduce heat loss and improve thermal energy efficiency, an insulation layer can be added to the exterior of housing 100. Specifically, the insulation layer can be made of rock wool, aluminum silicate, or the like.

[0031] In other possible embodiments, the multi-stage filter assembly 200 can be designed as a detachable and replaceable modular structure. Each module contains a certain number of filters 210, which can be combined and replaced according to actual needs. This design facilitates maintenance and upgrading, reducing maintenance costs. The flow channel inside the filter assembly 200 is optimized to ensure that the water flow can pass through each level of filter 210 evenly and stably. Fluid mechanics simulation technology is used to simulate and analyze the flow channel to find the optimal flow channel shape and size. In addition, an automatic cleaning system can be added to the interior of the cavity to regularly backwash or air wash the filter 210 to remove impurities and pollutants attached to the filter material.

[0032] Reference Figure 1 In some embodiments of the present invention, a plurality of baffles 130 are sequentially provided inside the cavity, a water inlet replenishment area 120 is formed between the baffle 130 near the water inlet 110 and the inner wall of the cavity, and a water outlet distribution area 150 is formed between the baffle 130 near the water outlet 160 and the inner wall of the cavity. The area between the water inlet replenishment area 120 and the water outlet distribution area 150 is divided into a plurality of water filtration areas 140 by the baffle 130, and the filter components 200 are arranged one by one inside the plurality of water filtration areas 140.

[0033] In the above structure, after condensate enters the cavity from the water inlet 110, it first enters the water inlet replenishment area 120. The design of this area allows for even distribution of water flow to the subsequent water filtration area 140, preventing the water flow from directly impacting the filter assembly 200 in a particular area, which could cause localized excessive pressure or uneven filtration. Water from the water inlet replenishment area 120 enters the various water filtration areas 140 through openings or gaps in the baffle 130. Each water filtration area 140 is equipped with a corresponding filter assembly 200. These filter assemblies 200 can be wound filter elements, pleated filter elements, ceramic filter elements, or metal sintered filter elements, with the appropriate type and combination selected based on water quality and treatment requirements. As the water flows through the filter assembly 200, impurities and contaminants retained by the filter assembly 200 are removed, and clean water continues to flow to the next water filtration area 140. After undergoing multi-stage filtration, the water ultimately enters the water outlet distribution area 150. The design of this area enables the water to flow out evenly from the water outlet 160, avoiding excessive or insufficient local water flow, which would affect the water quality and system stability.

[0034] This embodiment divides the cavity into multiple water filtration areas 140, and the water flow in each water filtration area 140 is relatively reduced, so that the filter assembly 200 can be in more complete contact with the water flow, thereby improving the filtration efficiency. The provision of the water inlet and water replenishment area 120 and the water outlet and water distribution area 150 makes the distribution of water flow in the system more uniform, avoiding the problem of system instability that may be caused by excessive or insufficient local water flow. The design of the baffle 130 also enhances the structural strength of the cavity, making the entire purification device more stable and reliable during operation. The modular design allows the filter assembly 200 in each water filtration area 140 to be individually disassembled and replaced, reducing maintenance costs and time. When a filter assembly 200 at a certain level fails or needs to be replaced, it is only necessary to close the relevant valves and disassemble the filter assembly 200 at that level without shutting down the entire system.

[0035] Figure 3 It is a structural schematic diagram of the partition of the purification device provided by the utility model.

[0036] Reference Figure 3 In some embodiments of the present invention, the baffle 130 is provided with a plurality of leaks 131 , and the plurality of leaks 131 are arranged in an array. A fixing frame 132 is provided inside each leak 131 , and the fixing frame 132 is used to install the filter 210 .

[0037] In the above structure, when water flows through the baffle 130, the water flow will be evenly distributed to each leak 131 because the multiple leaks 131 on the baffle 130 are arranged in an array. This design helps to achieve uniform distribution of water flow and avoid local water flow being too large or too small. Through the array arrangement of multiple leaks 131 and filters 210, efficient filtration of the water flow is achieved. Each filter 210 can work independently and jointly undertake the filtration task, thereby improving the overall filtration efficiency. When a part of the water flow is processed in a certain filter 210, the other parts of the water flow are processed simultaneously in other filters 210, thereby improving the overall filtration efficiency. Since the fixing frame 132 inside each leak 131 is equipped with a filter 210, when a filter 210 needs to be replaced or cleaned, the operation can be carried out separately without shutting down the entire system. This design reduces maintenance costs and time and improves the reliability and stability of the system.

[0038] Figure 4 It is a structural schematic diagram of the filter of the purification device provided by the utility model.

[0039] Reference Figure 4In some embodiments of the present invention, the filter 210 includes a filter housing 211, which includes a filter element 212. A mounting portion 213 is provided at the end of the filter housing 211. The mounting portion 213 is detachably connected to the fixing bracket 132. Specifically, the mounting portion 213 can be a bolt. During installation, the mounting portion 213 can be passed through the circular hole in the center of the fixing bracket 132 and then secured with a nut.

[0040] In the above structure, a mounting portion 213 is provided at the end of the filter housing 211, which is detachably connected to the mounting bracket 132. This detachable connection makes replacement and cleaning of the filter element 212 simple and quick, reducing maintenance costs and time. Users can regularly replace the filter element 212 or flexibly adjust the maintenance cycle based on water quality. Regular replacement of the filter element 212 maintains the filtration efficiency of the filter 210, preventing problems such as increased system pressure or poor water flow caused by clogging of the filter element 212, thereby improving the stability and reliability of the entire system.

[0041] Reference Figure 4 In some embodiments of the present invention, both ends of the filter housing 211 are provided with openings, and the side walls are hollow.

[0042] In the above structure, the opening design at both ends of the filter shell 211 allows water to enter the filter shell from either end, increasing the flexibility of the water flow. At the same time, the hollow design of the side wall allows the water to form a multi-directional flow inside the shell, which helps to achieve uniform distribution of the water flow. This uniform distribution not only improves the filtration efficiency, but also reduces local blockage or wear problems caused by uneven water flow. The hollow side wall can also increase the contact area between the water flow and the filter element, allowing more water to be filtered through the filter element at the same time. This design increases the filtration volume per unit time, thereby improving the overall filtration efficiency.

[0043] In some embodiments of the present invention, magnets are installed on the sidewalls of the filter housing 211. In this embodiment, when water flows through the filter 210, magnetic impurities (such as rust particles and magnetic bacteria) are attracted to the magnets on the sidewalls and adhere to the magnets' surfaces or nearby areas. This effectively separates these magnetic impurities from the water flow, improving the quality of the effluent water.

[0044] Figure 2 The second structural diagram of the purification device provided by the present invention is illustrated. Figure 2 In some embodiments of the present invention, a contraction portion 170 is provided at the bottom of the water outlet distribution area 150 , and the water outlet 160 is located at the center of the contraction portion 170 .

[0045] Specifically, the constricted portion 170 is an arc-shaped structure, with a lower center and higher sides. This arrangement allows water to first converge in the center of the constricted portion 170 upon entering the outlet distribution area 150 before being discharged through the outlet 160. Furthermore, the constricted portion 170 prevents liquid from remaining within the outlet distribution area 150.

[0046] Reference Figure 2 In some embodiments of the present invention, multiple support frames 300 are provided on the exterior of the housing 100, evenly distributed around the periphery of the housing 100. Each support frame 300 includes a leg 310, one end of which is connected to the housing 100 and the other end of which is provided with a footrest 320. The support frames 300 provide support for the device and also allow the water outlet 160 to be lifted off the ground, thereby improving water extraction. In other possible embodiments, the water outlet 160 is provided with a valve to control the discharge of filtered water.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
