Description

Technical Field

[0001] This utility model relates to the field of heat exchange technology, and in particular to a condenser shell, a condenser heat exchange device, and a gas-fired hot water equipment. Background Technology

[0002] Gas-fired water heaters heat water by passing the high-temperature flue gas generated by gas combustion through a heat exchanger, thereby exchanging heat between the flue gas and the water flowing through the exchanger. To fully utilize the heat from the flue gas, condensing gas-fired water heaters are becoming increasingly widely used.

[0003] Condensing gas water heaters add a condensing heat exchange device compared to conventional gas water heaters. Existing technology provides a condensing heat exchange device, which includes a condensing shell, a condensing heat exchanger, an atomizer, and a neutralizer. The condenser shell has a condensing chamber and a filter chamber connected vertically, and a flue gas chamber and an atomizing chamber connected vertically. The condensing heat exchanger is located in the condensing chamber, and the chamber wall of the condensing chamber is provided with a flue gas inlet. The two ends of the condensing heat exchanger are connected in series to the water inlet pipe of the main heat exchanger of the gas-fired hot water equipment. After passing through the main heat exchanger, the flue gas flows into the condensing chamber through the flue gas inlet and exchanges heat with the condensing heat exchanger to preheat the water flowing to the main heat exchanger. The flue gas after heat exchange flows into the flue gas chamber. A neutralizer is installed in the filter chamber to neutralize and filter the condensate produced by condensation. The atomizing chamber is located on one side of the condensing chamber and is connected to the condensing chamber through a water passage. The atomizer is located in the atomizing chamber, and the condensate filtered by the neutralizer in the filter chamber flows into the atomizing chamber through the water passage and is atomized by the atomizer in the atomizing chamber to form water mist. The water mist is sprayed upward into the flue gas chamber and mixes with the flue gas in the flue gas chamber before flowing out through the flue gas outlet.

[0004] In existing condensation heat exchange devices, to prevent unfiltered condensate from flowing into the atomizing chamber, a partition rib is typically integrally protruding from the upper wall of the filter chamber. This partition rib divides the filter chamber into a main filter chamber and a water passage chamber. The upper end of the main filter chamber connects to the condensation chamber, and the lower end connects to the water passage chamber. The water passage chamber connects to the atomizing chamber, and a neutralizer is installed in the main filter chamber. However, this design results in a complex condenser shell structure and higher manufacturing costs. Utility Model Content

[0048] Example 1

[0049] This embodiment provides a condensing heat exchange device that can be applied to condensing gas-fired water heaters to further condense and cool the flue gas after heat exchange, improve the utilization rate of flue gas heat, enhance the heat exchange effect of the gas-fired water heater, and reduce the processing and maintenance costs of the condensing heat exchange device.

[0050] like Figure 1 As shown, the condensing heat exchange device includes a condensing shell 100, a condensing heat exchanger 200, a filter 300, and an atomizer 400. The condensing shell 100 has a condensing chamber 5 and a filter chamber 13 connected vertically, as well as a flue gas chamber 7 and an atomizing chamber 6 connected vertically. The wall of the condensing chamber 5 has a flue gas inlet 8 communicating with it. The upper end of the condensing shell 100 has a flue gas inlet 9 communicating with the flue gas chamber 7, and the lower end of the flue gas chamber 7 communicates with the condensing chamber 5. The filter chamber 13 and the atomizing chamber 6 are arranged horizontally side-by-side, and the upper end of the filter chamber 13 has a water inlet 112 communicating with the condensing chamber 5. The side of the filter chamber 13 has a water outlet 113 communicating with the atomizing chamber 6.

[0051] A condenser heat exchanger 200 is installed in the condenser chamber 5 to condense and exchange heat with the flue gas entering the condenser chamber 5 from the flue gas inlet 8. Both ends of the condenser heat exchanger 200 extend outside the condenser shell 100. A filter 300 is installed in the filter chamber 13 to filter the condensate entering the filter chamber 13. An atomizer 400 is installed in the atomizing chamber 6, and the water inlet of the atomizer 400 is connected to the atomizing chamber 6. The mist outlet is set upward. The atomizer 400 is used to atomize the condensate entering the atomizing chamber 6, and the water mist generated by atomization can flow upward to the exhaust chamber 7 to mix with the flue gas entering the exhaust chamber 7. The mixed flue gas and water mist are discharged through the exhaust port 9.

[0052] like Figure 1 and Figure 2As shown, in this embodiment, the condenser housing 100 has a filter housing 1, which has a filter chamber 13, an inlet 112 connected to the top of the filter chamber 13, and a water outlet 113 connected to the side of the filter chamber 13. The filter chamber 13 has a mounting slot 111 on its wall. The condenser housing 100 also includes a partition plate 2 detachably connected to the filter housing 1. The partition plate 2 is inserted into the mounting slot 111 and divides the filter chamber 13 into a main filter chamber 131 and a water outlet chamber 132. A water passage hole 21 is formed between the lower end of the partition plate 2 and / or between the partition plate 2 and the bottom of the filter chamber 13. The water passage hole 21 connects the main filter chamber 131 and the water outlet chamber 132. The main filter chamber 131 is connected to the inlet 112, and the water outlet chamber 132 is connected to the water passage hole 21 and the water outlet 113, respectively.

[0053] The condenser housing 100 and condenser heat exchange device provided in this embodiment divide the filter chamber 13 into a main filter chamber 131 and a water passage chamber 132 by setting a partition plate 2. This facilitates the installation and positioning of the filter 300 in the filter chamber 13 while preventing unfiltered condensate from flowing into the atomizing chamber 6, thus better ensuring the filtration effect of the condensate. Since the partition plate 2 is detachably connected to the outer shell, it simplifies the structure of the condenser housing 100, thereby reducing the processing difficulty and cost of the condenser housing 100. Furthermore, since the filter chamber 13 has a mounting slot 111, the partition plate 2 is inserted into the mounting slot 111, which simplifies the installation of the partition plate 2 in the filter chamber 13. This ensures the installation accuracy of the partition plate 2 while reducing the assembly difficulty of the condenser housing 100.

[0054] It is worth noting that in this embodiment, the filter 300 may have the function of neutralizing the acidity of the condensate, or the function of filtering impurities in the condensate, or a combination of both. The arrangement of the filter 300, condensation chamber 5, atomizing chamber 6 and exhaust chamber 7 in the condensation shell 100 can refer to the arrangement in the prior art. The installation of the condensation heat exchanger 200 and atomizer 400 in the condensation shell 100 can also refer to the structure in the prior art. This is not the focus of the improvement of this utility model, and no limitation or improvement is made here. This utility model only describes the filter shell 1 and its relative structure.

[0055] like Figure 2As shown, in one embodiment, the filter housing 1 includes a filter cylinder portion 11 with an open lower end and a bottom cover 12 detachably disposed at the lower end of the filter cylinder portion 11. The bottom cover 12 and the filter cylinder portion 11 together form a filter chamber 13. A mounting slot 111 is disposed in the filter cylinder portion 11, which extends vertically. That is, a water inlet 112 is provided at the upper end of the filter cylinder portion 11, and a water outlet 113 is provided on the side of the filter cylinder portion 11. This arrangement allows both the partition plate 2 and the filter 300 to be inserted into the filter chamber 13 through the open lower end of the filter cylinder portion 11, improving the assembly efficiency of the partition plate 2 and the filter 300.

[0056] The bottom cover 12 includes a bottom plate portion 121 and a surrounding wall portion 122 extending upward around the periphery of the bottom plate portion 121. The bottom plate portion 121 forms the bottom of the filter chamber 13, and the surrounding wall portion 122 surrounds the outside of the filter cylinder portion 11 and is detachably connected to the filter cylinder portion 11. This arrangement facilitates the installation and positioning of the bottom cover 12 and the filter cylinder portion 11, improving assembly accuracy and efficiency.

[0057] In one embodiment, the inner wall of the enclosure 122 is provided with an internal thread, and the outer wall of the filter cylinder 11 is provided with an external thread. The internal and external threads engage, and the enclosure 122 is screwed onto the outer side of the filter cylinder 11. By screwing the bottom cover 12 onto the outer side of the filter cylinder 11, the installation stability and reliability of the bottom cover 12 and the filter cylinder 11 can be effectively improved. Simultaneously, this arrangement facilitates the stable clamping of the filter 300 between the bottom cover 12 and the top wall of the filter cylinder 11, preventing the filter 300 from shaking in the vertical direction and improving the installation stability and reliability of the filter 300. In other embodiments, the enclosure 122 and the filter cylinder 11 can also be snapped together.

[0058] In one embodiment, the upper end of the filter 300 abuts against the top wall of the filter chamber 13 and the lower end abuts against the bottom cover 12, so that the filter 300 is clamped between the top wall of the filter chamber 13 and the bottom cover 12, preventing the filter 300 from shaking in the vertical direction. Furthermore, a rib 16 protrudes from the wall of the filter main chamber 131, and multiple ribs 16 are spaced apart circumferentially along the filter main chamber 131. The ribs 16 can abut against the outer side of the filter 300 to limit the horizontal shaking of the filter 300 within the filter chamber 13, and also reduce the contact area between the filter housing assembly and the filter 300, thereby facilitating the installation and removal of the filter 300 in the filter main chamber 131.

[0059] like Figures 2 to 4As shown, a baffle ring 14 extends downward from the periphery of the inlet 112. The baffle ring 14 is inserted into the inner side of the inlet end of the filter 300 to better prevent the internal structure of the filter 300 from moving upward. The baffle ring 14 is provided with multiple water passage notches 141 at intervals along the circumference to improve the smoothness of water flow from the condensation chamber 5 to the main filter chamber 131.

[0060] In one embodiment, a lower boss 123 protrudes from the bottom plate 121. The lower boss 123 is coaxial with and spaced apart from the enclosure wall 122. The lower boss 123, the bottom plate 121, and the enclosure wall 122 cooperate to form a sealing ring groove. An annular seal 3 is provided in the sealing ring groove, and the lower end of the filter cylinder 11 abuts against the annular seal 3. By providing the annular seal 3, the connection between the filter cylinder 11 and the bottom cover 12 can be sealed, preventing condensate from seeping out through the connection between the filter cylinder 11 and the bottom cover 12, thus improving the safety and reliability of the condensation heat exchange device. At the same time, by providing the sealing ring groove, the installation stability and reliability of the annular seal 3 can be improved.

[0061] In other embodiments, the annular seal 3 may be disposed between the filter cylinder portion 11 and the enclosure portion 122, or it may be disposed between the filter cylinder portion 11 and the lower boss portion 123.

[0062] In one embodiment, a drain outlet 1211 is provided at the bottom of the filter chamber 13. The drain outlet 1211 can be selectively opened or blocked. The drain outlet 1211 facilitates the discharge of condensate in the filter chamber 13, thereby facilitating the disassembly and maintenance of the internal structure of the filter housing 1. Specifically, the drain outlet 1211 is provided on the bottom plate portion 121 and is located inside the lower boss portion 123.

[0063] Furthermore, the lower end of the filter 300 abuts against the lower boss portion 123, that is, the lower end of the filter 300 is spaced apart from the base plate portion 121, to prevent the filter 300 from blocking the drain outlet 1211 and to ensure smooth drainage. In other embodiments, the lower end of the filter 300 may abut against the base plate portion 121 and be located inside the lower boss portion 123.

[0064] To ensure convenient drainage, a drain pipe section 124 protrudes from the lower side of the base plate 121. The inner cavity of the drain pipe section 124 forms a drainage channel, and the upper end of the drainage channel is connected to the drain outlet 1211. This allows for the connection between the condensate shell 100 and the drain pipe.

[0065] like Figure 4 and Figure 5As shown, in one embodiment, the mounting slot 111 includes a top slot 1111 formed on the top wall of the filter chamber 13, and the upper end of the partition plate 2 is inserted into the top slot 1111; the mounting slot 111 also includes a side slot 1112 formed on the side wall of the filter chamber 13, the side slots 1112 extend in the vertical direction and are arranged opposite to each other, and the opposite sides of the partition plate 2 are respectively inserted into the two side slots 1112.

[0066] By providing the top slot 1111 and the side slot 1112, the shaking of the partition plate 2 within the filter chamber 13 can be effectively limited, ensuring the installation stability and reliability of the partition plate 2 within the filter chamber 13. Simultaneously, the side slot 1112 facilitates guidance for the upper end of the partition plate 2 to be inserted into the top slot 1111, improving the assembly efficiency of the partition plate 2. In other embodiments, the mounting slot 111 may include only the side slot 1112 or only the top slot 1111.

[0067] In one embodiment, the side slots 1112 extend vertically downward through the filter cartridge 11, so that the separator plate 2 can be inserted into the two side slots 1112 through the lower opening of the filter cartridge 11, thereby further improving the assembly accuracy and assembly efficiency of the separator plate 2.

[0068] Furthermore, a reinforcing rib 15 is provided protruding on the cavity wall of the filter chamber 13. The reinforcing rib 15 is provided in a one-to-one correspondence with the side slot 1112. One side of the reinforcing rib 15 forms one side of the groove wall of the side slot 1112. This can improve the blocking effect of the groove wall of the side slot 1112 on the partition plate 2 while ensuring the local structural strength of the filter cylinder 11 at the side slot 1112.

[0069] In one embodiment, the vertical distance between the bottom of the top slot 1111 and the bottom of the filter chamber 13 is H, and the height of the partition plate 2 is h, where H > h. This ensures that during assembly, a gap exists between the upper end of the partition plate 2 and the bottom of the top slot 1111, and / or between the lower end of the partition plate 2 and the bottom of the filter chamber 13. This gap prevents the partition plate 2 from being unable to be assembled into the filter chamber 13 due to machining errors causing its height to exceed the design height, or due to machining errors in the condenser shell 100 causing the vertical distance to be less than the height of the partition plate 2. This better ensures the ease and reliability of partition plate 2 assembly. Furthermore, the vertical distance between the bottom of the top slot 1111 and the lower boss 123 is H.

[0070] Furthermore, 0.3mm≤Hh≤4mm, and the difference between H and h can be, but is not limited to, 0.3mm, 0.5mm, 0.8mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm and 4mm, etc.

[0071] like Figures 6 to 7 As shown, in one embodiment, the condenser housing 100 includes an elastic structure. The lower side of the elastic structure abuts against or is connected to the bottom of the filter chamber 13, and the upper side of the elastic structure abuts against the lower end of the partition plate 2. The elastic structure can deform in the vertical direction. This allows the upper end of the partition plate 2 to be stably inserted into the top slot 1111 by pressing against the lower end of the partition plate 2 through the elastic structure. Simultaneously, because the elastic structure can elastically deform in the vertical direction, even if the length of the partition plate 2 increases due to processing errors, the partition plate 2 can still be compressed by pressing against the elastic element, ensuring that the partition plate 2 is smoothly assembled into the filter chamber 13.

[0072] To simplify the structure, in one embodiment, the elastic structure includes the aforementioned annular seal 3, thereby integrating the sealing structure and the elastic structure into one unit, reducing the number of parts and simplifying assembly. Simultaneously, the annular arrangement of the elastic structure also helps ensure its integrity and reliability. In another embodiment, the elastic structure can be an elastic gasket, disposed inside the annular seal 3 and separate from it. In yet another embodiment, the elastic structure can also be a spring or other elastic structure.

[0073] Furthermore, the annular seal 3 includes a sealing ring portion 31 and a pressing ring portion 32 protruding from the upper side of the sealing ring portion 31. The sealing ring portion 31 is sandwiched between the bottom of the filter chamber 13 and the filter cartridge portion 11, and the pressing ring portion 32 is located inside the filter cartridge portion 11, with the lower end of the partition plate 2 abutting against the pressing ring portion 32. This arrangement ensures the sealing effect of the annular seal 3 while enhancing the deformation capacity at the point where the annular seal 3 presses against the partition plate 2, thereby further improving the reliability of the annular seal 3.

[0074] In one embodiment, the upper end of the pressing ring portion 32 is higher than the upper end of the lower boss portion 123 to avoid interference between the partition plate 2 and the lower boss portion 123.

[0075] Example 2

[0076] This embodiment provides a condensation heat exchange device, and the condensation heat exchange device provided in this embodiment has a basically the same structure as the condensation heat exchange device provided in Embodiment 1, with only some differences in the settings. This embodiment will not repeat the same content as in Embodiment 1.

[0077] like Figures 8 to 10 As shown, in this embodiment, a water passage hole 21 is provided at the lower end of the partition plate 2, and the elastic structure includes an elastic edging member 4 wrapped around the edge of the water passage hole 21 and the lower end of the partition plate 2. The elastic edging member 4 abuts against the bottom of the filter chamber 13.

[0078] By wrapping the elastic structure around the lower end of the partition plate 2 and the periphery of the water passage 21, the assembly stability and reliability of the elastic structure and the partition plate 2 can be guaranteed. At the same time, the edges of the partition plate 2 can be wrapped to prevent the edges of the partition plate 2 from scratching the operator when the operator assembles the partition plate 2, thereby improving the convenience and safety of assembly.

[0079] The elastic edge banding 4 includes a first edge banding portion 41 and two second edge banding portions 42 connected to both ends of the first edge banding portion 41. The shape of the first edge banding portion 41 is the same as the shape of the water passage hole 21. The second edge banding portions 42 extend in a direction away from the other second edge banding portion 42. The first edge banding portion 41 wraps around the edge of the water passage hole 21, and the second edge banding portion 42 wraps around the lower ends of the partition plate 2 on both sides.

[0080] In this embodiment, the water passage 21 is a U-shaped hole with the opening facing downwards, which can enhance the smoothness of water flow. In other embodiments, the water passage 21 can also be a C-shaped hole, a rectangular hole, an arc-shaped hole, or a hole of other shapes.

[0081] To improve the assembly stability of the elastic edging part 4 and the partition plate 2, an insertion groove 43 is provided on the upper side of the elastic edging part 4. The insertion groove 43 extends from one end of the second edging part 42 to the end of the other second edging part 42, and the partition plate 2 is inserted into the insertion groove 43.
