[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1 to 9 As shown, a heat recovery coil condensate recovery device includes a top-open water collection tank 1. A partition 16 is installed inside the water collection tank 1, dividing the internal space of the water collection tank 1 into two independent upper and lower spaces. The water collection tank 1 also has an inlet 11 located above the partition 16 and a outlet 12 located below the partition 16. It also includes a vertically extending pre-filter pipe 21, one end of which is connected to the inlet 11, and the other end of which is provided with a debris collection pipe 3. The outlet 12 is connected to the pre-filter pipe 21 via a post-filter pipe 22. A filter screen 31 is installed on the debris collection pipe 3 near the filter openings of the pre-filter pipe 21 and the post-filter pipe 22.

[0032] Working principle: the heat recovery coil 51 and the fin 52 attached to the outside of the heat recovery coil 51 are erected on the top of the water collecting tank 1. The traditional heat recovery coil 51 and fin 52 are generally installed in an integrated form by the container rack plate 53. The two sides of the heat recovery coil 51 and the fin 52 are open to form an air duct, which ensures ventilation and heat exchange. The bottom is open to avoid water accumulation. Therefore, after the heat recovery coil 51 and the fin 52 are erected on the top of the water collecting tank 1, in summer, when heat exchange and refrigeration are carried out, a large amount of condensate water will be formed around the heat recovery coil 51 on the fresh air side due to the sudden drop in temperature, and the falling condensate water will enter the inside of the water collecting tank 1. The condensate water first enters the space above the partition plate 16 in the water collecting tank 1, and then enters the pre-filter pipe 21 through the water inlet 11. The condensate water enters the pre-filter pipe 21 at the same time, and also enters the debris collection pipe 3. The condensate water enters the post-filter pipe 22 through the filter screen 31 after entering the debris collection pipe 3. Finally, the condensate water is filtered and enters the space below the partition plate 16 in the water collecting tank 1 through the water outlet 12 and is stored. The stored condensate water can be processed for other purposes in the later stage, for example, the condensate water is pressurized and atomized and sprayed to the heat recovery coil on the exhaust air side, which can further cool the heat recovery coil on the exhaust air side and improve the refrigeration recovery effect in summer.

[0033] As shown in Figures 5 to 9 , the water outlet 12 is located below the partition plate 16 and close to the partition plate 16, which can increase the water storage capacity of the water collecting tank 1 as much as possible.

[0034] Further, the water collecting tank 1 is also provided with an overflow outlet 13, and the height of the overflow outlet 13 is preferably consistent with the height of the water outlet 12, which is also to ensure the maximum water storage capacity.

[0035] The overflow outlet 13 is connected with an overflow pipe 4, which can be connected to an external water treatment system, such as a sewer drain pipe, to prevent excessive condensate water from overflowing.

[0036] In this embodiment, the pre-filter pipe 21 and the debris collection pipe 3 are fixedly connected by flanges. The bottom of the pre-filter pipe 21 is provided with a first flange plate 23, and the bottom of the debris collection pipe 3 is provided with a second flange plate 32. The debris collection pipe 3 is inserted into the inside of the pre-filter pipe 21 from the bottom of the pre-filter pipe 21 and is fixedly connected by the first flange plate 23 and the second flange plate 32. It should be noted that a sealing gasket needs to be added when the first flange plate 23 and the second flange plate 32 are connected to ensure the sealing property and prevent water leakage.

[0037] As shown in Figure 5 , Figure 8 and Figure 9As shown, the sundry collecting pipe 3 is open to one side of the connecting end of the post-filter pipe 22 and the pre-filter pipe 21 and is embedded with a filter screen 31. In this way, the condensed water enters the post-filter pipe 22 after being filtered by the filter screen 31, and the filtered sundries are accumulated inside the sundry collecting pipe 3. When the filtered sundries need to be cleaned, the sundry collecting pipe 3 can be taken out from the outside of the water collecting tank 1 for cleaning.

[0038] Further, the top of the partition plate 16 is provided with an obliquely arranged flow guide plate 14 for guiding the condensed water to flow to the upper water inlet 11.

[0039] In particular, in the embodiment, the inner wall of the water collecting tank 1 is provided with a support frame 15, and the heat recovery coil pipe 51 and the fin 52 are arranged on the top of the support frame 15 through a mounting frame plate 53.

[0040] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the involved claims.
