Specifically, it relates to an aeration system for underground sewage treatment, and more specifically to an automatic condensate discharge device and a corresponding aeration system capable of automatically discharging condensate. Background Technology
[0002] An aeration system accelerates the transfer of oxygen from the air to the wastewater by agitating it with aeration equipment, thereby increasing the oxygen content in the wastewater and oxidizing and decomposing organic matter. Therefore, aeration is one of the main methods in water treatment and an effective measure to improve the quality and efficiency of water treatment.
[0003] Most existing aeration systems are fixed to the bottom of the tank using matching pipes and supports. Air is supplied to the aeration system via a blower or compressed air unit. With prolonged continuous operation, condensate formed when the air fed into the pipes cools accumulates inside, increasing pressure loss and consequently affecting the aeration effect.
[0004] Therefore, a reliable measure is needed to promptly drain condensate from the aeration system, reducing pressure loss caused by prolonged operation and improving the system's performance. More importantly, this reliable measure should be as energy-efficient, easy to maintain, and convenient to manage as possible. Utility Model Content

[0033] In the following detailed description of the embodiments, the same reference numerals in the drawings denote components with the same or the same function.
[0034] As described above, this invention proposes a device capable of reliably and promptly draining condensate from an aeration system. To address the aforementioned problems in the prior art, the automatic condensate drainage device of this invention utilizes the siphon effect. Through the structure proposed in the embodiments of this invention, fully automatic drainage is achieved when condensate accumulates to a certain amount within the aeration system. Furthermore, this automatic condensate drainage device requires no manual operation or additional energy consumption. While ensuring timely and effective condensate drainage, it reduces labor and electricity costs, is easy to maintain and manage, and thus reduces pressure loss during long-term operation, contributing to improved aeration system performance.
[0035] Figure 1 A schematic diagram of an automatic condensate drain device 100 according to the present invention is shown. Figure 1 As shown, the automatic condensate drain device 100 is installed in the aeration pipe 220 of the aeration system to drain liquid (not shown) from the aeration pipe 220. For this purpose, the automatic condensate drain device 100 includes a drain pipe 110 inserted into the aeration pipe 220. The drain pipe 110 is transverse to the aeration pipe 220 and extends to the bottom of the aeration pipe 220. The transverse orientation of the drain pipe 110 to the aeration pipe 220 means that the extension direction of the drain pipe is not parallel to the extension direction of the aeration pipe, but forms an angle with it. Preferably, the drain pipe 110 extends perpendicular to the aeration pipe 220, i.e., the extension direction of the drain pipe forms a 90° angle with the extension direction of the aeration pipe. The drain pipe is preferably, for example, a plastic pipe, which may have a specification such as De25-50.
[0036] A drain outlet 111 is constructed at the lower end of the drain pipe 110, particularly on the lower end face of the drain pipe 110. In a preferred embodiment, in order to ensure that the condensate is discharged as completely as possible, the drain outlet 111 should be as close as possible to the bottom of the aeration pipe 220.
[0037] In addition, such as Figure 1 As shown, a vent hole 112 is provided on the side wall of the drain pipe 110. It is important to note that the vent hole 112 is positioned so that it is located inside the aeration pipe 220 when the drain pipe 110 is inserted into the aeration pipe 220. Therefore, the vent hole 112 is configured such that the distance between it and the inner wall of the bottom of the aeration pipe 220 is less than the inner diameter of the aeration pipe 220.
[0038] Figure 2 A schematic diagram illustrating the function of an embodiment of the automatic condensate drainage device 100 according to the present invention is shown. As the aeration system operates continuously for an extended period, condensate is generated after the air supplied to the aeration pipe 220 is cooled, and it accumulates within the aeration pipe 220. For example... Figure 2The condensate level is schematically shown with a thicker straight line. Due to the continuous flow of air in the aeration pipe 220, some air accelerates through the vent 112. When the condensate level submerges the drain outlet 111, the accelerated air flow creates a negative pressure in the area below the vent 112 in the drain pipe 110 (e.g., shown by the dashed box). Subsequently, the condensate accumulated at the bottom of the aeration pipe 220 is forced into the drain pipe 110 by the negative pressure in the drain pipe 110 and the normal air pressure in the aeration pipe 220, and is thus discharged from the aeration pipe 220 along the drain pipe 110 (as shown by the dashed arrow). Thus, the automatic condensate discharge device 100 according to this invention achieves real-time monitoring and automatic discharge of condensate, without manual operation or additional energy consumption.
[0039] In a preferred embodiment of the automatic condensate drain device 100 according to the present invention, the drain outlet 111 is constructed as a beveled cut relative to the drain pipe 10. In this case, the vent 112 is constructed such that the distance between it and the inner wall of the bottom of the aeration pipe 220 is less than the inner diameter of the aeration pipe 220, and is also constructed on the side wall above the upper end of the beveled cut. Thus, when the drain pipe 110 is inserted into the aeration pipe 220, the vent 112 is located inside the aeration pipe 220 and above the drain outlet 111, which is constructed as a beveled cut. In this case, to ensure that the condensate is drained as completely as possible, preferably, the lower end of the beveled cut abuts against the inner wall of the bottom of the aeration pipe 220.
[0040] In the above embodiments, in the initial stage of condensate accumulation, for example when the liquid level is still... Figure 2 When the position shown is below, a negative pressure zone has not yet formed in the area within the drain pipe 110 below the vent 112 and above the upper end of the bevel. However, once the drain outlet 111, constructed in the form of a bevel, is completely submerged (as shown...), a negative pressure zone is formed. Figure 2 As shown in the diagram, this creates negative pressure, which in turn triggers the discharge of condensate. In this case, depending on requirements, such as the tolerance for pressure loss, the trigger for condensate discharge can be adjusted by changing the bevel cut.
[0041] Therefore, in a preferred embodiment of the automatic condensate drain device 100 according to the present invention, the bevel is configured at an angle between 0° and 70° to the extending direction of the drain pipe 110. As the angle increases or decreases, the amount of condensate accumulated when the bevel is completely submerged also decreases or increases accordingly.
[0042] In a further embodiment, preferably, the vent 112 is located in the upper section of the drain pipe 111. This creates sufficient negative pressure in the area within the drain pipe 110 below the vent 112 and above the drain outlet 111 when the outlet 111 is completely submerged. Alternatively, the vent 112 may be constructed within the more preferably the upper third of the section of the drain pipe 110 located within the aeration conduit 220.
[0043] In addition, in order to create sufficient negative pressure, the diameter of the vent 112 is preferably 1 mm to 10 mm.
[0044] Furthermore, in some embodiments of the automatic condensate drain device 100 according to the present invention, such as Figure 1 and Figure 2 As shown, the automatic condensate drain device 100 also includes a drain connector 120, for example, in the form of a double-socket connector. The upper end of the drain pipe 110 is fluidly connected to the automatic drain device 230 through the drain connector 120. Preferably, the drain connector 120 is made of stainless steel. Thus, when the condensate level submerges the drain outlet 111, the condensate accumulated at the bottom of the aeration pipe 220 is forced from the aeration pipe 220 into the drain pipe 110 under the action of the negative pressure in the drain pipe 110 and the normal air pressure in the aeration pipe 220. This causes the condensate to be discharged from the aeration pipe 220 along the drain pipe 110 (as shown by the dashed arrow) and into the automatic drain device 230. Subsequently, the condensate is discharged from the entire aeration system via the automatic drain device 230.
[0045] Preferably, the automatic drainage device 230 is configured as an aeration disc. Thus, condensate is discharged from the entire aeration system via the aeration disc, particularly via the micropores of the aeration disc. Furthermore, besides the aeration disc, the automatic drainage device can also be configured in other forms capable of performing the drainage function.
[0046] In some embodiments of the automatic condensate drain device 100 according to this utility model, the drain connector 120 is inserted into and fixedly connected to the aeration pipe 220. Preferably, the drain connector 120 is directly welded to the aeration pipe 220 after being inserted into it. Furthermore, the drain connector 120, for example, in the form of a double-socket connector, is inserted into and fixedly connected to the aeration pipe 220 on one hand, and on the other hand, is connected to the automatic drain device 230, such as an aeration disc, in an airtight manner via a threaded connection. During installation, it is necessary to ensure that the threaded connection between the automatic drain device 230 and the drain connector 120 is tightened securely. Preferably, the drain connector 120 has an internal thread, and the automatic drain device 230 is screwed into the internal thread of the drain connector 120.
[0047] Figure 3A schematic cross-sectional view of an embodiment of an aeration system 200 according to the present invention is shown, in which an automatic condensate discharge device 100 according to the present invention is installed.
[0048] like Figure 3 As shown, the aeration system 200 according to this invention is used in a tank 300, which includes a bottom 310 and a wall 320, wherein a liquid to be treated, such as wastewater, is conveyed into the tank 300. Generally, the aeration system 200 includes at least an air inlet riser 210, aeration pipes 220, aeration discs or other types of aeration components, and an adjusting support. An air source is provided to the aeration system by a blower or compressed air compressor. The air supplied by the air source is conveyed along the air inlet riser 210, which extends substantially along the tank wall 320, to the aeration pipes 220 distributed at the bottom 310. A corresponding number of aeration discs or other types of aeration components (not all shown for simplicity) are installed on the aeration pipes 220 according to aeration needs and / or actual requirements. The pipes of the aeration system 200, such as the air inlet riser 210 and aeration pipes 220, are supported and fixed to the tank body 300, such as the tank bottom 310 or the tank wall 320, by adjusting brackets (not shown for simplicity). The adjusting brackets can accommodate pipes of different specifications, such as the air inlet riser 210 and the aeration pipes 220, as well as tank bodies 300 with different structures, such as the tank bottom 310 or the tank wall 320. Furthermore, the adjusting brackets are preferably made of stainless steel.
[0049] To address the problem in existing technologies where condensate gradually accumulates in the pipes during aeration system operation, leading to increased pressure loss and affecting aeration efficiency, the aeration system 200 according to this invention further incorporates the aforementioned automatic condensate drainage device 100. Specifically, in the aeration system 200, the automatic condensate drainage device 100 is installed at the location of the automatic drainage device 230 in the aeration pipe 220. Therefore, according to this invention, the aeration system 200 further includes a connection opening 222 in the aeration pipe through which the automatic condensate drainage device 100, and particularly its drain pipe 110, passes. Simultaneously, the automatic drainage device 230, located at the connection opening 222, is connected to the automatic condensate drainage device 100, and particularly to the drain connector 120 of the automatic condensate drainage device 100. Thus, the liquid, especially condensate, in the aeration pipe 220 is discharged from the aeration system 200 along the drain pipe 110 via the automatic drainage device 230 at the connection opening 222.
[0050] In a further preferred embodiment of the aeration system 200 according to the present invention, an automatic condensate discharge device 100 is installed in the tail end area of the aeration pipe 220, such as... Figure 3 and Figure 4 As shown. However, the automatic condensate drain device 100 is not limited to being installed at this location, and more than one automatic condensate drain device can be arranged in each aeration system 200.
[0051] Furthermore, in a preferred embodiment of the aeration system 200 according to the present invention, the aeration pipe 220 of the aeration system 200 has a saddle (not shown) for mounting the aeration disc 230 or other types of aeration components and / or the automatic drainage device 230 of the automatic condensate drain device 100. Here, the saddle for mounting the automatic condensate drain device 100 is arranged at the connection opening 222, and the drain pipe of the automatic condensate drain device 100 (if necessary, together with the drain connector 120) passes through the saddle in an airtight seal. The saddle is preferably made of rubber material, or other materials that can ensure airtight sealing performance may be used if necessary.
[0052] The aeration system of this invention can automatically discharge condensate when it accumulates to a certain amount, without requiring manual operation or additional energy consumption. Therefore, the automatic condensate discharge device of this invention can promptly empty the condensate from the aeration system, preventing malfunctions. In summary, the aeration system of this invention and the automatic condensate discharge device installed within it not only reduce labor and electricity costs but also facilitate maintenance and management, thus reducing pressure loss during long-term operation and improving the overall performance of the aeration system.
[0053] The above are exemplary embodiments disclosed in this utility model. However, it should be noted that various changes and modifications can be made without departing from the scope of the embodiments disclosed in this utility model. Furthermore, although the elements disclosed in the embodiments of this utility model may be described or claimed individually, they may be understood as multiple unless explicitly limited to a singular number.
