Description

Technical Field

[0001] This utility model belongs to the field of environmental protection equipment technology, and in particular relates to a combined hydrophobic expansion container. Background Technology

[0002] Currently, in industries such as power, petrochemicals, and chemicals, the recovery of high-temperature condensate is crucial for energy conservation, emission reduction, and cost savings. Typically, the high-temperature, high-pressure condensate is first introduced into a condensate expansion tank, where pressure reduction causes flash evaporation, separating a portion of the secondary steam for reuse. Subsequently, the remaining condensate is transported to a condensate tank for collection and storage, so that it can be pumped back to the boiler feedwater system or other thermal systems later.

[0003] In existing technologies, high-temperature return water discharged from the condensate expansion container is typically piped directly into the condensate tank. However, this seemingly simple process has some technical drawbacks. Because the pressure inside the condensate expansion container is usually higher than that in the condensate tank, and there is often a height difference between the two, the condensate has a very high flow rate and energy when it is discharged into the condensate tank.

[0004] When condensate from the condensate expansion tank is transferred to the condensate tank, the height difference between the two causes the condensate to violently impact the liquid surface or bottom of the condensate tank, generating a huge impact force that causes equipment vibration and impact noise. This not only affects the structural safety of the equipment and connected pipelines but also severely deteriorates the on-site working environment, making it a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] Details of one or more embodiments of the present invention are set forth in the following drawings and description to make other features, objects and advantages of the present application more readily apparent.

[0006] This invention proposes a combined hydrophobic expansion container, which, with the help of a flow guiding component, provides a channel for condensate entering the hydrophobic tank and slows down the flow rate of the water, thereby solving the problem of noise and vibration caused by condensate impacting the bottom of the hydrophobic tank when the hydrophobic expansion container delivers condensate to the hydrophobic tank.

[0007] This utility model discloses a combined hydrophobic expansion container, which has a water inlet, a drain outlet at the bottom, and a steam vent at the top. The condensate tank has a connecting port at the top, which connects to the drain outlet of the condensate expansion container to form a combined channel; the condensate tank also has an outlet at the bottom. A flow guiding structure is installed inside the drainage tank and below the connecting port; it is used to guide the liquid to flow smoothly from the connecting port into the bottom of the drainage tank.

[0008] In some embodiments, the flow guiding structure is a pipe located below the drain outlet, with its top end being an inverted cone shape that is wider at the top and narrower at the bottom, and its bottom end located near the water outlet.

[0009] In some embodiments, the combined hydrophobic expansion container further includes an anti-vortex structure disposed at the outlet to eliminate or reduce vortex phenomena at the outlet.

[0010] In some embodiments, the combined hydrophobic expansion container further includes: A level gauge is used to detect the liquid level inside a hydrophobic tank. The temperature detection module is used to detect the water temperature in the condensate tank.

[0011] In some embodiments, the bottom of the condensate tank is provided with an openable and closable drain outlet.

[0012] In some embodiments, the combined hydrophobic expansion tank further includes an overflow port disposed on the side wall of the hydrophobic tank, the height of which is used to limit the maximum normal operating liquid level of the hydrophobic tank.

[0013] In some embodiments, the combined hydrophobic expansion container further includes an inspection hole, with both the hydrophobic expansion container and the hydrophobic tank having an inspection hole for inspection of the interior of the hydrophobic expansion container and the hydrophobic tank.

[0014] In some embodiments, the horizontal length of the hydrophobic tank is greater than the height of the hydrophobic tank.

[0015] In some embodiments, the combined hydrophobic expansion container further includes: a mounting base, which has two mounting bases and is fixed to the bottom of the hydrophobic tank; one mounting base is fixed in position and the other can slide horizontally relative to the ground.

[0016] In some embodiments, the combined hydrophobic expansion container further includes: two annular reinforcing members; the two annular reinforcing members are fixed inside the hydrophobic tank and are arranged along the length of the hydrophobic tank, and correspond to the connection position of the mounting base; Each annular reinforcement has an impurity channel at its bottom and a liquid passage above the impurity channel; the two annular reinforcements divide the interior of the condensate tank into three areas, with the connecting port, outlet, and flow guiding structure all located between the two annular reinforcements.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model directly connects the condensate expansion container to the top of the condensate tank and sets a flow guiding component in the condensate tank. This allows the condensate entering the condensate tank to flow smoothly into the condensate tank along the flow guiding component when the condensate expansion container delivers condensate to the condensate tank. This solves the problem of noise and equipment vibration caused when condensate falls directly to the bottom of the condensate tank.

[0018] 2. This utility model can effectively eliminate the eddies generated when condensate is drained from the condensate tank by setting an anti-eddy structure at the outlet, thereby reducing the fluctuation inside the condensate tank caused by the eddies and avoiding vibration of the condensate tank.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments provided by this utility model without inventive effort are within the scope of protection of this utility model.

[0022] In the description of this utility model, it should be understood that the terms "center", "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] As attached Figure 1-8 As shown in the schematic embodiment of the combined hydrophobic expansion container of this utility model, the combined hydrophobic expansion container includes a hydrophobic expansion container 1, which has a water inlet 13, a drain outlet 11 at the bottom, and a steam vent 12 at the top; a hydrophobic tank 2, which has a connecting port 21 at the top, which is connected to the drain outlet 11 of the hydrophobic expansion container 1 to form a combined channel; a water outlet 22 at the bottom of the hydrophobic tank 2; and a flow guiding structure 3, which is disposed inside the hydrophobic tank 2 and located below the connecting port 21, to guide the liquid to flow smoothly into the bottom of the tank from the connecting port 21.

[0026] During operation, the hydrophobic expansion tank 1 has at least one inlet 13 on its side wall. The upstream equipment is connected to the inlet 13 of the hydrophobic expansion tank 1 via pipeline. A valve is installed at the inlet 13 to control the flow of high-temperature, high-pressure return water into the hydrophobic tank 2. A seal is installed at the inlet 13 to ensure a good seal. The inlet 13 typically employs a tangential feeding design, forming a vortex structure that causes the liquid to rotate within the inlet 13, accelerating vapor-liquid separation using centrifugal force and the vortex effect. Since the vortex structure used at the inlet 13 of the hydrophobic expansion tank 1 is a common design, it will not be elaborated upon further here.

[0027] After the steam trap is opened, the high-temperature and high-pressure return water from the upstream equipment enters the steam trap expansion container 1. The high-temperature return water undergoes flash evaporation in the steam trap expansion container 1, transforming into condensate and steam. The steam is discharged from the steam vent 12 of the steam trap expansion container 1, while the condensate enters the steam trap 2 through the drain outlet 11 and the connecting outlet 21 in sequence.

[0028] The condensate entering the condensate tank 2 falls into the guide inlet 31 below the connecting port 21, and enters the guide structure 3 through the guide inlet 31. Under the guidance of the guide structure 3, the condensate slowly flows downward into the bottom of the condensate tank 2.

[0029] Furthermore, the drainage outlet 32 ​​of the flow guiding structure 3 is located near the bottom of the condensate tank 2, so that condensate enters from below the liquid level to eliminate the impact of condensate on the liquid level.

[0030] This equipment reduces the footprint by placing the hydrophobic expansion container 1 above the hydrophobic tank 2, eliminating the need for a raised foundation for the hydrophobic expansion container 1.

[0031] Because the condensate diffuser 1 is positioned above the condensate tank 2, the height from which the condensate falls is increased, resulting in a greater impact on the bottom or bottom surface of the condensate tank 2. The design of the flow guiding structure 3 ensures that the condensate flows smoothly into the bottom of the condensate tank 2 after entering; this design avoids the impact on the bottom surface of the condensate tank 2 when water falls from a height, eliminating the noise and vibration caused by the impact of condensate falling from a height.

[0032] Furthermore, the condensate tank 2 can be equipped with multiple level gauges 24. If any level gauge 24 fails, the level can still be monitored through other level gauges 24 that are in normal working order.

[0033] Furthermore, the drain tank 2 has two connection ports 21, one for normal use and the other sealed with a blind cover. If the normal port fails, the connection can be switched to the backup port to ensure the normal operation of the equipment.

[0034] In some embodiments, the flow guiding structure 3 is a pipe located below the drain outlet 11 so that the condensate falling into the condensate tank 2 can accurately enter the flow guiding structure 3; its bottom end is located near the outlet 22 and below the liquid surface in the condensate tank 2 to reduce the impact of condensate on the bottom of the condensate tank 2, thereby reducing noise.

[0035] Furthermore, the top of the flow guiding structure 3 is an inverted cone shape that is wider at the top and narrower at the bottom. This design allows the flow guiding inlet 31 to receive all the water flow into the pipe when the water flows into the drainage tank 2. This allows the water to flow downward along the flow guiding structure 3 and into the bottom of the drainage tank 2, avoiding noise and vibration caused by the water flow impact due to the water flow falling directly into the bottom of the drainage tank 2.

[0036] Furthermore, the bottom of the flow guiding structure 3 discharges water in a horizontal direction to avoid causing fluctuations in the liquid level inside the drainage tank 2 or stirring up debris at the bottom of the drainage tank 2.

[0037] Furthermore, the flow guiding structure 3 has two flow guiding drain outlets 32, which are located on opposite sides of the two outlets 22. The two flow guiding drain outlets 32 discharge water in opposite horizontal directions, thereby reducing the possibility of water flow causing eddies at the two outlets 22, avoiding the increase of air content in the outlets 22 due to eddies, and reducing the possibility of cavitation in external equipment connected to the outlets 22.

[0038] Furthermore, the flow guiding structure 3 also includes at least one first support 33 and at least one second support 34. The first support 33 is disposed below the flow guiding structure 3, with its upper end fixedly connected to the bottom of the flow guiding structure 3, and its lower end firmly supported and fixed to the bottom inner wall of the drainage tank 2. At least one second support 34 is also provided on the top of the flow guiding structure 3, with one end of the second support 34 connected to the outer wall of the top of the flow guiding structure 3, and the other end fixedly connected to the inner wall of the drainage tank 2.

[0039] The combined use of the first bracket 33 and the second bracket 34 provides a fixed support for the flow guiding structure 3, which greatly enhances the structural stability of the flow guiding structure 3, thereby significantly improving the operational reliability and service life of the entire equipment.

[0040] In some embodiments, the combined hydrophobic expansion container also includes an anti-vortex structure 7 disposed at the outlet 22 to eliminate or reduce vortex phenomena at the outlet 22. An anti-vortex structure 7 is disposed at each outlet 22.

[0041] A water outlet 22 is provided at the bottom of the condensate tank 2 for connecting to an external condensate pump to transport the collected condensate to the subsequent system.

[0042] An anti-vortex structure 7 is installed at the inlet of the first outlet 22 inside the condensate tank 2. This device prevents the formation of vortices at the pump inlet, which would entrain gas into the pump and cause cavitation, thereby extending the service life of the condensate pump.

[0043] Specifically, the anti-vortex structure 7 includes a cover plate 71, which is circular and coaxially disposed above the inlet of the outlet 22; a first baffle 72, one end of which is fixedly connected to the side of the cover plate 71 facing the outlet 22; and a second baffle 73, one end of which is fixedly connected to the side surface of the cover plate 71, and the second baffle 73 is perpendicular to the first baffle 72.

[0044] Specifically, the cover plate 71 is a circular plate structure. A first baffle 72 and a second baffle 73 are fixedly connected to the side of the cover plate 71 facing the outlet 22. The first baffle 72 and the second baffle 73 coaxially mount the cover plate 71 directly above the outlet 22, maintaining a certain distance from it. This arrangement ensures that water can only flow radially into the outlet 22 from around the cover plate 71, thus initially disrupting the conditions for direct downward flow and the formation of vortices. The first baffle 72 and the second baffle 73 further eliminate any rotational tendency that might arise from radial flow.

[0045] This structural design forces the water flowing in from all sides through a cross-shaped channel formed by the first baffle 72 and the second baffle 73, effectively reducing the rotational speed of the water flow and causing it to flow into the outlet 22 approximately perpendicular to the baffles. This design completely eliminates the conditions for vortex formation, ensuring that the water is smoothly drawn into the condensate pump, thereby reliably preventing pump cavitation and greatly improving the pump's operational stability and service life.

[0046] In some embodiments, the combined hydrophobic expansion container also includes a level gauge 24 for detecting the liquid level inside the hydrophobic tank 2.

[0047] Furthermore, the level gauge 24 can be viewed locally on-site, or it can be transmitted remotely to the control system to set high and low water level thresholds, and to control the start and stop of the water pump connected to the condensate inlet 13.

[0048] Furthermore, the level gauge 24 can be a magnetic float level gauge; the magnetic float level gauge detects the liquid level height through the buoyancy principle of an electromechanical float. Magnetic float level gauges are simple to operate and easy to install, and have visualization and alarm functions, but their accuracy is relatively low.

[0049] Furthermore, multiple level gauges 24 are provided to prevent the level gauge 24 from malfunctioning and failing to monitor the liquid level.

[0050] Furthermore, the combined hydrophobic expansion container temperature detection module 26 is used to detect the water temperature of the hydrophobic tank 2.

[0051] The temperature inside the hydrophobic tank 2 can be clearly monitored by the detection results of the temperature detection module 26, ensuring that the internal temperature meets the usage requirements.

[0052] In some embodiments, the bottom of the condensate tank 2 is provided with an openable and closable drain port 25 to discharge impurities deposited at the bottom of the condensate tank 2. A valve is provided on the outside of the drain port 25, and the drain port 25 is opened and closed by opening and closing the valve.

[0053] Furthermore, the condensate tank 2 can be equipped with a sampling valve. By analyzing the sample taken out by the sampling valve, the situation of impurity deposition at the bottom of the condensate tank 2 can be understood, and the condensate tank 2 can be drained through the drain outlet 25.

[0054] Furthermore, the sampling valve is coupled into the level gauge 24.

[0055] In some embodiments, the combined hydrophobic expansion container also includes an overflow port 23 disposed on the side wall of the hydrophobic tank 2, the height of which is used to limit the maximum normal operating liquid level of the hydrophobic tank 2.

[0056] An overflow port 23 is provided on the side wall of the condensate tank 2. The height of the overflow port 23 is pre-designed to limit the maximum normal operating liquid level of the condensate tank 2. When the incoming water volume increases, causing the liquid level to exceed the preset height, the excess water will be automatically discharged through the overflow port 23. This not only prevents the condensate tank 2 from becoming too full, but also ensures that the interior of the condensate expansion container 1 always maintains sufficient working space, preventing water from flowing back into the condensate expansion container 1 due to the condensate tank 2 becoming too full, thus preventing the condensate expansion container 1 from losing its expansion function. This plays an important safety protection role.

[0057] In some embodiments, the combined hydrophobic expansion container further includes an inspection hole 5. Both the hydrophobic expansion container 1 and the hydrophobic tank 2 are provided with inspection holes 5 for inspection of the interior of the hydrophobic expansion container 1 and the hydrophobic tank 2.

[0058] Specifically, the condensate drain 1 is equipped with an openable and closable inspection port 5 to allow maintenance personnel to inspect and maintain its internal structure. The condensate tank 2 is also equipped with an openable and closable inspection port 5 at its end to allow maintenance personnel to inspect and maintain its internal flow guiding structure 3 and anti-vortex structure 7. A sealing structure is provided at the inspection port 5 to ensure a tight seal when closed.

[0059] In some embodiments, the horizontal length of the condensate tank 2 is greater than its height, resulting in a lower center of gravity and better resistance to overturning.

[0060] Furthermore, an inspection hole 5 is provided at each end of the condensate tank 2.

[0061] Furthermore, the condensate tank 2 can be a horizontal elongated cylindrical shape to reduce the impact of the liquid inside the condensate tank 2 on its ends, thereby extending its service life. Similarly, designing the condensate tank 2 as a horizontal elongated cylindrical structure increases its pressure-bearing capacity.

[0062] In some embodiments, the combined hydrophobic expansion container also includes a mounting base 4, which is provided in two and fixed to the bottom of the hydrophobic tank 2; one mounting base 4 is fixed in position, and the other can slide horizontally relative to the ground.

[0063] Two mounting bases 4 are fixed at the bottom of the drainage tank 2. The mounting base 4 includes an arc-shaped plate 41 that fits and is fixed to the outer contour of the drainage tank 2, and a support part 42 that is fixedly connected to the arc-shaped plate 41 at one end. The other end of the support part 42 is provided with a mounting plate 43, and the mounting plate 43 has a mounting hole for fixing the mounting base 4 in a preset position by inserting fasteners.

[0064] Furthermore, the fixed mounting base 4 has a circular hole 431 at its bottom, through which anchor bolts pass to fix it to the ground. Another mounting base 4, which can slide horizontally relative to the ground, has an elongated hole 432 at its bottom parallel to the axis of the condensate tank 2, through which anchor bolts pass to connect it to the ground. This design accommodates dimensional deviations during installation or spacing changes due to thermal expansion and contraction during operation, ensuring the condensate tank 2 remains stable and guaranteeing the safety and reliability of the equipment structure.

[0065] Furthermore, four support legs 6 are provided at the bottom of the drainage expansion container 1, and each support leg 6 has a pad 61 at both ends. One pad 61 should fit snugly against the side wall of the drainage expansion container 1, and the other pad 61 should fit snugly against the side wall of the drainage tank 2. During installation, the support legs 6 are fixedly connected to the bottom of the drainage expansion container 1 and the top of the drainage tank 2 in preset positions by bolting or welding. The support legs 6 effectively distribute the weight of the drainage expansion container 1, preventing the connecting parts from being damaged by excessive pressure over a long period of time, and enhancing the overall structural stability of the equipment.

[0066] In some embodiments, the combined hydrophobic expansion container further includes two annular reinforcing members 8; the two annular reinforcing members 8 are fixed inside the hydrophobic tank 2 and are arranged along the length of the hydrophobic tank 2, corresponding to the connection position of the mounting base 4; each annular reinforcing member 8 has an impurity channel 81 at its bottom and a liquid through hole 82 above the impurity channel 81; the two annular reinforcing members 8 divide the interior of the hydrophobic tank 2 into three areas, with the connecting port 21, the outlet 22, and the flow guiding structure 3 all located between the two annular reinforcing members 8. The reinforcing members 8 can effectively improve the pressure-bearing capacity of the hydrophobic tank 2 shell and enhance the rigidity and stability of the overall structure of the hydrophobic tank 2.

[0067] Two reinforcing members 8 are installed inside the condensate tank 2 to ensure the strength of the connection. These two reinforcing members 8 are respectively installed in the positions of the two mounting bases 4. The reinforcing members 8 are fixedly connected to the inner wall of the condensate tank 2 by welding or other connection methods.

[0068] Furthermore, the reinforcing member 8 includes an outer ring 83 and an inner ring 84. The outer ring 83 is fixedly connected to the inner wall of the drainage tank 2, and the outer side of the inner ring 84 is fixedly connected to the inner side of the outer ring 83. The liquid passage 82 is located inside the inner ring 84, and the impurity passage 81 is located at the bottom of the outer ring 83. The axial width of the inner ring 84 is greater than the axial width of the outer ring 83. The difference in axial width between the outer ring 83 and the inner ring 84 can further improve the stabilizing effect of the reinforcing member on the water level in the drainage tank 2.

[0069] Through the description of several embodiments of the subject matter of this utility model, it can be seen that the embodiments of the combined hydrophobic expansion container of this utility model have at least one or more of the following advantages: 1. This utility model directly connects the condensate expansion container to the top of the condensate tank and sets a flow guiding component in the condensate tank. This allows the condensate entering the condensate tank to flow smoothly into the condensate tank along the flow guiding component when the condensate expansion container delivers condensate to the condensate tank. This solves the problem of noise and equipment vibration caused when condensate falls directly to the bottom of the condensate tank.

[0070] 2. This utility model can effectively eliminate the eddies generated when condensate is drained from the condensate tank by setting an anti-eddy structure at the outlet, thereby reducing the fluctuation inside the condensate tank caused by the eddies and avoiding vibration of the condensate tank.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
