Description

Technical Field

[0001] The present application relates to the field of pipelines, and more particularly, to a dew condensation prevention device and a control method for the dew condensation prevention device. Background Art

[0002] A pipeline system is an overall system of pipelines and their related facilities for transporting fluids (such as water, gas, oil, chemicals, etc.). Pipeline systems are widely used in industries, agriculture, urban water supply, sewage treatment, oil and gas transportation, etc. Pipeline systems play an important role in modern society, ensuring the efficient transportation and utilization of resources.

[0003] When the temperature of the medium transported by the pipeline is relatively low, the temperature of the related components in the pipeline system is also relatively low. When the ambient temperature is relatively high, water vapor in the air will condense when it meets the cold, that is, dew condensation occurs in multiple parts of the pipeline system. When the pipeline system has important electrical components, it will cause corrosion or even leakage problems of the electrical components. Summary of the Invention

[0004] The object of the present invention is to at least solve the problem of corrosion or even leakage that dew may cause to the pipeline system. This object is achieved by the following technical solutions:

[0005] A first aspect of the present invention provides a dew condensation prevention device. The dew condensation prevention device includes a sensing module, a heating component, a control module, and a power supply module. The sensing module includes a temperature sensor and a humidity sensor. The temperature sensor is used to detect the temperature of the area where the part to be protected is located, and the humidity sensor is used to detect the humidity of the area where the part to be protected is located. The heating component is used to heat the area where the part to be protected is located. The temperature sensor and the humidity sensor are both connected to the control module. The control module is configured to judge whether the temperature reaches a preset temperature and whether the humidity reaches a preset humidity, so as to obtain the switch information of the heating component. The control module and the heating component are both connected to the power supply module. The power supply module is configured to control the opening and closing of the heating component according to the switch information of the heating component.

[0006] The dew condensation prevention device of this embodiment detects whether the temperature and humidity of the area where the part to be protected is located reach preset conditions by setting a temperature sensor and a humidity sensor. If the preset conditions are reached, the heating component is controlled to be turned on to increase the temperature of the surface of the part to be protected, thereby increasing the evaporation amount of the moisture on the surface of the part to be protected, reducing the volume of dew on the part to be protected, and also reducing the problems of corrosion or even leakage and short circuit that dew may cause to the electrical components of the part to be protected. Moreover, the heating component also reduces the humidity of the area where the part to be protected is located.

[0007] In addition, the anti-dew condensation device according to the present invention may also have the following additional technical features:

[0008] In some embodiments of the present invention, the heating assembly includes a heat generating element and a fan, and the fan is used to blow the heat generated by the heat generating element toward the part to be protected.

[0009] In the above technical solution, the heating component is configured to include a heat generating component and a fan, and the fan can transfer the heat generated by the heat generating component to the part to be protected in a timely manner, thereby increasing the evaporation rate and amount of water on the surface of the part to be protected.

[0010] In some embodiments of the present invention, the heat generating element comprises a resistance wire.

[0011] In the above technical solution, the heat generating element is set as a resistance wire, which can reduce costs.

[0012] In some embodiments of the present invention, the heating assembly also includes a box body, the heat generating element and the fan are located in the box body, the box body is provided with a first air outlet on a side facing the part to be protected, the heat generating element and the first air outlet are spaced apart along a first direction, and the fan is arranged on a side of the heat generating element away from the first air outlet.

[0013] In the above technical solution, the heating component is configured to include a box body, and the first air outlet is configured to face the part to be protected. In this way, the heat can be effectively blown to the part to be protected, thereby improving the utilization rate of the heat.

[0014] In some embodiments of the present invention, the heat generating element is disposed around the box body along the circumference of the box body, and is surrounded to form a channel for the airflow generated by the fan to pass through, and the channel is connected to the first air outlet.

[0015] In the above technical solution, the heat-generating component is arranged to be surrounded on the inner side of the box body and to form a channel. The airflow generated by the fan can be directly blown to the first air outlet through the channel and carry the heat generated by the heat-generating component. Therefore, more moisture on the surface of the protected part can be evaporated, thereby increasing the moisture evaporation rate and further reducing the corrosion or even short circuit problem that the moisture may cause to the protected part.

[0016] In some embodiments of the present invention, there are multiple heat generating parts, and the multiple heat generating parts are arranged in sequence along the first direction. The channels formed by the multiple heat generating parts are connected in the direction where the fan points to the heat generating parts, and the cross-sectional area in the first direction gradually decreases.

[0017] In the above technical solution, the airflow of the fan can take away the heat of multiple heat-generating parts when passing through multiple channels, and has little effect on the size of the airflow of the fan. Therefore, the temperature of the airflow blown out from the first air outlet can be increased, thereby further increasing the temperature of the part to be protected and increasing the evaporation rate of water.

[0018] In some embodiments of the present invention, there are multiple heat generating parts, and the multiple heat generating parts are arranged in sequence along the first direction. The channels formed by the multiple heat generating parts are connected in the direction where the fan points to the heat generating parts, and the part of the box body located between two adjacent heat generating parts is provided with a second air outlet.

[0019] In the above technical solution, a second air outlet is arranged between two adjacent heat-generating parts. In this way, part of the wind flow comes out from the second air outlet, thereby increasing the temperature of the area where the part to be protected is located and reducing the humidity of the area where the part to be protected is located, thereby delaying the condensation time of the part to be protected after the heating component stops working.

[0020] In some embodiments of the present invention, along the direction in which the fan points toward the heat-generating part, the wall of the box body provided with the second air outlet is inclined toward the interior of the box body, and the projection of the channel adjacent to the second air outlet and located on the side of the second air outlet away from the first air outlet along the first direction on the second air outlet covers at least part of the second air outlet.

[0021] In the above technical solution, the airflow in the channel can flow to the second air outlet as much as possible, further increasing the air volume of the second air outlet, that is, further increasing the temperature of the area where the protected part is located and reducing the humidity of the area where the protected part is located.

[0022] In some embodiments of the present invention, the heat generating element comprises a heating net extending from the inner surface of the box body to the central area of the box body, and the heating net is arranged to form the channel.

[0023] In the above technical solution, the heat generating element is arranged as a heating net, which has a large heat generating capacity and can provide a relatively high temperature for the channel even if it is arranged in a surrounding manner.

[0024] The second aspect of the present invention proposes a control method for an anti-condensation device, which is applied to the above-mentioned anti-condensation device, and the control method includes: obtaining temperature data detected by the temperature sensor and humidity data detected by the humidity sensor; judging whether the temperature data reaches a preset temperature and whether the humidity data reaches a preset humidity, and obtaining the switch information of the heating component, and sending a start signal of the heating component to the power supply module; the power supply module controls the heating component to be turned on for a preset time.

[0025] In some embodiments of the present invention, the control method further includes: during the period when the power supply module controls the heating component to be turned on for a preset duration, the temperature sensor and the humidity sensor stop working.

[0026] In the above technical solution, the working duration of the temperature sensor and the humidity sensor can be reduced, and their service life can be prolonged. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The exemplary implementation manners of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the exemplary implementation manners of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the implementation manners set forth herein. On the contrary, these implementation manners are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully communicated to those skilled in the art.

[0041] It should be understood that the terms used herein are for the purpose of describing specific exemplary implementation manners only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" as used herein may also include the plural forms. The terms "comprising", "including", "containing" and "having" are inclusive and thus specify the presence of the stated features, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the particular order described or illustrated, unless the order of performance is explicitly stated. It should also be understood that additional or alternative steps may be used.

[0042] Although the terms first, second, third, etc. may be used herein to describe multiple elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or section from another region, layer, or section. Unless the context clearly indicates otherwise, terms such as "first", "second", and other numerical terms do not imply an order or sequence when used herein. Thus, the first element, component, region, layer, or section discussed below may be referred to as the second element, component, region, layer, or section without departing from the teachings of the exemplary implementation manners.

[0043] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "coupled", "attached" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0044] For ease of description, spatial relative relation terms may be used in the text to describe the relationship of one element or feature shown in the figure with respect to another element or feature. These relative relation terms are, for example, "inner", "outer", "inner side", "outer side", "below", "beneath", "above", "over", etc. Such spatial relative relation terms are intended to include different orientations of the device in use or operation other than the orientations depicted in the figure. For example, if the device in the figure is flipped, an element described as "below" or "beneath" another element or feature will then be oriented as "above" or "over" the other element or feature. Therefore, the exemplary term "below" can include both the upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative relation descriptors used in the text are accordingly interpreted.

[0045] Figure 1 FIG. schematically shows a structural schematic diagram of a dew condensation prevention device according to an embodiment of the present invention.

[0046] As Figure 1 shown, according to an embodiment of the present invention, a dew condensation prevention device 100 is provided. The dew condensation prevention device 100 includes a sensing module 1, a heating component 2, a control module 3, and a power supply module 4. The sensing module 1 includes a temperature sensor 11 and a humidity sensor 12. The temperature sensor 11 is used to detect the temperature of the area where the part to be protected 200 is located, and the humidity sensor 12 is used to detect the humidity of the area where the part to be protected 200 is located. The heating component 2 is used to heat the area where the part to be protected 200 is located. The temperature sensor 11 and the humidity sensor 12 are both connected to the control module 3. The control module 3 is configured to determine whether the temperature reaches a preset temperature and whether the humidity reaches a preset humidity, and then obtain the switch information of the heating component 2. The control module 3 and the heating component 2 are both connected to the power supply module 4. The power supply module 4 is configured to control the on and off of the heating component 2 according to the switch information of the heating component 2.

[0047] The part to be protected 200 in this embodiment may be an important part in a pipeline system for transporting liquids or gases. When the temperature of the medium transported by the pipeline system is relatively low and the surrounding ambient temperature is relatively high, water vapor in the air will condense on the important part when it meets cold. When the dew drops fall on the electrical components of the important part, it may cause problems such as corrosion and even leakage and short circuit of the electrical components.

[0048] The heating component 2 in this embodiment plays a heating role. It may be an air-conditioning structure, and the air-conditioning structure can achieve heating of the part to be protected 200, or it may be an infrared heater, etc.

[0049] The temperature sensor 11 and the humidity sensor 12 in this embodiment can be integrated or separately provided. Optionally, the temperature sensor 11 and the humidity sensor 12 are integrated together.

[0050] Specifically, when the temperature sensor 11 detects that the temperature in the area where the part to be protected 200 is located reaches the preset temperature and the humidity sensor 12 detects that the humidity in the area where the part to be protected 200 is located reaches the preset humidity, the control module 3 then obtains the signal to turn on the heating component 2 and feeds it back to the power supply module 4. The power supply module 4 supplies power to the heating component 2, and the heating component 2 provides heat to the area where the part to be protected 200 is located, thereby increasing the temperature of the part to be protected 200, reducing the humidity in the area where the part to be protected 200 is located, reducing the volume of dew on the part to be protected 200, and thus reducing the possible corrosion or even short - circuit problems caused by dew to the part to be protected 200. Among them, the preset temperature and the preset humidity are determined according to the actual environment and specific needs. They can be the temperature and humidity conditions required for the part to be protected 200 to condense. Of course, the preset temperature and the preset humidity can also be lower than the temperature and humidity required for condensation.

[0051] Exemplarily, the power supply module 4 can be an uninterruptible power supply (UPS). The power supply module 4 in the embodiment of the present application can also be a storage battery.

[0052] In some implementation manners, the power supply module 4 can control the heating component 2 to be turned on for a period of time. During the period when the heating component 2 is turned on, neither the temperature sensor 11 nor the humidity sensor 12 works. After the heating component 2 finishes heating, the temperature sensor 11 and the humidity sensor 12 work again to detect the temperature and humidity of the environment. If it is still in the preset condition, the control module 3 sends an on - signal to the power supply module 4, and the heating component 2 is turned on again. This step is continuously cycled until the preset condition is not met.

[0053] In some other implementation manners, the power supply module 4 can control the heating component 2 to be turned on for a period of time. During the period when the heating component 2 is turned on, the temperature sensor 11 and the humidity sensor 12 continue to work to detect the temperature and humidity of the environment. When at least one of the ambient temperature and humidity does not reach the preset condition, the control module 3 sends a signal to turn off the heating component 2 to the power supply module 4, and the power supply module 4 controls the heating component 2 to turn off.

[0054] The anti-condensation device 100 of this embodiment is provided with a temperature sensor 11 and a humidity sensor 12 to detect whether the temperature and humidity of the area where the part to be protected 200 is located have reached the preset conditions. If the preset conditions are reached, the heating component 2 is controlled to turn on to increase the surface temperature of the part to be protected 200, thereby increasing the amount of water evaporation on the surface of the part to be protected 200, reducing the volume of dew on the part to be protected 200, and thus reducing the corrosion or even leakage short circuit problems that may be caused by dew on the part to be protected 200. In addition, the heating component 2 also reduces the humidity of the area where the part to be protected 200 is located.

[0055] Figure 2 A schematic structural diagram of a heating component in an anti-dew condensation device according to an embodiment of the present invention is schematically shown.

[0056] See also Figure 2 In some embodiments, the heating assembly 2 includes a heat generating element 21 and a fan 22 , and the fan 22 is used to blow the heat generated by the heat generating element 21 toward the part 200 to be protected.

[0057] The heat generating element 21 of the present embodiment may include a resistance wire, or may include a structure capable of generating heat, such as an electric heating tube.

[0058] The heating assembly 2 is configured to include a heat generating element 21 and a fan 22. The fan 22 can transfer the heat generated by the heat generating element 21 to the portion to be protected 200 in a timely manner, thereby increasing the evaporation rate and amount of water on the surface of the portion to be protected 200.

[0059] In some embodiments, the heat generating member 21 includes a resistance wire.

[0060] The resistance wire of this embodiment may be in a spiral shape, a strip shape, a curved shape, or the like.

[0061] The heat generating element 21 is set as a resistance wire to reduce the cost.

[0062] In some embodiments, the heating assembly 2 also includes a box body 23, the heat generating element 21 and the fan 22 are located in the box body 23, and the box body 23 is provided with a first air outlet 231 on the side facing the part 200 to be protected. The heat generating element 21 and the first air outlet 231 are spaced apart along the first direction X, and the fan 22 is arranged on the side of the heat generating element 21 away from the first air outlet 231.

[0063] The box body 23 of this embodiment may be in a rectangular parallelepiped shape or a cylindrical shape.

[0064] The shape of the first air outlet 231 in this embodiment can be circular or rectangular.

[0065] The heating component 2 is arranged to include a box body 23, and the first air outlet 231 is arranged to face the part to be protected 200. In this way, the heat can be effectively blown towards the part to be protected 200, improving the utilization rate of heat.

[0066] In some embodiments, the heat generating member 21 is arranged to surround the box body 23 along the circumferential direction of the box body 23, and a channel 211 through which the air flow generated by the fan 22 passes is formed. The channel 211 is communicated with the first air outlet 231.

[0067] The heat generating member 21 is arranged to surround the inner side of the box body 23 and form a channel 211. Then, the air flow generated by the fan 22 can directly blow towards the first air outlet 231 through the channel 211 and carry the heat generated by the heat generating member 21. Therefore, the moisture on more surfaces of the part to be protected 200 can be evaporated, the moisture evaporation speed can be increased, and the corrosion or even short - circuit problems that the moisture may cause to the part to be protected 200 can be further reduced.

[0068] Figure 3 Schematically shows another structural schematic diagram of the heating component in the anti - condensation device according to the embodiment of the present invention.

[0069] Please refer to Figure 3 , in some embodiments, the number of the heat generating members 21 is multiple. The multiple heat generating members 21 are arranged at intervals in sequence along the first direction X. The channels 211 formed by surrounding the multiple heat generating members 21 are communicated in the direction of the fan 22 pointing to the heat generating members 21, and the cross - sectional area gradually decreases in the first direction X.

[0070] In this embodiment, the multiple heat generating members 21 are arranged at intervals. The structures of the multiple heat generating members 21 can be the same or different. For example, they can be resistance wires or heating mesh structures.

[0071] Optionally, the central regions of the channels 211 formed by surrounding the multiple heat generating members 21 are arranged in sequence along the first direction. Further, the channels 211 formed by surrounding the multiple heat generating members 21 are coaxially arranged.

[0072] Optionally, the cross - sectional areas of two adjacent channels 211 in the first direction X are S1 and S2 respectively. The channel 211 with an area of S2 is closer to the fan 22 than the channel 211 with an area of S1. S1 and S2 satisfy: 2 / 3 ≤ S1 / S2 < 1.

[0073] With such an arrangement, the air flow of the fan 22 can take away the heat of the multiple heat generating members 21 when passing through the multiple channels 211, and has little influence on the size of the air flow of the fan 22. Therefore, the temperature of the air flow blown out from the first air outlet 231 can be increased, thereby further increasing the temperature of the part to be protected 200 and increasing the moisture evaporation speed.

[0074] Figure 4Another structural schematic diagram of a heating component in an anti-dew condensation device according to an embodiment of the present invention is schematically shown.

[0075] See also Figure 4 In some embodiments, there are multiple heat generating parts 21, and the multiple heat generating parts 21 are arranged in sequence along the first direction X. The channel 211 formed by the multiple heat generating parts 21 is connected in the direction where the fan 22 points to the heat generating parts 21, and the part of the box body 23 located between two adjacent heat generating parts 21 is provided with a second air outlet 232.

[0076] Optionally, the central areas of the channels 211 formed by the plurality of heat generating elements 21 are arranged in sequence along the first direction X. Furthermore, the channels 211 formed by the plurality of heat generating elements 21 are coaxially arranged.

[0077] Optionally, there are multiple second air outlets 232 located between two adjacent heat generating parts 21 , and the multiple second air outlets 232 are arranged in the box body 23 at intervals along the circumference of the box body 23 .

[0078] The shape of the second air outlet 232 of this embodiment can be circular, rectangular, elliptical, etc.

[0079] By setting a second air outlet 232 between two adjacent heat-generating parts 21, part of the wind flow comes out from the second air outlet 232, thereby increasing the temperature of the area where the protected part 200 is located, and reducing the humidity of the area where the protected part 200 is located, thereby delaying the condensation time of the protected part 200 after the heating component 2 stops working.

[0080] In some embodiments, along the direction of the fan 22 pointing to the heat-generating part 21, the box body 23 is provided with a wall of the second air outlet 232 which is inclined toward the interior of the box body 23, and the projection of the channel 211 adjacent to the second air outlet 232 and located on the side of the second air outlet 232 away from the first air outlet 231 along the first direction X on the second air outlet 232 covers at least part of the second air outlet 232.

[0081] In this embodiment, the box body 23 is provided with a wall body of the second air outlet 232 which is inclined toward the inside of the box body 23 , and the wall body may be a flat plate or a curved plate structure.

[0082] like Figure 4 As shown, the channel 211 adjacent to the second air outlet 232 and located on the side of the second air outlet 232 away from the first air outlet 231 is located on the left side of the second air outlet 232 .

[0083] With such a setting, the flowing air in the channel 211 can be made to flow towards the second air outlet 232 as much as possible, further increasing the air volume of the second air outlet 232, that is, further increasing the temperature of the area where the part to be protected 200 is located and reducing the humidity of the area where the part to be protected 200 is located.

[0084] In some embodiments, the heat generating member 21 includes a heating mesh extending from the inner surface of the box body 23 towards the central region of the box body 23, and the heating mesh surrounds to form the channel 211.

[0085] The heat generating member 21 of this embodiment includes a heating mesh extending from the inner surface of the box body 23 towards the central region of the box body 23. It should be noted that the small holes in the heating mesh itself are not the channel 211, and the channel 211 is formed by the surrounding of the heating mesh.

[0086] The heating mesh of this embodiment can be a multi-layer structure in the first direction X or a single-layer structure.

[0087] The heat generating member 21 is set as a heating mesh, and the heat generating amount of the heating mesh is relatively large, and even when surrounded, it can provide a relatively high temperature for the channel 211.

[0088] Figure 5 Schematically shows another structural schematic diagram of the anti-condensation device according to the embodiment of the present invention.

[0089] Please refer to Figure 5 , optionally, the heating mesh includes a mesh body 241 and at least two groups of first locking structures 242 and second locking structures 243. The first locking structures 242 and the second locking structures 243 are arranged on the outer edge of the mesh body 241 and are spaced apart along the first direction X. At least two groups of connected elastic structures 244 and third locking structures 245 are provided on the inner surface of the box body 23. The elastic structures 244 and the third locking structures 245 are arranged along the second direction Y, and the second direction Y is perpendicular to the first direction X. The second locking structure 243 is provided with an inclined guiding surface, and the third locking structure 245 is provided with a mating surface that cooperates with the guiding surface and is inclined. The elastic structure 244 is configured to be compressed under the extrusion of the guiding surface so that the third locking structure 245 is clamped between the first locking structure 242 and the second locking structure 243, realizing the fixation of the heating mesh relative to the box body 23. Among them, each group of first locking structures 242 and second locking structures 243 and each group of connected elastic structures 244 and third locking structures 245 are correspondingly arranged in position.

[0090] This fixing method is quick and convenient to install, and the heating mesh is also relatively firm after being installed.

[0091] The elastic structure 244 of this embodiment can be a structure such as a spring or a rubber block.

[0092] Exemplarily, there are multiple heating nets, and the channel 211 formed by the multiple heating nets is connected in the direction of the fan 22 pointing to the heat generating part 21. The multiple heating nets are connected in parallel to each other and are respectively connected to the power supply module 4. In this way, the multiple heating nets can be controlled separately, so that different numbers of heating nets can be turned on according to different needs. For example, when the difference between the ambient temperature and the temperature of the surface of the part 200 to be protected is large, a larger number of heating nets are turned on; when the difference between the ambient temperature and the temperature of the surface of the part 200 to be protected is small, a smaller number of heating nets are turned on.

[0093] Optionally, the heating net includes a net body 241 and at least two groups of elastic members and stop balls arranged at the outer edge of the net body 241, the elastic members and the stop balls are arranged and connected along the second direction Y, and the second direction Y is perpendicular to the first direction X. The elastic member is connected to the net body 241, and the stop ball is arranged on the side of the elastic member away from the net body 241. The elastic member is configured to be compressed in the second direction Y to store elastic potential energy. The wall of the box body is provided with at least two guide grooves, and the guide grooves are used to guide the stop balls to slide in and out. Each guide groove corresponds to the position of each group of elastic members and stop balls.

[0094] Exemplarily, the guide groove may be an arc-shaped groove or a V-shaped groove.

[0095] The elastic member in this embodiment may be a spring or a rubber block.

[0096] Such arrangement can facilitate the installation and removal of the heating net, that is, during installation and removal, the heating net only needs to be slid out with force, thereby facilitating maintenance and replacement.

[0102] The preset duration of this embodiment can be 20 minutes, 25 minutes, 30 minutes, 35 minutes or 40 minutes.

[0103] Setting the preset duration to be greater than or equal to 20 minutes can avoid frequent activation of the heating component 2 and can also fully evaporate the moisture on the surface of the part to be protected 200; setting the preset duration to be less than or equal to 40 minutes can reduce the activation duration and save energy.

[0104] In some embodiments, during the period when the power supply module 4 controls the heating component 2 to be activated for the preset duration, the temperature sensor 11 and the humidity sensor 12 stop working.

[0105] After the preset duration of this embodiment ends, the temperature sensor 11 and the humidity sensor 12 are reset to work again to detect the environmental conditions. If the conditions are still within the preset conditions, the heating component 2 is activated again. This step is continuously cycled until the preset conditions are no longer met.

[0106] With such a setting, the working duration of the temperature sensor 11 and the humidity sensor 12 can be reduced, and their service life can be extended.
