Description

Technical Field

[0001] The present application relates to the technical field of petroleum pipelines, and in particular to an auxiliary pipeline for petroleum transportation with a temperature control effect. Background Art

[0002] Oil refers to a mixture of gaseous, liquid or solid hydrocarbons with natural occurrences. In the oil industry, the installation and maintenance of pipeline systems is an important and complex task. During the transportation of oil, the physical properties of oil, such as viscosity and fluidity, will change with temperature. Therefore, controlling the temperature of oil is the key to ensure its safe and efficient transportation.

[0003] However, in the long-distance transportation process of existing oil transportation pipelines, due to the changes in the external environment temperature and the temperature changes of the oil itself during transportation, it is difficult to keep the oil temperature inside the pipeline stable, thereby affecting the fluidity and transportation efficiency of the oil. In response to this, some structures for monitoring oil transportation pipelines have begun to appear in the prior art to monitor the transportation temperature in real time and perform temperature compensation. However, due to the connection structure and material problems of the oil pipeline itself, the temperature change may cause the pipeline to expand or move to a certain extent, which will affect the connection status of the entire pipeline in the long run.

[0004] Therefore, the prior art needs to be further improved and enhanced. Utility Model Content

The control component includes a temperature sensor and a control cabinet. The temperature sensor is arranged on the pipeline body, and the control cabinet is connected to the temperature sensor.

[0008] As a preferred embodiment of the present application, the temperature control component includes a heating part and a cooling part, the heating part is arranged at both ends of each connecting pipe of the pipeline body, and the cooling part is arranged between the heating parts.

[0009] As a preferred embodiment of the present application, the heating part includes a heater, and the cooling part includes a water cooler.

[0010] As a preferred embodiment of the present application, the temperature control component also includes a heat insulation layer, and the heat insulation layer is sleeved on the outer wall of the cooling part.

[0011] As a preferred embodiment of the present application, the pipeline body includes multiple sections of pipes connected to each other, and the compensation component includes an expansion joint and a U-shaped connection joint. The expansion joint is arranged between the connection points of the multiple sections of the pipeline, and the U-shaped connection joint is arranged at the corner.

[0012] As a preferred embodiment of the present application, the compensation assembly further includes a sliding bracket, which is disposed between adjacent expansion joints and is slidably connected to the pipeline body.

[0013] As a preferred embodiment of the present application, the sliding bracket includes a frame body, a sliding block and a guide member. The guide member is arranged on the top of the frame body. The guide member is an arc-shaped structure. The sliding block is arranged on the inner wall of the guide member and contacts the pipeline body.

[0014] As a preferred embodiment of the present application, there is an expansion gap between the guide member and the pipeline body.

[0015] As a preferred embodiment of the present application, the guide member is arranged along the length direction of the pipeline body.

[0016] As a preferred embodiment of the present application, the temperature sensor includes an in-tube sensor and an out-tube sensor, and the outer side wall of the out-tube sensor has a protective shell.

[0017] As a preferred embodiment of the present application, a buffer layer is further provided between the support seat and the adjustment seat.

[0018] Due to the adoption of the above technical solution, the technical effects achieved by this application are:

[0019] 1. The present application provides an auxiliary oil transportation pipeline with a temperature control effect. By setting a temperature control component to adjust the temperature of the oil transportation pipeline in real time, the temperature of the oil inside the pipeline body can be effectively controlled to ensure that it is transported within a suitable temperature range, thereby improving the fluidity and transportation efficiency of the oil; and by setting a compensation component to effectively absorb the thermal expansion or contraction of the pipeline body caused by temperature changes, the pipeline is prevented from being damaged and the service life of the pipeline is increased; in addition, the setting of the temperature sensor and the control cabinet can monitor the temperature of the oil inside the pipeline body in real time, and adjust the temperature control component through the control cabinet to maintain the stability of the oil temperature, thereby improving the degree of intelligence to a certain extent.

[0020] 2. As a preferred embodiment of the present application, the present application arranges a temperature control component including a cooling part and a heating part, and arranges them in different areas, so as to avoid mutual influence between devices as much as possible by arranging the heating part at both ends of the pipeline body.

[0030] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0033] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0034] In the present application, unless otherwise clearly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example" or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0035] like Figure 1As shown, the present application provides an auxiliary oil transportation pipeline with a temperature control effect, the auxiliary oil transportation pipeline includes a pipeline body 10, a temperature control component 20, a control component 30 and a compensation component 40, the temperature control component 20 is arranged on the outer wall of the pipeline body 10, the compensation component 40 is evenly spaced in the length direction of the pipeline body 10, the control component 30 includes a temperature sensor 31 and a control cabinet 32, the temperature sensor 31 is arranged on the pipeline body 10, and the control cabinet 32 ​​is connected to the temperature sensor 31.

[0036] Among them, Figure 1 As shown, since oil transportation generally requires a long distance, the oil transportation auxiliary pipeline of the present application is a longer transportation pipeline formed by connecting multiple pipelines to each other, and the oil transportation auxiliary pipeline of the present application refers to a pipeline that can provide appropriate temperature control assistance for oil transportation, so it is called a transportation auxiliary pipeline.

[0037] As a preferred embodiment of the present application, the temperature control component 20 includes a heating part 21 and a cooling part 22 . The heating part 21 is arranged at both ends of each connecting pipe of the pipeline body 10 , and the cooling part 22 is arranged between the heating parts 21 .

[0038] It is understandable that if Figure 1 As shown, multiple heating parts 21 and cooling parts 22 can be provided. Since the pipeline body 10 is composed of multiple pipes connected to each other, heating parts 21 can be provided at both ends of the pipeline to heat the oil passing through the heating parts 21 to prevent the oil from becoming more viscous due to low temperature during transportation, resulting in difficulty in flow.

[0039] Furthermore, the cooling part 22 is arranged between the heating parts 21. When heating is not required or the heating temperature is too high, the cooling part 22 can also be used for cooling. The separate area arrangement of the two can also reduce the mutual influence between the two.

[0040] Specifically, regarding the arrangement of the heating unit 21 and the cooling unit 22, in an optional embodiment, the heating unit 21 includes a heater, and the cooling unit 22 includes a water cooler, wherein the heater can be an electric heater, which is suitable for applications where precise temperature control is required. They can respond quickly to temperature changes and do not produce exhaust gas from combustion, so they are more suitable in some occasions with high environmental requirements. The water cooling unit 22 uses water as a cooling medium and can provide an efficient cooling effect. The high heat capacity and high thermal conductivity of water make it an ideal cooling medium.

[0041] Of course, this structure is only one of the preferred implementations. The heating part 21 may also use a steam heater or a hot oil heater, and the cooling part 22 may also use an air cooler and a compression refrigeration device.

[0042] In addition, the heating part 21 and the cooling part 22 may be disposed outside the pipe body 10 to conduct heat through the side wall of the pipe body 10 .

[0043] In order to reduce the loss of temperature, the temperature control assembly 20 further includes a heat insulation layer 23, and the heat insulation layer 23 is sleeved on the outer wall of the cooling portion 22. Figure 1 As shown, the heat insulating layer 23 is sleeved on the outer wall of the pipeline body 10 and can wrap the cooling part 22, and can be set as an isolation layer or isolation space to reduce heat exchange and ensure the independence and efficiency of the system.

[0044] As a preferred implementation of the present application, Figure 1 As shown, the pipeline body 10 includes multiple sections of pipelines connected to each other, and the compensation component 40 includes an expansion joint 41 and a U-shaped connection joint 42. The expansion joint 41 is arranged between the connections of the multiple sections of pipelines, and the U-shaped connection joint 42 is arranged at the corner.

[0045] The expansion joint 41 can be used as a compensator for temperature changes in the pipeline body 10. When the pipeline expands due to heating, the expansion joint 41 will stretch, thereby allowing the pipeline to have a certain displacement in the axial and radial directions, reducing the stress caused by thermal expansion. The specific structure of the expansion joint 41 is relatively mature in the prior art, so this application will not make a specific description here.

[0046] As for the U-shaped connection joint 42, since the oil pipeline is long and there may be corners, the U-shaped connection joint 42 is provided to play a role similar to the expansion joint 41 at the corner, and it can provide a certain natural compensation ability, absorb part of the displacement, and reduce the stress on the fixed point.

[0047] In a preferred embodiment, Figure 1 As shown, the compensation assembly 40 further includes a sliding bracket 43 , which is disposed between adjacent expansion joints 41 , and the sliding bracket 43 is slidably connected to the pipeline body 10 .

[0048] As a preferred embodiment of the present application, the sliding bracket 43 includes a frame body 431, a sliding block 432 and a guide member 433. The guide member 433 is arranged on the top of the frame body 431. The guide member 433 is an arc-shaped structure. The sliding block 432 is arranged on the inner wall of the guide member 433 and contacts with the pipeline body 10.

[0049] Among them, Figure 1As shown, the frame 431 can adopt a more common support frame structure, the guide member 433 is a semi-annular arc structure and extends along the length direction to provide an axial guide space for the axial expansion displacement of the pipeline due to temperature, thereby ensuring the safety and reliability of the pipeline; and the sliding block 432 is the part of the bracket that is in direct contact with the pipeline, and is usually made of low-friction material, such as polytetrafluoroethylene (PTFE), graphite or other wear-resistant materials to reduce the friction when the pipeline slides. Although it is called a sliding block 432, its structure is actually adapted to the inner wall of the guide member 433 to ensure that the pipeline in contact with it can contact the sliding block 432.

[0050] Furthermore, there is an expansion gap between the guide 433 and the pipe body 10, and the expansion gap should not be too large. It is necessary to reserve a certain space for the radial expansion of the pipe body 10 to reduce the extrusion between the pipe body 10 and the guide 433. It is understandable that when installing the sliding bracket 43, it should be ensured that the pipe can slide freely on the bracket without being affected by excessive friction or lateral force. In addition, the installation position of the sliding bracket 43 should match the design of the pipeline system so as to effectively absorb the axial displacement during thermal expansion.

[0051] As a preferred implementation of the present application, Figure 1 The temperature sensor 31 includes an inner tube sensor 311 and an outer tube sensor 312. The outer wall of the outer tube sensor 312 has a protective shell. The inner tube sensor 311 can be installed inside the pipeline using a special joint or insertion device to ensure accurate measurement of the temperature of the oil. This type of sensor can be an insertion type thermal resistor, a thermocouple or an optical fiber temperature sensor 31, etc.

[0052] Furthermore, since oil itself is somewhat corrosive, the in-pipe sensor 311 may be installed in a protective sleeve or probe to isolate direct contact with oil and reduce fluid dynamics effects. The housing may be made of corrosion-resistant materials, such as stainless steel or special alloys, to resist chemicals in oil.

[0053] As for the external pipe sensor 312, it can monitor the temperature of the outer wall of the pipe to evaluate the insulation effect or detect the influence of the external environment on the pipe temperature. A temperature sensor 31 is installed on the outer wall of the pipe. This sensor can be a surface mounted thermal resistor or a thermocouple, which measures the temperature by fixing it on the pipe wall.

[0054] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0055] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
