Description

Technical Field

[0001] This utility model relates to the field of heating pipeline technology, specifically to a pipeline with switchable heat sources. Background Technology

[0002] Heating pipelines are pipeline systems specifically designed to transport steam or hot water. Their core function is to efficiently transport the heat energy generated by heat sources such as boilers to indoor heating equipment (such as radiators, underfloor heating, etc.) through heat media such as steam and hot water. Depending on the medium, they can be divided into two main categories: steam pipelines (transporting high-temperature steam) and hot water pipelines (transporting high-temperature or low-temperature hot water).

[0003] Currently, heating pipeline systems in the chemical industry are mostly based on a single heat source, lacking systems that can supply heat from multiple sources simultaneously. This not only fails to provide users with customized heating modes, but also makes it impossible to avoid the risk of heating interruptions due to a single heat source. Furthermore, the choice of heating mode is based on the market price of the heat source, which cannot meet the requirements for cost reduction and efficiency improvement in the chemical industry. Therefore, a pipeline system with switchable heat sources is proposed. By setting up organic natural gas transmission pipes, steam transmission pipes, and other medium transmission pipes, it can operate in an organic heat carrier natural gas furnace heating mode or a 10MPa steam heat exchanger heating mode.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] By installing organic natural gas transmission pipes, steam transmission pipes, and other media transmission pipes, heating modes such as organic heat carrier natural gas furnace heating and 10MPa steam heat exchanger heating can be implemented. Figure 1-2 As shown, the present invention discloses a pipeline with a switchable heat source, comprising an organic natural gas transmission pipe 3, a steam transmission pipe 4, and other medium transmission pipes 5, which are arranged sequentially from top to bottom. A first support plate 1 is fitted onto one end of each of the organic natural gas transmission pipes 3, steam transmission pipes 4, and other medium transmission pipes 5, and a second support plate 2 is fitted onto the other end of each of the organic natural gas transmission pipes 3, steam transmission pipes 4, and other medium transmission pipes 5. A preheating component 6 is fitted onto the outer side of each of the organic natural gas transmission pipes 3, steam transmission pipes 4, and other medium transmission pipes 5 located between the first support plate 1 and the second support plate 2.

[0022] The preheating component 6 includes a heat insulation sleeve 601 fixedly sleeved on the outside of the organic natural gas conveying pipe 3, the steam conveying pipe 4 and the other medium conveying pipe 5. A heat-conducting sleeve 602 is sleeved on the inner side of the heat insulation sleeve 601 located outside the organic natural gas conveying pipe 3, the steam conveying pipe 4 and the other medium conveying pipe 5. Electric heating wires 603 are embedded equidistantly inside the heat-conducting sleeve 602.

[0023] In use, the organic natural gas transmission pipe 3, steam transmission pipe 4 and other medium transmission pipe 5 can be used for heating from multiple heat sources, and the heating pipes can be switched freely. The corresponding organic natural gas transmission pipe 3, steam transmission pipe 4 and other medium transmission pipe 5 can be preheated through the heat-conducting sleeve 602 and its internal electric heating wire 603.

[0024] For example, such as Figure 1As shown, this utility model also includes a one-way valve 12 connected to one end of the organic natural gas conveying pipe 3, the steam conveying pipe 4 and the other medium conveying pipe 5 through a threaded groove, and a collecting pipe 8 connected to the end of the one-way valve 12 away from the organic natural gas conveying pipe 3, the steam conveying pipe 4 and the other medium conveying pipe 5 through a pipe.

[0025] When in use, the one-way valve 12 is designed to prevent the backflow of the medium flowing into the collection pipe 8.

[0026] For example, such as Figure 1 As shown, the present invention also includes a discharge pipe 9 connected to one side of the collecting pipe 8 via a pipe joint, a first valve 10 sleeved on the outside of the discharge pipe 9, and a first flow meter 11 sleeved on the outside of the discharge pipe 9 at one end of the first valve 10.

[0027] When in use, the first valve 10 is opened to allow the medium in the collecting pipe 8 to flow to the user end through the discharge pipe 9. The first flow meter 11 is set to detect and display the flow rate of the medium in the first flow meter 11.

[0028] For example, such as Figure 1 As shown, the present invention also includes a second valve 14 connected to one end of the organic natural gas conveying pipe 3, the steam conveying pipe 4, and the other medium conveying pipe 5 away from the top via a threaded groove, and a second flow meter 13 is sleeved on the outside of the organic natural gas conveying pipe 3, the steam conveying pipe 4, and the other medium conveying pipe 5 near the second valve 14.

[0029] When in use, the corresponding second valve 14 is opened to allow the hot medium to flow into the organic natural gas transmission pipe 3, the steam transmission pipe 4, or other medium transmission pipe 5. The second flow meter 13 is used to detect and display the flow rate of the medium in the organic natural gas transmission pipe 3, the steam transmission pipe 4, and the other medium transmission pipe 5.

[0030] For example, such as Figure 1 As shown, the present invention also includes a thermostat 7 mounted on one side of the heat insulation sleeve 601 via a mounting base. The detection end of the thermostat 7 is located inside the heat-conducting sleeve 602, and the current output end of the thermostat 7 is electrically connected to the current input end of the electric heating wire 603 via a power cord.

[0031] During use, the heating of the electric heating wire 603 and its heating temperature can be controlled by the thermostat 7.

[0032] For example, such as Figure 2 As shown, the present invention also includes that the heat insulation sleeve 601 is made of glass fiber material and the heat-conducting sleeve 602 is made of heat-conducting silicone rubber material.

[0033] When in use, the heat insulation sleeve 601 made of fiberglass material can reduce the heat loss of the heat conduction sleeve 602. The heat conduction sleeve 602 made of thermally conductive silicone rubber material has the functions of insulation and heat conduction, and can conduct the temperature of the electric heating wire 603 to the corresponding pipe.

[0034] For example, such as Figure 1 As shown, the present invention also includes, the organic natural gas conveying pipe 3, the steam conveying pipe 4 and the other medium conveying pipe 5 are fitted with heat insulation sleeves 15 on the outer sides of the heat insulation sleeve 601 at both ends.

[0035] When in use, the insulation jacket 15 can reduce heat loss of the medium in the organic natural gas transmission pipe 3, steam transmission pipe 4 and other medium transmission pipe 5.

[0036] In use, the second valve 14 at one end of the organic natural gas conveying pipe 3 is connected to the organic heat carrier natural gas furnace, the second valve 14 at one end of the steam conveying pipe 4 is connected to the 10MPa steam heat exchanger, the second valve 14 at one end of the other medium conveying pipe 5 is connected to other heating equipment, and one end of the discharge pipe 9 is connected to the heat-using equipment.

[0037] When the supply of combustion medium for the organic thermal carrier natural gas furnace is insufficient or the market price is too high, resulting in higher energy consumption per unit compared to products heated by 10MPa steam, the heating mode of the organic thermal carrier natural gas furnace can be switched to the heating mode of the 10MPa steam heat exchanger. The specific implementation is as follows: Under the condition of independent heating by the organic thermal carrier natural gas furnace, the heating mode of the 10MPa steam heat exchanger can be switched according to demand. The steam heating unit needs to be notified in advance to increase the load and generate heat. The electric heating wire 603 is controlled by the temperature controller 7 to heat the heat-conducting sleeve 602. After the heat-conducting sleeve 602 is heated, the heat is transferred to the steam transmission pipe 4. When the steam is delivered to the user end, the middle section of the steam transmission pipe 4 and the user equipment are fully preheated to ensure that no air hammer is generated in the pipeline during steam transmission. Before the 10MPa steam heat exchanger is started, the second valve 14 and the first valve 10 at one end of the steam transmission pipe 4 are opened to shut down the organic thermal carrier natural gas furnace and supply heat to the 10MPa steam heat exchanger.

[0038] When the 10MPa steam supply from the 10MPa steam heat exchanger is insufficient or the market price is too high, resulting in higher energy consumption per unit compared to products heated by the organic heat carrier natural gas furnace, the heating mode of the 10MPa steam heat exchanger can be switched to the heating mode of the organic heat carrier natural gas furnace. Specifically, under the condition of heating solely from the 10MPa steam heat exchanger, the system switches to the heating mode of the organic heat carrier natural gas furnace as needed. Before the organic heat carrier natural gas furnace starts operating, the temperature controller 7 controls the operation of the electric heating wire 603 to heat the heat-conducting jacket 60. 2. Heating: After the heat-conducting jacket 602 is heated, the heat is transferred to the organic natural gas transmission pipe 3. One group of people on site slowly opens the second valve 14 at one end of the organic natural gas transmission pipe 3, while the other group slowly closes the second valve 14 at one end of the steam transmission pipe 4. The two groups on site try to keep the valve adjustments consistent. At the same time, the central control slowly reduces the load of the 10MPa steam heat exchanger and increases the load of the organic heat carrier natural gas furnace. The on-site and central control work together until the 10MPa steam heat exchanger is shut down and the system is completely heated by the organic heat carrier natural gas furnace.

[0039] Two groups of personnel operate simultaneously to slowly close the second valve 14 on the organic natural gas transmission pipe 3 or the steam transmission pipe 4 and slowly open the second valve 14 at one end of the other medium transmission pipe 5, so that other hot media can flow into the other medium transmission pipe 5 and be transported to the user end through the other medium transmission pipe 5.

[0040] Preheating components 6 are installed on the organic natural gas conveying pipe 3, steam conveying pipe 4, and other medium conveying pipe 5, which can preheat the organic natural gas conveying pipe 3, steam conveying pipe 4, or other medium conveying pipe 5 when needed. The second flow meter 13 is set to display the flow rate of the medium in the organic natural gas conveying pipe 3, steam conveying pipe 4, and other medium conveying pipe 5. The one-way valve 12 is set to prevent the medium flowing into the collecting pipe 8 from flowing back into the organic natural gas conveying pipe 3, steam conveying pipe 4, and other medium conveying pipe 5. The first valve 10 is used to detect the flow rate of the medium flowing out of the discharge pipe 9.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
