Description

Technical Field

[0001] This utility model relates to the field of heat exchange station technology, specifically to an unattended heat exchange station that improves thermal energy utilization. Background Technology

[0002] A heat exchange station is a device that uses heat exchange equipment to exchange heat between high-temperature hot water or steam generated by a heat source and low-temperature circulating water on the user side, thereby achieving efficient energy transfer from the heat source to the heat user without directly mixing the two media.

[0003] Traditional heat exchange stations typically have a single heat exchanger structure. Therefore, in actual operation, the heat exchange load is fixed and cannot be dynamically adjusted according to changes in actual heat load, resulting in energy waste. At the same time, the heat transfer process of the heat exchange station relies on a single layer of pipes, which leads to a large amount of heat loss during the heat transfer process, resulting in low thermal energy utilization of the heat exchange station.

Another set of connecting pipes is connected to the heat-using structure, which is a heat energy user. The heat-using structure is connected to the secondary water supply structure and the secondary return water structure via connecting pipes respectively.

[0011] Using the above technical solution, the device can be connected to the heat source structure and the heat-using structure respectively by means of connecting pipes.

[0012] Preferably, the secondary water return structure is connected to the outlet of the water pump via a pipe, and the inlet of the water pump is connected to a water replenishment tank.

[0013] Using the above technical solution, a water pump can be used to replenish the water in the water tank into the system.

[0014] Preferably, the outer surfaces of the through pipe and the connecting pipe are respectively provided with heat insulation structures. The heat insulation structures achieve heat separation through protective sleeves. The heat insulation structures include protective sleeves, which are hollow sandwich structures.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 This utility model provides a technical solution: an unattended heat exchange station for improving thermal energy utilization, including a No. 1 heat exchanger 1, a No. 2 heat exchanger 2, a No. 1 interface 3, a No. 2 interface 4, a No. 3 interface 5, a No. 4 interface 6, a through pipe 7, a heat source structure 8, a heat-using structure 9, a connecting pipe 10, a No. 1 solenoid valve 11, a No. 2 solenoid valve 12, a No. 3 solenoid valve 13, a No. 4 solenoid valve 14, a water supply tank 15, a water pump 16, a protective sleeve 17, and a controller 18.

[0031] A No. 1 interface 3 is provided through the side surface of heat exchanger 1. A No. 2 interface 4 is provided below the No. 1 interface 3. A No. 3 interface 5 and a No. 4 interface 6 are respectively arranged parallel to the No. 1 interface 3 and the No. 2 interface 4, the No. 3 interface 5, and the No. 4 interface 6 are respectively provided through the side surface of heat exchanger 1. A No. 2 heat exchanger 2 is symmetrically arranged on one side of heat exchanger 1. Heat exchanger 1 and heat exchanger 2 have the same structure. Heat exchanger 1 and heat exchanger 2 together constitute the heat exchange unit structure in the heat exchange station. A through pipe 7 is provided in the heat exchange unit structure to realize the connection between heat exchanger 1 and heat exchanger 2. The connection between heat exchanger 1 and heat exchanger 2 is via a C-shaped through-pipe 7. Both ends of the through-pipe 7 are connected to interface 3 on the surfaces of heat exchanger 1 and heat exchanger 2, respectively. There are four through-pipes 7. The remaining three through-pipes 7 are connected to interfaces 4, 5, and 6 on the surfaces of heat exchanger 1 and heat exchanger 2, respectively. These four through-pipes 7, together with interfaces 3, 4, 5, and 6, form a media transmission unit. This media transmission unit, consisting of the through-pipes 7 and interface 3, is designated as a primary water supply structure. The medium transmission unit formed by pipe 7 and interface 4 is marked as a primary return water structure; the medium transmission unit formed by through pipe 7 and interface 5 is marked as a secondary water supply structure; and the medium transmission unit formed by through pipe 7 and interface 6 is marked as a secondary return water structure. Two solenoid valves 11 are installed on through pipe 7 at the primary water supply structure; two solenoid valves 12 are installed on through pipe 7 at the primary return water structure; two solenoid valves 13 are installed on through pipe 7 at the secondary water supply structure; and two solenoid valves 14 are installed on through pipe 7 at the secondary return water structure. The primary water supply structure is connected via... Pipe 10 is connected to heat source structure 8, which supplies heat to the thermal power plant. Heat source structure 8 is connected to primary return water structure through connecting pipe 10. Two sets of connecting pipe 10 are symmetrically arranged. Another set of connecting pipe 10 is connected to heat-using structure 9, which is a heat energy user. Heat-using structure 9 is connected to secondary water supply structure and secondary return water structure through connecting pipe 10. The outlet of water pump 16 is connected to the secondary return water structure through a pipe. The inlet of water pump 16 is connected to water supply tank 15. Controller 18 is installed on the surface of connecting pipe 10. Controller 18 is connected to computer via wireless signal.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, when the heating demand at heat-using structure 9 is high, the controller 18 controls all four solenoid valves (11, 12, 13, and 14) at heat exchangers 1 and 2 within the heat exchange unit structure to open simultaneously, allowing heat exchangers 1 and 2 to operate concurrently. The thermal power plant at heat source structure 8 delivers high-temperature hot water to the primary water supply structure via connecting pipe 10. The high-temperature hot water flows through the connecting pipe 7 into heat exchangers 1 and 2 respectively, exchanging heat with the low-temperature water. The connecting pipe 7 of the primary return water structure then delivers the heat-exchanged low-temperature hot water through the connecting pipe... The hot water, after being heated by heat exchange, is sent back to the thermal power plant via pipe 7 and connecting pipe 10 of the secondary water supply structure to the heat-using structure 9 to meet the user's heating needs. The low-temperature water that has lost heat returns to the No. 1 heat exchanger 1 and No. 2 heat exchanger 2 in the heat exchange unit structure via the secondary return water structure for reuse. During the heating process, some hot water will be lost due to evaporation, leakage and other reasons, and the amount of secondary return water will gradually decrease. When the water level at the secondary return water structure drops, the water supply tank 15 replenishes the secondary return water structure with water under the action of water pump 16 to ensure the normal circulation of the medium in the system and maintain stable heating.

[0033] When the heating demand at heat-using structure 9 is low, close solenoid valves 11, 12, 13, and 14 at end 2 of heat exchanger 2, so that heat exchanger 1 is running while heat exchanger 2 is closed, so that the heat exchange station is in a low-load operation state to avoid energy waste. The medium circulation process in the rest of the system is the same as above.

[0034] The outer surfaces of the through pipe 7 and the connecting pipe 10 are respectively provided with heat insulation structures. The heat insulation structures separate heat through the protective sleeve 17. The heat insulation structure includes the protective sleeve 17, which is a hollow sandwich structure. Air is filled into the sandwich of the protective sleeve 17. The surface of the protective sleeve 17 is a corrugated structure. The protective sleeve 17 wraps around the outer surfaces of the through pipe 7 and the connecting pipe 10.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, during the operation of the device, the protective sleeve 17 on the outer surface of the through pipe 7 and the connecting pipe 10 has a heat insulation effect, reducing heat loss. The air in the hollow interlayer of the protective sleeve 17 and the corrugated surface can reduce the heat conduction efficiency, reduce the heat loss during the operation of the device, and thus improve the heat energy utilization rate of the heat exchange station.

[0036] Working principle: When using this unattended heat exchange station that improves thermal energy utilization, the heat exchange station is remotely controlled by the controller 18, which controls the on / off state of heat exchanger 1 and heat exchanger 2. This allows for flexible adjustment as needed, reducing the energy consumption of the heat exchange station. The high-temperature heat medium from the heat source structure 8 flows into the primary water supply structure through the connecting pipe 10, and enters heat exchanger 1 and heat exchanger 2 for heat exchange. The heated secondary medium is transported from the secondary water supply structure to the heat-using structure 9 through the connecting pipe 10 to meet the user's heat demand. Protective sleeves 17 are installed on the outer surface of the through pipe 7 and the connecting pipe 10. The protective sleeves 17 can reduce heat loss during the heat transfer process, improve the overall thermal energy utilization rate, and increase the overall practicality.
