[0031] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] like Figure 1-Figure 3 As shown, the regeneration tower and heating network coupling system of the embodiment of the present invention includes: a regeneration tower 1, a heating component 2, a heat pump component 3 and a heat exchange component 4.

[0033] The regeneration tower 1 includes a preheating section 11, a heating section 12 and a cooling section 13 arranged in sequence along the flow direction of the adsorbent. The heating assembly 2 includes a heating part 21 and a heat supply part 22, the heating part 21 is connected to the regeneration tower 1 and is placed in the heating section 12, the heat supply part 22 is connected to the heating part 21, and the heat supply part 22 has a steam inlet 221 and a steam outlet 222, so that the steam can be sequentially passed into the heating part 21 through the steam inlet 221 and the heat supply part 22. The heat pump assembly 3 has an input port 31 and an output port 32, the input port 31 is connected to the steam outlet 222, so that the heat supply part 22 passes the steam after heat exchange into the heat pump assembly 3. The heat exchange assembly 4 is connected to the heat network pipeline 100 of the heat supply network, and the heat exchange assembly 4 includes a heat exchange element 41, which is connected to the output port 32, so as to use the heat energy generated by the heat pump assembly 3 to heat the heat network circulating water in the heat exchange element 41.

[0034] Specifically, Figure 1 As shown, the preheating section 11, the heating section 12 and the cooling section 13 are arranged in sequence from top to bottom. The preheating section 11 is located at the starting end of the regeneration tower 1, and is used to preheat the adsorbent to a certain temperature so that the subsequent heating section 12 can perform more efficient heat exchange. The heating section 12 is located after the preheating section 11 and is the core area for high-temperature regeneration of the adsorbent. The heating section 12 is provided with a heating part 21 of the heating assembly 2 inside to provide the necessary heat. The cooling section 13 is located after the heating section 12, and is used to cool the regenerated adsorbent to a suitable temperature so that the adsorption operation can be performed again.

[0035] The heating part 21 is directly connected to the heating section 12 of the regeneration tower 1, so that the steam flowing inside the heating part 21 provides heat to complete the regeneration of the adsorbent in the heating section 12. The heat supply part 22 is connected to the heating part 21 through a pipeline and is provided with a steam inlet 221 and a steam outlet 222. The steam inlet 221 receives high-temperature steam supplied from the outside. After the steam exchanges heat with the adsorbent in the regeneration tower 1 in the heating part 21, it enters the heat pump assembly 3 through the steam outlet 222 to drive the heat pump assembly 3 to operate and generate heat.

[0036] The input port 31 is connected to the steam outlet 222 of the heating component 2 to receive the steam after heat exchange. The output port 32 is connected to the heat exchange element 41 of the heat exchange component 4. The heat energy released at the output port 32 is used to heat the heat network circulating water in the heat exchange element 41.

[0037] The heat exchanger 41 is connected to the output port 32 of the heat pump assembly 3. The heat energy generated by the heat pump assembly 3 is transferred to the circulating water of the heat network through the heat exchanger 41 to increase the temperature of the hot water. The heat exchanger assembly 4 is connected to the heat network pipeline 100 of the heat supply network so that the circulating water of the heat network is heated by the heat exchanger 41 and then transported to the heat supply.

[0038] It should be noted that the heat pump assembly 3 may be a device that generates heat by using steam drive, such as a steam jet heat pump.

[0039] That is to say, the application of the heat pump component 3 of the regeneration tower and the heating network coupling system of the embodiment of the present invention improves the thermal efficiency of the heating system, so that the heating system can provide more heat under the same heat energy input. By recovering the heat energy of high-temperature steam and using it in the heat pump component 3 and the heat exchange component 4, the utilization efficiency of heat energy is improved and the operating cost is reduced.

[0040] In some embodiments, the heat exchange element 41 includes a first heat exchange pipeline 411 and a second heat exchange pipeline 412, the first heat exchange pipeline 411 is connected to the heat network pipeline 100, the second heat exchange pipeline 412 is connected to the heat pump assembly 3, and the second heat exchange pipeline 412 is arranged around the first heat exchange pipeline 411 along the circumference of the first heat exchange pipeline 411.

[0041] Specifically, Figure 1 As shown, the first heat exchange pipeline 411 is connected to the heat network pipeline 100 of the heat supply network, and is used to directly receive and transport the heat network circulating water. The circulating water flows in the first heat exchange pipeline 411 and absorbs heat from the heat pump component 3 through heat exchange. The second heat exchange pipeline 412 is connected to the output port 32 of the heat pump component 3, and is used to transfer the heat energy output from the heat pump component 3 to the heat network circulating water.

[0042] It is understandable that the second heat exchange pipeline 412 is arranged around the circumference of the first heat exchange pipeline 411, so that the second heat exchange pipeline 412 surrounds the first heat exchange pipeline 411 to form a surrounding structure. Thereby increasing the contact area of ​​heat exchange and improving the heat exchange efficiency. The heat energy generated by the heat pump assembly 3 can be more effectively transferred to the circulating water of the heat network.

[0043] In addition, the surrounding heat exchange pipelines help to evenly distribute the heat flow, avoiding local overheating or overcooling during the heat exchange process, thereby improving the uniformity and stability of the heat exchange. Of course, the relative position and structure of the first heat exchange pipeline 411 and the second heat exchange pipeline 412 can adapt to the heat exchange requirements under different working conditions and improve the flexibility of the system.

[0044] In some embodiments, the distance between the inlet end of the first heat exchange pipeline 411 and the outlet end of the first heat exchange pipeline 411 is smaller than the distance in the extension direction of the first heat exchange pipeline 411 .

[0045] It is understandable that if Figure 2As shown, the distance between the inlet and outlet of the first heat exchange pipeline 411 is short, while the distance in the extension direction is long. That is, the first heat exchange pipeline 411 presents a compact serpentine or curved shape in the spatial layout. The inlet end of the first heat exchange pipeline 411 is connected to the heat network pipeline 100 of the heat supply network to receive the heat network circulating water; the outlet end of the first heat exchange pipeline 411 returns the heated circulating water to the heat network.

[0046] That is to say, the second heat exchange pipeline 412 is defined between the inner wall of the heat exchange element 41 and the outer peripheral wall of the first heat exchange pipeline 411, and the heat pump assembly 3 can pass the heat source into the second heat exchange pipeline 412 and exchange heat with the first heat exchange pipeline 411. The first heat exchange pipeline 411 adopts a curved or serpentine design, which increases the contact area between the circulating water flow and the wall of the second heat exchange pipeline 412, which is conducive to heat transfer, so that the circulating water in the heat network can absorb more heat energy.

[0047] Optionally, the second heat exchange pipeline 412 extends in a spiral shape, and the first heat exchange pipeline 411 is adapted to the second heat exchange pipeline 412. That is, the second heat exchange pipeline 412 adopts a spiral design so that it spirals and extends around the first heat exchange pipeline 411. The surface area of ​​heat exchange between the first heat exchange pipeline 411 and the second heat exchange pipeline 412 is increased, and the heat exchange efficiency is improved. The first heat exchange pipeline 411 and the second heat exchange pipeline 412 are adapted to each other so that the size, shape and heat exchange characteristics of the two are carefully designed to ensure the optimal heat exchange process between the two.

[0048] In other embodiments, Figure 3 As shown, the heat exchange element 41 includes a first flow channel cavity 413, a second flow channel cavity 414 and a heat exchange cavity 415. The first flow channel cavity 413 and the second flow channel cavity 414 are both connected to the heat network pipeline 100 of the heat supply network, the heat exchange cavity 415 is connected to the heat pump assembly 3, and the second flow channel cavity 414 is arranged around the first flow channel cavity 413 along the circumference of the first flow channel cavity 413, and the heat exchange cavity 415 is arranged around the second flow channel cavity 414 along the circumference of the second flow channel cavity 414.

[0049] Specifically, Figure 3 As shown, the first flow channel cavity 413 is connected to the heat network pipe 100 of the heat supply network for receiving the heat network circulating water. The circulating water flows in the first flow channel cavity 413, ready to exchange with the heat energy from the heat pump assembly 3. The second flow channel cavity 414 is also connected to the heat network pipe 100 of the heat supply network, but it surrounds the circumference of the first flow channel cavity 413 to provide more surface area for heat exchange and ensure uniform distribution of heat energy. The heat exchange cavity 415 is connected to the heat pump assembly 3 and is the core area where heat exchange occurs. The heat energy generated by the heat pump assembly 3 is exchanged in the heat exchange cavity 415 with the heat network circulating water in the second flow channel cavity 414.

[0050] It is understandable that the second flow channel cavity 414 is arranged around the circumference of the first flow channel cavity 413, which can increase the contact area of ​​heat exchange, so that heat energy can be more effectively transferred to the circulating water of the heat network. The second flow channel cavity 414 can also be used to wrap around to avoid the temperature of the circulating water in the first flow channel cavity 413 from decreasing, to ensure the minimum temperature difference between the first flow channel cavity 413 and the second flow channel cavity 414, thereby avoiding the problem of local overheating or overcooling, and improving the uniformity of heat exchange.

[0051] In some embodiments, the heat exchange assembly 4 further includes a mixing element 42, which is connected to the heat exchange element 41, and the mixing element 42 is located downstream of the heat exchange element 41 in the flow direction of the circulating water in the heat network.

[0052] It is understandable that if Figure 1 As shown, the mixing element 42 is connected to the heat exchange element 41, so that the heat network circulating water after heat exchange in the heat exchange element 41 passes into the mixing element 42, thereby ensuring that the heat network circulating water is fully mixed and the uniformity of the circulating water temperature is ensured.

[0053] In some embodiments, the regeneration tower and heating network coupling system of the embodiment of the present invention further includes a water supply pipeline 5 , and the water supply pipeline 5 is connected to the mixing element 42 .

[0054] It is understandable that if Figure 1 As shown, the water supply pipeline 5 is a pipeline connected to the mixing element 42, which is used to supply water to the mixing element 42. During the flow of circulating water in the heating network, an appropriate amount of water is added as needed to maintain the normal operation of the heating network system. The water supply pipeline 5 also includes a water supply pump, which is used to send preheated water into the mixing element 42. The water supply pump can provide an appropriate amount of water and pressure according to the actual needs of the system. In addition, the water supply pump can adopt variable frequency speed regulation technology, which can automatically adjust the operating speed of the pump according to the actual needs of the circulating water in the heating network, thereby adjusting the water supply amount and water supply pressure.

[0055] In some embodiments, the regeneration tower and heating network coupling system of the embodiment of the present invention also includes a preheating component 6, which is connected to the water supply pipeline 5. The preheating component 6 has a preheating inlet, which is connected to the heat pump component 3 so that the heat energy generated by the heat pump component 3 can preheat the water supply pipeline 5.

[0056] Specifically, Figure 1 As shown, the preheating element 6 is a component connected to the water supply pipeline 5, and its main function is to preheat the water supply by using the heat energy generated by the heat pump component 3. The preheating element 6 has a preheating inlet, which is connected to the heat pump component 3. In this way, the heat energy generated by the heat pump component 3 can be transferred to the preheating element 6 through the preheating inlet.

[0057] That is, the preheating element 6 is connected to the water supply pipeline 5 so that the preheated water can directly enter the water supply pipeline 5 and then be sent to the mixing element 42 to mix with the circulating water of the heating network. The use of the preheating element 6 reduces the energy required to heat the water supply, thereby reducing the operating cost of the system. The preheating element 6 can ensure that the water supply reaches a suitable temperature before entering the mixing chamber, which helps to optimize the temperature distribution of the circulating water of the heating network and improve the heating efficiency.

[0058] In some embodiments, the regeneration tower and heating network coupling system of the embodiment of the present invention further includes a control component, which includes a control valve, and the control valve is arranged at the output port 32 to control the amount of heat energy discharged from the output port 32.

[0059] It is understandable that the control assembly includes a control valve, which is arranged at the output port 32 of the heat exchange assembly 4 and is used to control the amount of heat energy discharged from the output port 32. By adjusting the opening of the control valve, the output of heat energy can be accurately controlled.

[0060] In some embodiments, the control component also includes a detection element, which is connected to the outlet of the mixing element 42, and the detection element is electrically connected to the control valve, so that the detection element transmits the outlet temperature information of the mixing element 42 to the control valve, and the control valve adjusts the amount of heat energy discharged from the output port 32 according to the detection information.

[0061] It is understandable that the detection element is disposed at the outlet of the mixing element 42 to monitor the temperature at the outlet of the mixing element 42. This temperature information is a key parameter for adjusting the heat output.

[0062] In other words, the control component enables the system to automatically adjust the output of heat energy according to actual needs, thereby improving the response speed and flexibility of the system. By real-time monitoring of the temperature at the outlet of the mixing element 42, the system can accurately control the output of heat energy, avoid overheating or underheating, and optimize the use of heat energy. The valve control can quickly respond to temperature changes, ensuring that the temperature of the circulating water in the heat network is stable within the optimal range, thereby improving the efficiency of heating.

[0063] That is to say, the detection element is electrically connected to the control valve, and the detection element can transmit the monitored temperature information to the control valve in real time. The control valve adjusts its opening according to the information, thereby controlling the amount of heat energy discharged from the output port 32.
