[0004] To solve the above-mentioned technical problems, this application is implemented as follows: This application provides a hydraulically driven integrated heat pump device, which includes: a load-bearing component, a first heat exchange component, a turbine component, a screw compressor, and a second heat exchange component.

[0005] Optionally, the first heat exchange assembly includes a heat exchange shell and a plurality of heat exchange plates; Multiple heat exchange plates are disposed in the heat exchange shell and are spaced apart. The heat exchange shell is provided with a first opening and a second opening. Both the first opening and the second opening are in communication with the interior of the heat exchange shell. The first opening is in communication with the liquid inlet and the second opening is in communication with the turbine assembly. The heat exchanger plate has a liquid flow channel, a liquid inlet opening, and a liquid outlet opening. The liquid inlet opening and the liquid outlet opening are both connected to the liquid flow channel. The liquid flow channel is used to flow the heat exchange liquid. The liquid inlet openings of the plurality of heat exchanger plates are all connected to the second heat exchange assembly, and the liquid outlet openings of the plurality of heat exchanger plates are all connected to the screw compressor.

[0006] Optionally, the hydraulically driven heat exchange integrated heat pump device further includes a first flow guide, the first flow guide is a hollow structure, and the first flow guide is provided with a first flow guide port and a second flow guide port, the second flow guide port is connected to the first opening, and the first flow guide port is connected to the liquid inlet. Along the direction from the first flow guide to the second flow guide, the flow area of ​​the first flow guide gradually decreases.

[0007] Optionally, the two opposite side walls of the first guide member along the width direction of the flow channel are in contact with the channel wall of the flow channel.

[0008] Optionally, the hydraulically driven heat exchange integrated heat pump device further includes a second flow guide; The second guide is a hollow structure, and the second guide is provided with a third guide port and a fourth guide port. The third guide port is connected to the second opening, and the fourth guide port is connected to the turbine assembly. Along the direction from the third guide port to the fourth guide port, the flow area of ​​the second guide member gradually decreases.

[0009] Optionally, the heat exchange shell contacts the bottom of the flow channel, the height of the heat exchange shell is less than the depth of the flow channel, the depth of the flow channel is the distance from the opening of the flow channel to the bottom of the flow channel, and the height of the heat exchange shell is the distance between the two opposite ends of the heat exchange shell in the depth direction of the flow channel.

[0010] Optionally, the heat exchange shell has opposing first and second sides along the width direction of the flow channel, the flow channel has a first channel wall facing the first side and a second channel wall facing the second side, a first gap between the first side and the first channel wall, and / or a second gap between the second side and the second channel wall.

[0011] Optionally, the hydraulically driven heat exchange integrated heat pump device further includes a first flow guide, the height of which is less than the depth of the flow channel, and the height of the first flow guide is the distance between the two opposite ends of the first flow guide in the depth direction of the flow channel.

[0012] Optionally, the turbine assembly is connected to a drive shaft, the wall of the flow channel is provided with a rotation hole, and the drive shaft passes through the rotation hole and is connected to the screw compressor.

[0013] Optionally, the turbine assembly includes a turbine housing and a turbine disk disposed inside the turbine housing. The turbine housing has an inlet and an outlet. The inlet is connected to the first heat exchange assembly, and the outlet is connected to a bent liquid outlet pipe, which is connected to the liquid outlet. The turbine disk is connected to one end of the drive shaft, the turbine disk is configured to drive the drive shaft to rotate, the inlet is configured to allow the liquid to be exchanged to flow in, so as to make the turbine disk rotate, and the outlet is configured to allow the liquid to be exchanged to flow out.

[0014] In this embodiment, since a flow channel is formed inside the supporting component, and the supporting component is provided with an inlet and an outlet, both of which are connected to the flow channel, the liquid to be heat-exchanged can flow into the flow channel from the inlet, then flow in the flow channel and out from the outlet. Since both the first heat exchange component and the turbine component are disposed in the flow channel, and are arranged sequentially from the inlet to the outlet, the liquid to be heat-exchanged flowing into the flow channel can sequentially pass through the first heat exchange component and the turbine component. That is, the liquid first flows through the first heat exchange component, where it exchanges heat with the heat exchange liquid, thus heating the heat exchange liquid. Then, the liquid flows through the turbine component, driving the turbine component to operate. Finally, the liquid flows out from the outlet, thus utilizing both the thermal and kinetic energy of the liquid. Since the screw compressor and the second heat exchange assembly are both located outside the supporting assembly, the turbine assembly is connected to the screw compressor, and the screw compressor is connected to both the second and first heat exchange assemblies. The second heat exchange assembly is connected to the first heat exchange assembly. Therefore, when the turbine assembly is driven to operate by the liquid to be heat exchanged, the turbine assembly can drive the screw compressor to operate. That is, after the liquid to be heat exchanged exchanges heat with the heat exchange liquid in the first heat exchange assembly, the heat exchange liquid can flow into the screw compressor, and the screw compressor will be driven to operate by the turbine assembly, so that the screw compressor can compress the heat exchange liquid after heat exchange. The compressed heat exchange liquid flows into the second heat exchange assembly and exchanges heat in the second heat exchange assembly. Then, the heat exchange liquid flows out from the second heat exchange assembly and flows back into the first heat exchange assembly for heat exchange, realizing the circulation of the heat exchange liquid. That is, in the embodiments of this application, by setting a first heat exchange component, a turbine component, a screw compressor and a second heat exchange component, it is equivalent to enabling the liquid to be heat exchanged to exchange heat with the first heat exchange component, so that the thermal energy of the liquid to be heat exchanged is utilized. Then the liquid to be heat exchanged drives the turbine component to operate, and the turbine component drives the screw compressor to operate, so that the kinetic energy of the liquid to be heat exchanged is utilized, thereby improving the energy recovery efficiency of the liquid to be heat exchanged.

[0021] This application provides a hydraulically driven integrated heat pump device, such as... Figure 1 As shown, the hydraulically driven heat exchange integrated heat pump device includes: a load-bearing component 10, a first heat exchange component 20, a turbine component 30, a screw compressor 40, and a second heat exchange component 50.

[0022] The support assembly 10 has a flow channel 101 inside, and the support assembly 10 has a liquid inlet 102 and a liquid outlet 103, both of which are connected to the flow channel 101. The first heat exchange assembly 20 and the turbine assembly 30 are both disposed in the flow channel 101, and are arranged sequentially along the direction from the liquid inlet 102 to the liquid outlet 103. The screw compressor 40 and the second heat exchange assembly 50 are both disposed outside the support assembly 10. The turbine assembly 30 and the screw compressor 40 are connected in series. The compressor 40 is connected to the second heat exchange assembly 50 and the first heat exchange assembly 20 respectively. The second heat exchange assembly 50 is connected to the first heat exchange assembly 20. A heat exchange liquid flows in the first heat exchange assembly 20. When the liquid to be heat exchanged flows into the inlet 102, the liquid to be heat exchanged exchanges heat with the heat exchange liquid in the first heat exchange assembly 20. The liquid to be heat exchanged flows through the turbine assembly 30 to drive the turbine assembly 30 to operate. The turbine assembly 30 drives the screw compressor 40 to operate. The liquid to be heat exchanged flows out from the outlet 103.

[0023] In this embodiment of the application, since a flow channel 101 is formed inside the support component 10, and the support component 10 is provided with a liquid inlet 102 and a liquid outlet 103, both of which are connected to the flow channel 101, the liquid to be heat exchanged can flow into the flow channel 101 from the liquid inlet 102, and then the liquid to be heat exchanged flows in the flow channel 101 and flows out from the liquid outlet 103. Since the first heat exchange component 20 and the turbine component 30 are both disposed in the flow channel 101, and the first heat exchange component 20 and the turbine component 30 are arranged sequentially along the direction from the liquid inlet 102 to the liquid outlet 103, the liquid to be heat exchanged flowing into the flow channel 101 can flow through the first heat exchange component 20 and the turbine component 30 in sequence. That is, the liquid to be heat exchanged first flows through the first heat exchange component 20, and the liquid to be heat exchanged with the heat exchange liquid in the first heat exchange component 20, so that the heat exchange liquid is heated. Then the liquid to be heat exchanged flows through the turbine component 30, and the liquid to be heat exchanged can drive the turbine component 30 to operate. Then the liquid to be heat exchanged flows out from the liquid outlet 103, so that the thermal energy and kinetic energy of the liquid to be heat exchanged are both utilized. Since the screw compressor 40 and the second heat exchange assembly 50 are both located outside the supporting assembly 10, the turbine assembly 30 is connected to the screw compressor 40, and the screw compressor 40 is connected to both the second heat exchange assembly 50 and the first heat exchange assembly 20. The second heat exchange assembly 50 is connected to the first heat exchange assembly 20. Therefore, when the turbine assembly 30 is driven to operate by the liquid to be heat exchanged, the turbine assembly 30 can drive the screw compressor 40 to operate. That is, after the liquid to be heat exchanged exchanges heat with the heat exchange liquid in the first heat exchange assembly 20, the heat exchange liquid after heat exchange can flow into the screw compressor 40, and the screw compressor 40 will be driven to operate by the turbine assembly 30, so that the screw compressor 40 can compress the heat exchange liquid after heat exchange. The compressed heat exchange liquid flows into the second heat exchange assembly 50 and exchanges heat in the second heat exchange assembly 50. Then, the heat exchange liquid after heat exchange flows out from the second heat exchange assembly 50, and the heat exchange liquid flows back into the first heat exchange assembly 20 for heat exchange, realizing the circulation of the heat exchange liquid. That is, in this embodiment of the application, by setting the first heat exchange component 20, the turbine component 30, the screw compressor 40 and the second heat exchange component 50, it is equivalent to making the liquid to be heat exchanged exchange heat with the first heat exchange component 20, so that the thermal energy of the liquid to be heat exchanged is utilized. Then the liquid to be heat exchanged drives the turbine component 30 to operate, and the turbine component 30 drives the screw compressor 40 to operate, so that the kinetic energy of the liquid to be heat exchanged is utilized, thereby improving the energy recovery efficiency of the liquid to be heat exchanged.

[0024] It should be noted that, in the embodiments of this application, the liquid to be exchanged for heat can be wastewater or reclaimed water. This embodiment of the application does not limit the specific application in this regard.

[0025] In addition, in this embodiment, the second heat exchange component 50 may have a first heat exchange channel and a second heat exchange channel. The heat exchange liquid flows in the first heat exchange channel, and the liquid to be heated flows in the second heat exchange channel. When the liquid to be heated flows in the flow tank 101, the heat exchange liquid in the first heat exchange component 20 exchanges heat with the liquid to be heated, so that the heat exchange liquid is heated. The heated heat exchange liquid flows into the screw compressor 40, and the screw compressor 40 is driven by the turbine assembly 30 to compress the heated heat exchange liquid, making it a high-temperature and high-pressure heat exchange liquid. The high-temperature and high-pressure heat exchange liquid flows into the first heat exchange channel of the second heat exchange component 50, and the liquid to be heated in the second heat exchange channel exchanges heat with the high-temperature and high-pressure heat exchange liquid in the first heat exchange channel, so that the liquid to be heated is heated. At the same time, the high-temperature and high-pressure heat exchange liquid cools down. The cooled heat exchange liquid flows back into the first heat exchange component 20 to exchange heat with the liquid to be heated.

[0026] Additionally, in the embodiments of this application, such as Figure 3 As shown, the first heat exchange component 20 may be provided with an inlet opening 221 and an outlet opening 222. The inlet opening 221 is connected to the first heat exchange channel of the second heat exchange component 50 through a first pipe 001. The outlet opening 222 of the first heat exchange component 20 is connected to the screw compressor 40 through a second pipe 002. The screw compressor 40 is connected to the second heat exchange component 50 through a third pipe 003. The first pipe 001 may be provided with an expansion valve 004 to adjust the flow rate of the heat exchange liquid flowing out of the first heat exchange channel.

[0027] Additionally, in some embodiments, such as Figure 2 As shown, the first heat exchange assembly 20 includes a heat exchange shell 21 and a plurality of heat exchange plates 22; the plurality of heat exchange plates 22 are all disposed in the heat exchange shell 21 and are spaced apart; the heat exchange shell 21 has a first opening 211 and a second opening 212, both of which are connected to the interior of the heat exchange shell 21; the first opening 211 is connected to the liquid inlet 102 and the second opening 212 is connected to the turbine assembly 30; the heat exchange plates 22 have a liquid flow channel, a liquid inlet opening 221 and a liquid outlet opening 222, both of which are connected to the liquid flow channel for flowing heat exchange liquid; the liquid inlet openings 221 of the plurality of heat exchange plates 22 are all connected to the second heat exchange assembly 50 and the liquid outlet openings 222 of the plurality of heat exchange plates 22 are all connected to the screw compressor 40.

[0028] Since multiple heat exchange plates 22 are disposed in the heat exchange shell 21 and are spaced apart, the first opening 211 and the second opening 212 are both connected to the interior of the heat exchange shell 21. The first opening 211 is connected to the liquid inlet 102 and the second opening 212 is connected to the turbine assembly 30. Therefore, once the liquid to be heat exchanged flows in from the liquid inlet 102, the liquid to be heat exchanged can flow into the heat exchange shell 21 through the first opening 211 while flowing in the flow channel 101. The spaced distribution of multiple heat exchange plates 22 can ensure that each heat exchange plate 22 is in contact with the liquid to be heat exchanged flowing into the heat exchange shell 21 to achieve heat exchange. Afterwards, the liquid to be heat exchanged flows out of the heat exchange shell 21 from the second opening 212 and flows to the turbine assembly 30. Since the heat exchanger 22 has a liquid flow channel, a liquid inlet 221 and a liquid outlet 222, and both the liquid inlet 221 and the liquid outlet 222 are connected to the liquid flow channel, the liquid inlet 221 of multiple heat exchangers 22 are connected to the second heat exchange assembly 50, and the liquid outlet 222 of multiple heat exchangers 22 are connected to the screw compressor 40, after the heat exchange liquid in each heat exchanger 22 exchanges heat with the liquid to be heated, the heat exchange liquid in each heat exchanger 22 can flow into the screw compressor 40 through the liquid outlet 222. After being compressed by the screw compressor 40 into a high-temperature and high-pressure heat exchange liquid, the high-temperature and high-pressure heat exchange liquid flows into the second heat exchange assembly 50 and exchanges heat with the liquid to be heated in the second heat exchange assembly 50. The high-temperature and high-pressure heat exchange liquid will then cool down. After cooling down, the heat exchange liquid flows out from the second heat exchange assembly 50 and flows into the heat exchanger 22 through the liquid inlet 221. By setting up a heat exchange shell 21 and multiple heat exchange plates 22, the heat exchange between the liquid to be exchanged and the heat exchange liquid in the flow tank 101 can be facilitated, thereby making it easier for the thermal energy of the liquid to be exchanged to be utilized.

[0029] It should be noted that the number of heat exchange fins 22 can be set according to actual needs. For example, the number of heat exchange fins 22 can be 3, or for another example, the number of heat exchange fins 22 can be 5. The specific number of heat exchange fins 22 is not limited in this embodiment.

[0030] In addition, in this embodiment, the heat exchange plate 22 can be a pillow plate type heat exchange plate. Of course, the heat exchange plate 22 can also be other types, and this embodiment does not limit it here.

[0031] Additionally, in the embodiments of this application, such as Figure 1 and Figure 3 As shown, the liquid outlet 222 of the heat exchange plate 22 is closer to the first opening 211 of the heat exchange shell 21 than the liquid inlet 221, so that the flow direction of the heat exchange liquid in the heat exchange plate 22 is opposite to the flow direction of the liquid to be heat exchanged in the heat exchange shell 21, which is beneficial to the heat exchange between the heat exchange liquid in the heat exchange plate 22 and the liquid to be heat exchanged.

[0032] Additionally, in some embodiments, such as Figure 1 and Figure 3As shown, the water-driven heat exchange integrated heat pump device also includes a first flow guide 60. The first flow guide 60 has a hollow structure and is provided with a first flow guide port 601 and a second flow guide port 602. The second flow guide port 602 is connected to the first opening 211, and the first flow guide port 601 is connected to the liquid inlet 102. Along the direction from the first flow guide port 601 to the second flow guide port 602, the flow area of ​​the first flow guide 60 gradually decreases.

[0033] Since the second guide port 602 is connected to the first opening 211, and the first guide port 601 is connected to the liquid inlet 102, the liquid to be heat-exchanged flowing into the flow channel 101 can flow to the first guide port 601. Then, the liquid to be heat-exchanged flows through the first guide member 60 and into the heat exchange shell 21. Since the flow area of ​​the first guide member 60 gradually decreases along the direction from the first guide port 601 to the second guide port 602, once the liquid to be heat-exchanged flows into the first guide member 60, the flow velocity of the liquid to be heat-exchanged will increase. This allows the liquid with a higher flow velocity to flow into the heat exchange shell 21 and exchange heat with the heat exchange liquid in the heat exchange plate 22. The liquid with a higher flow velocity flows out from the second opening 212 in the heat exchange shell 21, which is beneficial for the turbine assembly 30 to be driven and operated, and thus beneficial for the turbine assembly 30 to drive the screw compressor 40 to operate.

[0034] It should be noted that the first flow guide 60 can be a tubular structure. Of course, the first flow guide 60 can also be of other types. For example, the first flow guide 60 includes a first guide plate and a second guide plate, which are spaced apart along the width direction X of the flow channel 101. Both the first and second guide plates are inclined relative to the channel wall of the flow channel 101. The first end of the first guide plate and the first end of the second guide plate are both connected to the first opening 211 of the heat exchange shell 21. The second ends of both the first and second guide plates are far from the heat exchange shell 21, and the distance between the second ends of the first and second guide plates is greater than the distance between the first ends of the first and second guide plates. The specific structure of the first flow guide plate is not limited in this embodiment.

[0035] Additionally, in some embodiments, such as Figure 1As shown, the two opposite side walls of the first guide member 60 along the width direction X of the flow channel 101 contact the channel wall of the flow channel 101. With this arrangement, once the heat-exchange liquid flowing into the flow channel 101 reaches the first guide port 601 of the first guide member 60, a larger amount of the heat-exchange liquid can flow into the first guide member 60. This prevents the heat-exchange liquid from flowing away from the first guide member 60 along the width direction X of the flow channel 101, thus avoiding the waste of energy caused by some fluid in the flow channel 101 not flowing into the first guide member 60. Furthermore, the larger amount of heat-exchange liquid flowing into the first guide member 60 allows more of the heat-exchange liquid to flow out from the second opening 212 of the heat exchange shell 21 and through the turbine assembly 30, which is beneficial for the turbine assembly 30 to be driven by the heat-exchange liquid.

[0036] Additionally, in some embodiments, such as Figure 1 As shown, the water-driven heat exchange integrated heat pump device also includes a second flow guide 70; the second flow guide 70 has a hollow structure and is provided with a third flow guide port 701 and a fourth flow guide port 702. The third flow guide port 701 is connected to the second opening 212, and the fourth flow guide port 702 is connected to the turbine assembly 30; along the direction from the third flow guide port 701 to the fourth flow guide port 702, the flow area of ​​the second flow guide 70 gradually decreases.

[0037] Since the third guide port 701 is connected to the second opening 212 and the fourth guide port 702 is connected to the turbine assembly 30, the liquid to be exchanged flowing into the heat exchange shell 21 can flow to the second opening 212, and then flow through the second guide member 70 and to the turbine assembly 30. Because the flow area of ​​the second guide member 70 gradually decreases along the direction from the third guide port 701 to the fourth guide port 702, once the liquid to be exchanged flows into the second guide member 70, the flow velocity of the liquid will increase, allowing the high-velocity liquid to flow to the turbine assembly 30, which is beneficial for the turbine assembly 30 to be driven and operated, and thus beneficial for the turbine assembly 30 to drive the screw compressor 40 to operate. Furthermore, based on the first guide member 60, the second guide member 70 can further increase the flow velocity of the liquid to be exchanged flowing out of the heat exchange shell 21, further facilitating the turbine assembly 30 to be driven and operated by the high-velocity liquid.

[0038] It should be noted that the second guide member 70 can be a tubular structure, that is, the second guide member 70 is equivalent to a guide tube, and the cross-sectional area inside the guide tube gradually decreases. Furthermore, when the second guide member 70 is a guide tube, it ensures that all the liquid to be exchanged flowing out of the heat exchange shell 21 flows through the second guide member 70 and then to the turbine assembly 30, which is beneficial for the turbine assembly 30 to be driven and operated. Of course, the second guide member 70 can also be of other types; for example, the second guide member 70 can be formed by multiple guide plates. The specific structure of the second guide plate is not limited in this embodiment.

[0039] In addition, in this embodiment, the flow area of ​​the third flow port 701 can be equal to the flow area of ​​the second opening 212, and the third flow port 701 can be directly connected to the second opening 212.

[0040] Additionally, in some embodiments, such as Figure 2 As shown, the heat exchange shell 21 is in contact with the bottom of the flow channel 101. The height of the heat exchange shell 21 is less than the depth of the flow channel 101. The depth of the flow channel 101 is the distance from the opening of the flow channel 101 to the bottom of the flow channel 101. The height of the heat exchange shell 21 is the distance between the two opposite ends of the heat exchange shell 21 in the depth direction Y of the flow channel 101.

[0041] With this configuration, once the liquid to be exchanged flows into the heat exchange tank, when it flows to the heat exchange shell 21, a gap between the heat exchange shell 21 and the bottom of the flow channel 101 can be avoided, preventing the liquid from flowing through this gap and reducing the amount of liquid flowing into the heat exchange shell 21. Furthermore, since the height of the heat exchange shell 21 is less than the depth of the flow channel 101, if there is too much liquid in the flow channel 101, the liquid can overflow from the top of the outer wall of the heat exchange shell 21 and flow to the outlet 103, preventing the liquid from overflowing outside the flow channel 101.

[0042] Additionally, in some embodiments, such as Figure 1 and Figure 2 As shown, the heat exchange shell 21 has a first side surface 2101 and a second side surface 2102 opposite to each other along the width direction X of the flow channel 101. The flow channel 101 has a first channel wall 1011 facing the first side surface 2101 and a second channel wall 1012 facing the second side surface 2102. There is a first gap between the first side surface 2101 and the first channel wall 1011, and / or there is a second gap between the second side surface 2102 and the second channel wall 1012.

[0043] When there is a first gap between the first side surface 2101 and the first tank wall 1011, if there is too much heat exchange liquid in the flow tank 101, the heat exchange liquid can flow through the first gap between the first side surface 2101 and the first tank wall 1011 when it flows to the heat exchange shell 21. This allows the excess heat exchange liquid to flow to the outlet 103, preventing the heat exchange liquid from overflowing to the outside of the flow tank 101. Similarly, when there is a second gap between the second side surface 2102 and the second tank wall 1012, if there is too much heat exchange liquid in the flow tank 101, the heat exchange liquid can flow through the second gap between the second side surface 2102 and the second tank wall 1012 when it flows to the heat exchange shell 21. This allows the excess heat exchange liquid to flow to the outlet 103, preventing the heat exchange liquid from overflowing to the outside of the flow tank 101.

[0044] It should be noted that, in the embodiments of this application, there may be only a first gap between the first side surface 2101 and the second groove wall 1012, or there may be only a second gap between the second side surface 2102 and the second groove wall 1012. Of course, there may also be a first gap between the first side surface 2101 and the second groove wall 1012, and a second gap between the second side surface 2102 and the second groove wall 1012. This embodiment of the application does not limit the scope of the application in this regard.

[0045] Additionally, in some embodiments, such as Figure 1 and Figure 2 As shown, the hydraulically driven heat exchange integrated heat pump device also includes a first guide member 60. The height of the first guide member 60 is less than the depth of the flow channel 101. The height of the first guide member 60 is the distance between the two opposite ends of the first guide member 60 in the depth direction Y of the flow channel 101.

[0046] With this configuration, if there is too much heat exchange liquid in the flow tank 101, when the heat exchange liquid flows to the first guide member 60, it can overflow from the first guide member 60. That is, the heat exchange liquid can overturn the first guide member 60, avoiding the problem that the height of the first guide member 60 is equal to the height of the flow tank 101, which could cause the heat exchange liquid to overflow to the outside of the flow tank 101 due to being blocked by the first guide member 60.

[0047] It should be noted that, in this embodiment of the application, the height of the first guide member 60 can be less than the depth of the flow channel 101, and there is a first gap between the first side 2101 of the heat exchange shell 21 and the first channel wall 1011, and / or, there is a second gap between the second side 2102 of the heat exchange shell 21 and the second channel wall 1012. Thus, if there is a large amount of liquid to be exchanged in the flow channel 101, the liquid to be exchanged can overflow from the first guide member 60 to the first gap and / or the second gap, ensuring that the excess liquid to be exchanged flows to the outlet 103.

[0048] Additionally, in some embodiments, such as Figure 1 and Figure 4 As shown, the turbine assembly 30 is connected to a drive shaft 80, and the wall of the flow channel 101 is provided with a rotation hole. The drive shaft 80 passes through the rotation hole and is connected to the screw compressor 40. This arrangement facilitates the connection between the turbine assembly 30 and the screw compressor 40, and thus, when the turbine assembly 30 is running, it facilitates the turbine assembly 30 to drive the screw compressor 40.

[0049] It should be noted that a bearing can be installed inside the rotating hole, and the drive shaft 80 passes through the bearing to facilitate the rotation of the drive shaft 80 relative to the rotating hole.

[0050] Additionally, in some embodiments, such as Figure 4 As shown, the turbine assembly 30 includes a turbine housing 31 and a turbine disk (not shown) disposed inside the turbine housing 31. The turbine housing 31 has an inlet 311 and an outlet 312. The inlet 311 is connected to the first heat exchange assembly 20, and the outlet 312 is connected to a bent liquid outlet pipe 313, which is connected to the liquid outlet 103. The turbine disk is connected to one end of the drive shaft 80 and is configured to drive the drive shaft 80 to rotate. The inlet 311 is configured to allow the liquid to be exchanged to flow in, so as to make the turbine disk rotate, and the outlet 312 is configured to allow the liquid to be exchanged to flow out.

[0051] Since the inlet 311 is connected to the first heat exchange component 20, and the outlet 312 is connected to a bent liquid outlet pipe 313, which is connected to the liquid outlet 103, once the flow channel 101 is filled with the liquid to be exchanged, the liquid can flow into the inlet 311 of the turbine housing 31 and into the turbine housing 31. The liquid can then drive the turbine disk in the turbine housing 31 to rotate. Afterward, the liquid can flow from the outlet 312 of the turbine housing 31 into the liquid outlet pipe 313. The bend in the liquid outlet pipe 313 slows down the flow rate of the liquid leaving the turbine housing 31, thus allowing the turbine disk in the turbine housing 31 to be driven and operated more effectively by the liquid. In addition, the turbine disk is connected to one end of the drive shaft 80. When the turbine disk is driven to rotate by the liquid to be exchanged, the turbine disk can drive the drive shaft 80 to rotate, thereby driving the screw compressor 40 to operate. This allows the turbine assembly 30 to drive the screw compressor 40 to operate.

[0052] It should be noted that in this embodiment, the turbine assembly 30 can be a Tesla turbine. Of course, the turbine assembly 30 can also be other types of turbines, such as a bladed turbine, as long as the turbine assembly 30 can be driven by the liquid to be exchanged. This embodiment does not limit the specific type of turbine. The Tesla turbine is a bladeless boundary layer turbine that relies on fluid viscosity to generate traction between closely packed smooth discs to drive the rotor. Compared with traditional bladed turbines, it has significant advantages such as simple structure, wear resistance, stronger adaptability to turbid fluids containing particles or fibers (such as unfiltered wastewater), and less clogging, making it very suitable as an energy recovery device in wastewater or reclaimed water pipelines.

[0053] In addition, in the embodiments of this application, when the hydraulically driven heat exchange integrated heat pump device includes a second guide member 70, the fourth guide port 702 of the second guide member 70 is connected to the inlet 311 of the turbine housing 31.

[0054] Additionally, in the embodiments of this application, such as Figure 5 As shown, the water-driven heat exchange integrated heat pump device may also include a fixed shell 90 and a liquid inlet communicating with the fixed shell 90. The fixed shell 90 has a receiving cavity, and the first heat exchange component 20 is disposed in the receiving cavity. Thus, the liquid flowing in the flow channel 101 can flow to the first heat exchange component 20 through the liquid inlet. The fixed shell 90 can protect the first heat exchange component 20 and prevent the first heat exchange component 20 from being easily damaged by external impacts.
