Description

Technical Field

[0001] The present application relates to the technical field of heat exchange equipment, and in particular to a heat network drain cooler. Background Art

[0002] A cooler is a type of heat exchange equipment, mainly used to cool fluids. It can exchange heat through partition, hybrid, heat storage and other methods, and is usually composed of two parts: an external shell and an internal cooler body. In the waste heat utilization project of a power plant, the temperature of the hot water network of the power plant is relatively high, and a cooler is needed to reduce the temperature of the hot water network.

[0003] In the prior art, the heat network drain cooler includes a tank body and a heat exchange pipe. The tank body is connected to a water inlet pipe and a drain pipe respectively. There are multiple heat exchange pipes, and the multiple heat exchange pipes are all arranged in the tank body. In the working state, hot water (which can be domestic water, etc.) is added to the tank body through the water inlet pipe, and then hot network water is introduced into the tank body through the heat exchange pipe. When the hot network water flows through the heat exchange pipe, the heat in it is transferred to the hot water in the tank body by the pipe wall of the heat exchange pipe, so that heat is exchanged between the hot network water and the hot water, the temperature of the hot network water is reduced, and the purpose of waste heat utilization is achieved.

[0004] However, in this type of hot network drain cooler, the hot network water is introduced into the tank body through the heat exchange tube. In order to improve the heat exchange effect between the hot network water and the hot water, the heat exchange tube needs to be manufactured to a certain length to increase the contact area between the hot network water and the hot water, thereby improving the heat exchange effect; this means that the tank body needs to be adapted to the length of the heat exchange tube during manufacturing to ensure that the heat exchange tube has sufficient installation space, which not only increases the floor space of the tank body, but also the overall manufacturing cost is relatively high, so further improvement is needed. Summary of the invention

[0005] In order to reduce the space occupancy and manufacturing cost of the tank body, the present application provides a heat network drain cooler.

[0006] The present application provides a heat network drain cooler adopting the following technical solution:

[0007] A heat network drain cooler comprises a tank body, a cover plate and a heat exchange plate group, wherein the tank body is respectively connected with a first water inlet pipe and a first drain pipe, the tank body has a mounting port, and the cover plate is arranged on the tank body for opening and closing the mounting port; the heat exchange plate group is arranged on the cover plate and located in the tank body, and a plurality of heat exchange plate groups are arranged along the length direction of the tank body, and a heat exchange cavity is arranged in each of the heat exchange plate groups; the cover plate is respectively connected with a second water inlet pipe and a second drain pipe, the second water inlet pipe and the second drain pipe are both connected with the heat exchange cavities of all the heat exchange plate groups, and the height of the second water inlet pipe is lower than the height of the second drain pipe.

[0008] By adopting the above technical scheme, through the setting of the heat exchange plate group, when the heat network water is heat exchanged, the heat exchange water is added into the tank body through the first water inlet pipe, and the heat network water is introduced through the second water inlet pipe. The heat of the hot network water is transferred to the heat exchange water in the tank body by the plate wall of the heat exchange plate group, so that the heat exchange between the hot network water and the heat exchange water is carried out, the temperature of the hot network water is reduced, and the purpose of waste heat utilization is achieved; the setting of multiple heat exchange plate groups forms multiple heat exchange cavities, increases the contact area between the hot network water and the heat exchange water (indirect contact), and thus improves the heat exchange effect; at the same time, the heat exchange cavity of the heat exchange plate group is used for heat exchange, avoiding the form of heat exchange by heat exchange tubes, so that the length of the tank body can be controlled within a certain range (no need to adapt the length of the heat exchange tubes), thereby reducing the space occupancy rate and manufacturing cost of the tank body.

[0009] Optionally, two guide strips are provided in the heat exchange chamber, and both of the guide strips are spirally arranged. The inner wall of the heat exchange chamber and the two guide strips are combined to form a heat exchange channel for water flowing through the heating network. The second water inlet pipe is connected to one end of the heat exchange channel, and the second drain pipe is connected to the other end of the heat exchange channel.

[0010] By adopting the above-mentioned technical scheme, through the setting of the guide strips, the two guide strips are spirally shaped and combined to form a spiral heat exchange flow channel. After the hot network water is pumped into the heat exchange chamber through the second water inlet pipe, it can flow into the heat exchange flow channel, thereby transferring heat to the hot water, and then discharged outwardly through the second drain pipe. The heat exchange flow channel can prolong the residence time of the hot network water in the heat exchange chamber, thereby improving the heat exchange effect.

[0011] Optionally, the cover plate is rotatably installed with a rotating shaft, and the rotating shaft passes through all the heat exchange plate groups in sequence, and two adjacent heat exchange plate groups are spaced apart to form a heat exchange zone; a plurality of pushing frames for pushing hot water for water exchange are arranged in the heat exchange zone, and the plurality of pushing frames are spaced apart around the central axis of the rotating shaft, and each of the pushing frames is slidably installed in the heat exchange zone and can be displaced radially along the rotating shaft; the rotating shaft is respectively provided with a first driving member and a second driving member, and the first driving member is used to drive the rotating shaft to rotate, and when the rotating shaft rotates, the second driving member drives all the pushing frames to displace synchronously.

[0012] By adopting the above technical scheme, through the arrangement of the heat exchange zone and the push frame, the heat exchange zone formed by the interval arrangement between two adjacent heat exchange plate groups is provided for hot water to flow in, thereby increasing the contact area between the hot water and the heat network water; during the heat exchange process, the first driving member drives the rotating shaft to rotate, and the rotating shaft drives all the push frames to move radially along the rotating shaft through the second driving member. The displaced push frame can push the hot water (the hot water that absorbs heat) after heat exchange in the heat exchange zone out of the heat exchange zone. At the same time, the hot water (the hot water that does not absorb heat) located outside the heat exchange zone can flow into the heat exchange zone, thereby increasing the flow rate of the hot water, thereby improving the heat exchange effect between the heat network water and the hot water.

[0013] Optionally, the second driving member includes an eccentric rod and a connecting rod, the eccentric rod is located in the heat exchange area, two ends of the eccentric rod are respectively connected to the rotating shaft and are eccentrically arranged between the rotating shaft; the number of the connecting rods is arranged corresponding to the number of the pushing frames, one end of each of the connecting rods is hinged to the corresponding pushing frame, and the other end is hinged to the eccentric rod.

[0014] By adopting the above technical solution, through the arrangement of the eccentric rod and the connecting rod, when the rotating shaft rotates, the eccentric rod is driven to revolve around the central axis of the rotating shaft, thereby pulling or pushing all the connecting rods to drive all the pushing frames to move; one end of all the connecting rods is hinged to the eccentric rod, which means that when the eccentric rod revolves around the central axis of the rotating shaft, when the eccentric rod drives a certain pushing frame to move away from the central axis of the rotating shaft, at least part of the pushing frames are moved toward the central axis of the rotating shaft, and the pushing frames that move outward can push the hot water in the heat exchange zone out of the heat exchange zone, and the pushing frames that move inward can introduce the hot water outside the heat exchange zone into the heat exchange zone, thereby improving the flow effect of the hot water inside and outside the heat exchange zone.

[0015] Optionally, the number of pushing frames in two adjacent heat exchange zones is set correspondingly, and the displacement direction of the pushing frame and the corresponding pushing frame in the adjacent heat exchange zone is opposite. When the pushing frame displaces away from the rotating shaft, the corresponding pushing frame in the adjacent heat exchange zone displaces closer to the rotating shaft.

[0016] By adopting the above-mentioned technical scheme, the displacement directions between the two pushing frames corresponding to the two adjacent heat exchange zones are set to be opposite, so that when the pushing frame is displaced away from the rotating shaft, the pushing frame corresponding thereto in the adjacent heat exchange zone is displaced toward the rotating shaft, and the hot water at the corresponding positions of the two adjacent heat exchange zones enters and exits one by one, thereby forming a vortex on the outside of the heat exchange zone, thereby improving the stirring effect on the hot water, and further improving the heat exchange effect between the hot network water and the hot water.

[0017] Optionally, the heat exchange flow channel includes a first flow area, a second flow area and a reversing area, the second water inlet pipe is connected to the first flow area, the second drain pipe is connected to the second flow area, and one end of the first flow area away from the second water inlet pipe and one end of the second flow area away from the second drain pipe are both connected to the reversing area; the first driving member includes a mounting seat and an impeller, the mounting seat is arranged in the reversing area, a mounting cavity is provided in the mounting seat, and an outer wall of the mounting seat is respectively provided with a water inlet and a drain port connected to the mounting cavity, the water inlet is connected to the first flow area, and the drain port is connected to the second flow area; the impeller is arranged in the mounting cavity, and the rotating shaft penetrates into the mounting cavity and is connected and fixed to the impeller.

[0018] By adopting the above technical solution and arranging the mounting seat and the impeller, the hot network water passes through the second water inlet pipe heat exchange plate group, and then passes through the first flow area, the water inlet of the mounting seat, the mounting cavity, the drain port of the mounting seat and the second flow area in sequence, and then is discharged outward through the second drain pipe; when the hot network water passes through the mounting cavity, it pushes the impeller, thereby driving the rotating shaft to rotate, and then driving the push frame to move, which is energy-saving and environmentally friendly.

[0019] Optionally, two guide strips are provided on the side wall of the mounting seat located at the water inlet, and the two guide strips are combined to form a guide channel, the inlet end of the guide channel is connected to the first flow area, the outlet end of the guide channel is connected to the water inlet, and the inlet end of the guide channel gradually narrows toward the outlet end opening of the guide channel.

[0020] By adopting the above-mentioned technical solution and setting up the guide flow channel, the opening of the inlet end of the guide flow channel gradually narrows toward the outlet end of the guide flow channel, so that after the hot network water enters the guide flow channel, the guide flow channel can form a certain pressurization effect on the hot network water, so that the hot network water has sufficient power to drive the impeller to rotate, thereby driving the push frame to move.

[0021] Optionally, each of the guide strips is provided with a heat dissipation channel, which is spirally arranged along the curvature of the guide strip. Two opposite plate surfaces of the heat exchange plate group are provided with a plurality of connecting holes, and each of the connecting holes is connected to the heat dissipation channel for hot water to flow in or out.

[0022] By adopting the above technical solution, through the setting of the heat dissipation flow channel and the connecting hole, after the hot network water flows through the heat exchange flow channel, part of the heat in the hot network water is transferred to the guide strip, and after the hot water in the tank enters the heat dissipation flow channel through the connecting hole, heat is exchanged with the inner wall of the heat dissipation flow channel, thereby absorbing the heat in the guide strip, thereby improving the heat exchange effect of the overall structure.

[0023] Optionally, the heat dissipation channel is slidably installed with a push bar, the shape of which is adapted to the shape of the heat dissipation channel; a push member is provided between the push bar and the rotating shaft, and when the rotating shaft rotates, the push member drives the push bar to slide back and forth along the thickness direction of the heat exchange plate group.

[0024] By adopting the above technical solution and arranging the pushing strip and the pushing member, when the rotating shaft rotates, the pushing member drives the pushing strip to slide back and forth along the thickness direction of the heat exchange plate group, and the reciprocatingly sliding pushing strip can push out the hot water in the heat dissipation channel. At the same time, after the hot water in the heat dissipation channel is pushed out, the external hot water flows back into the heat dissipation channel to form a "breathing" heat dissipation channel, so as to continuously exchange heat with the guide strip, thereby greatly improving the heat exchange effect of the overall structure.

[0025] Optionally, an embedding hole connected to the heat dissipation channel is opened on the inner wall of the heat exchange channel, a first thermal conductive bar is embedded in the embedding hole, a second thermal conductive bar is embedded on the surface of the push bar, and the first thermal conductive bar and the second thermal conductive bar are abutted against each other.

[0026] By adopting the above technical solution and arranging the first heat-conducting strip and the second heat-conducting strip, the heat conduction effect between the guide strip and the push strip is improved.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. Through the setting of the heat exchange plate group, when the heat network water is exchanged with heat, the heat exchange water is added into the tank body through the first water inlet pipe, and the heat network water is introduced through the second water inlet pipe. The heat of the heat network water can enter the heat exchange cavity of all heat exchange plate groups, and the heat of the heat network water is transferred to the heat exchange water in the tank body by the plate wall of the heat exchange plate group, so that the heat exchange between the heat network water and the heat exchange water is carried out, the temperature of the heat network water is reduced, and the purpose of waste heat utilization is achieved; the setting of multiple heat exchange plate groups forms multiple heat exchange cavities, which increases the contact area between the heat network water and the heat exchange water (indirect contact), thereby improving the heat exchange effect; at the same time, the heat exchange cavity of the heat exchange plate group is used for heat exchange, avoiding the form of heat exchange using heat exchange tubes, so that the length of the tank body can be controlled within a certain range (no need to adapt the length of the heat exchange tube), thereby reducing the space occupancy rate and manufacturing cost of the tank body;

[0029] 2. Through the setting of the guide strips, the two guide strips are spiral and combined to form a spiral heat exchange flow channel. After the hot network water is pumped into the heat exchange cavity from the second water inlet pipe, it can flow into the heat exchange flow channel, thereby transferring heat to the hot water, and then discharged outward from the second drain pipe. The heat exchange flow channel can prolong the retention time of the hot network water in the heat exchange cavity, thereby improving the heat exchange effect;

[0030] 3. Through the setting of the pushing strip and the pushing member, when the rotating shaft rotates, the pushing member drives the pushing strip to slide back and forth along the thickness direction of the heat exchange plate group, and the reciprocating sliding pushing strip can push out the hot water in the heat dissipation channel. At the same time, after the hot water in the heat dissipation channel is pushed out, the external hot water flows back into the heat dissipation channel to form a "breathing" heat dissipation channel, so as to continuously exchange heat with the guide strip, thereby greatly improving the heat exchange effect of the overall structure.

[0078] The mounting seat 71 is installed with two guide strips 714, one end of the two guide strips 714 is fixedly installed on the outer wall of the mounting seat 71 at the water inlet 712, and the other end is fixedly installed on the inner wall of the first flow area 51, and the two guide strips 714 are combined to form a guide channel 715, the inlet end of the guide channel 715 is connected to the first flow area 51, and the outlet end of the guide channel 715 is connected to the water inlet 712, and the inlet end of the guide channel 715 gradually narrows toward the outlet end opening of the guide channel 715.

[0080] Embodiment 5:

[0081] The embodiment of the present application discloses a heat network drain cooler.

[0082] Reference Fig.12 The difference between the heat network drain cooler disclosed in the embodiment of the present application and the embodiment 3 is that:

[0083] In this embodiment, heat dissipation channels 41 are provided in the two guide bars 4, and the heat dissipation channels 41 are spirally arranged along the curvature of the guide bars 4.

After the hot water in the tank body 1 enters the heat dissipation channel 41 through the connecting hole 33, it exchanges heat with the inner wall of the heat dissipation channel 41, thereby absorbing the heat in the guide strip 4 and improving the heat exchange effect of the overall structure.

[0085] Embodiment 6:

[0086] The embodiment of the present application discloses a heat network drain cooler.

[0087] Reference Fig.13 , Fig.14 The difference between the heat network drain cooler disclosed in the embodiment of the present application and the embodiment 5 is that:

[0088] In this embodiment, a push bar 42 is slidably installed in the heat dissipation channel 41, and the shape of the push bar 42 is adapted to the shape of the heat dissipation channel 41 (that is, the push bar 42 is spirally shaped). A push member 9 is arranged between the push bar 42 and the rotating shaft 23. When the rotating shaft 23 rotates, the push member 9 drives the push bar 42 to slide back and forth along the thickness direction of the heat exchange plate group 3.

[0089] Reference Fig.13 , Fig.14 The pushing member 9 includes a pushing block 91 and a return spring 92. A connecting rod 911 is fixedly installed on the side wall of the pushing strip 42. One end of the connecting rod 911 is fixedly connected to the side wall of the pushing strip 42, and the other end extends to the heat exchange area 32 and is fixedly connected to the pushing block 91. The side wall of the pushing block 91 away from the connecting rod 911 has a pushing surface 912 for the connecting strip 83 to push; the return spring 92 is installed in the heat dissipation channel 41, one end of the return spring 92 is fixedly connected to the pushing strip 42, and the other end is fixedly connected to the inner wall of the heat dissipation channel 41. When the rotating shaft 23 drives the connecting strip 83 to rotate, and the connecting strip 83 pushes the pushing block 91 through the pushing surface 912, the pushing block 91 pushes the pushing strip 42, and the return spring 92 is deformed and has elastic force. When the connecting strip 83 is separated from the pushing block 91, the return spring 92 recovers its deformation.

[0090] Reference Fig.13 , Fig.14 The inner wall of the heat exchange channel 5 is provided with an embedding hole connected to the heat dissipation channel 41, and a first heat conducting bar 54 is embedded in the embedding hole. A plurality of first heat conducting bars 54 are arranged along the thickness direction of the heat exchange plate group 3, and a second heat conducting bar 43 is embedded in the pushing bar 42, and the first heat conducting bar 54 and the second heat conducting bar 43 are abutted against each other.

[0091] The implementation principle of Example 6 of the present application is as follows: when the rotating shaft 23 rotates, the pushing member 9 drives the pushing strip 42 to slide back and forth along the thickness direction of the heat exchange plate group 3, and the reciprocatingly sliding pushing strip 42 can push out the hot water in the heat exchange channel 41. At the same time, after the hot water in the heat exchange channel 41 is pushed out, the external hot water flows into the heat exchange channel 41 again, forming a "breathing" heat exchange channel 41, so as to continuously exchange heat with the guide strip 4, thereby greatly improving the heat exchange effect of the overall structure.

[0092] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
