Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat exchange equipment, in particular to a heat exchange equipment for a geothermal system. BACKGROUND

[0002] The working principle of the heat exchange equipment of the geothermal system is to utilize the heat of geothermal energy, and transmit the heat to a heating system or a domestic hot water system through a heat exchanger. The heat exchanger is an energy-saving equipment for realizing heat transfer between materials between two or more than two fluids at different temperatures. The heat exchange equipment is extremely common in the industrial fields of chemical industry, petroleum, aerospace and energy.

[0003] Among them, since the hot waste water inlet of the heat exchanger is fixed at a single position, this leads to the stable injection of the water flow of the waste water into the inside of the heat exchange equipment from top to bottom. When the stable water flow passes the outer wall of the clean water pipe for a long time, the impurities in the waste water will be accumulated at the top of the pipe, and the accumulated impurities will form an insulating layer, which indirectly reduces the heat conduction efficiency of the clean water pipe. In view of the above problems, the following scheme is proposed. SUMMARY

[0004] To solve the above technical problems, the present application provides a heat exchange equipment for a geothermal system, which comprises an outer shell, a clear water inlet pipe connected through the side wall of the outer shell, a clear water outlet pipe connected through the end of the outer shell away from the clear water inlet pipe, a hot waste water inlet pipe connected through the side wall of the outer shell, and a hot waste water outlet pipe connected through the bottom of the outer shell, and further comprises: An isolation mechanism fixedly connected to the inner wall of the outer shell; A drainage mechanism fixedly connected to the inner wall of the outer shell; A separation mechanism fixedly connected to the bottom of the outer shell; Among them, the clear water enters the inside of the outer shell through the clear water inlet pipe, and is discharged outward from the clear water outlet pipe through the isolation mechanism, and the hot waste water enters the inside of the outer shell through the hot waste water inlet pipe, and heats the isolation mechanism and the internal clear water.

[0005] Preferably, the isolation mechanism comprises: An exchange assembly fixedly connected to the inner wall of the outer shell; An isolation assembly fixedly connected to the inner wall of the outer shell; Among them, the exchange assembly and the isolation assembly divide the inside of the outer shell into multiple layers of space, so that the hot waste water flows in a specific path when entering the inside of the outer shell.

[0006] Preferably, the drainage mechanism comprises: A rotating assembly fixedly connected to the inner wall of the outer shell; A flow assembly rotatably connected to the outer wall of the rotating assembly; The hot wastewater entering the pipe impacts the flow assembly, causing it to rotate along the outer wall of the rotating assembly.

[0007] Preferably, the separation mechanism includes: The interception component is fixedly connected to the bottom of the housing; The accumulated component is fixedly connected to the bottom of the intercepted component; When hot wastewater reaches the outer wall of the isolation unit from the drainage mechanism, it will be transferred to the rest of the isolation unit through the interception component.

[0008] Preferably, the heat exchange assembly includes a spacer ring 1 fixedly connected to the inner wall of the housing, a plurality of heat exchange tubes being connected through the side wall of the spacer ring 1, a spacer ring 2 being fixedly connected to the end of the plurality of heat exchange tubes away from the spacer ring 1, and a reinforcing plate being fixedly connected to the outer wall of the spacer ring 1. Among them, the outer wall of the second partition ring is fixedly connected to the inner wall of the outer shell, and the first partition ring and the second partition ring divide the outer shell into three spaces. When the clean water in the clean water inlet pipe reaches the position of the second partition ring, it will be transferred to the first partition ring through the heat exchange pipe and finally discharged outward from the clean water outlet pipe.

[0009] Preferably, the isolation assembly includes a partition plate one fixedly connected to the outer wall of the heat exchange tube, a partition plate two fixedly connected to the outer wall of the heat exchange tube, and a flow hole provided on the side wall of the partition plate two. Among them, partition ring one, partition plate two, partition plate one and partition ring two all divide the internal space of the shell, and the hot wastewater on the left and right sides of partition plate two can flow through the flow holes.

[0010] Preferably, the rotating assembly includes a fixed tube fixedly connected to the inner wall of the outer shell, a partition ring 1 fixedly connected to the side wall of the fixed tube, a flow port 1 opened on the side wall of the fixed tube, and a flow port 2 opened on the side wall of the fixed tube. The fixed pipe and the partition ring are both welded to the inner wall of the outer shell and form a sealed state. The hot wastewater inside the groove on the outer wall of the fixed pipe can only come into contact with the outer wall of the heat exchange pipe through the flow port.

[0011] Preferably, the flow assembly includes a rotating ring rotatably connected to the outer wall of a partition ring, an inclined blade fixedly connected to the side wall of the rotating ring, and a flow port three opened on the side wall of the rotating ring. The hot wastewater discharged downward through the inlet pipe will impact the inclined blades, which in turn drive the rotating ring to rotate along the outer wall of the first partition ring.

[0012] Preferably, the interception component includes a separation box that is connected through to the bottom of the outer shell, and a plurality of inclined plates are fixedly connected to the inner wall of the separation box, with flow through holes opened on the side walls of the plurality of inclined plates.

[0013] Preferably, the accumulation assembly comprises a storage tank fixedly connected to the bottom of the separation tank, and an inclined plate is fixedly connected to the side wall of the storage tank. The second inclined plate will intercept the impurities in the hot wastewater and accumulate in the inside of the interception assembly, and finally enter the inside of the storage tank through the intercommunication hole.

[0014] The present application has the following advantages: (1) The present application is aimed at the problem of single hot wastewater inlet, which leads to the accumulation of impurities on the top of the outer wall of the heat exchange pipe and affects the heat conductivity. Since the rotating ring is always in a rotating state during operation, the four flow-through ports three will circulate through the outer wall of the flow-through port one. During the process of the flow-through port three passing through the flow-through port one, the overlapping position of the flow-through port three and the flow-through port one changes constantly, which makes the position of the hot wastewater entering change constantly. Through the application of the above-mentioned assembly, since the heat exchange pipes are all cylindrical, when the wastewater passes through the position of the heat exchange pipe, the wastewater will impact the outer wall of the heat exchange pipe. If the outer wall of the heat exchange pipe is sticky with impurities, under the condition that the water inlet position changes constantly, the multi-angle wastewater impact will effectively prevent the sticking of impurities and reduce the generation efficiency of the impurity heat insulation layer.

[0015] (2) The present application utilizes the characteristics of the above-mentioned hot wastewater passing through the inside of the separation tank, and inclines the second inclined plate inside the equipment. When the hot wastewater flows through multiple heat exchange pipes, the impact force of the wastewater decreases, and the impurities contained in the wastewater will slowly deposit. When the wastewater passes through the separation tank, part of the impurities will enter the gap between the second inclined plates due to the downward deposition. Since the second inclined plates are obstructed, the flow disturbance between the gaps of the second inclined plates is small, and the impurities entering the inside of the second inclined plates will deposit inside the second inclined plates. Through the application of the above-mentioned assembly, the impurities in the wastewater are effectively intercepted, and the impurities in the fixed pipe are prevented from contacting the heat exchange pipe again, which leads to the accumulation of impurities on the outer wall of the heat exchange pipe. (3) The present application utilizes the characteristics of the above-mentioned second inclined plate intercepting impurities, and sets an accumulation assembly inside the equipment. Figure 7 As shown in the figure, when the wastewater flowing out of the flow-through port two enters the side wall of the second inclined plate through P, a rightward impact force will be generated on the left side of the second inclined plate, which makes the impurities accumulated between the second inclined plates flow through the flow-through hole, finally reaches the top of the intercommunication hole, and deposits downward. The impurities will enter the inside of the storage tank along the inner wall of the inclined plate. Through the application of the above-mentioned assembly, the phenomenon of secondary scattering of impurities due to the influence of external water flow after the impurities are collected is effectively prevented.

[0016] (4) The application utilizes the above-mentioned characteristics of hot waste water flowing from top to bottom, and sets isolation components and separation boxes inside the equipment, wherein the waste water from the hot waste water inlet pipe contacts with the heat exchange pipe through the drainage mechanism to complete the single heat exchange process, then enters the inside of the separation box through the flow-through port two, and is discharged from the other end of the separation box, and contacts with the outer wall of the heat exchange pipe to be heated for the second time, then the hot waste water reaches the other side of the separation plate two through the flow-through hole, and is finally discharged from the hot waste water outlet pipe, through the application of the above-mentioned components, the contact surface of the hot waste water and the heat exchange pipe is effectively increased, and the heat exchange efficiency of the heat exchange pipe is improved.

[0025] In the second embodiment, please refer to Figure 3 - Figure 8 The heat exchange device for the geothermal system comprises the exchange assembly 11, the shell 13, the isolation assembly 12, the drainage mechanism 2, and the separation mechanism 3. The outer wall of the partition ring two 114 is fixedly connected to the inner wall of the shell 13, and the partition ring one 111 and the partition ring two 114 divide the shell 13 into three spaces.

[0026] The isolation assembly 12 comprises a partition plate one 121 fixedly connected to the outer wall of the heat exchange pipe 112. Wherein, by using the characteristics of the hot wastewater through the separation tank 311 inside, the inclined plate two 312 is tilted in the equipment, and when the hot wastewater flows through the plurality of heat exchange pipes 112, the impact force of the wastewater decreases at this time, and the impurities contained in the wastewater will be slowly deposited, and when the wastewater passes through the separation tank 311, part of the impurities will be deposited downward and enter the gap between the inclined plate two 312, and due to the obstruction of the inclined plate two 312, the turbulence between the gaps of the inclined plate two 312 is small, and the impurities entering the inside of the inclined plate two 312 will be deposited in the inside of the inclined plate two 312. Through the application of the above components, the impurities in the wastewater are effectively intercepted, and the impurities in the fixed pipe 211 are prevented from contacting the heat exchange pipe 112 again, resulting in the accumulation of impurities on the outer wall of the heat exchange pipe 112.

[0027] The rotating assembly 21 comprises a fixed pipe 211 fixedly connected to the inner wall of the shell 13, a partition ring one 212 fixedly connected to the side wall of the fixed pipe 211, a flow port one 213 formed in the side wall of the fixed pipe 211, and a flow port two 214 formed in the side wall of the fixed pipe 211. Wherein, for the problem of single hot wastewater inlet, which causes the accumulation of impurities on the top of the outer wall of the heat exchange pipe 112 affecting the heat conductivity, the isolation mechanism 1 and the drainage mechanism 2 are arranged in the equipment, and when the hot wastewater flows from the hot wastewater inlet pipe 16 inwardly, as shown in the figure, the impact force generated by the hot wastewater will act on the outer wall of the inclined blade 222, and force the rotating ring 221 to rotate along the outer wall of the partition ring one 212. Figure 3 Figure 4 The hot wastewater will flow along the K path in the figure, and be temporarily accumulated in the inside of the rotating ring 221, and in the rotating process of the rotating ring 221, the flow port three 223 will also rotate synchronously, and in the rotating process, the flow port three 223 and the flow port one 213 are in the state of coincidence, and the hot wastewater accumulated in the inside of the rotating ring 221 will flow downwardly through the flow port three 223 and the flow port one 213, and impact the outer wall of the heat exchange pipe 112, completing the basic heat exchange process.

[0028] The flow assembly 22 comprises a rotating ring 221 rotatably connected to the outer wall of the partition ring one 212, an inclined blade 222 fixedly connected to the side wall of the rotating ring 221, and a flow port three 223 formed in the side wall of the rotating ring 221. ​Wherein, since the rotating ring 221 is always in a rotating state during operation, this makes the four flow-through ports three 223 circulate through the outer wall of the flow-through port one 213, and during the process of the flow-through port three 223 passing through the flow-through port one 213, since the coinciding position of the flow-through port three 223 and the flow-through port one 213 changes constantly, this makes the position of the hot wastewater entering change constantly, through the application of the above-mentioned assembly, since the heat exchange pipes 112 are all cylindrical, when the wastewater passes through the heat exchange pipes 112, the wastewater will impact the outer wall of the heat exchange pipes 112, if the outer wall of the heat exchange pipes 112 is sticky with impurities, under the condition that the water inlet position changes constantly, the multi-angle wastewater impact will effectively prevent the sticking of impurities and reduce the generation efficiency of the impurity heat insulation layer.

[0029] The trapping assembly 31 comprises a separation tank 311 connected through the bottom of the shell 13, a plurality of inclined plates two 312 are fixedly connected at the inner wall of the separation tank 311, and flow-through holes 313 are formed in the side wall of the plurality of inclined plates two 312; Wherein, by utilizing the characteristics that the hot wastewater needs to flow from top to bottom, the isolation assembly 12 and the separation tank 311 are arranged inside the equipment, the wastewater entering from the hot wastewater inlet pipe 16 contacts the heat exchange pipes 112 through the drainage mechanism 2 to complete a single heat exchange process, then enters the inside of the separation tank 311 through the flow-through port two 214, and is discharged outward from the other end outlet of the separation tank 311, and contacts the outer wall of the heat exchange pipes 112 to be heated for the second time, then the hot wastewater reaches the other side of the partition plate two 122 through the flow-through hole 123, and is finally discharged outward from the hot wastewater outlet pipe 17, through the application of the above-mentioned assembly, the contact surface between the hot wastewater and the heat exchange pipes 112 is effectively increased, and the heat exchange efficiency of the heat exchange pipes 112 is improved.

[0030] The accumulation assembly 32 comprises a storage tank 321 fixedly connected at the bottom of the separation tank 311, an inclined surface plate 322 is fixedly connected at the side wall of the storage tank 321, and an intercommunication hole 323 is formed in the bottom of the separation tank 311; Wherein, by utilizing the characteristics that the inclined plate two 312 intercepts impurities, the accumulation assembly 32 is arranged inside the equipment, wherein, as shown in Figure 7 When the wastewater flowing out of the flow-through port two 214 passes P through the side wall of the inclined plate two 312, a rightward impact force will be generated on the left side of the inclined plate two 312, which makes the impurities accumulated between the inclined plate two 312 flow through the flow-through hole 313, and finally reach the top of the intercommunication hole 323 and deposit downward, and the impurities will enter the inside of the storage tank 321 along the inner wall of the inclined surface plate 322, through the application of the above-mentioned assembly, the phenomenon that the impurities scatter again after being collected due to the influence of external water flow is effectively prevented.

[0031] A specific application of this embodiment is as follows: Before use, the device is fixed in the required position. Then, the external hot wastewater pipe is connected to the hot wastewater inlet pipe 16, and the clean water pipe is connected to the clean water inlet pipe 14. The clean water enters the interior of the outer shell 13 through the clean water inlet pipe 14 and is discharged outward from the clean water outlet pipe 15 through the isolation mechanism 1. The hot wastewater enters the interior of the outer shell 13 through the hot wastewater inlet pipe 16 and heats the isolation mechanism 1 and the clean water inside. Finally, the hot wastewater is discharged outward through the hot wastewater outlet pipe 17. To address the issue of impurities accumulating on the top of the outer wall of the heat exchange tube 112 due to a single hot wastewater inlet, affecting thermal conductivity, an isolation mechanism 1 and a drainage mechanism 2 are installed inside the equipment. When hot wastewater flows inward from the hot wastewater inlet pipe 16, if... Figure 3 As shown, the impact force generated by the hot wastewater will act on the outer wall of the inclined blade 222, forcing the rotating ring 221 to rotate along the outer wall of the separating ring 212. Simultaneously, the hot wastewater will flow along... Figure 4 The wastewater flows through the K-path and briefly accumulates inside the rotating ring 221. During the rotation of the rotating ring 221, the flow port 3 223 also rotates synchronously, coinciding with the flow port 1 213. The hot wastewater accumulated inside the rotating ring 221 flows downwards through the flow port 3 223 and the flow port 1 213, impacting the outer wall of the heat exchange tube 112 and completing the basic heat exchange process. Because the rotating ring 221 is constantly rotating during operation, the four flow ports 3 223 circulate through the outer wall of the flow port 1 213. As the flow port 223 passes through the flow port 213, the overlapping position of the flow port 223 and the flow port 213 changes continuously, causing the entry point of the hot wastewater to change continuously. Through the application of the above components, since the heat exchange tubes 112 are all cylindrical, when the wastewater passes through the heat exchange tubes 112, the wastewater will impact the outer wall of the heat exchange tubes 112. If impurities adhere to the outer wall of the heat exchange tubes 112, the multi-angle impact of the wastewater under the condition of constantly changing water entry position will effectively prevent the adhesion of impurities and reduce the formation efficiency of the impurity insulation layer.

[0032] Taking advantage of the fact that the hot wastewater needs to flow from top to bottom, an isolation component 12 and a separation box 311 are installed inside the equipment. The wastewater entering from the hot wastewater inlet pipe 16 completes a single heat exchange process by contacting the heat exchange tube 112 through the drainage mechanism 2. Then, it enters the separation box 311 through the flow port 214 and is discharged outward from the other end of the separation box 311, where it contacts the outer wall of the heat exchange tube 112 for secondary heating. Subsequently, the hot wastewater reaches the other side of the partition plate 122 through the flow hole 123 and is finally discharged outward from the hot wastewater outlet pipe 17. Through the application of the above components, the contact surface between the hot wastewater and the heat exchange tube 112 is effectively increased, thereby improving the heat exchange efficiency of the heat exchange tube 112.

[0033] Utilizing the characteristics of the hot wastewater passing through the inside of the separation box 311, the second inclined plate 312 is arranged inside the device, when the hot wastewater flows through the plurality of heat exchange pipes 112, at this time, the impact force of the wastewater is reduced, the impurities contained in the wastewater will be slowly deposited, when the wastewater passes through the separation box 311, part of the impurities will be deposited downward and enter the gap between the second inclined plate 312, and due to the obstruction of the second inclined plate 312, this makes the turbulence between the gaps of the second inclined plate 312 small, the impurities entering the inside of the second inclined plate 312 will be deposited inside the second inclined plate 312, through the application of the above-mentioned components, the impurities in the wastewater are effectively intercepted, and the impurities in the fixed pipe 211 are prevented from contacting the heat exchange pipe 112 again, resulting in the accumulation of impurities on the outer wall of the heat exchange pipe 112; Utilizing the characteristics of the second inclined plate 312 intercepting impurities, the device is provided with an accumulation assembly 32, wherein, as shown in Figure 7 When the wastewater flowing out of the second flow port 214 passes through P and enters the side wall of the second inclined plate 312, a rightward impact force will be generated on the left side of the second inclined plate 312, which makes the impurities accumulated between the second inclined plate 312 flow through the flow-through hole 313, and finally reach the top of the intercommunication hole 323 and deposit downward, and the impurities will enter the inside of the storage box 321 along the inner wall of the inclined plate 322, through the application of the above-mentioned components, the phenomenon of the impurities being scattered again due to the influence of the external water flow after the impurities are effectively collected.
