Description

Technical Field

[0001] The present invention relates to the field of heat exchangers, and more particularly to a high-efficiency and energy-saving heat exchanger. Background Art

[0002] A heat exchanger is an energy-saving device that transfers heat between two or more fluids (liquids and gases) at different temperatures. It transfers heat from a higher-temperature fluid to a lower-temperature fluid, allowing the fluid temperature to reach the specified process temperature to meet the process requirements. It is also one of the main devices for improving energy efficiency. Based on the heat transfer principle, it can be divided into three categories: partitioning heat exchangers, heat storage heat exchangers, and hybrid heat exchangers. In chemical production, partitioning heat exchangers are the most widely used; based on their use, they can be divided into heaters, coolers, condensers (or condensers), and reboilers; and based on their structure, they can be divided into floating head heat exchangers, coil heat exchangers, spiral plate heat exchangers, and air-cooled heat exchangers.

[0003] Heat exchangers are not limited to heat exchange between liquids. They can also be used for heat exchange between non-liquids, and between liquids and non-liquids (such as gases). The core function of a heat exchanger is to transfer heat between different media. Therefore, as long as there is a temperature difference between the two media and they can exchange heat through the heat exchanger wall, a heat exchanger can be used. Liquid-gas heat exchangers are widely used in refrigeration, air conditioning, chemical industry and other fields. For example, in a refrigeration system, a condenser is a typical liquid-gas heat exchanger, which condenses the refrigerant from gas to liquid while releasing heat.

[0004] In the prior art, during the operation of the liquid-gas heat exchanger, if the temperature of the liquid coolant is low and the temperature of the gas to be cooled is relatively high, and the gas contains water vapor, then during the heat exchange between the gas and the coolant, the water vapor condenses into condensed water on the outside of the pipe wall. Although the condensed water accumulated inside the shell will be quickly discharged, the condensed water will still adhere to the fine impurities inside the gas after contacting with the gas, and will adhere to the inner wall of the shell after contacting with the inner wall of the shell, eventually forming dirt, thereby accelerating the corrosion of the inner wall of the shell. Summary of the Invention

[0005] In view of the problems existing in the prior art, the object of the present invention is to provide a high-efficiency and energy-saving heat exchanger.

[0006] To solve the above problems, the present invention adopts the following technical solution, which can realize that the absorbent cotton can absorb the condensed water accumulated on the surface of the copper tube after contacting with the copper tube, and also prevent the condensed water from absorbing fine impurities inside the gas after contacting with the gas and accumulating at the lower part of the shell.

[0011] Furthermore, a water squeezing assembly is provided inside the shell, and the water squeezing assembly includes guide grooves opened on the left and right sides of the front and rear side walls inside the shell.

[0012] Furthermore, the front and rear sides of the first support seat are fixedly connected with guide blocks, and the guide blocks are slidably connected in the guide grooves. The front and rear sides corresponding to the left and right sides of the first support seat and the second support seat are provided with sliding grooves, and the interior of the sliding grooves is slidably connected with sliders. Connecting rods are cross-hinged between the left and right adjacent first support seats and the second support seats, and the front and rear sides of the connecting rods are hinged to the sliders. The front and rear sides corresponding to the sides away from the sliders are fixedly connected with pressure springs, and the other end of the pressure springs is fixedly connected to the side of the sliding groove away from the slider.

[0013] Furthermore, the guide groove is in an "L" shape, and a controller is provided on the front side of the shell. The controller, the electric push rod and the dual-axis motor are all electrically connected to an external power supply.

[0014] Furthermore, a support assembly is provided inside the shell, and the support assembly includes hollow grooves arranged in a transverse linear array and extending through the hollow grooves.

[0015] Furthermore, a support bar is slidably connected to the interior of the hollow groove, and the support bar is in an "L" shape. A plurality of the support bars are fixedly connected to the upper sides of the corresponding first support seats on the left and right.

[0020] The present invention squeezes the absorbent cotton in the process of moving closer to the second support seat through the first support seat. Since the absorbent cotton will be squeezed after absorbing the condensed water, part of the condensed water is discharged in time, and the accumulation of impurities in the lower part of the shell is reduced, while the remaining condensed water is dried. At the same time, after part of the condensed water is squeezed out, the subsequent absorption efficiency of the absorbent cotton on the condensed water can be guaranteed.

[0021] The present invention supports the absorbent quilt during the squeezing process by providing support bars. Since the support bars always support the squeezed absorbent cotton during the squeezing process, the absorbent cotton 262 can be prevented from deviating during the squeezing process, thereby ensuring the squeezing effect of the first support seat and the second support seat on the absorbent cotton.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8 , a high-efficiency and energy-saving heat exchanger, comprising a shell 1 and a copper tube 11 penetrating the interior of the shell 1, wherein an absorption component 2 is provided inside the shell 1;

[0034] The absorbing component 2 includes a driving member 21 arranged inside the shell 1, and a moving groove 22 is opened on the left and right sides of the lower end of the interior of the shell 1. The interior of the moving groove 22 is slidably connected to a moving seat 23, and the moving seat 23 is sleeved on the outer side of the driving member 21. A first limiting groove 24 is opened inside the moving seat 23, and the interior of the first limiting groove 24 is slidably connected to a first limiting rod 241. A second limiting groove 25 is opened at the center of the lower end of the interior of the shell 1, and the interior of the second limiting groove 25 is slidably connected to a second limiting rod 251. The top of the first limiting rod 241 is fixedly connected to the first support seat 26, and the top of the second limiting rod 251 is fixedly connected to the second support seat 261. Water-absorbing cotton 262 is commonly provided on the upper sides of the first support seat 26 and the second support seat 261 on the left and right sides. An electric push rod 27 is provided on the front and rear sides of the center of the lower end of the interior of the shell 1, and the telescopic end of the electric push rod 27 is fixedly connected to the lower side of the second support seat 261.

[0035] The driving member 21 includes a dual-axis motor, a screw and a screw nut. The dual-axis motor is arranged inside the housing 1. The output ends of the dual-axis motor are fixedly connected to one end of the opposite surface of the left and right corresponding screws respectively. The screw nut is threadedly connected to the outside of the screw. The moving seat 23 is sleeved on the outside of the screw nut. The screw is inside the moving groove 22, and the screw nut moves inside the moving groove 22.

[0036] The shape of the first limiting groove 24 is adapted to the shape of the first limiting rod 241 , and the shape of the second limiting groove 25 is adapted to the shape of the second limiting rod 251 . The absorbent cotton 262 is located below the copper tube 11 , and the absorbent cotton 262 moves upward and is squeezed into contact with the outer surface of the copper tube 11 .

[0037] A water squeezing assembly 28 is provided inside the housing 1 .

[0038] By adopting the above technical solution, before the hot air flow is transported to the inside of the shell 1, the coolant is transported through the copper tube 11. In the process of the coolant passing through the copper tube 11, when the gas flows through the tube wall of the copper tube 11, heat exchange occurs between the tube wall and the fluid, that is, heat conduction, and when the liquid flows in the tube, it absorbs the heat on the inner wall of the tube and takes it away. At the same time, the gas flows outside the tube, exchanges heat with the outer wall of the tube, transfers the heat to the tube wall, and then transfers the heat from the tube wall to the liquid flowing in the tube. In the process of heat exchange between the gas and the coolant, the temperature of the gas will drop below the dew point, causing water vapor to form condensed water on the outside of the pipe. At this time, the electric push rod 27 is started to push the second support seat 261 upward, and the second support seat 261 cooperates with the water squeezing assembly 28 to drive the two first support seats 26 to move upward. In the process of the first support seat 26 moving upward, the guide blocks 282 on the front and rear sides of the first support seat 26 will be in the guide groove 28 1 moves upward, and during this process, the first limiting rod 241 under the first supporting seat 26 moves up and down in the first limiting groove 24 inside the moving seat 23, and the second limiting rod 251 on the lower side of the second supporting seat 261 moves up and down inside the second limiting groove 25. After the first supporting seat 26 and the second supporting seat 261 move upward synchronously, the first supporting seat 26 and the second supporting seat 261 will drive the absorbent cotton 262 above them to contact the surface of the copper tube 11 and absorb the condensed water on the surface of the copper tube 11. Since the absorbent cotton 262 absorbs the condensed water accumulated on the surface of the copper tube 11 after contacting the copper tube 11, it effectively prevents the condensed water from accumulating to a certain amount and falling below the inside of the shell 1. At the same time, it also prevents the condensed water from absorbing fine impurities in the gas after contacting the gas and accumulating below the inside of the shell 1, thereby reducing the possibility of fine impurities after the condensed water is discharged causing corrosion to the inner wall of the shell 1 and breeding bacteria.

[0039] like Figures 4 to 8 As shown, the water squeezing assembly 28 includes guide grooves 281 provided on the left and right sides of the front and rear side walls inside the housing 1 .

[0040] The front and rear sides of the first support seat 26 are fixedly connected with guide blocks 282, and the guide blocks 282 are slidably connected in the guide groove 281. The front and rear sides corresponding to the left and right sides of the first support seat 26 and the second support seat 261 are provided with sliding grooves 283, and the inside of the sliding groove 283 is slidably connected with a slider 284. A connecting rod 286 is cross-hinged between the left and right adjacent first support seats 26 and second support seats 261. The front and rear sides of the connecting rod 286 are hinged to the slider 284, and the front and rear sides corresponding to the slider 284 away from the side are fixedly connected with a pressure spring 285, and the other end of the pressure spring 285 is fixedly connected to the side of the sliding groove 283 away from the slider 284.

[0041] The guide groove 281 is in an L-shape. A controller 287 is provided on the front side of the housing 1 . The controller 287 , the electric push rod 27 and the dual-axis motor are all electrically connected to an external power supply.

[0042] By adopting the above technical solution, when the guide block 282 returns to the bottom of the vertical part of the guide groove 281, the controller 287 will control the dual-axis motor of the driving part 21 to operate according to the preset system, and after the dual-axis motor is running, it will drive the two screws to rotate at the same time. After the screw rotates, the screw nut on the outside will move left and right on the outside of the screw and according to the thread direction of the screw, and drive the moving seat 23 on the outside of the screw nut to move inside the moving groove 22. When the two moving seats 23 begin to move closer, the guide block 282 will slide inside the horizontal part of the guide groove 281, and at the same time drive the two first support seats 26 to move closer to each other. Because the second support seat 261 is always in place, in the process of the first support seat 26 approaching the second support seat 261, the cross-hinged connecting rod 286 begins to rotate, and at the same time, the sliders 284 at both ends of the two connecting rods 286 will slide inside the slide groove 283. The first support seat 26 and the second support seat 261 move together, and the pressure spring 285 inside the slide groove 283 is squeezed. As the first support seat 26 and the second support seat 261 move closer, the absorbent cotton 262 above the first support seat 26 and the second support seat 261 will also be squeezed. At this time, part of the condensed water absorbed by the absorbent cotton 262 will be discharged from the bottom of the absorbent cotton 262. Then the dual-axis motor rotates in the opposite direction, so that the guide block 282 returns to its original position, and the absorbent cotton 262 is unfolded again. When the air flow enters the interior of the shell 1, the remaining condensed water inside the absorbent cotton 262 will be dried, and impurities will remain inside the absorbent cotton 262. Since the absorbent cotton 262 will be squeezed after absorbing the condensed water, part of the condensed water is discharged in time, and the accumulation of impurities at the bottom of the shell 1 is reduced, and the remaining condensed water is dried. At the same time, after part of the condensed water is squeezed out, the subsequent absorption efficiency of the absorbent cotton 262 for condensed water can be guaranteed.

[0043] like Figures 4 to 7 As shown, a support assembly 29 is provided inside the housing 1 , and the support assembly 29 includes hollow slots 291 arranged in a transverse linear array and extending therethrough.

[0044] A support bar 292 is slidably connected to the interior of the hollow groove 291 . The support bar 292 is L-shaped. A plurality of support bars 292 are fixedly connected to the upper sides of the corresponding first support seats 26 on the left and right sides.

[0045] By adopting the above technical solution, when the first support seat 26 and the second support seat 261 approach each other, the support bar 292 above the first support seat 26 is always inserted into the hollow groove 291 inside the absorbent cotton 262, and the other end of the support bar 292 extends to the top of the second support seat 261, but does not directly contact the second support seat 261. As the first support seat 26 moves, the support bar 292 will also move synchronously and support the absorbent cotton 262. Since the support bar 292 always supports the squeezed absorbent cotton 262 during the squeezing of the absorbent cotton 262, the deviation of the absorbent cotton 262 during the squeezing process can be avoided, thereby ensuring the water squeezing effect of the first support seat 26 and the second support seat 261 on the absorbent cotton 262.

[0046] like Figure 2 and Figure 3 As shown, a scraping component 3 is provided inside the housing 1 , and the scraping component 3 includes scrapers 31 fixedly connected to the front and rear sides of the movable base 23 .

[0047] Slopes 32 are provided on both the front and rear sides of the lower end of the interior of the shell 1. The inclined surface of the slope 32 faces the movable groove 22. The lower side of the scraper 31 is in sliding contact with the inclined surface of the slope 32. A centralizing groove 33 is provided on the lower inner side of the movable groove 22. The centralizing groove 33 is connected to the movable groove 22. The left and right corresponding centralizing grooves 33 are located on the left and right sides of the dual-axis motor.

[0048] By adopting the above technical solution, as the driving member 21 drives the movable seat 23 to move, the scrapers 31 on the front and rear sides of the movable seat 23 are always in contact with the slope 32, and the movable seat 23 is in contact with the inner wall of the movable groove 22. When impurities accumulate on the slope 32 and the side walls of the movable seat 23, the scrapers 31 and the movable seat 23 will scrape off the impurities accumulated on the slope 32 and the side walls of the movable seat 23 until they move to the position of the central groove 33, so that the impurities are finally discharged through the central groove 33. Since the scrapers 31 and the movable seat 23 will scrape off the impurities accumulated on the slope 32 and the side walls of the movable seat 23 during the movement, it is again avoided that the impurities accumulate for a long time at the lower part of the shell 1 and cause corrosion to the inner wall of the shell 1 or breed bacteria.

[0049] Working principle: When gas flows through the wall of the copper tube 11, heat exchange occurs between the tube wall and the fluid to form condensed water. At this time, the electric push rod 27 is started to push the second support seat 261 upward, and the second support seat 261 cooperates with the water squeezing assembly 28 to drive the two first support seats 26 to move upward, and the guide blocks 282 on the front and rear sides of the first support seat 26 will move upward inside the guide groove 281, so that the first support seat 26 and the second support seat 261 will drive the absorbent cotton 262 above them to contact the surface of the copper tube 11 and absorb the condensed water on the surface of the copper tube 11. When the guide block 282 returns to the bottom of the vertical part of the guide groove 281, the controller 287 will control the dual-axis motor in the driving member 21 to operate according to the preset system, and drive the moving seat 23 to move inside the moving groove 22. When the two moving seats 23 begin to move closer, the two first support seats 26 move closer to each other. Because the second support seat 261 is always in place, the first support seat 26 and the second support seat 261 are connected by a cross-hinged connecting rod. 286 starts to rotate, and then squeezes the absorbent cotton 262. Then the dual-axis motor rotates in the opposite direction, so that the guide block 282 returns to its original position, and the absorbent cotton 262 is re-expanded. When the air flow enters the interior of the shell 1, the remaining condensed water inside the absorbent cotton 262 will be dried, and impurities will remain inside the absorbent cotton 262. In the process of the first support seat 26 and the second support seat 261 approaching each other, the support bar 292 above the first support seat 26 is always inserted into the hollow groove 292 inside the absorbent cotton 262. 91, the support bar 292 will also move synchronously at this time and support the absorbent cotton 262, because the scrapers 31 on the front and rear sides of the moving seat 23 are always in contact with the slope 32, and the moving seat 23 is in contact with the inner wall of the moving groove 22. When impurities accumulate on the slope 32 and the side walls of the moving seat 23, the scrapers 31 and the moving seat 23 will scrape off the impurities accumulated on the slope 32 and the side walls of the moving seat 23 until they move to the position of the central groove 33, so that the impurities are finally discharged through the central groove 33.

[0050] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
