Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a high-efficiency heat recovery heat exchanger. Background Technology

[0002] A heat recovery heat exchanger is a device used to recover waste heat and transfer heat. Its principle is to use waste heat for heat exchange, thereby reducing energy consumption and improving energy efficiency. Therefore, heat recovery heat exchangers play a very important role in industrial production and energy utilization.

[0003] A heat exchanger for recovering heat energy from oil fumes in a stenter (announcement number CN217005445U) is based on a base plate. A heat exchange box, a collection box, and a water pump are fixed to the top side of the base plate. A filter box and a treatment box are fixedly connected to both sides of the heat exchange box. Filter screens and activated carbon plates are movably installed inside the filter box and treatment box, respectively. In use, the heat exchanger delivers exhaust gas through an inlet pipe to the inside of the filter box, where solid impurities are filtered out. The gas then enters the heat exchange tubes and undergoes heat exchange with cooling water inside the heat exchange box. Simultaneously, high-temperature oil mist in the gas is transported to the inside of the collection box through a connecting pipe and a return pipe for collection and utilization. This heat exchange raises the water temperature, allowing for the rapid generation of high-temperature steam at the hot water output end, thus achieving heat recovery and utilization.

[0004] The heat exchanger described above for recovering heat energy from oil fumes in a stenter still has problems. During use, the heat exchanger transfers heat through bent heat exchange tubes. Due to the small surface area of ​​the heat exchange tubes, the heat transfer efficiency is low, resulting in a reduction in the heat exchanger's efficiency. Utility Model Content

[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Example 1, please refer to Figures 1-3 This is the first embodiment of the present utility model.

[0030] This embodiment provides a high-efficiency heat recovery heat exchanger, including:

[0031] Box 1, with a heat exchange mechanism 101 inside the box 1, a cleaning mechanism 102 on the top side of the box 1, and a filter mechanism 103 at one end of the inner side of the box 1.

[0032] The heat exchange mechanism 101 includes a hollow plate 2 installed at the bottom of the inner side of the housing 1. Heat exchange fins 3 are evenly fixed on the top side of the hollow plate 2. An input valve 4 is fixed through the housing 1 at one end of the hollow plate 2. A heat pump 5 is installed at one end of the housing 1. The input end of the heat pump 5 passes through the housing 1 and is connected to the inner side of the hollow plate 2 through an input pipe 6. A three-way pipe 8 is fixed through an output pipe 7 at the output end of the heat pump 5. An air inlet 9 is installed at one end of the housing 1, and an exhaust port 10 is installed at the other end of the housing 1. A water tank 12 is installed on one side of the housing 1.

[0033] Specifically, the bottom side of the water tank 12 is fixedly connected to the input end of the heat pump 5 via a water supply pipe 13, and the water tank 12 is connected to the bottom inside of the box body 1 via a drain pipe 14. An activated carbon filter 11 is fixed to one end of the exhaust port 10.

[0034] Furthermore, the condensate in the housing 1 can be transported to the inside of the water tank 12 and then output for reuse, thereby realizing the recycling of water source and reducing the operating cost of the heat exchanger.

[0035] In use, high-temperature exhaust gas is introduced through the air inlet 9, allowing it to fully contact the heat exchange fins 3 and transfer heat to the inside of the hollow plate 2. Cooling water is then introduced through the inlet valve 4, absorbing heat and rising in temperature. The heated water is then transported to the heat pump 5 to heat the water and output steam, which is then output through the three-way pipe 8. This process achieves heat recovery from the high-temperature exhaust gas with higher recovery efficiency. The condensate collected inside the water tank 12 is transported to the heat pump 5 for reuse, thereby reducing the operating cost of the heat exchanger and broadening its applicability.

[0036] In summary, through the structure of the heat exchange mechanism 101, with the cooperation of the heat exchange fins 3, the contact area between the heat exchanger and the exhaust gas can be increased, thereby fully absorbing the heat of the exhaust gas and improving the heat exchange efficiency of the heat exchanger. At the same time, the condensate inside the housing 1 can be recycled and reused, reducing the waste of water resources.

[0037] Example 2, please refer to Figures 4-5 This is the second embodiment of the present utility model.

[0038] Specifically, the cleaning mechanism 102 includes a fixing plate 15 evenly fixed to the top of the inner side of the housing 1. The fixing plate 15 is fixedly connected to the top of the heat exchange fins 3. A water spray pipe 16 is evenly rotatably inserted into the inner side of the fixing plate 15. Spray nozzles 17 are evenly fixed on the circumferential surface of the bottom end of the water spray pipe 16. A hollow tube 18 is fixed to one end of the inner side of the housing 1. One end of the water spray pipe 16 is rotatably connected to the hollow tube 18, and the water spray pipe 16 communicates with the inner side of the hollow tube 18. The hollow tube 18 is connected to a three-way valve through an air supply pipe 81. One end of the pipe 8 is connected to a gear 19 fixed to one end of the water spray pipe 16. One end of the inner side of the box body 1 is fixed to a slide rail 20. A rack 21 is slidably installed on the inner side of the slide rail 20. One end of the rack 21 passes through the box body 1 and is fixed to a limit ring 22. One end of the side of the box body 1 is fixed to a support plate 23. A drive motor 24 is fixed to the top side of the support plate 23. A turntable 25 is fixed to the output end of the drive motor 24. A limit rod 26 is fixed to the top edge of the turntable 25. The limit rod 26 is slidably installed inside the limit ring 22.

[0039] Furthermore, the rotatable water spray pipe 16 allows for thorough rinsing of the heat exchange fins 3 surface, avoiding dead corners and improving the cleaning quality of the device.

[0040] Specifically, the filter mechanism 103 includes a filter screen 27 that is slidably installed on one end of the inner side of the housing 1. Pressure plates 28 are fixed at both ends of the top side of the filter screen 27. Fixing seats 29 are symmetrically fixed at the top of both sides of the housing 1. Insert rods 30 are slidably inserted into the inner side of the fixing seats 29. Limit caps 31 are fixed at the top of the insert rods 30. Springs 32 are fixedly connected between the limit caps 31 and the fixing seats 29. Limit seats 33 are fixed on the top side of the housing 1. Fixing rods 34 are inserted into the inner side of the limit seats 33.

[0041] Furthermore, by using the insertion rod 30 in conjunction with the spring 32, the filter screen 27 can be lifted up when disassembly is required, making it convenient for operators to disassemble and install the filter screen 27 for cleaning and maintenance.

[0042] In use, pull out the fixing rod 34. At this time, the spring 32 pushes the limit cap 31 to rise, lifting the filter screen 27. The filter screen 27 can then be pulled out, cleaned, and reinstalled inside the housing 1. The fixing rod 34 is then reinserted into the limit seat 33 to fix its position. After that, the heat pump 5 can be controlled to deliver hot steam or hot water to the inside of the hollow tube 18 through the three-way pipe 8 and the gas supply pipe 81. The hot steam or hot water is then sprayed out from the nozzle 17 to tilt the surface of the heat exchange fins 3. During the cleaning process, the drive motor 24 is controlled to drive the turntable 25 to rotate. With the cooperation of the limit rod 26 and the limit ring 22, the rack 21 is driven to slide back and forth inside the slide rail 20, thereby driving the water spray pipe 16 to rotate, preventing dead corners during the cleaning process and improving the cleaning quality.

[0043] In summary, the structure of the cleaning mechanism 102 and the filtering mechanism 103 allows for the cleaning and maintenance of the internal parts of the device after use, making it more flexible and convenient for the next use.
