Description

Technical Field

[0001] The present invention relates to the technical field of heat exchangers, and in particular to a high-efficiency heat exchanger and a waste heat recovery system. Background Art

[0002] A heat exchanger is a device used to transfer heat between different media. It is commonly used in industrial production, building HVAC systems, automotive engine cooling systems and other fields. Heat transfer is the basis of the work of the heat exchanger. It mainly includes convection heat transfer, conduction heat transfer and radiation heat transfer. Understanding these heat transfer mechanisms is crucial to the design and optimization of heat exchangers. According to different working principles and application requirements, heat exchangers can be divided into many types, including shell and tube heat exchangers, plate heat exchangers, spiral plate heat exchangers, air heat exchangers, etc. Each type has its specific advantages and disadvantages and applicable scenarios. The material selection of the heat exchanger is crucial to its performance and durability. Common materials include stainless steel, copper, aluminum, titanium, etc. Some special applications may require corrosion-resistant, high-temperature-resistant or pressure-resistant materials. Understanding the flow characteristics of the fluid inside the heat exchanger is crucial to the design and performance optimization.

[0003] A Chinese patent discloses (CN113357942B) a high-efficiency plate heat exchanger with a spiral arrangement. The plate heat exchanger can reduce the impact of the spiral pipe on the hot runner, reduce the loss of the hot runner, improve the safety of the plate heat exchanger, effectively extend the service life of the heat flow pipe, reduce the possibility of siltation, increase the service life of the heat exchanger, and transform the heat transfer from single-line heat transfer to multi-angle and multi-directional heat transfer, so that the heat exchange area in the same volume is increased, and the heat transfer driving force is improved. However, the waste heat cannot be recovered and the circulating fluid cannot be purified.

[0004] In the existing plate heat exchanger, the two fluids to be heat transferred flow through the two sides of the plate heat exchanger respectively. One fluid usually flows through the gap between the plates (called a channel), which is called the heat source fluid (such as hot water, steam or cooling water), and the other fluid flows through the adjacent channel, which is called the working fluid (such as the heated or cooled fluid). After the heat transfer is completed, the fluids flow out from the outlet of the plate heat exchanger respectively for downstream applications or recycling. When the heat exchanger is turned off, the heat in the tube is still there, which will cause heat waste. If the heat at that time is stored and released for continued use next time, the heat waste will be greatly reduced. In order to solve the above problems, a high-efficiency heat exchanger and a waste heat recovery system are proposed. Summary of the invention

[0005] The purpose of the present invention is to improve the existing plate heat exchanger so that the heat in the tube can be stored when the heat exchanger is turned off. When the heat exchanger is used next time, the heat can be released to continue using the previously stored heat, which will ultimately greatly reduce the waste of heat and purify the fluid while storing heat.

[0006] In order to achieve the above object, the present invention adopts the following technical solution: a high-efficiency heat exchanger waste heat recovery system, comprising the following steps:

[0009] S: Heat transfer: The working fluid and the cooling medium flow through the heat transfer surfaces inside the heat exchanger, where heat is transferred from the working fluid to the cooling medium. This process is usually achieved through direct contact between the surfaces of materials with good thermal conductivity.

This heat exchange enables the effective use of thermal energy in industrial processes, such as converting thermal energy into steam, heating water or cooling medium, etc.

[0042] A high-efficiency heat exchanger, comprising a recovery and insulation storage column 1, a filtering device 2, a first fixing block 3 and a heat exchanger body 4, wherein a first fluid pipeline 101 is fixedly installed on the outside of the recovery and insulation storage column 1, a second fluid pipeline 102 is fixedly installed on one end of the recovery and insulation storage column 1 away from the first fluid pipeline 101, a three-forked bifurcated pipe 205 is fixedly installed on the outside of the recovery and insulation storage column 1, and a circulation purification component is movably connected to the outside of the three-forked bifurcated pipe 205, and the circulation purification component includes a diverter 202, a sealing switch 201 and a filter cotton core 206;

[0043] The No. 1 fixed block 3 is fixedly installed on the outside of the recovery and insulation storage column 1. The No. 1 fixed block 3 is fixedly installed on the outside of the No. 1 fixed block 3. The No. 1 motor 304 is fixedly connected to the outside of the No. 1 motor 304. The waste heat recovery component includes the No. 1 motor 304, a transmission track 305, a No. 1 threaded rod 303 and an annular inner gear 307.

[0044] The heat exchanger body 4 is fixedly installed on the outside of the recovery and insulation storage column 1, and a No. 1 metal heat conductive plate 401 is fixedly installed on the inner wall of the heat exchanger body 4, and a No. 2 metal heat conductive plate 402 is fixedly installed on the outside of the No. 1 metal heat conductive plate 401, and a No. 1 fluid connecting pipe 403 is fixedly installed on the inner wall of the heat exchanger body 4, and a No. 2 fluid connecting pipe 404 is fixedly installed on the outside of the No. 1 fluid connecting pipe 403.

[0045] By adopting the above technical solution, it is possible to transfer heat between fluids through the No. 1 metal heat conducting plate 401 and the No. 1 fluid connecting pipe 403. The No. 1 metal heat conducting plate 401 and the No. 2 metal heat conducting plate 402 use metal plates as heat exchange elements, and gaskets are sandwiched between the plates, so that the heat transfer area is increased, the heat exchange efficiency is high, and effective heat transfer can be achieved.

[0046] A No. 2 telescopic pipe 302 is fixedly installed inside the recovery insulation storage column 1, and a No. 1 threaded rod 303 is fixedly installed on the end of the recovery insulation storage column 1 away from the No. 2 telescopic pipe 302.

[0047] By adopting the above technical solution, the hydraulic baffle 309 can be moved by rotating the No. 1 threaded rod 303, and the fluid with heat in the heat exchanger can be introduced into the recovery and heat preservation storage column 1 for storage.

[0048] The No. 1 motor 304 is fixedly installed on the outside of the No. 1 fixed block 3, and the No. 1 motor 304 is externally rotatably connected to the No. 1 rotating disk 306, and the transmission crawler 305 is connected to the No. 1 rotating disk 306 crawler, and the annular inner gear 307 rotates on the outside of the recycling heat preservation storage column 1, and the annular inner gear 307 is connected to the transmission crawler 305 crawler, and the No. 1 threaded rod 303 rotates on the outside of the recycling heat preservation storage column 1, and the No. 1 threaded rod 303 is externally fixedly installed with a No. 1 gear 308, and the No. 1 gear 308 is meshed with the annular inner gear 307. By adopting the above technical solution, the No. 1 rotating disk 306 can be rotated to rotate the transmission crawler 305 and transmit it to the annular inner gear 307, and finally the No. 1 threaded rod 303 can be rotated through gear transmission.

[0049] A storage inlet pipe 204 is fixedly installed on the outside of the recovery insulation storage column 1, the No. 2 fluid pipeline 102 is fixedly installed on the outside of the heat exchanger body 4, the No. 2 fluid pipeline 102 is connected to the storage inlet pipe 204, an electromagnetic rotary switch 203 is fixedly installed on the outside of the three-pronged bifurcated pipe 205, the diverter 202 is fixedly connected to the filter device 2, the sealing switch 201 rotates on the outside of the diverter 202, the sealing switch 201 is threadedly connected to the three-pronged bifurcated pipe 205, a filter cotton core 206 is fixedly installed inside the filter device 2, and the number of filter devices 2 and the No. 1 fluid pipeline 101 are both two groups and are symmetrically distributed.

[0050] By adopting the above technical solution, when the fluid circulates in the recovery insulation storage column 1 and the heat exchanger body 4, it will pass through the filter device 2, and be filtered and removed by the filter cotton core 206 in the filter device 2 to remove bubbles. When bubbles are formed inside the plate heat exchanger, they will affect the flow and heat transfer of the fluid and reduce the efficiency of the heat exchanger. By filtering and removing bubbles from the plate heat exchanger, the impact of bubbles on the heat exchanger can be effectively reduced and the heat exchange efficiency can be improved.

[0051] Working principle: When the present invention is in use, when a high-efficiency heat exchanger is used, a fluid with high heat content enters the heat exchanger body 4 through the No. 1 fluid pipeline 101, and a fluid that needs heat exchange enters the heat exchanger body 4 through the No. 2 fluid pipeline 102, and is separated by the No. 1 metal heat conducting plate 401 and the No. 1 fluid connecting pipe 403. The heat between the fluids is transferred by the high thermal conductivity of the No. 1 metal heat conducting plate 401 and the No. 1 fluid connecting pipe 403, and the heat exchange temperature is controlled by the flow rate of the fluid;

[0052] When the heat exchanger is turned off but there is still residual heat in the heat exchanger, the No. 1 motor 304 is started to drive the No. 1 rotating disk 306 to rotate. Since the No. 1 rotating disk 306 is movably connected to the transmission track 305, the No. 1 rotating disk 306 rotates to drive the transmission track 305 to rotate. Since the transmission track 305 is movably connected to the inner ring gear 307, the transmission track 305 rotates to drive the inner ring gear 307 to rotate. Since the inner ring gear 307 is meshed with the No. 1 gear 308, the inner ring gear 307 rotates to drive the inner ring gear 307 to rotate. The first gear 308 rotates. Since the first gear 308 is fixedly connected to the first threaded rod 303, the first gear 308 rotates and drives the first threaded rod 303 to rotate. Finally, since the first threaded rod 303 is threadedly connected to the hydraulic baffle 309, the first threaded rod 303 rotates and drives the hydraulic baffle 309 to move toward the second telescopic pipe 302, and the second telescopic pipe 302 and the first telescopic pipe 301 are contracted, so that the fluid with residual heat in the heat exchanger body 4 is sucked into the recovery and heat preservation storage column 1 for storage;

[0053] When the fluid circulates through the filter device 2 in the recovery and insulation storage column 1 and the heat exchanger body 4, it is filtered and the bubbles therein are removed by the filter cotton core 206, so that the heat exchange efficiency can be improved.

[0054] Equipment damage can be prevented by filtering the circulation components. The accumulation of bubbles inside the plate heat exchanger may cause corrosion and damage to equipment components, affecting the normal operation of the equipment. Regularly filtering and removing bubbles from the plate heat exchanger can reduce this risk and extend the service life of the equipment. The presence of bubbles may cause unstable fluid flow, resulting in system pressure fluctuations and uneven temperature, affecting the stability and reliability of the system. By filtering and removing bubbles from the plate heat exchanger, the stability of the fluid flow can be maintained to ensure the normal operation of the system.

[0055] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
