Description

Technical Field

[0001] This application relates to the field of graphite heat exchanger technology, and in particular to an energy-saving graphite heat exchanger with an adjustable area. Background Technology

[0002] Graphite heat exchangers are heat exchangers whose heat transfer components are made of graphite. Graphite heat exchangers have advantages such as good corrosion resistance, minimal scaling on the heat transfer surface, and excellent heat transfer performance. They are mainly used for heat exchange with corrosive media such as hydrochloric acid, sulfuric acid, acetic acid, and phosphoric acid. Currently, graphite heat exchangers are widely used in industries such as chlor-alkali chemical, petrochemical, fluoride salt, titanium dioxide, zirconium, chloroacetic acid, chlorinated paraffin, and monocrystalline silicon fluorochemicals.

[0003] In related technologies, the graphite blocks installed in graphite heat exchangers are usually of a single integrated structure, which cannot adjust the area of ​​the graphite heat exchange structure as needed. This results in poor versatility and an inability to maintain good heat exchange efficiency in different heat exchange tasks. It can also lead to a fixed heat exchange area, resulting in energy waste or insufficient heat exchange.

[0004] Therefore, we propose an energy-saving graphite heat exchanger with easily adjustable area to solve the above problems. Utility Model Content

This improves the adaptability and versatility of the graphite heat exchanger, enables effective control of fluid temperature, and achieves energy-saving and high-efficiency heat exchange.

[0020] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] See Figure 1 , Figure 2 and Figure 3 This application provides an energy-saving graphite heat exchanger with adjustable area, including a heat exchanger shell 1. A bracket 2 is fixedly installed on the outer wall of the heat exchanger shell 1. A graphite heat exchange block 3 is fixedly installed inside the heat exchanger shell 1. A receiving groove 4 is fixedly installed on both sides of the graphite heat exchange block 3. Multiple evenly distributed liquid passage holes 5 are opened in the graphite heat exchange block 3. The two ends of the liquid passage holes 5 are respectively connected to the corresponding receiving grooves 4. Graphite heat exchange blocks 6 are slidably installed in both receiving grooves 4. The two graphite heat exchange blocks 6 extend to the outside of the corresponding receiving grooves 4 on their respective opposite sides. Multiple evenly distributed liquid passage holes 7 are opened on both graphite heat exchange blocks 6. Each side of the heat exchanger shell 1 is fixedly fitted with a sealing ring 8. The outer ring wall of the sealing ring 8 slides and seals against the inner wall of the heat exchanger shell 1. The top of the heat exchanger shell 1 is fixedly connected to a coolant inlet pipe 13 located between the two sealing rings 8. The bottom of the heat exchanger shell 1 is fixedly connected to a coolant outlet pipe 14 located between the two sealing rings 8. The left side of the heat exchanger shell 1 is fixedly connected to a fluid inlet pipe 15, and the right side of the heat exchanger shell 1 is fixedly connected to a fluid outlet pipe 16. By using the two sealing rings 8, it can be ensured that the fluid can only flow through multiple liquid passage holes 7 and multiple liquid passage holes 5, and that the coolant can only flow between the two sealing rings 8, thus ensuring the normal and stable operation of the graphite heat exchanger.

[0022] A drive mechanism is installed inside the heat exchanger shell 1, located between two sealing rings 8. This drive mechanism controls the horizontal linear movement of the two sealing rings 8 and controls the sliding of the two graphite heat exchange blocks 6 within their corresponding receiving slots. This allows for convenient adjustment of the overall heat exchange area of ​​the two graphite heat exchange blocks 6 and the graphite heat exchange block 3. When actual operating conditions change the heat exchange requirements, this mechanism can be flexibly adjusted, improving the adaptability and versatility of the equipment. It maintains good heat exchange efficiency in different heat exchange tasks, avoiding energy waste or insufficient heat exchange caused by a fixed heat exchange area. The drive mechanism includes a protective shell 10, two electric telescopic rods 11, and two push rods 12. The protective shell 10 is fixedly installed... Installed on the bottom inner wall of the heat exchanger shell 1, two electric telescopic rods 11 are fixedly installed inside the protective shell 10 and are symmetrically distributed. Two push rods 12 are respectively fixedly installed on the output shaft ends of the corresponding electric telescopic rods 11. The ends of the two push rods 12 that are far apart from each other extend outside the protective shell 10, and the ends of the two push rods 12 that are far apart from each other are respectively fixedly connected to the sides of the two sealing rings 8 that are close to each other. Utilizing the telescopic feature of the electric telescopic rods 11, the push rods 12 can be controlled to move horizontally in a straight line, which in turn can push the corresponding sealing rings 8 to move horizontally in a straight line, so that the graphite heat exchange block 2 6 moves with the sealing rings 8, thereby changing the overall heat exchange area of ​​the two graphite heat exchange blocks 2 6 and the graphite heat exchange block 1 3.

[0023] In this embodiment, multiple positioning blocks 9 are fixedly installed on the outer wall of the graphite heat exchange block 3 in a ring with equal spacing. The multiple positioning blocks 9 are fixedly connected to the inner wall of the heat exchanger shell 1, which plays the role of supporting and positioning the graphite heat exchange block 3.

[0024] In this embodiment, clearance holes are provided on the left and right sides of the protective shell 10. The ends of the two push rods 12 that are far apart from each other pass through the corresponding clearance holes. A sealing ring is fixedly installed in the clearance hole. The push rod 12 slides and seals with the clearance hole through the sealing ring, which can ensure that the push rod 12 moves smoothly and effectively seal the gap between the push rod 12 and the clearance hole, ensuring that the coolant will not enter the protective shell 10.

[0025] In this embodiment, limiting grooves are provided on the top and bottom inner walls of the receiving tank 4. Limiting rods are fixedly installed on the top and bottom of the graphite heat exchange block 2 6. The two limiting rods are slidably installed in the corresponding limiting grooves, which limit the movement stroke of the graphite heat exchange block 2 6 and guide the movement direction of the graphite heat exchange block 2 6. A sealing ring 2 is fixedly installed on the inner wall of the receiving tank 4. The graphite heat exchange block 2 6 slides and seals with the receiving tank 4 through the sealing ring 2, which can effectively seal the gap between the graphite heat exchange block 2 6 and the receiving tank 4, preventing fluid from flowing out of the receiving tank 4 and preventing coolant from entering the receiving tank 4, so that the coolant and fluid will not directly contact and mix.

[0026] In this embodiment, it should be noted that both sealing ring one and sealing ring two are made of wear-resistant and corrosion-resistant sealing rings, the protective shell 10 is made of a corrosion-resistant material, and both electric telescopic rods 11 can be purchased on the market or customized in the factory. The wiring and control methods of the two electric telescopic rods 11 are mature technologies in the field and will be fully disclosed in this document, so they will not be described in detail here.

[0027] With the above structure, the working principle of the energy-saving graphite heat exchanger with easily adjustable area provided in this application is as follows:

[0028] During the heat exchange process, the fluid enters from the left fluid inlet pipe 15 of the heat exchanger shell 1, allowing the fluid to flow sequentially through the liquid passage hole 7 of the left graphite heat exchange block 2 6, the liquid passage hole 5 of the graphite heat exchange block 1 3, and the liquid passage hole 7 of the right graphite heat exchange block 2 6. At the same time, the coolant enters from the coolant inlet pipe 13 at the top of the heat exchanger shell 1 into the space between the two sealing rings 8. During this process, the heat in the fluid is transferred to the coolant through the graphite heat exchange block 1 3 and the two graphite heat exchange blocks 2 6, achieving heat exchange. Finally, the cooled fluid is discharged from the right fluid outlet pipe 16 of the heat exchanger shell 1, and the coolant that has absorbed heat is discharged from the coolant outlet pipe 14 at the bottom.

[0029] When the heat exchange area needs to be adjusted, the two electric telescopic rods 11 are extended. The output shafts of the two electric telescopic rods 11 drive the corresponding push rods 12 to move linearly. The two push rods 12 drive the corresponding sealing rings 8 to move linearly. At this time, the two sealing rings 8 move away from each other, causing the two graphite heat exchange blocks 2 6 to move with the corresponding sealing rings 8. The two graphite heat exchange blocks 2 6 gradually slide out of the corresponding receiving groove 4. At this time, the total heat exchange area of ​​the two graphite heat exchange blocks 2 6 and the graphite heat exchange block 1 3 gradually increases. Similarly, by retracting and resetting the two electric telescopic rods 11, the two electric telescopic rods 11... The output shaft drives the corresponding push rod 12 to move linearly. The two push rods 12 drive the corresponding sealing rings 8 to move linearly. At this time, the two sealing rings 8 move closer to each other, causing the two graphite heat exchange blocks 6 to move with the corresponding sealing rings 8. The two graphite heat exchange blocks 6 gradually slide into the corresponding receiving groove 4. At this time, the total heat exchange area of ​​the two graphite heat exchange blocks 6 and the graphite heat exchange block 3 gradually decreases. Thus, the heat exchange area can be changed by adjusting the position of the two graphite heat exchange blocks 6 to adapt to different heat exchange requirements and achieve effective control of fluid temperature, thereby achieving energy-saving and efficient heat exchange.
