Description

Technical Field

[0001] This invention relates to the field of impurity removal technology, specifically to a heat exchanger with impurity treatment function. Background Technology

[0002] Heat exchangers, as key equipment for energy transfer and recovery in industrial production, are widely used in various industries such as chemical, energy, metallurgy, and refrigeration. During long-term operation, solid impurities such as silt and suspended matter carried by the heat exchange medium gradually accumulate in the heat exchange channels and surfaces. Simultaneously, the medium also generates stubborn impurities such as scale, grease, and biological slime during heat exchange. The presence of these impurities significantly reduces the heat transfer efficiency of the heat exchanger, increases operating energy consumption, and can even cause problems such as channel blockage and equipment corrosion, seriously affecting the operational stability and service life of the heat exchanger. Therefore, it is essential to regularly clean the heat exchanger to achieve energy-efficient heat exchange operation.

[0003] Currently, the industry generally uses offline cleaning methods to remove impurities from heat exchangers. The standard procedure is as follows: first, high-pressure water rinsing is used to remove accumulated solid impurities, followed by chemical cleaning methods such as acid washing and alkaline washing to remove stubborn impurities such as scale and grease. The reaction efficiency of acid washing and alkaline washing is closely related to temperature. To accelerate the chemical reaction rate between the acid / alkali and the impurities, improve cleaning efficiency, and shorten cleaning time, the acid washing temperature is typically controlled at 40–60℃, and the alkaline washing temperature at 60–80℃.

[0004] However, the aforementioned conventional cleaning methods have many inherent drawbacks, severely restricting the economy and continuity of industrial production. On the one hand, to meet the temperature requirements of acid and alkaline washing, enterprises need to equip themselves with corresponding heating devices to heat the cleaning solution. The purchase, installation, and energy consumption of these heating devices undoubtedly increase the additional costs of equipment maintenance and increase the pressure on production operations. On the other hand, both the high-pressure water rinsing stage and the subsequent acid and alkaline washing stages require the normal operation of the heat exchanger to be suspended and disassembled or isolated offline from the production system. This shutdown cleaning mode directly disrupts the normal production rhythm, leading to production interruptions. This not only reduces overall production efficiency but may also cause a series of chain problems such as order delays and capacity losses due to production stagnation.

[0005] In summary, existing methods for cleaning impurities from heat exchangers suffer from high costs and disruptions to production continuity, making them unsuitable for the demands of modern industry for efficient, economical, and continuous production. Summary of the Invention

[0012] Preferably, the stirring mechanism is installed at one end of the horizontal plate, and a linear bearing is installed at the other end of the horizontal plate. The linear bearing is slidably sleeved on the vertical shaft. The bottom of the telescopic cylinder located on the side of the vertical shaft is connected to the base frame, and the telescopic end of the telescopic cylinder is connected to the side plate rotatably mounted on the linear bearing.

[0013] Preferably, two clamping arc plates are bolted together on the vertical shaft, and a brake rod is fixedly installed on the side of the two clamping arc plates that is far apart from each other; a brake hole is provided on the horizontal plate; after the stirring mechanism extends into a certain stirring drum, a certain brake rod extends into the brake hole.

[0014] Preferably, a drive motor is installed on the horizontal plate, and a drive gear is fixedly installed on the power output shaft of the drive motor; a fixed gear is sleeved on the top of the vertical shaft, and a bolt is installed through the connecting pipe installed on the fixed gear, and the bolt is installed through a connecting hole of the vertical shaft; after the stirring mechanism rises, the drive gear and the fixed gear mesh, and the drive motor drives the stirring mechanism to rotate.

[0015] Preferably, multiple wheels are installed under the base frame, two sets of brackets are fixedly installed above the base frame, and a support pipe is fixedly installed between the two sets of brackets.

[0016] Preferably, the bottom of the vertical shaft is bolted into the support tube; the two mixing drums are respectively mounted on two sets of brackets; a control module is also provided on the base frame, and the control module is electrically connected to the liquid pump, the telescopic cylinder and the drive motor.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention provides two heat exchanger bodies, one upper and one lower, with connecting pipes at the inlet and outlet ends of their shell and tube sides. A central valve body and a side valve are provided at the middle and both ends of the connecting pipes. By adjusting the flow of the central valve body and the side valves, the two heat exchanger bodies can be connected in series to the heat exchange system, or one heat exchanger body can be connected to the heat exchange system while the other is first connected to the high-pressure liquid pump and then to the heat transfer components. This allows for the cleaning of impurities from the heat exchanger bodies without interrupting production.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] This invention provides a technical solution: In order to solve the prominent problems of high cost and impact on production continuity of existing heat exchanger impurity cleaning methods, this embodiment provides a new heat exchanger.

[0024] like Figure 1 , Figure 2 , Figure 10-12 As shown, the heat exchanger includes two heat exchanger bodies 1, a heat conduction assembly 2, a base frame 4, a vertical shaft 23, a stirring mechanism 24, and two parallel stirring drums 3, etc.

[0025] like Figure 2As shown, two heat exchanger bodies 1 are connected vertically via connecting devices. Connecting pipes 5 are installed at both the tube and shell sides of the two heat exchanger bodies 1, and a central valve body 6 is installed in the middle of the connecting pipe 5. Side valves 7 are also installed at both ends of the connecting pipe 5. When both heat exchanger bodies 1 are operating normally, to connect them in series, one end of the connecting pipe 5 at the tube and shell sides of the two heat exchanger bodies 1 is open, while the other end of the connecting pipe 5 is cut off via the central valve body 6. Then, the two side valves 7 of the cut connecting pipe 5 are connected to the heat exchange system, thus enabling heat exchange between two media at different temperatures through the two heat exchanger bodies 1. When it is necessary to clean impurities from a heat exchanger body 1, close the middle valve 6 of the connecting pipes 5 at both ends of the tube side and shell side. Then, connect the side pipe valve 7, which communicates with the working heat exchanger body 1, to the heat exchange system. Connect the other end of the heat exchanger body 1 to the heat transfer assembly 2 or directly to the output end of the high-pressure liquid pump. When connected to the high-pressure liquid pump, the tube side and shell side can be flushed with high-pressure water; when connected to the heat transfer assembly 2, the tube side and shell side can be acid-washed, alkaline-washed, etc. This setup reduces the impact of cleaning the heat exchanger on production.

[0026] like Figure 2 As shown, the heat-conducting components 2 are rotatably mounted on the connecting frame, which is connected to the connecting devices of the two heat exchanger bodies 1. Therefore, the heat-conducting components 2 are in a stable installation state. Furthermore, the state of the heat-conducting components 2 is adjustable, and they can move relative to the connecting frame. Therefore, the heat-conducting components 2 can be detachably mounted on the heat exchanger body 1 in the working state. That is, after removing the insulation layer of the heat exchanger body 1, the heat-conducting components 2 can directly contact the heat exchanger body 1, thereby utilizing the principle of heat conduction to increase the temperature of the pickling and alkaline cleaning solutions flowing through the heat-conducting components 2, changing the previous requirement of separate heating equipment. When pickling or alkaline cleaning of the heat exchanger body 1 is required, the output end of the heat-conducting components 2 is connected to a side valve 7.

[0027] like Figure 12As shown, both the vertical shaft 23 and the stirring drum 3 are mounted on the base frame 4, with the vertical shaft 23 positioned between the two stirring drums 3. The stirring mechanism 24 is connected to the vertical shaft 23. When the heat exchanger body 1 needs to be acid-washed or alkali-washed, the acid-washing or alkali-washing raw material is injected into the stirring drum 3, and then mixed by the stirring mechanism 24. Finally, the liquid delivery pipe 42 at the bottom of the stirring drum 3 is connected to the inlet end of the heat-conducting component 2 via the pipe body and the liquid pump 22, so that the acid-washing solution or alkali-washing solution can be delivered to the heat exchanger body 1 by the liquid pump 22. When the acid-washing solution or alkali-washing solution is output from one of the stirring drums 3, the stirring mechanism 24 rises along the vertical shaft 23 and detaches from that stirring drum 3. Then, the stirring mechanism 24 rotates around the vertical shaft 23 and descends to extend into the other stirring drum 3 to mix the material in the other stirring drum 3. By repeating the above steps, the materials in the two mixing drums 3 can be alternately mixed by the lifting and rotating of the stirring mechanism 24 around the vertical axis 23, thus avoiding the impact of the mixing of acid or alkali washing solution on the impurity removal process of the heat exchanger body 1.

[0028] like Figure 8 As shown, in order to fit the heat-conducting component 2 onto a heat exchanger body 1 and provide a channel for the flow of pickling liquid or alkaline cleaning liquid, the heat-conducting component 2 includes two arc-shaped chambers with a central angle of 180°. After the two arc-shaped chambers are placed in close contact with the heat exchanger body 1, their contact edges are connected by bolts, thereby making the arc-shaped chambers fit in close contact with the heat exchanger body 1.

[0029] like Figure 8 , Figure 9 As shown, the contact surfaces of the two arc-shaped chambers are both open, and a spiral plate 21 is provided on the inner side of each arc-shaped chamber. A spiral flow channel 18 is formed in the space formed by the two arc-shaped chambers through the two spiral plates 21. In addition, an inlet and outlet pipe communicating with the spiral flow channel 18 is provided at the ends of the two arc-shaped chambers that are far apart from each other. The liquid pump 22 is connected to one inlet and outlet pipe, and the other inlet and outlet pipe is connected to the side pipe valve 7. This allows the contact time between the liquid pump 22 and the heat exchanger body 1 to be extended through the spiral flow channel 18 when the liquid pump 22 is delivering pickling solution or alkaline washing solution. By adjusting the delivery pressure, it is convenient to heat the pickling solution or alkaline washing solution through the heat exchanger body 1.

[0030] like Figure 3 , Figure 4 , Figure 8As shown, in order to adjust the position of the heat-conducting component 2 according to the cleaning requirements and to fit it onto another heat exchanger body 1, frames 19 are provided on both arc-shaped chambers, and end shafts 20 are fixedly provided on the sides of the two frames 19 that are far apart from each other. The connecting frame includes a first support plate 8 and a second support plate 9 with adjustable spacing. End pipes 11 are fixedly provided on the top of the first support plate 8 and the second support plate 9. The two end pipes 11 are connected to the end shafts 20 through bearings, realizing the rotational connection between the arc-shaped chambers and the first support plate 8 and the second support plate 9. That is, after the first support plate 8 and the second support plate 9 drive the arc-shaped chamber away from the heat exchanger body 1, the arc-shaped chamber can be controlled to rotate 180° so that it faces the other heat exchanger body 1. Then the spacing of the first support plate 8 and the second support plate 9 can be controlled and adjusted so that the arc-shaped chamber fits onto the heat exchanger body 1.

[0031] like Figure 5 , Figure 6 As shown, a bottom cylinder 12 is vertically and rotatably connected to the bottom of the first support plate 8, and a locking post 13 is fixedly installed on the inner side wall of the bottom cylinder 12. A shaft 15 is vertically and rotatably connected to the bottom of the second support plate 9, and a slot 14 is provided on the side wall of the shaft 15. The shaft 15 extends into the bottom cylinder 12, and the locking post 13 is located in the slot 14. This arrangement achieves a stable connection between the first support plate 8 and the second support plate 9, and provides convenience for adjusting the distance between the two arc-shaped compartments.

[0032] like Figure 4 , Figure 7 As shown, the connecting frame also includes a support rod 10. Both ends of the support rod 10 are connected to the connecting devices of the two heat exchanger bodies 1. An arc-shaped plate 16 is fixedly installed in the middle of the support rod 10, and an annular plate 17 is fixedly installed on the arc-shaped plate 16. The bottom cylinder 12 extends into the space formed by the arc-shaped plate 16 and the annular plate 17. Therefore, the first support plate 8 and the second support plate 9 can be stably installed with the support of the support rod 10. After the arc-shaped chamber is placed close to the heat exchanger body 1, the bolts that pass through the annular plate 17 in the middle also pass through the bottom cylinder 12 and the insert shaft 15, restricting the position of the first support plate 8 and the second support plate 9. If it is necessary to adjust the position of the heat-conducting component 2, the bolts are removed to release the restriction between the bottom cylinder 12 and the insert shaft 15.

[0033] like Figure 14 , Figure 16 As shown, the stirring mechanism 24 uses a previously disclosed device, which is mounted on an annular end plate 34 at the end of the horizontal plate 28. A linear bearing 37 is mounted on the other end of the horizontal plate 28, and the linear bearing 37 is slidably sleeved on the vertical shaft 23. The bottom of the telescopic cylinder 26, which is located on the side of the vertical shaft 23, is connected to the base frame 4, and the telescopic end of the telescopic cylinder 26 is connected to the side plate 36. The side plate 36 is sleeved on the linear bearing 37 through a bearing connection. Therefore, when the telescopic cylinder 26 is working, the horizontal plate 28 can be raised and lowered, which facilitates adjusting the height of the stirring mechanism 24 to enter and exit the stirring drum 3.

[0034] like Figure 15 As shown, in order to ensure the stable installation of the stirring mechanism 24 after it extends into a stirring drum 3, two clamping arc plates 31 are bolted together on the vertical shaft 23. A brake rod 32 is fixedly installed on the side of each clamping arc plate 31 that is furthest from the other. A brake hole 35 is provided on the horizontal plate 28; after the stirring mechanism 24 extends into the stirring drum 3, one of the brake rods 32 extends into the brake hole 35, braking the horizontal plate 28 to prevent the stirring mechanism 24 from impacting the stirring drum 3.

[0035] like Figure 15 , Figure 16 As shown, to adjust the orientation of the stirring mechanism 24 after it rises, a drive motor 39 is mounted on the horizontal plate 28, and a drive gear 38 is fixedly mounted on the power output shaft of the drive motor 39. A fixed gear 30 is sleeved on the top of the vertical shaft 23. After the stirring mechanism 24 rises, the drive gear 38 and the fixed gear 30 mesh, and the drive motor 39 drives the stirring mechanism 24 to rotate, thereby driving the horizontal plate 28 and the stirring mechanism 24 to rotate, and positioning them directly above the other stirring drum 3. The drive motor 39 here can be a stepper motor, servo motor, etc.

[0036] like Figure 15 As shown, in order to stably mount the fixed gear 30 on the vertical shaft 23, a connecting pipe 33 is fixedly installed on the fixed gear 30, and a bolt is installed through the connecting pipe 33. The bolt is installed through a connecting hole 29 of the vertical shaft 23. There are multiple connecting holes 29, which are distributed along the height direction of the vertical shaft 23.

[0037] like Figure 10 , Figure 12 , Figure 13 As shown, multiple casters 40 are installed below the base frame 4 for easy adjustment of their position as needed. Two sets of brackets 25 are fixedly installed above the base frame 4, and two stirring drums 3 are respectively mounted on the two sets of brackets 25, ensuring stable installation of the stirring drums 3 on the base frame 4. Additionally, a liquid inlet pipe 41 is installed on the top of the stirring drum 3, which can be connected to another liquid pump 22 for liquid input. A support pipe 27 is fixedly installed between the two sets of brackets 25, and the bottom of the vertical shaft 23 is bolted into the support pipe 27. A control module 43 is also installed on the base frame 4. The control module 43 is equipped with corresponding components according to existing technology to electrically connect to the liquid pump 22, the telescopic cylinder 26, and the drive motor 39, and to control the operation of the liquid pump 22, the telescopic cylinder 26, and the drive motor 39. The control module 43 is also electrically connected to the mains power supply for operation.
