Description

Technical Field

[0001] This invention relates to the field of heat exchanger technology, specifically to a high-temperature heat pipe type carbon black rapid cooling heat exchange device. Background Technology

[0002] In the production process of carbon black using the oil furnace method, fuel oil is injected into the carbon black reactor and burned to generate a high temperature of nearly 2000 degrees Celsius. Then, raw material oil is injected, which undergoes incomplete combustion and pyrolysis at this high temperature to produce carbon black. During the termination of the reaction, a large amount of quench water is used, resulting in water waste and significant heat loss.

[0003] A heat pipe heat exchanger uses a liquid working fluid at the bottom of the heat pipe to absorb heat from the flue gas and vaporize. The working fluid vapor flows to the upper part of the high-temperature heat pipe, releases heat to the water in the casing, and then condenses into liquid working fluid. Under the action of gravity, the liquid working fluid flows down the inner wall of the high-temperature heat pipe from the top to the bottom. The liquid working fluid then exchanges heat with the carbon black flue gas outside the pipe again and vaporizes into steam. The working fluid inside the pipe cycles repeatedly to absorb heat, vaporize, rise, condense, fall, and absorb heat.

[0004] The heat exchange efficiency of heat pipe heat exchangers in the prior art can be improved by adding fins, but adding fins makes it difficult to assemble the dust removal mechanism. Summary of the Invention

The upper part of the heat pipe body is located inside the heat exchange box, and the lower part is located inside the carbon black flue gas passage box. The portion of the heat pipe body located inside the carbon black flue gas passage box is designated as a heating section, which contains a working fluid. The heating section has at least two recessed portions along its circumference. The device also includes: The heat exchange fins have a portion located inside the concave part and a portion exposed outside the concave part and protruding from the outer surface of the heat pipe body. In the heat exchange state, the heat exchange fins are used to enhance the heat exchange between the inside and outside of the heating section. The heat exchange fins have a cutter head on one side inside the concave portion. The retraction structure is located below the carbon black flue gas passage box and is used to push the heat exchange fins radially away from the concave portion until the cutter head is located on the outer circumference of the heat pipe body. The movable structure is located below the carbon black flue gas passage box. In the ash removal state, the movable structure is used to drive the heat exchange fins to move circumferentially along the heating section and scrape off the carbon black impurities on the outer surface of the heating section with a blade.

[0007] Furthermore, a base is provided at the lower end of the heat exchange fins; The retraction structure includes a conical head, the surface of which is provided with a track, and the lower end of the base is provided with a limiting slider that is adapted to the track.

[0009] Furthermore, fixed fins are also fixed around the heating section, with the fixed fins located between two adjacent heat exchange fins; The base is fixed to the lower end of the heat exchange fins; The heat exchange fins are provided with impact heads on their sides.

[0010] Furthermore, the groove of the concave portion is designed as a trumpet-shaped structure, and elastic scrapers are provided on both sides of the inner wall of the trumpet-shaped structure.

[0011] Furthermore, the bottom surface of the carbon black flue gas passage box has a through hole for passing through the heat exchange fins, and the area on the heat exchange fins opposite to the through hole has a clearance groove. A sealing plate is provided on the upper side of the clearance groove, and the sealing plate has a through groove for the heat exchange fins to slide radially.

[0012] Furthermore, a second guide rod is inserted into the base along the radial direction of the heating section, and a rotating disk is fixed at one end of the multiple second guide rods near the center of the heating section. The rotating disk is rotatably mounted on the upper end of the fixed rod, and the lower end of the fixed rod passes through the conical head and the columnar part. A second spring is fitted onto the other end of the second guide rod.

[0013] Furthermore, the carbon black flue gas passage box has a carbon black inlet at one end, and a bypass pipe is installed on the carbon black inlet.

[0021] 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.

[0022] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0023] The following is based on Figures 1-17 This invention describes a high-temperature heat pipe carbon black rapid cooling heat exchange device provided in an embodiment of the present invention.

[0024] Example 1, please refer to Figures 1-3 This invention provides a high-temperature heat pipe type carbon black rapid cooling heat exchange device, including a carbon black flue gas passage box 4, a heat exchange box 3 located above the carbon black flue gas passage box 4, and a heat pipe body 5. The heat pipe body 5 is configured from bottom to top as a heating section 51, a transition section 52, and a condensation section 53. The transition section 52 is welded between the carbon black flue gas passage box 4 and the heat exchange box 3. The heating section 51 is the lower part of the heat pipe body 5 and is located inside the carbon black flue gas passage box 4. The condensation section 53 is the upper part of the heat pipe body 5. The heat exchanger is located in the heat exchange box 3. The working fluid is placed in the lower part of the heating section 51. After absorbing the heat of the carbon black flue gas in the heating section 51, the working fluid evaporates. The steam rises through the transition section 52 to the condensing section 53. It is called the condensing section 53 because a jacket 15 is set outside this section. Flowing water is introduced into the jacket 15 so that the steam in the condensing section 53 exchanges heat with the flowing water in the jacket 15. At this time, the steam in the condensing section 53 condenses and falls back into the heating section 51. The flowing water becomes hot steam and is discharged.

[0025] Preferably, the jacket 15 has a water inlet 151 near the lower end and a steam outlet 152 near the upper end. The water inlets 151 in the same row share a manifold 16, multiple manifolds 16 share a hot water inlet pipe 1, the steam outlets 152 in the same row share a manifold 7, and multiple manifolds 7 share a steam exhaust pipe 2.

[0026] To enhance the heat exchange effect of the heating section 51 on the carbon black flue gas and the liquid working fluid, at least two recessed portions 511 are provided circumferentially in the heating section 51. This embodiment refers to... Figure 3 In this embodiment, three recesses 511 are provided, and a fin mechanism 6 is provided. The fin mechanism 6 includes heat exchange fins 61. A portion of the heat exchange fins 61 is located inside the recesses 511, and a portion is exposed outside the recesses 511 and protrudes from the outer surface of the heat pipe body 5. In the heat exchange state, the heat exchange fins 61 are used to enhance the heat exchange effect between the working fluid inside the heating section 51 and the external carbon black flue gas, and ensure rapid cooling of the carbon black flue gas.

[0027] Combination Figures 3-6As shown, after long-term use, a certain amount of carbon black particles will accumulate on the outer circumference of the heating section 51, which will reduce the heat conduction effect of the heating section 51. Therefore, a retraction structure and a moving structure are provided for the heat exchange fins 61. A cutter head 611 is provided on one side of the heat exchange fins 61 located in the concave part 511. The retraction structure is located below the carbon black flue gas passage box 4. A mechanical box 12 is actually set below the carbon black flue gas passage box 4. The retraction structure is installed in the mechanical box 12. The retraction structure is used to push the heat exchange fins 61 radially away from the concave part 511 until the cutter head 611 is located on the outer circumferential trajectory of the heat pipe body 5. The moving structure is located below the carbon black flue gas passage box 4 and inside the mechanical box 12. In the ash cleaning state, the moving structure is used to drive the heat exchange fins 61 to move circumferentially along the heating section 51 and scrape off the carbon black impurities on the outer surface of the heating section 51 by the cutter head 611.

[0028] Therefore, the heat exchange fins 61 of the high-temperature heat pipe carbon black rapid cooling heat exchange device provided in this embodiment of the invention can play a role in heat conduction under heat exchange conditions, thereby improving the heat exchange efficiency between the working fluid and the carbon black flue gas. In addition, under the ash removal condition, the carbon black on the outer surface of the heating section 51 can be scraped off to maintain the heat conduction effect of the heating section 51, thereby ensuring the continuous operation of the heating section 51.

[0029] To facilitate the radial and circumferential movement of the heat exchange fins 61, a base 62 is provided at the lower end of the heat exchange fins 61. The aforementioned moving structure and retraction structure are essentially composed of a power block 10. The retraction structure formed by the power block 10 includes a conical head 101. A track 102 is provided on the surface of the conical head 101. The track 102 is arranged along the slope of the conical head 101. A limiting slider 621 adapted to the track 102 is provided at the lower end of the base 62. When the conical head 101 rises, the limiting slider 621 can slide within the track 102, thereby moving the limiting slider 621 radially along the heat pipe body 5. At this time, the limiting slider 621 pushes the heat exchange fins 61 away from the concave portion 511 through the base 62.

[0030] The moving structure formed by the power block 10 includes a columnar part 103, which is fixed to the lower end of the conical head 101. The outer surface of the columnar part 103 is provided with a second track 104, which is a groove structure formed by a positive spiral and a negative spiral. The upper end of the second track 104 is connected to the opposite first track 102. When the limiting slider 621 pushes the heat exchange fins 61 away from the concave part 511 through the base 62, the columnar part 103 continues to rise. At this time, the heat exchange fins 61 no longer move radially along the heating section 51. The limiting slider 621 enters the second track 104. Due to the action of the positive and negative spirals, the limiting slider 621 can drive the heat exchange fins 61 to move back and forth along the axial direction of the heat pipe body 5, so that the heat exchange fins 61 can scrape off the carbon black on the heating section 51.

[0031] Preferably, a lifting plate 17 is installed inside the mechanical housing 12, and the columnar part 103 is fixed on the lifting plate 17. The lifting plate 17 can actively lift and lower to drive the columnar part 103 to lift and lower, and the columnar part 103 and the conical head 101 lift and lower synchronously.

[0032] The specific details of track 2 104 are given below. For example, in this embodiment, three sets of heat exchange fins 61 are provided, referring to... Figures 6-8 As shown, the central angle between two adjacent heat exchange fins 61 is 120°, the spiral angle of the positive spiral is 60°, and the spiral angle of the negative spiral is 120°. When the limiting slider 621 enters the positive spiral groove from the track 102, the positive spiral groove can drive the heat exchange fins 61 to rotate 60° in the positive direction by pushing the limiting slider 621. As the columnar part 103 continues to rise, the limiting slider 621 enters the negative spiral groove. At this time, the negative spiral groove can drive the heat exchange fins 61 to rotate 120° in the opposite direction by pushing the limiting slider 621, thereby ensuring that the maximum sweeping angle of each heat exchange fin 61 is 120° (actually less than 120°, because the angle occupied by the concave part 511 also needs to be subtracted), thereby enabling the three cutter heads 611 to scrape off the carbon black on the outer surface of the heating section 51 from all directions.

[0033] To ensure the scraping effect, the lifting plate 17 is set to reciprocate up and down, thereby realizing the heat exchange fins 61 repeatedly to ensure the scraping effect. However, its reciprocating motion should be the reciprocating motion of the limiting slider 621 within the second track 104. That is, the first height L1 of the first rise of the lifting plate 17 is used to push the heat exchange fins 61 out of the concave part 511 through the conical head 101 and the first track 102. The second height L2 of the second rise of the lifting plate 17 is used to realize the first reciprocating motion of the heat exchange fins 61 through the columnar part 103 and the second track 104. Then the lifting plate 17 descends for the first time, and the descent height is L2, thereby realizing the second reciprocating motion of the heat exchange fins 61. Then the lifting plate 17 moves up and down at a height of L2 to realize the repeated dust removal action of the heat exchange fins 61.

[0034] Combination Figures 7-9 As shown, preferably, a bracket 11 is installed below the mechanical box 12. The bracket 11 is also equipped with a cylinder 8 for driving the lifting plate 17 to rise and fall. By controlling the extension and retraction length of the cylinder 8, the lifting height of the lifting plate 17 can be controlled.

[0035] In actual use, carbon black impurities will also adhere to the heat exchange fins 61, so the heat exchange fins 61 also need to be cleaned. In this embodiment, the heat exchange fins 61 can move up and down while being cleaned circumferentially along the heating section 51. When they move downwards, they can collide with the bottom surface of the carbon black flue gas passing through the box 4, thereby achieving autonomous cleaning of the heat exchange fins 61. Specifically, a spring 63 is fixed between the lower end of the heat exchange fins 61 and the base 62, and a first guide is sleeved inside the spring 63. A fixing ring 91 is fixed at the upper end of the heating section 51 of the rod 64. A concave-convex rail 92 is provided on the lower surface of the fixing ring 91. An outer retaining ring 95 is provided around the concave-convex rail 92. An inner retaining ring 93 is provided inside the concave-convex rail 92. A radial rail 94 is provided in the area where the inner retaining ring 93 is opposite to the concave area of ​​the concave-convex rail 92. A slider 20 is provided in the middle area of ​​the upper end of the heat exchange fin 61. A ball bearing 19 is provided at the upper end of the slider 20. The ball bearing 19 can slide on the radial rail 94 and the concave-convex rail 92.

[0036] When the heat exchange fins 61 move radially, the balls 19 move on the radial rails 94. When the heat exchange fins 61 rotate around the center of the heat pipe body 5, the balls 19 move on the concave and convex rails 92.

[0037] A through hole is provided on the bottom surface of the carbon black flue gas passage box 4 for passing through the heat exchange fins 61. A relief groove 67 is provided on the area opposite to the through hole on the heat exchange fins 61. A sealing plate 68 is provided on the upper side of the relief groove 67. The sealing plate 68 is provided with a through groove for the heat exchange fins 61 to slide radially. The sealing plate 68 is used to block the through hole on the bottom surface of the carbon black flue gas passage box 4.

[0038] In this embodiment, when the heat exchange fins 61 are being cleaned, they are essentially rotating around the heating section 51. During this rotation, the upper end is constantly being squeezed by the concave and convex rails 92, thus achieving up-and-down movement. When the convex area is reached, the heat exchange fins 61 move downward, compressing the spring 63, allowing the upper side of the positioning groove 67 to impact the bottom surface of the carbon black flue gas passing through the box 4, achieving the effect of vibration and ash removal. Conversely, when the concave area is reached, the spring 63 rebounds, and the heat exchange fins 61 move upward.

[0039] It should be noted that the reason for setting the clearance groove 67 is to reduce the diameter of the through hole opened on the bottom surface of the carbon black flue gas passage box 4. Due to the setting of the clearance groove 67, the through hole only needs a small diameter to allow the heat exchange fin 61 to pass through. However, the diameter of the through hole is smaller than the diameter of the sealing plate 68, but larger than the diameter of the circle formed by the bottom of the three clearance grooves 67 after the heat exchange fin 61 exits from the concave part 511, so as to ensure that the heat exchange fin 61 can smoothly exit from the concave part 511.

[0040] Preferably, a space is reserved between the lower end of the heating section 51 and the sealing plate 68.

[0041] Preferably, the upper end of the first guide rod 64 is fixed on the heat exchange fins 61, and the lower end is inserted into the base 62.

[0042] like Figure 10 In order to enhance the vibration effect of the heat exchange fins 61 and improve their dust removal ability, a portion of the heat exchange fins 61 near the center of the heating section 51 is designated as a hard part 612, and the cutter head 611 is located on the side of the hard part 612 near the center of the heating section 51; a portion of the heat exchange fins 61 away from the center of the heating section 51 is designated as an elastic part 613.

[0043] In actual use, when the entire heat exchange fin 61 impacts the carbon black flue gas passing through the bottom surface of the box 4, the elastic part 613 can increase its vibration frequency, thereby improving the dust removal effect, while the hard part 612 can ensure the dust removal effect of the cutter head 611.

[0044] Preferably, the hardened part 612 is made of high-temperature resistant stainless steel.

[0045] Preferably, the elastic part 613 is made of spring steel.

[0046] Preferably, the outer diameter of the heating section 51 is 150 mm, the depth of the concave portion 511 is 20 mm, and the width is adapted to the thickness of the hard portion 612 of the heat exchange fin 61, both being 5 mm.

[0047] Preferably, the groove of the concave portion 511 is designed as a funnel-shaped structure, and elastic scrapers 21 are provided on both sides of the inner wall of the funnel-shaped structure. The elastic scrapers 21 have two functions: first, they can prevent the carbon black scraped from the outer surface of the heating section 51 by the heat exchange fins 61 from entering the concave portion 511; second, they can scrape off the carbon black on the outer surface of the heat exchange fins 61 when the heat exchange fins 61 are reinserted into the concave portion 511. In summary, the elastic scrapers 21 directly remove the carbon black from the surface of the blade 611, thus avoiding the backflow phenomenon from the source.

[0048] Optionally, the elastic scraper 21 is made of Inconel alloy.

[0049] Furthermore, the slot expansion angle can be selected as 10°-15° (too small an angle will not guide insertion, and too large an angle will affect heat conduction and contact).

[0050] like Figure 8As shown, in order to ensure that the heat exchange fins 61 can move radially along the heat pipe body 5 when the conical head 101 moves upward and applies a thrust to the limiting slider 621, in this embodiment, a second guide rod 65 is inserted into the base 62 along the radial direction of the heating section 51. A rotating disk 66 is fixed at one end of the multiple second guide rods 65 near the center of the heating section 51. The rotating disk 66 is rotatably mounted on the upper end of the fixed rod 661. The lower end of the fixed rod 661 passes through the conical head 101 and the columnar part 103 and is fixed in the machine box 12. A spring 651 is sleeved on the other end of the second guide rod 65.

[0051] On the one hand, the second guide rod 65 is supported by the rotating disk 66 and the fixed rod 661; on the other hand, multiple second guide rods 65 can also be connected into one unit by the rotating disk 66.

[0052] When the conical head 101 moves upward and opens the base 62, causing the base 62 and heat exchange fins 61 to move outward along the radial direction of the heat pipe body 5, the second guide rod 65 acts as a guide. At this time, the base 62 compresses the second spring 651. When the base 62 and heat exchange fins 61 rotate along the heat pipe body 5, the second guide rod 65 rotates accordingly, and the rotating disk 66 also rotates accordingly. Conversely, when the conical head 101 moves downward, the second spring 651 rebounds, and the base 62 and heat exchange fins 61 reset. After the heat exchange fins 61 reset, they should be re-embedded into the concave part 511.

[0053] Preferred, such as Figure 1 A carbon black inlet 14 is provided at one end of the carbon black flue gas passage box 4. In order to ensure that the carbon black scraped off by the cutter head 611 can be removed, a bypass pipe 13 is installed on the carbon black flue gas inlet 14. A solenoid valve is provided on the bypass pipe 13. The solenoid valve is used to control the opening and closing of the bypass pipe 13. When the bypass pipe 13 is open, it is used to introduce air into the carbon black flue gas passage box 4. During the ash removal stage, the airflow introduced by the bypass pipe 13 can form a ash blowing effect. The air is used to enhance the removal effect of impurities after being scraped off by the cutter head 611, and the scraped impurities are discharged from the flue gas outlet of the carbon black flue gas passage box 4.

[0054] During use (operation), in the heat exchange stage, carbon black flue gas enters the interior of the carbon black flue gas passage box 4 from the carbon black flue gas inlet 14, and exchanges heat with the working fluid through the heating section 51 and the heat exchange fins 61 on the heating section 51, causing the temperature of the carbon black flue gas to drop rapidly. The temperature of the working fluid in the heating section 51 rises and forms steam. The steam rises to the condensation section 53 and exchanges heat with the water in the jacket 15, causing the water to turn into steam and be discharged. The steam in the condensation section 53 condenses and returns to the heating section 51 to exchange heat with the carbon black flue gas.

[0055] After the device has been used for a period of time, when the temperature difference between the inlet and outlet of the heat exchange box 3 is lower than the preset value (e.g., 50℃) or after the device has been running continuously for 24 hours, the dust removal procedure is started. First, the carbon black flue gas is stopped from entering the carbon black inlet 14, the bypass pipe 13 is opened, and high-pressure gas is introduced. At the same time, the cylinder 8 is controlled to work. At this time, the lifting plate 17 drives the power block 10 to rise a distance L1. At this time, under the push of the conical head 101, the limiting slider 621 can slide in the track 102. Under the guidance of the first guide rod 64, the limiting slider 621 pushes the heat exchange fins 61 to disengage from the concave part 511 through the base 62. Bead 19 enters the concave area of ​​the concave-convex rail 92 from the radial rail 94. As the lifting plate 17 continues to rise, the limiting slider 621 enters the positive spiral groove from the first rail 102. The positive spiral groove can drive the heat exchange fins 61 to rotate 60° in the forward direction by pushing the limiting slider 621. As the columnar part 103 continues to rise, the limiting slider 621 enters the reverse spiral groove. At this time, the reverse spiral groove can drive the heat exchange fins 61 to rotate 120° in the reverse direction by pushing the limiting slider 621, thereby ensuring that the maximum sweep angle of each heat exchange fin 61 is 120°, so that the three cutter heads 611 can scrape off the carbon black on the outer surface of the heating section 51 in all directions.

[0056] To ensure the scraping effect, the lifting plate 17 is set to reciprocate up and down, thereby realizing the heat exchange fins 61 repeatedly to ensure the scraping effect. However, its reciprocating motion should be the reciprocating motion of the limiting slider 621 within the second track 104. That is, the first height L1 of the first rise of the lifting plate 17 is used to push the heat exchange fins 61 out of the concave part 511 through the conical head 101 and the first track 102. The second height L2 of the second rise of the lifting plate 17 is used to realize the first reciprocating motion of the heat exchange fins 61 through the columnar part 103 and the second track 104. Then the lifting plate 17 descends for the first time, and the descent height is L2, thereby realizing the second reciprocating motion of the heat exchange fins 61. Then the lifting plate 17 moves up and down at a height of L2 to realize the repeated dust removal action of the heat exchange fins 61.

[0057] Of course, during the process of rotating and cleaning the heat exchange fins 61, when the upper end of the heat exchange fins 61 reaches the convex area, the heat exchange fins 61 are pushed downwards, compressing the spring 63, and causing the upper edge of the groove 67 to impact the carbon black flue gas passing through the bottom of the box 4, achieving the effect of vibration and ash removal. Conversely, when the upper end of the heat exchange fins 61 reaches the concave area, the spring 63 rebounds, and the heat exchange fins 61 move upwards. The ash removal is carried out by the vibration generated by the up-and-down movement of the heat exchange fins 61. The removed carbon black is blown away by the high-pressure airflow and discharged from the flue gas outlet.

[0058] Example 2 differs from Example 1 in that a fixed fin 69 is fixed to the periphery of the heating section 51. The fixed fin 69 is welded to the heating section 51 and is located between two adjacent heat exchange fins 61. (Refer to...) Figures 11-14 As shown, three fixed fins 69 and three heat exchange fins 61 are distributed at intervals, for a total of six fins. In this embodiment, adjacent fixed fins 69 and heat exchange fins 61 collide with each other to clean the fins, and in this embodiment, the heat exchange fins 61 no longer move up and down.

[0059] Specifically, the base 62 is directly fixed to the lower end of the heat exchange fins 61, and a collision head 18 is provided on the side of the heat exchange fins 61.

[0060] In this embodiment, to ensure the scraping effect, the lifting plate 17 is designed to reciprocate up and down, thereby achieving multiple reciprocations of the heat exchange fins 61 and ensuring the scraping effect. However, its reciprocating motion should be the reciprocating motion of the limiting slider 621 within the second track 104. That is, the first height L1 of the first rise of the lifting plate 17 is used to push the heat exchange fins 61 out of the concave portion 511 through the conical head 101 and the first track 102, and the second height L2 of the second rise of the lifting plate 17 is used to push the heat exchange fins 61 out of the concave portion 511 through the columnar portion 103 and the concave portion 104. Track 2 104 realizes the first reciprocating motion of heat exchange fin 61. Then, the lifting plate 17 descends for the first time at a height of L2, thus realizing the second reciprocating motion of heat exchange fin 61. Subsequently, the lifting plate 17 moves up and down at a height of L2 to realize the repeated dust removal action of heat exchange fin 61. At the same time, when heat exchange fin 61 rotates to the corner area of ​​track 2 104, the collision head 18 on it can hit the fixed fin 69, thereby ensuring the removal of carbon black from the fixed fin 69 and the heat exchange fin 61 itself.
