Description

Technical Field

[0001] The present invention relates to the technical field related to heat exchange, and in particular to an energy absorption device based on heat exchange and application thereof in olefin preparation. Background Art

[0002] During the preparation of olefins, a large amount of heat is released, and the heat exchange device can utilize the heat. Heat exchange is the process of heat transfer between two objects or parts of the same object caused by temperature difference. Heat exchange is generally completed through three methods: heat conduction, heat convection and heat radiation.

[0003] During the use of the existing heat exchange device, high-temperature gas is introduced into the heat exchange device, and then cold water is introduced into the serpentine water pipe. The high-temperature gas transfers heat to the serpentine water pipe, and then the cold water in the serpentine water pipe can be heated. For the high-temperature gas with impurities, the impurities will adhere to the outer wall of the serpentine water pipe at high temperature, hindering the temperature exchange between the pipe and the high-temperature gas, thereby affecting the heat exchange efficiency;

[0004] In order to solve this problem, the prior art usually uses a scraper to move up and down to scrape off impurities on the outer wall of the serpentine water pipe. However, when the scraper in the prior art moves upward, it will also scrape off impurities remaining on the outer wall of the serpentine water pipe. After a long time, more impurities will accumulate on the top of the scraper, and the impurities on the top of the scraper cannot be cleaned, causing the impurities on the top of the scraper to continue to adhere to the outer wall of the serpentine water pipe when the scraper moves downward, thereby affecting the cleaning effect of the serpentine water pipe. At the same time, scale will also adhere to the inner wall of the serpentine water pipe. If the scale is not cleaned, the accumulated scale will also affect the heat exchange efficiency of the high-temperature gas to the inside of the water pipe. Summary of the invention

[0039] See also Figure 1-12 In an embodiment of the present invention, an energy absorption device based on heat exchange includes a shell 1 and a serpentine absorption tube 4 arranged inside the shell 1, the two ends of the top of the shell 1 are respectively connected with an air inlet pipe 2 and an air outlet pipe 3, a lifting component 5 is arranged inside the shell 1, and two ends of the shell 1 are symmetrically arranged with connecting seats 6, the two connecting seats 6 are connected by the lifting component 5, and two scrapers 7 are arranged between the two connecting seats 6. When the lifting component 5 drives the connecting seat 6 to move downward, the scraper 7 cleans the attachments outside the serpentine absorption tube 4;

[0040] Two sliding seats 8 are provided for sliding inside the connecting seat 6, a first spring 9 is provided between the sliding seat 8 and the inner wall of the connecting seat 6, a push block 10 is fixedly provided on the side of the sliding seat 8 away from the scraper 7, a connecting assembly 12 is provided on the top of the connecting seat 6, and a reset member 13 and an ejector 14 are provided on the top and bottom of the inner wall of the shell 1 respectively. When the connecting seat 6 moves downward to the position of the ejector 14, the ejector 14 acts on the connecting assembly 12, and the two sliding seats 8 are moved away, thereby making the two scrapers 7 away from the serpentine absorption tube 4. When the connecting seat 6 moves upward to the position of the reset member 13, the reset member 13 pushes the two push blocks 10 to move inward, thereby pushing the two scrapers 7 close to the serpentine absorption tube 4;

[0041] A plurality of evenly distributed vertical rods 15 are respectively arranged on the front and back sides of the serpentine absorption tube 4, a plurality of evenly arranged knocking components 16 are arranged on one end of the scraper 7 away from the serpentine absorption tube 4, and a plurality of flipping members 17 cooperating with the knocking components 16 are arranged on the side of the vertical rod 15 close to the scraper 7. When the scraper 7 moves downward, the flipping members 17 act on the knocking components 16, and the knocking components 16 knock on the outer wall of the serpentine absorption tube 4 to generate vibration;

[0042] A mounting seat 11 is fixedly arranged on one side of the connecting seat 6 away from the push block 10, and both ends of the scraper 7 are respectively fixedly arranged inside the two mounting seats 11. The mounting seats 11 are arranged to fix the scraper 7;

[0043] The two scrapers 7 are provided with corresponding semicircular grooves on opposite sides thereof, and the semicircular grooves are matched with the serpentine absorption tube 4, and the vertical rod 15 and the knocking assembly 16 are both corresponding to the semicircular grooves;

[0044] The top and bottom of the vertical rod 15 are fixed inside the housing 1 through the cross rod 19;

[0045] Two connecting rods 18 are slidably disposed at both ends of the sliding seat 8, and the connecting rods 18 are fixedly disposed inside the connecting seat 6. The sliding seat 8 is slidably disposed inside the connecting seat 6 through the connecting rods 18;

[0046] The serpentine absorption tube 4 is located inside the cavity formed by the semicircular grooves in the two scrapers 7. When in use, the high-temperature gas is passed into the shell 1 through the air inlet pipe 2, and the cold water is passed into the serpentine absorption tube 4. The high-temperature gas conducts heat to the serpentine absorption tube 4, thereby heating the cold water in the serpentine absorption tube 4. It is necessary to clean the impurities on the outer wall of the serpentine absorption tube 4. The lifting component 5 drives the connecting seat 6 and the two scrapers 7 to move downward, and the scraper 7 can scrape and clean the impurities on the outer wall of the serpentine absorption tube 4. As the connecting seat 6 descends, when the connecting seat 6 moves to the position of the ejector 14, the ejector 14 acts on the connecting component 12, and the connecting component 12 moves upward to release the limit of the two adjacent sliding seats 8. The sliding seat 8 moves outward under the action of the first spring 9, and the two scrapers 7 move away from the serpentine absorption tube 4. At the same time, the lifting component 5 is again The connecting seat 6 and the scraper 7 are driven to move upward. When the connecting seat 6 moves to the position of the reset member 13, the reset member 13 acts on the push block 10, so that the push block 10 drives the sliding seat 8 to move inward, squeezes the first spring 9, and the two scrapers 7 move inward and reset. When the sliding seat 8 moves to the innermost position, it is re-limited under the action of the connecting component 12, so that the scraper 7 can clean the impurities on the outer wall of the serpentine absorption tube 4 when moving downward next time. Under the action of the connecting component 12, the ejector 14 and the reset member 13, the scraper 7 can clean the impurities on the outer wall of the serpentine absorption tube 4 only when it is moving downward, thereby preventing the scraper 7 from scraping the impurities on the outer wall of the serpentine absorption tube 4 and accumulating them on the top of the scraper 7 when it is moving upward, causing the impurities on the top of the scraper 7 to continue to adhere to the outer wall of the serpentine absorption tube 4 when the scraper 7 moves downward, affecting the cleaning effect of the serpentine absorption tube 4;

[0047] At the same time, during the downward movement of the scraper 7, the knocking component 16 contacts the flip part 17, and the knocking component 16 can knock the serpentine absorption tube 4 to make it vibrate. In addition, the number of flip parts 17 is large, so during the descent of the scraper 7, vibration can be continuously generated, thereby achieving the effect of simultaneously processing the scale attached to the inner wall of the serpentine absorption tube 4 and the impurities attached to the outer wall of the serpentine absorption tube 4, avoiding the accumulation of scale on the inner wall of the serpentine absorption tube 4 affecting the heat exchange efficiency of the high-temperature gas to the inner wall of the serpentine absorption tube 4, and improving the cleaning effect of impurities outside the serpentine absorption tube 4.

[0048] See also Figure 3 The lifting assembly 5 includes a lifting motor 51, a threaded rod 52, two fixed rods 53 and a lifting plate 54. The lifting motor 51 is fixedly arranged on the top of the housing 1, and the output shaft is connected to the threaded rod 52. The threaded rod 52 is rotatably arranged inside the housing 1. The two fixed rods 53 are symmetrically arranged on both sides of the threaded rod 52 and fixedly arranged inside the housing 1. The middle part of the lifting plate 54 is threadedly connected to the outside of the threaded rod 52. The two ends of the lifting plate 54 are respectively slidably sleeved on the outside of the two fixed rods 53. The two connecting seats 6 are respectively fixedly arranged on both sides of the lifting plate 54.

[0049] By starting the lifting motor 51 , the threaded rod 52 is driven to rotate, and at the same time, under the action of the two fixing rods 53 , the lifting plate 54 can drive the two connecting seats 6 to move up and down.

[0050] See also Figure 6-Figure 8 The connecting assembly 12 includes a top plate 121, guide rods 122 are slidably arranged inside both ends of the top plate 121, the bottom of the guide rod 122 is fixedly connected to the connecting seat 6, a second spring 123 is arranged between the bottom of the top plate 121 and the top of the connecting seat 6, connecting blocks 124 are fixedly arranged at both ends of the bottom of the top plate 121, and a connecting groove 125 matching with the connecting block 124 is opened on the top of the sliding seat 8;

[0051] The reset member 13 is composed of a mounting plate 131 and two extrusion blocks 132. The extrusion blocks 132 are fixedly arranged at both ends of the bottom of the mounting plate 131. A groove 133 is opened in the middle of the mounting plate 131, and the groove 133 is matched with the top plate 121.

[0052] As the connection seat 6 descends, when the connection seat 6 moves to the position of the ejector 14, the ejector 14 acts on the top plate 121. As the connection seat 6 continues to descend, the top plate 121 moves upward along the guide rod 122, and the second spring 123 stretches until the top plate 121 drives the connection block 124 to disengage from the inside of the connection groove 125, thereby releasing the limit of the two adjacent sliding seats 8, and the sliding seats 8 move outward under the action of the first spring 9;

[0053] When the connecting seat 6 moves upward to the position of the reset member 13, the extrusion block 132 acts on the push block 10. As the connecting seat 6 continues to rise, the extrusion block 132 pushes the push block 10 to drive the sliding seat 8 to move inward. At this time, the first spring 9 is squeezed. When the sliding seat 8 moves inward, it acts on the connecting block 124. The connecting block 124 is forced to move upward, and the second spring 123 is stretched until the connecting block 124 corresponds to the connecting groove 125. The connecting block 124 is stuck in the connecting groove 125 under the action of the second spring 123, and the sliding seat 8 is limited again. The setting of the groove 133 makes the end of the top plate 121 staggered with the mounting plate 131, so as to avoid the mounting plate 131 acting on the top plate 121 and affecting its use.

[0054] See also Fig.10 and Fig.11 The knocking assembly 16 includes a bracket 161 and a fixed plate 162. The bracket 161 is rotatably arranged inside the scraper 7. The fixed plate 162 is fixedly arranged at the bottom of the scraper 7. A knocking ball 163 is arranged at the bottom of the bracket 161. A third spring 164 is arranged between the bracket 161 and the fixed plate 162.

[0055] When the bracket 161 touches the flip piece 17, as the scraper 7 moves downward, the bracket 161 flips over, the knocking ball 163 moves away from the serpentine absorption tube 4, and the third spring 164 is stretched. When the bracket 161 is offset from the flip piece 17, the bracket 161 is reset under the action of the third spring 164, and the knocking ball 163 acts on the serpentine absorption tube 4 to knock on the serpentine absorption tube 4, thereby processing the scale attached to the inner wall of the serpentine absorption tube 4 and the impurities attached to the outer wall of the serpentine absorption tube 4.

[0056] See also Fig.12 The flip member 17 includes a fixed block 171, a flip plate 172 is rotatably provided on the top of the fixed block 171, and a fourth spring 173 is provided between the bottom of the flip plate 172 and the fixed block 171;

[0057] When the scraper 7 moves downward, the bracket 161 touches the flip plate 172 from top to bottom. At this time, the flip plate 172 cannot move under the action of the fixed block 171, so that the bracket 161 can be flipped. When the scraper 7 moves upward, the bracket 161 touches the flip plate 172 from bottom to top, and the flip plate 172 flips upward. The fourth spring 173 is stretched by force. When the bracket 161 and the flip plate 172 are misaligned, the flip plate 172 moves downward under the action of the fourth spring 173 and is re-positioned on the top of the fixed block 171. The flip plate 172 can rotate to avoid damage caused by hard contact between the bracket 161 and the flip plate 172 when it moves upward.
