Technical Field
[0001] This application relates to the technical field of heat exchangers, especially the flash bottom oil and the second normal heat exchanger in the middle distillate fraction. Background Art
[0002] Petrochemical machinery is also known as petrochemical equipment. The so-called petrochemical equipment is the abbreviation of petroleum and chemical equipment. Petrochemical equipment refers to the general term of equipment used in a series of processes from oil drilling and production to transportation until it is processed into chemical products. It mainly includes static equipment such as tower equipment, heat exchangers, reactors, storage tanks and various shell equipment, as well as dynamic equipment for transporting media.
[0003] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. In the field of petrochemical machinery, a heat exchanger is used to transfer and adjust energy. During high-temperature refining processes, a heat exchanger can quickly cool the heated materials to control the reaction rate and product quality. At the same time, it can also be used to heat heat media such as steam and heating oil to provide the necessary heat energy for subsequent reactions or quality control.
[0004] When a heat exchanger is in use, it is used for the heat transfer of petrochemical hot fluids. The heat is adjusted through the heat exchanger to quickly cool the heated materials to control the reaction rate and product quality and prevent the temperature from being too high. When the liquid enters the heat exchanger body, it needs to be filtered through a filter plate to reduce solid particles in the liquid and reduce blockage and damage to the pipeline. The filter plate needs to be replaced regularly. When replacing the filter plate of the existing device, it is necessary to first unscrew multiple bolts on the heat exchanger and then remove the bolts on the filter plate for replacement, which is relatively inconvenient. This will easily increase the replacement time, reduce the maintenance efficiency, and is not conducive to the operation of the heat exchanger. Summary of the Utility Model

This will easily increase the replacement time, reduce the maintenance efficiency, and is not conducive to the operation of the heat exchanger. This application provides a flash bottom oil and the second normal heat exchanger in the middle distillate fraction.
[0006] To achieve the above purpose, this application specifically adopts the following technical solutions:

[0011] Furthermore, the limiting component includes a limiting column slidably arranged within the fixing box. A first spring is fixed at the lower end of the limiting column. The lower end of the first spring is fixedly connected to the fixing box. The limiting column extends into the fixing hole. A handle is fixed on the limiting column.

[0012] By adopting the above technical solution, the movement of the handle drives the movement of the limiting column, causing the first spring to expand and contract, so that the limiting column is removed from the fixing hole, releasing the limitation on the arc-shaped plate.
[0013] Furthermore, the number of filter plates is three. The filter holes of the filter plates are arranged in decreasing order. The filter plates correspond to the arc-shaped plates. One side of the lower end of the arc-shaped plate and the end of the limiting column are both arc-shaped.

[0015] Furthermore, two symmetrical triangular blocks are fixed on the placing plate. Dampers are fixed on the triangular blocks. Three shock-absorbing plates are fixed at the lower end of the heat exchanger body. The telescopic end of the damper is in contact with one of the shock-absorbing plates. Two of the shock-absorbing plates are fixedly connected to the support plate.

[0023] In summary, the present application includes at least one of the following beneficial effects:
[0024] 1. When the heat exchanger is in use and needs to be replaced and maintained, the staff pulls the handle, and the movement of the handle drives the movement of the limiting column, so that the spring expands and contracts, and the limiting column moves out of the fixing hole, releasing the restriction on the arc plate, so that the arc plate moves out of the fixing groove, and resets after the replacement is completed, so that the staff can replace the filter plate. The three filter plates need to be replaced by pulling the corresponding handle. During replacement, the arc-shaped end of the arc plate contacts the arc-shaped end of the limiting column, so that the limiting column moves, and the limiting column enters the fixing hole to complete the replacement. The limiting mechanism is used to facilitate the replacement and cleaning of the filter plate, reduce the replacement time, increase the maintenance efficiency, and facilitate the operation of the heat exchanger.
[0025] 2. When the heat exchanger is in use, three shock-absorbing plates are used to reduce the shock of the heat exchanger body. The shock-absorbing plates are shock-absorbing rubber plates, which are convenient for increasing the shock-absorbing effect and reducing the vibration caused by the temperature change of the fluid flow. At the same time, through the expansion and contraction of the damper, the fixed plate 1 and the fixed plate 2 are driven to move, and the spring 2 is driven to expand and contract, so as to absorb and reduce the vibration, reduce the pressure at the connection between the support plate and the heat exchanger body, facilitate the stable operation of the heat exchanger body, and extend the service life.

Detailed implementation manners
[0032] The following further elaborates on this application in conjunction with the attached Figures 1-4 drawings.
[0033] The embodiment of this application discloses a flash bottom oil and normal second fraction heat exchanger.
[0034] Referring to Figure 1 and Figure 2 The flash bottom oil and normal second fraction heat exchanger includes a heat exchanger body 1. An inlet pipe 3 is fixed at one end of the heat exchanger body 1. An outlet pipe 4 is fixed on one side below the heat exchanger body 1. Two symmetric support plates 2 are arranged at the lower end of the heat exchanger body 1. A placing plate 5 is fixedly connected to the lower end of the support plate 2. A fixed box 6 is fixed at the upper end of the inlet pipe 3. A filter plate 8 is arranged in the fixed box 6. A limiting mechanism is arranged between the filter plate 8 and the fixed box 6.
[0035] When the heat exchanger is in use, the staff discharges the fluid for petrochemical use into the heat exchanger body 1 through the inlet pipe 3. After being adjusted by the heat exchanger body 1, it is discharged from the outlet pipe 4 and enters the next process. The heat exchanger body 1 is supported and fixed by the support plate 2. The fixed particulate matter in the fluid is filtered by the filter plate 8, reducing the entry of solid particulate matter into the heat exchanger body 1 and reducing the situations of blockage and damage. The limiting mechanism facilitates the replacement and cleaning of the filter plate 8, reducing the replacement time and increasing the maintenance efficiency, which is conducive to the operation of the heat exchanger.
[0036] Referring to Figures 2-4, the limiting mechanism includes an arc-shaped plate 9 fixed to one side of the filter plate 8. A fixing groove is provided in the arc-shaped plate 9 corresponding to the position of the fixing box 6. The arc-shaped plate 9 is located in the fixing groove. Fixing holes 20 are provided on both sides of the lower end of the arc-shaped plate 9. Cushion blocks 13 are fixed to both the upper and lower ends of the arc-shaped plate 9. The cushion blocks 13 are flexible rubber pads. A limiting component is provided between the arc-shaped plate 9 and the filter plate 8. The limiting component includes a limiting column 10 slidably arranged in the fixing box 6. A first spring 11 is fixed to the lower end of the limiting column 10. The lower end of the first spring 11 is fixedly connected to the fixing box 6. The limiting column 10 extends into the fixing hole 20. A handle 12 is fixed to the limiting column 10. The handle 12 slidably penetrates the fixing box 6. A connecting pipe 7 is fixedly connected to the fixing box 6. The number of filter plates 8 is three. The filter holes of the filter plates 8 are arranged from large to small in sequence. The filter plates 8 correspond to the arc-shaped plate 9. One side of the lower end of the arc-shaped plate 9 and the end of the limiting column 10 are both arc-shaped.
[0037] When the heat exchanger is in use, the three filter plates 8 filter the fluid. The filter holes of the three filter plates 8 are of different sizes. The solid particles in the fluid are filtered in sequence from large to small, and are filtered in stages, improving the cleanliness and purity of the fluid, improving the filtering effect, and facilitating the use of the filter plates 8. When replacement and maintenance are required, the staff pulls the handle 12. The movement of the handle 12 drives the movement of the limiting column 10, causing the first spring 11 to expand and contract, and causing the limiting column 10 to move out of the fixing hole 20, releasing the restriction on the arc-shaped plate 9, so that the arc-shaped plate 9 moves out of the fixing groove. After replacement, it is reset, facilitating the staff to replace the filter plates 8. To replace any of the three filter plates 8, just pull the corresponding handle 12. When replacing, the arc-shaped end of the arc-shaped plate 9 abuts against the arc-shaped end of the limiting column 10, causing the limiting column 10 to move, and the limiting column 10 enters the fixing hole 20 to complete the replacement. The cushion blocks 13 improve the sealing effect between the arc-shaped plate 9 and the fixing box 6. Through the limiting mechanism, it is convenient to replace and clean the filter plates 8, reducing the replacement time, increasing the maintenance efficiency, and facilitating the operation of the heat exchanger.
[0038] Refer to Figure 2 and Figure 3 , two symmetrical triangular blocks 15 are fixed on the placing plate 5. Dampers 16 are fixed on the triangular blocks 15. Three shock-absorbing plates 14 are fixed to the lower end of the heat exchanger body 1. The telescopic end of the damper 16 is in contact with one of the shock-absorbing plates 14. Two of the shock-absorbing plates 14 are fixedly connected to the support plate 2. A fixing plate one 17 is fixed on the damper 16. A fixing plate two 19 is fixed to the telescopic end of the damper 16. A second spring 18 is sleeved on the damper 16. The ends of the second spring 18 are fixedly connected to the fixing plate one 17 and the fixing plate two 19 respectively. The shock-absorbing plates 14 are shock-absorbing rubber plates. An anti-corrosion layer is provided on the surface of the heat exchanger body 1. The anti-corrosion layer is an epoxy resin anti-corrosion layer.
[0039] When the heat exchanger is in use, three shock-absorbing plates 14 shock-absorb the heat exchanger body 1. The shock-absorbing plates 14 are shock-absorbing rubber plates, which are convenient for increasing the shock-absorbing effect and reducing the vibration generated by the change in the fluid flow temperature. At the same time, through the expansion and contraction of the damper 16, the vibration is reduced, and then the fixing plate one 17 and the fixing plate two 19 are driven to move, driving the spring two 18 to expand and contract, which is convenient for absorbing and reducing the vibration, reducing the pressure at the connection between the support plate 2 and the heat exchanger body 1, facilitating the stable operation of the heat exchanger body 1, extending the service life, and the anti-corrosion layer is an epoxy resin layer, which increases the anti-corrosion effect on the surface of the heat exchanger body 1 and is convenient for use.
[0040] The implementation principle of the flash bottom oil and normal second fraction heat exchanger in this embodiment is as follows: When the heat exchanger is in use, the staff discharges the fluid for petrochemical use into the heat exchanger body 1 through the inlet pipe 3. After being adjusted by the heat exchanger body 1, it is discharged from the outlet pipe 4 and enters the next process. The heat exchanger body 1 is supported and fixed by the support plate 2, and the fixed particulate matter in the fluid is filtered by the filter plate 8, reducing the entry of solid particulate matter into the heat exchanger body 1 and reducing the situation of blockage and damage.
[0041] When the heat exchanger is in use, three filter plates 8 filter the fluid. The filter holes of the three filter plates 8 are of different sizes, and the solid particles in the fluid are filtered sequentially from large to small, for hierarchical filtration, improving the cleanliness and purity of the fluid, enhancing the filtration effect, and facilitating the use of the filter plate 8. When replacement and maintenance are required, the staff pulls the handle 12. The movement of the handle 12 drives the limiting column 10 to move, causing the spring one 11 to expand and contract, so that the limiting column 10 moves out of the fixing hole 20, releasing the restriction on the arc plate 9, enabling the arc plate 9 to move out of the fixing groove. After replacement, it is reset, which is convenient for the staff to replace the filter plate 8. To replace any of the three filter plates 8, just pull the corresponding handle 12. During replacement, the arc end of the arc plate 9 abuts against the arc end of the limiting column 10, causing the limiting column 10 to move. The limiting column 10 enters the fixing hole 20 to complete the replacement. The cushion block 13 increases the sealing effect between the arc plate 9 and the fixing box 6.
[0042] When the heat exchanger is in use, three shock-absorbing plates 14 shock-absorb the heat exchanger body 1. The shock-absorbing plates 14 are shock-absorbing rubber plates, which are convenient for increasing the shock-absorbing effect and reducing the vibration generated by the change in the fluid flow temperature. At the same time, through the expansion and contraction of the damper 16, the fixing plate one 17 and the fixing plate two 19 are driven to move, driving the spring two 18 to expand and contract, which is convenient for absorbing and reducing the vibration, reducing the pressure at the connection between the support plate 2 and the heat exchanger body 1, facilitating the stable operation of the heat exchanger body 1, extending the service life, and the anti-corrosion layer is an epoxy resin layer, which increases the anti-corrosion effect on the surface of the heat exchanger body 1 and is convenient for use.
