Description

Technical Field

[0001] This utility model relates to the field of reheater technology, and in particular to a reheater for chemical product processing. Background Technology

[0002] A reheater is a device used to heat fluids, typically in industrial processes such as chemical, petroleum, and natural gas industries. The reheater works by transferring heat from one fluid (such as hot water or steam) to another fluid that needs heating (such as natural gas or other chemical feedstock), thereby heating the latter.

[0003] In existing technologies, long and thin heat pipes are usually designed to help transfer heat faster. However, when using steam for heating, the steam turns into liquid after releasing heat and adheres to the surface of the heat pipe. The liquid absorbs the heat from the steam and carries away the heat after dripping, affecting the overall heating efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a reheater for chemical product processing, which can collect the liquid converted from steam and reuse the heat therein, thereby improving the overall heating efficiency.

[0005] This utility model provides a reheater for chemical product processing, comprising:

[0008] A liquid collection tank is located inside the shell. The bottom of the liquid collection tank is provided with a drain hole. The liquid collection tank is sleeved on the heat-conducting pipe through the drain hole, and a gap is left between the wall of the drain hole and the outer wall of the heat-conducting pipe.

[0009] A spring support rod is fixedly connected to the bottom surface of the liquid collection tank, and the spring support rod supports the liquid collection tank upward to abut against the stop block;

[0010] Steam contacts the heat-conducting pipe to form condensate, which drips into the collection tank. After the condensate accumulates, it presses down into the collection tank and is discharged through the drain hole.

[0011] Preferably, the reheater for processing chemical products further includes a recovery tank located below the liquid collection tank. The recovery tank is a flat sheet metal part, and the outer edge of the recovery tank is fixedly connected to the inner wall of the shell. An isolation protrusion is integrally formed on the recovery tank, and a socket hole is opened at the center of the top of the isolation protrusion. The wall of the socket hole is attached to the outer wall of the heat conduction pipe.

[0012] Preferably, the lower edge of the stop block and the upper edge of the drain hole in the collection tank are both chamfered, and the spring support rod supports the chamfered surface of the collection tank to abut against the chamfered surface of the stop block.

[0013] Preferably, the housing is integrally formed with an air inlet and an air outlet, the air inlet facing upwards near the upper end of the heat pipe, and the air outlet facing downwards near the lower end of the heat pipe.

[0014] Preferably, the vertical height of the highest point of the air outlet is lower than the vertical height of the lowest point of the liquid collection tank.

[0015] Preferably, the reheater for processing chemical products further includes two distributors, each of which is connected in series through the heat pipe. The upper and lower ends of the shell are respectively fixedly connected to the two distributors.

[0032] Combination Figures 1 to 5 As shown, the reheater for chemical product processing provided by this utility model includes a heat-conducting pipe 1, a shell 2, a liquid collection tank 3, and a spring support rod 4.

[0033] Combination Figures 1 to 5 As shown, the heat pipe 1 is placed vertically and contains chemical raw materials. A baffle 11 is integrally formed on the outer wall of the heat pipe 1. The shell 2 covers the heat pipe 1 and contains steam. The liquid collection tank 3 is located inside the shell 2. The bottom of the liquid collection tank 3 is provided with a drain hole. The liquid collection tank 3 is sleeved on the heat pipe 1 through the drain hole, and a gap is left between the drain hole wall and the outer wall of the heat pipe 1. The spring support rod 4 is fixedly connected to the bottom surface of the liquid collection tank 3. The spring support rod 4 supports the liquid collection tank 3 upward to abut against the baffle 11. Steam contacts the heat pipe 1 to form condensate and drips into the liquid collection tank 3. After the condensate accumulates, it presses down on the liquid collection tank 3 and is discharged from the liquid collection tank 3 through the drain hole.

[0034] In this embodiment, by mounting the liquid collection tank 3 on the vertically placed heat-conducting pipe 1, the liquid converted from the heat released by the steam automatically slides into the liquid collection tank 3, completing the collection of the liquid. At the same time, the liquid in the liquid collection tank 3 will contact the wall of the heat-conducting pipe 1, and the liquid will continue to be heated through the liquid collection tank 3, improving the overall heating efficiency. Meanwhile, through the cooperation of the baffle 11 and the spring support rod 4, the liquid in the liquid collection tank 3 will automatically discharge the part of the liquid with a lower internal temperature after it accumulates to a certain amount, so as to achieve high-efficiency heating while ensuring internal circulation.

[0035] In some embodiments, combined with Figure 2 , Figure 3 As shown, the reheater for chemical product processing also includes a recovery tank 5, which is located below the liquid collection tank 3. The recovery tank 5 is a flat sheet metal part, and its outer edge is fixedly connected to the inner wall of the shell 2. An isolation protrusion is integrally formed on the recovery tank 5, and a socket hole is opened at the top center of the isolation protrusion. The wall of the socket hole fits against the outer wall of the heat conduction pipe 1. The recovery tank 5 can collect the liquid discharged from the liquid collection tank 3, and then the isolation protrusion above isolates the liquid from the heat conduction pipe 1 to prevent the liquid from absorbing the heat of the heat conduction pipe 1 and affecting the heating effect.

[0036] In some embodiments, combined with Figure 1 , Figure 2 As shown, the lower edge of the baffle 11 and the upper edge of the drain hole in the collection tank 3 are both chamfered. The spring support rod 4 supports the chamfered surface of the collection tank 3 to abut against the chamfered surface of the baffle 11. The chamfer design changes the contact surface between the baffle 11 and the collection tank 3 from a plane to a curved surface, making the sealing effect more stable and also increasing the positioning function, effectively improving the reliability of equipment operation.

[0037] In some embodiments, combined with Figure 2 As shown, the housing 2 is integrally formed with an air inlet 21 and an air outlet 22. The air inlet 21 is upward and close to the upper end of the heat conduction pipe 1, and the air outlet 22 is downward and close to the lower end of the heat conduction pipe 1. The two channels, air inlet 21 and air outlet 22, can ensure that the steam diffuses more fully in the housing 2. At the same time, the characteristic of thermal expansion and contraction is used to ensure that the gas passing through the air outlet 22 is the lower temperature part of the steam, thereby improving the heat utilization rate.

[0038] In some embodiments, combined with Figure 2 As shown, the vertical height of the highest point of the air outlet 22 is lower than the vertical height of the lowest point of the liquid collection tank 3, thereby ensuring that the liquid discharged from the liquid collection tank 3 can be recovered through the air outlet 22.

[0039] In some embodiments, combined with Figure 2As shown, the reheater for chemical product processing also includes a distributor 12. There are two distributors 12, and each of the two distributors 12 is connected in series through the heat pipe 1. The upper and lower ends of the shell 2 are respectively fixedly connected to the two distributors 12. The distributors 12 can effectively increase the contact area, accelerate the heat transfer, and improve the heating efficiency.

[0040] In some embodiments, combined with Figure 2 , Figure 3 As shown, the number of water holes at the bottom of the liquid collection tank 3 is the same as the number of heat conduction pipes 1. The liquid collection tank 3 is simultaneously fitted onto all the heat conduction pipes 1. This design can effectively simplify the internal structure. At the same time, the shared liquid collection tank 3 can improve the uniformity of the heating effect of each heat conduction pipe 1. Due to the position of the air inlet 21, the effect of each heat conduction pipe 1 in contact with steam is different. By sharing the liquid collection tank 3, heat transfer between different heat conduction pipes 1 can be realized.

[0041] In some embodiments, combined with Figure 1 As shown, the number of liquid collection tanks 3 is the same as the number of heat conduction pipes 1. Each heat conduction pipe 1 is fitted with a liquid collection tank 3. The structure of the liquid collection tank 3 is simpler and conducive to standardized production.

[0042] In some embodiments, combined with Figure 2 , Figure 3 As shown, the shell 2 is a double-layer plate with a hollow layer between the two layers. The double-layer shell 2 has better heat insulation, which can effectively reduce heat loss and improve heating efficiency.

[0043] In some embodiments, combined with Figure 5 As shown, the heat pipe 1 includes a bent section and a straight section. The baffle 11 is disposed on the straight section, and the liquid collection tank 3 is sleeved on the straight section. The bent section can effectively reduce the flow rate of the internal fluid, and at the same time, the bent section can provide a longer pipe length, thereby extending the heat transfer time and improving the heating effect.

[0044] Working process: Steam enters the interior of the shell 2 and contacts the outer wall of the heat pipe 1. After releasing heat, the steam turns into liquid and adheres to the heat pipe 1. Then, the liquid flows into the collection tank 3 along the vertically placed heat pipe 1. The liquid in the collection tank 3 contacts the outer wall of the heat pipe 1 and heats the heat pipe 1. Under the action of the spring support rod 4, the collection tank 3 blocks the drain hole on the block 11. When the liquid in the collection tank 3 accumulates to a certain amount, the increased gravity causes the collection tank 3 to press down the spring support rod 4. The block 11 and the collection tank 3 are separated. The liquid at the bottom of the collection tank 3 with a lower temperature is discharged through the drain hole of the collection tank 3 until the spring support rod 4 pushes the collection tank 3 against the block 11 again.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
