Description

Technical Field

[0001] This utility model relates to the field of reboiler technology, specifically to a corrosion-resistant reboiler. Background Technology

[0002] Reboilers are often used in conjunction with fractionating columns: a reboiler is a special heat exchanger that can exchange heat and has a vaporization space. The liquid level in the reboiler is at the same height as the liquid level in the fractionating column. Liquid phase is supplied from the bottom of the column into the reboiler. Typically, 25-30% of the liquid phase is vaporized in the reboiler. The vaporized two-phase flow is sent back to the fractionating column; the vapor phase component rises through the trays, while the liquid phase component falls back to the bottom.

[0003] Application number CN202121289191.X discloses a corrosion-resistant reboiler device, including a bottom sealing mechanism, a bend, and a tube side, as well as a heat exchange mechanism, a buffer mechanism, and a dispersion mechanism. This invention can improve the corrosion resistance of the dispersion tube and the bend, extend their service life, prevent perforation, and improve production safety. However, in practical use, the dispersion mechanism reduces the impact force of the airflow, which exposes the dispersion mechanism to corrosion and damage. With prolonged use, the dispersion mechanism needs to be replaced, which is inconvenient and often involves replacing the entire device, increasing the operating cost of the reboiler. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A corrosion-resistant reboiler includes a heat exchange mechanism and an anti-corrosion mechanism. The heat exchange mechanism includes a reboiler body, a lower flange sleeved on the top of the reboiler body, an exhaust channel fitted to the top of the lower flange, and an upper flange sleeved on the outside of the exhaust channel and connected to the lower flange by bolts. The anti-corrosion mechanism includes multiple metal middle plates fitted to the inner wall of the exhaust channel, two metal side plates installed on both sides of the metal middle plates, a slot formed between the metal middle plates and the metal side plates, multiple insert rods installed on the outside of the metal middle plates and inserted into the inner wall of the exhaust channel, and magnets embedded on the outside of the metal side plates, wherein the magnets are magnetically attracted to the inner wall of the exhaust channel.

[0007] By adopting the above technical solution, when the metal middle plate and metal side plate on one side are severely damaged, the two insert rods at the top of that side are rotated, and then the metal side plate rotates towards the center of the metal middle plate. The magnet separates from the inner wall of the exhaust channel, and then the insert rod on the metal middle plate separates from the exhaust channel. This allows the metal middle plate and metal side plate on that side to be replaced, effectively avoiding the need for complete replacement and reducing the operating cost of the reboiler.

[0008] In a preferred embodiment, the present invention can be further configured such that: the bolts are multiple, and the multiple bolts are equally spaced and arranged in a ring.

[0009] In a preferred embodiment, the present invention can be further configured such that: multiple metal middle plates are arranged in a rectangular pattern, and the metal middle plates and metal side plates are all made of metal materials.

[0010] In a preferred embodiment, the present invention can be further configured such that: multiple inserts on the outer side of the metal middle plate are equally spaced and arranged in a matrix, and the length of the metal middle plate is less than the wall thickness of the exhaust channel.

[0011] In a preferred embodiment, the present invention can be further configured such that a pull rod is installed on the top of the metal side plate, and the pull rod is T-shaped.

[0012] In a preferred embodiment, the present invention can be further configured such that the top end of the pull rod is circumferentially covered with multiple grooves.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, when the metal middle plate and metal side plate on one side are severely damaged, the two insert rods at the top of that side are rotated, and then the metal side plate rotates towards the center of the metal middle plate. The magnet separates from the inner wall of the exhaust channel, and then the insert rod on the metal middle plate separates from the exhaust channel. This allows the metal middle plate and metal side plate on that side to be replaced, effectively avoiding the need for complete replacement and reducing the cost of using the reboiler.

[0015] 2. In this utility model, when the mixed gas generated inside the reboiler body passes through the exhaust channel, the impact force of the mixed gas directly acts on multiple metal middle plates and metal side plates, effectively preventing damage to the inner wall of the exhaust channel and extending the service life of the exhaust channel.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0026] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a corrosion-resistant reboiler.

[0027] Example 1:

[0028] Combination Figure 1-4 As shown, the present invention provides a corrosion-resistant reboiler, including a heat exchange mechanism 100 and an anti-corrosion mechanism 200. The heat exchange mechanism 100 includes a reboiler body 110, a lower flange 120 sleeved on the top of the reboiler body 110, an exhaust channel 130 fitted to the top of the lower flange 120, and an upper flange 140 sleeved on the outside of the exhaust channel 130 and connected to the lower flange 120 by bolts 150.

[0029] The anti-corrosion mechanism 200 includes a plurality of metal middle plates 210 that are attached to the inner wall of the exhaust channel 130, two metal side plates 220 installed on both sides of the metal middle plates 210, a slot 230 formed between the metal middle plates 210 and the metal side plates 220, a plurality of insert rods 240 installed on the outer side of the metal middle plates 210 and inserted into the inner wall of the exhaust channel 130, and a magnet 250 embedded on the outer side of the metal side plates 220, wherein the magnet 250 is magnetically attracted to the inner wall of the exhaust channel 130.

[0030] Furthermore, the bolts 150 are provided in multiples, and the multiple bolts 150 are equally spaced and arranged in a ring. The layout design of the multiple bolts 150 can improve the connection between the exhaust channel 130 and the reboiler body 110.

[0031] Furthermore, multiple metal middle plates 210 are arranged in a rectangular shape. The metal middle plates 210 and metal side plates 220 are both made of metal materials. The metal middle plates 210 and metal side plates 220 made of metal materials have strong resistance to the impact of mixed gases, avoiding frequent replacement of metal middle plates 210 / metal side plates 220 and improving the comfort of using this device.

[0032] Furthermore, the multiple inserts 240 on the outer side of the metal middle plate 210 are equally spaced and arranged in a matrix. The length of the metal middle plate 210 is less than the wall thickness of the exhaust channel 130. The layout design of the inserts 240 enables the metal middle plate 210 and the exhaust channel 130 to be firmly connected.

[0033] Example 2:

[0034] Combination Figure 1 , 3 and Figure 4 As shown, based on Embodiment 1, a pull rod 300 is installed on the top of the metal side plate 220. The pull rod 300 is T-shaped. The pull rod 300 facilitates the rotation of the metal side plate 220, making it easy to remove the metal middle plate 210 from the exhaust channel 130.

[0035] Example 3:

[0036] Combination Figure 1 , 3 and Figure 4 As shown in the above embodiment, the top end of the pull rod 300 is provided with multiple grooves, which facilitates the user to rotate the pull rod 300 and improves the ease of rotation of the pull rod 300.

[0037] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the mixed gas generated in the reboiler body 110 passes through the exhaust channel 130. The impact force of the mixed gas directly acts on multiple metal middle plates 210 and metal side plates 220, effectively preventing damage to the inner wall of the exhaust channel 130 and extending the service life of the exhaust channel 130. Then, when the metal middle plate 210 and metal side plate 220 on a single side are severely damaged, the two insert rods 240 at the top of that side are rotated. Then, the metal side plate 220 rotates towards the center of the metal middle plate 210, and the magnet 250 separates from the inner wall of the exhaust channel 130. Then, the insert rods 240 on the metal middle plate 210 are separated from the exhaust channel 130. This allows the metal middle plate 210 and metal side plate 220 on that side to be replaced, effectively avoiding the need for complete replacement and reducing the cost of using the reboiler.

[0038] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
