Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a corrosion-resistant inner lining structure for a polyaluminum chloride reaction vessel. Background Technology

[0002] A corrosion-resistant reactor is disclosed in Chinese Publication No. CN104275135A. Most existing reactors use acid-resistant enamel as their lining; however, the enamel surface is prone to cracking, causing inconvenience for installation, use, and maintenance. Furthermore, the fully enclosed structure of the reactor makes maintenance difficult for personnel. This improved corrosion-resistant reactor includes a reactor body with a methylphenyl vinyl silicone rubber layer on its inner wall and an external inspection door made of transparent polyethylene. The improved reactor solves the problem of enamel cracking, enhances the corrosion resistance of the reactor lining, extends the equipment's service life, and facilitates maintenance and repair.

[0003] The aforementioned and existing technologies use an adhesive-bonded anti-corrosion lining structure inside the reactor, which is difficult to change once the lining material is selected and installed. To adapt to new reaction conditions or in case of localized damage, the entire anti-corrosion lining inside the reactor may need to be removed and replaced, resulting in high costs, complex operations, and an inability to quickly replace the anti-corrosion lining. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that make it impossible to quickly replace the anti-corrosion lining inside a reaction vessel, and to propose an anti-corrosion lining structure for a polyaluminum chloride reaction vessel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a corrosion-resistant lining structure for a polyaluminum chloride reactor, comprising a reactor body, a reactor cover at the top of the reactor body, a pressing edge inside the reactor cover, two limiting frames inside the reactor body, a vertical plate on one side of each of the two limiting frames, a bottom plate at the bottom of each of the two vertical plates, an inner lining plate on the surface of each of the two limiting frames, a fixing frame at the top of each of the two vertical plates, a first sealing strip on both sides of each of the two limiting frames, and a second sealing strip surrounding the outside of the bottom plate.

[0006] Preferably, the vessel cover is installed on the top of the reactor body, and the flange connecting the vessel cover and the reactor body is provided on the inner wall surface of the vessel cover, and the flange is integrally formed with the vessel cover.

[0007] Preferably, the two limiting frames are evenly arranged on the surface of the inner wall of the reactor body, and the limiting frames are integrally formed with the reactor body. The two limiting frames are evenly arranged on both sides inside the reactor body, and both limiting frames are T-shaped.

[0008] Preferably, the fixing frame is installed on the top surface of the limiting frame, and the fixing frame is bolted to the limiting frame, and the inner lining plates are all glued to the vertical plate and the bottom plate.

[0009] Preferably, the two vertical plates are mirror images of each other with the two limiting frames as the center, and both ends of the two vertical plates are installed in the limiting frames.

[0010] Preferably, the bottom plate is installed on the bottom surface inside the reactor body, and both limiting frames extend through the bottom plate.

[0011] Preferably, the four first sealing strips are evenly embedded and glued to both sides of the two limiting frames, and the second sealing strips are evenly embedded and installed on the bottom surface inside the reactor body.

[0012] Beneficial effects

[0013] In this invention, the lining plate is pre-attached to two vertical plates and a bottom plate. When replacing, simply remove the screws on the fixing bracket, pull out the old vertical and bottom plates, and install the newly fitted bottom and vertical plates with the lining plate inside the reactor. The bottom plate is installed at the bottom of the two vertical plates and is fixed inside the reactor by the vertical plates. After installation, the fixing bracket is fixed to the top of the two vertical plates and the limiting bracket and secured with two fixing bolts, thus fixing the vertical plates inside the reactor to complete the replacement. The entire replacement process only requires pulling out the old vertical and bottom plates and inserting the new bottom and vertical plates into the two limiting brackets. There is no need to remove the entire lining structure inside the reactor, solving the problem of not being able to quickly replace the anti-corrosion lining inside the reactor.

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0025] Reference Figure 1-4 A corrosion-resistant lining structure for a polyaluminum chloride reactor includes a reactor body 1, a reactor cover 2 on top of the reactor body 1, a pressing edge 3 inside the reactor cover 2, two limiting frames 4 inside the reactor body 1, a vertical plate 7 on one side of each of the two limiting frames 4, a bottom plate 6 at the bottom of each of the two vertical plates 7, an inner lining plate 8 on the surface of each of the two limiting frames 4, a fixing frame 5 on the top of each of the two vertical plates 7, a first sealing strip 9 on both sides of each of the two limiting frames 4, and a second sealing strip 10 surrounding the outside of the bottom plate 6. The reactor cover 2 is installed on top of the reactor body 1, and the flange connection pressing edge 3 between the reactor cover 2 and the reactor body 1 is set on the inner wall surface of the reactor cover 2, and the pressing edge 3 is integrally formed with the reactor cover 2. The limiting frames 4 are evenly arranged on the inner wall surface of the reactor body 1, and the limiting frames 4 are integrally formed with the reactor body 1. Two limiting frames 4 are evenly arranged on both sides inside the reactor body 1. Both limiting frames 4 are T-shaped. The fixing frame 5 is installed on the top surface of the limiting frame 4, and the fixing frame 5 is bolted to the limiting frame 4. The inner lining plate 8 is glued to the vertical plate 7 and the bottom plate 6. The two vertical plates 7 are mirror images of the two limiting frames 4, and both ends of the two vertical plates 7 are installed in the limiting frames 4. The bottom plate 6 is installed on the bottom surface inside the reactor body 1, and both limiting frames 4 penetrate through the bottom plate 6. Four first sealing strips 9 are evenly embedded and glued on both sides of the two limiting frames 4. The second sealing strip 10 is embedded on the bottom surface inside the reactor body 1.

[0026] The vessel cover 2 is installed on the reactor body 1 and connected to the flange of the reactor body 1. The vessel cover 2 seals the internal space of the reactor body 1. The pressure edge 3 is set on the inner wall surface of the vessel cover 2 and is integrally formed with the vessel cover 2. The pressure edge 3 is set directly above the fixing frame 5. When the vessel cover 2 is installed on the reactor body 1, the pressure edge 3 will press against the fixing frame 5. The fixing frame 5 is installed on the top surface of the limiting frame 4 by two fixing bolts. The fixing frame 5 fixes the vertical plate 7 inserted into the limiting frame 4. The vertical plate 7 is fixed by the double pressing and fixing of the fixing frame 5 and the pressure edge 3. Both limiting frames 4 are The limiting frames 4 are evenly arranged on the inner wall surface of the reactor body 1, and are integrally formed with the reactor body 1. Two limiting frames 4 are evenly arranged on both sides inside the reactor body 1. Both limiting frames 4 are T-shaped, with the protruding parts on both sides of the T-shaped limiting frame 4 used to install the vertical plate 7. The bottom plate 6 is on the bottom surface of the vertical plate 7. When the vertical plate 7 is pressed and fixed by the fixing frame 5 and the pressing edge 3, the vertical plate 7 will also press and fix the bottom plate 6. The inner lining plate 8 is glued to both the vertical plate 7 and the bottom plate 6. It should be noted that the inner lining plate 8 can also be glued to the two limiting frames 4 by cutting the inner lining plate 8 to the same size as the limiting frame 4. The desired shape is acceptable, but the inner lining plate 8 adhered to the limiting frame 4 needs to be manually removed and cannot be quickly replaced. The two vertical plates 7 and the bottom plate 6 are replacement parts. During installation, the bottom plate 6 must first be installed on the lowest surface inside the reactor body 1. Only after the bottom plate 6 is installed can the two vertical plates 7 be installed. When installing the vertical plates 7, the vertical plates 7 are attached to the inner wall of the reactor body 1, and the two ends of the vertical plates 7 are inserted into the two T-shaped limiting frames 4 on the inner wall of the reactor body 1. However, when installing the bottom plate 6 and the vertical plates 7, the second sealing strip 10 must first be inlaid on the bottom surface inside the reactor body 1. The four first sealing strips 9 are evenly embedded in the raised parts on both sides of the two limiting frames 4 at the junction of the inner wall of the reactor body 1 and the ground. The connection between the bottom plate 6 and the two vertical plates 7 and the two limiting frames 4 is sealed by the second sealing strip 10. The four first sealing strips 9 seal the connection between the two ends of the two vertical plates 7 and the two limiting frames 4, preventing the chemical solution from leaking through the connection between the vertical plates 7 and the two limiting frames 4 or the connection between the bottom plate 6 and the two limiting frames 4 and the two vertical plates 7 during use, thereby preventing corrosion inside the reactor body 1.

[0027] During the installation of the inner liner plate 8, first ensure that the inside of the reactor body 1 is clean, dry, and free of debris. Prepare the components to be replaced, such as the bottom plate 6, vertical plate 7, inner liner plate 8, first sealing strip 9, and second sealing strip 10. Attach the inner liner plate 8 to the vertical plate 7 and the bottom plate 6. Install the second sealing strip 10 mirror-image on the bottom surface inside the reactor body 1, centered on the two limiting brackets 4. The embedding position is at the junction of the inner wall and the bottom surface of the reactor body 1. At the same time, evenly embed the four first sealing strips 9 on the protruding parts on both sides of the two limiting brackets 4. Place the bottom plate 6 on the lowest surface inside the reactor body 1, ensuring that the bottom plate 6 fits tightly with the installed second sealing strip 10 to prepare for subsequent sealing. When installing the vertical plate 7, pick up the vertical plate 7 and attach it to the inner wall of the reactor body 1. Then carefully insert the two ends of the vertical plate 7 into the protruding parts on both sides of the two T-shaped limiting brackets 4 on the inner wall of the reactor body 1. During this process, care must be taken not to damage the already installed first sealing strip 9 on the vertical plate 7, and it must be ensured that the vertical plate 7 and the limiting frame 4 are tightly fitted so that the vertical plate 7 can be stably placed on the limiting frame 4. The fixing frame 5 is installed on the top surface of the limiting frame 4 using two fixing bolts, so that the fixing frame 5 is above the vertical plate 7. When the vessel cover 2 is installed on the reactor body 1, the integrally formed pressing edge 3 on the inner wall of the vessel cover 2 will press down on the fixing frame 5. The vertical plate 7 is fixed in place by the double pressing action of the fixing frame 5 and the pressing edge 3, and the vertical plate 7 in turn presses down and fixes the bottom plate 6. After installation, carefully check whether the connections between each component are tight and whether there are any gaps at the seals to ensure good sealing inside the reactor body 1 and prevent chemical solution leakage. Specific Implementation Example 2:

[0029] Reference Figure 1-6 A corrosion-resistant inner lining structure for a polyaluminum chloride reactor is further based on the basic structure in Specific Embodiment 1. The two limiting frames 4 can be changed from being integrally formed to being fixedly connected by fixing bolts. In this way, when the limiting frame 4 is damaged, the fixing bolts on the limiting frame 4 can be removed, and the new limiting frame 4 can be fixed to the inner wall of the reactor body 1 by fixing bolts. Compared with the integrally formed limiting frame 4, the limiting frame 4 fixed by fixing bolts is easier to replace and maintain in the future.

[0030] In summary:

[0031] 1. The inner lining plate 8 is pre-bonded to the two vertical plates 7 and the bottom plate 6. When replacing, simply remove the screws on the fixing bracket 5, pull out the old vertical plates 7 and the bottom plate 6, and install the newly installed bottom plate 6 and vertical plates 7 with the inner lining plate 8 inside the reactor in sequence. The bottom plate 6 is installed at the bottom of the two vertical plates 7 and is fixed inside the reactor by the vertical plates 7. After installation, the fixing bracket 5 is fixedly installed on the top of the two vertical plates 7 and the limiting bracket 4 and fixed with two fixing bolts, thereby fixing the vertical plates 7 inside the reactor to complete the replacement. The entire replacement process only requires pulling out the old vertical plates 7 and the bottom plate 6 and inserting the new bottom plate 6 and the vertical plates 7 into the two limiting brackets 4. There is no need to remove the entire inner lining structure inside the reactor, which solves the disadvantage of not being able to quickly replace the anti-corrosion lining inside the reactor.
