Description

Technical Field

[0001] This utility model relates to the field of crude benzene recovery, and in particular to a crude benzene recovery and dehydration device. Background Technology

[0002] Crude benzene recovery and dehydration equipment is commonly used in industries such as petrochemicals and coal chemicals. Its purpose is to remove moisture from crude benzene to improve its purity and meet subsequent production needs. The dehydration process is usually carried out through methods such as adsorption, distillation, or molecular sieves.

[0003] However, in order to ensure the crude benzene treatment effect, the existing molecular sieve dehydration equipment needs to be shut down every once in a while to regenerate the molecular sieve. The regeneration process takes a long time, which undoubtedly affects the crude benzene recovery efficiency and makes it difficult to achieve efficient crude benzene recovery.

[0004] Furthermore, molecular sieves often require replacement and maintenance after prolonged use. This necessitates removing the molecular sieve from the equipment, which is often fixedly installed in the dewatering equipment, making disassembly inconvenient and hindering the rapid installation and removal of molecular sieves.

[0005] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a crude benzene recovery and dehydration device to address the technical deficiencies mentioned in the background art.

[0007] The purpose of this utility model can be achieved through the following technical solution: a crude benzene recovery and dehydration device, including a tank body one, tank bodies two are arranged on both sides of the tank body one, and an adjustment component is movably installed inside the tank body one, the adjustment component including a moving frame, a filter plate and a locking block;

[0008] The movable frame is movably installed in the tank, the filter plate is fixedly installed in the movable frame, and the locking block is movably installed on the movable frame, with the locking block abutting against the surface of the filter plate;

[0009] An air inlet pipe is fixedly installed at the bottom of tank body two, and an exhaust pipe is fixedly installed at the top of tank body two. The filter plate is located between the air inlet pipe and the exhaust pipe. Both tank body one and tank body two are provided with movable slots, and the movable frame is movably installed in the movable slots.

[0010] Preferably, a connecting plate is fixedly installed on the tank body 2, a lead screw is movably installed between the connecting plates, a motor is fixedly installed on the connecting plate, and the output end of the motor is fixedly connected to the lead screw.

[0011] Preferably, a movable nut is movably installed on the lead screw via threads, and a limit plate is fixedly installed on the movable frame, with the limit plate and the movable nut being fixedly connected.

[0012] Preferably, there are two filter plates, which are located on both sides of the limiting plate.

[0013] Preferably, the movable frame has a sliding groove, and the locking block is movably installed in the sliding groove. The locking block has a T-shaped cross-section.

[0014] Preferably, multiple card blocks are provided, and the multiple card blocks are symmetrically arranged on the moving frame.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) This utility model uses the linkage of components such as tank one and tank two to first introduce crude benzene into tank one, filter it through the filter plate and then discharge it. The filter plate absorbs the water in the crude benzene, thereby dehydrating the crude benzene. After a period of use, the moving frame is moved so that the filter plate that needs to be regenerated is moved into tank two. At this time, another filter plate that has been regenerated is moved into tank one. The filter plate is regenerated through tank two. The above steps are repeated to achieve continuous dehydration of crude benzene and effectively improve the crude benzene treatment efficiency.

[0017] (2) By using the combination of the movable frame and the locking block, when the filter plate needs to be replaced or repaired, it is only necessary to move the tank body two on the side to be disassembled, push the locking block, and separate the locking block from the surface of the filter plate. At this time, the filter plate is in a free state, and the filter plate can be taken out from the movable frame by pulling the filter plate, which is very convenient. At the same time, the disassembly process does not affect the processing of crude benzene inside the tank body one, which is highly practical. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] This embodiment addresses the problem that in existing molecular sieve dehydration equipment, to ensure the effectiveness of crude benzene treatment, the equipment needs to be shut down periodically for regeneration of the molecular sieve. The regeneration process is time-consuming, which undoubtedly affects the crude benzene recovery efficiency and makes it difficult to achieve efficient crude benzene recovery.

[0028] Please see Figure 1 - Figure 3 As shown, this embodiment is a crude benzene recovery and dehydration device, including a tank body 1, with tank bodies 2 11 on both sides of the tank body 1. An adjustment component 2 is movably installed inside the tank body 1. The adjustment component 2 includes a movable frame 21, a filter plate 22 and a locking block 23. Pipes are fixedly installed at the top and bottom of the tank body 1, that is, crude benzene is transported to the tank body 1 through the pipes.

[0029] The movable frame 21 is movably installed in the tank 1, and the filter plate 22 is fixedly installed in the movable frame 21. The filter plate 22 is specifically a molecular sieve, which utilizes the selective adsorption effect of the molecular sieve to adsorb water without adsorbing benzene, thereby achieving the purpose of dehydration. It can dehydrate efficiently and continuously, and the equipment structure is relatively simple.

[0030] The locking block 23 is movably installed on the movable frame 21. The locking block 23 abuts against the surface of the filter plate 22. The movable frame 21 has a sliding groove 31. The locking block 23 is movably installed in the sliding groove 31. The cross-section of the locking block 23 is T-shaped. Multiple locking blocks 23 are provided and are symmetrically arranged on the movable frame 21.

[0031] When the filter plate 22 needs to be replaced or repaired, simply move the tank body 11 on the side to be disassembled, push the locking block 23 to separate the locking block 23 from the surface of the filter plate 22. At this time, the filter plate 22 is in a free state, and it can be removed from the moving frame 21 by pulling the filter plate 22. It is very convenient. At the same time, the disassembly process does not affect the processing of crude benzene inside the tank body 1, making it highly practical.

[0032] Example 2:

[0033] This embodiment addresses the problem that molecular sieves often require replacement and maintenance after prolonged use. In such cases, it is necessary to remove the molecular sieve from the equipment. However, molecular sieves are often fixedly installed in dewatering equipment, making disassembly inconvenient and hindering the rapid installation and removal of molecular sieves.

[0034] Please see Figure 4 - Figure 5 As shown, this utility model also includes a second tank 11, with an air inlet pipe 24 fixedly installed at the bottom of the second tank 11 and an exhaust pipe 25 fixedly installed at the top of the second tank 11. A filter plate 22 is located between the air inlet pipe 24 and the exhaust pipe 25. Both the first tank 1 and the second tank 11 are provided with a movable groove 26, and a movable frame 21 is movably installed in the movable groove 26.

[0035] A connecting plate 27 is fixedly installed on the tank body 21. A lead screw 28 is movably installed between the connecting plates 27. A motor is fixedly installed on the connecting plate 27, and the output end of the motor is fixedly connected to the lead screw 28. A movable nut 29 is movably installed on the lead screw 28 via threads. The lead screw 28 and the movable nut 29 form a drive structure for the lead screw 28 via threads. The threads are not shown in the figure. That is, when the motor drives the lead screw 28 to rotate, the movable nut 29 moves on the lead screw 28, thereby driving the movable frame 21 to move in the movable groove 26.

[0036] It should be noted that sealing strips are fixedly installed on the edges of the moving slot 26. When the moving frame 21 is in place, the sealing strips fit into the moving frame 21, thereby ensuring the sealing of tank 1 and tank 2 11 during operation.

[0037] A limiting plate 30 is fixedly installed on the movable frame 21. The limiting plate 30 is fixedly connected to the movable nut 29. There are two filter plates 22, which are located on both sides of the limiting plate 30. By using and regenerating the two filter plates 22 alternately, the processing efficiency of crude benzene is effectively improved.

[0038] The specific principle of filter plate 22 regeneration is as follows: heating the molecular sieve causes the adsorbed moisture or impurities to evaporate, restoring the adsorption performance of the molecular sieve. This is achieved by introducing high-temperature hot air through the air inlet pipe 24 at the bottom of the tank. Under the action of the hot air, the moisture and impurities evaporate and are discharged from the exhaust pipe 25 at the top, thereby realizing the regeneration of filter plate 22.

[0039] First, crude benzene is introduced into tank 1 and filtered through filter plate 22 before being discharged. The filter plate 22 absorbs moisture from the crude benzene, thus dehydrating it. After a period of use, the moving frame 21 is moved, causing the filter plate 22 that needs to be regenerated to move into tank 21. At this time, another filter plate 22 that has been regenerated moves into tank 1, and the filter plate 22 is regenerated through tank 21. The above steps are repeated to achieve continuous dehydration of crude benzene and effectively improve the crude benzene treatment efficiency.

[0040] Combining Examples 1 and 2, the filter plate 22 absorbs moisture from the crude benzene, thereby dehydrating the crude benzene. After a period of use, the moving frame 21 moves, moving the filter plate 22 that needs to be regenerated into the tank 11. At this time, another filter plate 22 that has been regenerated moves into the tank 1. The filter plate 22 is then regenerated in the tank 11. The above steps are repeated to achieve continuous dehydration of the crude benzene, effectively improving the crude benzene processing efficiency. At the same time, it is only necessary to push the locking block 23 to separate the locking block 23 from the surface of the filter plate 22, and the filter plate 22 can be removed from the moving frame 21, which is very convenient. At the same time, the disassembly process does not affect the crude benzene processing inside the tank 1, making it highly practical.

[0041] The working process and principle of this utility model are as follows:

[0042] First, the filter plate 22 absorbs the moisture in the crude benzene, thereby dehydrating the crude benzene. After a period of use, the moving frame 21 moves, moving the filter plate 22 that needs to be regenerated into the tank 11. At this time, another filter plate 22 that has been regenerated moves into the tank 1. The filter plate 22 is then regenerated through the tank 11. The above steps are repeated to achieve continuous dehydration of crude benzene and effectively improve the crude benzene treatment efficiency.

[0043] Furthermore, simply push the locking block 23 to separate the locking block 23 from the surface of the filter plate 22, and the filter plate 22 can be taken out from the moving frame 21, which is very convenient. At the same time, the disassembly process does not affect the processing of crude benzene inside the tank 1, making it highly practical.

[0044] In other words, by setting the adjustment component 2, this utility model not only effectively improves the crude benzene processing efficiency, but also enhances the overall practicality of the equipment.
