Description

Technical Field

[0001] This invention relates to the field of chemical equipment technology, and in particular to a tray layer of a sulfuric acid drying tower that is easy to maintain. Background Technology

[0002] Drying towers are crucial equipment in the production of organosilicon. Tower types include plate towers, packed towers, and spray towers. Plate towers, based on tray configuration, can be further categorized into sieve tray towers, valve tray towers, solid valve tray towers, bubble cap tray towers, and composite tray towers. In the gas-liquid mass transfer process of a plate tower, the liquid phase is always continuous, while the gas phase is dispersed. The trays are a vital component of the tower, providing sufficient contact between the gas and liquid phases to promote mass and energy transfer. Gas transfer in the liquid occurs through bubbling, and the degree of gas dispersion directly determines the gas-liquid mass transfer efficiency. Therefore, the dispersion rate and speed of gas in the drying tower are key indicators of its drying efficiency.

[0003] In absorption or drying towers, countercurrent flow design of gas and liquid helps optimize the mass transfer process. Taking a concentrated sulfuric acid drying tower as an example, the gas is introduced from the bottom of the tower and flows upwards gradually, forming a countercurrent contact with the concentrated sulfuric acid introduced from the top of the tower, thereby achieving a good drying effect.

[0004] A tray consists of trays and bubble caps. As gas rises and passes through each tray, it enters the liquid phase through the openings in the bubble cap structure. A bubble cap is a special device on the tray designed to disperse the gas into tiny bubbles. This design increases the gas-liquid contact area, facilitating more efficient absorption of gas components. Especially in gas drying, the openings in the bubble cap disperse the gas into small bubbles, effectively increasing the gas-liquid contact time and efficiency.

[0005] Concentrated sulfuric acid has a strong hydrophilicity, capable of forming hydrates or undergoing chemical reactions with water molecules, greatly enhancing the water absorption effect. Gas enters the liquid layer through side openings in the bubble cap, and upon contact with the concentrated sulfuric acid, water is rapidly absorbed, forming a drier gas phase. This efficient mass transfer gradually reduces the moisture content in the gas, while the rising gas undergoes repeated mass transfer processes in each tray, achieving further purification.

[0006] Inside the column, the liquid enters from the top and flows downwards layer by layer under gravity. As it passes through each tray, the liquid accumulates, forming a liquid layer of a certain thickness, providing a mass transfer environment for the rising gas. As the liquid flows downwards along the overflow weir, it continuously comes into contact with the newly entering gas, causing the high-concentration sulfuric acid liquid introduced from the top of the column to be gradually diluted during the mass transfer process layer by layer, while the moisture in the gas is gradually absorbed and removed.

[0007] Through repeated mass transfer across multiple trays, the moisture in the gas inside the drying tower is absorbed layer by layer by concentrated sulfuric acid, achieving the desired drying effect. Simultaneously, the gas, through the tower's counter-current operation design, continuously comes into contact with fresh sulfuric acid liquid, completing efficient mass transfer on each tray.

[0008] Chinese patent document CN209237661U discloses a stainless steel bubble cap tray. This invention relates to the field of bubble cap tray technology, including a bubble cap body, a mounting tray, and connecting studs. The mounting tray has a bubble cap mounting opening, and fixing holes are formed on both sides of the bubble cap mounting opening on the top surface of the mounting tray. The bubble cap body is installed in the bubble cap mounting opening through a mounting seat installed on its outer wall. The mounting seat and the fixing holes are fixedly connected by fixing screws. The bubble cap body is composed of combined bubble caps, and connecting studs are installed on the internal threads of the combined bubble caps.

[0009] During prolonged use, other substances in the gas can react with concentrated sulfuric acid and adhere to the pores of the aforementioned apparatus, affecting gas throughput. Therefore, regular cleaning of the bubble cap trays is necessary. Industrially, bubble cap trays are often fixed with screws or welding. However, since concentrated sulfuric acid is the drying liquid in the drying tower, it is highly corrosive, and screw fixing often leads to thread failure due to corrosion. Therefore, screw or welding connections make disassembly inconvenient, making bubble cap replacement cumbersome and hindering the cleaning and maintenance of the bubble cap trays. Summary of the Invention

[0010] The purpose of this invention is to provide a convenient-to-maintain tray layer for a sulfuric acid drying tower. A press-type locking mechanism enables the rotation of the rotating lock body, requiring no special tools for installation and disassembly, making operation simple and convenient. Once the rotating lock body is in place, it is firmly fixed in the transverse groove, preventing the bubble cap from loosening or falling off. This structure improves equipment safety and maintenance efficiency, showing significant advantages, especially in tower systems with complex operating conditions and frequent operations. Furthermore, the press-type locking mechanism prevents accidental movement of the rotating lock body, ensuring a stable connection of the bubble cap and avoiding a decrease in gas-liquid mass transfer efficiency or equipment failure due to insecure installation, thus solving the problems mentioned in the background art.

Detailed Implementation

[0036] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0037] Example 1: As Figures 1-6As shown, a convenient-to-maintain sulfuric acid drying tower includes a tray 1 and several bubble caps 2. The tray 1 has a gas passage 101 and several riser pipes 102 connected to it. The sidewalls of the bubble caps 2 have several toothed slits, and a locking mechanism 3 is connected to each bubble cap 2. The bubble caps 2 are connected to the riser pipes 102 via the locking mechanism 3. The locking mechanism 3 includes a rotary lock body 301, a pressing rod 302, and a driving block 303. The bottom of the rotary lock body 301 is connected to... There is a locking rod 304, and the inner wall of the air riser 102 is provided with a horizontal groove 103 and a vertical groove 104. The locking rod 304 can enter the horizontal groove 103 through the vertical groove 104. The pressing rod 302 is slidably engaged with the bubble body 2. The bottom of the pressing rod 302 is connected to a driving block 303, which is slidably engaged with the motion groove on the inner wall of the rotary lock body 301. The top of the pressing rod 302 is connected to a pressing head 305, and a return spring 306 is provided between the pressing head 305 and the bubble body 2.

[0038] The rotary lock body 301 is coaxially arranged with the bubble body 2. The horizontal groove 103 is an annular groove, and there are two vertical grooves 104 symmetrically arranged. The bottom end of the vertical groove 104 is connected to the horizontal groove 103. The locking rod 304 is symmetrically connected to the outer wall of the rotary lock body 301. The locking rod 304 slides into the horizontal groove 103 through the two vertical grooves 104.

[0039] The riser pipe 102 has a horizontal groove 103 and a vertical groove 104 inside. The vertical groove 104 provides vertical movement space for the rotary lock body 301. This structure is particularly crucial when installing and removing blister packs. Through the vertical groove 104, operators can easily push the rotary lock body 301 along the vertical groove 104, thereby aligning the blister pack 2 with the rotary lock body 301 and easily installing it, simplifying the installation process. In addition, the vertical groove 104 allows the rotary lock body 301 to move flexibly up and down in the riser pipe 102, helping operators to achieve alignment and docking when installing blister packs.

[0040] During installation, once the rotary lock body 301 reaches the designated position on the air riser pipe 102 via the vertical groove 104, it will rotate into the horizontal groove 103. The horizontal groove 103 provides space for the rotary lock body 301, enabling vertical locking. The locking rod 304 is fixed within the horizontal slide groove, thus achieving a locked state, stabilizing the position of the bubble body 2, and preventing possible loosening or dislocation during operation.

[0041] To facilitate the installation and removal of the blister pack 2, a press-type quick-release structure is adopted. This structure is connected to the rotary lock body 301. By pressing, the rotary lock body 301 is rotated to fix the overall structure.

[0042] The entire pressing part consists of two main components: a pressing lever 302 and a drive block 303. The pressing lever 302 serves as the operating end, triggering the pressing head 305 by manually applying force, thereby locking or unlocking the rotary lock body 301. The drive block 303 at the bottom of the pressing lever 302 is also a key transmission component, which engages with the spiral groove 308 in the lock body tube when pressed.

[0043] To convert the linear motion of pressing into rotational motion, a motion groove is designed in the rotary lock body 301, with the lower section of the motion groove being spiral-shaped. This spiral motion groove design enables the drive block 303 to move the rotary lock body 301 along a spiral path when pressed, thereby driving the pressing rod 302 to perform a series of linked actions.

[0044] In operation, the operator applies a downward force to the pressing rod 302. Since the rotary lock body 301 is fixed in the vertical position of the air riser 102, the force applied to the pressing rod 302 causes the drive body to move along the spiral groove 308, forcing the rotary lock body 301 to rotate. Regarding the design of the spiral groove 308, in order to enable the rotary lock body 301 to rotate 90°, the length of the spiral groove 308 is designed to be 1 / 4 of the inner circumference of the rotary lock body 301.

[0045] When the pressing body reaches the designated position, the angle of the spiral groove 308 stops the pressing rod 302 from moving downwards and triggers the rotation of the rotary lock body 301. At this time, the drive block 303 at the bottom of the pressing rod 302 drives the rotary lock body 301 to rotate 90° on the horizontal plane, completing the locking or unlocking action. This ingenious design avoids additional fasteners or complicated operations, and installation and disassembly can be completed simply by pressing.

[0046] The push rod 302 is coaxially arranged with the rotary lock body 301. The moving groove has a two-section structure, with the upper section being a straight groove 307 and the lower section being a spiral groove 308. The drive block 303 enters the spiral groove 308 through the straight groove 307. The length of the spiral groove 308 is 1 / 4 of the inner circumference of the rotary lock body 301, allowing the rotary lock body 301 to rotate from 0 to 90°. The upper and lower ends of the spiral groove 308 have different depths, with the upper end being deeper and the lower end being shallower. This difference in depth allows the push rod 302 to produce a more precise control effect during operation.

[0047] The bottom end of the pressing rod 302 is connected to a base 309. A cylindrical drive block 303 slides on the base 309. One end of a compression spring 310 is connected to the base 309, and the other end is connected to the drive block 303. The design of the compression spring 310 allows the cylindrical drive block 303 to better adapt to the depth changes of the spiral groove 308. During operation, the movement of the pressing rod 302 is not limited by the vertical direction, but relies on the depth changes of the spiral groove 308 to drive the rotary lock body 301 to rotate as a whole, thereby achieving rotary locking. Specifically, when the operator presses the pressing rod 302, the drive body starts to move from the deeper spiral groove 308, and rotates through the angled design, driving the rotary lock body 301 to rotate synchronously, thus causing the rotary lock body 301 to rotate in a predetermined direction.

[0048] Because the top of the pressing rod 302 is equipped with a return spring 306, the drive body is pushed back to the upper position at the lower end of the spiral groove 308 by the return spring 306, completing one reciprocating motion. This reciprocating motion design not only realizes the reset of the drive body, but also provides stability and consistency for repeated operation of the rotary lock body 301. When released, the return spring 306 will restore the drive body to the upper end of the groove, so that there is no need to reposition it in the next operation, saving operation time and improving installation efficiency.

[0049] A sliding sleeve 311 is connected to the blister body 2. An integrally formed nut 312 is connected above the sliding sleeve 311. The sliding sleeve 311 is inserted into the blister body 2 and has external threads. The nut 313 is threaded into the sliding sleeve 311 so that the sliding sleeve 311 is fixed to the blister body 2.

[0050] Example 2: Due to the resistance loss generated by the gas passing through the bubble cap 2 itself and the pressure drop generated by the gas overcoming the liquid on the tray, different tray layers have different pressures. Furthermore, during the drying process, due to the flow of the drying liquid, most of the gas exiting the bubble cap 2 flows in the same direction as the flow. This situation can lead to excessive local pressure and uneven pressure across the entire tray layer. In high-pressure areas, the gas outlet velocity increases, making it prone to mist entrainment. Most of the gas exiting the bubble cap 2 flows in the same direction as the flow, resulting in excessive local pressure and uneven pressure across the entire tray layer. If a single type of bubble cap 2 is used, the drying efficiency will be low. In this example, an adjustable-tooth bubble cap 2 structure is provided. A bubble cap 2 with a high porosity is used in areas with high gas pressure. By increasing the number of bubbles, the bubbling rate is increased, thus avoiding the above-mentioned defects. Specifically: It also includes a pressure regulating system 4; the pressure regulating system 4 includes a pressure plate 401, several pressure measuring instruments 402 are connected to the pressure plate 401, the top of the pressure measuring instruments 402 are connected to the bubble body 2; a transmission rod 403 is connected to the pressure plate 401, one end of the gear plate 404 is connected to an eccentrically set rotating shaft 405, the rotating shaft 405 is rotatably connected to the transmission rod 403, the gear plate 404 meshes with a gear 406, and the gear 406 is connected to the bubble body 2.

[0051] The blister body 2 includes an inner layer 201 and an outer layer 202. The inner layer 201 is provided with an inner toothed slot 203, and the outer layer 202 is provided with an outer toothed slot 204. The inner layer 201 and the outer layer 202 are movably connected so that the inner toothed slot 203 and the outer toothed slot 204 overlap or stagger. The top of the pressure measuring device 402 is connected to the outer layer 202.

[0052] The outer wall of the inner layer 201 is provided with an axial groove 205 and a radial groove 206, which are connected. The inner wall of the outer layer 202 is connected with a slider 207. The slider 207 on the outer layer 202 enters the radial groove 206 through the axial groove 205 so that the outer layer 202 slides radially along the inner layer 201.

[0053] When the pressure inside the blister pack 2 exceeds a set value, the gas pushes the pressure plate 401 upward. A spring structure in the pressure measuring device 402 causes the transmission rod 403 in the pressure plate 401 to move upward. The transmission rod 403 is connected to the gear plate 404, which is eccentrically mounted, causing the gear plate 404 to rotate. Gear 406 meshes with the gear plate, driving it to rotate. The rotation of gear 406 then drives the outer layer 202 of the blister pack 2 to rotate. The outer layer 202 rotates relative to the inner layer 201, changing the area of ​​the misalignment between the inner and outer toothed slots 203 and 204, thus adjusting the opening ratio.

[0054] Apart from the above, this embodiment is exactly the same as Embodiment 1, and will not be described again here.

[0055] Example 3: In the case of Example 2 above, it is impossible to fix the blister pack 2 to a specific opening ratio. However, this example avoids the above-mentioned defects. Specifically: The slider 207 is connected to the ball bearing 208 via an adjusting spring. The radial groove 206 is provided with a ball socket. When the outer layer 202 slides radially along the inner layer 201, the ball bearing 208 can be inserted into the ball socket. There are three ball sockets. When the ball bearing 208 falls into the first ball socket 209, it is set to the original opening ratio. At the same time, the first ball socket 209 serves as the initial point to facilitate sensing the adjustment height of the outer layer 202 relative to the inner layer 201, indicating that this is the rotation height. When the ball bearing 208 falls into the second ball socket 210, the opening ratio is 1.5 times the original opening ratio. When the ball bearing 208 falls into the third ball socket 211, the opening ratio is 0.5 times the original opening ratio.

[0056] The blister pack 2 is designed to consist of an outer layer 202 and an inner layer 201, which are connected by a groove and a slider 207. This allows the blister pack 2 to flexibly adjust its opening ratio after installation, thereby adjusting the gas flow rate and the degree of gas-liquid contact. The outer wall of the inner layer 201 is provided with an axial groove 205 and a radial groove 206, while the inner wall of the outer layer 202 is provided with a slider 207, which can slide within the axial groove 205 and the radial groove 206. During installation, the slider 207 of the outer layer 202 aligns with the axial groove 205 and moves along the direction of the axial groove 205. When it moves to the position of the radial groove 206, it can rotate left and right to control the opening ratio of the toothed slots. When rotating to the left, the inner toothed slot 203 is covered, and the opening ratio remains the same. When the bubble cap shell rotates to the right, the outer toothed slot 204 coincides with the inner toothed slot 203, allowing gas to pass through. At this time, the opening ratio is 1.5 times the original, which is more conducive to improving the gas throughput in high-pressure areas and also beneficial to pressure division, reducing mist entrainment. When the slider 207 moves to the lower end of the inner layer 201 and rotates, the outer toothed slot 204 coincides with the inner toothed slot 203, and the inner toothed slot 203 is partially covered. At this time, the opening ratio is 0.5 times the original, using a smaller opening ratio in low-pressure areas. Furthermore, because the shell slides down, the space of the bubble cap 2 is reduced, which is more conducive to the gas throughput in low-pressure areas.

[0057] The design of the opening ratio is based on the trend of pressure drop changes within the tower. Through subdivided stages, quantitative analysis is performed using simulation software to finally obtain a relatively balanced opening ratio.

[0058] This structure can switch between 0.5x, 1x, and 1.5x opening ratios to meet the needs of different pressure zones. It provides a fast passage in high-pressure zones and adaptability in low-pressure zones. Adjusting the bubble body 2 space and opening ratio optimizes gas-liquid contact efficiency and adapts to complex industrial operating conditions.

[0059] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent transformations or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
