Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of hydrolysis tower internals, and more specifically to a honeycomb perforated plate combined low scale inhibition hydrolysis tower internal. Background Technology
[0002] A hydrolysis tower is a tower-type device that provides specific reaction space and mass transfer conditions to enable the target substance in a liquid (or gas-liquid mixture) to undergo a hydrolysis reaction with water (or other reaction media). It is widely used in chemical, environmental protection, and pharmaceutical industries. Hydrolysis towers can hydrolyze large organic molecules (such as esters, amides, and polysaccharides) into smaller molecules or achieve the harmless treatment of pollutants. Through internal design (such as packing, perforated plates, and distributors), the contact between the liquid and the packing / catalyst is enhanced, thereby increasing the reaction rate.
[0003] Existing hydrolysis towers typically consist of a tower body, internal systems, inlet and outlet ports, and auxiliary devices. The internal systems include water distribution devices (such as porous distributors and spray heads) to ensure uniform liquid entry into the tower; mass transfer components (such as packing materials like Pall rings or structured packing materials like corrugated plates) or trays (such as sieve trays or valve trays) to increase the reaction contact area; and turbulence / anti-scaling structures (such as orifice plates and rotating components) to reduce scaling and enhance turbulence. The working principle is as follows: the liquid to be treated flows in from the top of the tower, is dispersed by the water distribution device, and then flows through the packing materials or trays to undergo a hydrolysis reaction with water (or catalyst).
[0004] For example, a novel blast furnace gas hydrolysis conversion tower with prior art disclosure number CN215250670U uses newly developed tower internals to guide the gas flow, allowing the gas flow to pass through the hydrolysis catalyst at a uniform and slow speed. This ensures the contact area and contact time between the gas and the hydrolysis catalyst, greatly improving the hydrolysis catalytic efficiency while reducing the gas resistance pressure drop. It can adapt to conditions such as large blast furnace gas flow, low pressure, and complex composition, thus improving the blast furnace gas hydrolysis conversion efficiency and meeting the requirements of blast furnace gas hydrolysis conversion.
[0005] However, the existing technology described above still has the following problems in use: the fixed pore size of the orifice plate in the traditional hydrolysis tower internals easily leads to the formation of scale from high-viscosity liquid residue, affecting the hydrolysis reaction rate and efficiency. Based on this, the present invention provides a honeycomb orifice plate combined low-scale-inhibiting hydrolysis tower internal. Utility Model Content
[0006] To overcome the aforementioned deficiencies of the prior art, this utility model provides a honeycomb perforated plate combined low-scale hydrolysis tower internal component. By combining the first and second honeycomb perforated plates into a hydrolysis tower internal component, the honeycomb-shaped pores can disperse the liquid, increase the contact area with the packing, and promote the hydrolysis reaction. At the same time, the second honeycomb perforated plate is driven to rotate by a rotating mechanism, so that the pore positions of the first and second honeycomb perforated plates are staggered to form turbulence, which can reduce scaling and improve the reaction rate and efficiency, thereby solving the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a honeycomb perforated plate combined low-scale hydrolysis tower internal component, including an installation ring. The installation ring has a first honeycomb perforated plate and a second honeycomb perforated plate distributed vertically inside. An annular groove is formed on the outer wall surface of the second honeycomb perforated plate. An external gear ring is fixedly installed inside the annular groove. The installation ring has an installation cavity inside. The installation cavity has a rotating mechanism inside. The rotating mechanism includes a rotating rod. The bottom end of the rotating rod is rotatably connected to the bottom wall of the installation cavity. A gear is fixedly sleeved on the rotating rod. The gear meshes with the external gear ring.
[0008] In a preferred embodiment, a motor is fixedly installed inside the mounting cavity, and the bottom end of the motor output shaft is fixed to the top end of the rotating rod. The motor drives the gear to rotate, thereby enabling automatic adjustment of the second honeycomb plate.
[0009] In a preferred embodiment, the outer wall surface of the mounting ring is provided with a plurality of mounting holes arranged in a ring array, and each mounting hole is provided with a fastening bolt. The first honeycomb plate is fixed to the mounting ring by the fastening bolt, which facilitates the disassembly and replacement of the first honeycomb plate.
[0010] In a preferred embodiment, the second honeycomb plate is mounted inside the mounting ring via a bearing, allowing the second honeycomb plate to rotate within the mounting ring.
[0011] In a preferred embodiment, a first rubber sealing ring for filling gaps is provided between the first honeycomb perforated plate and the mounting ring, and between the first honeycomb perforated plate and the second honeycomb perforated plate. The first rubber sealing ring between the first honeycomb perforated plate and the mounting ring can prevent liquid from flowing into the gap between them to a certain extent. The first rubber sealing ring between the first honeycomb perforated plate and the second honeycomb perforated plate can prevent liquid from flowing into the mounting cavity to a certain extent.
[0012] In a preferred embodiment, the top of the mounting ring is machined with fixing holes, and the number of fixing holes is set to multiple. The multiple fixing holes are distributed in a ring array on the mounting ring. Setting multiple fixing holes can improve the connection between the mounting ring and the hydrolysis tower.
[0013] In a preferred embodiment, a second rubber sealing ring is fitted on the outer wall of the mounting ring, which can play a sealing role between the second honeycomb plate and the inner wall of the hydrolysis tower.
[0014] The technical effects and advantages of this utility model are as follows:
[0015] This invention uses a combination of a first honeycomb perforated plate and a second honeycomb perforated plate to form the internal components of a hydrolysis tower. The honeycomb-shaped holes on the first and second honeycomb perforated plates allow the liquid to disperse and fall, increasing the contact area between the liquid and the packing material inside the tower, so that the hydrolysis reaction can proceed more fully. Furthermore, a rotating mechanism can be used to drive the second honeycomb perforated plate to rotate, so that the holes on the first and second honeycomb perforated plates are staggered. The staggered holes can play a certain role in turbulence, which can reduce the formation of fouling and further improve the rate and efficiency of the hydrolysis reaction.

[0023] 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.
[0024] Refer to the instruction manual appendix Figures 1-5This utility model provides a honeycomb perforated plate combined low scale inhibition hydrolysis tower internal component, including an installation ring 1. The installation ring 1 has a first honeycomb perforated plate 2 and a second honeycomb perforated plate 3 distributed vertically inside. The outer wall surface of the second honeycomb perforated plate 3 has an annular groove 4. An external gear ring 5 is fixedly installed inside the annular groove 4. The installation ring 1 has an installation cavity 6. The installation cavity 6 has a rotating mechanism 7 inside. The rotating mechanism 7 includes a rotating rod 71. The bottom end of the rotating rod 71 is rotatably connected to the bottom wall of the installation cavity 6. A gear 72 is fixedly sleeved on the rotating rod 71. The gear 72 meshes with the external gear ring 5. A motor 73 is fixedly installed inside the installation cavity 6. The bottom end of the output shaft of the motor 73 is fixed to the top end of the rotating rod 71.
[0025] The top of the mounting ring 1 is machined with fixing holes 11. The number of fixing holes 11 is set to multiple, and the multiple fixing holes 11 are distributed in a ring array on the mounting ring 1. A second rubber sealing ring 12 is sleeved on the outer wall of the mounting ring 1. The second rubber sealing ring 12 can play a sealing role between the second honeycomb plate 3 and the inner wall of the hydrolysis tower.
[0026] In actual use, the staff fixes the mounting ring 1 inside the hydrolysis tower. During the operation of the hydrolysis tower, the liquid to be treated enters the tower from the inlet. Since the honeycomb-shaped holes on the first honeycomb plate 2 and the second honeycomb plate 3 are evenly distributed, the liquid can be dispersed when passing through the honeycomb-shaped holes under the action of gravity, which provides good conditions for the subsequent hydrolysis reaction. After passing through the first honeycomb plate 2 and the second honeycomb plate 3, the liquid forms many fine liquid flows, which can increase the contact area between the liquid and the packing in the tower, so that the hydrolysis reaction can be carried out more fully. In addition, the motor 73 can drive the rotating rod 71 to rotate. The gear 72 on the rotating rod 71 drives the outer gear ring 5 and the second honeycomb plate 3 to rotate together, so that the holes on the first honeycomb plate 2 and the second honeycomb plate 3 are staggered. The staggered holes can play a certain role in turbulence, which can reduce the formation of fouling and further improve the rate and efficiency of the hydrolysis reaction.
[0027] Refer to the instruction manual appendix Figure 5 The outer wall surface of the mounting ring 1 has a plurality of mounting holes 8 arranged in a ring array. Each mounting hole 8 is provided with a fastening bolt 9. The first honeycomb plate 2 is fixed to the mounting ring 1 by the fastening bolt 9. By using a plurality of fastening bolts 9 to fix the first honeycomb plate 2, the stability of the first honeycomb plate 2 can be improved. And by loosening the fastening bolts 9, the first honeycomb plate 2 can be disassembled and replaced.
[0028] The second honeycomb plate 3 is mounted inside the mounting ring 1 via a bearing. Specifically, the outer ring of the bearing is connected to the inner ring wall of the mounting ring 1, and the second honeycomb plate 3 is connected to the inner ring wall of the bearing, so that the second honeycomb plate 3 can rotate within the mounting ring 1.
[0029] like Figure 3 and Figure 5 As shown, a first rubber sealing ring 10 for filling gaps is provided between the first honeycomb perforated plate 2 and the mounting ring 1, and between the first honeycomb perforated plate 2 and the second honeycomb perforated plate 3. The first rubber sealing ring 10 between the first honeycomb perforated plate 2 and the mounting ring 1 can prevent liquid from flowing into the gap between them to a certain extent. The first rubber sealing ring 10 between the first honeycomb perforated plate 2 and the second honeycomb perforated plate 3 can prevent liquid from flowing into the mounting cavity 6 to a certain extent.
