Description

Technical Field

[0001] This utility model relates to the field of combined internal components technology, and more specifically to a combined internal component of a curved baffle and a guide tube. Background Technology

[0002] A hydrolysis tower is a device that processes materials through a hydrolysis reaction (the decomposition of substances by reacting with water). It is commonly used in feed processing, oleochemicals, coal chemicals, urea production, and environmental desulfurization. The internal components of a hydrolysis tower are the core components for achieving efficient mass transfer, reaction control, and stable operation. Their design must consider both the characteristics of the hydrolysis reaction (such as high temperature, high pressure, and corrosive media) and mass transfer efficiency. The main internal components of a hydrolysis tower include baffles, liquid distributors, packing support / compacting devices, liquid collection and redistribution devices, demisters, and gas inlet and outlet devices. Among these, baffles (such as bow-shaped plates or corrugated plates) disrupt laminar flow through structured sections, reducing the deposition of catalyst powder or fouling on the plate surface and thus preventing clogging. The curved surface design of the baffles (such as trapezoidal, toothed, or bow-shaped protrusions) can extend the flow path of gas or liquid, improving separation efficiency.

[0003] For example, the existing technology disclosure number CN210689298U discloses an environmentally friendly heat exchange device for a hydrolysis tower. This utility model has a simple structure, low manufacturing cost, high reliability, and strong adaptability. Furthermore, the continuous spiral baffle in the device enhances the efficiency of heat transfer and heat dissipation, and saves energy and reduces emissions.

[0004] However, the existing technology described above still has the following problems in use: the baffles and guide pipes in the traditional hydrolysis tower are stationary, and the liquid flows along a fixed path, which leads to a shortened contact time between the liquid and the reactants, incomplete hydrolysis reaction, and reduced product conversion rate. Based on this, the present invention provides a curved baffle and guide pipe combination internal component with high hydrolysis reaction efficiency. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a combination of a curved baffle plate and a flow guide pipe. By using a flow divider and a spiral curved panel to form the internal component, the hydrolysis reaction efficiency can be improved. An electric push rod drives the support rod to move up and down. The moving spiral curved panel can continuously change the flow direction and speed of the liquid, making the contact between the gas-liquid or liquid-solid phases more sufficient, thereby improving the reaction efficiency. It can also disturb the liquid, reducing the risk of scaling and accumulation, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a curved baffle and guide pipe combination internal component, including a mounting plate, a support rod fixedly provided at the bottom center of the mounting plate, a spiral curved panel fixedly provided on the outer wall of the support rod, a plurality of evenly distributed through holes opened on the surface of the spiral curved panel, a plurality of evenly distributed diverter pipes sleeved on the outer wall of the support rod, the plurality of diverter pipes being installed at the bottom of the mounting plate, a mounting block connected to the top of the mounting plate, a mounting groove opened at the bottom center of the mounting block, an electric push rod fixedly provided inside the mounting groove, the bottom end of the piston rod of the electric push rod being fixed to the top of the mounting plate, and a limiting component provided at the bottom of the support rod.

[0007] In a preferred embodiment, the limiting component includes a limiting block, a first limiting hole is provided at the top center of the limiting block, and a first limiting rod adapted to the first limiting hole is fixed at the bottom end of the support rod. The first limiting rod is disposed in the first limiting hole, and the support rod is limited by the first limiting rod, thereby improving the stability of the movement of the spiral curved panel.

[0008] In a preferred embodiment, the bottom of the mounting block is provided with a plurality of second limiting holes arranged in a circular array. Each second limiting hole is provided with a second limiting rod. The bottom end of the second limiting rod is fixed to the top of the mounting plate. The second limiting rod can limit the movement of the mounting plate, thereby improving the stability of the movement of the support rod and the spiral curved panel.

[0009] In a preferred embodiment, a sealing cover is connected between the bottom of the mounting block and the top of the mounting plate, and between the support rod and the limiting block. The number of sealing covers at the bottom of the mounting block is set to multiple, and the multiple sealing covers are respectively fitted over the electric push rod and the second limiting rod. By covering the electric push rod, the support rod and the second limiting rod with the sealing covers, it is possible to prevent them from being contaminated by liquid.

[0010] In a preferred embodiment, the bottom of the limiting block has multiple openings arranged in a circular array. The openings can reduce the weight of the limiting block and facilitate the flow of liquid.

[0011] In a preferred embodiment, both the top of the mounting block and the top of the limiting block are provided with a plurality of fixing holes arranged in a ring array to improve the stability of the mounting block and the limiting block.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model uses a diversion pipe and a spiral curved panel as internal components to improve the efficiency of hydrolysis reaction. The support rod is driven to move up and down by an electric push rod. The moving spiral curved panel can continuously change the flow direction and speed of the liquid, so that the contact between the gas-liquid or liquid-solid phases is more sufficient, thereby improving the reaction efficiency. It can also disturb the liquid and reduce the risk of scaling and accumulation.

[0014] 2. The first and second limiting rods act as limiters when the support rod and mounting plate move, thereby improving the stability of the movement of the support rod and the spiral curved panel, and thus ensuring the normal progress of the hydrolysis reaction. Attached Figure Description

[0022] 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.

[0023] Refer to the instruction manual appendix Figures 1-5This utility model provides a curved baffle and guide pipe combination internal component, including a mounting plate 1, a support rod 2 fixedly provided at the bottom center of the mounting plate 1, a spiral curved panel 3 fixedly provided on the outer wall of the support rod 2, a plurality of evenly distributed through holes 4 opened on the surface of the spiral curved panel 3, a plurality of evenly distributed diverter pipes 5 sleeved on the outer wall of the support rod 2, the plurality of diverter pipes 5 are all installed at the bottom of the mounting plate 1, a mounting block 6 connected to the top of the mounting plate 1, a mounting groove 7 opened at the bottom center of the mounting block 6, an electric push rod 8 fixedly provided inside the mounting groove 7, the bottom end of the piston rod of the electric push rod 8 being fixed to the top of the mounting plate 1, and a limiting component 9 provided at the bottom of the support rod 2.

[0024] In practical use, multiple distribution pipes 5 are used to evenly deliver the liquid into the tower. The evenly falling liquid can fully contact the packing material inside the tower, thereby improving the hydrolysis reaction efficiency. Then, the falling liquid contacts the spiral curved panel 3 on the support rod 2. The spiral curved panel 3 allows the liquid to flow in a curved or spiral shape within the hydrolysis tower, thereby increasing the flow path length and turbulence within the tower. Furthermore, the centrifugal force and shear force generated when the liquid flows along the curved surface can peel off the dirt layer on the surface of the spiral curved panel 3. At the same time, the design of the spiral curved panel 3 without dead corners can... This effectively reduces the risk of solid particle accumulation. In addition, the electric push rod 8 drives the support rod 2 on the mounting plate 1 to move up and down reciprocally. The first limiting rod 93 at the bottom of the support rod 2 slides in the first limiting hole 92 of the limiting block 91, limiting its movement trajectory. This ensures that the spiral curved panel 3 rises and falls within the set range. The moving spiral curved panel 3 continuously changes the flow direction and speed of the liquid, thereby making the contact between the gas-liquid or liquid-solid phases more sufficient, thus improving the reaction efficiency. It can also disturb the liquid and reduce the risk of scaling and accumulation.

[0025] Refer to the instruction manual appendix Figures 3-5 The limiting component 9 includes a limiting block 91. The bottom of the limiting block 91 has multiple openings 13 arranged in a ring array for normal liquid flow. The center of the top of the limiting block 91 has a first limiting hole 92. The bottom end of the support rod 2 is fixed with a first limiting rod 93 that matches the first limiting hole 92. The first limiting rod 93 is located inside the first limiting hole 92. The top of the mounting block 6 and the top of the limiting block 91 both have multiple fixing holes 14 arranged in a ring array.

[0026] The bottom of the mounting block 6 has a plurality of second limiting holes 10 arranged in a ring array. Each second limiting hole 10 is provided with a second limiting rod 11 inside. The bottom end of the second limiting rod 11 is fixed to the top of the mounting plate 1.

[0027] When the support rod 2 moves between the mounting block 6 and the limiting block 91, the first limiting rod 93 and the second limiting rod 11 can play a limiting role, thereby improving the stability of the movement of the support rod 2 and the spiral curved panel 3.

[0028] And, as Figure 4 As shown, sealing covers 12 are connected between the bottom of the mounting block 6 and the top of the mounting plate 1, and between the support rod 2 and the limiting block 91. The number of sealing covers 12 at the bottom of the mounting block 6 is set to multiple, and the multiple sealing covers 12 are respectively fitted on the outside of the electric push rod 8 and the second limiting rod 11. The sealing covers 12 are made of waterproof and corrosion-resistant materials. By covering the electric push rod 8, the support rod 2 and the second limiting rod 11 with the sealing covers 12, liquid can be prevented from affecting their use.

[0029] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
