Description

Technical Field

[0001] This utility model belongs to the field of catalyst regeneration technology, and in particular relates to a catalyst regeneration reactor. Background Technology

[0002] After prolonged operation, some catalysts develop a large amount of impurities on their surface, and their internal pores become clogged with contaminants, leading to catalyst failure and the inability to carry out catalytic reactions, thus affecting the company's production efficiency.

[0003] Catalyst cleaning is a crucial process in catalyst regeneration technology, used to unclog catalyst pores and remove contaminants. The cleaning effectiveness directly impacts the quality of the subsequent regenerated product. Current catalyst cleaning devices typically involve piling a large amount of catalyst in a mesh container. This accumulation reduces the contact area between the catalyst and the cleaning solution, leading to decreased cleaning efficiency. After cleaning, the mesh container usually requires additional tools for retrieval or a lifting device to remove it from the liquid surface and empty it, making the process cumbersome. Utility Model Content

[0004] To address the above problems, this invention provides a catalyst regeneration reactor.

[0005] This invention is implemented as follows: A catalyst regeneration reactor includes a shell for holding a cleaning liquid. An ultrasonic generator is installed inside the shell, generating a high-frequency electrical signal, which is then transmitted to a transducer via a connecting wire. The transducer converts the electrical signal into mechanical vibration, generating ultrasonic waves, which are then input into the cleaning liquid inside the shell via a coupling device. The ultrasonic vibration causes the cleaning liquid to rapidly rupture and cool, creating a powerful vortex. This vortex can penetrate the surface of the object being cleaned, completely removing dirt and contaminants. As the ultrasonic waves propagate in the cleaning liquid, they generate alternating positive and negative sound pressure, forming a jet that impacts the cleaned parts. Simultaneously, due to nonlinear effects, acoustic flow and micro-acoustic flow are generated, and ultrasonic cavitation at the solid-liquid interface produces high-speed micro-jet streams. All these effects can break down contaminants, remove or weaken boundary contaminant layers, increase stirring and diffusion, accelerate the dissolution of soluble contaminants, and enhance the cleaning effect of chemical cleaning agents. An inner cylinder is installed inside the shell for holding the catalyst. A sleeve is vertically installed in the upper middle part of the inner cylinder, and multiple frames are vertically and uniformly fixed to the outer edge of the sleeve. The frame is fixedly connected to the inner wall of the inner cylinder to ensure the stability of the frame position. A stainless steel mesh is fixedly installed inside the frame, dividing the inner cylinder into multiple areas for placing appropriate amounts of catalyst. The stainless steel mesh is sturdy, durable, and has a long service life. An internal thread is provided inside the sleeve, and a screw is installed through the vertical thread of the sleeve to ensure the stability of the screw position. A plug is fixedly installed at the lower end of the screw. A discharge hole is opened at the middle of the lower end of the inner cylinder, and the plug corresponds to the position of the discharge hole. The plug passes through the discharge hole, and the screw rotates accordingly. The screw drives the block to move up and down. When the screw drives the block to move upward, the block blocks the discharge hole. When the screw drives the block to move downward, the block disengages from the discharge hole. The upper part of the block is a frustum-shaped cylinder that is narrower at the top and wider at the bottom. A discharge groove is provided between the bottom of the inner cylinder and the lower end of the sleeve at the upper opening of the discharge hole. The discharge groove is connected to the discharge hole. When the block blocks the discharge hole, the upper part of the block blocks the discharge groove. When the block disengages from the discharge hole, the catalyst in the inner cylinder is discharged along the discharge groove and the discharge hole. The inner cylinder wall is densely covered with mesh holes to facilitate the flow of cleaning fluid.

[0006] Preferably, a handle is fixedly provided at the upper end of the screw to facilitate pulling and rotating the screw.

[0007] Preferably, a heating device is provided inside the bottom of the housing to heat the cleaning fluid and improve cleaning efficiency.

[0008] Preferably, a drain pipe is provided at the bottom of the housing, and a shut-off valve is provided on the drain pipe. When the shut-off valve is opened, the cleaning fluid is discharged along the drain pipe.

[0009] Preferably, multiple support rods are vertically and evenly fixed at the bottom of the shell, and multiple slots are evenly opened at the lower end of the inner cylinder. The positions of the support rods and the slots correspond to each other. The support rods are inserted into the slots to support the inner cylinder, ensuring reliable contact between the catalyst and the cleaning liquid, and ensuring the stability of the inner cylinder position.

[0010] Preferably, the diameter of the discharge hole is larger than the diameter of the sleeve to avoid clogging of the discharge hole during discharge.

[0011] The beneficial effects of this utility model are: the inner cylinder is divided into multiple areas by multiple stainless steel mesh panels, and a corresponding amount of catalyst is placed there, which improves the cleaning efficiency. At the same time, the stainless steel mesh panels are sturdy and durable with a long service life. By pulling the screw with the handle, the inner cylinder can be directly removed from the shell. The screw is rotated by the handle, causing the block to detach from the discharge hole. The catalyst in the inner cylinder is discharged along the discharge trough and discharge hole. The operation is convenient, time-saving and labor-saving. Attached Figure Description

[0013] To better understand the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, further illustrates this utility model.

[0014] like Figure 1 and 2The catalyst regeneration reactor shown includes a shell 1 for holding cleaning fluid. A drain pipe 14 is located at the bottom of the shell 1, and a shut-off valve 15 is installed on the drain pipe 14. Opening the shut-off valve 15 allows the cleaning fluid to drain out along the drain pipe 14. An ultrasonic generator 2 is installed inside the shell 1 and is electrically connected to a power source. The ultrasonic generator 2 generates a high-frequency electrical signal, which is then transmitted to a transducer via a connecting line. The transducer converts the electrical signal into mechanical vibration, generating ultrasonic waves. These ultrasonic waves are then input into the cleaning fluid inside the shell 1 through a coupling device. The vibration of the ultrasonic waves causes the cleaning fluid to rapidly rupture and cool, forming a powerful vortex. This vortex can penetrate the surface of the object being cleaned, completely removing dirt and contaminants. When the ultrasonic waves propagate in the cleaning fluid, they generate alternating positive and negative sound pressures, forming jets that impact the cleaned components. Simultaneously, due to nonlinear effects, acoustic flow and micro-acoustic flow are generated. Ultrasonic cavitation at the solid-liquid interface generates high-speed micro-jet streams. All these effects can destroy dirt, remove or weaken boundary contaminant layers, and increase... The stirring and diffusion process accelerates the dissolution of soluble contaminants and enhances the cleaning effect of chemical cleaning agents. An inner cylinder 3 is provided inside the shell 1 for placing the catalyst. A sleeve 4 is vertically installed in the upper middle part of the inner cylinder 3. Multiple frames 5 are vertically and evenly fixedly installed on the outer edge of the sleeve 4. The frames 5 are fixedly connected to the inner wall of the inner cylinder 3 to ensure the stability of the frame 5's position.

A discharge hole 9 is opened at the middle of the lower end of the inner cylinder 3. The plug 8 is positioned corresponding to the discharge hole 9. The plug 8 passes through the discharge hole 9. When the screw 7 rotates, it drives the plug 8 to move up and down. When the screw 7 drives the plug 8 to move upward, the plug 8 blocks the discharge hole 9. When the screw 7 drives the plug 8 to move downward, the plug 8 disengages from the discharge hole 9. The upper part of the plug 8 is a circle that is narrower at the top and wider at the bottom. A discharge groove 10 is formed between the bottom of the inner cylinder 3 and the lower end of the sleeve 4, located at the upper opening of the discharge hole 9. The discharge groove 10 is connected to the discharge hole 9. When the block 8 blocks the discharge hole 9, the upper part of the block 8 blocks the discharge groove 10. When the block 8 detaches from the discharge hole 9, the catalyst in the inner cylinder 3 is discharged along the discharge groove 10 and the discharge hole 9. The diameter of the discharge hole 9 is larger than the diameter of the sleeve 4 to prevent the discharge hole 9 from becoming blocked during discharge. The inner cylinder 3 has a dense mesh 11 on its wall to facilitate the flow of cleaning fluid.

[0015] A heating device 13 is provided inside the bottom of the housing 1. The heating device 13 is electrically connected to a power source to heat the cleaning solution and improve the cleaning efficiency.
