Description

Technical Field

[0001] This utility model relates to the field of catalyst support structure technology, specifically a catalyst support structure. Background Technology

[0002] Catalyst support structures refer to the materials or designs used to support catalysts, commonly used in catalytic reactions in the chemical industry. These support structures can be made of various shapes and materials, such as porous ceramics, metal meshes, and metal foams. Their main function is to provide a stable surface that allows catalyst particles to be effectively exposed to the reactants, and to provide good mass and heat transfer characteristics to enhance the efficiency and selectivity of the catalytic reaction. The design of these support structures depends on the specific reaction conditions, catalyst characteristics, and desired reaction products.

[0003] Patent application number "CN201820422772.8" describes "a catalyst support structure in a reactor, including a catalyst layer disposed at the upper part of the reactor, a high-temperature resistant steel plate disposed at the bottom end of the catalyst layer, and a heat-conducting pipe disposed in the middle of the reactor. A fixed seat for sliding the high-temperature resistant steel plate is disposed on the inner wall of the reactor along its circumference. Several elastic elements connected to the bottom end of the high-temperature resistant steel plate are disposed on the fixed seat along the circumference of the reactor. A limiting plate for horizontal up-and-down sliding of the high-temperature resistant steel plate is also disposed at the bottom end of the high-temperature resistant steel plate and is slidably connected to the fixed seat. The key point of the technical solution is that it has the advantage of reducing the probability of the center of the high-temperature resistant steel plate sinking."

[0004] However, the support structure of the catalyst mentioned above does not have a porous surface, so it cannot increase the reaction rate by increasing the surface area of ​​the catalyst in contact with the reactants. Furthermore, the support structure cannot promote the diffusion of reactants to the catalyst surface or allow products to diffuse away from the catalyst surface, and it also results in the inability to effectively conduct heat and maintain a uniform reaction temperature.

[0005] Therefore, this invention provides a catalyst support structure to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a catalyst support structure that solves the problem mentioned above where the catalyst support structure lacks a porous surface, thus failing to increase the reaction rate by increasing the surface area in contact between the catalyst and the reactants.

[0008] Preferably, the lower support seat is rotatably connected to the upper support cover via a hinge, and the lower support seats on the bearing seat are symmetrically arranged at both ends of the bearing seat via a shaft.

[0011] Preferably, a top cover is detachably connected to the top of the outer layer of the tank, and a fixing groove matching the rotating shaft bracket is opened in the middle of the top cover.

[0013] Beneficial effects

[0014] This invention provides a catalyst support structure. Compared with the prior art, it has the following advantages:

[0015] (1) The catalyst support structure fixes the catalyst inside the lower support base and the upper support cover by fixing the fastener and the groove on the lower support base. At the same time, the support base is inserted into the reaction tank from the side of the reaction tank. When the motor is started, the stirring rod inside the reaction tank stirs and forms a vortex. It also exerts downward pressure on the lower support base and the upper support cover above the stirring rod. This allows the lower support base and the upper support cover at both ends of the bearing seat to rotate inside the reaction tank, which can increase the surface area of ​​the catalyst in contact with the reactants, thereby increasing the reaction rate. This promotes the diffusion of reactants to the catalyst surface and allows the products to diffuse away from the catalyst surface.

[0016] (2) The catalyst support structure, through the rotor and differential inside the rotating shaft bracket, can provide sufficient power to the stirring rod on the rotating rod when the motor starts, thereby generating downward pressure on the lower support seat and the upper support cover. Under the action of the stirring rod, the reactants can be thoroughly mixed together, ensuring effective contact between the reactants, and helping to maintain the temperature uniformity of the reaction system, preventing temperature gradients during the reaction process, thereby ensuring the stability of the reaction conditions. At the same time, the heating strip between the outer layer and the inner layer of the tank makes the collision between molecules more frequent and more energetic, and heating inside the reactor can accelerate the reaction rate.

The catalyst support frame 4 includes a support base 401, a bearing seat 402 fixedly connected to the support base 401, a shaft 403 rotatably connected to the bearing seat 402, a lower support seat 404 fixedly connected to the shaft 403, an upper support cover 405 rotatably connected to the lower support seat 404, and a fixing tenon 406 fixedly connected to the upper support cover 405. A groove matching the fixing tenon 406 is provided at the position corresponding to the lower support seat 404 and the fixing tenon 406. The internal structure of the reaction vessel 3 is... A positioning seat 408 is fixedly connected to the lower support seat 404, and a positioning insertion hole 409 is fixedly connected to the positioning seat 408. The shaft 403 at the other end of the lower support seat 404 matches the positioning insertion hole 409. The lower support seat 404 is rotatably connected to the upper support cover 405 via a hinge. The lower support seats 404, which are movably connected to the bearing seat 402 via the shaft 403, are symmetrically arranged at both ends of the bearing seat 402. First, the catalyst is placed in the lower support seat 404. The fixing tenon 406 is fastened to the lower support seat 404 by the hinge. At the same time, the catalyst is fixed to the lower support seat 404 by the fixing tenon 406 and the groove on the lower support seat 404. The upper support cover 405 and the upper support base 401 are inserted into the reaction vessel 3 from the side. Due to the positioning pin 407 on the support base 401, the shaft 403 at the end of the upper support cover 405 can be inserted into the alignment hole 409 on the alignment seat 408 on the inner wall of the reaction vessel 3. When the motor 1 is started, the stirring rod 205 inside the reaction vessel 3 stirs and forms a vortex, which generates downward pressure on the lower support seat 404 and the upper support cover 405 above the stirring rod 205. Under the action of the bearing seat 402 and the shaft 403, the bearing seat 402... The lower support 404 and upper support cover 405 at both ends can rotate inside the reaction vessel 3. The porous structure on the catalyst support structure increases the surface area of ​​the catalyst in contact with the reactants, thereby increasing the reaction rate. The support structure can also rotate through the bearing seat 402, thereby promoting the diffusion of reactants to the catalyst surface and allowing products to diffuse away from the catalyst surface. At the same time, it can stably fix the catalyst particles, preventing them from breaking or being lost during the reaction due to collisions between particles or other reasons. The support structure can reduce the aggregation and sintering of catalyst particles and extend the service life of the catalyst.

[0026] Example 2:

[0027] Please see Figures 1 to 5This embodiment provides a technical solution based on Embodiment 1: A stirring mechanism 2 is fixedly connected to the reaction vessel 3. The stirring mechanism 2 includes a rotating shaft support 201, a rotor 202 fixedly connected to the rotating shaft support 201, a rotating rod 204 fixedly connected to the rotor 202, a differential 203 fixedly connected between the rotating rod 204 and the rotor 202, a stirring rod 205 fixedly connected to the rotating rod 204, and the other end of the rotating rod 204 fixedly connected to the output shaft of the motor 1. The reaction vessel 3 includes an outer tank layer 301, an inner tank layer 302 fixedly connected to the inside of the outer tank layer 301 via a heating strip, a tank bottom 303 fixedly connected to the bottom of the inner tank layer 302, a tank bottom seal 304 for easy cleaning opened in the core position of the tank bottom 303, a top cover 305 detachably connected to the top of the outer tank layer 301, a fixing groove matching the rotating shaft support 201 opened in the middle of the top cover 305, and multiple fixing brackets 306 for fixing equipment fixedly connected to the outer side of the outer tank layer 301. Positioning pins 407 for sealing and positioning are fixedly connected to the upper, lower, left, and right sides of the support base 401, and a fixing frame 306 is also fixedly connected to the outer side of the support base 401. The rotor 202 and differential 203 inside the rotating shaft bracket 201 provide sufficient power to the stirring rod 205 on the rotating rod 204 when the motor 1 starts, thereby generating downward pressure on the lower support base 404 and the upper support cover 405. Under the action of the stirring rod 205, the reactants can be thoroughly mixed together, ensuring effective contact between the reactants and helping to maintain the temperature uniformity of the reaction system, preventing temperature gradients during the reaction process, and thus ensuring the stability of the reaction conditions. At the same time, the heating strip between the outer layer 301 and the inner layer 302 of the tank makes the collision between molecules more frequent and more energetic. Heating inside the reactor can accelerate the reaction rate, and the fixing frame 306 on the outside of the outer layer 301 of the tank can effectively fix the equipment and prevent it from tipping over during use.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] Working principle: During operation, the catalyst is first placed in the lower support 404. The fixing tenon 406 is fastened to the lower support 404 by the hinge. At the same time, the catalyst is fixed inside the lower support 404 and the upper support cover 405 by the fixing tenon 406 and the groove on the lower support 404. Meanwhile, the support base 401 is inserted into the reaction vessel 3 from the side. Due to the positioning pin 407 on the support base 401, the shaft 403 at the end of the upper support cover 405 can be inserted into the alignment seat 408 on the inner wall of the reaction vessel 3. In the hole 409, when the motor 1 is started, the stirring rod 205 inside the reaction vessel 3 stirs and forms a vortex, generating downward pressure on the lower support 404 and upper support cover 405 above the stirring rod 205. Through the action of the bearing seat 402 and the shaft 403, the lower support 404 and upper support cover 405 at both ends of the bearing seat 402 can rotate inside the reaction vessel 3. The porous structure of the catalyst support structure increases the surface area of ​​contact between the catalyst and the reactants, thereby improving the reaction rate. Furthermore, this support structure can be extended through the bearing seat 409. 2. Rotation promotes the diffusion of reactants to the catalyst surface and allows products to diffuse away from the catalyst surface. It also stably fixes the catalyst particles, preventing them from breaking or being lost during the reaction due to particle collisions or other reasons. The support structure reduces catalyst particle aggregation and sintering, extending the catalyst's lifespan. The rotor 202 and differential 203 inside the rotating shaft support 201 provide sufficient power to the stirring rod 205 on the rotating rod 204 when the motor 1 starts, generating downward pressure on the lower support 404 and the upper support cover 405. Under the action of the stirring rod 205, the reactants are thoroughly mixed, ensuring effective contact between them and helping to maintain the temperature uniformity of the reaction system, preventing temperature gradients during the reaction and ensuring the stability of the reaction conditions. Simultaneously, the heating strip between the outer layer 301 and the inner layer 302 of the tank increases the frequency and energy of molecular collisions, accelerating the reaction rate through internal heating. Furthermore, the fixing frame 306 outside the outer layer 301 effectively secures the equipment, preventing tipping during use.
