Description

Technical Field

[0001] This application relates to the field of catalyst evaluation and screening technology, and more specifically, to an anti-clogging catalyst screening device based on solid-phase catalysis. Background Technology

[0002] Catalysts play a crucial role in modern chemical industry, significantly accelerating chemical reaction rates, improving reaction selectivity, and reducing the energy required for reactions to some extent. Catalyst screening equipment is used to evaluate the activity of various catalysts.

[0003] Catalyst screening and evaluation devices are essential tools for studying and testing the performance of various catalysts, including multiple reactor types such as fixed-bed reactors. However, in the actual evaluation and screening process of catalysts, especially when using fixed-bed reactors, reactor clogging is frequently encountered, which has become a significant factor limiting the accuracy of catalyst performance testing and affecting the reliability of evaluation results.

[0004] A fixed-bed reactor is filled with catalyst particles, allowing reactants to react continuously or intermittently through the catalyst in the bed. During this process, catalyst bed blockage occurs due to a variety of complex reasons, primarily including the following:

[0005] I. Catalyst Particle Crushing and Accumulation: During catalyst loading, reaction, or unloading, catalyst particles may be crushed by mechanical stress, forming fine particles. These particles are prone to accumulating inside the bed, thereby blocking the pores between catalysts and affecting the normal passage of materials.

[0006] 2. Formation of carbon deposits or sediments: In certain catalytic reactions, especially those involving high-temperature reactions such as organic matter cracking and dehydrogenation, carbon deposits or inorganic sediments are easily generated and adhere to the catalyst surface or pores. Over time, the accumulated substances can cause the catalyst bed pores to narrow or even become blocked.

[0007] 3. Insufficient purity of reactants: The raw materials contain dust, impurities or other solid particles that are not easy to participate in the reaction. These substances may remain in the catalyst bed during the reaction and cause blockage.

[0008] IV. Improper operating conditions: such as excessively high temperature causing catalyst deformation or melting, or excessively low flow rate causing material to remain in the bed for too long, increasing the probability of carbon buildup and deposit formation. Summary of the Invention

[0009] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an anti-clogging catalyst screening device based on solid-phase catalysis. This device effectively prevents clogging by detecting the flow rate of the reactor's inner wall pipes through air blowing and rationally formulating a cleaning plan based on the detection results.

[0010] This application is implemented as follows:

[0011] This application provides a solid-phase catalysis-based anti-clogging catalyst screening device, including a reactor component, a gas distribution component, a gas analysis component, and a central control unit for catalyst evaluation and screening. For storing the screening device, a frame is mounted on the outer surface of the reactor component. A movable support component is arranged on the left side of the frame, and multiple reaction storage components are arranged in a ring on the surface of the movable support component. A robotic arm is installed at the right end of the movable support component, and a clamping seat is installed in the middle of the left side of the movable support component. At the same time, an anti-clogging component and a dust removal component are respectively arranged on the left side of the movable support component.

[0012] According to the solid-phase catalysis-based anti-clogging catalyst screening device of the present application embodiment, a loading plate is installed on the left side of the inner cavity of the frame, and the loading plate includes a sliding support and an auxiliary support installed at the upper and lower ends on its left side, and a support plate is installed on the left side of the loading plate.

[0013] According to the embodiment of this application, the anti-clogging catalyst screening device based on solid-phase catalysis includes a mobile support component comprising a turntable for assembling reaction storage components, wherein an installation groove is provided on the outer side of the turntable surface, a storage tank is provided on the surface of the turntable and within the cavity of the installation groove, and a slip ring is provided on the outer surface of the turntable in an annular shape.

[0014] According to the solid-phase catalysis-based anti-clogging catalyst screening device of the present application embodiment, a drive motor is provided on one side of the bottom of the turntable, and a transmission component is provided on one side of the drive motor. The surface of the transmission component and the output end of the drive motor are both fitted with a transmission disk body. The reaction storage component is multiple and is inserted into the inner cavity of the mounting groove. Both ends of the inner cavity of the mounting groove are provided with abutment plates.

[0015] According to the solid-phase catalysis-based anti-clogging catalyst screening device of the present application embodiment, one end of the robotic arm is equipped with a drive carrier, while the output end of the robotic arm is equipped with a gripper.

[0016] According to the solid-phase catalysis-based anti-clogging catalyst screening device of the present application embodiment, a second drive motor is provided on the left side of the clamping seat, and an anti-slip pad is engaged on the inner surface of the second drive motor, and the anti-slip pad is made of flexible material.

[0017] According to an embodiment of this application, the anti-clogging catalyst screening device based on solid-phase catalysis includes an air pump for providing power, the output end of the air pump is connected to a main piping body, and the anti-clogging component also includes a fixed-distribution air cylinder and a down-flow air cylinder.

[0018] According to the solid-phase catalysis-based anti-clogging catalyst screening device of the present application embodiment, the surfaces of the fixed distribution gas cylinder and the down-flow gas cylinder are respectively fitted with a connecting plate one and a connecting plate two. The input end of the fixed distribution gas cylinder is connected to a gas guide pipe, and the surface of the down-flow gas cylinder is connected to a connecting pipe fitting. The other ends of the gas guide pipe and the connecting pipe fitting are respectively connected to the surface of the main distribution pipe body.

[0019] According to the solid-phase catalysis-based anti-clogging catalyst screening device of the present application embodiment, a flow sensor is installed in the middle of the surface of the lower flushing cylinder, and a valve body is installed at the bottom of the surface of the lower flushing cylinder.

[0020] According to the solid-phase catalysis-based anti-clogging catalyst screening device of the present application embodiment, the dust removal component includes a collection cylinder and an air flushing head, and the collection cylinder is equipped with a plurality of cleaning balls. The front end of the inner cavity of the collection cylinder is connected to a connecting plate three, which is made of a flexible elastic material. Meanwhile, the air inlet ends of the collection cylinder and the air flushing head are respectively connected to a gas supply pipe one and a gas supply pipe two.

[0021] The beneficial effects of this invention are:

[0022] 1. Drive motor one can drive the turntable to rotate, change the position of different reaction storage items, and use the robotic arm and gripper to send the reaction storage items into the clamping seat. The clamping seat and drive motor two work together to fix the reaction storage items inside and adjust the angle of the reaction storage items, reducing manual operation.

[0023] 2. When the reaction storage unit is in a vertical position, the air pump starts working and delivers a fixed amount of gas to the fixed gas cylinder. Because the fixed gas cylinder, the reaction storage unit, and the down-flow gas cylinder are interconnected in the vertical position, the gas delivered by the fixed gas cylinder flows through the reaction storage unit and is finally discharged through the down-flow gas cylinder. The down-flow gas cylinder can detect the flow rate of the incoming gas to determine the amount of gas entering the reaction storage unit over a period of time and whether there is any blockage inside. This allows for different clearing treatments based on the blockage situation.

[0024] 3. When the blockage is minor, the valve body controls the opening and closing of the lower flushing gas cylinder. Then, gas is intermittently introduced into the fixed gas cylinder and the lower flushing gas cylinder to flush the inside of the reaction storage container, increasing the convenience and efficiency of cleaning.

[0025] 4. When the blockage is severe, adjust the reaction storage unit to a horizontal position, with both ends in contact with the opposite end of the collection cylinder and the air purging head. The collection cylinder is ventilated to blow the cleaning balls stored inside into the reaction storage unit. Then, adjust the reaction storage unit to a vertical position and use the fixed air distribution cylinder and the downward air purging cylinder to ventilate intermittently, blowing the cleaning balls inside the reaction storage unit to float and impact, cleaning the impurities attached to the inner wall of the reaction storage unit.

[0026] In summary, this solution avoids the problem of blockage caused by long-term use of reaction storage devices. By detecting the degree of blockage in the reaction storage devices, a reasonable unblocking method is adopted. This reduces manual operation steps and enables convenient anti-blockage treatment of multiple reaction storage devices. Attached Figure Description

[0048] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] Example

[0050] like Figures 1-10 As shown, the solid-phase catalysis-based anti-clogging catalyst screening device according to an embodiment of this application includes a reactor component 100, a gas distribution component 110, a gas analysis component 120, and a central control central processor 130 for catalyst evaluation and screening. For storing the screening device, a frame 140 is mounted on the outer surface of the reactor component 100. The frame 140 is used to store and install the reactor component 100, the gas distribution component 110, the gas analysis component 120, the central processor 130, the frame 140, and the anti-clogging structure.

[0051] The frame 140 is divided into multiple cavities. The middle and right cavities are used to assemble the catalyst evaluation and screening equipment, while the left cavity can be used to assemble the anti-clogging and cleaning structure of the reaction storage unit 400.

[0052] Catalyst screening refers to comparing the catalytic effects of multiple catalysts on the same target substance and evaluating their activity to screen different types of catalysts.

[0053] When using reactor component 100, gas distribution component 110, gas analysis component 120, and central processing unit 130 to screen multiple catalysts for activity, the specific experimental steps for examining the activity of the screened catalysts are as follows:

[0054] 1. Catalyst loading: Weigh the required mass of catalyst and place it into reactor component 100. Insert a small amount of high-temperature cotton into both ends of the catalyst to fix the catalyst bed. Place the loaded tubular reactor into the heating furnace.

[0055] 2. Pipeline tightness check: First, introduce N2 to check the airtightness of the reaction device. Open the N2 cylinder valve, set the gas flow rate into the device on the mass flow meter, and seal the outlet. When the introduced gas causes the pressure gauge reading to reach 0.1 MPa, stop the gas supply. If the pressure does not drop within 10 minutes, it indicates that the reaction device is well sealed.

[0056] 3. Gas Mixing: Set the setpoint for each mass flow meter and perform gas mixing (using N2 as the carrier gas to simulate the flue gas flow rate required for the experiment). Once the gases are uniformly mixed and stabilized for a period of time, allowing the adsorbent to adsorb NO until saturation, the reduction of NO can be avoided as being caused by adsorption of the adsorbent.

[0057] IV. Heating reaction: The furnace temperature is set by programmable temperature rise, and the temperature is increased. After reaching the reaction temperature, the reaction is stabilized at each temperature for more than 1 hour before analysis.

[0058] V. NO Removal Rate Analysis: Samples were taken at the inlet and outlet, and the gas was collected in a 2L aluminum sampling bag. The NO concentration at the inlet and outlet was measured using a KM900 handheld flue gas analyzer to analyze the catalytic reduction activity of the catalyst for NO under different experimental conditions.

[0059] VI. Calculation of NO conversion rate: Based on the NO concentration values ​​before and after the reaction, calculate the NO conversion rate at each reaction temperature, which is defined as the denitrification rate. This data is used as an indicator to measure the catalyst activity.

[0060] Denitrification rate = Inlet NO concentration - Outlet NO concentration / Inlet NO concentration;

[0061] A loading plate 200 is installed on the left side of the inner cavity of the frame 140. The drive carrier 500 is mounted on the loading plate 200 to assemble the robotic arm 510. The loading plate 200 includes a sliding support 201 and an auxiliary support 202 installed at its upper and lower left ends. The outer surface of the turntable 310 is slidably fitted to the inner surface of the sliding support 201 to fix the mobile load-bearing component 300 as a whole. A support plate 210 is installed on the left side of the loading plate 200. The support plate 210 is installed on the surface of the frame 140 by bolt fasteners and is used to assemble the drive motor 600, the anti-blocking component 700 and the dust removal component 800.

[0062] When the reaction storage unit 400 is inserted into the mounting slot 311, its bottom makes sliding contact with the end of the auxiliary support 202.

[0063] A movable support assembly 300 is provided on the left side of the frame 140, and a plurality of reaction storage units 400 are arranged in a ring on the surface of the movable support assembly 300. The movable support assembly 300 includes a turntable 310 for assembling the reaction storage units 400, and an installation groove 311 is provided on the outer side of the surface of the turntable 310. The installation groove 311 is U-shaped. A storage tank 312 is provided on the surface of the turntable 310 and in the inner cavity of the installation groove 311. The storage tank 312 is used to store the abutment plate 330. A sliding ring 313 is arranged in a ring on the outer surface of the turntable 310. The sliding ring 313 is adapted to the sliding support 201, so that the turntable 310 is slidably mounted on the sliding support 201 through the sliding ring 313.

[0064] A drive motor 320 is mounted on one side of the bottom of the turntable 310. The drive motor 320 is bolted to the surface of the loading plate 200. A transmission component 321 is mounted on one side of the drive motor 320, and the end of the transmission component 321 is fixedly connected to the center of the bottom of the turntable 310. Both the surface of the transmission component 321 and the output end of the drive motor 320 are fitted with transmission discs 322. Preferably, the two transmission discs 322 are pulleys, connected by a belt drive, so that when the drive motor 320 rotates... The transmission disc 322 drives the transmission component 321 to rotate and turn the turntable 310. There are multiple reaction storage components 400 inserted into the inner cavity of the mounting groove 311. Both ends of the inner cavity of the mounting groove 311 are provided with abutment plates 330. The abutment plate 330 is composed of an abutment plate and a spring. The spring is installed in the inner cavity of the storage groove 312 to fix the abutment plate 330 as a whole. The abutment plate 330 abuts against the reaction storage component 400 when it is inserted into the mounting groove 311, increasing the stability of the reaction storage component 400 in the mounting groove 311.

[0065] A robotic arm 510 is installed at the right end of the mobile support assembly 300. The drive carrier 500 is used to deliver the reaction storage unit 400 stored on the mobile support assembly 300. The drive carrier 500 is installed at one end of the robotic arm 510, and the gripper 520 is installed at the output end of the robotic arm 510. The robotic arm 510 is installed on the surface of the loading plate 200. In this way, the robotic arm 510 and the gripper 520 can work together to adjust the reaction storage unit 400 in the mounting slot 311 so that it can enter the anti-slip pad 620.

[0066] The robotic arm 510 and gripper 520 are mechatronic devices that simulate the movements of human hands and arms and perform various specified physical tasks by grasping, moving objects, operating tools, or according to a predetermined program or information fed back by sensors.

[0067] The robotic arm 510 consists of a series of interconnected joints and arm segments. Each joint can rotate or move independently, which gives the robotic arm 510 multiple degrees of freedom, enabling it to accurately position and manipulate objects in three-dimensional space.

[0068] The control system of the robotic arm 510 is responsible for receiving instructions, planning paths, calculating joint angles, and driving each joint through servo motors to achieve the predetermined motion trajectory.

[0069] The final drive carrier 500, robotic arm 510 and gripper 520 are existing mechanical equipment, and will not be described in detail in this solution;

[0070] A clamping seat 610 is installed in the middle of the left side of the mobile support assembly 300 for clamping and fixing the reaction storage container 400 conveyed by the drive carrier 500. A second drive motor 600 is provided on the left side of the clamping seat 610. The second drive motor 600 is mounted on the surface of the support plate 210. An anti-slip pad 620 is snapped into the inner surface of the second drive motor 600. The anti-slip pad 620 is made of a flexible material, such as rubber or sponge. When the reaction storage container 400 enters the clamping seat 610, the anti-slip pad 620 is flexible and can be compressed to stably place it in the clamping seat 610.

[0071] Meanwhile, on the left side of the mobile bearing assembly 300, there are anti-blocking components 700 and dust removal components 800, which are used together to clean the internal dust in a reasonable and effective manner according to the gas flow rate of the reaction storage container 400.

[0072] The anti-clogging component 700 includes an air pump 710 for providing power. The output end of the air pump 710 is connected to a main piping body 711 for delivering the generated gas. The anti-clogging component 700 also includes a fixed-distribution air cylinder 720 and a downward-flowing air cylinder 730. The fixed-distribution air cylinder 720 and the downward-flowing air cylinder 730 are symmetrically arranged with the clamping seat 610 as the base point. The distance between the fixed-distribution air cylinder 720 and the downward-flowing air cylinder 730 on opposite sides is greater than the length of the reaction storage unit 400. Thus, when the reaction storage unit 400 is inserted into the clamping seat 610, its upper end contacts the bottom of the fixed-distribution air cylinder 720, while the lower end of the reaction storage unit 400 contacts the bottom of the downward-flowing air cylinder 730, so as to facilitate subsequent gas delivery.

[0073] As a further optimization of this solution, a gas flow monitoring component is installed at the output end of the fixed-distribution gas cylinder 720, which can detect the gas flow rate sent into the fixed-distribution gas cylinder 720 and control the gas flow rate of the fixed-distribution gas cylinder 720.

[0074] The surfaces of the fixed-dispensing air cylinder 720 and the down-pumping air cylinder 730 are respectively fitted with connecting plate 1 721 and connecting plate 2 731, which are respectively connected to the surface of the support plate 210. The input end of the fixed-dispensing air cylinder 720 is connected to the air guide pipe 722, and the surface of the down-pumping air cylinder 730 is connected to the connecting pipe fitting 732. The other ends of the air guide pipe 722 and the connecting pipe fitting 732 are respectively connected to the surface of the main piping body 711. Thus, the gas drawn in by the air pump 710 passes through the main piping body 711 and can be diverted into the air guide pipe 722 and the connecting pipe fitting 732, and sent into the fixed-dispensing air cylinder 720 and the down-pumping air cylinder 730 respectively.

[0075] A flow sensor 750 is mounted in the middle of the surface of the down-pump air cylinder 730, and a valve body 740 is mounted at the bottom of the surface of the down-pump air cylinder 730.

[0076] The dust removal assembly 800 includes a collection cylinder 810 and an air-purifying head 820. The collection cylinder 810 is equipped with multiple cleaning balls and is used to store the cleaning balls. The air-purifying head 820 is connected to an air pump 710 and is used to provide power to the cleaning balls. A connecting plate 3 811 is connected to the outer front end of the inner cavity of the collection cylinder 810. The connecting plate 3 811 is made of a flexible elastic material, which can be bent under pressure and reset when there is no pressure. At the same time, the air inlet ends of the collection cylinder 810 and the air-purifying head 820 are respectively connected to an air supply pipe 1 812 and an air supply pipe 2 821. The other ends of the air supply pipe 1 812 and the air supply pipe 2 821 are respectively connected to the surface of the main piping body 711 and the connecting pipe fitting 732.

[0077] To control the opening and closing of each pipeline, the surfaces of the main piping body 711, the gas guide pipe 722, the connecting pipe fitting 732, the first gas transmission pipe 812, and the second gas transmission pipe 821 are all equipped with solenoid valve bodies to control the opening and closing of their internal cavities.

[0078] Finally, when the reaction storage unit 400 is in a horizontal position from a vertical position, its two ends contact the opposite ends of the collection cylinder 810 and the air inlet 820. Air is circulated through the collection cylinder 810, which blows the cleaning balls stored inside into the reaction storage unit 400. After the reaction storage unit 400 is adjusted to a vertical position, air is circulated intermittently through the fixed air cylinder 720 and the downward air inlet 730 to blow the cleaning balls inside the reaction storage unit 400 to move and clean the impurities attached to the inner wall of the reaction storage unit 400, thus preventing the reaction storage unit 400 from becoming clogged after long-term use.

[0079] Specifically, the working principle of this solid-phase catalysis-based anti-clogging catalyst screening device is as follows:

[0080] When cleaning the reaction storage unit 400, the drive motor 320 can drive the turntable 310 to rotate, change the position of different reaction storage units 400, and use the robotic arm 510 and gripper 520 to send the reaction storage unit 400 into the clamping seat 610. The clamping seat 610 and the drive motor 600 cooperate to fix the reaction storage unit 400 inside and adjust the angle of the reaction storage unit 400.

[0081] When the reaction storage unit 400 is in a vertical position, the air pump 710 starts working to deliver a metered amount of gas to the fixed gas cylinder 720. Since the fixed gas cylinder 720, the reaction storage unit 400, and the downpour gas cylinder 730 are interconnected in the vertical position, the gas delivered by the fixed gas cylinder 720 flows through the reaction storage unit 400 and is finally discharged through the downpour gas cylinder 730. The downpour gas cylinder 730 can detect the flow rate of the incoming gas to determine the amount of gas entering the reaction storage unit 400 at one end of a time and to determine whether there is a blockage inside. If a blockage occurs, the following treatment is performed.

[0082] When the blockage is minor, the valve body 740 controls the opening and closing of the lower flushing gas cylinder 730, and then intermittently introduces gas into the fixed gas cylinder 720 and the lower flushing gas cylinder 730 to flush the inside of the reaction storage container 400 with gas.

[0083] When the blockage is severe, the reaction storage unit 400 is adjusted to a horizontal position, with its two ends contacting the opposite ends of the collection cylinder 810 and the air inlet 820. The collection cylinder 810 is ventilated to blow the cleaning balls stored inside into the reaction storage unit 400. Then, the reaction storage unit 400 is adjusted to a vertical position, and the fixed air cylinder 720 and the downward air inlet 730 are used to ventilate intermittently, causing the cleaning balls inside the reaction storage unit 400 to float and impact, cleaning the impurities attached to the inner wall of the reaction storage unit 400, and preventing the reaction storage unit 400 from becoming blocked after long-term use. In this way, a reasonable unblocking method is used to prevent blockage of the reaction storage unit 400 at different levels of blockage, thereby reducing manual operation steps and conveniently preventing blockage of multiple reaction storage units 400.
