Description

Technical Field

[0001] The utility model relates to the technical field of catalyst cleaning, in particular to a catalytic cracking catalyst regeneration cleaning device. Background Technique

[0002] At present, the development of the global refining industry faces many challenges such as new energy substitution and stricter requirements for energy conservation and emission reduction. Flexibly adjusting the cracking production plan, reducing carbon dioxide emissions, and slowing down climate change have become the only way for the refining industry to transform its economic growth mode and maintain sustainable development. Therefore, it is particularly important to effectively reduce carbon emissions in the process of petroleum refining and chemical production. The research on the low-carbon catalytic cracking scheme of reducing oil and increasing chemicals is an important task for refineries in the future. The carbon emissions in the heavy oil processing process are mainly the flue gas emissions of catalytic cracking burning, hydrogen production process, boilers and other equipment, as well as the energy consumption of the process. Among them, the catalytic cracking unit is the core equipment in the refinery. The carbon emissions caused by the burning of the catalytic cracking regenerator account for 24-55% of the total carbon emissions of the whole plant and nearly 1% of the total national carbon dioxide emissions, which is the key point of carbon emission reduction in the petrochemical industry.

[0003] After the catalyst has been in operation for a long time and fails, a large amount of impurities will adhere to its surface, and its internal pores will also be blocked by pollutants. Even some toxic and harmful ions will react with the catalyst after adsorption, resulting in catalyst deactivation. Catalyst cleaning is one of the important processes in catalyst regeneration technology, which is used to dredge the blocked pores of the catalyst and remove the pollutants on the catalyst. Its cleaning effect will directly affect the quality of the subsequent regenerated products.

[0004] A disclosed waste SCR denitration catalyst cleaning device (authorized announcement number: CN 212760008U) heats the cleaning liquid in the cleaning tank through a heating device, and then cooperates with a bubbling air pipe to generate a large number of bubbles in the cleaning tank, and uses the surging effect of the bubbles to clean the surface and pores of the regenerated catalyst module. The cooperation of the heating device and the bubbling air pipe in the utility model can effectively increase the number and density of the generated bubbles compared with a single bubbling air pipe, thereby optimizing the cleaning effect.

[0005] However, the above technical solution still has certain defects. The catalyst module is directly cleaned on the top of the support frame, and since the heating device heats the cleaning liquid to a certain temperature, other tools are needed to fish out the cleaned catalyst module, which takes a certain amount of time to take out the catalyst module. Similarly, the dirt cleaned from the catalyst module will stay in the corner formed by the support frame and the inclined groove, making it difficult to clean, and even adhering again when the catalyst module is cleaned next time. Therefore, a catalytic cracking catalyst regeneration cleaning device is proposed. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation of the present utility model.

[0027] The embodiments of the present utility model will be described below according to its overall structure.

[0028] A catalytic cracking catalyst regeneration and cleaning device, as Figures 1 to 6As shown, it includes a housing 100. An inner frame 110 is movably sleeved inside the housing 100. Two groups of electric push rods 120 are assembled on the outer wall of the housing 100. A connecting piece 121 fixed to the top end of the inner frame 110 is provided at the output end of each group of electric push rods 120. Notches 113 are formed on the front and rear outer walls of the inner frame 110. A filter frame 111 is slidably arranged near the bottom end inside the inner frame 110;

[0029] Two groups of bubbling air pipes 160 are fixed on the inner wall of the housing 100 on the front and rear sides of the inner frame 110. An input pipe 161 extending to the outside of the housing 100 is connected to the ends of the two groups of bubbling air pipes 160. A cleaning pipe 150 is fixed on the inner wall of the housing 100 above the bubbling air pipes 160. A plurality of water outlets 151 are connected to the outer wall of the cleaning pipe 150. Each group of water outlets 151 is inclined on the side of the cleaning pipe 150 close to the notch 113;

[0030] A water pump 190 is assembled on the inclined outer wall of the housing 100 near the bottom end. The input end of the water pump 190 is connected to the housing 100 through a pipeline. A branch pipe 130 connected to the two cleaning pipes 150 is provided at the output end of the water pump 190.

[0031] Put a certain amount of catalyst module into the inner frame 110. At the same time, heat the cleaning liquid to a certain temperature. At this time, an external air compressor sends compressed air into the bubbling air pipes 160. A large number of bubbles are generated through the bubbling air pipes 160. The surface and pores of the catalyst module to be regenerated are cleaned by using the bubble surging effect. At the same time, the ultrasonic vibration plate 180 works to emit ultrasonic waves, so that the dirt layer is dispersed, emulsified and peeled off to achieve the purpose of cleaning, so as to remove the pollutants attached to the surface of the catalyst module to be regenerated and in the pores and pore diameters of the catalyst module to be regenerated, so as to achieve the cleaning effect on the catalyst module to be regenerated;

[0032] After the cleaning is completed, control the electric push rod 120 to work. Its output end rises. Driven by the connecting piece 121, the inner frame 110 rises linearly, so that the catalyst module is dehydrated and drained. Then the catalyst module can be manually taken out. At the same time, the filter frame 111 can be pulled out to remove the dirt cleaned inside, improving the efficiency of taking out the catalyst module. At the same time, it avoids the dirt staying in the cleaning liquid, ensuring that the cleaning liquid can be recycled multiple times;

[0033] When the inner frame 110 rises, the water pump 190 will work synchronously, pumping the cleaning liquid at the bottom layer inside the housing 100 into the branch pipe 130, and flowing into the cleaning pipe 150 to rewash the catalyst module through the water outlets 151, so that the dirt on the catalyst module that rises and contacts the surface of the cleaning liquid is washed off again, ensuring higher quality of the cleaned catalyst module.

[0034] Please refer to Figure 2, the bottom end of the outer shell 100 is frustum-shaped, and a solenoid valve 140 is installed at the bottom end of the outer shell 100.

[0035] It can gather the cleaning liquid in the outer shell 100 towards the middle, making it approach the side of the solenoid valve 140, which is convenient for the internal cleaning liquid to be discharged through the solenoid valve 140.

[0036] Please refer specifically to Figure 1 , the free end of the input pipe 161 is docked with an external air compressor and a ventilation pipe through a three-way pipe.

[0037] It is convenient to increase the pressure and ventilate inside the bubbling air pipe 160 through the input pipe 161, so as to achieve the purpose of efficiently cleaning the catalyst module.

[0038] Please refer specifically to Figure 1 , a support frame 101 is fixed on the inner wall of the outer shell 100, and the top end of the support frame 101 is in contact with the bottom end of the inner frame 110.

[0039] It serves the purpose of supporting the inner frame 110 located inside the outer shell 100, thereby reducing the load on the electric push rod 120.

[0040] Please refer specifically to Figure 4 , ultrasonic vibration plates 180 are assembled on the front and rear inner walls of the outer shell 100 above the support frame 101, and heating devices 170 are assembled on the inner walls of the outer shell 100 on both sides of the ultrasonic vibration plates 180.

[0041] The heating device 170 is used in cooperation with the bubbling air pipe 160 to generate a large number of bubbles, and the surface and pores of the catalyst module to be regenerated are cleaned by using the bubble surging effect;

[0042] At the same time, the ultrasonic vibration plate 180 disperses, emulsifies and peels off the dirt layer to achieve the purpose of cleaning, so as to remove the pollutants attached to the surface of the catalyst module to be regenerated and in the pores and pore diameters of the catalyst module to be regenerated, so as to achieve the cleaning effect on the catalyst module to be regenerated.

[0043] Please refer specifically to Figure 6 , deflection pieces are rotatably connected to the front and rear inner walls of the inner frame 110, and the eccentric pieces are in contact with the upper half outer wall of the filter frame 111. The inner frame 110 is integrally made of a mesh plate structure.

[0044] Rotate the eccentric piece so that it no longer blocks the filter frame 111, so that the filter frame 111 can be pulled out from the inner frame 110, so that the dirt filtered by the inner frame 110 can be cleaned.

[0045] Please refer specifically to Figure 3 , baffles 112 are fixed on the front and rear outer walls of the inner frame 110, and the baffles 112 are located at a position close to the top end of the outer wall of the inner frame 110.

[0046] Block the gap between the inner frame 110 and the outer shell 100, improving the aesthetics while preventing other objects from entering and ensuring that the heating device 170 and the ultrasonic vibration plate 180 on its inner wall can work without being affected.

[0047] During use, place a certain amount of catalyst module into the inner frame 110. At the same time, heat the cleaning liquid to a certain temperature. At this time, an external air compressor sends compressed air into the bubbling air pipe 160, and a large number of bubbles are generated through the bubbling air pipe 160. The surface and pores of the catalyst module to be regenerated are cleaned by using the bubble surging effect. At the same time, the ultrasonic vibration plate 180 works to emit ultrasonic waves, so that the dirt layer is dispersed, emulsified and peeled off to achieve the purpose of cleaning, in order to remove the pollutants attached to the surface, pores and pore diameters of the catalyst module to be regenerated, so as to achieve the cleaning effect on the catalyst module to be regenerated.

[0048] After the cleaning is completed, control the electric push rod 120 to work. Its output end rises. Driven by the connecting piece 121, the inner frame 110 rises linearly, so that the catalyst module is dehydrated and drained. Then the catalyst module can be manually taken out. At the same time, the filter frame 111 can be pulled out to remove the dirt cleaned inside, improving the efficiency of taking out the catalyst module and avoiding the dirt remaining in the cleaning liquid, ensuring that the cleaning liquid can be recycled multiple times.

[0049] When the inner frame 110 rises, the water pump 190 will work synchronously, pumping the cleaning liquid at the bottom layer of the outer shell 100 into the branch pipe 130, and flowing into the cleaning pipe 150 to rewash the catalyst module through the water outlet head 151, so that the dirt on the catalyst module that rises and contacts the surface of the cleaning liquid is washed off again, ensuring that the quality of the cleaned catalyst module is higher. The parts not involved in this device are the same as the prior art or can be implemented by using the prior art.
