Description

Technical Field

[0001] This invention relates to a particulate carrier processing apparatus, belonging to the technical field of catalyst processing equipment. Background Technology

[0002] Impregnating carrier microparticles with active substances to obtain catalysts and other substances is a common practice in the chemical industry. Among them, carrier microparticles with porous structures, during the loading of effective components, are subjected to capillary forces, with the impregnating solution being drawn from the surface into the pores of the carrier. The effective components of the solute permeate and diffuse along the inner wall of the solution, and are then adsorbed, deposited, or ion-exchanged by the active sites on the surface of the carrier, or even react, ultimately resulting in the active components being loaded onto the carrier.

[0003] In catalyst preparation processes, impregnation can be divided into two methods: batch impregnation and continuous impregnation. Batch impregnation involves immersing the prepared catalyst support in a metal salt impregnation solution containing the active component for a specific time. After adsorption equilibrium is reached, the remaining liquid is removed, and the catalyst support is then subjected to drying, calcination, and activation processes to produce the catalyst product. Continuous impregnation processes, such as basket impregnation or chain impregnation, can be used for individual catalyst supports with a specific volume and shape.

[0004] In the existing technology, after the catalyst support has been impregnated for a certain period of time, it is usually taken out of the impregnation solution, left for a period of time, and then transferred to an oven for drying. After drying and other treatments, the catalyst support is processed into a finished product. This process is completed in batches, which takes a lot of time and results in low efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a particulate carrier processing apparatus that improves the continuity of the catalyst processing process, increases the overall processing efficiency, reduces the adhesion of the catalyst carrier to the inner wall of the tank during impregnation, and improves the yield of the catalyst carrier.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a particulate carrier processing device, comprising: a reaction vessel, wherein the reaction vessel containing material is installed on the top of a box, the material being a solid-liquid mixture of a catalyst carrier and an impregnation liquid, a star-shaped unloader is disposed between the reaction vessel and the box, and a first discharge port is opened on the side wall of the box;

[0007] A filter plate with filter holes is located inside the housing and below the star-shaped unloader. The filter plate is set at an angle. A partition plate with a second discharge port is set between the bottom of the filter plate and the first discharge port. A drying cradle with ventilation strips is set between the first discharge port and the second discharge port. The drying cradle is rotatably connected to the inner wall of the housing through a rotating shaft. A hot air blower is set below the drying cradle. The top of the hot air blower has several air outlets, and the bottom of the housing and below the hot air blower has several air inlets.

[0008] The reactor further includes: a first tank, a second tank, and a third tank arranged vertically. The side walls of the second tank and the third tank each have several vent holes. A support plate with an annular through hole is installed at the bottom of the first tank. The second tank and the third tank are arranged on the support plate and are located on both sides of the annular through hole, thereby forming a first cavity between the first tank and the second tank and a second cavity between the second tank and the third tank. This second cavity, which contains the catalyst carrier and the impregnation liquid, is connected from top to bottom.

[0009] A first aeration ring is located above the support plate and at the bottom of the first cavity, and a second aeration ring is located at the bottom of the third tank. The top of the first aeration ring and the second aeration ring are provided with several air outlets. The first aeration ring and the second aeration ring are connected by a connecting pipe. Several first air-blocking rings are provided on the side of the second tank opposite to the third tank and along the length of the second tank. Several second air-blocking rings are provided on the inner wall of the third tank in the vertical direction.

[0010] The following are further improvements to the above technical solution:

[0011] 1. In the above scheme, a fixing plate is horizontally placed between the filter plate and the inner wall of the box, a liquid pump is installed on the top of the fixing plate, and a reflux pipe is provided between the top of the reactor and the liquid pump.

[0012] 2. In the above scheme, a liquid guide cone is installed at the top of the second tank.

[0013] 3. In the above scheme, one end of the reflux pipe is located inside the liquid guiding cone, and this end is spirally arranged along the inner wall of the liquid guiding cone.

[0014] 4. In the above scheme, a top cover with a feed pipe is installed on the top of the liquid guiding cone.

[0015] 5. In the above scheme, an arc-shaped protective plate is provided on the right side of the drying cradle.

[0016] 6. In the above scheme, a fixing sleeve is installed on the outer wall of the tank, and a number of fixing rods are provided at the bottom of the fixing sleeve.

[0017] 7. In the above scheme, a diversion cap is installed at the top of the third tank.

[0018] 8. In the above scheme, a guide plate is provided below the first discharge port.

[0019] 9. In the above scheme, the ventilation strips are spaced apart.

[0020] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0021] 1. The particulate carrier processing device of the present invention comprises a filter plate arranged at an incline inside the housing, located below a star-shaped unloader. A drying cradle with ventilation strips is positioned between the first and second discharge ports. A hot air blower is positioned below the drying cradle, with several air outlets at its top. The solid-liquid mixture of catalyst carrier and impregnation liquid is separated from the impregnation liquid by passing through the filter plate. The catalyst surface wettability is significantly reduced as the catalyst rolls on the filter plate. The catalyst enters the drying cradle with ventilation strips through the second discharge port. The hot air blown by the hot air blower dries the catalyst carrier within the drying cradle, improving the uniformity of hot air drying of the catalyst carrier, enhancing the continuity of the catalyst processing, and saving time for catalyst settling and draining, thereby improving overall processing efficiency. Furthermore, its location... The side walls of the second and third tanks inside the first tank have several vent holes. Several first air-blocking rings are arranged on the side of the second tank opposite to the third tank and along the length of the second tank. Several second air-blocking rings are arranged vertically on the inner wall of the third tank. The first and second air-blocking rings generate dense small bubbles inside the first and third tanks. Under the obstruction of the first and second air-blocking rings, the small bubbles enter the second chamber containing the catalyst carrier and impregnation liquid. This allows dense small bubbles to emerge simultaneously from both the inner and outer sides of the second chamber and rise in the second chamber. This also reduces the adhesion of the catalyst carrier to the inner wall of the tank during the impregnation process and facilitates the mixing of the catalyst carrier and the impregnation liquid, improving the thoroughness of the mixing and thus increasing the yield of the catalyst carrier.

[0022] 2. In the particulate carrier processing device of the present invention, a fixed plate is horizontally placed between the filter plate and the inner wall of the box. A liquid pump is installed on the top of the fixed plate. A return pipe is set between the top of the reactor and the liquid pump. The catalyst carrier rolls along the inclined filter plate, and the impregnation liquid falls into the box through the through hole on the filter plate. The separation of the catalyst carrier and the impregnation liquid realizes the recovery of the impregnation liquid. Then, the liquid in the box is pumped back into the reactor by the liquid pump, thereby realizing the recycling of the impregnation liquid, greatly saving the amount of impregnation liquid used, and improving the utilization efficiency of the impregnation liquid.

Detailed Implementation

[0029] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0030] Example 1: A particulate carrier processing device includes: a reaction vessel 1, which is loaded with material and installed on the top of a box 2. A through hole 201 for receiving the material in the reaction vessel 1 is opened on the top wall of the box 2, and a first discharge port 202 is opened on the side wall. The material is a solid-liquid mixture of catalyst carrier and impregnation liquid. A star-shaped unloader 3 is disposed between the reaction vessel 1 and the box 2. The upper end of the star-shaped unloader 3 is connected to the reaction vessel 1, and the lower end is connected to the through hole 201.

[0031] A filter plate 4 with filter holes 401 is provided inside the housing 2 and below the star-shaped unloader 3. The filter plate 4 is set at an incline. A partition plate 5 with a second discharge port 501 is provided between the bottom end of the filter plate 4 and the first discharge port 202.

[0032] After impregnation is completed, open the star-shaped unloader 3 so that the solid-liquid mixture of catalyst carrier and impregnation liquid enters the box 2 through the through hole 201. The solid-liquid mixture of catalyst carrier and impregnation liquid falls together onto the filter plate 4 below the star-shaped unloader 3.

[0033] Since the filter plate 4 is inclined, the catalyst carrier will roll along the filter plate 4, and the impregnation liquid will fall through the through hole 401 of the filter plate 4 and fall below the filter plate 4, thereby separating the catalyst carrier from the impregnation liquid and greatly reducing the impregnation liquid content on the surface of the catalyst carrier.

[0034] A drying cradle 6 with ventilation strips 601 is provided between the first discharge port 202 and the second discharge port 501. The drying cradle 6 is rotatably connected to the inner wall of the box 1 via a rotating shaft 7. The output shaft of a swing motor 37 is fixedly connected to the rotating shaft 7. The swing motor 37 is installed on the outer wall of the box 2. A hot air blower 8 is provided below the drying cradle 6. The top of the hot air blower 8 has several air outlets 801, and the bottom of the box 2 and below the hot air blower 8 has several air inlets 9.

[0035] The catalyst carrier falls into the drying cradle 6 through the second discharge port 501 of the partition plate 5. The outside airflow enters the box 2 through the air inlet 9, is heated by the hot air blower 8, and blows onto the drying cradle 6 to effectively dry the carrier on the drying cradle 6. The swinging drying cradle 6 can continuously output the dried carrier, and the dried catalyst carrier is output through the first discharge port 202 of the box.

[0036] The reactor 1 further includes: a first tank 10, a second tank 11 and a third tank 12 arranged vertically. The side walls of the second tank 10 and the third tank 12 each have a number of vent holes 13. A support plate 15 with an annular through hole 14 is installed at the bottom inside the first tank 10.

[0037] The second tank 11 and the third tank 12 are mounted on the support plate 15 and are located on both sides of the annular through hole 14, thereby forming a first cavity 16 between the first tank 10 and the second tank 11 and a second cavity 17 between the second tank 11 and the third tank 12. This second cavity 17, which contains the catalyst carrier and the impregnation liquid, is connected from top to bottom.

[0038] A first aeration ring 18 is provided above the support plate 15 and at the lower part of the first cavity 16, and a second aeration ring 19 is provided at the bottom of the third tank 5. The top of the first aeration ring 18 and the second aeration ring 19 are provided with several air outlets 20. The first aeration ring 18 and the second aeration ring 19 are connected by a connecting pipe 21. The air inlet 211 of the connecting pipe 21 is located on the outside of the first tank 3. Several first air-blocking rings 22 are provided on the side of the second tank 11 opposite to the third tank 12 and along the length of the second tank 11. Several second air-blocking rings 23 are provided on the inner wall of the third tank 12 in the vertical direction.

[0039] A fixing plate 24 is horizontally placed between the filter plate 2 and the inner wall of the box. A liquid pump 25 is installed on the top of the fixing plate 24. The suction pipe 251 of the liquid pump 25 is located below the fixing plate 24. A return pipe 26 is provided between the top of the reactor 1 and the liquid pump 25.

[0040] A liquid guide cone 27 is installed at the top of the second tank 11. A gap is left between the liquid guide cone 27 and the first tank 10 to facilitate the venting of the first tank 10.

[0041] A top cover 29 with a feed pipe 28 is installed on the top of the liquid guiding cone 27, which can effectively prevent debris from falling into the reactor 1. A gap is left between the top cover 29 and the liquid guiding cone 27 to facilitate the exhaust of the second chamber 17.

[0042] One end of the aforementioned return pipe 26 is located inside the liquid guiding cone 27, and this end is spirally arranged along the inner wall of the liquid guiding cone 27. The liquid flowing out from this end of the return pipe 19 will flow along the inner wall of the liquid guiding cone 24, thereby promoting the flow of liquid inside the tank and further improving the fullness of mixing between the catalyst carrier and the impregnation liquid.

[0043] The pump 25 draws liquid from inside the tank 2 through the suction pipe 251 and reintroduces it into the tank 1 through the return pipe 26. One end of the return pipe 19 is spirally arranged along the inner wall of the guide cone 24. The liquid flowing out of this return pipe 19 will flow along the inner wall of the guide cone 24, thereby promoting the flow of liquid inside the tank and further improving the thoroughness of mixing between the catalyst carrier and the impregnation liquid.

[0044] An arc-shaped protective plate 30 is provided on the right side of the aforementioned drying cradle 6. When the left side of the drying cradle 6 moves closer to the lowest position, the arc-shaped protective plate 30 on the right side moves upward, thereby shielding the second discharge port 501 and effectively preventing the catalyst carrier from falling into the air outlet 801 of the hot air blower 8.

[0045] A diversion cap 31 is installed at the top of the third tank 12, so that the catalyst carrier falling into the tank from the feed pipe 28 can diffuse inside the second cavity 17.

[0046] A fixing sleeve 33 is installed on the outer wall of the aforementioned tank 1. Several fixing rods 34 are provided at the bottom of the fixing sleeve 33, which improves the stability of the reactor installation.

[0047] Example 2: A particulate carrier processing device includes: a reaction vessel 1, which is loaded with material and installed on the top of a box 2. A through hole 201 for receiving the material in the reaction vessel 1 is opened on the top wall of the box 2, and a first discharge port 202 is opened on the side wall. The material is a solid-liquid mixture of catalyst carrier and impregnation liquid. A star-shaped unloader 3 is disposed between the reaction vessel 1 and the box 2. The upper end of the star-shaped unloader 3 is connected to the reaction vessel 1, and the lower end is connected to the through hole 201.

[0048] A filter plate 4 with filter holes 401 is provided inside the housing 2 and below the star-shaped unloader 3. The filter plate 4 is set at an incline. A partition plate 5 with a second discharge port 501 is provided between the bottom end of the filter plate 4 and the first discharge port 202.

[0049] The solid-liquid mixture of catalyst support and impregnation liquid is separated from the impregnation liquid by this filter plate 4. The wettability of the catalyst surface is also greatly reduced during the rolling process of the catalyst on the filter plate.

[0050] A drying cradle 6 with ventilation strips 601 is provided between the first discharge port 202 and the second discharge port 501. The drying cradle 6 is rotatably connected to the inner wall of the box 1 via a rotating shaft 7. The output shaft of a motor 37 is fixedly connected to the rotating shaft 7. The motor 37 is installed on the outer wall of the box 2. A hot air blower 8 is provided below the drying cradle 6. The top of the hot air blower 8 has several air outlets 801, and the bottom of the box 2 and below the hot air blower 8 has several air inlets 9.

[0051] The catalyst enters the drying cradle 6 with ventilation strips 601 through the second discharge port 501. The catalyst carrier located in the drying cradle is dried by hot air blown out by the hot air blower. This improves the uniformity of hot air drying of the catalyst carrier, improves the continuity of the catalyst processing, and saves the time of catalyst standing and draining, thereby improving the overall processing efficiency.

[0052] The reactor 1 further includes: a first tank 10, a second tank 11 and a third tank 12 arranged vertically. The side walls of the second tank 10 and the third tank 12 each have a number of vent holes 13. A support plate 15 with an annular through hole 14 is installed at the bottom inside the first tank 10.

[0053] The second tank 11 and the third tank 12 are mounted on the support plate 15 and are located on both sides of the annular through hole 14, thereby forming a first cavity 16 between the first tank 10 and the second tank 11 and a second cavity 17 between the second tank 11 and the third tank 12. This second cavity 17, which contains the catalyst carrier and the impregnation liquid, is connected from top to bottom.

[0054] A first aeration ring 18 is provided above the support plate 15 and below the first cavity 16, and a second aeration ring 19 is provided at the bottom of the third tank 5. The top of the first aeration ring 18 and the second aeration ring 19 are provided with several air outlets 20. The first aeration ring 18 and the second aeration ring 19 are connected by a connecting pipe 21. The air inlet 211 of the connecting pipe 21 is located on the outside of the first tank 3.

[0055] The first aeration ring 18 and the second aeration ring 19, which are connected to a high-pressure air source, continuously introduce air into the impregnation liquid through the air outlet 20.

[0056] A plurality of first air-blocking rings 22 are provided on the side of the second tank 11 opposite to the third tank 12 and along the length of the second tank 11, and a plurality of second air-blocking rings 23 are provided on the inner wall of the third tank 12 in the vertical direction.

[0057] Under the obstruction of the first annular baffle 22 and the second annular baffle 23, the dense small bubbles rising in the first cavity 16 and the third tank 12 respectively will enter the interior of the second cavity 17 through the vent holes 13 of the second tank 11 and the third tank 12. As a result, dense small bubbles appear on both the inner and outer sides of the second cavity 17. The rising of the small bubbles in the second cavity 17 also facilitates the mixing of the catalyst carrier and the impregnation liquid, effectively preventing the catalyst carrier from adhering to the inner wall of the tank during the impregnation process, and improving the fullness of the mixing between the catalyst carrier and the impregnation liquid, thereby increasing the yield of the catalyst carrier.

[0058] A fixing plate 24 is horizontally placed between the filter plate 2 and the inner wall of the box. A liquid pump 25 is installed on the top of the fixing plate 24. The suction pipe 251 of the liquid pump 25 is located below the fixing plate 24. A return pipe 26 is provided between the top of the reactor 1 and the liquid pump 25.

[0059] By separating the catalyst carrier from the impregnation liquid, the impregnation liquid can be recovered. Then, the liquid in the tank can be pumped back into the reactor 1 by the pump 25, thus realizing the recycling of the impregnation liquid, which greatly saves the amount of impregnation liquid used and improves the efficiency of impregnation liquid use.

[0060] A liquid guiding cone 27 is installed at the top of the second tank 11, and a top cover 29 with a feed pipe 28 is installed on the top of the liquid guiding cone 27, which can effectively prevent debris from falling into the reactor 1.

[0061] An arc-shaped protective plate 30 is provided on the right side of the aforementioned drying cradle 6. When the left side of the drying cradle 6 moves closer to the lowest position, the arc-shaped protective plate 30 on the right side moves upward, thereby shielding the second discharge port 501 and effectively preventing the catalyst carrier from falling into the air outlet 801 of the hot air blower 8.

[0062] The aforementioned ventilation strips 601 are spaced apart.

[0063] A guide plate 32 is provided below the first discharge port 102 to facilitate the collection of the catalyst carrier; a support frame 36 is provided between the guide plate 32 and the box body 2 to improve the stability of the guide plate 32.

[0064] A support base 35 is provided at the bottom of the aforementioned housing 2 and at the corner, which facilitates the entry of outside air into the hot air blower 8 through the air inlet 9 and also ensures the stability of the housing 2.

[0065] Working principle: During use, the catalyst carrier is added to the second tank 11 containing the impregnation liquid through the feed pipe 28. During the impregnation process of the catalyst carrier, the first aeration ring 18 and the second aeration ring 19, which are connected to a high-pressure air source, continuously introduce air into the impregnation liquid through the air outlet 20. Under the blocking effect of the first annular baffle 22 and the second annular baffle 23, the dense small bubbles rising in the first cavity 16 and the third tank 12 respectively will enter the interior of the second cavity 17 through the air vents 13 of the second tank 11 and the third tank 12. As a result, dense small bubbles appear on both the inner and outer sides of the second cavity 17. The rising of the small bubbles in the second cavity 17 is also conducive to the mixing of the catalyst carrier and the impregnation liquid, and reduces the situation of the catalyst carrier adhering to the inner wall of the tank during the impregnation process. It also improves the fullness of the mixing of the catalyst carrier and the impregnation liquid, thereby improving the yield of the catalyst carrier.

[0066] After impregnation is completed, the star-shaped unloader 3 is opened, allowing the solid-liquid mixture of catalyst carrier and impregnation liquid to enter the box 2 through the through hole 201. The solid-liquid mixture of catalyst carrier and impregnation liquid falls together onto the filter plate 4 below the star-shaped unloader 3. Since the filter plate 4 is inclined, the catalyst carrier will roll along the filter plate 4, and the impregnation liquid will fall through the through hole 401 of the filter plate 4 and fall below the filter plate 4, thus achieving the separation of catalyst carrier and impregnation liquid, and also greatly reducing the impregnation liquid content on the surface of catalyst carrier.

[0067] The pump 25 draws the liquid inside the tank 2 through the suction pipe 251 and reintroduces it into the tank 1 through the return pipe 26. One end of the return pipe 19 is spirally arranged along the inner wall of the guide cone 24. The liquid flowing out from this end of the return pipe 19 will flow along the inner wall of the guide cone 24, thereby promoting the flow of liquid inside the tank and further improving the fullness of mixing between the catalyst carrier and the impregnation liquid.

[0068] Next, the catalyst carrier falls into the drying cradle 6 through the second discharge port 501 of the partition plate 5. The outside airflow enters the box 2 through the air inlet 9, is heated by the hot air blower 8, and is blown onto the drying cradle 6 to effectively dry the carrier on the drying cradle 6. The swinging drying cradle 6 can continuously output the dried carrier, and the dried catalyst carrier is output through the first discharge port 202 of the box.

[0069] When the above-mentioned particulate carrier processing device is used, the solid-liquid mixture of the catalyst carrier and the impregnation liquid is separated from the impregnation liquid by this filter plate. During the process of the catalyst rolling on the filter plate, the wettability of the catalyst surface is greatly reduced. The catalyst enters the drying cradle with ventilation strips through the second discharge port. The hot air blown by the hot air blower dries the catalyst carrier located in the drying cradle, which improves the uniformity of hot air drying of the catalyst carrier, improves the continuity of the catalyst processing process, and saves the time of catalyst standing and draining, thereby improving the overall processing efficiency.

[0070] Furthermore, the first and second aeration rings generate dense small bubbles inside the first and third chambers. Under the obstruction of the first and second baffle rings, the small bubbles enter the second chamber containing the catalyst carrier and impregnation liquid. This allows dense small bubbles to emerge simultaneously from both the inner and outer sides of the second chamber. As the small bubbles rise within the second chamber, the adhesion of the catalyst carrier to the inner wall of the tank during impregnation is reduced. This also facilitates the mixing of the catalyst carrier and the impregnation liquid, improving the thoroughness of the mixing and thus increasing the yield of the catalyst carrier.

[0071] Furthermore, a fixed plate is horizontally placed between the filter plate and the inner wall of the tank. A liquid pump is installed on the top of the fixed plate, and a return pipe is set between the top of the reactor and the liquid pump. The catalyst carrier rolls along the inclined filter plate, and the impregnation liquid falls into the tank through the through holes on the filter plate. The separation of the catalyst carrier and the impregnation liquid realizes the recovery of the impregnation liquid. Then, the liquid in the tank is pumped back into the reactor by the liquid pump, so as to realize the recycling of the impregnation liquid, which greatly saves the amount of impregnation liquid used and improves the efficiency of impregnation liquid use.

[0072] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
