Description

Technical Field

[0001] The present invention relates to the technical field of gas processing, and in particular to a high-temperature gas filtering and separation device. Background Art

[0002] In the industrial production process of chemical, metallurgical and environmental protection fields, the emission and treatment of high-temperature gas is an inevitable link. High-temperature gas usually contains a large amount of particulate matter and harmful gases. Direct emission without treatment will not only pollute the environment, but also affect the safe operation of equipment. Ceramic filters have become a common means of treating high-temperature gas due to their excellent high-temperature resistance and corrosion resistance. However, there are still some key problems in the application of existing ceramic filters:

[0003] Thermal shock damage and short filter life: Ceramic materials have a low coefficient of thermal expansion and cannot adapt well to drastic changes in gas temperature. When filters are handling high-temperature gases, especially when the gas temperature changes greatly, ceramic filters are prone to cracking or breaking due to thermal stress. This thermal shock phenomenon can significantly shorten the service life of the filter and increase the frequency of equipment maintenance and replacement, thereby increasing operating costs.

[0004] Insufficient utilization of thermal energy: The thermal energy of high-temperature gas has a high energy level. According to the concept of "high quality and high use", this thermal energy should be converted into mechanical energy as much as possible for the production of power. However, in existing high-temperature gas processing systems, these high-quality thermal energies are usually not fully utilized, resulting in a large amount of energy loss. Although some technologies recover thermal energy by introducing thermal storage materials, due to the uneven layout of thermal storage materials and airflow distribution, the contact between gas and thermal storage materials is insufficient, resulting in low heat absorption and utilization, and failure to achieve maximum energy conversion efficiency.

[0005] Insufficient self-cleaning ability: Ceramic filters tend to accumulate a lot of particulate matter during use, affecting the filtering effect. The filter needs to be shut down regularly for cleaning and maintenance, which increases operating costs and affects the continuous operation of the system.

[0006] In summary, the existing high-temperature gas filtration and separation devices still have room for improvement in terms of improving heat recovery efficiency, enhancing filter durability, and improving self-cleaning capabilities. Therefore, there is an urgent need for a new type of high-temperature gas filtration and separation device that can better realize the heat recovery and conversion of high-temperature gas, increase the service life of the filter, and have an efficient self-cleaning function to meet the needs of industrial production for efficient, safe, and continuous operation.

At the same time, the walls of the inner shell, the upper insulation board and the lower insulation board are sprayed with thermal insulation coatings, such as nano-composite ceramic coatings.

[0016] A polytetrafluoroethylene lining is provided on the inner wall of the inner shell, and the outer circular walls of the upper insulation plate, the lower insulation plate and the support plate are seamlessly fitted with the polytetrafluoroethylene lining. The polytetrafluoroethylene lining has good sealing and lubricating properties, thereby reducing the friction between the upper insulation plate, the lower insulation plate and the support plate, so that the resistance of the upper insulation plate, the lower insulation plate and the support plate is small when they move, and wear can be reduced. In this way, the sealing between the upper insulation plate, the lower insulation plate and the support plate and the inner wall of the inner shell can be improved.

[0017] As the preferred technical solution:

[0018] In the high-temperature gas filtering and separation device as described above, a group of connecting columns penetrate through the upper insulation plate, the lower insulation plate and the supporting plate, and the upper insulation plate, the lower insulation plate and the supporting plate are all welded to the connecting columns.

[0019] Through the above technical solution, the upper insulation board, the lower insulation board and the supporting plate are connected to form a whole through the connecting column, and then the three can move synchronously, and the structure is reasonable.

[0020] In the high-temperature gas filtering and separation device as described above, the connecting column is a hollow structure, a guide column is inserted into the connecting column, and both ends of the guide column are welded and fixed to the inner wall of the inner shell;

[0021] A hydraulic cylinder is fixed on the outer wall of the inner shell, and the piston rod end of the hydraulic cylinder extends into the inner shell and is welded and fixed to the bottom surface of the lower insulation plate.

[0022] Through the above technical solution, the outer wall of the guide column fits with the inner wall of the connecting column, so that the connecting column will not shake when moving along the guide column, thereby ensuring the sliding accuracy.

[0023] In the high-temperature gas filtering and separating device as described above, the inner circular wall of the collar and the partition are both welded and fixed to the outer wall of the inner shell, and the bottom wall of the collar is welded and connected to the first connecting pipe and the second connecting pipe.

[0024] Through the above technical solution, the first air collecting chamber and the second air collecting chamber are made into a closed chamber by welding and fixing, and the first connecting tube and the first air knife are an integrated structure, and the second connecting tube and the second air knife are an integrated structure, so that the gas in the first air collecting chamber or the second air collecting chamber can only enter the first air knife or the second air knife through the first connecting tube or the second connecting tube.

[0025] In the high-temperature gas filtering and separation device as described above, the first air knife and the second air knife are vertically distributed, the first air knife is bolted to the outer wall of the inner shell, and the second air knife is bolted to the inner wall of the outer shell.

[0028] In the high-temperature gas filtering and separation device as described above, the ceramic filter is a hollow cylindrical structure, the top and bottom ends of the ceramic filter are both bolted with annular edging sleeves, and the edging sleeves at both ends of the ceramic filter are connected to the upper fixing ring and the lower fixing ring by bearings.

[0029] The upper fixing ring is fixed to the bottom surface of the collar by welding, and the outer circular wall of the lower fixing ring is fixed to the inner wall of the outer shell by welding with a metal rod.

[0030] A gear ring is welded and fixed to the inner circular wall of the edging sleeve at the bottom end of the ceramic filter, and the gear ring is meshedly connected with a gear. The gear bayonet is fixed to the output shaft of the motor, and the motor is fixed to the outer wall of the inner shell.

[0031] Through the above technical solution, the ceramic filter is fixed to the upper fixing ring and the lower fixing ring through the edging sleeve, and the ceramic filter can rotate axially between the upper fixing ring and the lower fixing ring. The ceramic filter can switch different parts to contact the airflow through rotation, avoiding the gas from concentrating on a certain part, thereby improving the gas treatment effect.

[0032] In the high-temperature gas filtering and separation device as described above, a first gas collecting box is welded and fixed on the inner wall of the outer shell, the first gas collecting box is open facing the ceramic filter, and the open end of the first gas collecting box is in contact with the outer wall of the ceramic filter.

[0033] The first air collecting box and the first air knife are located on the same vertical plane. The size of the first air collecting box is larger than that of the first air knife. The bottom end of the first air collecting box is welded and connected to a first air outlet pipe.

[0034] Through the above technical solution, the size of the first air collecting box refers to its length and width, and its length and width are greater than the length and width of the air flow sheet sprayed by the second air knife. An air collecting chamber is formed between the first air collecting box and the outer wall of the ceramic filter, so that the gas sprayed by the first air knife can enter the air collecting chamber after passing through the ceramic filter. In this way, the gas can be centrally processed.

[0035] In the high-temperature gas filtering and separation device as described above, a second gas collecting box is welded and fixed on the outer wall of the inner shell, and the second gas collecting box is open facing the ceramic filter, and the open end of the second gas collecting box is in contact with the inner wall of the ceramic filter.

[0037] Through the above technical solution, the size of the second air collecting box refers to its length and width, and its length and width are greater than the length and width of the air flow sheet sprayed by the second air knife. An air collecting chamber is formed between the second air collecting box and the inner wall of the ceramic filter, so that the gas sprayed by the second air knife can enter the air collecting chamber after passing through the ceramic filter.

[0039] An inclined material guide plate is welded to the inner wall of the air inlet box, and the inclined surface of the material guide plate faces the open end of the air inlet box.

[0040] Through the above technical solution, the air intake pipe enters from the bottom of the outer shell and extends into the ceramic filter, which will not hinder the rotation of the ceramic filter. The high-temperature gas to be treated enters the air intake box through the air intake pipe and enters the inner shell through the opening of the air intake box, thereby completing the subsequent adsorption treatment operation.

[0041] Compared with the prior art, the present invention has at least the following beneficial effects:

[0042] (1) Efficient heat storage and conduction performance: The present invention designs an innovative heat storage system, which forms an independent heat storage chamber through the upper insulation plate, the lower insulation plate and the support plate, and the chamber is filled with graphite particles. Graphite particles have a large specific surface area and high heat capacity. They can produce suspension and tumbling motion under the action of airflow, ensuring full contact between the gas and the graphite particles. This dynamic contact greatly improves the efficiency of heat conduction and storage, ensuring that the heat in the heat storage chamber can be evenly distributed and effectively stored. Compared with traditional heat storage methods, the use of graphite particles greatly improves the thermal energy absorption capacity of the overall system, and is particularly suitable for high-temperature gas processing environments with large temperature differences.

[0043] (2) Intelligent airflow distribution and energy-saving design: The device controls the movement of the upper insulation plate, the lower insulation plate and the support plate through a hydraulic cylinder to achieve intelligent adjustment under different gas conditions. When it is necessary to process gas with a small temperature difference, the hydraulic cylinder moves these components so that the gas does not enter the heat storage chamber, but directly enters the filter unit through the guide component. This design effectively isolates the graphite particles from unnecessary airflow, avoids ineffective heat consumption, and optimizes energy efficiency. This intelligent airflow distribution function not only reduces energy consumption, but also extends the service life of the heat storage material.

[0044] (3) High-efficiency and self-cleaning filtration system: The device adopts an innovative dual-air knife design, which realizes the inner and outer layer filtration and self-cleaning functions through the first air knife and the second air knife. The ceramic filter is a hollow cylindrical structure. The first air knife is responsible for the purge of the inner layer of airflow, and the second air knife is responsible for the outer layer of airflow. Through the self-cleaning mechanism of reverse airflow, when the airflow passes through the inner and outer layers of the ceramic filter, the dust and impurities in the filter are blown back by the airflow of the air knife, ensuring that the filter always maintains efficient operation during long-term use, reducing downtime or maintenance caused by filter blockage. This design not only improves the filtration effect, but also greatly extends the service life of the ceramic filter.

[0045] (4) Improved multi-layer filtration and gas separation performance: The ceramic filter inside the device is driven by a rotating gear and can achieve 360-degree rotational filtration, avoiding the concentration of gas in a fixed area of ​​the filter, thereby achieving uniform treatment of the gas. In addition, the first gas collection box and the second gas collection box are designed to cooperate with the air knife and the ceramic filter to effectively capture the filtered gas through the large-size gas collection box. After the gas passes through the gas collection box and enters the outlet pipe, it is further separated from the solid and gas by the cyclone separator to ensure the thoroughness and efficiency of gas treatment.

[0046] (5) Structural stability and long-life design: The upper insulation board, lower insulation board and support plate are fixed by connecting columns and guide columns. These structures can ensure synchronous movement when driven by the hydraulic cylinder, and the existence of the guide column avoids shaking during movement, greatly improving the accuracy of movement. In addition, the hollow design of the connecting column makes the entire structure lighter and stronger, reduces the wear between components during operation, and enhances the long-term stability and durability of the equipment. This design effectively improves the overall service life of the equipment and reduces the maintenance frequency and cost.

[0047] (6) Safety design to prevent overheating and damage: In order to prevent the ceramic filter from being damaged by the instantaneous temperature difference of the high-temperature gas, the equipment is equipped with a heating component to preheat the filter during the initial operation, ensuring that the temperature difference between the ceramic filter and the gas remains within a safe range and avoiding thermal shock. This design significantly improves the durability of the ceramic filter and ensures the safe operation of the equipment under high temperature conditions. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0057] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0058] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0059] See also Figure 1 , Figure 2 and Figure 3 The present invention provides a technical solution: a high-temperature gas filtering and separation device, comprising an outer shell 1, and an inner shell 2 fixed in the outer shell 1, a filter component is arranged between the outer shell 1 and the inner shell 2, a heat storage component is arranged in the inner shell 2, and the filter component and the heat storage component are connected through a guide component.

[0060] The heat storage component includes an upper insulation plate 3 and a lower insulation plate 4, and a support plate 5 located between the upper insulation plate 3 and the lower insulation plate 4, and the support plate 5 is evenly provided with diversion holes 9. The lower insulation plate 4, the support plate 5 and the inner wall of the inner shell 2 enclose an air inlet cavity 10, and the upper insulation plate 3, the support plate 5 and the inner wall of the inner shell 2 enclose a heat storage cavity 11, and a plurality of graphite particles are placed inside the heat storage cavity 11.

[0061] An air intake assembly is provided on the inner shell 2 , and the air intake assembly is communicated with the air intake cavity 10 . The filter assembly includes a ceramic filter 24 sleeved on the inner shell 2 , a first air knife 20 located inside the ceramic filter 24 , and a second air knife 21 located outside the ceramic filter 24 .

[0062] When the high-temperature gas is processed, the high-temperature gas passes through the gas component into the air inlet chamber 10, and the high-temperature gas passes through the diverter hole 9 on the support plate 5 into the heat storage chamber 11. Under the action of the diverter hole 9, the high-temperature gas can be evenly distributed in the heat storage chamber 11, and graphite particles are placed in the heat storage chamber 11. The graphite particles can form a bed covering the support plate 5. Since the density of the graphite particles is small, the weight of the graphite particles is very light. When the high-temperature gas passes through the bed formed by the graphite particles, it will blow the graphite particles upward, so that the graphite particles can be suspended upward, thereby achieving boiling and tumbling. In this way, the graphite particles can be evenly contacted with the high-temperature gas, so that the heat in the high-temperature gas can be fully absorbed, thereby improving the heat storage effect of the graphite particles.

[0063] After the high-temperature gas passes through the heat storage chamber 11, heat exchange occurs with the graphite particles, thereby reducing the temperature of the gas. At the same time, during the first operation, a heating component is also provided on the inner wall of the outer shell 1. The heating component can be an infrared heating lamp, so that the ceramic filter 24 can be preheated to avoid a large temperature difference between the ceramic filter 24 and the high-temperature gas, which may cause damage to the ceramic filter 24.

[0064] After passing through the heat storage chamber 11, the high-temperature gas is diverted to the first air knife 20 and the first air knife 20 through the guide component. The first air knife 20 and the first air knife 20 spray the high-temperature gas in the form of air flow sheets, so that the gas is concentrated and will not disperse. After the high-temperature gas passes through the ceramic filter 24, the ceramic filter 24 can filter and separate impurities and harmful substances in the gas, thereby completing the gas processing operation.

[0065] like Figure 1 and Figure 5 As shown, the guide assembly includes a collar 14 sleeved on the inner shell 2, an annular cavity is formed between the inner wall of the collar 14 and the outer wall of the inner shell 2, a group of partitions 15 are welded on the inner wall of the collar 14, the partitions 15 divide the annular cavity into a first air collecting cavity 16 and a second air collecting cavity 17, a first air outlet 12 and a second air outlet 13 are opened on the wall of the inner shell 2 at the annular cavity, the first air outlet 12 is connected to the first air collecting cavity 16, the second air outlet 13 is connected to the second air collecting cavity 17, the first air knife 20 is connected to the first air collecting cavity 16 through the first connecting pipe 18, the second air knife 21 is connected to the second air collecting cavity 17 through the second connecting pipe 19, the inner circular wall of the collar 14 and the partition 15 are welded and fixed to the outer wall of the inner shell 2, and the bottom wall of the collar 14 is welded and connected to the first connecting pipe 18 and the second connecting pipe 19.

[0066] After the gas passes through the heat storage chamber 11, part of the gas will enter the first gas collecting chamber 16 through the first gas outlet 12, and part of the gas will enter the second gas collecting chamber 17 through the second gas outlet 13. The gas in the first gas collecting chamber 16 will enter the first gas knife 20 through the first connecting pipe 18, and the gas in the second gas collecting chamber 17 will enter the second gas knife 21 through the second connecting pipe 19. In this way, the first gas knife 20 and the second gas knife 21 spray the high-temperature gas toward the ceramic filter 24, thereby completing the filtering and separation of the gas.

[0067] like Figure 1 and Figure 4 As shown, a group of connecting columns 6 penetrate the upper insulation board 3, the lower insulation board 4 and the support plate 5. The upper insulation board 3, the lower insulation board 4 and the support plate 5 are all welded to the connecting columns 6. The connecting columns 6 are hollow structures. Guide columns 7 are inserted into the connecting columns 6. The two ends of the guide columns 7 are welded and fixed to the inner wall of the inner shell 2.

[0068] A hydraulic cylinder 8 is fixed on the outer wall of the inner shell 2 , and the piston rod end of the hydraulic cylinder 8 extends into the inner shell 2 and is welded and fixed to the bottom surface of the lower insulation board 4 .

[0069] When the heat storage of the high-temperature gas is completed, if the gas with large temperature fluctuations is to be processed, the upper insulation plate 3, the lower insulation plate 4 and the support plate 5 will not move, so that the low-temperature gas still enters the heat storage chamber 11 through the air inlet chamber 10. At this time, the graphite particles will still move in suspension under the drive of the low-temperature gas, thereby improving the heat exchange efficiency between the low-temperature gas and the graphite particles, and can quickly heat the low-temperature gas. The temperature of the heated gas rises, which can avoid the adverse effect of the large gas temperature difference on the ceramic filter 24.

[0070] When the gas with smaller temperature fluctuation is subsequently processed, since the gas does not need to be heated, the hydraulic cylinder 8 is energized and operated, and the hydraulic cylinder 8 drives the lower insulation plate 4 downward. Since the upper insulation plate 3, the lower insulation plate 4 and the support plate 5 are connected as a whole through the connecting column 6, the insulation plate 3, the lower insulation plate 4 and the support plate 5 move synchronously, and the connecting column 6 will slide vertically along the guide column 7, thereby improving the movement accuracy of the upper insulation plate 3, the lower insulation plate 4 and the support plate 5.

[0071] After the upper insulation plate 3, the lower insulation plate 4 and the support plate 5 are moved, the air inlet chamber 10 and the heat storage chamber 11 are not connected to the air inlet assembly. At this time, the chamber enclosed by the surface of the upper insulation plate 3 and the inner wall of the inner shell 2 is connected to the air inlet assembly. In this way, after the gas enters the chamber, it will directly enter the first air collecting chamber 16 and the second air collecting chamber 17 through the first air outlet 12 and the second air outlet 13. In this way, the gas will not contact the graphite particles, thereby avoiding unnecessary waste of heat energy on the graphite particles.

[0072] The upper insulation plate 3, the lower insulation plate 4 and the inner shell 2 can enclose a heat storage chamber to prevent the heat on the graphite particles from being conducted away, thereby improving the heat storage effect of the graphite particles.

[0073] like Figure 1 and Figure 3 As shown, the first air knife 20 and the second air knife 21 are vertically distributed, the first air knife 20 is bolted to the outer wall of the inner shell 2, and the second air knife 21 is bolted to the inner wall of the outer shell 1, the axis of the ceramic filter 24 is perpendicular to the horizontal line, and the directions of the airflows blown out by the first air knife 20 and the second air knife 21 are consistent.

[0074] The ceramic filter 24 is a hollow cylindrical structure. The top and bottom ends of the ceramic filter 24 are both bolted with annular edging sleeves. The edging sleeves at both ends of the ceramic filter 24 are connected to the upper fixing ring 22 and the lower fixing ring 23 by bearings.

[0075] The upper fixing ring 22 is fixed to the bottom surface of the sleeve ring 14 by welding, and the outer circumferential wall of the lower fixing ring 23 is fixed to the inner wall of the outer shell 1 by welding through a metal rod.

[0076] A gear ring is welded and fixed to the inner wall of the edging sleeve at the bottom end of the ceramic filter 24 , and a gear 26 is meshedly connected to the gear ring. The gear 26 is fixed to the output shaft of the motor 25 by a bayonet, and the motor 25 is fixed to the outer wall of the inner shell 2 .

[0077] After the gas is ejected through the first air knife 20 and the second air knife 21, the gas can pass through the ceramic filter 24 for filtration and separation. During this process, the motor 25 can be powered on to drive the gear 26 thereon to rotate. The gear 26 can drive the ceramic filter 24 to rotate axially on the upper fixing ring 22 and the lower fixing ring 23 through meshing with the ring gear, so that the ceramic filter 24 can be in uniform contact with the gas.

[0078] The ceramic filter 24 is a hollow double-layer structure. After the airflow ejected by the first air knife 20 contacts the inner layer of the ceramic filter 24, the inner layer of the ceramic filter 24 can filter and separate the gas. When the filtered gas passes through the outer layer of the ceramic filter 24, the dust and impurities adsorbed on the outer layer can be blown out.

[0079] After the airflow ejected by the second air knife 21 contacts the outer layer of the ceramic filter 24, the outer layer of the ceramic filter 24 can filter and separate the gas. When the filtered gas passes through the inner layer of the ceramic filter 24, the dust and impurities adsorbed on the inner layer can be blown out.

[0080] In this way, the first air knife 20 and the second air knife 21 can backwash the ceramic filter 24 while completing the gas filtration, thereby improving the filtering effect of the ceramic filter 24.

[0081] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, a first air collecting box 27 is welded and fixed on the inner wall of the outer shell 1 . The first air collecting box 27 is open facing the ceramic filter 24 , and the open end of the first air collecting box 27 fits the outer wall of the ceramic filter 24 .

[0082] The first air collecting box 27 and the first air knife 20 are located on the same vertical plane. The size of the first air collecting box 27 is larger than that of the first air knife 20 . The bottom end of the first air collecting box 27 is welded and connected to a first air outlet pipe 29 .

[0083] A second air collecting box 28 is welded and fixed to the outer wall of the inner shell 2. The second air collecting box 28 is open on the side facing the ceramic filter 24. The open end of the second air collecting box 28 fits the inner wall of the ceramic filter 24.

[0084] The second air collecting box 28 and the second air knife 21 are located on the same vertical plane. The size of the second air collecting box 28 is larger than that of the second air knife 21 . The bottom end of the second air collecting box 28 is welded to a second air outlet pipe 30 .

[0085] After passing through the ceramic filter 24 , the gas ejected from the first gas knife 20 will enter the chamber enclosed by the first gas collecting box 27 and the ceramic filter 24 . At this time, the gas can be concentrated and enter the first gas outlet pipe 29 .

[0086] After passing through the ceramic filter 24 , the gas ejected from the second gas knife 21 will enter the chamber formed by the second gas collecting box 28 and the ceramic filter 24 . At this time, the gas can be concentrated and enter the second gas outlet pipe 30 .

[0087] One end of the first air outlet pipe 29 and the second air outlet pipe 30 are connected to the air inlet end of the cyclone separator through a tee, so that the gas can be separated into gas and solid after entering the cyclone separator.

[0088] like Figure 2 , Figure 3 and Figure 7 As shown, the air intake assembly includes an air intake box 32 welded and fixed to the inner shell 2, and an air intake pipe 31 connected to the air intake box 32. The connecting end between the air intake box 32 and the inner shell 2 is open, the air intake box 32 is a hollow structure, and the top inner wall of the air intake box 32 is evenly provided with through holes 34.

[0089] An inclined material guide plate 33 is welded to the inner wall of the air inlet box 32 , and the inclined surface of the material guide plate 33 faces the open end of the air inlet box 32 .

[0090] The gas to be treated is first introduced into the air inlet pipe 31 , then introduced into the hollow cavity in the air inlet box 32 , and finally ejected through the through hole 34 and enters into the inner shell 2 .

[0091] When the upper insulation plate 3 , the lower insulation plate 4 and the support plate 5 move downward, the graphite particles in the heat storage chamber 11 will move synchronously. When the graphite particles move to the air inlet box 32 , some of the graphite particles will enter the air inlet box 32 .

[0092] Since the graphite particles do not cover the entire heat storage chamber 11, the guide plate 33 is set so that when the empty part of the heat storage chamber 11 is aligned with the air inlet box 32, the graphite particles in the air inlet box 32 will slide into the heat storage chamber 11 through the guide plate 33, thereby preventing the graphite particles from being retained in the air inlet box 32.
