Description

Technical Field

[0001] This utility model relates to the field of industrial waste gas treatment technology, specifically a treatment device for high-temperature dusty industrial waste gas. Background Technology

[0002] As is well known, the emission of high-temperature dusty exhaust gas is common in industrial production processes. These exhaust gases contain a large amount of dust, particulate matter and other impurities. If they are not effectively treated, they will not only pollute the environment, but may also affect the normal operation of subsequent production equipment.

[0003] Application number "CN202320715348.3" discloses an industrial waste gas purification device, including a machine body. When waste gas enters the machine body, it is first filtered by a filter screen in the air inlet pipe to remove dust and impurities. The filtered dust and impurities fall into the ash box through the ash outlet for unified collection. The filtered waste gas enters the combustion chamber, where gas from the gas cylinder is ejected from the gas gun to fully combust the waste gas, thereby removing combustible waste gas. By lifting the partition sealing plate, the waste gas enters the purification chamber through the gap at the bottom of the partition sealing plate. At the same time, the motor is started to drive the perforated mesh plate on the rotating rod and support rod to adsorb toxic waste gas substances in the purification chamber, accelerating its adsorption and purification efficiency. Similarly, lifting the partition sealing plate allows the gas to enter the disinfection chamber through the gap. The gas is irradiated by multiple ultraviolet lamps in the disinfection chamber for the final disinfection and sterilization step. After purification, the waste gas can be discharged into the natural environment.

[0004] Some dust-laden waste gas treatment devices in related technologies have shortcomings in the filtration stage. The filtration structures of some devices are quite complex, making it difficult to replace and maintain filter components, increasing the difficulty and labor intensity for operators. At the same time, some devices have poor sealing performance, making them prone to leakage during waste gas treatment, resulting in unfiltered waste gas being directly discharged into the environment, affecting treatment efficiency and the surrounding environment.

[0005] In addition, the large amount of heat energy contained in the waste gas is often overlooked during the treatment of high-temperature dusty waste gas. Most existing devices lack an effective heat recovery mechanism, resulting in energy waste and failing to meet the production concept of energy conservation and consumption reduction. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4This utility model relates to a treatment device for high-temperature dusty industrial waste gas, comprising an installation pipe 1, a filter box 2 mounted on the installation pipe 1, a filter hole between the interior of the filter box 2 and the installation pipe 1, a recovery pipe 3 on one side of the filter box 2, the recovery pipe 3 passing through the filter hole and extending to the other side of the filter box 2, a sealing groove at the top of the filter box 2, a filter groove between the sealing groove and the filter hole, a filter frame 4 on the filter groove, a filter screen layer 5 in the filter frame 4, a heat conduction mechanism between one side of the filter groove and the recovery pipe 3, and the bottom of the sealing groove... The filter frame 4 has a first inclined groove on both sides. A sealing plate 6 is provided between the filter frame 4 and the sealing groove. A bidirectional screw 7 is provided inside the sealing plate 6. Bearing seats are provided between the two ends of the bidirectional screw 7 and the inner wall of the sealing plate 6. Fastening plates 8 are provided at both ends of the bidirectional screw 7. Threaded holes are provided on the fastening plates 8, through which the bidirectional screw 7 passes. A first inclined block 9 is provided on the fastening plates 8. A turning mechanism is provided between the sealing plate 6 and the bidirectional screw 7. In this embodiment, the installation pipe 1 serves as the main channel for exhaust gas flow, and the filter hole between the filter box 2 and the installation pipe 1 allows exhaust gas to enter the filter box 2. A path is provided so that exhaust gas can flow through the filter screen layer 5 in the filter frame 4. The filter screen layer 5 intercepts and filters dust and particulate matter in the high-temperature dusty exhaust gas. The sealing plate 6 between the sealing groove and the filter frame 4 is driven by a toggle mechanism to rotate the bidirectional screw 7 and adjust the position of the fastening plate 8. The fastening plates 8 at both ends are moved by the bidirectional screw 7. The fastening plates 8 can slide linearly on the inner wall of the bidirectional screw 7 and the sealing plate 6 through the threaded holes. The first inclined block 9 on the fastening plate 8 cooperates with the first inclined groove at the bottom of the sealing groove, and the angle of inclination achieves a tight fit between the sealing plate 6 and the sealing groove, thereby ensuring the filter box. The sealing of the filter layer 2 prevents the leakage of unfiltered exhaust gas. The heat conduction mechanism is set between the filter tank and the recovery pipe 3, which can conduct the heat of the exhaust gas during the filtration process to the recovery pipe 3 to achieve preliminary heat energy recovery and waste heat recovery. When replacing the filter layer 5 later, the first inclined block 9 can be moved away from the first inclined groove by rotating the bidirectional screw 7 through the actuation mechanism. Then, the filter layer 5 can be replaced by lifting the sealing plate 6. It is convenient to use and realizes the filtration treatment of high temperature dusty exhaust gas. The filter layer 5 effectively removes impurities in the exhaust gas. Combined with the heat conduction mechanism, the recovery pipe 3 realizes the preliminary recovery of heat energy and improves the energy utilization rate.

[0027] To facilitate the rotation of the bidirectional lead screw 7, in this design, the actuating mechanism includes an adjusting shaft 10 and a gear 11. The adjusting shaft 10 is located inside the sealing plate 6 and extends to both sides of the sealing plate 6. A bearing seat is provided between the adjusting shaft 10 and the inner wall of the sealing plate 6. The gear 11 is mounted on the adjusting shaft 10 and the bidirectional lead screw 7. The two gears 11 are meshed together. When the adjusting shaft 10 is gripped and rotated, the gear 11 on it meshes with the gear 11 on the bidirectional lead screw 7, driving the bidirectional lead screw 7 to rotate. Since the threads at both ends of the bidirectional lead screw 7 are in opposite directions, and the fastening plate 8 cooperates with the bidirectional lead screw 7 through threaded holes, the rotation of the bidirectional lead screw 7 will cause the fastening plates 8 at both ends to move synchronously in opposite directions, thereby adjusting the tightness between the sealing plate 6 and the sealing groove and releasing the tightness.

[0028] The double-ended lead screw 7 (external thread) and the fastening block 8 (internal thread) form a threaded pair. When the lead screw rotates, the fastening block 8 moves bidirectionally along the lead screw axis (because the threads at both ends of the lead screw rotate in opposite directions). As required, a stable oil film (or solid lubricating film) is formed on the relatively moving surfaces in the meshing gap of the threaded pair through the retention and distribution of lubricating medium, avoiding direct metal-to-metal contact, thereby reducing the coefficient of friction and ensuring the stability of its operation.

[0029] To improve heat transfer efficiency, in this solution, the heat-conducting mechanism includes a heat-conducting plate 12 and a second inclined block 13. The heat-conducting plate 12 is located on one side of the filter tank. A heat-conducting sheet 14 is provided on the side of the heat-conducting plate 12 facing the recovery pipe 3. The heat-conducting sheet 14 abuts against the outside of the recovery pipe 3. A second inclined groove is opened at the top of the heat-conducting plate 12. The second inclined block 13 is installed on one side of the filter frame 4 and abuts against the second inclined groove. The heat-conducting sheet 14 on one side of the heat-conducting plate 12 abuts against the outside of the recovery pipe 3 to transfer heat. When the filter frame 4 is installed, the second inclined block 13 on one side of the filter frame 4 abuts against the second inclined groove at the top of the heat-conducting plate 12. As the filter frame 4 is installed in place, the second inclined block 13 exerts a squeezing force on the second inclined groove, causing the heat-conducting plate 12 to move towards the recovery pipe 3, thereby allowing the heat-conducting sheet 14 to fit more tightly against the outside of the recovery pipe 3, enhancing the heat transfer effect between the heat-conducting sheet 14 and the recovery pipe 3. The installation action of the filter frame 4 is used to optimize the contact state between the heat-conducting plate 14 and the recovery pipe 3, ensuring a tight fit between the two, significantly improving heat transfer efficiency and enhancing heat recovery. The arrangement of the heat-conducting plate 12 and the heat-conducting plate 14 allows the heat of the exhaust gas during filtration to be transferred to the recovery pipe 3 more effectively, improving energy utilization. Multiple heat-conducting plates 14 are arranged in an array, increasing the contact area with the outside of the recovery pipe 3. According to the principle of heat conduction, the larger the contact area, the more heat is transferred per unit time, thereby improving heat exchange efficiency.

[0030] To improve the filtration effect, in this solution, the filter layer 5 is provided in multiple arrays, and the multiple arrays of filter layers 5 form a multi-layer filtration structure. When the exhaust gas flows through the filter layer 5, it will be intercepted and filtered multiple times. Filter layers 5 with different pore sizes or materials can intercept particles of different sizes, increase the filtration path and filtration area, and improve the removal rate of dust and particles.

[0031] To facilitate the connection of external fixed pipelines, in this scheme, both ends of the recovery pipe 3 and the installation pipe 1 are provided with flanges 15. The flanges 15 at both ends of the recovery pipe 3 and the installation pipe 1 can be tightly connected to other pipelines or equipment through bolts and other connecting parts. The flange 15 connection has good sealing and stability, which can ensure that the gas at the pipeline connection does not leak, and at the same time facilitates installation, disassembly and maintenance.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
