Description

Technical Field

[0001] This invention relates to the field of environmental protection technology, specifically to a waste heat sludge drying device for flue gas. Background Technology

[0002] Stainless steel pipe is a hollow, long, round steel material. The production process of stainless steel pipe includes forming, shaping, cooling, cutting, heat treatment, surface treatment, and testing. During the heat treatment annealing of stainless steel pipe, the surface of the pipe contains rolling mill oil. The high temperature will cause the rolling mill oil on the surface to evaporate, producing a large amount of oil mist and particulate matter. The flue gas generated during annealing needs to be purified by a spray tower. The pickling of the pipe surface treatment will generate acid wastewater. After the acid wastewater is purified, a large amount of sludge will be deposited. The sludge is treated by a filter press and drying equipment.

[0003] The patent application with application number CN202321752035.1 mentions "a sludge drying device". This patent utilizes a structural design that combines springs and rubber balls. The first damping block and the second damping block dissipate the working vibration energy of the sludge drying machine body through friction, preventing all the working vibration of the sludge drying machine body from being transmitted to the base, reducing the working noise of the sludge drying equipment, and thus reducing the impact of working noise on the health of operators.

[0004] However, in existing technologies, flue gas treatment and sludge drying are generally operated independently, which results in the generation of a large amount of oily wastewater and high-temperature steam during treatment. The heat in the flue gas is wasted, and at the same time, a large amount of electricity is required for the thermal drying of sludge. This increases the energy consumption and water resources for flue gas and sludge treatment, which increases both pollution and treatment input, leading to increased production costs and waste of resources.

[0054] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0055] 1. Equipped with a separate control heat exchange drying component, the system utilizes a hydraulic motor, belt drive box, rotating gear, slowing gear, internal scraper crusher, and hot flushing dehumidification tank. The internal scraper crusher and hot flushing dehumidification tank rotate in opposite directions, pushing the sludge to move and perform sludge rotation, repositioning, scraping, and crushing. The system is linked by an operating motor, operating gear, combined gear, internal auger, and concave-convex pressure rollers, working in conjunction with an external exhaust pipe and a series air supply chamber for heat exchange. A multi-pipe heat exchanger, air injection pipe, hot air intake pipe, exhaust treatment box, and humid exhaust pipe drive continuous flow and repositioning of hot and humid air. Hot air flows and contacts the sludge surface for drying, while humidity is controlled, achieving sludge drying from the outside in. The reverse flushing of sludge feeding and air intake extends the contact time between the sludge and hot air, improving drying efficiency. Continuous crushing operation enables internal and external exchange, preventing the slowdown of moisture dissipation due to outer wall solidification, effectively increasing drying speed and ensuring efficient sludge drying.

[0056] The air pressure in the low-pressure heat dissipation box and the swing drying barrel is controlled by a pressure-controlled air pump and pressure-controlled operating pipe. It works in conjunction with the exhaust pressure control pipe, pressure control electric actuator and sealing isolation cover to achieve internal and external communication and isolation. It utilizes external continuous exhaust pressure control and internal correction pressure control, and heat is conducted by the wet heat exhaust pipe and one-way heat exchange jacket. The heat is introduced from the one-way heat exchange jacket to the position of the swing drying barrel. The stirring motor, stirring crushing frame, swing motor and swing drying barrel drive the sludge and swing drying barrel to continuously change position and be heated. With low pressure environment, low temperature continuous drying and multi-position pressure control, the drying speed is controlled by the low pressure and low temperature environment. Combined with the position drying treatment and continuous impact crushing treatment, the sludge is dried steadily and slowly and the sludge small particles are dried, which improves the sludge drying effect.

[0057] By combining multiple sets of counter-rotating pressing, extrusion and impact crushing, air heat exchange, contact heat exchange, hot steam exchange and low-pressure low-temperature evaporation, the problem of waste of heat resources, increased pollution and increased energy consumption caused by the independent operation of flue gas treatment and sludge drying in the existing technology is effectively solved. By using multi-position heat exchange drying, sludge crushing and repositioning drying and low-pressure low-temperature drying, heat resources are recovered while the sludge is fully dried, reducing the difficulty and cost of subsequent treatment, thereby effectively reducing resource waste and pollutant generation, and achieving the goals of reducing production costs and protecting the environment.

[0058] 2. Equipped with a constant-speed cleaning component, the pull rod semi-circular scraper is rotated along the hollow semi-circular scraper by a correction motor. The position of the pull rod semi-circular scraper and the hollow semi-circular scraper is adjusted, changing the internal space of the multi-tube heat exchanger and controlling the airflow speed and residence time. In conjunction with the air intake operating pipe, guide fan, air intake filter box and air injection pipe, the air is dried and circulated. Heat exchange occurs between the air and flue gas at the isolation replacement box and the multi-tube heat exchanger. The reciprocating hydraulic cylinder drives the reciprocating closing plate, pull rod semi-circular scraper and hollow semi-circular scraper to continuously scrape and clean the inside of the multi-tube heat exchanger, avoiding pipe blockage caused by continuous oil mist condensation and improving the stability of heat exchange between flue gas and air.

[0059] By connecting electromagnets to magnetically attach the blocking limit plates and reversing operating rods, and using electromagnets to magnetically fix the blocking limit plates to the discharge operating box and multi-row operating frame, multiple blocking limit plates are restricted. The opening and closing motor drives the reversing operating rods and blocking limit plates to rotate, and the conveying auger pushes the sludge to move, achieving discharge control at different positions and angles. This ensures the accuracy and uniformity of the discharge alignment, preventing sludge from accumulating and hindering uniform drying, thus improving the accuracy and stability of the drying and discharge coordination.

[0060] In summary, by coordinating the separate control heat exchange drying components and the constant speed cleaning components, and through flue gas exchange, oil mist impurity removal, intake humidity control, synchronous control of discharge speed and drying speed, and the coordinated utilization of hot air and hot steam flow, the heat resources in the flue gas are fully utilized. Combined with sludge flow drying treatment, the combined treatment of flue gas deheating and slag removal and sludge dewetting and drying effectively reduces the generation of wastewater and pollutants during subsequent flue gas scrubbing, while also reducing the energy consumption of subsequent sludge drying, improving resource utilization, reducing pollutant generation, and lowering the overall production cost.

The bottom end of the inner side of the one-way heat exchange jacket 427 is connected through a drain operation pipe 523.

[0116] A speed control valve 524 is embedded at one end of the hot air intake treatment pipe 408, the wet heat exhaust pipe 420, the flue gas injection pipe 423, the external flue gas exhaust pipe 424, the pressure control operation pipe 436, the cleaning and decontamination treatment pipe 514, and the liquid discharge operation pipe 523.

[0117] To ensure stable operation of the equipment, the input terminals of the conveyor motor 502, connecting electromagnet 507, opening and closing motor 508, reciprocating hydraulic cylinder 509, correction motor 513, guide fan 518, pressure closing hydraulic cylinder 520, and speed control valve 524 are all electrically connected to the output terminal of an external controller.

[0118] The working principle and usage process of this invention are as follows: During the stainless steel pipe production process, the flue gas discharged from the annealing furnace is collected by a flue gas collection device. The sludge after dewatering by the filter press is crushed by a crushing device. At this time, the operator puts activated carbon and silica gel desiccant into the air inlet filter box 515. The hydraulic motor 405 drives the input shaft of the belt drive box 404 to rotate. The input shaft of the belt drive box 404 drives the output shaft of the belt drive box 404 to rotate. Thus, the belt drive box 404 drives the rotating gear 406 and the inner scraper crusher 407 to rotate. The rotating gear 406 meshes with the deceleration gear 403 to drive the deceleration gear 403 and the hot-burning dehumidification barrel 402 to rotate. At the same time, the belt drive box 404 drives the inner scraper crusher 407 to rotate in the opposite direction of the hot-burning dehumidification barrel 402.

[0119] Simultaneously, flue gas is injected into the multi-tube heat exchanger 422 inside the isolation and replacement box 2 via external flue gas conveying equipment and flue gas injection pipe 423. Based on the intake speed and temperature, the correction motor 513 drives the pull rod semi-circular scraper 512 to rotate along the hollow semi-circular scraper 511, adjusting the space within the multi-tube heat exchanger 422 and controlling the airflow speed and residence time. Through continuous restriction and control of the intake and exhaust speeds, and by removing heat from the flue gas through the multi-tube heat exchanger 422, external air is drawn in simultaneously with the flue gas injection via the intake operating pipe 516 and the guide fan 518. The air flows along the isolation mesh plate 517 and the intake operating pipe... The air enters the inner side of the air intake filter box 515 through the air pipe 516. After being intercepted and dried by the isolation mesh plate 517, activated carbon and desiccant, the air is injected into the inner side of the isolation replacement box 2 through the air injection pipe 425 and the guide fan 518. At this time, the low temperature air comes into contact with the high temperature multi-tube heat exchanger 422 after heat conduction, and takes away the heat from its surface, realizing the heat exchange treatment between the flue gas and the air. At this time, the air is heated and the heat of the flue gas is reduced. Due to the heat loss, some of the oil mist and some particulate matter contained in the flue gas condenses and precipitates, dripping into the chamber of the multi-tube heat exchanger 422, realizing heat exchange while removing some impurities contained in the flue gas.

[0120] During continuous heat exchange and impurity condensation, the correction motor 513 drives the pull rod semi-circular scraper 512 to rotate, so that the hollow semi-circular scraper 511 and the pull rod semi-circular scraper 512 combine to form a circular scraper. In conjunction with the reciprocating hydraulic cylinder 509, the reciprocating closing plate 510 moves to continuously scrape and clean the inside of the multi-tube heat exchanger 422. In conjunction with the cleaning treatment pipe 514 and the speed control valve 524, the impurities generated during cleaning are discharged, realizing rapid internal cleaning and ensuring the stability of continuous heat exchange operation.

[0121] Sludge is fed into the rotating hot-drying dehumidification tank 402 via external feeding equipment and sludge inlet pipe 409 along the bearing discharge rack 401. At this time, the hot-drying dehumidification tank 402 rotates continuously and slowly, which drives the sludge to rotate and move synchronously and slowly. In conjunction with the rotation of the inner scraper crusher 407, the sludge adhering to the inner wall of the hot-drying dehumidification tank 402 is scraped off. The inner scraper crusher 407 rotates in the opposite direction to the hot-drying dehumidification tank 402 to continuously turn and scrape the sludge and break it down. This achieves uniform heating of the sludge inside and out and avoids the sludge accumulation and mutual adhesion affecting the drying speed.

[0122] During the sludge turning and crushing process, hot air is accelerated by the guide fan 518 and the hot air intake treatment pipe 408 and injected into the inside of the hot flushing dehumidification tank 402. The hot air enters through a small pipe, so the speed of the hot air decreases when it enters the hot flushing dehumidification tank 402. At this time, the hot air flows slowly and comes into contact with the surface of the moist and dispersed sludge. The heat of the hot air heats the water, and with the air flow, the moisture on the surface of the sludge is converted into water vapor and carried away. At the same time, by using the opposite positions of sludge feeding and air intake, a two-way flushing treatment is achieved, which prolongs the contact time between the sludge and the hot air, thereby extending the drying distance and time. Through direct contact of hot air and the airflow driving the hot steam to be discharged, the initial drying treatment of the sludge is achieved.

[0123] Once the sludge surface is completely dried, it will not stick to the inside of the hot flushing desiccant 402. Instead, it will move along the hot flushing desiccant 402, which has a certain angle, and be discharged into the discharge operation box 501 inside the integrated treatment box 1 along the discharge position of the discharge rack 401. During the continuous drying process of the sludge, the water vapor generated by the heat exchange is discharged along the humid heat exhaust pipe 420, which controls the humidity inside the hot flushing desiccant 402. Combined with continuous and slow feeding, continuous sludge drying treatment is achieved, improving the sludge treatment speed and treatment effect.

[0124] The conveying motor 502 drives the conveying auger 503 to rotate along the discharge control box 501. The conveying auger 503 carries the surface-dried sludge along the discharge control box 501. At the same time, the operating motor 413 drives the operating gear 414 to rotate. The operating gear 414 meshes with the combined gear 412 to drive the rotation of the combined gear 412. The combined gear 412 drives the inner auger frame 410 and the concave and convex pressure roller 411 to rotate, so as to realize the synchronous operation of the feeding equipment and the sludge drying equipment.

[0125] When sludge needs to be discharged from inside the discharge operation box 501, the connecting electromagnet 507 opens and closes multiple sets of multi-row operation frames 504 according to the required discharge position. When discharge is required, the connecting electromagnet 507 magnetically combines the blocking limit plate 506 and the reversing operation rod 505. At this time, the position where discharge is not required is magnetically fixed to the blocking limit plate 506 and the discharge operation box 501 by the connecting electromagnet 507. The opening and closing motor 508 drives the reversing operation rod 505 and the blocking limit plate 506 to open the discharge operation box 501. At this time, the conveying auger 503 located at the position of the discharge operation box 501 pushes the sludge to move and fall down along the opened position, realizing accurate and slow discharge of sludge.

[0126] During sludge discharge, the guide fan 518 and the external exhaust pipe 424 inject the still-heated flue gas into the series air conveying chamber 415 inside the inner auger 410 and the concave-convex pressure roller 411. The flue gas flows inside the series air conveying chamber 415 and contacts the reverse speed limiting plate 416. When the flue gas impacts the reverse speed limiting plate 416, the inner arc surface guides the flue gas to flow towards the air inlet position, so that the flue gas entering later collides with the reverse flue gas, slowing down its flow rate and increasing its contact area, so that it can fully exchange heat. In conjunction with the air inlet impact box 418, the hot air inlet treatment pipe 408 and the guide fan 518, dry hot air is input into the sludge position inside the integrated treatment box 1, so as to realize the synchronous coordination of contact heat exchange and air heat exchange.

[0127] The sludge is continuously tumbled and moved by the forward and reverse rotation of the inner swirl rack 410 and the concave and convex toothed rollers 411, breaking up the dry part on its surface caused by dehydration and causing the moist sludge inside to be turned out. It is then heated by the rapid flow of hot air from the outside and the residual heat of the flue gas inside. At the same time, the flowing air, together with the exhaust treatment box 419 and the hot exhaust pipe 420, discharges the hot steam, reducing the internal moisture. Simultaneously, the sludge is dried and crushed by both inside and outside, achieving a sludge displacement drying process, which increases the drying speed and performs secondary drying of the sludge. During the drying process, the moisture content inside the sludge is detected by the moisture detector 417. The rotation speed of the inner swirl rack 410 and the concave and convex toothed rollers 411, as well as the feeding speed of the discharge operation box 501, are adjusted according to the moisture content to control the residence time of the sludge and ensure its drying effect.

[0128] During the crushing and drying process of the sludge by the first set of inner shrunk and evenly distributed frames 410 and the concave-convex toothed rollers 411, the sludge falls along the inner shrunk and evenly distributed frames 410 and the concave-convex toothed rollers 411 to the top of the multi-row operating frame 504. At this time, the discharge position of the blocking limit plate 506 is controlled again by the connecting electromagnet 507, and the multi-row operating frame 504 is opened again by the opening and closing motor 508, which drives the reversing operating lever 505 and the blocking limit plate 506 to discharge the sludge into the position of the second set of inner shrunk and evenly distributed frames 410 and the concave-convex toothed rollers 411. The above process is repeated. The drying process involves using the second set of internal swirl racks 410 and toothed rollers 411 to perform a third drying treatment on the sludge. During the drying process, the sludge falls to the position of the multi-row operating frame 504, and the sludge discharge speed is controlled again by connecting the electromagnet 507 and the opening and closing motor 508, so that the sludge falls from the position of the multi-row operating frame 504 down to the bottom of the integrated processing box 1, thus achieving the drying and discharge process. Through multi-segmented discharge drying and independent circulation drying, the sludge is dried in segments to ensure the drying effect.

[0129] The pressure-controlled electric actuator 434 drives the sealing isolation cover 435 to move, opening the exhaust pressure control pipe 433. The pressure-controlled air pump 426 and the pressure-controlled operation pipe 436 draw air out of the low-pressure heat dissipation box 3 and the swing drying barrel 429 to control the air pressure in the low-pressure heat dissipation box 3 and the swing drying barrel 429. When the air pressure in the swing drying barrel 429 reaches the standard, the pressure-controlled electric actuator 434 drives the sealing isolation cover 435 to fit inside the exhaust pressure control pipe 433. The discharge electric slide rail 437 drives the outward push discharge plate 438 to push the sludge along the integrated treatment box 1 to the position of the screw conveyor 421. At this time, the hot steam generated during drying is injected into the inner side of the one-way heat exchange jacket 427 by the wet heat exhaust pipe 420 and the guide fan 518. The screw conveyor 421 feeds the sludge after the third drying treatment into the inner side of the feeding combination jacket 430.

[0130] During the feeding and hot steam injection process, the stirring motor 431 drives the stirring and crushing frame 432 to rotate, and the swing motor 428 drives the swing drying barrel 429 to rotate. Hot steam enters the one-way heat exchange jacket 427 under normal pressure, and the heat of the hot steam is introduced to the position of the swing drying barrel 429. At this time, the swing drying barrel 429 is heated. Through the low pressure environment inside the swing drying barrel 429, the boiling point of water in the sludge is reduced. The sludge is heated and dried by the swing drying barrel 429 heated by hot steam. During the heat conduction process, the hot steam cools down and condenses to form condensate. The condensate is discharged through the drain operation pipe 523. The swing drying barrel 429 and the stirring and crushing frame 432 rotate in opposite directions, driving the sludge to move and continuously crush it by pounding. This achieves continuous drying of the sludge while quickly peeling off its surface after drying, thereby gradually drying the sludge thoroughly.

[0131] The dried sludge moves into the drying discharge box 522 under the rotation of the swing drying drum 429. When the dried sludge accumulates to a certain amount, the hydraulic cylinder 520 drives the closing operation plate 521 to separate from the drying discharge box 522, thereby discharging the sludge into the storage box 519 for rapid discharge and collection. During the continuous drying process of the sludge, the evaporation of water in the swing drying drum 429 causes an increase in internal air pressure. At this time, the pressure control electric actuator 434 drives the sealing isolation cover 435 to move, opening the exhaust pressure control pipe 433, and discharging the hot steam in the swing drying drum 429 into the low-pressure heat dissipation box 3 through the high-pressure environment. This achieves the discharge of hot steam while controlling the air pressure in the swing drying drum 429, achieving continuous low-pressure drying in the swing drying drum 429, and recovering the water resources and dried sludge generated during drying, thereby improving the resource recovery rate and reducing resource waste.
