Description

Technical Field

[0001] This invention relates to the field of purification and dust removal equipment, specifically an industrial gas purification and dust removal device. Background Technology

[0002] In industries such as rubber processing, chemical production, and metallurgical smelting, large quantities of industrial fumes containing carbon black, steel wire scrap, oil, and volatile harmful gases are generated during production. Direct emission of these fumes not only causes air pollution and violates environmental regulations, but also leads to the waste of recyclable resources such as carbon black and heavy oil. Furthermore, the steel wire scraps in the fumes can wear down the pipes and components of subsequent processing equipment, affecting its lifespan. Low-purity recycled carbon black also fails to meet the quality requirements for downstream recycling, limiting the maximization of resource recovery value. Existing industrial gas purification and dust removal equipment still has shortcomings in terms of impurity separation accuracy, oil-gas separation stability, equipment integration, and ease of maintenance, making it difficult to meet the comprehensive needs of industrial production for efficient purification, resource recovery, and low-consumption operation and maintenance. Therefore, developing an industrial gas purification and dust removal device with a compact structure, strong synergy, capable of achieving efficient separation of carbon black and steel wire debris, stable oil-gas separation efficiency, and automatic cleaning function has become a technical problem that needs to be solved in this field. Summary of the Invention

[0003] The purpose of this invention is to provide an industrial gas purification and dust removal device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an industrial gas purification and dust removal device, comprising a chassis, a cyclone dust collector, a cooler, and an activated carbon box. The outlet of the cyclone dust collector is connected to the inlet of the cooler via a conduit. The activated carbon box is installed on the right end of the upper surface of the chassis. The activated carbon box uses activated carbon to absorb harmful substances in the flue gas. From left to right, a collection mechanism, a drive mechanism, and an oil-gas separation mechanism are sequentially installed on the upper surface of the chassis. The top of the collection mechanism is installed at the bottom of the cyclone dust collector, and the bottom of the cooler is installed at the top of the drive mechanism. The cyclone dust collector separates carbon black from the gas through centrifugal force, and the cooler cools the flue gas.

[0005] Preferably, the purpose is to collect waste carbon black material. The collection mechanism includes a collection box installed on the left end of the upper surface of the chassis. Baffles are installed on both the left and right sides of the bottom of the inner cavity of the collection box. A first collection trough is placed in the middle of the inner cavity of the collection box for collecting carbon black. A second collection trough is placed on both the left and right sides of the inner cavity of the collection box for collecting steel wire debris. The baffles limit the first and second collection troughs. Slag scraping assemblies are installed on both the left and right sides of the top of the inner cavity of the collection box.

[0006] Preferably, the slag scraping assembly includes two telescopic rods installed at the top of the inner cavity of the collection box. Springs are sleeved on the outer wall of the telescopic rods, and a first scraper is installed at the bottom end of the telescopic rods. The first scraper is pushed downward by the spring force.

[0007] Preferably, the two telescopic rods are at different heights.

[0008] Preferably, the drive mechanism includes a drive box mounted on the upper surface of the chassis, located between the collection mechanism and the oil-gas separation mechanism. A motor is mounted at the center of the lower surface of the drive box, and a driving spur gear is mounted at the output end of the motor. A first rotating shaft is mounted on both the front and rear sides of the middle of the drive box cavity via bearings. A toothed gear and a driven spur gear are respectively mounted on the upper and lower ends of the outer wall of the first rotating shaft, and the driven spur gear meshes with the driving spur gear. When the motor drives the driving spur gear to rotate, the two toothed gears rotate in the same direction through the transmission between the driving spur gear and the driven spur gear. A moving component is inserted laterally into the outer wall of the drive box to provide the driving force for left and right movement, realize the periodic cleaning of the steel wire debris and paint separation mechanism, and achieve the purpose of equipment reuse.

[0009] Preferably, the two toothed gears are arranged in the same direction.

[0010] Preferably, the moving component includes a moving rod that is laterally inserted into the outer wall of the drive box. The moving rod has racks installed at the middle of both its front and rear sides that mesh with the toothed gear. An electromagnet is installed at the left end of the moving rod that enters the collection box. When the electromagnet is energized, it generates a magnetic field that attracts steel wire debris in the flue gas to remove impurities from the carbon black. A connecting rod is installed at the right end of the moving rod via a pin.

[0011] Preferably, the electromagnet is triangular in shape.

[0012] Preferably, the oil-gas separation mechanism includes a separation tank mounted on the upper surface of the chassis. The top of the separation tank is connected to the left side of the activated carbon box via a conduit. A downwardly inclined air inlet valve is installed on the top of the left side wall of the separation tank, and the air inlet valve is connected to the air outlet of the cooler via a conduit. An air outlet valve is installed at the bottom of the right side wall of the separation tank. When the air outlet valve is opened, the heavy oil in the separation tank is discharged. A support plate is horizontally installed on the inner wall of the separation tank. An oil-stopping cap is installed at the center of the top of the support plate. The air inlet valve sprays flue gas toward the inner wall of the separation tank, and the oil droplets bounce off onto the oil-stopping cap. The gas enters the activated carbon box through the top of the separation tank. A second rotating shaft is installed at the center of the bottom of the separation tank via a bearing. One end of a swing rod is installed at the bottom of the second rotating shaft, and the other end of the swing rod is connected to the other end of a connecting rod via a pin.

[0013] Preferably, two opposing second scrapers are installed on the top of the outer wall of the second rotating shaft, and a third scraper that contacts the outer wall of the oil-stopping cap is installed on the top of the inner side of the second scraper.

[0014] Compared with the prior art, the beneficial effects of the embodiments of the present invention are: 1. This invention uses an electric motor as a power source to drive the meshing transmission of a driving spur gear and a driven spur gear, causing two toothed gears to rotate synchronously. The toothed gears, in conjunction with the rack on the moving rod, enable the moving rod to reciprocate left and right, thereby moving the electromagnet at the left end of the moving rod in an integrated manner. During this process, the electromagnet effectively adsorbs steel wire debris mixed in with the carbon black. Simultaneously, a scraping component automatically cleans the surface of the electromagnet during movement, thoroughly removing the steel wire debris adhering to its surface. This not only enables the repeated use of the electromagnet but also efficiently separates carbon black from steel wire debris, significantly improving the purity of the recovered carbon black, avoiding the impact of steel wire debris on the quality of the carbon black, ensuring the effectiveness of carbon black as a downstream product such as rubber filler and pigment carbon black, and greatly increasing the resource recovery value of carbon black.

[0015] 2. In this invention, while the moving rod moves left and right, a linkage between the connecting rod at the right end of the moving rod and the swing arm at the bottom of the second rotating shaft in the oil-gas separation mechanism creates a linkage, driving the second rotating shaft to rotate in both clockwise and counterclockwise directions. Simultaneously, the rotation of the second rotating shaft drives the second scraper on its outer wall and the third scraper on its inner side to move as a unit. The second scraper can efficiently scrape away residual heavy oil adhering to the inner wall of the separation tank, while the third scraper can precisely clean the heavy oil adhering to the surface of the oil-stopping cap. This fundamentally solves the problem of reduced separation efficiency caused by heavy oil adhering to the walls in existing oil-gas separation equipment. It eliminates the need for frequent manual disassembly and maintenance, enabling regular automatic cleaning of the oil-gas separation equipment, effectively ensuring the smooth flow of the internal space, improving the efficiency and accuracy of oil-gas separation, ensuring that heavy oil can be fully separated and recovered, significantly improving the heavy oil recovery rate, and reducing equipment maintenance costs and operational complexity.

[0016] 3. The integrated design not only simplifies the overall structure of the device, reduces the number of parts, and lowers the manufacturing cost and operating energy consumption, but also simultaneously improves the processing efficiency of carbon black treatment and oil-gas separation, achieving efficient operation of one machine with multiple functions.

[0017] This invention employs a multi-stage treatment process involving cyclone dust removal, electromagnet impurity removal, oil-gas separation, and activated carbon adsorption to efficiently purify industrial flue gas, ensuring that emissions fully comply with national industrial waste gas emission standards and effectively reducing air pollution. Simultaneously, the efficient recovery of resources such as carbon black and heavy oil can create significant additional economic benefits for enterprises. The equipment is compact, easy to install, and suitable for industrial flue gas treatment in various fields such as rubber processing, chemical production, and metallurgical smelting, possessing strong practicality and market promotion value.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] Please see Figures 1-8In this embodiment of the invention, an industrial gas purification and dust removal device includes a chassis 1, a cyclone dust collector 2, a cooler 3, and an activated carbon box 4. The outlet of the cyclone dust collector 2 and the inlet of the cooler 3 are connected by a conduit. The activated carbon box 4 is installed on the right end of the upper surface of the chassis 1. The activated carbon box 4 uses activated carbon to absorb harmful substances in the flue gas. From left to right, a collection mechanism 5, a drive mechanism 6, and an oil-gas separation mechanism 7 are installed on the upper surface of the chassis 1. The top of the collection mechanism 5 is installed at the bottom of the cyclone dust collector 2, and the bottom of the cooler 3 is installed at the top of the drive mechanism 6. The cyclone dust collector 2 separates carbon black from gas through centrifugal force. The cooler 3 cools the flue gas, causing oil molecules to gather together, which facilitates the heavy oil collection by the oil-gas separation mechanism 7.

[0023] Furthermore, the collection mechanism 5 includes a collection box 51 installed on the left end of the upper surface of the chassis 1. Baffles 52 are installed on both the left and right sides of the bottom of the inner cavity of the collection box 51. A first collection trough 53 is placed in the middle of the inner cavity of the collection box 51 for collecting carbon black. A second collection trough 54 is placed on both the left and right sides of the inner cavity of the collection box 51 for collecting steel wire scrap. The baffles 52 limit the first collection trough 53 and the second collection trough 54. Slag scraping assemblies 55 are installed on both the left and right sides of the top of the inner cavity of the collection box 51.

[0024] Furthermore, the slag scraping assembly 55 includes two telescopic rods 551 installed at the top of the inner cavity of the collection box 51. A spring 552 is sleeved on the outer wall of the telescopic rod 551, and a first scraper 553 is installed at the bottom of the telescopic rod 551. The scraper 553 is pushed downward by the elastic force of the spring 552. The two telescopic rods 551 are at different heights, so that the first scraper 553 is kept tilted. When the first scraper 553 scrapes off the wire debris, the debris can slide down the inclined surface of the first scraper 553 into the second collection trough 54.

[0025] In this embodiment, when the drive mechanism 6 drives the moving rod 671 of the moving component 67 to reciprocate left and right, the electromagnet 673 at the left end of the moving rod 671 moves as a whole, and the electromagnet 673 contacts the lower surface of the first scraper 553 during the movement. Due to the elastic force of the spring 552, the first scraper 553 always fits tightly against the inclined surface of the electromagnet 673. As the electromagnet 673 moves, the first scraper 553 forms a scraping force on the steel wire debris adsorbed on the surface of the electromagnet 673, peeling the steel wire debris from the surface of the electromagnet 673. Since the first scraper 553 is inclined, the peeled steel wire debris slides along the inclined surface of the first scraper 553 under the action of gravity into the second collection grooves 54 on the left and right sides of the collection box 51, realizing the automatic collection of steel wire debris. At the same time, the carbon black rolling off the inclined surface of the electromagnet 673 falls into the first collection groove 53 in the middle, completing the efficient separation of carbon black and steel wire debris.

[0026] The collection mechanism 5 not only achieves the classified collection of carbon black and steel wire debris, but also completes the automatic cleaning of the electromagnet 673 through the linkage of the scraper component 55 and the drive mechanism 6. It can achieve continuous operation without manual intervention, which significantly improves the operating efficiency and maintenance convenience of the equipment, while ensuring the purity of the recovered carbon black and enhancing the value of resource recovery.

[0027] Furthermore, the drive mechanism 6 includes a drive housing 61 mounted on the upper surface of the chassis 1. The drive housing 61 is located between the collection mechanism 5 and the oil-gas separation mechanism 7. A motor 62 is mounted at the center of the lower surface of the drive housing 61. A driving spur gear 63 is mounted at the output end of the motor 62. A first rotating shaft 64 is mounted on both the front and rear sides of the middle of the inner cavity of the drive housing 61 via bearings. A toothed gear 65 and a driven spur gear 66 are respectively mounted on the upper and lower ends of the outer wall of the first rotating shaft 64. The driven spur gear 66 meshes with the driving spur gear 63. When the motor 62 drives the driving spur gear 63 to rotate, the driven spur gear 66 meshes with the driven spur gear 63. The spur gear 66 drives the two toothed gears 65 to rotate in the same direction. A moving component 67 is inserted laterally into the outer wall of the drive box 61. The two toothed gears 65 are set in the same direction, which allows the two toothed gears 65 to alternately contact the rack 672. The two toothed gears 65 drive the moving rod 671 to move in opposite directions. The drive mechanism 6 can realize multi-component linkage and bidirectional reciprocating transmission through a single motor 62. There is no need to set up independent power sources for different functions. This simplifies the device structure, reduces energy consumption, and ensures the synchronization and stability of power transmission, providing reliable power support for the efficient operation of the entire slag discharge and dust removal device.

[0028] Furthermore, the moving component 67 includes a moving rod 671 that is laterally inserted into the outer wall of the drive box 61. A rack 672 that meshes with the toothed gear 65 is installed in the middle of both the front and rear sides of the moving rod 671. An electromagnet 673 that enters the collection box 51 is installed at the left end of the moving rod 671. When the electromagnet 673 is energized, it generates a magnetic field that attracts steel wire debris in the flue gas. The electromagnet 673 is triangular in shape, and the inclined surface of the electromagnet 673 allows carbon black to roll off, thus separating the debris from the carbon black. A connecting rod 674 is installed at the right end of the moving rod 671 through a pin. The connecting rod 674 changes the direction of the force and is used to pull the oil-gas separation mechanism 7.

[0029] When the equipment is started, the motor 62 is powered on and begins to run. The output of the motor 62 drives the driving spur gear 63 to rotate. Since the driving spur gear 63 meshes with both driven spur gears 66, the rotational power of the driving spur gear 63 is synchronously transmitted to the two first rotating shafts 64, thereby driving the toothed gears 65 on the two first rotating shafts 64 to rotate in the same direction. As the toothed gears 65 rotate, their teeth alternately mesh with the racks 672 on the front and rear sides of the moving rod 671: when the teeth of the toothed gear 65 on the front side mesh with the corresponding rack 672, the moving rod 671 is driven to move to the right; when the teeth of the toothed gear 65 on the front side disengage from the rack 672 and the teeth of the toothed gear 65 on the rear side mesh with the corresponding rack 672, the moving rod 671 is driven to move to the left. This cycle is repeated to realize the reciprocating motion of the moving rod 671 along the guide hole of the drive box 61.

[0030] When the moving rod 671 moves to the left, the electromagnet 673 at its left end moves to the left synchronously within the collection box 51. The electromagnet 673, when energized, continuously attracts falling steel wire debris, while the carbon black rolls down its inclined surface into the first collection trough 53. When the moving rod 671 moves to the right, the electromagnet 673 contacts the first scraper 553 in the collection mechanism 5. Under the elastic force of the spring 552, the first scraper 553 adheres tightly to the surface of the electromagnet 673, scraping off the attracted steel wire debris. The scraped steel wire debris slides down the inclined first scraper 553 into the second collection trough 54, completing the automatic cleaning of the electromagnet 673 for repeated use.

[0031] At the same time, the reciprocating motion of the moving rod 671 is transmitted to the swing rod 77 of the oil-gas separation mechanism 7 through the connecting rod 674 at the right end, which drives the swing rod 77 to swing around the second rotating shaft 76, thereby driving the second rotating shaft 76 and the second scraper 78 and the third scraper 79 on it to rotate, realizing the self-cleaning action of the oil-gas separation mechanism 7 and ensuring the continuous and stable operation of the entire equipment.

[0032] Furthermore, the oil-gas separation mechanism 7 includes a separation tank 71 mounted on the upper surface of the chassis 1. The top of the separation tank 71 is connected to the left side of the activated carbon box 4 via a conduit. A downwardly inclined air inlet valve 72 is installed on the top of the left side wall of the separation tank 71, and the air inlet valve 72 is connected to the air outlet of the cooler 3 via a conduit. An air outlet valve 73 is installed at the bottom of the right side wall of the separation tank 71. When the air outlet valve 73 is open, the heavy oil in the separation tank 71 is discharged. A support plate 74 is horizontally installed on the inner wall of the separation tank 71. An oil-catching cap 75 is installed at the center of the top of the support plate 74. The oil-catching cap 75 catches the heavy oil, separating the heavy oil from the flue gas. The air inlet valve 72 sprays the flue gas toward the inner wall of the separation tank 71, and the oil droplets bounce off onto the oil-catching cap 75. The gas enters the activated carbon box 4 through the top of the separation tank 71 and the bottom of the separation tank 71. A second rotating shaft 76 is mounted at the center via a bearing. One end of a swing rod 77 is mounted at the bottom of the second rotating shaft 76, and the other end of the swing rod 77 is connected to the other end of the connecting rod 674 via a pin. Two opposing second scrapers 78 are mounted on the top of the outer wall of the second rotating shaft 76. A third scraper 79 is mounted on the top of the inner side of the second scraper 78, which contacts the outer wall of the oil-stopping cap 75. When the second scraper 78 rotates around the second rotating shaft 76, the second scraper 78 removes heavy oil from the inner wall of the separator tank 71, and the third scraper 79 removes heavy oil from the surface of the oil-stopping cap 75, allowing the equipment to be reused. With the linkage transmission with the drive mechanism 6, the inner wall of the separator tank and the oil-stopping cap are self-cleaning, eliminating the need for manual disassembly and maintenance. This improves the heavy oil recovery rate and extends the stable operation cycle of the equipment.

[0033] After being cooled by the cooler 3, the flue gas, carrying large oil droplets, is sprayed through the inlet valve 72 onto the inner wall of the separator 71. After hitting the inner wall, the oil droplets bounce off the conical surface of the oil-cutting cap 75, achieving initial separation between the oil droplets and the flue gas. The separated oil droplets slide down the conical surface of the oil-cutting cap 75 and the inner wall of the separator 71 to the bottom of the separator 71 for storage, while the flue gas, after being de-oiled, flows upward and enters the activated carbon box 4 through the duct at the top of the separator 71. After the activated carbon adsorbs the harmful gases, the flue gas is discharged in compliance with standards.

[0034] When the drive mechanism 6 drives the moving rod 671 to reciprocate left and right, the moving rod 671 pulls the swing rod 77 to swing around the second rotating shaft 76 through the connecting rod 674 at the right end: when the moving rod 671 moves to the right, the connecting rod 674 pulls the swing rod 77 to swing to the right, causing the second rotating shaft 76 to rotate clockwise; when the moving rod 671 moves to the left, the connecting rod 674 pushes the swing rod 77 to swing to the left, causing the second rotating shaft 76 to rotate counterclockwise, thereby realizing the clockwise and counterclockwise bidirectional rotation of the second rotating shaft 76.

[0035] When the second rotating shaft 76 rotates, it simultaneously drives the two second scrapers 78 on its outer wall to rotate as a whole. The outer edge of the second scraper 78 slides against the inner wall of the separator 71 to scrape off the heavy oil adhering to the tank wall. At the same time, the third scraper 79 on the inner side of the second scraper 78 slides against the conical surface of the oil-stopping cap 75 to scrape off the oil droplets remaining on the surface of the oil-stopping cap 75. The scraped heavy oil slides down the tank wall and the conical surface to the bottom of the separator 71. Automatic cleaning of the inner wall of the separator 71 and the oil-stopping cap 75 can be achieved without manual disassembly and cleaning, ensuring the smooth flow of the oil-gas separation channel.

[0036] Working principle: Step 1: After the flue gas enters the cyclone dust collector 2, the cyclone dust collector 2 uses the difference in centrifugal force between gas and solid to separate carbon black from the gas. The carbon black falls on the surface of the electromagnet 673, the steel wire debris is attracted by the magnetic force of the electromagnet 673, and the carbon black falls into the first collection tank 53 along the inclined surface of the electromagnet 673. Step 2: The flue gas enters the cooler 3 to cool down, which gathers the oil and gas into large particles. The gas is sprayed out through the inlet valve 72, and the oil droplets are reflected in the separator 71 to the oil cut-off cap 75. The oil cut-off cap 75 collects the heavy oil, and the heavy oil falls along the oil cut-off cap 75 and the separator 71, separating the heavy oil from the flue gas. Harmful substances in the flue gas are adsorbed by activated carbon, and the flue gas is purified before being discharged, thus achieving flue gas treatment; Step 3: When it is necessary to periodically clean the wire scrap and separation tank 71, the motor 62 drives the driving spur gear 63 to rotate. Under the transmission condition of the driving spur gear 63 and the driven spur gear 66, the two toothed gears 65 rotate clockwise simultaneously. If the toothed gear 65 on the front side is in transmission with the rack 672, the moving rod 671 moves to the right. When the toothed gear 65 on the front side is in mesh with the rack 672, and the toothed gear 65 on the rear side is in mesh with the rack 672, the moving rod 671 moves to the left, thus realizing... As the moving rod 671 moves left and right, the electromagnet 673 comes into contact with the first scraper 553 under the traction of the moving rod 671. The inclined surface of the electromagnet 673 presses the first scraper 553 upward, and the telescopic rod 551 limits the first scraper 553. The first scraper 553 scrapes off the steel wire debris on the surface of the electromagnet 673. The steel wire debris slides down the inclined surface of the first scraper 553 into the second collection tank 54. As the electromagnet 673 moves left and right, the electromagnet 673 is thoroughly cleaned, preparing it for the re-extraction of carbon black. When the moving rod 671 pulls the connecting rod 674 to move left and right, the connecting rod 674 and the swing rod 77 are linked together, causing the second rotating shaft 76 to drive the second scraper 78 to rotate clockwise and counterclockwise in both directions. The second scraper 78 scrapes off the heavy oil hanging on the inner wall of the separator tank 71, while the third scraper 79 scrapes off the heavy oil on the surface of the oil stop cap 75, clearing the heavy oil falling channel.

[0037] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should also be considered within the scope of protection of the present invention. These will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
