Description

Technical Field

[0001] This invention belongs to the field of flue gas dust removal technology, specifically relating to a high-efficiency, self-cleaning, and anti-clogging cyclone jet bag filter. Background Technology

[0002] A cyclone dust collector is a device that uses the centrifugal force generated by a rotating airflow to separate dust from the airflow. It has a simple and compact structure, low manufacturing cost, and convenient maintenance. Because it has no moving parts or filter elements, it is particularly suitable for handling high-temperature, high-humidity, and corrosive flue gas. Cyclone dust collectors also feature low resistance loss, large air volume handling capacity, and stable performance. A baghouse dust collector, on the other hand, is a highly efficient filtration dust collection device that relies on fiber fabric filter bags to filter dust-laden gas. Its main advantage lies in its extremely high dust removal efficiency, especially its outstanding ability to capture fine dust particles.

[0003] Chinese Patent Application No. CN201910907557.6 discloses a cyclone bag filter, including a cyclone cylinder. A connecting pipe made of metal is fixed at the air outlet of the cyclone cylinder. A tank body is fixedly connected to the other end of the connecting pipe. A disc is fixed to the top of the inner cavity of the tank body. A heat insulation cover is rotatably connected to the bottom of the disc. A base plate is fixed to the bottom of the heat insulation cover. Both the disc and the base plate have two or more through holes. Two or more filter bags are arranged between the disc and the base plate. The filter bags are installed in the through holes. An air outlet pipe is provided on the side wall of the tank body. By setting up structures such as connecting pipes and heat-conducting blocks, the present invention can cool down the high-temperature gas as it flows through the connecting pipes, so that the high-temperature gas will not threaten the filter bags when passing through them, thus avoiding the burning of the filter bags.

[0004] However, traditional cyclone dust collectors experience a sharp decline in separation efficiency for fine dust particles smaller than 5μm, making it difficult to meet increasingly stringent emission standards relying solely on cyclone dust collection. Baghouse dust collectors are unsuitable for dust with high moisture content, strong adhesion, or corrosive properties. Furthermore, as operating time increases, the thickening of the dust layer on the inner wall of the dust collector and the surface of the filter bags leads to a continuous increase in operating resistance, necessitating the use of pulse-jet or mechanical rapping cleaning systems to maintain operation. This not only increases energy and compressed air consumption but also results in a relatively complex structure and higher maintenance costs. In summary, while a single cyclone dust collector is heat-resistant and inexpensive, it is insufficient to meet the emission requirements for fine dust; while a single baghouse dust collector is highly efficient, its operation is easily affected by dust collection, resulting in high operating and maintenance costs and a short filter bag lifespan; simply combining cyclone and baghouse dust collectors in series requires significant costs and greatly increases the equipment's footprint. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a highly efficient, self-cleaning, and anti-clogging cyclone jet baghouse dust collector. Through the coordination of a cyclone box, conical box, inner lining box, bag box, and dust removal and anti-clogging components, this invention achieves automatic online, real-time anti-clogging cleaning of the dust collector, and automatically performs dust removal through the flow of flue gas, saving energy and maintenance costs. Furthermore, this invention implements a dual dust removal mechanism, extending the lifespan of the filter bags; and it also features structural integration and high space utilization.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-efficiency, self-cleaning, and anti-clogging cyclone jet-type bag filter dust collector includes a cyclone box. The bottom of the cyclone box is fixedly connected to the top of the conical box. An inner liner box is housed within the inner cavities of the cyclone box and the conical box. The top of the inner liner box is fixedly connected to the top of the cyclone box and the bottom of the bag filter box. Multiple filter bags are arranged along the height direction inside the bag filter box. The inner cavities of the cyclone box and the conical box are connected. A cyclone inlet is fixedly connected to the bottom of the inner liner box. The inner cavity of the conical box is connected to the inner cavity of the inner liner box through the cyclone inlet. The inner cavity of the inner liner box is connected to the inner cavity of the bag filter box. The side of the cyclone box is connected to an inlet pipe through an air inlet, and the top of the bag filter box is connected to an outlet pipe through an air outlet. The cyclone chamber contains multiple dust-proof and anti-clogging components. One end of each component is fixedly connected to the inner wall of the cyclone chamber, and the other end is fixedly connected to the outer wall of the inner lining chamber. The dust-proof and anti-clogging components are configured such that when airflow enters the cyclone chamber, the hammer of the component will strike the inner lining chamber.

[0007] Furthermore, the dust removal and anti-clogging component includes an installation strip, the two ends of which are fixedly connected to the inner wall of the cyclone box and the outer wall of the inner liner box, respectively. A sliding groove is opened in the middle of the installation strip and a slider is slidably connected thereto. A rotating rod is rotatably connected to the slider, and a hammer is fixedly connected to both ends of the rotating rod.

[0008] Furthermore, a spring is housed in the groove of the mounting strip, with one end of the spring fixedly connected to the slider and the other end of the spring fixedly connected to the side of the mounting strip near the cyclone box.

[0009] Furthermore, a roller is rotatably connected to the side of the hammer away from the rotating rod.

[0010] Furthermore, there are eight dust-proof and anti-clogging components, which are arranged circumferentially around the cyclone inlet on the outer periphery of the inner liner box.

[0011] Furthermore, the bottom of the conical box has a dust collection port, and a dust collection box is fixedly connected to the bottom of the dust collection port. The inner cavity of the dust collection box is connected to the inner cavity of the conical box.

[0012] Furthermore, an air-guiding cone is fixedly connected to the dust collection port, with the air-guiding cone facing upwards and directly opposite the cyclone inlet.

[0013] Furthermore, the cross-section of the inner liner box gradually decreases from top to bottom, and the top of the inner liner box separates the inner cavity of the conical box from the inner cavity of the cloth bag box.

[0014] Furthermore, the dust filter bags are five in number, and the five dust filter bags are arranged at equal intervals from bottom to top in the inner cavity of the bag box, dividing the inner cavity of the bag box into six spaces.

[0015] Furthermore, the cyclone box includes four pillars, which are fixedly connected to the four corners of the bottom of the cyclone box body, and the four pillars surround the cyclone box and the conical box.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) It has a dust removal and anti-clogging component for striking the outer wall of the inner liner box to achieve the dust removal effect. The dust removal and anti-clogging component is automatically driven by the dust-laden flue gas blown in, realizing mechanical self-cleaning and anti-clogging. Because the slider is rotatably connected to the rotating rod, and two large-section head hammers are fixedly connected to both ends of the rotating rod, when the dust-laden flue gas is blown into the cyclone box from the air inlet, the rotating rod will rotate. The rotation of the rotating rod will cause the head hammers at the end to strike the outer wall of the inner liner box. The head hammers that strike the inner liner box will continue to be pushed by the high flow of flue gas, further driving the slider to slide towards the inner wall of the cyclone box. The head hammer at one end of the rotating rod passes over the outer wall of the inner liner box, and then the head hammer at the other end of the rotating rod can continue to rotate. The spring extends, and the slider slides towards the outer wall of the inner liner box, preparing for the next strike on the inner liner box. The dust removal and anti-clogging component does not require a motor. The device can be driven by a cylinder to periodically strike the inner lining box, cleaning the dust adhering to the inner and outer walls of the inner lining box through the vibration. The inner lining box is directly fixed to the bag box containing the dust filter bags, which can also cause the bag box to vibrate, thus cleaning the dust adhering to the dust filter bags. Since the dust filter bags are arranged from bottom to top in the bag box, the shaken dust can fall directly into the dust collection port below. This invention does not require additional compressed air or electricity for pulse jet cleaning. As long as there is flue gas, the knocking dust removal action will continue, realizing automatic online, real-time anti-clogging cleaning. It is especially suitable for the self-cleaning of sticky dust on the inner and outer walls of the inner lining box. The presence of springs allows the hammer to rebound quickly after striking, forming continuous or intermittent striking and generating vibration waves.

[0017] (2) High structural integration and space utilization. By nesting the inner liner box inside the cyclone box and the conical box, the physical integration of the cyclone separator and the bag filter is realized. This "box-in-box" design breaks the traditional layout that requires pipelines to be connected in series, greatly reduces the equipment's footprint and overall volume, making the equipment structure more compact and greatly saving production costs.

[0018] (3) Dual dust removal mechanism to extend the service life of filter bags. Dust-laden gas first enters the cyclone box for centrifugal separation to process large particles. Large particles in the dust-laden gas first fall into the dust collection box at the bottom of the conical box through cyclone centrifugation. Then, guided by the induced draft cone, they enter the inner cavity of the inner lining box through the cyclone inlet and continue to enter the filter bag box. Under the filtration effect of the layers of filter bags in the filter bag box, the dust-laden gas is finely filtered to process fine dust. This graded treatment mode greatly reduces the dust concentration and particle impact force entering the filter bags, and avoids high-concentration dust directly sticking to the filter bags, thereby significantly extending the service life and maintenance cycle of the dust-laden filter bags and reducing maintenance costs.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. Of course, the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] Although the steps in this invention are arranged by reference numerals, this is not intended to limit the order of the steps. Unless the order of the steps is explicitly stated or the execution of a step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" as used herein refers to and covers any and all possible combinations of one or more of the associated listed items. Example

[0023] like Figures 1-7As shown, a high-efficiency, self-cleaning, and anti-clogging cyclone jet-type bag filter dust collector includes a cyclone box 100. The bottom of the cyclone box body 101 of the cyclone box 100 is fixedly connected to the top of the conical box body 201 of the conical box 200. An inner liner box 300 is housed in the inner cavity of the cyclone box body 101 and the inner cavity of the conical box 201. The top of the inner liner box 301 is fixedly connected to the top of the cyclone box 101 and the top of the inner liner box 301 is fixedly connected to the bottom of the bag filter box 400. Multiple dust filter bags 402 are arranged along the height direction inside the bag filter box body 401 of the bag filter box 400. The inner cavity of the cyclone box 101 is connected to the inner cavity of the conical box 201. A cyclone inlet 302 is fixedly connected to the bottom of the inner liner box 301. The inner cavity of the conical box 201 is connected to the inner cavity of the inner liner box 301 via the cyclone inlet 302. The inner cavity of the inner liner box 301 is connected to the inner cavity of the bag filter box 401. The side of the cyclone box 101 is connected to the air inlet pipe 103 via the air inlet 102. The top surface of the bag filter box 401 is connected to the air outlet pipe 404 via the air outlet 403. The cyclone box 101 contains multiple dust-proof and anti-clogging components 500. One end of each dust-proof and anti-clogging component 500 is fixedly connected to the inner wall of the cyclone box 101, and the other end is fixedly connected to the outer wall of the inner liner box 301. The dust removal and anti-clogging component 500 is configured such that when the cyclone box 101 blows in flowing air, it will cause the head hammer 504 of the dust removal and anti-clogging component 500 to strike the inner lining box 301.

[0024] In this invention, a dual dust removal mechanism is implemented to extend the life of the filter bags. High-pressure dust-laden gas first enters the cyclone box 100 for centrifugal separation to handle large particles. The large particles in the dust-laden gas first fall into the dust collection box 204 at the bottom of the conical box 200 via cyclone centrifugation, and then, guided by the induced draft cone 203, enter the inner cavity of the inner liner box 301 through the cyclone inlet 302. Here, the cyclone dust removal method is used first. Cyclone dust removal relies entirely on the rotational motion of the airflow itself. High-pressure dust-laden gas enters the cyclone box 101 from the upper air inlet 102, thus rotating at high speed along the wall, forming a downward outward vortex. The centrifugal force generated by the high-speed rotation of the airflow throws dust particles, whose density is much greater than that of the gas, towards the inner wall of the cyclone box 101. The dust particles thrown onto the inner wall of the cyclone box 101 lose their inertia and, driven by gravity and airflow, slide down the wall into the cyclone box 100. At the bottom of the dust collection box 204, the rotating and descending airflow reaches the conical induced draft cone 203, then turns upward to form an internal vortex. Finally, it is discharged upward through the center and then continues to enter the bag filter box 401 through the cyclone inlet. The high-pressure dust-laden gas rotates at high speed in the cyclone box 101 while continuously rubbing against the inner wall, converting some of the pressure energy into heat energy and dissipating it. This results in the pressure of the dust-laden gas decreasing when it reaches the induced draft cone 203. The lower-pressure dust-laden gas enters the inner liner box 300, where it is finely filtered by the layers of dust filter bags 402 in the bag filter box 401 to remove fine dust. This graded treatment mode significantly reduces the dust concentration and particle impact force entering the dust filter bags 402, preventing high-concentration dust from directly clogging the dust filter bags 402. This significantly extends the service life and maintenance cycle of the dust filter bags 402 and reduces maintenance costs.

[0025] In this invention, the structure is highly integrated and the space utilization rate is high. By nesting the inner liner box 300 inside the cyclone box 100 and the conical box 200, the physical integration of the cyclone separator and the bag filter is achieved. This "box-in-box" design breaks the traditional layout that requires pipelines to be connected in series, greatly reduces the footprint and overall volume of the equipment, makes the equipment structure more compact, and greatly saves production costs.

[0026] Furthermore, the dust removal and anti-clogging component 500 includes an installation strip 501. The two ends of the installation strip 501 are fixedly connected to the inner wall of the cyclone box 101 and the outer wall of the inner lining box 301, respectively. A sliding groove is opened in the middle of the installation strip 501 and a slider 502 is slidably connected thereto. A rotating rod 503 is rotatably connected to the slider 502, and a hammer 504 is fixedly connected to both ends of the rotating rod 503.

[0027] Furthermore, a spring 505 is accommodated in the groove of the mounting strip 501. One end of the spring 505 is fixedly connected to the slider 502, and the other end of the spring 505 is fixedly connected to the side of the mounting strip 501 near the cyclone box 101.

[0028] In this invention, a dust-removing and anti-clogging component 500 is provided for striking the outer wall of the inner liner box 300 to achieve a dust removal effect. The component 500 is automatically driven by the blown-in dust-laden flue gas, achieving mechanical self-cleaning and anti-clogging. Because the slider 502 slides in the groove in the middle of the mounting strip 501, and a rotating rod 503 is rotatably connected to the slider 502, and two large-section hammers 504 are fixedly connected to both ends of the rotating rod 503, when the dust-laden flue gas is blown into the cyclone box 101 from the air inlet 102, the rotating rod 503 rotates. The rotation of the rotating rod 503 causes the hammers 504 at its ends to strike the outer wall of the inner liner box 301, and the hammers strike the outer wall of the inner liner box 301. The hammer 504 continues to be pushed by the high-flow flue gas, further driving the slider 502 to receive a thrust along the length of the mounting strip 501 and toward the inner wall of the cyclone box 101. The spring 505 contracts, and the slider 502 slides toward the inner wall of the cyclone box 101. The hammer 504 at one end of the rotating rod 503 slides across the outer wall of the inner liner box 301, and then the hammer 504 at the other end of the rotating rod 503 can continue to rotate. The spring 505 extends, and the slider 502 slides toward the outer wall of the inner liner box 301, preparing for the next strike on the inner liner box 300. The dust removal and anti-clogging component 500 does not require a motor or cylinder drive, but directly uses the flowing flue gas blown in by the air inlet pipe 103 as power. The source drives the hammer 504 to periodically strike the inner lining box 301, cleaning the dust adhering to the inner and outer walls of the inner lining box 301 through the vibration. The inner lining box 301 is directly and fixedly connected to the bag box 401 containing the dust filter bags 402, so the vibration of the inner lining box 301 drives the vibration of the bag box 401, thus also cleaning the dust adhering to the dust filter bags 402. Since the dust filter bags 402 are arranged from bottom to top in the bag box 401, the shaken-off dust falls directly into the dust collection port 202 below. This invention does not require additional compressed air or electricity for pulse jet cleaning. The inner lining box 301 is from 4mm to 6mm. Made of stainless steel, stainless steel itself is elastic and is an excellent vibration transmission medium with high elastic modulus and good vibration transmission properties. Driven by the incoming airflow, the rotating rod 503 rotates, and the rotating hammer 504 strikes the outer wall of the stainless steel inner lining box 301. The energy of the strike can be well transmitted through the box wall to achieve the effect of vibration dust removal. As long as there is flue gas, the dust removal action will continue, realizing online and real-time anti-clogging cleaning. It is especially suitable for the self-cleaning of sticky dust on the inner and outer walls of the inner lining box 301. The presence of spring 505 allows the hammer to rebound quickly after striking, forming continuous or intermittent striking and generating vibration waves.

[0029] It is worth noting that when installing the mounting strip 501, multiple countersunk holes are first drilled on the inner wall of the cyclone box 101, one end of the mounting strip 501 is placed in the countersunk hole, and then the tilt angle of the mounting strip 501 is adjusted so that the other end of the mounting strip 501 abuts against the outer wall of the inner lining box 301. Finally, the two ends of the mounting strip 501 are fixedly connected to the inner wall of the cyclone box 101 and the outer wall of the inner lining box 301 respectively by welding.

[0030] Furthermore, a roller 506 is rotatably connected to the side of the hammer 504 away from the rotating rod 503.

[0031] In this invention, rotating the roller 506 connected to the side of the hammer 504 away from the rotating rod 503 can reduce the sliding friction when hammering the outer wall of the inner lining box 301, making the hammering action more sensitive and effectively shaking off the stubborn dust attached to the inner wall.

[0032] Furthermore, there are eight dust-proof and anti-clogging components 500, which are arranged circumferentially around the cyclone inlet 302 on the periphery of the inner liner box 301.

[0033] In this invention, because the eight dust-proof and anti-clogging components 500 are arranged circumferentially around the cyclone inlet 302, the circumferential arrangement ensures that the inner liner box 300 is subjected to uniform force around its perimeter, with no dead corners for dust removal.

[0034] Furthermore, the bottom of the conical box 201 has a dust collection port 202, and a dust collection box 204 is fixedly connected to the bottom of the dust collection port 202. The inner cavity of the dust collection box 204 is connected to the inner cavity of the conical box 201.

[0035] Furthermore, an air-guiding cone 203 is fixedly connected to the dust collection port 202, with the air-guiding cone 203 facing upwards and directly opposite the cyclone inlet 302.

[0036] In this invention, the induced draft cone 203 is positioned directly opposite the cyclone inlet 302 at the dust collection port 202. This design cleverly utilizes aerodynamic principles. The induced draft cone 203 not only guides the airflow to rotate, enhancing the cyclone effect and guiding the flue gas after preliminary dust removal into the inner lining box 301 for more refined dust removal, but more importantly, it effectively prevents the high-speed rotating airflow from directly impacting the accumulated dust in the dust collection box 204, preventing the settled dust from being re-entrained into the rising airflow, thus preventing secondary dust generation and improving dust removal efficiency. Furthermore, the cross-section of the inner liner box 300 gradually decreases from top to bottom, and the top of the inner liner box 300 separates the inner cavity of the conical box 201 from the inner cavity of the cloth bag box 401.

[0037] Furthermore, there are five dust filter bags 402, which are arranged at equal intervals from bottom to top in the inner cavity of the bag box 401, dividing the inner cavity of the bag box 401 into six spaces.

[0038] In this invention, the airflow flows from bottom to top, first contacting the bottom filter bag 402. The bottom filter bag 402 mainly intercepts larger particles, while the upper filter bags 402 handle escaped fine dust. This hierarchical design avoids all dust from accumulating on the surface of a single layer of filter bags 402, resulting in a uniform distribution of dust load along the height direction. This extends the dust holding time and cleaning cycle of the entire filtration system, as well as the airflow path and residence time in the filtration area. Furthermore, the multiple layers of filter bags 402 and their mounting frames form a natural support structure within the housing, enhancing the deformation resistance of the bag housing 401.

[0039] Furthermore, the cyclone box 100 includes four pillars 104, which are fixedly connected to the four corners of the bottom of the cyclone box body 101, and the four pillars 104 surround the cyclone box 100 and the conical box 200.

[0040] Furthermore, the cyclone box 100 includes a reinforcing strip 105, with both ends of the reinforcing strip 105 fixedly connected to two adjacent support columns 104.

[0041] Furthermore, the cyclone box 100 includes a connecting plate 106, which is fixedly connected to the top of the cyclone box body 101, and the inner wall of the connecting plate 106 is fixedly connected to the bottom outer wall of the bag box body 401.

[0042] In this invention, there are two connecting plates 106 fixedly connected to the top of the cyclone box 101. The two connecting plates 106 are symmetrically arranged along the central plane of the bag box 401. The connecting plates 106 have through holes. The bottom outer wall of the bag box 401 has screw holes corresponding to the through holes on the connecting plates 106. The connecting plates 106 are fixed to the bag box 401 by the connection of screws and screw holes, thereby realizing the fixed connection between the cyclone box 100 and the bag box 400.

[0043] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
