Abstract
Description
Technical Field
[0001] This application relates to the field of dry desulfurization technology, and in particular to a dry desulfurization efficiency improvement device and a desulfurization and dust removal chamber using the dry desulfurization efficiency improvement device. Background Technology
[0002] Inside the desulfurization and dust removal chamber, during the dust collection process using filter bags, dust particles adhere to the surface of the filter bags. These particles, in this state, are detached from the filter bag surface by the reverse airflow and vibration generated by pulsed compressed air, falling into the ash hopper. When the dust collection chamber seal fails, during negative pressure dust collection chamber operation, external moisture is drawn in due to the negative pressure inside the chamber. After sufficient contact with suspended particles, it adheres to the surface of the filter bags. Dust continuously accumulates on the surface of the filter bags, eventually leading to bag clogging. Bag clogging is a very important problem that needs to be solved in current baghouse dust collection processes. In practice, high-pressure pulsed air is often used to generate internal air vibration to shake off the accumulated dust on the surface of the filter bags. However, in practice, this has little effect on the lower part of the filter bags. In fact, the high-pressure pulsed air can even cause the filter bag structure to expand, creating tiny gaps that particles continuously fill. Frequent and prolonged pulsed airflow significantly shortens the service life of the filter bags and increases the frequency of replacement.
[0003] Inside the desulfurization and dust removal chamber, unreacted reagents and particles generated after the reaction in the sulfur-containing flue gas are propelled towards the filter bags by inertia. The filter bags initially act as a barrier, but as the particles accumulate, they overlap and compress each other, significantly reducing the effective surface area exposed for chemical reactions. This directly results in a lack of sufficient contact interface for subsequent chemical reactions, drastically reducing the reaction rate and overall reaction efficiency. Utility Model Content
[0004] In order to solve the problem that the high-pressure pulse air used in traditional dust removal is difficult to effectively clean the dust on the surface of the dust collector bags in the dust collector chamber, and at the same time solve the technical problem that the chemical reaction in the dust collector chamber lacks sufficient contact interface, resulting in a significant reduction in reaction rate and overall reaction efficiency, this utility model provides a dry desulfurization efficiency improvement device and a desulfurization dust collector using the dry desulfurization efficiency improvement device.
[0005] This invention provides a dry desulfurization efficiency improvement device, which is applied to dust collector bags in a desulfurization and dust removal chamber to improve the dry desulfurization efficiency. The dry desulfurization efficiency improvement device includes: a vibrating screen plate structure and a vibration source. The vibrating screen plate structure includes a vibrating plate installed inside the chamber and multiple vibrating screens fixed to the vibrating plate. The vibrating plate has multiple through holes for mounting the multiple vibrating screens. Each vibrating screen has a skeleton structure and includes multiple vertical ribs. One end of each vertical rib is fixed to the vibrating plate and is arranged in a ring around the axis of the corresponding through hole, while the other ends together form the free end of the corresponding vibrating screen. Each dust collector bag is fitted onto one of the free ends and fixed to the top of the chamber through the bag opening. The vibration source is used to vibrate the vibrating plate, driving the vibrating screens to vibrate the corresponding free ends on the outer surface of the corresponding dust collector bag.
[0006] In some embodiments, each skeleton structure also includes a ring rib, which is sleeved and fixed to a plurality of vertical ribs.
[0007] In some embodiments, multiple ribs are provided, one of which is sleeved and fixed at the free end of the corresponding vibration mesh, and the remaining ribs are evenly sleeved and fixed between the two ends of the corresponding vibration mesh.
[0008] In some embodiments, both the vertical ribs and the coil ribs are made of high-carbon spring steel.
[0009] In some embodiments, the vibrating plate structure also includes shock-absorbing pads, and the vibrating plate is fixedly connected to the top plate of the silo body through the shock-absorbing pads.
[0010] In some embodiments, internal cages are installed in the dust collector bag to perfectly fit the outside of the dust collector bag and support it, preventing the dust collector bag from sinking and deforming, which would reduce the dust removal effect.
[0011] In some embodiments, multiple damping pads are provided, and the multiple damping pads are distributed in an X-shape on the vibrating plate.
[0012] In some embodiments, the vibration source is an ultrasonic generator, which is fixedly installed on the outer wall of the chamber, and its output end passes through the inner wall of the chamber and is fixedly connected to the vibrating plate.
[0013] In some embodiments, a damping ring is installed between the vibration source and the inner wall of the chamber, and the vibration shaft of the vibration source is fitted with a damping ring.
[0014] This utility model also provides a desulfurization and dust removal chamber, which includes: a chamber body, multiple dust collection bags fixed inside the chamber body, and a dry desulfurization efficiency improvement device applied to the multiple dust collection bags. The improvement device is used to improve the dry desulfurization efficiency of the desulfurization and dust removal chamber. The dry desulfurization efficiency improvement device can be any of the aforementioned dry desulfurization efficiency improvement devices.
[0015] In some embodiments, multiple dust collector bags are arranged in an array, and corresponding multiple vibrating screens are also arranged in an array corresponding to multiple dust collector bags.
[0016] In some embodiments, a dust hopper is provided at the bottom of the hopper for collecting the removed dust.
[0017] In some embodiments, the desulfurization and dust removal chamber also includes a cage frame, one end of which is fixed to the top plate of the chamber body, and the other end extends into the dust removal bag to support the dust removal bag.
[0018] Compared with related technologies, the present invention has the following beneficial effects:
[0019] 1. When the ultrasonic generator is started, the high-frequency mechanical vibration it generates continuously acts on the vibrating plate. The excellent conductivity of the metal material allows the ultrasonic waves to be transmitted to the vibrating mesh. The vibrating mesh skeleton structure, as a key component that directly acts on the dust collector bag, consists of multiple vertical ribs arranged in a ring. These ribs evenly transmit the high-frequency vibration of the vibrating plate from top to bottom to the surface of the dust collector bag (the regular high-frequency vibration generates bending ripples perpendicular to the axis, continuously vibrating the surface of the dust collector bag). This continuous and regular vibration impact can dislodge the dust adhering to the outer surface of the dust collector bag, preventing it from accumulating and eventually causing bag clogging. This solves the problem that traditional high-pressure pulse air used in dust removal is unable to effectively clean dust deep on the outer surface of the dust collector bag, keeping the dust collector bag at its optimal working efficiency at all times, greatly extending the service life of the dust collector bag, reducing the frequency of dust collector bag replacement, and reducing dust removal costs. Moreover, the vibrating mesh skeleton structure design of this utility model allows all dust collector bags to vibrate at the same frequency and amplitude.
[0020] 2. Due to the high-frequency vibration of the vibrating screen structure, the originally relatively simple airflow trajectory becomes more complex as the sulfur-containing flue gas passes between multiple dust collector bags. Therefore, under the influence of airflow changes, the movement of baking soda and sulfide particles becomes complex and variable, and the collision frequency between particles increases exponentially. In the indirect periodic operation of the dust collection system, the high-frequency vibration of the vibrating screen dislodges particles adhering to the surface of the dust collector bags, allowing them to re-enter the airflow and participate in the desulfurization reaction, thus making the desulfurization reaction more complete and thorough. High-frequency vibration effectively breaks the attraction between particles, preventing the agglomeration of baking soda particles. This ensures that the particles maintain a small particle size and a large reaction surface area, allowing the reaction to proceed more quickly towards the product, greatly improving the efficiency and effectiveness of the entire reaction process. Simultaneously, it solves the technical problem of insufficient contact interface in the dust collection chamber, which significantly reduces the reaction rate and drastically lowers the overall reaction efficiency.

[0027] To better understand the purpose, technical solution, and advantages of this application, the application is described and illustrated below in conjunction with the accompanying drawings and embodiments.
[0028] This embodiment describes a desulfurization and dust removal chamber. The desulfurization and dust removal chamber in this embodiment employs a dry desulfurization efficiency enhancement device to improve its own dry desulfurization efficiency. Please refer to... Figure 1 The desulfurization and dust removal chamber includes a chamber body 1, multiple dust collector bags 6 fixed inside the chamber body 1, and a dry desulfurization efficiency enhancement device applied to the multiple dust collector bags to improve the efficiency of the desulfurization and dust removal chamber. The dry desulfurization efficiency enhancement device includes a vibrating screen structure and a vibration source 9. The chamber body 1 provides a space for desulfurization and dust removal. The dust collector bags 6 are used to filter and adsorb dust and solid particles (sodium bicarbonate particles that do not participate in the desulfurization reaction and solid products generated by the reaction). The vibrating screen structure can clean the dust and solid particles on the outer surface of the dust collector bags 6 when vibrating. The vibration source 9 provides the power for vibrating the vibrating screen structure.
[0029] Please see Figure 2The chamber 1 can be rectangular in shape, with inlets and outlets on both sides. The inlet diameter should be slightly larger than the outlet diameter. High-temperature sulfur-containing flue gas (approximately 260°C) generated by the coke oven is drawn into inlet 11 by a high-power main induced draft fan (1000kW) under negative pressure and transported towards the outlet along the flue gas conveying pipe. In the middle of the flue gas conveying pipe, a branch for adding desulfurizing agent (baking soda granules, i.e., NaHCO3) is provided. Under the negative pressure of an auxiliary small induced draft fan (55kW), it is drawn into chamber 1 from inlet 11 and thoroughly mixed with the high-speed flowing sulfur-containing flue gas. Inside the dust removal chamber, the high-temperature environment (260°C) provides the necessary conditions for a chemical reaction: the baking soda granules react with the sulfides in the flue gas via a sodium bicarbonate dry desulfurization reaction. The reaction equation is as follows:
[0030] NaHCO3=Na2CO 3+ H2O + CO2 decomposition reaction
[0031] Na₂CO₃ + SO₂ = Na₂SO₃ + CO₂ (Desulfurization reaction)
[0032] Na₂SO₃ + O₂ = Na₂SO₄ (oxidation reaction)
[0033] Na₂CO₃ + SO₂ + O₂ = Na₂SO₄ + 2CO₂ (Desulfurization oxidation reaction)
[0034] During the desulfurization process, the sulfur-containing flue gas also intercepts dust and solid particles (unreacted baking soda particles and solid products generated by the reaction) through the dust collector bags 6. A funnel-shaped ash hopper 10 can be installed at the bottom of the silo 1. When the vibrating screen structure vibrates, it cleans the dust and solid particles inside the dust collector bags 6. The dislodged dust and solid particles fall into the ash hopper 10 for centralized processing. The dust can be collected by conveying equipment such as screw conveyors and scraper conveyors, and then transported to a waste treatment site for further disposal.
[0035] Vibration source 9 provides power to the vibrating mesh plate structure. Specifically, vibration source 9 consists of two ultrasonic generators, which are fixedly mounted on the outer wall of the chamber 1 via sealing clamp 12 and damping ring 17. For better sealing, a tetrachloroethylene sealing gasket 18 can be added. The vibration shaft 16 of vibration source 9 passes through the inner wall of the chamber 1 and is fixedly connected to the vibrating plate 2. After the ultrasonic generator is turned on, its built-in ultrasonic transducer starts working immediately, quickly and accurately converting the input electrical signal into high-frequency mechanical vibration at the output end.
[0036] The main function of the dust collector bag 6 is to filter and adsorb dust particles in the flue gas. In this embodiment, the dust collector bag 6 is disposed inside the vibrating screen structure. When dust-laden gas or flue-laden gas enters from the flue gas inlet of the chamber 1 and flows between the dust collector bags, the dust is intercepted on the surface of the dust collector bag 6 under inertia, forming a dust layer. At the same time, unreacted baking soda particles and solid products generated by the reaction are also intercepted on the surface of the dust collector bag 6, while the clean gas is discharged through the pores between the fibers of the dust collector bag 6 and finally discharged from the flue gas outlet 13 of the chamber 1.
[0037] Please combine Figure 3 and Figure 4The vibrating screen structure includes a vibrating plate 2 installed inside the silo 1 and multiple vibrating screens 14 fixed on the vibrating plate 2, and may also include shock-absorbing pads 7. The vibrating plate 2 can be fixedly installed on the inner wall of the silo 1 (electroplated), and the vibrating plate 2 has multiple through holes 3 for installing multiple vibrating screens 14 respectively. In this embodiment, the through holes 3 can be arranged in an array on the vibrating plate 2, and the arrangement specification is 8*12. Each vibrating screen 14 is a skeleton structure, and each skeleton structure includes multiple vertical ribs 4 and ring ribs 5. One end of each of the multiple vertical ribs 4 is fixed to the vibrating plate 2 and is distributed in a ring around the hole axis of the corresponding through hole 3, and the other end together forms the free end of the corresponding vibrating screen. Each dust collector bag 6 is fitted on one of the free ends and passes through the through hole 3 and is fixed to the top plate 15 of the silo 1. The top plate 15 has multiple openings 20, and each opening 20 corresponds to a dust collector bag 6. The dust collector bag 6 is preferably coaxial with the opening 20. When the ultrasonic generator is started, the vibration energy at its output end is efficiently transmitted to the vibrating net 14 along the transmission path of the vibrating plate 2. The skeleton structure of the vibrating net 14, as a key component that directly acts on the dust collector bag 6, is composed of multiple vertical ribs 4 arranged in a ring. The desulfurization and dust removal chamber may also include a cage 8, one end of which is fixed to the top plate 15 of the chamber body 1, and the other end extends through the opening 20 into the dust collector bag 6 to support the dust collector bag 6. The cage 8 is preferably fitted into the inside of the dust collector bag 6, so as to better prevent the dust collector bag 6 from sinking and deforming, which would lead to a decrease in dust removal efficiency. At the same time, the multiple vertical ribs 4 can evenly transmit the high-frequency vibration of the vibrating plate 2 from top to bottom to the surface of the dust collector bag 6 (the bending ripples perpendicular to the axis generated under regular high-frequency vibration continuously vibrate the surface of the dust collector bag 6), thereby cleaning the dust attached to the outer surface of the dust collector bag 6. Furthermore, during this vibration process, the baking soda particles that were originally quietly attached to the outer surface of the dust collector bag 6 and had not yet reacted are continuously shaken off and re-enter the airflow to participate in the desulfurization reaction. Simultaneously, because the vibrating screen structure contains multiple rigid skeleton structures and dust collector bags 6 located inside the skeleton structures, the airflow of sulfur-containing flue gas is obstructed by the dust collector bags 6 as it passes through them. The originally relatively simple airflow trajectory becomes more complex, and this effect is further amplified by the high-frequency vibration. Therefore, the movement state between baking soda and sulfide particles becomes complex and variable under the influence of airflow changes. This significantly increases the chances of reactant molecules coming into contact and reacting, making the entire desulfurization reaction more complete and thorough, greatly improving the system's desulfurization efficiency.
[0038] In this embodiment, the length of the vertical rib 4 is less than the length of the dust collector bag 6. Specifically, the vertical rib 4 does not cover the bottom 1-meter section of the dust collector bag 6, because the reacted particles move downward into the ash hopper 10 under gravity. If the vibrating screen is too long, its high-frequency vibration will affect the quasi-stationary area near the ash hopper 10, thus affecting the collection of waste in the ash hopper 10.
[0039] To enable better high-frequency vibration of the vertical ribs 4, ring ribs 5 can be fitted and fixed onto multiple vertical ribs 4, connecting them to each other. Previously, the vibration of each vertical rib 4 required the vibration plate 2 to drive it; now, the ring ribs 5 allow vibration to be transmitted between each vertical rib 4, greatly improving vibration transmission efficiency. Multiple ring ribs can be provided. One ring rib 5 is fitted and fixed at the free end of the corresponding vibration mesh and is passivated (to prevent scratching of the dust collector bag 6 under high-frequency vibration). The remaining ring ribs 5 are evenly fitted and fixed between the two ends of the corresponding vibration mesh. Multiple ring ribs 5 evenly distributed along the vertical ribs 4 can further enhance the vibration transmission effect. Both vertical rib 4 and coil rib 5 can be made of high-carbon spring steel. The high-carbon spring steel undergoes oil quenching at 850℃ and medium-temperature tempering at 420℃, followed by vertical suspension quenching and tempering tension treatment. After the above heat treatment, the yield strength of vertical rib 4 and coil rib 5 reaches 950MPa, the elastic limit reaches 750MPa, and the damping ratio is reduced to about 0.008. They have high tensile strength and yield strength, can withstand large mechanical loads, and are not easily damaged under high-frequency mechanical vibration.
[0040] To reduce the impact of high-frequency vibration on the chamber 1 itself, the vibrating plate 2 can be fixedly connected to the top of the chamber 1 via damping pads 7. The damping pads 7 can buffer high-frequency vibration through elastic deformation. Multiple damping pads 7 can be provided; in this embodiment, nine are provided, arranged in an X-shape on the vibrating plate 2. By increasing the number of damping pads 7, the high-frequency vibration from the vibrating plate 2 is evenly dispersed, reducing the vibration caused by the chamber 1 itself. Furthermore, no vibration mesh structure is provided near the dust collection chamber.
[0041] Multiple cages 8 are inserted into the interiors of multiple dust collector bags 6. Each cage 8 is fixedly installed within a through hole 3, with its input end extending out of the top plate 15 of the chamber 1. The cages 8 support the dust collector bags 6, keeping them cylindrical and greatly ensuring the effective vibration of the mesh onto the bags. Furthermore, high-pressure airflow can be injected into the input end of the cages 8, causing the dust collector bags 6 to expand instantly, further enhancing the support provided by the cages 8. This allows the dust collector bags 6 to remain upright even under the direct impact of sulfur-containing flue gas, strengthening their efficiency in intercepting particulate matter in the dust collection chamber. Notably, the input end of the cages 8 can be configured as a Venturi tube structure (a fluid dynamics-designed pipe) with a gradually expanding and contracting internal structure. When high-pressure airflow is injected, the contracting section reduces airflow turbulence.
[0042] In summary, when the ultrasonic generator is activated, the high-frequency mechanical vibration it generates continuously acts on the vibrating plate 2. The excellent conductivity of the metal material allows the ultrasonic waves to be transmitted to the vibrating mesh 14. The skeleton structure of the vibrating mesh, as a key component that directly acts on the dust collector bag 6, consists of multiple vertical ribs 4 arranged in a ring, which can perfectly fit the outside of the dust collector bag 6. At the same time, the multiple vertical ribs 4 can evenly transmit the high-frequency vibration of the vibrating plate 2 from top to bottom to the surface of the dust collector bag 6 (the regular high-frequency vibration generates bending ripples perpendicular to the axis, continuously vibrating the surface of the dust collector bag 6). This continuous and regular vibration impact causes the dust adhering to the outer surface of the dust collector bag 6 and the solid particles condensed on the dust collector bag 6 to fall off, preventing them from continuously accumulating on the outer surface of the dust collector bag 6. This solves the problem that the high-pressure pulse air used in traditional dust removal is difficult to effectively clean the dust in the dust collector bag 6, keeping the dust collector bag at its optimal working efficiency at all times, greatly extending the service life of the dust collector bag 6, reducing the frequency of replacing the dust collector bag 6, and reducing dust removal costs.
[0043] Because the vibrating screen structure contains multiple rigid skeleton structures and dust collection bags 6 located inside the skeleton structures, the airflow of sulfur-containing flue gas is obstructed by the dust collection bags 6 as it passes through them, making the originally relatively simple airflow trajectory more complex. Therefore, under the influence of airflow changes, the movement state between baking soda and sulfide particles becomes complex and variable, with the collision frequency between particles increasing exponentially. This effect is further amplified by high-frequency vibration. During this vibration process, baking soda particles that were originally quietly attached to the surface of the dust collection bags 6 and had not yet reacted are continuously shaken off and re-enter the airflow to participate in the desulfurization reaction again, thus making the desulfurization reaction more complete and thorough. High-frequency vibration can effectively break the attraction between particles and prevent the agglomeration of baking soda particles. This ensures that the particles maintain a small particle size and a large reaction surface area, allowing the reaction to proceed more quickly towards the product, greatly improving the efficiency and effectiveness of the entire reaction process.
