Description

Technical Field

[0001] This invention relates to the field of solid waste treatment technology, specifically to a waste gas absorption tower for treating construction solid waste. Background Technology

[0002] Environmental engineering construction, simply put, is the entire process of construction activities to prevent and control environmental pollution, restore the ecological environment, and ensure that pollutants are treated in compliance with standards. It involves the implementation of various environmental protection facilities and ecological restoration projects from design to construction, including installation, commissioning, and acceptance. The main construction contents include, for example, air pollution control engineering construction, installation of dust removal equipment, desulfurization and denitrification devices, VOCs exhaust gas treatment systems, oil fume purification facilities, and construction of workshop exhaust gas collection pipelines; solid waste treatment and disposal construction, construction of municipal solid waste landfills and incineration plants, construction of industrial solid waste temporary storage facilities and hazardous waste treatment facilities, and construction of facilities for the resource utilization of construction waste. In the processing of construction solid waste (such as demolition waste and renovation waste), the process typically involves crushing, screening, and conveying. These processes inevitably generate complex waste gases (mainly solid powder and gaseous waste), containing not only gaseous pollutants (such as acidic gases, alkaline gases, and volatile organic compounds) but also a large amount of solid particles (dust), forming a typical two-phase solid-gas flow waste gas. Currently, for this type of composite waste gas with coexisting solid and gas, the baghouse dust collectors commonly used in the industry can only physically trap dust particles and cannot effectively purify gaseous pollutants. Furthermore, after long-term operation, the filter bags are prone to clogging due to dust adhesion and accumulation, requiring frequent cleaning. During downtime maintenance, the dust purification efficiency gradually decreases with the duration of use, making it difficult to meet the comprehensive purification needs of complex waste gases and the stability requirements of continuous operation. Therefore, it is necessary to use a waste gas absorption tower as the core purification equipment. A waste gas absorption tower is an environmental protection device designed based on the principle of gas-liquid mass transfer. Its core function is to separate and purify pollutants through the physical or chemical interaction between a specific absorption medium and harmful components in industrial waste gas, so that the waste gas can be discharged after meeting emission standards. Its essence is to use the full contact between the gas and liquid phases in a specific structure to transfer gaseous pollutants to the liquid phase (absorbent), and then achieve the recycling of the absorbent or the harmless disposal of pollutants through subsequent treatment (such as regeneration, precipitation, neutralization, etc.). Existing waste gas absorption tower treatment methods typically follow this process: Waste gas is drawn in by an induced draft fan through a collection pipe, transported through pipelines, and then directly or after only simple primary dust removal (such as a gravity settling chamber) enters the main body of the absorption tower from the bottom or side. Inside the tower, the waste gas rises through the packing layer or spray zone, comes into contact with the absorbent liquid sprayed from top to bottom, and completes mass transfer and reaction. The purified gas is discharged after being de-liquidated by a demister. Due to the multiple sources of waste gas, the time-varying composition, and the presence of bends and diameter changes in the transport pipelines, the solid particles and gas inside the waste gas often exhibit significant stratification and uneven concentration before entering the tower. This results in the waste gas entering the main body of the absorption tower in a heterogeneous state, alternating between agglomerated dust bundles and barren gas layers. This state prevents the maximization of the contact area between the gas and liquid phases within the tower, and the absorbent liquid or packing cannot be utilized evenly and fully. A large amount of waste gas fails to make sufficient contact with the absorbent liquid, resulting in a significant reduction in the effective utilization rate of the tower, which in turn affects the overall separation and purification efficiency of the tower for building waste gas. Summary of the Invention

[0003] The purpose of this invention is to provide a waste gas absorption tower for treating construction solid waste, so as to solve the above-mentioned shortcomings in the technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a waste gas absorption tower for treating construction solid waste, comprising an absorption tower body and a long curved pipe, wherein a waste gas separation component is connected between the absorption tower body and the long curved pipe, and the waste gas separation component forces the waste gas to smoothly fill the internal cross section of the absorption tower body. The exhaust gas separation assembly includes a pre-storage box and a long straight pipe installed between the long curved pipe and the absorption tower body. The long straight pipe is corrugated. Separation frames and climbing frames are installed inside the long straight pipe. The separation frames and climbing frames together form a trumpet-shaped structure with spiral increasing characteristics. A support cylinder is installed between the long straight pipe and the climbing frame. Several separation blades are fixedly connected to the outside of the support cylinder. Each separation blade has a through hole at its top. The pre-storage box is equipped with a dispersion component, which is used to cause the exhaust gas inside the long curved pipe to be dissipated by impact inside the pre-storage box. The long straight pipe and the absorption tower body are connected by a connecting assembly, which is used to allow the separation blades to rotate along the inside of the long straight pipe.

[0005] Preferably, the dispersion component includes an inlet pipe fixedly connected between the pre-storage box and the long curved pipe, and the inlet pipe communicates with the interior of the pre-storage box and the long curved pipe. The interior of the pre-storage box is fixedly connected to a connecting plate, and the connecting plate is designed in a conical shape. The external of the connecting plate is fixedly connected to several baffles, and the interior of the pre-storage box is divided into multiple independent chambers by the baffles. One end of the pre-storage box is fixedly connected to a first servo motor, which is used to drive the connecting plate to rotate. The first servo motor and the long bend are connected by a pre-diversion component, which is used to pre-separate the exhaust gas inside the long bend.

[0006] Preferably, one end of the pre-storage box is provided with a long straight channel communicating with the inside of the long straight tube, and the pre-storage box and the long straight tube together form an L-shaped channel.

[0007] Preferably, the pre-set component includes a directional column movably connected inside the long curved pipe, an active plate is fixedly sleeved on the output end of the first servo motor, one end of the directional column extends to the outside of the long curved pipe and is fixedly connected to a driven plate, and a belt strip is connected between the driven plate and the active plate. The directional column is fixedly connected to a second stirring blade and a first stirring blade, respectively, and the second stirring blade and the first stirring blade are different in length and installation angle.

[0008] Preferably, the connecting assembly includes a stabilizing ring frame fixedly connected to the outside of the absorption tower body and a connecting ring disc fixedly connected to one end of the long straight pipe, and an adjusting bolt is connected between the connecting ring disc and the stabilizing ring frame. A receiving ring is movably connected inside the connecting ring disc, and the inside of the receiving ring is fixedly connected to the top end of the separation blade. The separating blades are stably connected to the inside of the long straight tube via a receiving ring; The stabilizer frame is internally equipped with a kinetic energy component that drives the receiving ring to rotate along the inside of the connecting ring disc.

[0009] Preferably, the kinetic energy component includes a second servo motor fixedly connected inside the stabilizing ring frame and a gear ring sleeved on the outer circumference of the receiving ring, wherein the output end of the second servo motor is fixedly connected to a gear meshing with the gear ring.

[0010] Preferably, a centering ring is fixedly connected to one end of the toothed ring, and the centering ring and the toothed ring form a T-shaped structure, with one end of the centering ring embedded inside the connecting ring disk.

[0011] Preferably, a tapered spiral guide ring is fixedly connected inside the receiving ring, and the tapered spiral guide ring has a tapered structure with spiral increasing characteristics.

[0012] The technical effects and advantages provided by the present invention in the above technical solution are as follows: 1. This invention uses a separation frame and a climbing frame to force the front end of the separation blade to suddenly expand into a trumpet-shaped diffusion section, which is conducive to the uniform distribution of waste gas. Then the separation blade cuts into the main swirling flow, and through its specific inclination angle and curved surface, it cuts, splits and reorganizes the swirling flow to destroy the gas-solid boundary layer and promote separation. As a result, the physical form of the solid-gas two-phase flow is fundamentally changed after entering the absorption tower body. The solid particles are no longer just discrete phases suspended in the gas, but form a highly dispersed and mutually permeable phase with the gas, forcing all waste gas to pass through the interior of the absorption tower body evenly. Subsequently, after the waste gas enters the absorption tower body, the initial conditions of the gas-liquid-solid three-phase contact are greatly optimized. After being evenly distributed, the airflow smoothly fills the entire cross-section of the tower, and the mass transfer resistance is significantly reduced, which improves the main absorption and reaction processes and enhances the separation efficiency of the absorption tower body for solid waste. 2. This invention separates the particle group that has passed through this path by separating blades and through holes. The particle group is then captured by the strong shear vortex group generated by the separating blades. At this time, the particles are more likely to pass through the through holes due to their pre-treated motion state, which prolongs the material movement path and makes it easier for them to have effective collisions in the micro vortex, so as to further separate them and further improve the continuity of solid waste treatment of the absorption tower body. 3. This invention uses a pre-storage box and a long straight pipe to form an L-shaped channel, ensuring that the solid and gas are separated due to inertial impact after contacting the connecting plate and baffle. It actively captures the solid and gas two-phase flow that comes from the impact and uses the fluid kinetic energy at the bend to convert it into a constrained flow with clear axial and tangential velocity components. This is used to accurately deliver the waste gas in the form of a pre-swirling tight stream to the central area of ​​the funnel-shaped inlet of the separation frame and the climbing frame, ensuring that the airflow entering the absorption tower body is stable and reliable. 4. This invention uses the conical spiral guide ring frame to axially compress and radially diffuse the incoming flow, while the rotating thread provides the airflow with a basic and adjustable rotational shear force field. Its rotational speed is synchronized with the separation blades, avoiding abrupt changes and dissipation of solid and gas at the static connection point, so that the particulate matter is always in a controlled suspension and diffusion state, laying a stable foundation for the rapid mass transfer reaction in the subsequent absorption tower body. 5. This invention uses a directional column, a first stirring blade, and a second stirring blade located at the junction of the long bend and the waste inlet pipe to rotate. This first breaks the steady flow layer, particle agglomerates, and concentration boundaries formed after the long bend is transported, allowing the solid-gas two-phase flow to return to a loose and active preparatory state. This makes the solid-gas transfer to the connecting plate more stable, and the connecting plate can effectively convert most of the gas flow energy into useful work for organizing the swirling flow, rather than being consumed to resist irregular impacts or disturbances, further improving the stability of the absorption tower body for waste treatment. 6. The present invention uses the inconsistency in length and installation angle of the first and second stirring blades outside the directional column to generate disturbances of varying intensity and temporal and spatial displacement on the passing gas-solid two-phase flow. This ensures that there are no dead zones in the disturbance and provides an extremely homogenized state for the precise guidance of the subsequent connecting plate and baffle, so that the solid-gas dispersion can be maintained for a long time, further improving the reliability of the absorption tower body in waste treatment.

[0016] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0017] This invention provides, for example Figure 1 and Figure 2 The waste gas absorption tower for treating construction solid waste shown includes an absorption tower body 1 and a long curved pipe 11. A waste gas separation component 2 is connected between the absorption tower body 1 and the long curved pipe 11, and the waste gas separation component 2 forces the waste gas to smoothly fill the internal cross section of the absorption tower body 1. The exhaust gas separation assembly 2 includes a pre-storage box 21 and a long straight pipe 22 installed between the long curved pipe 11 and the absorption tower body 1. The long straight pipe 22 is corrugated, and a separation frame 23 and a climbing frame 24 are installed inside the long straight pipe 22. The separation frame 23 and the climbing frame 24 together form a trumpet-shaped structure with a spiral increasing characteristic. A support cylinder 27 is installed between the long straight pipe 22 and the climbing frame 24. Several separation blades 25 are fixedly connected to the outside of the support cylinder 27, and each separation blade 25 has a through hole 26 at its top. The specific number of the separation blades 25 is four, and the separation blades 25 are designed with a willow leaf shape to break the large-scale vortex into multi-scale micro vortices, so as to achieve a deep and uniform separation of matter and momentum. The high local velocity gradient (strong shear force) generated by the blades can effectively strip the particle clusters and attached dust in the gas, continuously suppress the stable formation of the solid-gas boundary layer, so that the solid particles and gas reach a highly dispersed and mutually penetrating quasi-homogeneous mixing state, eliminating local concentration zones. At the same time, the four separation blades 25 are arranged in a circle around the outside of the support cylinder 27.

[0018] refer to Figure 2 and Figure 3 As shown, the pre-storage box 21 is equipped with a dispersion component 3, which is used to cause the exhaust gas inside the long bend pipe 11 to collide and dissipate inside the pre-storage box 21. The dispersion component 3 includes an exhaust pipe 31 fixedly connected between the pre-storage box 21 and the long bend pipe 11, and the exhaust pipe 31 communicates with the interior of the pre-storage box 21 and the long bend pipe 11. A connecting plate 32 is fixedly connected inside the pre-storage box 21, and the connecting plate 32 is set in a conical shape. The connecting plate 32 is externally fixedly connected to several baffles 33, and the interior of the pre-storage box 21 is divided into multiple independent chambers by the baffles 33. One end of the pre-storage box 21 is fixedly connected to a first servo motor 35, which is used to drive the connecting plate 32 to rotate. One end of the pre-storage box 21 is provided with a long straight channel 34 that communicates with the interior of the long straight pipe 22. The pre-storage box 21 and the long straight pipe 22 together form an L-shaped channel through the long straight channel 34. The inertial force is used to perform preliminary gas-solid separation and reconstruct the disordered airflow into an ordered vortex, remove some large particles in advance, reduce the subsequent load, and convert the exhaust gas into a stable and directional vortex, creating a stable initial flow state for deep treatment and improving the reliability of the air intake. refer to Figure 2 and Figure 7 As shown, a pre-separation assembly 5 is connected between the first servo motor 35 and the long bend 11. The pre-separation assembly 5 is used to pre-separate the exhaust gas inside the long bend 11. The pre-separation assembly 5 includes a directional column 51 movably connected inside the long bend 11. The output end of the first servo motor 35 is fixedly sleeved with a drive plate 56. One end of the directional column 51 extends to the outside of the long bend 11 and is fixedly connected with a driven plate 54. A belt strip 55 is connected between the driven plate 54 and the drive plate 56. The directional column 51 is fixedly connected to a second stirring blade 53 and a first stirring blade 52. The second stirring blade 53 and the first stirring blade 52 are of different lengths and installation angles. This effectively prevents the accumulation and blockage of solid materials caused by changes in flow velocity, breaks up the already formed stable flow layer and particle agglomerates, keeps the waste material in a loose and active preparatory state, and ensures that the subsequent connecting plate 32 and other components can efficiently and smoothly receive and convert fluid kinetic energy, thereby enhancing the continuity of operation. refer to Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, a connecting assembly 4 is connected between the long straight pipe 22 and the absorption tower body 1. The connecting assembly 4 is used to make the separation blade 25 rotate along the inside of the long straight pipe 22. The connecting assembly 4 includes a stabilizing ring frame 42 fixedly connected to the outside of the absorption tower body 1 and a connecting ring disk 41 fixedly connected to one end of the long straight pipe 22. An adjusting bolt 49 is connected between the connecting ring disk 41 and the stabilizing ring frame 42. A receiving ring 43 is movably connected inside the connecting ring disk 41. The inside of the receiving ring 43 is fixedly connected to the top end of the separation blade 25. The separating blade 25 is stably connected to the inside of the long straight tube 22 via the receiving ring 43; refer to Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the inside of the stabilizing ring frame 42 is equipped with a kinetic energy component that drives the receiving ring 43 to rotate along the inside of the connecting ring disk 41. The kinetic energy component includes a second servo motor 47 fixedly connected inside the stabilizing ring frame 42 and a gear ring 45 sleeved on the outer periphery of the receiving ring 43. The output end of the second servo motor 47 is fixedly connected to a gear 48 that meshes with the gear ring 45. One end of the toothed ring 45 is fixedly connected to a centering ring 46, and the centering ring 46 and the toothed ring 45 form a T-shaped structure. One end of the centering ring 46 is embedded inside the connecting ring disk 41. The receiving ring 43 is fixedly connected to a conical spiral guide ring frame 44, which has a conical structure with spiral increasing characteristics. The structure of the conical spiral guide ring frame 44 compresses the incoming flow axially and diffuses it radially, while the rotating thread gives the airflow a basic and adjustable rotational shear force field. Its rotational speed is synchronized with that of the separating blade 25, avoiding abrupt changes and dissipation of solid and gas at the static connection point, so that the particulate matter is always in a controlled suspension and diffusion state, laying a stable foundation for the rapid mass transfer reaction in the subsequent absorption tower body 1.

[0019] Working principle: When using: refer to Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, when the absorption tower body 1 needs to treat construction solid waste, firstly, the long straight pipe 22 is aligned with the stabilizing ring frame 42, and then the connecting ring plate 41 is kept in contact with the stabilizing ring frame 42. During this process, the receiving ring 43 is located between the stabilizing ring frame 42 and the connecting ring plate 41 to keep the connection between the stabilizing ring frame 42 and the connecting ring plate 41 sealed. The end of the centering ring 46 is embedded into the interior of the stabilizing ring frame 42 and the connecting ring plate 41 to further limit the toothed ring 45 in the connecting ring plate 41, so that the toothed ring 45 rotates along the internal guide of the connecting ring plate 41, ensuring the reliable transmission and isolation of rotational power in the long straight pipe 22, preventing waste gas leakage, and providing a stable mechanical basis for subsequent dynamic treatment. Secondly, one end of the long curved pipe 11 is connected to the exhaust port of the solid pulverizer to facilitate the stable delivery of exhaust gas into the inlet pipe 31. Then, the first servo motor 35 drives the connecting plate 32 to rotate synchronously along the inside of the pre-storage box 21. Next, the inlet pipe 31 delivers the exhaust gas inside to the baffle 33 sequentially. During this process, a large amount of the exhaust gas will dissipate due to impact, thus pre-separating it before it enters the pre-storage box 21 and the absorption tower body 1. Furthermore, the long straight channel 34 horizontally delivers the gas inside the pre-storage box 21 into the long straight pipe 22, and the exhaust gas inside the long straight pipe 22 is delivered to the separation frame 23. The separation frame 23 and the climbing frame 24 then initially constrain the exhaust gas, used to... The exhaust gas is treated in layers, dividing the large stream into multiple uniform small streams. As the separation frame 23 and the climbing frame 24 guide the separated exhaust gas to the separation blade 25, the pre-storage box 21 and the long straight pipe 22 together form an L-shaped channel to ensure that the solid and gas are separated due to inertial impact after contacting the connecting plate 32 and the baffle 33. The solid and gas two-phase flow is actively captured and the fluid kinetic energy at the bend is used to convert it into a constrained flow with clear axial and tangential velocity components. This is used to accurately deliver the exhaust gas in the form of a pre-swirling tight stream to the central area of ​​the funnel-shaped inlet of the separation frame 23 and the climbing frame 24, ensuring that the airflow entering the absorption tower body 1 is stable and reliable. refer to Figure 2 and Figure 7 As shown, the first servo motor 35 then operates, simultaneously driving the active disk 56 to rotate. The active disk 56, through the transmission action of the belt 55, drives the driven disk 54 to rotate synchronously. The driven disk 54 then drives the directional column 51 to rotate along the inside of the long bend 11. When the directional column 51 rotates, it drives the second stirring blade 53 to operate synchronously with the first stirring blade 52, stirring the solid-gas mixture near the junction of the long bend 11 and the waste inlet pipe 31 to prevent waste accumulation in this area. At the same time, the first stirring blade 52 and the second stirring blade 53 rotate at the junction of the long bend 11 and the waste inlet pipe 31, breaking the steady flow layer, particle agglomerates and concentration boundaries formed after the long bend 11 is transported, so that the solid-gas two-phase flow returns to a loose and active preparatory state, making the solid-gas transfer to the connecting disk 32 more stable. The connecting disk 32 can effectively convert more of the gas flow energy into useful work for organizing the swirling flow, rather than being consumed to resist irregular impacts or disturbances, further improving the stability of the absorption tower body 1 in waste treatment. refer to Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, when the exhaust gas comes into contact with the separating blades 25, the second servo motor 47 drives the gear 48 to rotate synchronously inside the connecting ring disk 41 and the stabilizing ring frame 42. Then, the gear 48 meshes with the gear ring 45, driving the receiving ring 43 to rotate synchronously inside the stabilizing ring frame 42 and the connecting ring disk 41. Following this, the rotation of the gear ring 45 drives the centering ring 46 to rotate inside the stabilizing ring frame 42. The end of the centering ring 46 has a floating gap with the output end of the second servo motor 47 to reduce interference with the rotation of the gear 48. As the receiving ring 43 rotates, it drives the separation blade 25 to rotate synchronously. Subsequently, the separation blade 25 drives the support cylinder 27 to rotate synchronously along one end of the climbing frame 24. The structure of the conical spiral guide ring frame 44 performs axial compression and radial diffusion on the incoming flow, while the rotating thread provides the airflow with a basic and adjustable rotational shear force field. Its rotational speed is synchronized with that of the separation blade 25, avoiding abrupt changes and dissipation of solid and gas at the static connection point. This keeps the particulate matter in a controlled state of suspension and diffusion, laying a stable foundation for the rapid mass transfer reaction in the subsequent absorption tower body 1. refer to Figure 1 and Figure 2As shown, the separation frame 23 and the climbing frame 24 forcibly expand the front end of the separation blade 25 into a trumpet-shaped diffusion section, which is beneficial to the uniform distribution of exhaust gas. The rotation of the separation blade 25 causes the advancing exhaust gas to cut and rotate during this process. During the rotation of the separation blade 25, it cuts and guides the advancing solid-gas mixture. Simultaneously, based on the willow-leaf-shaped structure of the separation blade 25, after cutting into the main swirling flow of the exhaust gas, the rotation of the separation blade 25 generates an extremely high local velocity gradient (shear force). This strong shearing action directly acts on the phase interface, effectively stripping away particle clusters encased in the gas or sweeping away fine dust adhering to the surface of larger particles, allowing the solid particles to be fully exposed to the gas phase. Then, with the continuous rotation of the separation blade 25, it continuously acts on any solid-gas boundary layer attempting to re-establish a stable state, preventing its stable development. This causes the particles to continuously experience acceleration, deceleration, and direction change in the alternating flow field, always remaining in a dynamically active state. The solid particles are fully surrounded and wetted by the gas, eliminating localized concentration zones. This allows the particles to collide evenly and fully with the washing droplets or packing surface within the absorption tower body 1. The separation blades 25, by their own power, cut, split, and recombine the incoming swirling flow, disrupting the solid-gas boundary layer and promoting deep solid-gas separation. After passing through the separation blades 25, the solid-gas mixture enters the receiving ring 43 and is further processed by the conical spiral guide ring 44. Its physical morphology undergoes a fundamental change; the solid particles are no longer discrete phases suspended in the gas but form a highly dispersed, mutually penetrating mixture with the gas. This forces the waste gas to pass evenly through the absorption tower body 1. After the treated solid-gas mixture enters the absorption tower body 1, the initial conditions for gas-liquid-solid three-phase contact are greatly optimized. The evenly distributed airflow smoothly fills the entire tower cross-section, significantly reducing mass transfer resistance and greatly improving the efficiency of the core absorption and reaction processes. This enhances the solid waste separation efficiency of the absorption tower body 1, achieving environmental compliance.

[0020] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
