Description

Technical Field

[0001] This invention relates to the field of flue gas filtration, specifically to a flue gas emission purification device for natural rubber production. Background Technology

[0002] In the production of natural rubber, the cleaned rubber is dried and dehydrated using a hot air furnace. The fuel for the hot air furnace is coal, which produces a large amount of black smoke and dust during combustion, which is harmful to human health and the environment.

[0003] Conventional flue gas purification devices on the market generally suffer from prominent drawbacks such as low energy utilization, poor system coordination, short consumable life, and insufficient operating economy. In terms of energy utilization, most of these devices only use the air pump as a single power source for flue gas traction. The kinetic energy of the flue gas after being pressurized by the air pump is directly wasted. In order to improve the separation efficiency of the downstream dust collector, it is often necessary to add speed-increasing equipment. Furthermore, functions such as spray rotation and waste liquid pumping require separate drive motors or liquid pumps, resulting in the superposition of multiple power systems and increased energy consumption.

[0004] In terms of system coordination and purification effect, traditional devices are in a "dispersed and independent" state in each link: the pretreatment unit does not remove particulate matter thoroughly, and a large number of larger particles directly enter the activated carbon filter layer at the back end, which easily clogs the micropores of activated carbon and causes it to fail quickly. This not only increases costs by frequently replacing consumables, but also affects the purification effect due to unstable adsorption performance; the spray structure is mostly a fixed design, with uneven droplet distribution and a large number of spray dead corners, resulting in insufficient gas-liquid contact, which greatly reduces the cooling and fine particulate matter capture effect, making it difficult to achieve deep purification.

[0005] In the pollutant treatment and resource recovery stages, conventional equipment lacks an efficient closed-loop design: either it is not equipped with a waste liquid pumping system, allowing the concentrated pollutant liquid to accumulate in the packing layer, affecting the purification efficiency and easily causing secondary pollution; or it relies on external pumping equipment to achieve liquid discharge, but does not set up a circulating filtration structure, and the spray liquid is mostly used once, which not only wastes water resources but also increases operating costs. In addition, there is no linkage mechanism between the components of each system, the pretreatment, purification, and recovery stages are not well connected, there are many equipment failure points and maintenance is cumbersome, and the long-term reliability and environmental benefits are difficult to guarantee.

[0006] Therefore, there is a need to provide a flue gas emission purification device for natural rubber production, which aims to solve the above problems. Summary of the Invention

[0007] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a flue gas emission purification device for natural rubber production.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a flue gas emission purification device for natural rubber production, comprising a hot air furnace, a ceramic multi-tube dust collector arranged on the outside of the hot air furnace, a connecting pipe connecting the ceramic multi-tube dust collector and the hot air furnace, an exhaust pipe connected to the top of the ceramic multi-tube dust collector, and an activated carbon filter layer arranged at one end of the exhaust pipe near the ceramic multi-tube dust collector. A Tesla speed-increasing valve is installed at the end of the connecting pipe near the ceramic multi-tube dust collector, and a linkage component is installed on the side of the ceramic multi-tube dust collector away from the hot air furnace. The linkage component includes a flue gas purification tower, which is located on the side of the ceramic multi-tube dust collector away from the hot air furnace. The flue gas purification tower has a positioning tube inside, and a power fan is eccentrically rotatably connected inside the positioning tube. An inclined plate is fixedly connected to the bottom of the power fan. A positioning box is fixedly connected to the inner wall of the flue gas purification tower. A fixing column is fixedly connected to the bottom of the inner cavity of the positioning box. A liquid extraction pipe is connected to the bottom of the positioning box, and an arc-shaped pressing rod is slidably connected to the top of the liquid extraction pipe.

[0009] Preferably, the linkage component further includes a positioning frame, which is fixedly connected to the top of the inner cavity of the flue gas purification tower, and a spray structure is rotatably connected to the bottom of the positioning frame. The bottom of the spray structure is fixedly connected to the top of the power fan.

[0010] Preferably, the linkage component further includes an air pump, which is located on the side of the ceramic multi-tube dust collector away from the hot air furnace. The end of the exhaust pipe away from the ceramic multi-tube dust collector is connected to the exhaust end of the air pump, and the exhaust end of the air pump is connected to an outlet pipe. The end of the outlet pipe away from the air pump is connected to the positioning pipe.

[0011] Preferably, the linkage component further includes a first liquid extraction groove, which is located at the bottom of the arc-shaped pressing rod. A second liquid extraction groove is located at the bottom of the arc-shaped pressing rod, and a second sealing ball is located at the bottom of the second liquid extraction groove. A first sealing ball is located at the top of the liquid extraction tube. The arc-shaped pressing rod is slidably connected to the fixed column and the liquid extraction tube. A return spring is sleeved on the outside of the liquid extraction tube. The top of the return spring is fixedly connected to the arc-shaped pressing rod, and the bottom of the return spring is fixedly connected to the bottom of the inner cavity of the positioning box. The inclined plate is always in contact with the arc-shaped pressing rod.

[0012] Preferably, the linkage component further includes a settling box, which is fixedly connected to the outer wall of the flue gas purification tower, and an L-shaped filter plate is slidably connected inside the settling box.

[0013] Preferably, the flue gas purification tower has a packing layer inside, and the end of the liquid extraction pipe away from the positioning box is located at the bottom of the packing layer inside the flue gas purification tower.

[0014] Preferably, the bottom of the settling box is provided with a drain port, the drain port of the settling box is connected to the interior of the flue gas purification tower, and the packing layer inside the flue gas purification tower is located below the drain port of the settling box.

[0015] Preferably, the top of the arc-shaped pressing rod is provided with a drain pipe, and the first liquid extraction tank, the second liquid extraction tank, and the drain pipe are all connected to each other. The end of the drain pipe away from the second liquid extraction tank is connected to the settling box.

[0016] Preferably, the ceramic multi-tube dust collector consists of guide vanes, a cyclone body, an exhaust inner pipe, and a housing, and the bottom of the ceramic multi-tube dust collector is set as a funnel-shaped unloading area.

[0017] Preferably, the Tesla speed-increasing valve has asymmetrically distributed flow-guiding units inside. When gas enters each flow-guiding unit, it is guided to the main flow channel by the structure, while some fluid enters the branch bypass of the unit. Due to the asymmetrical design of the branch bypass, the fluid in the bypass forms an auxiliary jet during the flow process. This jet has a "boosting" effect on the fluid in the main channel, reducing turbulence interference in the main channel and concentrating the fluid energy more in the axial flow. This integrates the originally dispersed fluid kinetic energy into ordered axial kinetic energy, allowing the gas velocity to increase under the same pressure.

[0018] The present invention provides a flue gas emission purification device for natural rubber production. Compared with the prior art, the advantages of the present invention are: The original system relied on an air pump to generate negative pressure to draw the flue gas. This design utilizes the kinetic energy of the flue gas after it has been pressurized by the air pump, and converts it into a higher-speed, orderly airflow through a Tesla speed-increasing valve structure. This not only improves the centrifugal separation efficiency of the downstream ceramic multi-tube dust collector, but more importantly, it uses this high-speed airflow to drive the rotation of the power fan. The power fan's power drives the rotation of the spray structure and the operation of the liquid extraction pump. Relying on the kinetic energy generated by the air pump, it drives three functions: flue gas flow, spray rotation, and liquid circulation. This achieves cascaded utilization of energy and synergy among system components, thereby improving overall energy efficiency.

[0019] A liquid extraction pump driven by a power fan continuously extracts the concentrated pollutant liquid accumulated at the bottom of the packing layer and delivers it to an L-shaped filter plate that can be easily disassembled and cleaned for filtration. The filtered clear liquid is returned to the system for circulation. At the same time, the rotational motion of the spray structure enhances the uniformity of droplet distribution in the tower, promotes mixing and contact with the flue gas, and plays an auxiliary role in further cooling and particulate matter capture.

[0020] Secondly, the ceramic multi-tube dust collector, as a pre-treatment unit, can remove most of the larger particles in the flue gas, reduce the dust load, and provide protection for the activated carbon filter layer at the back end. It effectively prevents the activated carbon micropores from being quickly blocked and becoming ineffective, extends its service life, and maintains stable adsorption performance. Finally, the flue gas that has been preliminarily purified enters the flue gas purification tower for deep cooling, capture of residual fine particles, and absorption of gaseous pollutants.

[0021] Through mechanical design, the kinetic energy of flue gas is used as the driving force to complete the three tasks of "flue gas purification", "liquid circulation" and "online waste liquid treatment" in a coordinated manner. This forms a highly integrated, energy-self-sufficient, and self-maintaining closed-loop purification system, which is superior to conventional devices on the market in terms of long-term operational reliability, energy efficiency, and environmental benefits.

[0022] Based on the above, write a paragraph outlining the drawbacks of commercially available steel bar tensile testing devices. Attached Figure Description

[0027] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0028] Implementation, for example Figures 1 to 5 As shown, an embodiment of the present invention provides a flue gas purification device for natural rubber production, including a hot air furnace 11, a ceramic multi-tube dust collector 12 disposed on the outside of the hot air furnace 11, a connecting pipe 131 connecting the ceramic multi-tube dust collector 12 and the hot air furnace 11, an exhaust pipe 133 connected to the top of the ceramic multi-tube dust collector 12, and an activated carbon filter layer 134 disposed at one end of the exhaust pipe 133 near the ceramic multi-tube dust collector 12. A Tesla speed-increasing valve 132 is provided at the end of the connecting pipe 131 near the ceramic multi-tube dust collector 12, and a linkage component is provided on the side of the ceramic multi-tube dust collector 12 away from the hot air furnace 11. The linkage component includes a flue gas purification tower 22, which is located on the side of the ceramic multi-tube dust collector 12 away from the hot air furnace 11. The flue gas purification tower 22 is connected to a positioning tube 26, and a power fan 27 is eccentrically rotatably connected inside the positioning tube 26. An inclined plate 28 is fixedly connected to the bottom of the power fan 27. A positioning box 29 is fixedly connected to the inner wall of the flue gas purification tower 22. A fixing column 210 is fixedly connected to the bottom of the inner cavity of the positioning box 29. A liquid extraction pipe 214 is connected to the bottom of the positioning box 29, and an arc-shaped pressing rod 211 is slidably connected to the top of the liquid extraction pipe 214.

[0029] The linkage component also includes a positioning frame 24, which is fixedly connected to the top of the inner cavity of the flue gas purification tower 22.

[0030] The linkage component also includes an air pump 21, which is located on the side of the ceramic multi-tube dust collector 12 away from the hot air furnace 11. The end of the exhaust pipe 133 away from the ceramic multi-tube dust collector 12 is connected to the exhaust end of the air pump 21. The exhaust end of the air pump 21 is connected to the exhaust pipe 23, and the end of the exhaust pipe 23 away from the air pump 21 is connected to the positioning pipe 26. It should be noted that the ceramic multi-tube dust collector 12 consists of guide vanes, a cyclone body, an exhaust inner pipe, and a housing, and the bottom of the ceramic multi-tube dust collector 12 is set as a funnel-shaped unloading area; the Tesla speed-increasing valve 132 has asymmetrical guide units distributed inside. When the gas enters each guide unit, it will be guided to the main flow channel by the structure, while some fluid enters the branch bypass of the unit; due to the asymmetrical design of the branch bypass, the fluid in the bypass will form an auxiliary jet during the flow process. This jet will have a "boosting" effect on the fluid in the main channel, reducing turbulence interference in the main channel, making the fluid energy more concentrated in the axial flow, and integrating the originally dispersed fluid kinetic energy into orderly axial kinetic energy, so that the gas velocity can be increased under the same pressure drive.

[0031] like Figures 6 to 11As shown, the linkage assembly also includes a first liquid extraction groove 212, which is located at the bottom of the arc-shaped pressing rod 211. A second liquid extraction groove 213 is located at the bottom of the arc-shaped pressing rod 211, and a second sealing ball 216 is located at the bottom of the second liquid extraction groove 213. A first sealing ball 215 is located at the top of the liquid extraction pipe 214. The arc-shaped pressing rod 211 is slidably connected to the fixed column 210 and the liquid extraction pipe 214. A return spring 217 is sleeved on the outside of the liquid extraction pipe 214. The top of the return spring 217 is fixedly connected to the arc-shaped pressing rod 211, and the bottom of the return spring 217 is fixedly connected to the bottom of the inner cavity of the positioning box 29. The inclined plate 28 is always in contact with the arc-shaped pressing rod 211. The linkage assembly also includes a settling box 219, which is fixedly connected to the outer wall of the flue gas purification tower 22. An L-shaped filter plate 220 is slidably connected inside the settling box 219.

[0032] It should be noted that: the flue gas purification tower 22 is equipped with a packing layer inside. The end of the liquid extraction pipe 214 away from the positioning box 29 is located at the bottom of the packing layer inside the flue gas purification tower 22. The bottom of the settling box 219 is equipped with a drain port, which is connected to the interior of the flue gas purification tower 22. The packing layer inside the flue gas purification tower 22 is located below the drain port of the settling box 219. The top of the arc-shaped pressing rod 211 is equipped with a drain pipe 218. The first liquid extraction tank 212, the second liquid extraction tank 213, and the drain pipe 218 are all connected. The end of the drain pipe 218 away from the second liquid extraction tank 213 is connected to the settling box 219. The spray structure 25 consists of a rotating main shaft, multiple layers of branch pipes, and atomizing nozzles. The branch pipes are evenly distributed along the main shaft, and the rotational motion achieves no dead angle coverage inside the tower. The nozzle is made of silicon carbide, which is highly wear-resistant and corrosion-resistant, and can be used for long-term flushing of flue gas containing particulate matter. A graphite sealing ring is installed at the connection between the rotating spindle and the positioning frame 24, which serves both sealing and lubrication functions to prevent flue gas leakage and rotation jamming. A graphite bearing is installed in the middle of the main shaft of the power fan 27, and the bearing seat is fixed on the support ring on the inner wall of the positioning tube 26 to provide radial positioning for the rotating parts and reduce operating vibration.

[0033] Based on the above embodiments, the following is the complete working process and working principle of the above embodiments: Working principle: In the rubber production process, it needs to be heated and dried. Currently, hot air furnaces are generally used to dehydrate the rubber. During the drying process, coal combustion produces a large amount of flue gas. When the flue gas is released into the air, it will harm the human body and the environment. When the hot blast stove 11 is started, the staff needs to start the air pump 21 simultaneously. The air pump 21 collects the flue gas generated during coal combustion and then pre-treats the particulate matter in the flue gas through the ceramic multi-tube dust collector 12. When the flue gas inside the hot blast stove 11 enters the ceramic multi-tube dust collector 12 through the connecting pipe 131, the flue gas passes through the inside of the Tesla speed-increasing valve 132. The Tesla speed-increasing valve 132 has asymmetrical flow guiding units distributed inside. When the gas enters each flow guiding unit, it is guided to the main flow channel by the structure. At the same time, some fluid enters the branch bypass of the unit. Due to the asymmetrical design of the branch bypass, the fluid in the bypass will form an auxiliary jet during the flow process. This jet will have a "boosting" effect on the fluid in the main channel, reducing turbulence interference in the main channel, making the fluid energy more concentrated in the axial flow, and integrating the originally dispersed fluid kinetic energy into orderly axial kinetic energy, so that the gas velocity can be increased under the same pressure drive. The flue gas flows into the ceramic multi-tube dust collector 12 at high speed. After entering the ceramic multi-tube dust collector 12, the flue gas flows into the cyclone body of the ceramic multi-tube dust collector 12 under the action of gravity. The flue gas is guided by the guide vanes of the ceramic multi-tube dust collector 12 and rotates at high speed in the cylinder. The rotational inertia generates centrifugal force, which separates the particulate matter in the flue gas at the bottom and falls into the unloading area at the bottom of the ceramic multi-tube dust collector 12. The purified gas rises along the exhaust pipe of the ceramic multi-tube dust collector 12 and is finally extracted through the exhaust pipe 133. The purified gas will pass through the exhaust pipe 133, the activated carbon filter layer 134, and the exhaust pipe 23 and be discharged into the interior of the flue gas purification tower 22. At the same time, the purified gas will be filtered again by the activated carbon filter layer 134. Secondly, the ceramic multi-tube dust collector 12, as a pre-treatment unit, can remove most of the larger particles in the flue gas, reduce the dust load, and provide protection for the activated carbon filter layer 134 at the back end. It effectively prevents the activated carbon micropores from being quickly blocked and becoming ineffective, extends its service life, and maintains stable adsorption performance. Finally, the flue gas that has been preliminarily purified enters the flue gas purification tower 22 for deep cooling, capture of residual fine particles, and absorption of gaseous pollutants.

[0034] When the flue gas is discharged into the flue gas purification tower 22 through the exhaust pipe 23, it will flow at high speed inside the positioning pipe 26 under the action of the air pump 21. This will drive the power fan 27 inside the positioning pipe 26 to rotate. During the rotation of the power fan 27, the spray structure 25 will rotate around the positioning frame 24. This will cause the spray structure 25 to change the flow direction inside the flue gas purification tower 22 while cooling the flue gas. This will cause the fine particles in the flue gas to absorb water and fall under the action of gravity. At the same time, unlike the existing technology, the continuous rotation of the spray structure 25 can enable the rotating spray to actively capture the flue gas without dead angles and achieve comprehensive purification efficiency by strengthening the gas-liquid contact.

[0035] The fine particles in the flue gas absorb water and fall into the packing layer inside the flue gas purification tower 22 under the action of gravity. After being filtered by the packing layer, the pollutant concentrate gathers into liquid at the bottom of the packing layer, and the end of the liquid extraction pipe 214 away from the positioning box 29 is set at the bottom of the packing layer inside the flue gas purification tower 22. Meanwhile, as the power fan 27 rotates, it will drive the inclined plate 28 at the bottom to rotate synchronously. As the inclined plate 28 rotates, it will repeatedly squeeze the arc-shaped pressing rod 211. After being squeezed by the inclined plate 28, the arc-shaped pressing rod 211 will slide downward along the liquid extraction tube 214 and the fixed column 210. At the same time, the arc-shaped pressing rod 211 will compress the return spring 217 at the bottom. When the arc-shaped pressing rod 211 is pressed down by the inclined plate 28, as the inclined plate 28 continues to rotate, the return spring 217 will elastically extend and push the arc-shaped pressing rod 211 to rise along the liquid extraction tube 214 and the fixed column 210, so that the top of the arc-shaped pressing rod 211 is always in contact with the bottom of the inclined plate 28. When the return spring 217 elastically extends and pushes the arc-shaped pressing rod 211 to rise, the second sealing ball 216 is located at the connection between the second liquid extraction tank 213 and the first liquid extraction tank 212, so that the inside of the first liquid extraction tank 212 is temporarily sealed. Then, as the arc-shaped pressing rod 211 rises along the liquid extraction pipe 214 and the fixed column 210, the pressure inside the first liquid extraction tank 212 will pull the first sealing ball 215 to rise, and the concentrated contaminant liquid at the bottom of the packing layer will be drawn into the inside of the first liquid extraction tank 212 through the liquid extraction pipe 214. When the inclined plate 28 reciprocates and presses the arc-shaped pressing rod 211 to descend, the first sealing ball 215 comes into contact with the top of the liquid extraction pipe 214, causing the liquid inside the first liquid extraction tank 212 to flow into the second liquid extraction tank 213. At this time, the liquid flow will drive the second sealing ball 216 to rise inside the second liquid extraction tank 213, causing the liquid inside the second liquid extraction tank 213 to flow along the drain pipe 218 into the settling box 219. Subsequently, the L-shaped filter plate 220 will filter the liquid discharged from the drain pipe 218, and the filtered liquid will fall to the bottom of the settling box 219. Finally, it will be discharged into the flue gas purification tower 22 through the drain port at the bottom of the settling box 219. The packing layer inside the flue gas purification tower 22 is set below the drain port of the settling box 219, so that the filtered liquid re-enters the packing layer, achieving a circulation effect.

[0036] The system itself relies on the air pump 21 to generate negative pressure to draw the flue gas. However, this design utilizes the kinetic energy of the flue gas after it has been pressurized by the air pump 21. Through the Tesla speed-increasing valve 132 structure, it is converted into a higher-speed, orderly airflow. This not only improves the centrifugal separation efficiency of the downstream ceramic multi-tube dust collector 12, but more importantly, it uses this high-speed airflow to drive the rotation of the power fan 27. The power of the power fan 27 drives the rotation of the spray structure 25 and the operation of the liquid extraction pump. Relying on the kinetic energy generated by the air pump 21, it drives three functions: flue gas flow, spray rotation, and liquid circulation. This achieves the cascade utilization of energy and the synergy of system components, thereby improving the overall energy efficiency.

[0037] The liquid extraction pump driven by the power fan 27 continuously extracts the concentrated pollutant liquid accumulated at the bottom of the packing layer and delivers it to the L-shaped filter plate 220, which can be easily disassembled and cleaned, for filtration. The filtered clear liquid is returned to the system for circulation. At the same time, the rotation of the spray structure 25 enhances the uniformity of droplet distribution in the tower and promotes mixing and contact with the flue gas, which plays an auxiliary role in further cooling and particulate matter capture.

[0038] Through mechanical design, the kinetic energy of flue gas is used as the driving force to complete the three tasks of "flue gas purification", "liquid circulation" and "online waste liquid treatment" in a coordinated manner. This forms a highly integrated, energy-self-sufficient, and self-maintaining closed-loop purification system, which is superior to conventional devices on the market in terms of long-term operational reliability, energy efficiency, and environmental benefits.
