Description

Technical Field

[0001] This invention belongs to the field of waste gas purification technology, and particularly relates to an integrated device for purifying coal tar waste gas. Background Technology

[0002] Coal tar gas is a typical highly polluting industrial waste gas generated during the production processes of coal chemical, coking, iron and steel smelting, and coal gasification industries. It is complex in composition and highly toxic, characterized by high volatility, poor biodegradability, and easy accumulation in the environment. Direct emission of this type of waste gas not only causes environmental problems such as smog and acid rain, but the polycyclic aromatic hydrocarbons it contains are also highly carcinogenic. When inhaled or absorbed through the skin, they can damage the respiratory and nervous systems. Therefore, developing efficient, stable, and low-cost purification technologies has become a critical issue that urgently needs to be addressed in the field of industrial environmental protection.

[0003] Currently, coal tar exhaust gas purification mainly employs activated carbon adsorption integrated devices. These devices primarily consist of a fixed adsorption bed, an intake and exhaust system, a regeneration heating component, and a control system. The fixed adsorption bed is the core functional area, filled with columnar or granular activated carbon. The intake and exhaust system includes an intake pipe, a porous distribution plate, and an exhaust filter layer, responsible for introducing exhaust gas and exporting purified gas. The regeneration heating component typically uses electric heating or steam heating to generate high-temperature nitrogen or hot air, which is introduced into the adsorption bed to achieve desorption and regeneration of the activated carbon.

[0004] However, existing integrated purification devices still have certain technical defects in practical applications: First, existing devices generally use static porous plates as air inlet guide components, which can only achieve preliminary gas dispersion and cannot adapt to fluctuations in waste gas flow. When waste gas or high-temperature gas enters the adsorption bed, it is easy to form a concentrated columnar flow. Some gas directly short-circuits through the center of the adsorption bed, causing the activated carbon in the central area to be rapidly overloaded and saturated or over-regenerated in a short time, while the activated carbon at the edge and lower layer of the adsorption bed is idle for a long time, reducing the overall purification efficiency and regeneration efficiency of the device. Secondly, in existing devices, activated carbon is generally filled into the adsorption bed in a static manner. This causes the activated carbon in the adsorption bed to accumulate and compact, forming adsorption dead zones. As a result, waste gas or high-temperature gas cannot effectively penetrate the bed. This not only affects the adsorption and regeneration quality of the activated carbon, but also shortens the replacement cycle of the activated carbon, thereby increasing the cost of activated carbon consumables.

[0005] Therefore, in view of the above situation, there is an urgent need to develop an integrated coal tar exhaust gas purification device to overcome the shortcomings in current practical applications. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an integrated coal tar exhaust gas purification device to solve the problems mentioned in the background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solution: An integrated coal tar exhaust gas purification device includes a pretreatment module, a main treatment module, and a post-treatment module. The main treatment module is equipped with an adsorption device, which consists of a purification frame, an air inlet cylinder, an exhaust cylinder, and multiple parallel purification cylinders. The air inlet cylinder and the exhaust cylinder are symmetrically fixed at both ends of the purification frame. Connecting pipes and fixed shafts are installed on both the air inlet cylinder and the exhaust cylinder. Multiple parallel purification cylinders are located between the air inlet cylinder and the exhaust cylinder. Multiple purification cylinders are slidably mounted on the purification frame via a movable frame. A rotating mechanism connected to the outer wall of one purification cylinder is fixed on the movable frame. The purification cylinder has symmetrically arranged adsorption chambers and flow guiding chambers on the inner walls at both ends. The adsorption chambers face the direction of the exhaust pipe, and the flow guiding chambers face the direction of the air inlet pipe. An adsorption mechanism is installed in the adsorption chamber, and a turning mechanism is rotatably installed in the adsorption mechanism. The adsorption mechanism is filled with activated carbon that is in contact with the turning mechanism. A flow guiding mechanism is installed in the flow guiding chamber. A central shaft is provided in the middle of the purification cylinder. The central shaft, purification cylinder, adsorption mechanism, turning mechanism, and flow guiding mechanism are all concentric with the fixed shaft. Connecting mechanisms are installed on the central shafts in multiple purification cylinders and on the fixed shafts in the exhaust pipe and air inlet pipe. A linkage mechanism is installed between the inner side of the adsorption mechanism and the outer side of the central shaft. The linkage mechanism consists of a sun gear, a wheel carrier, an internal gear ring, a gear ring carrier, and a planetary assembly. The sun gear is located on the outer side of the central shaft and is concentric with it. The sun gear is fixed to the inner end face of the adsorption mechanism by the wheel carrier. The internal gear ring is rotatably mounted on the inner end face of the adsorption mechanism. A gear ring carrier is concentrically fixed to one side of the internal gear ring. The gear ring carrier is concentric with and fixedly connected to the central shaft. The planetary assembly is located between the internal gear ring and the sun gear.

The planetary gear at one end of the mounting shaft meshes with the inner side of the internal gear ring, and the planetary gear at the other end of the mounting shaft meshes with the outer side of the sun gear.

The inner end face of the turning cylinder is rotatably connected to the adsorption cylinder and the cylinder cover, respectively, and the inner end face of the turning cylinder is fixedly connected to the planetary ring frame. Inclined comb plates are distributed circumferentially on the outer end face of the turning cylinder. The comb plates are located between the adsorption cylinder and the cylinder cover and are in contact with the activated carbon.

[0011] As a further technical solution of the present invention, the flow guiding mechanism includes a flow guiding cylinder, a spiral flow guiding plate and a flow guiding fixing block. The flow guiding cylinder is fixed in the flow guiding cavity by the flow guiding fixing block, and the spiral flow guiding plate is circumferentially distributed on the inner wall of the flow guiding cylinder at equal intervals.

[0012] As a further technical solution of the present invention, the radial dimension of the end of the spiral guide vane near the air intake is greater than the radial dimension of the end near the exhaust.

[0013] As a further technical solution of the present invention, the rotating mechanism includes a rotating motor, a rotating gear and a rotating gear ring. The rotating motor is fixed on a movable frame, and a rotating gear is fixed on the output end of the rotating motor. The rotating gear meshes with the rotating gear ring, and the rotating gear ring is fixed on the outer wall of the purification cylinder.

[0014] As a further technical solution of the present invention, the connecting mechanism includes a slot assembly and a block assembly.

The block assembly is fixed on the end of the central shaft near the intake pipe and on the fixed shaft inside the intake pipe, respectively. Adjacent slot assemblies and block assemblies cooperate with each other.

[0015] As a further technical solution of the present invention, the card slot assembly includes a card slot connecting cylinder, a card slot slide rod, a card slot spring, a card slot seat, a connecting card slot, and a card slot magnetic attractor. The card slot connecting cylinder is fixed on one end of the central shaft near the exhaust pipe and on a fixed shaft inside the exhaust pipe. The card slot connecting cylinder has card slot slide rods that slide with it in the circumferential direction. A card slot spring connected to one side of the card slot connecting cylinder is installed on the card slot slide rod. A card slot seat that is fixedly connected to the card slot slide rod is provided on the other side of the card slot connecting cylinder. A connecting card slot that cooperates with the adjacent card block assembly is distributed on the card slot seat. A card slot magnetic attractor that magnetically cooperates with the adjacent card block assembly is installed in the connecting card slot.

[0016] As a further technical solution of the present invention, the block assembly includes a block connecting cylinder, a block sliding rod, a block spring, a block seat, a locking block, and a block magnetic attractor. The block connecting cylinder is fixed on one end of the central shaft near the air intake cylinder and on a fixed shaft inside the air intake cylinder. The block connecting cylinder has circumferentially distributed block sliding rods that slide with it. A block spring connected to one side of the block connecting cylinder is installed on the block sliding rod. A block seat is provided on the other side of the block connecting cylinder and is fixedly connected to the block sliding rod. The block seat has locking blocks that cooperate with the connecting slots on the adjacent slot seats. A block magnetic attractor that magnetically cooperates with the adjacent slot magnetic attractor is installed on the surface of the locking block. Both the block magnetic attractor and the slot magnetic attractor are electromagnets, and adjacent block magnetic attractors and slot magnetic attractors attract each other when energized.

[0017] Compared with the prior art, the beneficial effects of the present invention are: The intake and exhaust pipes, connected by a purification frame, restrict the rotation of the fixed shaft, keeping it stationary. The fixed shaft, via a connecting mechanism, can be integrated with the central shafts of multiple purification cylinders, further limiting their rotational movement. The rotating mechanism drives multiple parallel purification cylinders to rotate at high speed between the intake and exhaust pipes. These cylinders synchronize the rotation of the adsorption mechanism, the turning mechanism, and the flow guiding mechanism. The flow guiding mechanism, through high-speed rotation, directs the gas flowing from the intake pipe, transforming it from a concentrated columnar flow to a uniform flow across the entire surface. This allows the waste gas or high-temperature gas entering the adsorption chamber to effectively diffuse throughout the adsorption mechanism, achieving cross-sectional absorption of the adsorption mechanism. The full coverage ensures that the waste gas or high-temperature gas can fully contact the activated carbon at any position within the adsorption mechanism. This not only breaks down the concentration stratification in the waste gas, allowing it to enter the adsorption mechanism in a homogeneous manner, ensuring that each activated carbon particle in the adsorption mechanism can contact the waste gas and avoid local overload of the activated carbon, thus improving the purification efficiency and quality of the purification device, but also evenly distributes the high-temperature gas within the adsorption mechanism, allowing each activated carbon particle to fully and effectively contact the high-temperature gas, avoiding local regeneration of the activated carbon, increasing the desorption rate of residual pollutants in the pores of the activated carbon, thereby improving the regeneration quality and efficiency of the activated carbon, extending the replacement cycle of the activated carbon, and reducing costs while increasing efficiency. The adsorption mechanism drives the sun gear to rotate synchronously via a wheel frame. Since the internal gear ring remains stationary along the central axis, the sun gear, through its rotation and interaction with the internal gear ring, drives the planetary assembly to revolve around it. The planetary assembly rotates in the same direction as the sun gear and the adsorption mechanism, but at a lower speed. The planetary assembly drives a turning mechanism to rotate slowly in the same direction within the adsorption mechanism. This slow, in-direction rotation of the turning mechanism agitates the activated carbon within the adsorption mechanism, causing it to be adsorbed... The continuous tumbling within the mechanism not only reduces the speed difference between the tumbling mechanism and the activated carbon, thus lowering the damage rate of the activated carbon during tumbling and achieving gentle tumbling of the activated carbon, but also extends the replacement cycle of the activated carbon, reduces the cost of activated carbon consumables, and reduces the clogging rate of the adsorption mechanism by broken carbon powder. Furthermore, it allows the activated carbon within the adsorption mechanism to continuously rotate, achieving a more even distribution of the activated carbon adsorption load, enabling it to fully and effectively contact the waste gas or high-temperature gas, improving the adsorption efficiency and regeneration quality of the activated carbon, and ultimately enhancing the purification efficiency and quality of the purification device for the waste gas.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0035] like Figures 1 to 13As shown, an integrated coal tar waste gas purification device provided as an embodiment of the present invention includes a pretreatment module, a main treatment module, and a post-treatment module. The pretreatment module is equipped with a condensation device and a filtration device. The main treatment module is equipped with an adsorption device, a catalytic oxidation device, and a biological treatment device. The post-treatment module is equipped with a desulfurization and denitrification device and a misting device. The adsorption device consists of a purification frame 100, an air inlet 110, an exhaust 120, and multiple parallel purification cylinders 200. 110 and 120 are symmetrically fixed at the beginning and end of the purification rack 100. Both the inlet pipe 110 and the outlet pipe 120 are equipped with connecting pipes 130 and fixed shafts 140. Multiple parallel purification cylinders 200 are located between the inlet pipe 110 and the outlet pipe 120. The fixed shaft 140 is concentric with the purification cylinder 200. Multiple purification cylinders 200 are slidably mounted on the purification rack 100 through a movable frame 210. A rotating mechanism 300 connected to the outer wall of one purification cylinder 200 is fixed on the movable frame 210. The purification cylinder 200 has symmetrically arranged adsorption chambers 220 and flow guiding chambers 230 on its inner walls at both ends. The adsorption chambers 220 face the direction of the exhaust pipe 120, and the flow guiding chambers 230 face the direction of the intake pipe 110. An adsorption mechanism 400 is installed in the adsorption chamber 220, and a turning mechanism 500 is rotatably installed in the adsorption mechanism 400. The adsorption mechanism 400 is filled with activated carbon that is in contact with the turning mechanism 500. A flow guiding mechanism 600 is installed in the flow guiding chamber 230. A central shaft 70 is provided in the middle of the purification cylinder 200. 0. The central shaft 700, purification cylinder 200, adsorption mechanism 400, turning mechanism 500 and flow guiding mechanism 600 are all concentric with the fixed shaft 140. The central shaft 700 in the multiple purification cylinders 200 and the fixed shaft 140 in the exhaust cylinder 120 and the air inlet cylinder 110 are all equipped with connecting mechanisms 900. The connecting mechanisms 900 can not only connect the central shaft 700 in two adjacent purification cylinders 200 into a whole, but also connect the central shaft 700 in the purification cylinder 200 to the fixed shaft 140 in the air inlet cylinder 110 and the exhaust cylinder 120 into a whole, respectively. A linkage mechanism 800 is installed between the inner side of the adsorption mechanism 400 and the outer side of the central shaft 700. The linkage mechanism 800 consists of a sun gear 810, a wheel carrier 820, an internal gear ring 830, a gear ring carrier 840, and a planetary assembly 850. The sun gear 810 is located on the outer side of the central shaft 700 and is concentric with it. The sun gear 810 is fixed to the inner end face of the adsorption mechanism 400 by the wheel carrier 820. The internal gear ring 830 is rotatably mounted on the adsorption mechanism 400 by bearings. On the inner end face of the adsorption mechanism 400, a gear ring frame 840 is concentrically fixed on one side of the internal gear ring 830. The gear ring frame 840 is concentric with and fixedly connected to the central shaft 700. The planetary assembly 850 is located between the internal gear ring 830 and the sun gear 810. One end of the planetary assembly 850 is fixedly connected to the inner end face of the flipping mechanism 500, and the other end of the planetary assembly 850 meshes with the internal gear ring 830 and the sun gear 810 respectively. The connecting pipe 130 can transport exhaust gas or high-temperature gas into the inlet pipe 110. The exhaust pipe 120 can transport the purified exhaust gas into the catalytic oxidation device or transport the regenerated high-temperature gas to the outside through the connecting pipe 130. The inlet pipe 110 and the exhaust pipe 120 can restrict the rotation of the fixed shaft 140 through the purification frame 100, so that it always remains stationary. The fixed shaft 140 can be connected to the central shaft 700 in multiple purification cylinders 200 as a whole through the connecting mechanism 900, and its rotational movement can be restricted. The rotating mechanism 300 can drive multiple parallel purification cylinders 200 to rotate at high speed between the inlet cylinder 110 and the exhaust cylinder 120. The purification cylinders 200 drive the adsorption mechanism 400, the turning mechanism 500, and the flow guiding mechanism 600 to revolve synchronously. The flow guiding mechanism 600, through high-speed rotation, can guide the gas transported in the direction of the inlet cylinder 110, changing the gas from a concentrated columnar flow state to a uniform flow state over the entire area. This allows the waste gas or high-temperature gas entering the adsorption chamber 220 to be effectively diffused at all positions of the adsorption mechanism 400, achieving full coverage of the cross-section of the adsorption mechanism 400 and ensuring that the waste gas or high-temperature gas can interact with the contents of the adsorption mechanism 400. The activated carbon at any position is in full contact, which not only breaks down the concentration stratification in the waste gas, allowing it to enter the adsorption unit 400 in a homogeneous manner, ensuring that every activated carbon particle in the adsorption unit 400 can contact the waste gas, avoiding local overload of the activated carbon, and improving the purification efficiency and quality of the purification device, but also evenly distributes the high-temperature gas into the adsorption unit 400, so that each activated carbon particle can fully and effectively contact the high-temperature gas, avoiding local regeneration of the activated carbon, increasing the desorption rate of residual pollutants in the pores of the activated carbon, thereby improving the regeneration quality and efficiency of the activated carbon, extending the replacement cycle of the activated carbon, and reducing costs and increasing efficiency. The adsorption mechanism 400 drives the sun gear 810 to rotate synchronously via the wheel frame 820. Since the internal gear ring 830 remains stationary along with the central axis 700, the sun gear 810, through rotation and its interaction with the internal gear ring 830, drives the planetary assembly 850 to revolve around it. The rotation direction of the planetary assembly 850 is the same as that of the sun gear 810 and the adsorption mechanism 400, but its rotational speed is lower than that of the adsorption mechanism 400 and the sun gear 810. The planetary assembly 850 drives the flipping mechanism 500 to rotate slowly in the same direction within the adsorption mechanism 400. The flipping mechanism 500, through this slow, same-direction rotation within the adsorption mechanism 400, can... By agitating the activated carbon within the adsorption mechanism 400, it is continuously tumbled within the adsorption mechanism 400. This not only reduces the speed difference between the tumbling mechanism 500 and the activated carbon, lowering the damage rate of the activated carbon during tumbling, but also achieves gentle tumbling of the activated carbon, extending the replacement cycle of the activated carbon, reducing the consumable cost of activated carbon, and reducing the clogging rate of the adsorption mechanism 400 by broken carbon powder, but also allows the activated carbon within the adsorption mechanism 400 to continuously change position, achieving a more even distribution of the activated carbon adsorption load, enabling it to fully and effectively contact the waste gas or high-temperature gas, improving the adsorption efficiency and regeneration quality of the activated carbon, and thus improving the purification efficiency and purification quality of the purification device for waste gas.

[0036] In a preferred embodiment, two adjacent purification cylinders 200 can be connected by flanges and bolts, so that multiple purification cylinders 200 are connected in parallel to form an integral structure, which facilitates the simultaneous driving of the rotating mechanism 300. In addition, the movable frame 210, by sliding on the purification frame 100, allows the staff to move a single purification cylinder 200 to the outside of the air inlet 110 and the exhaust 120, thereby facilitating the staff to replace and repair the activated carbon or aging parts inside the single purification cylinder 200, improving the practicality, convenience and sustainability of the device. The sun gear 810 has a central hole in its middle for the central shaft 700 to pass through, and the inner diameter of the central hole is larger than the outer diameter of the central shaft 700.

[0037] like Figures 3 to 11 As shown, in a preferred embodiment of the present invention, the planetary assembly 850 includes a planetary ring carrier 851, a support 852, a mounting shaft 853, and planetary gears 854. The planetary ring carrier 851 is fixed on the inner end face of the flipping mechanism 500. The support 852 is circumferentially distributed on the planetary ring carrier 851. The mounting shaft 853 is rotatably mounted on the support 852. Planetary gears 854 are fixed at both ends of the mounting shaft 853. The planetary gear 854 located at one end of the mounting shaft 853 meshes with the inner side of the internal gear ring 830, and the planetary gear 854 located at the other end of the mounting shaft 853 meshes with the outer side of the sun gear 810.

[0038] When the sun gear 810 rotates at high speed with the adsorption mechanism 400 and the internal gear ring 830 is stationary with the central axis 700, the sun gear 810 can drive multiple planetary gears 854 to revolve around the internal gear ring 830. The multiple planetary gears 854 can drive the planetary ring carrier 851 to revolve. The rotation direction of the planetary ring carrier 851 is the same as the rotation direction of the sun gear 810, but the rotation speed of the planetary ring carrier 851 is lower than the rotation speed of the sun gear 810. This allows the turning mechanism 500 to rotate at a low speed in the same direction within the adsorption mechanism 400. This allows the turning mechanism 500 to gently move the activated carbon within the adsorption mechanism 400, causing it to continuously change position within the adsorption mechanism 400. This achieves full contact between the activated carbon and the waste gas or high-temperature gas, extends the replacement cycle of the activated carbon, reduces the consumable cost of activated carbon, improves the adsorption efficiency and regeneration quality of the activated carbon, and thus improves the purification efficiency and purification quality of the purification device for waste gas.

[0039] In a preferred embodiment, the planetary ring frame 851 is concentric with the central axis 700.

[0040] like Figures 3 to 11 As shown, in a preferred embodiment of the present invention, the adsorption mechanism 400 includes an adsorption cylinder 410, a cylinder cover 420, and an adsorption fixing block 430. The adsorption cylinder 410 is fixed in the adsorption chamber 220 by the adsorption fixing block 430. The cylinder cover 420 is fixed on one side of the adsorption cylinder 410. Both the adsorption cylinder 410 and the cylinder cover 420 are circumferentially distributed with through holes 440. Activated carbon is filled between the adsorption cylinder 410 and the cylinder cover 420. A flipping mechanism 500 is provided between the adsorption cylinder 410 and the cylinder cover 420. The flipping mechanism 500 is rotatably connected to the adsorption cylinder 410 and the cylinder cover 420 respectively by bearings. The inner end face of the adsorption cylinder 410 is fixedly connected to the wheel frame 820. The inner end face of the cylinder cover 420 is rotatably connected to the internal gear ring 830 by bearings.

[0041] The rotating mechanism 300 drives the adsorption cylinder 410 and the cylinder cover 420 to rotate at high speed through the purification cylinder 200. The adsorption cylinder 410 and the cylinder cover 420 can drive the activated carbon between them to rotate at high speed. At the same time, the adsorption cylinder 410 can drive the sun gear 810 to rotate at high speed through the wheel frame 820. The sun gear 810, through cooperation with the internal gear ring 830, can drive the planetary assembly 850 to rotate at low speed in the same direction. This allows the planetary assembly 850 to drive the flipping mechanism 500 to rotate at low speed in the same direction, thereby completing the gentle agitation of the activated carbon and making it continuously change position within the adsorption mechanism 400. This achieves full contact between the activated carbon and the waste gas or high-temperature gas, extends the replacement cycle of the activated carbon, reduces the consumable cost of activated carbon, and improves the adsorption efficiency and regeneration quality of the activated carbon.

[0042] In a preferred embodiment, both the adsorption cylinder 410 and the cylinder cover 420 have circular holes in their middle portions, and both the adsorption cylinder 410 and the cylinder cover 420 have axially extending cylinders in their middle portions. The axially extending cylinders can be connected to the flipping mechanism 500 via bearings, and can also be connected to the internal gear ring 830 and the wheel frame 820 respectively. There is a certain space between the axially extending cylinders on the adsorption cylinder 410 and the cylinder cover 420, which facilitates the effective connection between the planetary assembly 850 and the flipping mechanism 500.

[0043] like Figures 3 to 11 As shown, in a preferred embodiment of the present invention, the turning mechanism 500 includes a turning cylinder 510 and a comb plate 520. The inner end face of the turning cylinder 510 is rotatably connected to the adsorption cylinder 410 and the cylinder cover 420 respectively through bearings, and the inner end face of the turning cylinder 510 is fixedly connected to the planetary ring frame 851. The outer end face of the turning cylinder 510 is circumferentially distributed with inclined comb plates 520. The comb plates 520 are located between the adsorption cylinder 410 and the cylinder cover 420 and are in contact with the activated carbon.

[0044] When the sun gear 810 rotates at high speed with the tilting cylinder 510 and the internal gear ring 830 is stationary with the central axis 700, the sun gear 810 can drive multiple planet gears 854 to revolve around the internal gear ring 830. The multiple planet gears 854 can drive the planetary ring carrier 851 to revolve, and the planetary ring carrier 851 drives the tilting cylinder 510 and the comb plate 520 to rotate. The rotation direction of the comb plate 520 is the same as the rotation direction of the sun gear 810, but its rotation speed is lower than that of the sun gear 810. By rotating at a low speed in the same direction between the adsorption cylinder 410 and the cylinder cover 420, the comb plate 520 can adsorb the active substances inside the adsorption cylinder 410 and the cylinder cover 420. The activated carbon is agitated, causing it to continuously tumble within the adsorption cylinder 410 and the cylinder cover 420. This not only reduces the speed difference between the agitation mechanism 500 and the activated carbon, lowering the damage rate of the activated carbon during agitation, but also achieves gentle agitation of the activated carbon, extending the replacement cycle of the activated carbon and reducing the cost of activated carbon consumables. At the same time, it reduces the clogging rate of the adsorption mechanism 400 by broken carbon powder, and also allows the activated carbon within the adsorption mechanism 400 to continuously change position, achieving a more even distribution of the activated carbon adsorption load. This allows it to fully and effectively contact the waste gas or high-temperature gas, improving the adsorption efficiency and regeneration quality of the activated carbon, thereby enhancing the purification efficiency and purification quality of the purification device for the waste gas.

[0045] In a preferred embodiment, the gap width on the comb plate 520 can be twice the maximum diameter of the activated carbon. This can prevent the activated carbon from clogging on the comb plate 520 and ensure the efficiency and quality of the comb plate 520 in turning the activated carbon.

[0046] like Figures 3 to 9As shown, in a preferred embodiment of the present invention, the flow guiding mechanism 600 includes a flow guiding cylinder 610, a spiral flow guiding plate 620 and a flow guiding fixing block 630. The flow guiding cylinder 610 is fixed in the flow guiding cavity 230 by the flow guiding fixing block 630, and the spiral flow guiding plate 620 is circumferentially distributed on the inner wall of the flow guiding cylinder 610.

[0047] The radial dimension of the spiral guide vane 620 near the intake cylinder 110 is larger than that near the exhaust cylinder 120. That is, the radial dimension of the spiral guide vane 620 gradually decreases from the intake cylinder 110 to the exhaust cylinder 120. When the airflow enters the spiral guide vane 620, the end with the larger radial dimension can use the rotational force to distribute the centrally concentrated airflow circumferentially, laying the foundation for subsequent uniform diffusion. When the airflow is about to flow out of the spiral guide vane 620, the end with the smaller radial dimension can maintain the spiral guidance of the airflow while leaving sufficient space for the full-area air intake of the adsorption cavity 220, so that the previously circumferentially distributed airflow can cover all areas of the adsorption cavity 220 without obstruction, avoiding excessive contact between the airflow and a single area of ​​the adsorption cavity 220.

[0048] The rotating mechanism 300 can drive the guide cylinder 610 and its internal spiral guide vanes 620 to rotate synchronously through the purification cylinder 200. The spiral guide vanes 620, with different radial dimensions at both ends, can guide the gas transported in the direction of the air inlet cylinder 110 through high-speed rotation, changing the gas from a concentrated columnar flow state to a uniform flow state. This allows the waste gas or high-temperature gas entering the adsorption chamber 220 to be effectively diffused at all positions of the adsorption cylinder 410, achieving full coverage of the cross-section of the adsorption cylinder 410 and ensuring that the waste gas or high-temperature gas can fully contact the activated carbon at any position inside the adsorption cylinder 410. This not only breaks down the concentration stratification in the waste gas, allowing it to enter the adsorption cylinder 410 in a homogeneous manner, ensuring that each activated carbon particle in the adsorption cylinder 410 can contact the waste gas and avoid local overload of the activated carbon, thus improving the purification efficiency and quality of the purification device, but also evenly distributes the high-temperature gas into the adsorption cylinder 410, so that each activated carbon particle can fully and effectively contact the high-temperature gas, avoiding local regeneration of the activated carbon, increasing the desorption rate of residual pollutants in the pores of the activated carbon, thereby improving the regeneration quality and efficiency of the activated carbon, extending the replacement cycle of the activated carbon, and reducing costs and increasing efficiency.

[0049] In a preferred embodiment, both the flow guiding fixing block 630 and the adsorption fixing block 430 are preferably arc-shaped block structures with an L-shaped cross section. Both are fixedly connected to the side wall of the purification cylinder 200 by bolts, and sealing strips are installed at the connection between the two and the purification cylinder 200 to ensure the overall sealing performance of the purification cylinder 200 and prevent leakage of waste gas or high-temperature gas.

[0050] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, the rotating mechanism 300 includes a rotating motor 310, a rotating gear 320, and a rotating gear ring 330. The rotating motor 310 is fixed on a movable frame 210, and the rotating gear 320 is fixed on the output end of the rotating motor 310. The rotating gear 320 meshes with the rotating gear ring 330, and the rotating gear ring 330 is fixed to the outer wall of the purification cylinder 200.

[0051] A rotary motor 310 drives a rotary gear 320 to rotate at high speed. The rotary gear 320 drives multiple parallel and fixedly connected purification cylinders 200 to rotate synchronously at high speed through a rotary gear ring 330. By rotating, the purification cylinders 200 can not only drive the flow guiding mechanism 600 and the adsorption mechanism 400 to rotate, but also cooperate with the central shaft 700 and the fixed shaft 140 to allow the linkage mechanism 800 to drive the turning mechanism 500 to rotate at low speed in the same direction within the adsorption mechanism 400. This allows the flow guiding mechanism 600 to guide the gas, and the turning mechanism 500 to gently turn the activated carbon, improving the adsorption efficiency and regeneration quality of the activated carbon, thereby improving the purification efficiency and purification quality of the purification device for waste gas.

[0052] like Figure 3 , Figure 5 , Figure 12 and Figure 13 As shown, in a preferred embodiment of the present invention, the connecting mechanism 900 includes a slot assembly 910 and a block assembly 920. The slot assembly 910 is fixed on the central shaft 700 at one end near the exhaust pipe 120 and on the fixed shaft 140 inside the exhaust pipe 120, respectively. The block assembly 920 is fixed on the central shaft 700 at one end near the intake pipe 110 and on the fixed shaft 140 inside the intake pipe 110, respectively. Adjacent slot assemblies 910 and block assemblies 920 cooperate with each other.

[0053] The slot assembly 910 includes a slot connecting cylinder 911, a slot slide rod 912, a slot spring 913, a slot seat 914, a connecting slot 915, and a slot magnetic attractor 916. The slot connecting cylinder 911 is fixed on one end of the central shaft 700 near the exhaust pipe 120 and on the fixed shaft 140 inside the exhaust pipe 120. The slot connecting cylinder 911 has slot slide rods 912 circumferentially distributed therewith, and a slot spring 913 connected to one side of the slot connecting cylinder 911 is installed on the slot slide rod 912. The other side of the slot connecting cylinder 911 is provided with a slot seat 914 fixedly connected to the slot slide rod 912. The slot seat 914 has connecting slots 915 that cooperate with adjacent slot block assemblies 920. A slot magnetic attractor 916 that magnetically cooperates with the adjacent slot block assembly 920 is installed in the connecting slot 915.

[0054] The locking block assembly 920 includes a locking block connecting cylinder 921, a locking block slide rod 922, a locking block spring 923, a locking block seat 924, a locking block 925, and a locking block magnetic attractor 926. The locking block connecting cylinder 921 is fixed to one end of the central shaft 700 near the air intake cylinder 110 and to a fixed shaft 140 inside the air intake cylinder 110. The locking block connecting cylinder 921 has circumferentially distributed locking block slide rods 922 that slide with it. A locking block spring 923 connected to one side of the locking block connecting cylinder 921 is installed on the locking block slide rod 922. On the other side of the block connecting cylinder 921, there is a block seat 924 that is fixedly connected to the block slide rod 922. The block seat 924 has a number of engaging blocks 925 that cooperate with the connecting slots 915 on the adjacent slot seats 914. The surface of the engaging blocks 925 is equipped with a block magnetic attractor 926 that magnetically cooperates with the adjacent slot magnetic attractor 916. The block magnetic attractor 926 and the slot magnetic attractor 916 are preferably electromagnets, and adjacent block magnetic attractors 926 and slot magnetic attractors 916 attract each other when energized.

[0055] When multiple purification cylinders 200 are connected in parallel and fixedly as a whole, and two purification cylinders 200 located at the first and last ends are respectively engaged with the exhaust pipe 120 and the intake pipe 110, all the locking block magnetic components 926 or locking slot magnetic components 916 on the central shaft 700 and the fixed shaft 140 are in an energized state. The magnetic attraction between adjacent locking block magnetic components 926 and locking slot magnetic components 916 is greater than the sum of the elastic force of the locking slot spring 913 and the locking block spring 923. The adjacent locking block magnetic components 926 and locking slot magnetic components 916 can drive the locking slot seat 914 and the locking block seat 924 to move closer to each other through mutual attraction, so that the locking block 925 on the locking block seat 924 can engage with the connecting locking slot 915 on the locking slot seat 914, thereby completing the connection of two adjacent central shafts 700. Alternatively, the quick connection between the central shaft 700 and the fixed shaft 140 allows multiple central shafts 700 to remain stationary along with the fixed shaft 140. This facilitates the linkage mechanism 800 to effectively and gently agitate the activated carbon by the agitation mechanism 500, reducing the speed difference between the agitation mechanism 500 and the activated carbon, lowering the damage rate of the activated carbon during agitation, extending the replacement cycle of the activated carbon, reducing the cost of activated carbon consumables, and reducing the clogging rate of the adsorption mechanism 400 by broken carbon powder. It also allows the activated carbon within the adsorption mechanism 400 to continuously reposition itself, achieving a more even distribution of the activated carbon adsorption load, enabling it to fully and effectively contact the waste gas or high-temperature gas, improving the adsorption efficiency and regeneration quality of the activated carbon, and thus improving the purification efficiency and quality of the purification device for the waste gas.

[0056] In a preferred embodiment, the engagement of the connecting slot 915 and the engaging block 925 can restrict the rotational movement of the central shaft 700, preventing it from rotating synchronously with the adsorption mechanism 400, thereby preventing the internal gear ring 830 connected to it from rotating.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
