Description

Technical Field

[0001] This invention belongs to the field of waste gas treatment technology, specifically relating to an intelligent waste gas treatment device for textile production. Background Technology

[0002] During the production and processing of textiles, such as dyeing, printing, and finishing, a large amount of high-temperature waste gas containing volatile organic compounds (VOCs), formaldehyde, particulate matter, fumes, and odors is generated. If this waste gas is discharged directly without effective treatment, it will not only cause serious air pollution but also endanger the health of operators. Currently, common treatment technologies for textile production waste gas include adsorption methods (such as activated carbon adsorption), spray washing, photocatalytic oxidation, and biodegradation.

[0003] Patent CN120960888B discloses an intelligent waste gas treatment device for textile production, comprising a fixed cylinder, a rotating ring, a mounting plate, and a mounting ring. One end of the rotating ring has an annular groove, which is rotatably connected to the fixed cylinder. The mounting plate is fixedly connected to one end of the inner wall of the rotating ring, and four filter screens are provided on the surface of the mounting plate. The mounting ring is fitted onto one end of the rotating ring. A sealing cover is fixedly connected to the top of the inner wall of the mounting ring, and one end of the sealing cover is connected to a gas guide pipe. A first mounting cover is fixedly connected to the bottom of the inner wall of the mounting ring, and a first motor is fixedly connected to one end of the outer wall of the first mounting cover. The output shaft of the first motor extends into the interior of the first mounting cover and is fixedly connected to a brush plate. A first drain pipe is connected to the bottom end of the first mounting cover. The above application uses a sealing cover in conjunction with a gas guide pipe to transport waste gas, which is then adsorbed and filtered by the filter screens. However, when the air pressure inside the gas guide pipe is low, the filtration effect deteriorates, and when the air pressure is high, the pressure impact range is concentrated, which also affects the filtration effect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an intelligent waste gas treatment device for textile production, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides an intelligent waste gas treatment device for textile production, including a fixed cylinder, an installation plate is installed inside the fixed cylinder, three sets of activated carbon filters are installed inside the installation plate, and air guide pipes are installed inside the fixed cylinder through three brackets. Each air guide pipe is fixed with a sealing cover on the side near the activated carbon filter. Each of the sealing covers is equipped with an adaptive flow guiding assembly, which includes a flow guiding plate and an L-shaped cylindrical bracket fixed to the inner wall of the air guide duct. There are four sets of flow guiding plates, all of which are hinged to the inside of the sealing cover via a pivot. Each pivot is equipped with a torsion spring. A pressure rod is fixed to the inner side of each flow guiding plate, and a metal ball is rotatably connected to the end of each pressure rod. A hollow cone is rotatably connected through the L-shaped cylindrical bracket. Wind turbine blades are fixed in a ring on one side of the hollow cone, and arc-shaped T-shaped rods are slidably connected in a ring on the other side of the hollow cone. A spring is installed between each arc-shaped T-shaped rod and the hollow cone. This application utilizes the combination of a guide plate, torsion spring, pressure rod, metal ball, and hollow cone to cause the wind turbine blades to rotate the hollow cone when the exhaust gas flow or pressure changes. The arc-shaped T-shaped rod pushes the metal ball and pressure rod to automatically adjust the opening and closing angle of the guide plate, achieving dynamic adjustment of the airflow direction. This effectively avoids concentrated airflow impacting a certain area of ​​the activated carbon filter, significantly improving the uniformity and lifespan of the activated carbon filter, and ensuring stable filtration efficiency.

[0006] Preferably, the four metal balls are in contact with the four arc-shaped T-bars respectively. The thickness of the arc-shaped T-bars is one-third of the diameter of the metal balls, and in the initial state, the arc-shaped T-bars are located to the left of the center line of the metal balls.

[0007] Preferably, the part of the hollow cone where the wind turbine blades are installed is located inside the air guide pipe, and the wind turbine blades are in a semi-inclined state, and the length of the wind turbine blades is less than the diameter of the air guide pipe.

[0008] Preferably, the first guide plate is a quarter-circular arc plate, and the first guide plate has a through groove inside.

[0009] Preferably, the sealed cover is internally equipped with a flow-dispersing assembly. This assembly includes two tracks fixed to the inner wall of the sealed cover, a rotating rod penetrating and rotatably connected inside the sealed cover, and a sprocket fixed to the side of the hollow cone. Multiple flow-dispersing plates are slidably connected to the inner wall of the sealed cover via the tracks. Each flow-dispersing plate is connected via a ring rod. The inner wall of the ring rod has friction grooves. A friction wheel is fixed to one side of the rotating rod, and a second sprocket is fixed to the other side. The second sprocket is connected to the first sprocket via a chain. This application utilizes the rotational power of the hollow cone to drive the ring rod to reciprocate via the first sprocket, chain, second sprocket, rotating rod, and friction wheel, driving multiple flow-dispersing plates to slide along the tracks. This creates a dynamic flow field within the sealed cover, effectively disrupting the stratification of exhaust gas velocity, promoting full contact between pollutants and the activated carbon filter, improving the utilization rate of the activated carbon filter, extending the replacement cycle, and reducing operating costs.

[0010] Preferably, the friction wheel and the friction groove opened on the inner wall of the annular rod are in close contact with each other, and each of the spoilers is installed in the same direction.

[0011] Preferably, the top guide plate and the two side guide plates are each equipped with a secondary flow guiding assembly. The secondary flow guiding assembly includes a second guide plate hinged to the inside of the through groove via a second rotating shaft. An arc-shaped rod is fixed to the outer side of the second guide plate, and a spring is fixed between the arc-shaped rod and the outer wall of the first guide plate. This application adds second guide plates to the top and side guide plates. When the first guide plate rotates and unfolds, the arc-shaped rod is squeezed by the inner wall of the sealing cover, and the second guide plate flips outward around the second rotating shaft, guiding the airflow towards the corner area of ​​the activated carbon filter. This solves the problem of low-speed eddies or dead zones at the corners, thereby optimizing the flow field distribution, increasing the adsorption contact time, and is especially suitable for high-concentration VOCs waste gas, improving treatment efficiency.

[0012] Preferably, the arc-shaped rod has the opposite curvature to the second guide plate, and the end of the arc-shaped rod is rotatably connected to a rubber wheel.

[0013] The advantages of this application are: (1) This application uses the combination of a guide plate, a torsion spring, a pressure rod, a metal ball and a hollow cone to make the wind turbine blades rotate when the exhaust gas flow or pressure changes. The arc T-shaped rod pushes the metal ball and the pressure rod to automatically adjust the opening and closing angle of the guide plate, thereby realizing dynamic adjustment of the airflow direction. This can effectively prevent the airflow from concentrating and impacting a certain area of ​​the activated carbon filter, significantly improve the uniformity and lifespan of the activated carbon filter, and ensure stable filtration efficiency.

[0014] (2) This application utilizes the rotational power of the hollow cone barrel, which drives the ring rod to move back and forth via sprocket one, chain, sprocket two, rotating rod and friction wheel, driving multiple baffles to slide along the track, forming a dynamic turbulence field inside the sealed cover. This can effectively break the stratification of exhaust gas velocity, promote full contact between pollutants and activated carbon filter, improve the utilization rate of activated carbon filter, extend the replacement cycle and reduce operating costs.

[0015] (3) In this application, a second guide plate is added to the top and both sides of the guide plate. When the first guide plate is rotated and unfolded, the arc-shaped rod is squeezed by the inner wall of the sealing cover, and the second guide plate flips outward around the second rotating shaft, guiding the airflow to flow towards the corner area of ​​the activated carbon filter, solving the problem of low-speed eddy or dead zone at the corner, thereby optimizing the flow field distribution, increasing the adsorption contact time, and is especially suitable for high-concentration VOCs waste gas, improving the treatment efficiency.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0019] Example 1, as Figures 1-8 As shown, an intelligent waste gas treatment device for textile production includes a fixed cylinder 100, an installation plate 200 is installed inside the fixed cylinder 100, three sets of activated carbon filters 300 are installed inside the installation plate 200, and air guide pipes 500 are installed inside the fixed cylinder 100 via three brackets 400. Each air guide pipe 500 is fixed with a sealing cover 600 on the side near the activated carbon filter 300. Each sealing cover 600 is internally equipped with an adaptive flow guiding assembly 700. The adaptive flow guiding assembly 700 includes a flow guide plate 701 and an L-shaped cylindrical bracket 702 fixed to the inner wall of the air guide duct 500. There are four sets of flow guide plates 701, all of which are hinged to the inside of the sealing cover 600 via a pivot 703. A torsion spring 704 is installed inside each pivot 703. A pressure rod 705 is fixed to the inner side of each flow guide plate 701. A metal ball 706 is rotatably connected to the end of each pressure rod 705. A hollow cone 707 is rotatably connected through the L-shaped cylindrical bracket 702. Wind turbine blades 708 are fixed in a ring-shaped arrangement on one side of the hollow cone 707, and the other side of the hollow cone 707 is... A ring-shaped sliding connection of arc-shaped T-bars 709 is provided. A spring 710 is installed between each arc-shaped T-bar 709 and the hollow cone 707. Four metal balls 706 are in contact with the four arc-shaped T-bars 709 respectively. The thickness of the arc-shaped T-bar 709 is one-third of the diameter of the metal ball 706. In the initial state, the arc-shaped T-bar 709 is located to the left of the center line of the metal ball 706. The part of the hollow cone 707 where the wind turbine blades 708 are installed is located inside the air guide duct 500. The wind turbine blades 708 are in a semi-inclined state. The length of the wind turbine blades 708 is less than the diameter of the air guide duct 500. The first guide plate 701 is a quarter-circular arc plate. A through groove 7011 is opened inside the first guide plate 701. This application utilizes the combination of a guide plate 701, a torsion spring 704, a pressure rod 705, a metal ball 706, and a hollow cone 707. When the exhaust gas flow rate or pressure changes, the fan blades 708 drive the hollow cone 707 to rotate, and the arc-shaped T-rod 709 pushes the metal ball 706 and the pressure rod 705 to automatically adjust the opening and closing angle of the guide plate 701. This achieves dynamic adjustment of the airflow direction, effectively preventing concentrated airflow from impacting a certain area of ​​the activated carbon filter 300, significantly improving the uniformity and lifespan of the activated carbon filter 300, and ensuring stable filtration efficiency.

[0020] In practical use, the exhaust gas enters the sealed cover 600 through the duct 500. When the exhaust gas flow rate or pressure is low, the airflow impact on the wind turbine blades 708 on the hollow cone 707 is small, and the hollow cone 707 does not rotate significantly. The arc-shaped T-bar 709 is in its initial position under the action of the spring 710, with minimal contact with the metal ball 706. The guide plate 701 maintains a small opening and closing angle under the action of the torsion spring 704. The airflow enters the activated carbon filter 300 through the sealed cover 600 in a more concentrated manner. When the exhaust gas flow or pressure increases, the high-speed airflow impacts the wind turbine blades 708. The wind turbine blades 708 drive the hollow cone 707 to rotate around the L-shaped cylindrical support 702. During the rotation of the hollow cone 707, the arc-shaped T-shaped rods 709 distributed in a ring on its outer side rotate accordingly and gradually extend outward under the action of centrifugal force, pushing the metal ball 706 in contact with it. The metal ball 706 transmits the thrust to the guide plate 701 through the pressure rod 705, overcoming the elastic force of the torsion spring 704, so that the guide plate 701 unfolds outward around the rotating shaft 703. Since the four guide plates 701 correspond to the four arc-shaped T-bars 709 respectively, the greater the airflow pressure, the higher the rotation speed of the hollow cone 707, the greater the extension of the arc-shaped T-bars 709, and the greater the opening and closing angle of the guide plates 701, thereby realizing the dynamic adjustment of the airflow direction. This process effectively avoids the airflow from concentrating and impacting a certain local area of ​​the activated carbon filter 300 for a long time, so that the airflow is evenly distributed to the entire surface of the activated carbon filter 300, significantly improving the uniformity of use and life of the activated carbon filter 300, and ensuring the long-term stability of filtration efficiency.

[0021] Example 2, as Figures 7-10As shown, based on Embodiment 1, a turbulence assembly 800 is installed inside the sealing cover 600. The turbulence assembly 800 includes two tracks 801 fixed to the inner wall of the sealing cover 600, a rotating rod 802 that passes through and is rotatably connected inside the sealing cover 600, and a sprocket 805 fixed to the side of the hollow cone 707. Multiple turbulence plates 803 are slidably connected to the inner wall of the sealing cover 600 via the tracks 801. Each turbulence plate 803 is connected via an annular rod 804. The inner wall of the annular rod 804 has a friction groove. A friction wheel 808 is fixed to one side of the rotating rod 802, and a sprocket 806 is fixed to the other side of the rotating rod 802. The sprocket 806 is connected to the sprocket 805 via a chain 807. The friction wheel 808 fits into the friction groove on the inner wall of the annular rod 804. Each turbulence plate 803 is installed in the same direction. This application utilizes the rotational power of the hollow cone 707, which drives the ring rod 804 to reciprocate via sprocket 1 805, chain 807, sprocket 2 806, rotating rod 802, and friction wheel 808. This drives multiple baffles 803 to slide along the track 801, forming a dynamic turbulence field within the sealing cover 600. This effectively breaks down the stratification of exhaust gas velocity, promotes full contact between pollutants and the activated carbon filter 300, improves the utilization rate of the activated carbon filter 300, extends the replacement cycle, and reduces operating costs.

[0022] In practical use, based on Embodiment 1, after the exhaust gas enters the sealing hood 600, the airflow impacts the wind turbine blades 708, causing the hollow cone 707 to rotate. The sprocket 805 on the side of the hollow cone 707 rotates accordingly, transmitting power to the sprocket 806 via the chain 807. The sprocket 806 then drives the coaxial rotating rod 802 to rotate, causing the friction wheel 808 at the end of the rotating rod 802 to rotate as well. The friction wheel 808 is tightly fitted with the friction groove on the inner wall of the ring rod 804. Under the action of friction, the ring rod 804 reciprocates along the direction of the track 801. The ring rod 804 is fixed with multiple baffles 803. The baffles 803 are installed in the same direction. Therefore, the reciprocating motion of the ring rod 804 drives all the baffles 803 to slide synchronously inside the sealing cover 600. The sliding of the baffles 803 breaks the velocity stratification phenomenon of the exhaust gas inside the sealing cover 600, forming a dynamic turbulent field. This allows the pollutants in the exhaust gas to fully contact the surface of the activated carbon filter 300, avoiding airflow "short circuit" or local over-absorption, improving the adsorption utilization rate of the activated carbon filter 300, and extending the replacement cycle of the activated carbon filter 300.

[0023] Example 3, as Figure 4 , Figure 11 and Figure 12As shown, based on Embodiment 1, a secondary flow guiding assembly 900 is installed inside the top guide plate 701 and the two side guide plates 701. The secondary flow guiding assembly 900 includes a guide plate 901 hinged inside the through groove 7011 via a pivot 902. An arc-shaped rod 903 is fixed to the outside of the guide plate 901. A spring piece 905 is fixed between the arc-shaped rod 903 and the outer wall of the guide plate 701. The arc of the arc-shaped rod 903 is opposite to that of the guide plate 901, and a rubber wheel 904 is rotatably connected to the end of the arc-shaped rod 903. This application adds a second guide plate 901 to the top and side guide plates 701. When the first guide plate 701 rotates and unfolds, the arc-shaped rod 903 is squeezed by the inner wall of the sealing cover 600, and the second guide plate 901 flips outward around the second pivot 902, guiding the airflow to flow towards the corner area of ​​the activated carbon filter 300, solving the problem of low-speed eddies or dead zones at the corners, thereby optimizing the flow field distribution, increasing the adsorption contact time, and is especially suitable for high-concentration VOCs waste gas, improving treatment efficiency.

[0024] In specific use, based on Embodiment 1, when the exhaust gas flow rate or pressure is low, the opening angle of the first guide plate 701 is small, the rubber wheel 904 at the end of the arc rod 903 does not contact the inner wall of the sealing cover 600, and the second guide plate 901 remains closed under the action of the spring plate 905. The airflow mainly flows along the main direction of the first guide plate 701. When the exhaust gas flow rate or pressure increases, the first guide plate 701 expands outward under the action of the adaptive flow guiding component 700, and the arc rod 903 moves outward accordingly. The rubber wheel 904 then contacts the inner wall of the sealing cover 600. The inner wall of the cover 600 is contacted and squeezed inward. The arc rod 903 overcomes the elastic force of the spring 905, causing the guide plate 901 to flip outward around the shaft 902 and open. After the guide plate 901 opens, part of the airflow that originally flowed along the direction of the guide plate 701 is guided to the corner area of ​​the activated carbon filter 300, filling the flow gap of the low-speed vortex or dead zone at the corner, increasing the contact time and contact area between the exhaust gas and the activated carbon filter 300, which is especially suitable for the treatment of high-concentration VOCs exhaust gas and effectively improves the filtration efficiency.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
