Description

Technical Field

[0001] This invention belongs to the field of odor purification and treatment technology, specifically relating to an odor purification and treatment device for circulating waste gas treatment. Background Technology

[0002] In industrial production and municipal wastewater treatment, odor purification is a crucial aspect of environmental governance. Ultraviolet (UV) photocatalysis for odor decomposition is widely used due to its high efficiency and lack of secondary pollution. Existing odor purification devices typically employ a fixed structure with an effective ventilation space (such as a fixed cross-sectional area duct). Waste gas is introduced into the device via a negative pressure fan, and then purified using UV light before being discharged.

[0003] However, in actual operating conditions, the exhaust gas volume often changes due to factors such as production load fluctuations and intermittent process operation. When the volume increases, the effective airflow of a fixed cross-sectional area will lead to an increase in air velocity, shortening the residence time of the exhaust gas in the device. Odor molecules cannot fully react with ultraviolet light, resulting in a significant decrease in purification efficiency. When the volume decreases, the reduced air velocity can easily cause local stagnation of exhaust gas in the airflow, which may not only produce byproducts due to excessive reaction, but also increase the risk of condensation inside the equipment and moisture absorption of materials, while reducing the processing efficiency per unit time. Summary of the Invention

[0004] The purpose of this invention is to provide an odor purification treatment device for circulating waste gas treatment, which can dynamically match the "air volume-cross-sectional area" relationship of the odor purification treatment device to optimize the air velocity inside the odor purification treatment device, so that the air velocity fluctuation inside the effective air duct is small, thereby ensuring the residence time of the waste gas inside the odor purification treatment device and ensuring the odor purification treatment effect of the waste gas.

[0005] The specific technical solution adopted by this invention is as follows: An odor purification device for circulating waste gas treatment includes a rectangular box. An air inlet pipe is fixedly connected to the lower front side of the rectangular box, and an air outlet pipe is fixedly connected to the upper rear side of the rectangular box. A negative pressure fan is fixedly connected to the rear side of the air outlet pipe. The air inlet pipe, the rectangular box, the air outlet pipe, and the negative pressure fan are connected in sequence. Two partition plates are slidably connected inside the rectangular box, forming an effective air duct between the two partition plates. The partition plates can slide left and right inside the rectangular box to adjust the width of the effective air duct. An ultraviolet light source is installed inside the effective air duct.

[0006] Furthermore, a first electric telescopic rod is fixedly connected to both sides of the rectangular box, and the piston rod of the first electric telescopic rod is fixedly connected to the partition plate.

[0007] Furthermore, an air intake baffle is fixedly connected to the lower front side of the baffle plate, and the air intake baffle is slidably connected to the inside of the air intake pipe. An air outlet baffle is fixedly connected to the lower rear side of the baffle plate, and the air outlet baffle is slidably connected to the inside of the air outlet pipe. A bellows plate is fixedly connected between the air intake baffle and the side wall of the air intake pipe.

[0008] Furthermore, the rectangular box is fixedly connected to a plurality of horizontally arranged horizontal plates, which are arranged in order from top to bottom. The plurality of horizontal plates divide the space inside the rectangular box into a plurality of horizontal channels, which are connected in sequence. The partition plate includes multiple side partitions, which are slidably connected to multiple horizontal channels. Adjacent side partitions are connected by a short plate, which is located inside the connection between adjacent horizontal channels. The ultraviolet light source includes multiple ultraviolet lamps fixedly connected inside the horizontal channel. The side of the two side partitions inside the same horizontal channel that is close to each other is the inner side of the side partition. A zigzag adjustable reflector is fixedly connected to the inner side of the side partition. The zigzag adjustable reflector has multiple inclined reflective surfaces.

[0009] Furthermore, the zigzag adjustable reflector includes a connecting plate, which is fixedly connected to the inner side of the side partition. A base plate is fixedly connected to the connecting plate, and a telescopic adjustment mechanism is fixedly connected to the base plate. A first fixed side plate and a second fixed side plate are fixedly connected to both ends of one side of the base plate, respectively. A flexible reflector is fixedly connected to the first fixed side plate. One end of the flexible reflector is connected to the first fixed side plate, and the other end of the flexible reflector is a movable end. The movable end of the flexible reflector bypasses the second fixed side plate and is connected to the telescopic adjustment mechanism. A plurality of intermediate supports located between the first and second fixed side plates are also fixedly connected to one side of the base plate. A traction mechanism adapted to the flexible reflector is fixedly connected to the parts of the base plate located between the first fixed side plate and the intermediate supports, between two adjacent intermediate supports, and between the second fixed side plate and the intermediate supports. This traction mechanism is used to pull the flexible reflector and the traction mechanism to bend towards the side closer to the base plate.

[0010] Furthermore, the traction mechanism includes a telescopic adjustment frame fixedly connected to the base plate, a sliding frame is installed on the telescopic adjustment frame, two third rotating shafts and two fourth rotating shafts are rotatably connected to the sliding frame, and a round rod is rotatably connected between the two third rotating shafts and the two fourth rotating shafts. The flexible reflector passes around the third rotating shaft, the round rod and another third rotating shaft in sequence.

[0011] Furthermore, the telescopic adjustment frame includes a guide frame fixedly connected to the base plate, the sliding frame being slidably connected inside the guide frame, and a magnetic adsorption block being fixedly connected inside the guide frame for magnetic adsorption of the sliding frame.

[0012] Furthermore, the telescopic adjustment mechanism includes a second electric telescopic rod fixedly connected to the base plate, the piston rod of the second electric telescopic rod being fixedly connected to a side strip, and the side strip being fixedly connected to the movable end of the flexible reflector.

[0013] Furthermore, one end of the intermediate support is rotatably connected to a fifth rotating shaft, one end of the second fixed side plate is rotatably connected to a second rotating shaft, and the corner of the bottom plate is rotatably connected to a first rotating shaft.

[0014] The technical effects achieved by this invention are as follows: The present invention discloses an odor purification treatment device for circulating exhaust gas treatment. By sliding the partition plate inside a rectangular box left and right, the distance between the two partition plates is changed, thereby adjusting the width of the effective air duct. This allows the cross-sectional size of the effective air duct inside the rectangular box to be adjusted according to the air volume changes of the negative pressure fan. The dynamic matching of the "air volume-cross-sectional area" relationship optimizes the air velocity inside the effective air duct, resulting in smaller fluctuations in the air velocity inside the effective air duct. This ensures the residence time of the exhaust gas inside the odor purification treatment device and guarantees the odor purification effect of the exhaust gas. Attached Figure Description

[0017] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0018] like Figures 1-10 As shown, an odor purification treatment device for circulating waste gas treatment includes a rectangular box 1. An air inlet pipe 2 is fixedly connected to the lower front side of the rectangular box 1, and an air outlet pipe 3 is fixedly connected to the upper rear side of the rectangular box 1. A negative pressure fan 4 is fixedly connected to the rear side of the air outlet pipe 3. The air inlet pipe 2, the rectangular box 1, the air outlet pipe 3, and the negative pressure fan 4 are connected in sequence. At this time, by starting the negative pressure fan 4, a negative pressure is generated inside the rectangular box 1, which adsorbs the external waste gas into the rectangular box 1. An ultraviolet light source 8 is installed inside the rectangular box 1 to purify the odor of the waste gas entering the rectangular box 1. After the odor purification treatment is completed, the waste gas enters the negative pressure fan 4 through the air outlet pipe 3, and then is discharged and re-enters the outside. This process is repeated to achieve circulating treatment of external waste gas.

[0019] The negative pressure fan 4 can adjust its own blade speed to regulate the air volume. The core of this technical solution lies in the modification of the internal structure of the rectangular box 1 to adapt to the changes in the air volume of the negative pressure fan 4. Specifically, two partition plates are slidably connected inside the rectangular box 1. The two partition plates divide the internal space of the rectangular box 1 into an effective air duct and an unventilated space. The effective air duct is the space between the two partition plates, and the unventilated space is the space between the partition plates and the side wall of the rectangular box 1. The partition plates can slide left and right inside the rectangular box 1 to change the distance between the two partition plates and adjust the width of the effective air duct. This allows the cross-sectional size of the effective air duct inside the rectangular box 1 to be adjusted according to the changes in the air volume of the negative pressure fan 4. The dynamic matching of the "air volume-cross-sectional area" relationship optimizes the air velocity inside the effective air duct, making the air velocity fluctuation inside the effective air duct smaller, thereby ensuring the residence time of the exhaust gas inside the odor purification treatment device and ensuring the odor purification treatment effect of the exhaust gas. The ultraviolet light source 8 is installed inside the effective air duct.

[0020] When the air volume increases, the effective duct cross-sectional size can be increased to reduce the phenomenon of shortened exhaust gas residence time due to increased air velocity, thereby reducing the phenomenon of exhaust gas being discharged before it has fully reacted. When the air volume decreases, the effective duct cross-sectional size can be reduced to reduce "local stagnation" caused by low air velocity (where some exhaust gas remains for a long time, which may lead to excessive reaction and the generation of byproducts), thus maintaining the consistency of the purification effect.

[0021] In some embodiments, the movement of the partition plate is as follows: Figures 1-4 As shown, a first electric telescopic rod 10 is fixedly connected to both sides of the rectangular box 1. The piston rod of the first electric telescopic rod 10 is fixedly connected to the partition plate. By activating the first electric telescopic rod 10, the partition plate can be driven to slide left and right inside the rectangular box 1.

[0022] like Figures 1-4 As shown, in some embodiments, an air inlet baffle 6 is fixedly connected to the lower part of the front side of the baffle plate body, and the air inlet baffle 6 is slidably connected to the inside of the air inlet pipe 2. An air outlet baffle 12 is fixedly connected to the lower part of the rear side of the baffle plate body, and the air outlet baffle 12 is slidably connected to the inside of the air outlet pipe 3. Through the air inlet baffle 6, the baffle plate body and the air outlet baffle 12, a stable air duct can be maintained inside the rectangular box 1. At the same time, a bellows plate 7 is fixedly connected between the air inlet baffle 6 and the side wall of the air inlet pipe 2. The bellows plate 7 can block the space between the air inlet baffle 6 and the side wall of the air inlet pipe 2, so that the air force of the negative pressure fan 4 can be concentrated at the effective air duct.

[0023] like Figures 1-4As shown, multiple horizontally arranged horizontal plates 9 are fixedly connected inside the rectangular box 1. The multiple horizontal plates 9 are arranged in order from top to bottom. The multiple horizontal plates 9 divide the space inside the rectangular box 1 into multiple horizontal channels, and the multiple horizontal channels are connected in sequence. It should be noted that the multiple horizontal channels are arranged in the following order from bottom to top: first channel, second channel, third channel, ..., Nth channel. The front end of the first channel is connected to the intake pipe 2, the rear end of the first channel is connected to the rear end of the second channel, the front end of the second channel is connected to the front end of the third channel, and the remaining channels are connected in the above connection manner. The rear end of the Nth channel is connected to the exhaust pipe 3.

[0024] like Figures 2-3 and Figures 5-6 As shown, the partition plate includes multiple side partitions 5, which are slidably connected inside multiple horizontal channels. Adjacent side partitions 5 are connected by a short plate located inside the connection between adjacent horizontal channels. The front end of the lowermost side partition 5 is fixedly connected to the intake partition 6, and the rear end of the uppermost side partition 5 is fixedly connected to the exhaust partition 12.

[0025] Among them, such as Figures 2-5 As shown, the ultraviolet light source 8 includes multiple ultraviolet lamps fixedly connected inside the horizontal channel. The side of the two side partitions 5 inside the same horizontal channel that are close to each other is the inner side of the side partition 5. A zigzag adjustable reflector 11 is fixedly connected to the inner side of the side partition 5. The zigzag adjustable reflector 11 has multiple inclined reflective surfaces. By setting the reflective surfaces of the zigzag adjustable reflector 11, the ultraviolet rays irradiated by the ultraviolet light source 8 inside the horizontal channel can be refracted more evenly inside the horizontal channel.

[0026] The slope of the reflective surface is adjustable. When the side partition 5 moves, the width of the horizontal channel changes. At this time, the angle of ultraviolet refraction of the reflective surface can be changed by adjusting the slope of the reflective surface. This allows the ultraviolet light source 8 to still be refracted relatively evenly inside the horizontal channel after the width of the horizontal channel changes.

[0027] Among them, such as Figure 4 and Figures 6-8As shown, the zigzag-shaped adjustable reflector 11 includes a connecting plate 20, which is fixedly connected to the inner side of the side partition 5. A base plate 13 is fixedly connected to the connecting plate 20, and a telescopic adjustment mechanism is fixedly connected to the base plate 13. A first fixed side plate 14 and a second fixed side plate 17 are fixedly connected to both ends of one side of the base plate 13, respectively. A flexible reflector 15 is fixedly connected to the first fixed side plate 14. One end of the flexible reflector 15 is connected to the first fixed side plate 14, and the other end of the flexible reflector 15 is a movable end. The movable end of the flexible reflector 15 bypasses the second fixed side plate 17 and the telescopic adjustment mechanism. The adjustment mechanism is connected, and a number of intermediate supports 28 located between the first fixed side plate 14 and the second fixed side plate 17 are fixedly connected to one side of the base plate 13. A traction mechanism adapted to the flexible reflector 15 is fixedly connected to the part of the base plate 13 between the first fixed side plate 14 and the intermediate supports 28, between two adjacent intermediate supports 28, and between the second fixed side plate 17 and the intermediate supports 28. The traction mechanism is used to traction the flexible reflector 15 and the position of the traction mechanism relative to each other to bend towards the side closer to the base plate 13, so that the reflective surface formed on the flexible reflector 15 is set at an angle.

[0028] Among them, such as Figures 7-10 As shown, the traction mechanism includes a telescopic adjustment frame fixedly connected to the base plate 13. A sliding frame 22 is installed on the telescopic adjustment frame. Two third rotating shafts 23 and two fourth rotating shafts 25 are rotatably connected to the sliding frame 22. A round rod 24 is rotatably connected between the two third rotating shafts 23 and the two fourth rotating shafts 25. The flexible reflector 15 passes through the third rotating shaft 23, the round rod 24 and the other third rotating shaft 23 in sequence. At this time, the round rod 24 is horizontally limited by the third rotating shaft 23 and the fourth rotating shaft 25, and the flexible reflector 15 is limited by the round rod 24, so that the flexible reflector 15 forms a zigzag shape. At this time, the tilt angle of the flexible reflector 15 can be adjusted by adjusting the position of the round rod 24.

[0029] Meanwhile, the telescopic adjustment bracket can be a motor-driven telescopic bracket or an elastic tension-type telescopic bracket. The motor-driven telescopic bracket is a bracket structure that can actively control the telescopic movement, while the elastic tension-type telescopic bracket is a bracket structure that passively expands and contracts under force.

[0030] The elastic tension telescopic bracket includes a guide frame 21 fixedly connected to the base plate 13, and a sliding frame 22 slidably connected inside the guide frame 21. A magnetic adsorption block 26 is fixedly connected inside the guide frame 21. The magnetic adsorption block 26 can be an electromagnet or a magnet, used to magnetically adsorb the sliding frame 22 which has a magnetic material. The flexible reflector 15 and the traction mechanism are pulled to bend towards the side closer to the base plate 13. When the flexible reflector 15 is pulled by the telescopic adjustment mechanism, the elastic tension telescopic bracket can automatically extend outward under force.

[0031] Meanwhile, the magnetic adsorption block 26 can also be replaced by a tension spring, with one end of the tension spring fixedly connected to the inner wall of the guide frame 21 and the other end of the tension spring fixedly connected to the sliding frame 22.

[0032] The difference between the motor telescopic bracket and the elastic tension telescopic bracket is that the magnetic adsorption block 26 is replaced by a motor fixedly connected to the guide frame 21. The output end of the motor is fixedly connected to a threaded rod that is threadedly connected to the sliding frame 22. By starting the motor, the threaded rod can be driven to move automatically, thereby driving the sliding frame 22 to telescopically move.

[0033] The telescopic adjustment mechanism includes a second electric telescopic rod 27 fixedly connected to the base plate 13. The piston rod of the second electric telescopic rod 27 is fixedly connected to the side strip 16. The side strip 16 is fixedly connected to the movable end of the flexible reflector 15. When the second electric telescopic rod 27 is activated, the side strip 16 is moved, thereby adjusting the tension applied to the flexible reflector 15.

[0034] like Figures 7-10 As shown, one end of the intermediate support 28 is rotatably connected to the fifth rotating shaft 29, one end of the second fixed side plate 17 is rotatably connected to the second rotating shaft 19, and the corner of the bottom plate 13 is rotatably connected to the first rotating shaft 18. The flexible reflector 15 passes around the fifth rotating shaft 29, the second rotating shaft 19 and the first rotating shaft 18 in sequence. By setting the fifth rotating shaft 29, the second rotating shaft 19 and the first rotating shaft 18, the wear and tear on the flexible reflector 15 during movement can be reduced.

[0035] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
