Description

Technical Field

[0001] This application relates to the field of waste gas treatment technology, and in particular to a chemical waste gas treatment device. Background Technology

[0002] Currently, in the production processes of certain chemical industries, organic waste gas, mainly composed of organic components, is emitted. Before being discharged to the outside world, the organic waste gas is usually treated by liquid absorption in order to meet the national standards for waste gas discharge.

[0003] In related technologies, when using the absorption method to treat chemical waste gas, the waste gas is usually introduced into an absorption tower. The absorbent sprayed through nozzles inside the tower comes into countercurrent contact with the waste gas to achieve absorption and purification, ultimately meeting emission standards.

[0004] However, in practice, the flow rate of chemical waste gas fluctuates significantly. When a large amount of waste gas enters the absorption tower in a concentrated manner, its upward velocity increases, resulting in a shorter residence time within the tower. This severely affects the sufficient contact between the waste gas and the absorbent, thereby reducing absorption efficiency. Furthermore, direct discharge of untreated waste gas can easily lead to excessive pollutant levels and cause serious environmental pollution.

[0005] To address the aforementioned problems, a chemical waste gas treatment device is now designed. Summary of the Invention

Through a mechanical structure, the device automatically adjusts the residence time of the waste gas within the tower and the amount of absorbent sprayed based on the waste gas flow rate. It also adjusts the number of nozzles sprayed according to the waste gas flow rate, thereby regulating the amount of absorbent sprayed.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] This application provides a chemical waste gas treatment device that can solve the problem of insufficient waste gas purification when a large amount of waste gas enters the absorption tower at one time in related technologies.

[0036] Please see Figures 1-7 A chemical waste gas treatment device includes: a tower body 1, a baffle 2, elastic elements 3, shielding elements 4, a water supply pipe 5, and a linkage assembly 6. The lower end of the tower body 1 is provided with an air inlet pipe 11, the upper end of the tower body 1 is provided with an exhaust pipe 12, and a drain pipe 13 is provided on one side of the lower end of the tower body 1. The baffle 2 is located inside the tower body 1 and is positioned above the air inlet pipe 11. Several sets of elastic elements 3 are provided, and several sets of elastic elements 3 are provided on the tower body 1 and connected to the baffle 2 to pull the baffle 2 to move closer to the air inlet pipe 11.

[0037] The shielding member 4 is provided in several groups, and the shielding members 4 are staggered and distributed inside the tower body 1. The shielding member 4 includes a fixed plate 41, a sliding plate 42, a pushing component 43, a water supply component 44, and several nozzles 45. The fixed plate 41 is provided inside the tower body 1. The sliding plate 42 is slidably disposed inside the fixed plate 41. The pushing component 43 is provided inside the fixed plate 41 and connected to the sliding plate 42 to drive the sliding plate 42 to move. Several nozzles 45 are provided on the sliding plate 42. The water supply component 44 is provided inside the sliding plate 42 and connected to several nozzles 45, so that when the sliding plate 42 drives the nozzles 45 to move to the outside of the fixed plate 41, the water supply component 44 drives the several nozzles 45 located outside the fixed plate 41 to open and spray.

[0038] The water supply pipe 5 is installed on the tower body 1 and connected to several water supply components 44. The linkage component 6 is installed inside the tower body 1 and connected to the baffle 2 and several pushing components 43. When the baffle 2 moves, the linkage component 6 drives several pushing components 43 to run simultaneously.

[0039] When chemical waste gas needs to be purified, the waste gas can be introduced into the tower body 1 through the inlet pipe 11, and connected to the water supply equipment through the water supply pipe 5, so that the absorbent can be introduced into the water supply pipe 5, and then into the nozzle 45 through the water supply component 44. Finally, the absorbent is sprayed out from the nozzle 45 to contact the waste gas for purification, and the purified waste gas is discharged out through the exhaust pipe 12, and the absorbed absorbent is discharged through the drain pipe 13. In this way, when the waste gas enters the tower body 1, the baffle 2 and multiple sets of elastic elements 3 can block and buffer the waste gas, thereby slowing down the flow rate of the waste gas entering the tower body 1 and dispersing the concentrated waste gas to the surrounding area, thereby reducing the flow rate of the waste gas and increasing the contact area between the waste gas and the absorbent. This makes the waste gas purification more uniform and thorough.

[0040] Meanwhile, as the exhaust gas flows upward, the staggered fixed plates 41 extend the flow path of the exhaust gas, thereby further reducing the flow velocity of the exhaust gas in the tower body 1 and increasing the residence time of the exhaust gas in the tower body 1, thus making the exhaust gas purification more complete. When a large amount of exhaust gas enters the tower body 1 at once, the linkage component 6 can drive several pushing components 43 to operate simultaneously. The pushing components 43 push the slide plate 42 out from the fixed plate 41, which further extends the flow path of the exhaust gas. As the slide plate 42 extends, more of the nozzles 45 on the slide plate 42 are exposed. In cooperation with the water supply component 44, the nozzles 45 extend out of the fixed plate 41 and spray absorbent. As the exhaust gas flow rate increases, the flow path of the exhaust gas is extended and the nozzles 45 spray absorbent, which further increases the contact time between the exhaust gas and the absorbent, thereby enhancing the treatment effect of the exhaust gas.

[0041] Conversely, when the exhaust gas flow rate decreases, the slide plate 42 can retract into the fixed plate 41, and the nozzle 45 extending into the fixed plate 41 can stop spraying. This reduces the movement path of the exhaust gas within the tower body 1 and decreases the amount of absorbent sprayed. As a result, the device can automatically adjust the residence time of the exhaust gas within the tower body 1 and the amount of absorbent sprayed according to the exhaust gas flow rate. This not only avoids insufficient purification of the exhaust gas due to excessive exhaust gas flow but also avoids excessive spraying of absorbent due to insufficient exhaust gas flow, thus preventing waste. The device can adaptively adjust according to the exhaust gas flow rate, achieving uniform and sufficient purification of the exhaust gas while minimizing costs. This reduces production costs and is highly practical.

[0042] Please see Figure 3In this embodiment, the elastic element 3 includes a sleeve 31, a guide rod 32, a limiting block 33, and a spring 34. The sleeve 31 is located at the bottom end of the tower body 1. The guide rod 32 is slidably disposed inside the sleeve 31. The top end of the guide rod 32 is connected to the baffle 2. The limiting block 33 is located at the lower end of the guide rod 32 and is slidably disposed inside the sleeve 31. The spring 34 is sleeved on the guide rod 32 and is located inside the sleeve 31. The spring 34 is located at the upper end of the limiting block 33.

[0043] When the exhaust gas blows the baffle 2, the baffle 2 will pull the limiting block 33 upward through the guide rod 32, thereby squeezing the spring 34. In this way, the spring 34 can buffer the impact of the exhaust gas, so as to ensure the structural strength and operational stability of the device. At the same time, when the exhaust gas flow decreases, the baffle 2 can be reset by the elastic force of the spring 34, which is convenient for use.

[0044] Preferably, the top end of the air inlet pipe 11 extends into the tower body 1, and the upper end of the air inlet pipe 11 is located above the bottom end of the tower body 1.

[0045] This prevents the absorbent dripping from the bottom of the tower 1 from entering the air inlet pipe 11, ensuring the stability of the device.

[0046] The air inlet pipe 11 is located within the projection range of the baffle 2 at the bottom end of the tower body 1;

[0047] In this way, after the absorbent purifies the exhaust gas, the falling absorbent will land on the baffle 2, thus preventing the absorbent from dripping directly into the air inlet pipe 11 and affecting the introduction of exhaust gas, making it more convenient to use.

[0048] Please see Figure 6 The pushing component 43 includes a bidirectional screw 431, two sets of connecting rods 432, two sets of first sliders 433, and two sets of second sliders 434. The bidirectional screw 431 is rotatably disposed within the fixed plate 41. The two sets of first sliders 433 are slidably disposed within the fixed plate 41. The two sets of first sliders 433 are respectively sleeved on both ends of the bidirectional screw 431 and threadedly connected to it. The two sets of second sliders 434 are slidably disposed on the slide plate 42. The two sets of connecting rods 432 are disposed within the fixed plate 41. The two sets of connecting rods 432 are distributed in an "X" shape. The two sets of connecting rods 432 are rotatably connected at the center. The two ends of the two sets of connecting rods 432 are respectively hinged to the first sliders 433 and the second sliders 434.

[0049] When the bidirectional screw 431 rotates, the two sets of first sliders 433 move closer or further apart through their threaded connection with the bidirectional screw 431. Then, the two sets of first sliders 433 drive the two sets of connecting rods 432 to move. This, in turn, pushes the second slider 434 to slide on the slide plate 42 through the rotational connection of the two sets of connecting rods 432. When the two sets of first sliders 433 move closer or further apart, they drive the two sets of connecting rods 432 to extend or retract, thereby moving the slide plate 42. This allows the slide plate 42 to extend and retract within the fixed plate 41. At the same time, the connecting rods 432 of the scissor bar structure can reduce the space occupied by the connecting rods 432 themselves while achieving long-distance movement of the slide plate 42, making the device structure more compact and convenient to use.

[0050] Specifically, in this embodiment, the linkage component 6 includes a gear 61, a rack 62, a transmission belt 63, a rotating shaft 64, a first transmission wheel 65, and a plurality of second transmission wheels 66. The rotating shaft 64 is rotatably disposed inside the tower body 1. The gear 61 and the first transmission wheel 65 are both disposed on the rotating shaft 64. The gear 61 is located inside the tower body 1, and the first transmission wheel 65 is disposed on the outside of the tower body 1. The rack 62 is disposed on the baffle 2 and meshes with the gear 61. The plurality of second transmission wheels 66 are respectively sleeved on a plurality of bidirectional screws 431. The transmission belt 63 is sleeved on the first transmission wheel 65 and the plurality of second transmission wheels 66.

[0051] When the baffle 2 moves up and down with the flow of exhaust gas, it drives the rack 62 to rise and fall. This causes the rack 62 to mesh with the gear 61, which in turn drives the first transmission wheel 65 on the rotating shaft 64 to rotate. The first transmission wheel 65 then drives several second transmission wheels 66 to rotate simultaneously via the transmission belt 63. This causes the second transmission wheels 66 to drive several bidirectional screws 431 to rotate, pushing the slide plate 42 to move. In this way, the movement of the slide plate 42 can be linked to the flow of exhaust gas through the baffle 2. When the exhaust gas flow increases, the slide plate 42 extends out of the fixed plate 41, and conversely, when the exhaust gas flow decreases, the slide plate 42 retracts into the fixed plate 41. This not only allows the device to extend and retract the slide plate 42 according to the amount of exhaust gas, but also eliminates the need for a separate drive source, enhancing the stability of the device's operation, reducing equipment costs, and making it easy to use and highly practical.

[0052] More specifically, the tower body 1 is provided with a plurality of tensioning rollers 67, and the plurality of tensioning rollers 67 are all engaged with the transmission belt 63;

[0053] In this way, the transmission belt 63 can be tightly engaged with the first transmission wheel 65 and the second transmission wheel 66 through several tensioning pulleys 67, thereby achieving stable transmission of the second transmission wheel 66 and facilitating its use.

[0054] Furthermore, in this embodiment, the fixing plate 41 includes a plate body 411 and two sets of slide rails 412, the two sets of slide rails 412 are respectively disposed on both sides of the plate body 411, and the sliding plate 42 includes a connecting plate 421 and two sets of limiting plates 422. The connecting plate 421 is located inside the plate body 411, and the two sets of limiting plates 422 are respectively slidably disposed in the two sets of slide rails 412 and cooperate with them.

[0055] In this way, the movement of the connecting plate 421 can be guided and limited by the sliding connection between the two sets of limiting plates 422 and the two sets of slide rails 412, thereby ensuring the accuracy of the movement of the connecting plate 421 and ensuring the stable operation of the equipment.

[0056] Furthermore, the water supply assembly 44 includes an inlet 441, an inlet channel 442, several water supply channels 443, and several through slots 444. The inlet 441 is located on the side of the slide rail 412 near the connecting plate 421. The inlet channel 442 is located within the slide rail 412, and both ends of the inlet channel 442 are connected to the inlet 441 and the water supply pipe 5, respectively. Several water supply channels 443 are located within the connecting plate 421, and the water supply channels 443 connect to several nozzles. The water supply channel 443 is U-shaped and connected to the water inlet 441. Several channels 444 are opened on the limiting plate 422 near the water inlet 441. The channels 444 are located between two adjacent water supply channels 443 and are connected to the water supply channel 443 and the water inlet 441. The channels 443 and channels 444 are distributed in a serpentine pattern. One-way valves 445 are provided at both ends of the water supply channel 443 and the two sets of one-way valves 445 are arranged in opposite directions.

[0057] When the absorbent enters the water supply pipe 5, it flows into the inlet 441 through the inlet channel 442. When the connecting plate 421 moves within the plate body 411, several through slots 444 on the connecting plate 421 move accordingly. When the through slots 444 move to correspond with the inlet 441, the absorbent in the inlet 441 enters the through slots 444. When the absorbent flows away from the plate body 411, it smoothly passes through multiple one-way valves 445 and enters multiple water supply channels 443, thus allowing the absorbent to be sprayed out through the nozzles 45 on the outside of the plate body 411. Conversely, when the absorbent flows in the opposite direction towards the plate body 411... When the flow is blocked by the one-way valve 445, the flow stops, thus preventing backflow of the absorbent. This allows the connecting plate 421 to move with the change in the flow rate of the waste gas, causing the nozzles 45 that have moved to the outside of the plate body 411 to automatically spray the absorbent, while the nozzles 45 located inside the plate body 411 stop spraying. This automatically adjusts the number of nozzles 45 spraying according to the flow rate of the waste gas, thereby adjusting the amount of absorbent sprayed. In this way, the flow rate of the waste gas, the residence time of the waste gas in the tower body 1, the movement path, and the amount of absorbent sprayed are linked together, enabling the device to achieve adaptive adjustment through mechanical structure. It has wide applicability and strong practicality.

[0058] Preferably, the width of the water inlet 441 is greater than the distance between two adjacent sets of water supply channels 443;

[0059] In this way, when the connecting plate 421 moves within the plate body 411, the inlet 441 can always be connected to any channel 444, thereby ensuring a stable output of the absorbent and preventing the inlet 441 from not being connected to the channel 444 during the movement, which would cause the absorbent to stop flowing. This ensures the stability of the absorbent spray and thus guarantees the purification effect of the exhaust gas.
