Description

Technical Field

[0001] This utility model belongs to the field of waste gas purification technology, specifically relating to a diazotization reaction waste gas treatment device. Background Technology

[0002] Diazotization is widely used in chemical production. Diazotization produces a large amount of waste gas, the main components of which are nitrogen (N2), oxygen (O2), carbon dioxide (CO2), carbon monoxide (CO), nitrogen oxides (NOx), and volatile organic compounds (VOCs). These waste gases have an irritating odor, and some components are toxic, posing a serious threat to the environment and human health.

[0003] Currently, common treatment methods for waste gas generated by diazotization reactions include activated carbon adsorption and purified liquid absorption. Activated carbon adsorption utilizes the porous structure and large specific surface area of ​​activated carbon to remove harmful substances from the waste gas through physical adsorption. Existing activated carbon adsorption devices typically place the activated carbon in the waste gas channel, allowing the waste gas to pass through the activated carbon bed in a unidirectional manner. This method leads to saturation at the front end of the activated carbon bed, while the activated carbon at the back end remains underutilized, resulting in resource waste. Furthermore, the unidirectional passage of waste gas through the activated carbon bed causes excessive adsorption load on the front end, easily leading to blockage, reduced filtration efficiency, and shortened service life. Additionally, replacing activated carbon in existing equipment requires first removing the old activated carbon from the equipment and then refilling it with new activated carbon, a cumbersome, time-consuming, and labor-intensive process that disrupts normal operation. Summary of the Invention

[0004] The purpose of this invention is to provide a diazotization reaction waste gas treatment device to solve the problems mentioned in the background art.

[0005] The purpose of this utility model is achieved as follows: a diazotization reaction waste gas treatment device, comprising an adsorption mechanism and a purification mechanism, wherein an air inlet pipe is provided on the left side of the adsorption mechanism, a movable box is provided inside the adsorption mechanism, a placement frame is provided around the movable box, an adsorption box is provided inside the placement frame, a purification mechanism is provided on the right side of the adsorption mechanism, a connecting pipe is provided between the purification mechanism and the adsorption mechanism, a dispersion plate is provided inside the purification mechanism, the dispersion plate is connected to the connecting pipe, air holes are provided on the surface of the dispersion plate, an exhaust pipe is provided on the right side of the purification mechanism, a liquid inlet is provided above the purification mechanism, and a liquid outlet is provided below the purification mechanism.

[0006] The height of the connecting pipe is higher than the liquid level of the purification liquid inside the purification unit.

A throttle is provided at the upper end of the connecting rod.

[0013] A baffle is provided in the middle of the connecting rod, and a return spring is provided between the baffle and the adsorption mechanism.

[0014] Positioning magnets are provided between the translation frame and the placement frame.

[0015] A directional indicator is provided on the outside of the throttle to indicate the adjustment angle of the throttle.

[0016] To ensure airtightness, sealing gaskets are installed between the movable box and the adsorption mechanism, between the placement frame and the clamping wall, and between the adsorption box and the translation frame.

[0017] The beneficial effects of this invention are as follows: The movable box can be easily pulled out of the adsorption mechanism via a handle, eliminating the need for complex disassembly and reassembly, thus reducing operational difficulty. The adsorption box is movably connected to the placement frame, allowing for complete replacement of the adsorption box and significantly shortening the replacement time of the adsorption material. The translation frame is rotatably connected to the placement frame via a steering shaft, allowing the adsorption box to rotate flexibly with the translation frame. This facilitates adjustment of the adsorption box's orientation, ensuring effective utilization of the adsorption material on both the front and rear sides of the adsorption box, increasing the adsorption material utilization rate and reducing production costs. The directional adjustment device, through the plug and sleeve at the lower end of the connecting rod, combined with the throttle operation, allows for quick positioning and fixing of the translation frame. This device, through its dual purification system of adsorption and purification mechanisms, ensures effective purification of waste gas, improving the purification effect.

[0031] The adsorption box 8 has an opening and closing surface 20 on its side, and the opening and closing surface 20 is connected to the adsorption box 8 by fixing bolts 21.

[0032] In use, the waste gas first enters the adsorption mechanism 1, where some harmful components are adsorbed by the adsorption box 8, reducing the concentration of waste gas, lessening the burden on the subsequent purification mechanism 2, and improving the overall treatment efficiency. After adsorption by the adsorption mechanism 1, the waste gas enters the purification mechanism 2 through the connecting pipe 4, where it is evenly dispersed by the dispersion plate 9 and comes into full contact with the purification liquid, further removing residual harmful substances and ensuring that the emitted gas meets environmental protection standards. Multiple pores 10 are provided on the surface of the dispersion plate 9, allowing the waste gas to be evenly dispersed into the purification liquid, increasing the contact area between the waste gas and the purification liquid, and improving the purification effect. The purification liquid inside the purification mechanism 2 can be replaced through the inlet 12 and outlet 13 to ensure good purification capacity.

[0033] Example 2

[0034] like Figure 1-8 As shown, a diazotization reaction waste gas treatment device includes an adsorption mechanism 1 and a purification mechanism 2. An inlet pipe 3 is located on the left side of the adsorption mechanism 1. A movable box 5 is located inside the adsorption mechanism 1. A placement frame 7 is located around the movable box 2. An adsorption box 8 is located inside the placement frame 7. The purification mechanism 2 is located on the right side of the adsorption mechanism 1. A connecting pipe 4 is provided between the purification mechanism 2 and the adsorption mechanism 1. A dispersion disk 9 is located inside the purification mechanism 2 and is connected to the connecting pipe 4. Air holes 10 are provided on the surface of the dispersion disk 9. An exhaust pipe 11 is located on the right side of the purification mechanism 2. A liquid inlet 12 is located above the purification mechanism 2, and a liquid outlet 13 is located below the purification mechanism 2.

[0035] For better performance, a handle 6 is provided on the front side of the movable box 5. The handle 6 facilitates pushing and pulling the movable box 5.

[0036] For better results, the adsorption box 8 has an opening and closing surface 20 on its side, which is connected to the adsorption box 8 by fixing bolts 21. This facilitates quick opening and replacement of the internal adsorption material, avoiding the cumbersome operation of disassembling the entire adsorption box 8.

[0037] For better results, the adsorption mechanism 1 has an internal clamping wall 14, with a limiting groove 15 on the inner side of the clamping wall 14, and a limiting block 16 on the side of the movable box 5. The clamping wall 14 inside the adsorption mechanism 1, along with the limiting groove 15 cooperating with the limiting block 16 on the side of the movable box 5, ensures that the movable box 5 is stably fixed within the adsorption mechanism 1.

[0038] For better results, a pull strip 17 is provided between the movable box 5 and the adsorption mechanism 1. The pull strip 17 is engaged with the movable box 5 and the adsorption mechanism 1 via a shaft head 18. The pull strip 17 is engaged with the movable box 5 and the adsorption mechanism 1 via the shaft head 18, which facilitates the pull-out operation of the movable box 5.

[0039] For better results, a translation frame 19 is provided inside the placement frame 7. The translation frame 19 is rotatably connected to the placement frame 7 via a steering shaft 22. The adsorption box 8 is placed inside the translation frame 19. An adjuster 23 is provided between the placement frame 7 and the adsorption mechanism 1.

[0040] For better performance, the steering mechanism 23 includes a sleeve 24 and a connecting rod 25. The sleeve 24 is fixed to the top of the steering shaft 22, and the connecting rod 25 is connected to the adsorption mechanism 1 via a bearing. A plug 26 is provided at the lower end of the connecting rod 25, which cooperates with the sleeve 24. A throttle 27 is provided at the upper end of the connecting rod 25. A standing plate is provided above the adsorption mechanism 1 to facilitate control of the throttle 27. Furthermore, to save effort and ensure accuracy, an electric motor or similar device can be used to drive the throttle 27.

[0041] For better results, a baffle 28 is provided in the middle of the connecting rod 25, and a return spring 29 is provided between the baffle 28 and the adsorption mechanism 1. The return spring 29 can keep the plug 26 detached from the sleeve 24 and prevent accidental activation of the handle 27 from causing displacement of the adsorption box 8.

[0042] For better results, positioning magnets 30 are provided between the translation frame 19 and the placement frame 7. Through magnetic attraction, it is ensured that the translation frame 19 can stay stably after being rotated to the appropriate position, avoiding shaking of the translation frame 19 due to external interference.

[0043] In use, the waste gas first enters the adsorption mechanism 1, where some harmful components are adsorbed by the adsorption box 8, reducing the concentration of waste gas, lessening the burden on the subsequent purification mechanism 2, and improving the overall treatment efficiency. After adsorption by the adsorption mechanism 1, the waste gas enters the purification mechanism 2 through the connecting pipe 4, where it is evenly dispersed by the dispersion plate 9 and comes into full contact with the purification liquid, further removing residual harmful substances and ensuring that the emitted gas meets environmental protection standards. Multiple pores 10 are provided on the surface of the dispersion plate 9, allowing the waste gas to be evenly dispersed into the purification liquid, increasing the contact area between the waste gas and the purification liquid, and improving the purification effect. The purification liquid inside the purification mechanism 2 can be replaced through the inlet 12 and outlet 13 to ensure good purification capacity.

[0044] Furthermore, to improve the utilization rate of the adsorption material inside the adsorption box 8 and enhance the filtration effect, the orientation of the translation frame 19 and the adsorption box 8 can be adjusted using the directional adjustment device 23. Press the handle 27 to align the plug 26 at the lower end of the connecting rod 25 with the sleeve 24, ensuring a tight fit between the plug 26 and the sleeve 24. Rotate the handle 27 to rotate the connecting rod 25, which in turn drives the steering shaft 22 to rotate through the cooperation of the plug 26 and the sleeve 24, thus adjusting the angle of the translation frame 19 and the adsorption box 8. The adjustment angle can be viewed through the handle 27, and the relative stability of the translation frame 19 is maintained by the adsorption force of the positioning magnet 30. When the adsorption box 8 needs to be replaced, the movable box 5 can be pulled out of the adsorption mechanism 1. The orientation of the placement frame 7 can be adjusted by 90° using the pull bar 17. The pull bar 17 allows for a smooth pulling action between the movable box 5 and the adsorption mechanism 1, facilitating the removal of the adsorption box 8. Replacing the entire adsorption box 8 can effectively reduce the impact on the normal operation of the equipment. When installing the movable box 5, align the limiting block 16 on the side of the movable box 5 with the limiting groove 15 of the inner clamping wall 14 of the adsorption mechanism 1, and push it in a straight line so that the limiting block 16 is fully embedded in the limiting groove 15 to prevent the movable box 5 from shaking.
