Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: As Figures 1-7 As shown, the present invention provides a lithium adsorbent product granulation waste gas recovery device, including a frame 1 and a ladder 2 fixedly installed on the outer surface of the frame 1. An inertial dust removal component 3 is fixedly installed on the outer surface of the frame 1. An exhaust pipe 4 is provided on the outer surface of the inertial dust removal component 3. A fan 5 is provided on the outer surface of the frame 1 at the other end of the exhaust pipe 4 away from the inertial dust removal component 3. An exhaust pipe 6 is provided on the outer surface of the fan 5. A dust depth filter component 7 is provided on the outer surface of the frame 1 at the other end of the exhaust pipe 6. An air outlet pipe 8 is provided on the outer surface of the dust depth filter component 7. A volatile organic compound filter component 9 is provided on the outer surface of the frame 1 at the other end of the air outlet pipe 8. An outlet seat 10 is provided on the outer surface of the volatile organic compound filter component 9. A fixing frame 11 is fixedly installed on the outer surface of the frame 1. A slide rail 12 is fixedly installed on the outer surface of the fixing frame 11.

[0032] Specifically, the inertial dust removal component 3 includes a dust collection tank 301. The outer surface of the dust collection tank 301 is provided with a feed inlet 302, a dust outlet 303, and an exhaust pipe 306. The exhaust pipe 306 is connected to the exhaust pipe 4. The advantage is that the waste gas generated during the granulation process enters the dust collection tank 301 through the feed inlet 302. After the waste gas enters, due to the sudden change in the gas flow direction, under the action of inertia, the larger dust particles will collide with the tank wall or other blocking structures, thereby separating from the gas and settling down. This can quickly remove larger dust particles from the waste gas, reduce the load on subsequent processing equipment, avoid large amounts of dust causing blockages and other adverse effects on subsequent finer filtration equipment, and extend the service life of subsequent equipment.

[0033] Specifically, a fixing plate 304 is fixedly installed on the inner surface of the dust collector 301, and a filter groove 305 is opened on the outer surface of the fixing plate 304. There are three identical fixing plates 304, which are evenly distributed. The advantage is that the multiple evenly distributed fixing plates 304 increase the chances of collision and interception of exhaust gas in the dust collector 301, further improving the dust removal effect. It can capture smaller dust particles that cannot be removed by simple inertial impact, and improve the removal capacity of the inertial dust removal component 3 for dust of different particle sizes, making the initial dust removal more thorough. The design of the filter groove 305 provides more attachment and settling positions for dust, which helps to maintain the relative stability of gas flow in the dust collector 301, avoids the dust removal efficiency from being affected by dust drifting randomly, and also facilitates the subsequent cleaning and collection of accumulated dust.

[0034] Specifically, the dust deep filtration assembly 7 includes a removal box 701. A bag filter 702 and an electrostatic precipitator 705 are fixedly installed on the inner surface of the removal box 701. The inner surface of the bag filter 702 is provided with a filter bag body 703 and a mounting frame 704. The advantage is that the exhaust gas after inertial dust removal enters the removal box 701 through an exhaust pipe, etc. The exhaust gas first enters the bag filter 702, passes through the filter bag body 703, and dust particles are intercepted by the filter bag body 703 and adhere to its surface. The gas after filtration continues to flow within the removal box 701. The bag filter 702, utilizing the filtration effect of the filter bag body 703, can efficiently remove smaller dust particles, performing deep filtration on the exhaust gas after inertial dust removal. This greatly reduces the dust content in the exhaust gas, ensuring that subsequent volatile organic compound (VOC) filtration components 9 are not interfered with by dust issues, and improving the overall processing accuracy of the exhaust gas recovery device.

The advantage is that the power supply of the electrostatic precipitator 705 is connected through the connecting end 706, so that the electrostatic field is generated to adsorb dust particles. The purified gas treated by the electrostatic precipitator 705 is discharged from the air outlet groove 707 on the removal box 701 into the volatile organic compound filter assembly 9, which can further improve the dust removal effect.

[0037] Specifically, the volatile organic compound filter assembly 9 includes a filter box 901, the outer surface of the filter box 901 is provided with an air inlet 902, and the inner surface of the filter box 901 is fixedly installed with a filter plate one 903 and a filter plate two 904. The advantage is that the filter plate one 903 and the filter plate two 904 form a multi-stage organic compound filtering structure, which can remove different types and properties of volatile organic compounds, improve the removal efficiency of organic components in complex component waste gas, ensure that the discharged gas meets environmental protection requirements, and reduce pollution to the atmospheric environment.

[0038] Specifically, the sliding rail 12 is slidably connected with the collecting box 13, the inner surface of the collecting box 13 is fixedly installed with the inclined plate 14, the top of the collecting box 13 is classically provided with the top cover 15, the other end of the top cover 15 away from the collecting box 13 is provided with the connecting pipe one 16 and the connecting pipe two 17, the connecting pipe one 16 is matched with the inertia dust removal assembly 3, and the connecting pipe two 17 is matched with the dust deep filtration assembly 7. The advantage is that the sliding connection of the sliding rail 12 and the collecting box 13 facilitates the positioning and movement of the collecting box 13, so that it can be flexibly connected to different dust removal positions, improving the convenience and accuracy of waste collection, reducing the workload of manual carrying and alignment, the design of the inclined plate 14 is conducive to the better accumulation and concentration of waste in the collecting box 13, facilitating subsequent cleaning operation, and the top cover 15 prevents waste from scattering out during the collection process to cause secondary pollution while ensuring normal collection.
