Description

Technical Field

[0001] The present invention relates to the technical field of flue gas purification, and in particular to an environmentally friendly lithium battery flue gas direct combustion purification system. Background Art

[0002] With the increase in the cumulative output of new energy vehicles, the harmless and resource-based treatment of waste lithium batteries has become a key link in the national industrial chain, and optimizing the comprehensive recovery rate of valuable metals has become a top priority. The composition of the waste gas generated by the coarse crushing and roasting of the pretreatment process of valuable metal recovery is relatively complex, including VOCS, fluorides and particulate dust, and is characterized by high concentration and low air volume.

[0003] In the prior art, a Chinese patent with publication number "CN213160003U" discloses a flue gas purification device in a waste lithium battery recycling process. After the flue gas enters the interior of the dust removal box, it is drained through the drainage port on the drainage plate, and the gas is divided into multiple parallel airflows to contact the dust removal net, thereby increasing the contact area with the dust removal net to improve its dust removal efficiency. The flue gas after dust removal reaches the interior of the spray tank through the first connecting pipe, and is evenly distributed at the bottom of the bracket through the first nozzle so that the eluent sprayed therefrom can be in full contact with the gas. When the eluent sprayed by the second nozzle is sprayed onto the diverter plate, since the diverter plate is a disc, the eluent forms a water cloth shape and is in full contact with the gas, so that the gas can be fully in contact with the eluent, thereby achieving the purpose of good purification effect, and solving the problem that the existing flue gas treatment device has a slow processing time, the gas finally discharged is not completely purified, and is prone to secondary pollution.

[0004] If the existing lithium battery flue gas is directly discharged, it will cause air pollution. In order to avoid this phenomenon, a flue gas purification device is usually used to purify the flue gas, in which it is essential to achieve the purification effect by spraying water to contact the flue gas. As described above, a disc-shaped diverter plate is used to form the eluent into a water shape to contact the gas, thereby achieving the purification effect. However, the spray liquid in this method is not easy to achieve a uniform spraying effect, which will cause uneven contact between the spray liquid and the flue gas, thereby affecting the purification effect of the flue gas. Therefore, the present invention proposes a lithium battery flue gas direct combustion environmentally friendly purification system to solve the above-mentioned problems. Summary of the invention

[0035] The spray tank 2 is provided with a swing assembly, the swing assembly is provided with a driving shaft 10, the driving shaft 10 is fixedly connected with a mounting block 11, and the mounting block 11 is provided with a spray assembly.

The output shaft 16 extends to the inside of the U-shaped plate 12 at one end away from the drive motor 15. The rotating disk 17 is located inside the U-shaped plate 12. One end of the drive shaft 10 is rotatably installed inside the U-shaped plate 12. The other end extends to the interior of the spray tank 2 and is rotatably connected to the inner side of the spray tank 2; two positioning blocks 13 are fixedly installed on the drive shaft 10, and the two positioning blocks 13 are symmetrically arranged. A sliding rod 18 is fixedly connected between the two positioning blocks 13, and a sliding block 19 is slidably connected to the sliding rod 18. A positioning column 20 is fixedly installed on the sliding block 19. A through hole 21 is opened on the rotating disk 17, and the top end of the rotating disk 17 passes through the positioning column 20. The positioning column 20 is slidably connected to the through hole 21. When the positioning column 20 rotates, the positioning column 20 rotates with the output shaft 16 as the center.

[0037] The spray assembly includes a diverter pipe 22 and multiple mounting plates 23. The diverter pipe 22 is fixedly installed inside the spray tank 2.

Since the spray pipe 27 in the spray assembly is installed on the mounting block 11, the spray water sprayed by the spray pipe 27 will evenly contact the flue gas, thereby improving the efficiency and effect of the flue gas treatment.

[0039] Embodiment 2:

[0040] See also Figure 1-8 On the basis of the first embodiment, a dispersion component is provided on the driving shaft 10, and the smoke entering the spray tank 2 is dispersed by the dispersion component. The dispersion component includes two rotating plates 29 and two arc-shaped plates 30. The two rotating plates 29 are fixedly mounted on the driving shaft 10. The two rotating plates 29 are symmetrically arranged. Bearings 31 are fixedly mounted on the two rotating plates 29. A rotating rod 32 is fixedly connected inside the bearing 31, and a dispersion plate 33 is fixedly connected to the rotating rod 32. A dispersion hole 34 is opened on the side end surface of the dispersion plate 33. The number of the dispersion holes 34 is multiple and arranged in an array. The multiple dispersion holes 34 facilitate better dispersion of the smoke.

[0041] In this embodiment, when the drive shaft 10 swings, the rotating plate 29 in the dispersion assembly will swing along with the drive shaft 10, and the rotating rod 32 on the rotating plate 29 will drive the dispersion plate 33 to swing. The dispersion holes 34 on the dispersion plate 33 will be used to disperse the flue gas entering the spray tank 2, and the dispersed flue gas will be in better contact with the spray water, thereby further improving the effect of flue gas treatment.

[0042] Embodiment three:

[0043] See also Figure 1-8 On the basis of the first embodiment, two arc plates 30 are fixedly installed on the inner side of the spray tank 2, and the two arc plates 30 are symmetrically arranged. The upper end surface of the arc plate 30 is fixedly connected with a tooth block 35, and a gear 36 is fixedly connected on the rotating rod 32 and on the outer side of the dispersion plate 33. The gear 36 meshes with the tooth block 35. Both ends of the rotating rod 32 are on the outer side of the rotating plate 29, which facilitates the meshing of the gear 36 on the rotating rod 32 with the tooth block 35.

[0044] In this embodiment, when the rotating plate 29 swings following the driving shaft 10, the rotating rod 32 will engage with the tooth block 35 on the arc plate 30 through the gear 36, and the rotating rod 32 will be fixed by the bearing 31 and reciprocate between the two rotating rods 32. When the rotating rod 32 reciprocates, the rotating rod 32 will synchronously drive the dispersion plate 33 to reciprocate. Through the reciprocating rotation of the dispersion plate 33, the smoke entering the spray tank 2 can be dispersed into small air flow groups, so that it can better contact with the spray water, thereby improving the efficiency and effect of smoke treatment.

[0045] Working principle:

[0046] When in use, the smoke is passed into the dust removal box 1 through the air inlet pipe 5, and the dust in the smoke is filtered by the dust removal box 1. The filtered smoke enters the spray tank 2 through the first through pipe 6;

[0047] The rotating disk 17 on the output shaft 16 is driven to rotate by the driving motor 15, and the rotation of the rotating disk 17 is used to drive the positioning column 20 to rotate. When the positioning column 20 rotates with the rotating disk 17, the positioning column 20 moves horizontally on the sliding rod 18 through the sliding block 19. At this time, the positioning column 20 performs a lifting movement on the rotating disk 17, and the driving shaft 10 is in a reciprocating swing state through the positioning block 13 on the sliding rod 18. The mounting block 11 installed on the driving shaft 10 will reciprocate and swing with the driving shaft 10;

[0048] At this time, the spray water entering the diversion pipe 22 through the water inlet pipe 24 will enter the telescopic hose 26 through the water outlet pipe 25, and the spray water in the telescopic hose 26 will be sprayed out through the spray pipe 27. Since the spray pipe 27 will swing back and forth with the mounting block 11, the spray water sprayed by the spray pipe 27 will be in uniform contact with the flue gas, thereby improving the efficiency and effect of flue gas treatment;

[0049] When the driving shaft 10 swings, the rotating plate 29 will swing along with the driving shaft 10, and the rotating rod 32 on the rotating plate 29 will drive the dispersion plate 33 to swing, and the dispersion holes 34 on the dispersion plate 33 will be used to disperse the smoke entering the spray tank 2, so that the dispersed smoke can better contact with the spray water;

[0050] When the rotating plate 29 swings along with the driving shaft 10, the rotating rod 32 will mesh with the tooth block 35 on the arc plate 30 through the gear 36, and the rotating rod 32 will be fixed by the bearing 31 and reciprocate between the two rotating rods 32. When the rotating rod 32 reciprocates, the rotating rod 32 will synchronously drive the dispersion plate 33 to reciprocate. Through the reciprocating rotation of the dispersion plate 33, the smoke entering the spray tank 2 can be dispersed into small airflow groups, so that it can better contact with the spray water, thereby improving the efficiency and effect of smoke treatment;

[0051] After being treated, the flue gas in the spray tank 2 will enter the activated carbon adsorption box 3 through the second through pipe 7, and the odor of water, synthetic dissolved organic matter and micro-pollutants will be effectively removed through the activated carbon adsorption tower. The gas purified by the activated carbon adsorption tower will reach the interior of the reaction tank 4 through the third through pipe 8. The carbon dioxide in the flue gas in the reaction tank 4 will fully react with the alkali solution to generate a saturated crystalline liquid of carbonated alkali metals, thereby reducing the flue gas emission, and the purified flue gas will be discharged through the outlet pipe.

[0052] The control method in this technical solution is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in this field. In addition, this application is mainly used to protect mechanical devices, so this technical solution no longer explains in detail the drive motor control method and circuit connection relationship.
