[0002] With the rapid development of the automotive and rubber industries, tire production is increasing every year, and the amount of waste tires generated is also increasing. Waste tires are known as one of the most difficult types of waste to handle because they are difficult to degrade and pollute the environment. The accumulation of large amounts of waste tires not only occupies land but also easily causes fires, resulting in a huge waste of resources. Catalytic cracking is an important means of treating waste tires, which can achieve efficient conversion and resource utilization, while obtaining high-value-added chemical products such as monocyclic aromatic hydrocarbons, low-carbon olefins, and limonene.
[0003] In the prior art, a large amount of flue gas is generated during the catalytic cracking of waste tires. The flue gas contains toxic gases and dust and other impurities, which need to be treated to reduce pollution. Most gas purification equipment uses spraying to purify and clean the flue gas. However, spraying alone cannot fully remove harmful ions from the gas, resulting in poor cleaning effect of the device. Moreover, the purification mechanism is inconvenient to maintain. Therefore, in order to solve the above problems, this utility model proposes a flue gas dust removal device for a waste tire catalytic cracking device. Utility Model Content

[0022] 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.
[0023] Please see Figures 1-6A flue gas dust removal device for a waste tire catalytic cracking unit includes a tank body 1. Fixed rods 2 are fixedly installed in the front and rear sections of the inner cavity of the tank body 1. Four grooves 3 are evenly distributed at the bottom of each fixed rod 2. An anode plate 4 is installed at the bottom of each fixed rod 2. Ribs 5 are fixedly installed on the upper part of the anode plate 4, and the ribs 5 fit into the grooves 3. A cavity 6 is formed on the right side of each groove 3, and a hydraulic rod 7 is fixedly installed in the cavity 6. The telescopic end of the hydraulic rod 7 is movably connected to the groove 3. Two grooves 8 are formed on the right side of each rib 5, symmetrically distributed front and back, and engage with the telescopic end of the hydraulic rod 7. Three fixing frames 9 are fixedly installed between the two fixed rods 2, each located between one of the two anode plates 4. A cathode mesh 10 is fixedly installed inside the cavity of the fixed frame 9. A maintenance plate 11 is fixedly installed at the front of the tank body 1. A valve 12 is fixedly sleeved on the right side of the tank body 1. A water pipe 13 is fixedly installed on the right side of the valve 12. A spray rod 14 is fixedly installed on the left side of the valve 12, inside the cavity of the tank body 1. Six sprayers 15 are evenly fixedly installed at the bottom of the spray rod 14, located above the anode plate 4. A gas collecting chamber 16 is fixedly installed on the upper part of the tank body 1. A hot air blower 17 is fixedly installed on the left side of the gas collecting chamber 16. An exhaust port 18 is opened on the right side of the gas collecting chamber 16. A collection box 19 is fixedly installed at the bottom of the tank body 1. A valve 20 is fixedly sleeved on the right side of the collection box 19. A water pipe 13 is fixedly installed on the right side of the valve 20. With drain pipe 21, hot air blower 17 is turned on to introduce hot air into gas collection chamber 16, accelerating the airflow velocity in the upper part of the inner cavity of tank 1, creating a negative pressure zone in the upper part of the inner cavity of tank 1. This causes the gas at the bottom of the inner cavity of tank 1 to rise and pass through the gap between anode plate 4 and cathode mesh 10. When anode plate 4 and cathode mesh 10 are energized, negative ions in the air move towards anode plate 4, causing residual harmful ions and dust in the gas to adhere to anode plate 4, thoroughly cleaning the smoke and harmful substances in the gas, improving the dust removal and cleaning effect of the device, and preventing pollution of the surrounding environment due to unsatisfactory gas purification. Valve 12 is opened and spray liquid is introduced into spray bar 14 through water pipe 13, and sprayer 15 is started to spray the anode plate. 4. Spraying the surface washes away impurities attached to the anode plate 4. Wastewater falls into the inner cavity of the collection box 19. By opening valve 20, the wastewater is discharged from drain pipe 21. The purified gas enters the inner cavity of the gas collection chamber 16 and is quickly dried by hot air. Finally, it is discharged from the exhaust port 18. When the device is under maintenance, the inspection plate 11 is removed first. The hydraulic rod 7 is activated to disconnect the locking between its extension end and the groove 8. The anode plate 4 is removed from the fixing rod 2 by the engagement between the sliding groove 3 and the rib 5. This makes it easy to replace the anode plate 4, which is beneficial for the maintenance of the device by the staff in the later stage. It improves the maintenance efficiency of the ion adsorption mechanism and avoids the time spent on maintenance affecting the working efficiency of the device.

A gas supply pipe 32 is fixedly installed on the left side of valve 4 31. A valve 33 is fixedly connected to the bottom of tank 31. A drain pipe 34 is fixedly installed on the left side of valve 33. Opening valve 31 allows the flue gas generated by waste tire pyrolysis to enter the inner cavity of tank 25 through gas pipe 32. Then, opening valve 36 and using water pipe 27 allows alkaline spray liquid to enter the spraying device 29 through connecting pipe 28. The spray liquid is fed into the spraying horizontal pipe 292 through spraying ring pipe 291. Opening sprayer 293 allows the spray liquid to spray the flue gas entering the inner cavity of tank 25. The system employs a multi-layer spraying mechanism to ensure thorough contact between the spray liquid and the flue gas, removing dust and sulfides. The sprayed wastewater falls into the bottom of the inner cavity of tank 25. Valve 5 33 is opened to discharge the wastewater through drain pipe 2 34 for recycling, thus improving the environmental efficiency of the device. The gas, after initial purification, enters gas transmission pipe 2 24 and, driven by gas pump 23, enters the bottom of the inner cavity of tank 1 through gas transmission pipe 1 22 for subsequent purification.
[0025] Working principle: Opening valve 4 (31) allows the flue gas generated from waste tire pyrolysis to enter the inner cavity of tank 25 through gas pipe 3 (32). Then, opening valve 3 (26) and using water pipe 2 (27) allows alkaline scrubbing liquid to enter the spraying device 29 through connecting pipe 28. The scrubbing liquid is fed into the horizontal spraying pipe 292 through the spraying ring pipe 291. Opening sprayer 293 allows the scrubbing liquid to spray the flue gas entering the inner cavity of tank 25, removing dust and sulfides from the flue gas. After spraying, the wastewater falls into the bottom of the inner cavity of tank 25. Valve 5 33 is opened, allowing the wastewater to be discharged through drain pipe 2 34. The initially purified gas enters the gas supply pipe 2 24 and, driven by the air pump 23, enters the bottom of the inner cavity of tank 1 through gas supply pipe 1 22. The hot air blower 17 is turned on to introduce hot air into the gas collection chamber 16, accelerating the airflow velocity in the upper part of the inner cavity of tank 1, creating a negative pressure zone in the upper part of the inner cavity of tank 1, thereby reducing the airflow at the bottom of the inner cavity of tank 1. Gas rises through the gap between the anode plate 4 and the cathode mesh 10. Electricity is applied to the anode plate 4 and cathode mesh 10, causing negative ions in the air to move towards the anode plate 4. This causes residual harmful ions and dust in the gas to adhere to the anode plate 4. Valve 12 is opened, and the spray liquid is introduced into the spray rod 14 via the water pipe 13. The sprayer 15 is activated to spray the surface of the anode plate 4, thereby washing away the impurities attached to the anode plate 4. Wastewater falls into the inner cavity of the collection box 19. By opening valve 20, the wastewater is discharged from the drain pipe 21. The purified gas enters the inner cavity of the gas collecting chamber 16, where it is quickly dried using hot airflow, and finally discharged from the exhaust port 18. When the device is under maintenance, the inspection plate 11 is removed first. The hydraulic rod 7 is activated to disconnect the locking between its telescopic end and the groove 8. The engagement between the sliding groove 3 and the rib 5 allows the anode plate 4 to be removed from the fixing rod 2, facilitating the replacement of the anode plate 4.
