[0002] Lithium ore roasting is an important step in the lithium ore processing process. This process is mainly used to process insoluble lithium ores, such as spodumene, lithium mica, etc., to improve the extractability of lithium. In the process of adding lithium ore to the roasting furnace for roasting, a large amount of high-temperature flue gas will be generated, which needs to be treated with a high-temperature flue gas dust removal device before being discharged into the atmosphere.

[0003] When the existing flue gas dust removal device treats the high-temperature flue gas generated by the roasting of lithium ore, it lacks an effective device for recovering and utilizing the heat in the high-temperature flue gas, resulting in energy waste. In addition, the long-term impact of the high-temperature flue gas on the dust removal structure will reduce its service life.

[0013] Furthermore, a dispersion component is provided in the middle of the dust removal box, and the dispersion component includes an air outlet hood and a fan wheel. An air outlet hood is provided in the middle of the dust removal box, and a fan wheel is rotatably connected inside the air outlet hood, and the air outlet hood is connected to the connecting pipe.

[0014] Furthermore, the dispersion component also includes a limit plate, a scraper ring and a reset spring.

[0015] Furthermore, the other end of the return spring is connected to the shaft rod of the fan wheel, and the scraper ring is elastically connected to the fan wheel through the return spring, and the scraper ring is slidably connected to the fan blades of the fan wheel.

[0016] The present invention provides a high-temperature flue gas dust removal device for lithium ore roasting, which has the following beneficial effects: when in use, the high-temperature flue gas can be cooled first and then dusted, and its heat can be recovered and utilized, and it is also convenient to clean the inside to avoid dust adhesion and accumulation in the device to cause blockage, and the filter element can be replaced in time to ensure the purification effect.

[0017] 1. When the present invention is in use, the flue gas can enter the coil from the three-way valve through an air inlet pipe, and the circulating water in the cooling box can absorb the heat of the flue gas through the coil to cool it down, thereby preventing the high-temperature flue gas from directly contacting the dust removal structure and reducing its service life. After absorbing the heat, the circulating water forms steam and evaporates. After contacting the lower surface of the guide plate, it releases heat and condenses on the lower surface of the guide plate, thereby preheating the material to be processed through the guide plate, recovering the heat of the high-temperature flue gas for easy processing, and the condensed droplets can be on the guide plate. The smoke is restricted from sliding along the inclined surface of the guide plate, entering the temporary storage box, and flowing back to the water tank through the pipe. When the device needs to be cleaned, the passage can be changed through the three-way valve to allow the smoke to enter another air inlet pipe, and then the hot water in the cooling box is pumped out through the flushing pump and sent into the air inlet pipe, so as to flush the air inlet pipe and the coil, and remove the dust adhering to the inner wall of the pipe to avoid dust accumulation and blockage of the pipe. In summary, when in use, the smoke can be cooled, and the heat of the smoke can be recovered and utilized, which is also convenient for cleaning the device.

[0018] 2. After the flue gas is cooled, it enters the air outlet hood from the coil through the connecting pipe. The fan wheel rotates in the air outlet hood under the blowing of the flue gas, thereby breaking up the flue gas and reducing its speed, so that it is evenly dispersed from the air outlet hood to the dust removal box, thereby enhancing the dust removal effect on the flue gas. When the flue gas drives the fan wheel to rotate, the scraper ring slides on the surface of the fan blade under the action of centrifugal force and stretches the reset spring. Different flue gas flow rates will generate different centrifugal forces, and the moving distance of the scraper ring will be different, so that the scraper ring moves back and forth on the fan blade under the action of the reset spring, The surface of the blades is cleaned so that dust with low adhesion leaves the exhaust hood along with the flue gas, and the limit plate prevents the scraper ring from falling off the blade when the centrifugal force is too strong. When the device is cleaned, hot water enters the exhaust hood from the coil through the connecting pipe, which can also flush the fan wheel and drive the fan wheel to rotate. The power of the flushing pump can be adjusted to control the hot water flow rate, so that the scraper ring can comprehensively clean the fan blades to avoid dust adhesion and accumulation. In summary, when in use, the flue gas can be broken up and slowed down to enhance the dust removal effect on the flue gas and clean the fan blades.

[0019] 3. In the present invention, after the flue gas enters the dust removal box, the water outlet pump draws the circulating water in the water tank into the annular pipe and sprays it into the dust removal box to settle the dust in the flue gas and neutralize the flue gas. After the dust falls, it is intercepted by the sieve plate. At the same time, the sieve plate exerts force on the vibration spring under the impact of water and dust, so that the vibration spring drives the sieve plate to vibrate repeatedly in the vibration chamber, so that the trapped dust slides along the inclined surface of the sieve plate and leaves the dust removal box from the dust removal port. The water can pass through the sieve plate to reach the lower part of the dust removal box and be drawn into the cooling box by the return water pump to supplement the circulating water in the cooling box. The flue gas with dust removed continues to rise, and the activated carbon plate can The residual dust and odor in the dust removal box are absorbed, and the purified flue gas leaves the dust removal box and is discharged into the outside. As the amount of material absorbed by the activated carbon board increases, its weight also increases, and the supporting spring can be compressed through the bottom plate. The pressure sensor monitors the force of the supporting spring. When the force of the supporting spring reaches a predetermined value, the adsorption amount of the activated carbon board reaches the limit. At this time, the bottom frame can be pulled out of the installation slot and the activated carbon board can be replaced to ensure the purification effect. In summary, during use, the dust can be automatically discharged and the adsorption state of the activated carbon board can be monitored to facilitate its replacement.

[0030] The specific operation is as follows. When in use, the flue gas can enter the coil 202 from the three-way valve 210 through an air inlet pipe 203. The circulating water in the cooling box 201 can absorb the heat of the flue gas through the coil 202 to cool it down, so as to avoid the high-temperature flue gas from directly contacting the dust removal structure and reducing its service life. After absorbing the heat, the circulating water forms steam and evaporates.

In summary, when in use, the smoke can be cooled, and the heat of the smoke can be recovered and utilized, which is also convenient for cleaning the device.

The air outlet cover 1701 is arranged in the middle of the dust removal box 6, and the fan wheel 1702 is rotatably connected in the air outlet cover 1701. The air outlet cover 1701 is connected to the connecting pipe 204, and the dispersion component 17 also includes a limit plate 1703, a scraper ring 1704 and a reset plate 1704. Spring 1705, one end of the fan blade of the fan wheel 1702 is connected to the limit plate 1703, and a scraper ring 1704 is arranged on the outer side of the fan blade of the fan wheel 1702, and the two sides of the scraper ring 1704 are symmetrically connected with the return spring 1705, and the other end of the return spring 1705 is connected to the shaft of the fan wheel 1702, and the scraper ring 1704 is elastically connected to the fan wheel 1702 through the return spring 1705, and the scraper ring 1704 is slidably connected to the fan blade of the fan wheel 1702;

[0032] The specific operation is as follows. After the smoke is cooled, it enters the air outlet hood 1701 from the coil 202 through the connecting pipe 204. The fan wheel 1702 rotates in the air outlet hood 1701 under the blowing of the smoke, thereby breaking up the smoke and reducing its speed, so that it is evenly dispersed from the air outlet hood 1701 to the dust removal box 6, thereby enhancing the dust removal effect on the smoke. When the smoke drives the fan wheel 1702 to rotate, the scraper ring 1704 will slide on the surface of the fan blade under the action of centrifugal force and stretch the reset spring 1705. Different smoke flow rates will generate different centrifugal forces, and the moving distances of the scraper ring 1704 will be different, so that the scraper ring 1704 will be moved on the fan blade under the action of the reset spring 1705.

When the cleaning device is in operation, hot water enters the air outlet hood 1701 from the coil 202 through the connecting pipe 204, and can also flush the fan wheel 1702 and drive the fan wheel 1702 to rotate. The power of the flushing pump 208 can be adjusted to adjust the hot water flow rate, so that the scraper ring 1704 can fully clean the fan blades to avoid dust adhesion and accumulation. In summary, when in use, the smoke can be dispersed and slowed down to enhance the dust removal effect on the smoke, and the fan blades can be cleaned. Cleaning, after the flue gas enters the dust removal box 6, the outlet pump 4 draws the circulating water in the water tank 3 into the annular pipe 5 and sprays it into the dust removal box 6, so as to settle the dust in the flue gas and neutralize the flue gas. After the dust falls, it is intercepted by the sieve plate 10. At the same time, the sieve plate 10 exerts force on the vibration spring 9 under the impact of water and dust, so that the vibration spring 9 drives the sieve plate 10 to vibrate repeatedly in the vibration chamber 7, so that the trapped dust slides along the inclined surface of the sieve plate 10 and leaves the dust removal box 6 from the dust removal port 8, and the water can pass through the sieve plate 10 to reach the lower part of the dust removal box 6, and is drawn into the cooling box 201 by the return water pump 209 to supplement the circulating water in the cooling box 201. The flue gas with dust removed continues to rise, and the activated carbon plate 1 6 can absorb the residual dust and odor in the flue gas, and the purified flue gas leaves the dust removal box 6 and is discharged into the outside. As the amount of material absorbed by the activated carbon plate 16 increases, its weight also increases, and the support spring 14 can be compressed through the bottom plate 15. The pressure sensor monitors the force applied to the support spring 14. When the force applied to the support spring 14 reaches a predetermined value, the adsorption amount of the activated carbon plate 16 reaches a limit. At this time, the bottom frame 12 can be pulled out of the mounting groove 11, and the activated carbon plate 16 can be replaced to ensure the purification effect. In summary, during use, the dust can be automatically discharged, and the adsorption state of the activated carbon plate 16 can be monitored to facilitate its replacement.

[0033] In summary, when the high-temperature flue gas dust removal device for lithium ore roasting is used, first, the flue gas can enter the coil 202 from the three-way valve 210 through an air inlet pipe 203, and the circulating water in the cooling box 201 can absorb the heat of the flue gas through the coil 202 to cool it down, thereby preventing the high-temperature flue gas from directly contacting the dust removal structure and reducing its service life. After absorbing the heat, the circulating water forms steam and evaporates. After contacting the lower surface of the guide plate 206, it releases heat and condenses on the lower surface of the guide plate 206, thereby preheating the material to be processed through the guide plate 206, and recovering the heat of the high-temperature flue gas for processing. The condensed droplets can slide along the inclined surface of the guide plate 206 under the restriction of the guide plate 205 and enter the temporary storage box 207, and The smoke flows back into the water tank 3 through the pipe. After the smoke is cooled, it enters the air outlet hood 1701 from the coil 202 through the connecting pipe 204. The fan wheel 1702 rotates in the air outlet hood 1701 under the blowing of the smoke, thereby breaking up the smoke and reducing its speed, so that it is evenly dispersed from the air outlet hood 1701 to the dust removal box 6, thereby enhancing the dust removal effect on the smoke. When the smoke drives the fan wheel 1702 to rotate, the scraper ring 1704 will slide on the surface of the fan blade under the action of centrifugal force and stretch the reset spring 1705. Different smoke flow rates will generate different centrifugal forces, and the moving distance of the scraper ring 1704 will be different, so that the scraper ring 1704 moves back and forth on the fan blade under the action of the reset spring 1705, cleans the surface of the fan blade, and prevents adhesion. The strong dust leaves the air outlet hood 1701 together with the flue gas, and the limit plate 1703 can prevent the scraper ring 1704 from falling off the fan blade when the centrifugal force is too strong. After the flue gas enters the dust removal box 6, the outlet pump 4 draws the circulating water in the water tank 3 into the ring pipe 5 and sprays it into the dust removal box 6 to settle the dust in the flue gas and neutralize the flue gas. After the dust falls, it is intercepted by the sieve plate 10. At the same time, the sieve plate 10 exerts force on the vibration spring 9 under the impact of water and dust, so that the vibration spring 9 drives the sieve plate 10 to vibrate repeatedly in the vibration chamber 7, so that the trapped dust slides along the inclined surface of the sieve plate 10 and leaves the dust removal box 6 from the dust removal port 8, and the water can reach the lower part of the dust removal box 6 through the sieve plate 10 and is drawn into the cooling box 201 by the return water pump 209 to cool the cooling box 2 01 is replenished with circulating water, and the flue gas with dust removed continues to rise. The activated carbon plate 16 can absorb the residual dust and odor in the flue gas, and the purified flue gas leaves the dust removal box 6 and is discharged into the outside. As the amount of material absorbed by the activated carbon plate 16 increases, its weight also increases, and the support spring 14 can be compressed through the bottom plate 15. The pressure sensor monitors the force of the support spring 14. When the force of the support spring 14 reaches a predetermined value, the adsorption amount of the activated carbon plate 16 reaches the limit. At this time, the bottom frame 12 can be pulled out of the installation groove 11, and the activated carbon plate 16 can be replaced to ensure the purification effect. When the device needs to be cleaned, the passage can be changed through the three-way valve 210 to allow the flue gas to enter another intake pipe 203.Then, the hot water in the cooling box 201 is pumped out by the flushing pump 208 and sent into the air inlet pipe 203, so as to flush the air inlet pipe 203 and the coil 202, and wash away the dust adhering to the inner wall of the pipe to avoid the pipe being blocked by dust accumulation. After the hot water enters the air outlet cover 1701 from the coil 202 through the connecting pipe 204, it can also flush the impeller 1702 and drive the impeller 1702 to rotate. By adjusting the power of the flushing pump 208, the hot water flow rate can be controlled, so that the scraper ring 1704 can fully clean the fan blades to avoid dust adhesion and accumulation.
