Description

Technical Field

[0001] The present invention relates to the technical field of petroleum coke flue gas treatment, and particularly to a device for treating the flue gas of petroleum coke calcination and cooling. Background Art

[0002] As an important industrial raw material, petroleum coke will release a large amount of flue gas containing various pollutants during the calcination and cooling process. The device for treating the flue gas of petroleum coke calcination and cooling is an indispensable environmental protection equipment in the petroleum coke calcination process, mainly used for treating the high-temperature flue gas generated during the calcination process. Petroleum coke calcination is to heat petroleum coke at a high temperature of 1200°C - 1400°C to remove volatile components, moisture and other impurities, thereby increasing its fixed carbon content and electrical conductivity, making it more suitable for industries such as aluminum electrolysis, steel smelting, and carbon products. However, this process will generate a large amount of high-temperature flue gas, which contains pollutants such as dust, sulfides, nitrogen oxides, and carbon monoxide. If directly discharged without treatment, it will cause serious harm to the atmospheric environment, ecological system and human health.

[0003] For common devices for treating the flue gas of petroleum coke calcination and cooling, when treating the flue gas of petroleum coke calcination and cooling with different flow rates, they cannot automatically adjust the spraying parameters according to the flue gas flow rate. The spraying water always sprays the flue gas within a fixed range. When the flue gas flow rate is low, the filling range of the flue gas in the treatment device is relatively small. At this time, it is impossible to concentrate the spraying water to improve the spraying dust removal effect on the flue gas. When the flue gas flow rate is too high, the filling range of the flue gas in the treatment device is relatively large, and it is impossible to increase the spraying range of the spraying water, resulting in incomplete dust removal of the flue gas. At the same time, the petroleum coke flue gas contains viscous substances and high-temperature particles, which are easily attached to the surface of the filter material, resulting in the blockage of the pores of the filter material, an increase in the filtration resistance. After running for a period of time, a thick dust accumulation layer will form on the surface of the filter material, which not only affects the filtration efficiency but also increases the energy consumption of the equipment, and requires frequent dust cleaning operations. Frequent dust cleaning will shorten the service life of the filter material and increase the equipment maintenance cost. Therefore, corresponding treatment measures are needed.

[0015] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art:

[0016] 1. Through the flow rate adaptive component provided by the present invention, the device can automatically adjust the rotation speed of multiple first spray heads and the spray mode of the device according to the change of the flue gas flow rate. When the flue gas surges into the intake pipe, the flow rate of the flue gas will affect the current of the motor, and then the rotation speed of the motor is adjusted adaptively. By adjusting the rotation speed of the motor, the rotation speed of multiple first spray heads is adjusted. When the flue gas flow rate is low, the amount of flue gas surging into the tower body is relatively small. At this time, the rotation speed of the first spray heads is low, making the spray water relatively concentrated, which is beneficial to improving the spray effect. When the flue gas flow rate is high, the amount of flue gas surging into the tower body is relatively large. At this time, by increasing the rotation speed of the first spray heads, the spray range is increased, thus ensuring the treatment effect of the device. At the same time, when the flue gas flow rate reaches a certain speed, an additional spray mode will be automatically added to improve the treatment effect, ensuring the stability and high efficiency of the device under different working conditions.

[0017] 2. Through the spray component provided by the present invention, in cooperation with the flow rate adaptive component, the flue gas can be sprayed and washed more comprehensively and evenly. The rotating spray of the first spray heads can expand the spray range and make the spray water more evenly distributed in the treatment tower body. The auxiliary spray of the second spray heads at high flow rates further enhances the treatment effect, effectively removing dust and harmful gases in the flue gas.

[0018] 3. Through the transmission component provided by the present invention, the power of the spray component is used to operate multiple subsequent cleaning components, enabling closer coordinated operation between the two. When the spray component starts to work, the cleaning components will also be started synchronously. While meeting the actual use requirements better, it can also make the energy utilization efficiency higher, thus helping to reduce the operating cost of the device.

[0019] 4. Through the cleaning component provided by the present invention, the long-term stable operation of the device can be ensured. As the transmission rod rotates continuously, the cleaning rod installed on its side wall makes a circular motion along the upper surface of the partition plate. During the cleaning process, the bottom of the cleaning rod is closely attached to the filter holes on the partition plate, which can effectively remove dust and other impurities attached to the surface and periphery of the filter holes, thus avoiding the decrease in filtration efficiency caused by the blockage of the filter holes. It ensures that the device can always maintain high filtration performance during long-term operation. At the same time, when multiple cleaning components are working, they can automatically accumulate the filtered dust in the collection area on the partition plate, making subsequent cleaning more convenient and more in line with the actual use requirements.

The inclined surface cooperates with the lifting pad 6. The bottom surfaces of multiple cleaning rods 51 are all in contact with the upper surface of the partition plate 2, enabling the multiple cleaning rods 51 to play a normal cleaning role.

[0036] The working principle of the present invention is as follows: During processing, the flue gas generated by the calcination and cooling of petroleum coke enters the treatment tower body 1 through the intake pipe 7. When the flue gas flows in the intake pipe 7, it drives the power plate 10 to rotate, thereby driving the first rotating shaft 9 and the circular plate 11 to rotate. According to the different flue gas flow rates, the rotation speed of the circular plate 11 is also different. When the flue gas flow rate is low, the centrifugal force generated by the rotation of the circular plate 11 is relatively small. Under the action of the first spring 15, the counterweight 14 approaches the center position of the circular plate 11. The position of the conductive ring 18 on the variable resistance rod 17 makes the circuit resistance relatively large, and the motor 23 operates at a relatively low speed. When the motor 23 operates, it drives the second rotating shaft 24 to rotate. The rotation of the second rotating shaft 24 drives the worm 28 to rotate, and then drives the first water storage tank 26 and the worm gear 27 to rotate through meshing transmission. When the first water storage tank 26 rotates, it drives a plurality of first spray heads 31 to perform circular motion, so that the first spray heads 31 achieve rotary spraying, making the sprayed water more evenly distributed in the treatment tower body 1. When the flue gas flow rate is small, the amount of flue gas flowing into the treatment tower body 1 is relatively small. At this time, the low-speed mode is more conducive to improving the spray dust removal effect because the sprayed water will be relatively concentrated. When the flue gas flow rate increases, the counterweight 14 slides outward along the guide rod 13 under the action of centrifugal force, driving the conductive ring 18 to slide on the variable resistance rod 17, reducing the circuit resistance, increasing the rotation speed of the motor 23, and accelerating the spraying speed of the first spray heads 31. As the flue gas flow rate increases, the amount of flue gas flowing into the treatment tower body 1 also increases. The spraying range of a single first spray head 31 is fan-shaped. When the inflowing flue gas increases, it is easy to have treatment dead spots in the treatment tower body 1. At this time, the rotation speed of the first spray heads 31 should be increased to expand the treatment range of the sprayed water and ensure the treatment effect of the device. It should be noted here that the rotation speed of the first spray heads 31 cannot be increased blindly because when the rotation speed of the first spray heads 31 is too high, the sprayed water will be too dispersed due to the action of centrifugal force, and the sprayed water in the middle position will decrease, affecting the spraying effect. Therefore, when the flue gas flow rate reaches a level that affects the spraying effect on the flue gas, additional treatment methods need to be used in combination to ensure the overall treatment effect of the device. When the flue gas flow rate reaches a certain level, the counterweight 14 reaches the set maximum threshold under the action of centrifugal force. At this time, the touch pressure plate 21 will trigger the touch pressure switch 22, causing a plurality of solenoid valves 35 to open, and the second spray heads 36 start to spray, enhancing the treatment effect on the flue gas by adding additional spraying methods. Without manual adjustment, the rotation speed of a plurality of first spray heads 31 and the spraying method of the device are automatically adjusted by means of the change in the flue gas flow rate, which is more in line with the actual use scenario and requirements;

[0037] The flue gas treated by spraying is discharged from the treatment tower body 1 through the outlet pipe 8. Under the influence of its own weight, the spraying water for spraying treatment will fall onto the partition plate 2 and be filtered by the filter holes 5, so that the dust remains on the upper surface of the partition plate 2. The filtered spraying water is discharged through the third outlet pipe 54 and can be reused after subsequent purification treatment. When the spraying assembly is operating, the rotation of the second rotating shaft 24 will drive the driving wheel 38 to rotate. Through the transmission of the belt 40, the driven wheel 39 and the third rotating shaft 37 are driven to rotate. The rotation of the third rotating shaft 37 drives the first bevel gear 43 to rotate. Through meshing transmission, the second bevel gear 44, the fourth rotating shaft 41 and the transmission rod 42 are driven to rotate. When the transmission rod 42 rotates, the cleaning rod 51 of the cleaning assembly will move on the upper surface of the partition plate 2. During the cleaning process, the bottom of the cleaning rod 51 is in close contact with the filter holes 5 on the partition plate 2, which can effectively remove dust and other impurities attached to the surface and periphery of the filter holes 5. When the cleaning rod 51 passes over the lifting pad 6, the sliding rod 47 will slide upward, compressing the second spring 50. After passing over the lifting pad 6, under the elastic force of the second spring 50, the cleaning rod 51 is in contact with the upper surface of the partition plate 2 again to clean the filter holes 5 and prevent the filter holes 5 from being blocked. During this process, through this periodic movement of multiple cleaning rods 51, the partition plate 2 is divided into two areas. In the filtering area 3, multiple cleaning rods 51 all move in contact with the partition plate 2 to scrape the accumulated dust on its surface. When the cleaning rod 51 moves to the collection area 4, it is lifted by the lifting pad 6, so that the scraped dust accumulates in the collection area 4. In this way, the subsequent cleaning operation of the partition plate 2 is simplified, making the device operate more efficiently.
