Description

Technical Field

[0001] The invention relates to the technical field of petroleum coke flue gas treatment, and in particular to a petroleum coke calcining cooling flue gas treatment device. 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 petroleum coke calcination and cooling flue gas treatment device is an indispensable environmental protection equipment in the petroleum coke calcination process. It is mainly used to treat the high-temperature flue gas generated during the calcination process. Petroleum coke calcination is to heat the petroleum coke at a high temperature of 1200℃-1400℃ to remove volatiles, moisture and other impurities, thereby increasing its fixed carbon content and electrical conductivity, making it more suitable for aluminum electrolysis, steel smelting, carbon products and other industries. However, this process will produce a large amount of high-temperature flue gas, which contains pollutants such as dust, sulfide, nitrogen oxides, carbon monoxide, etc. If it is directly discharged without treatment, it will cause serious harm to the atmospheric environment, ecosystem and human health.

[0003] The common petroleum coke calcining cooling flue gas treatment device cannot automatically adjust the spray parameters according to the flue gas flow rate when treating petroleum coke calcining cooling flue gas with different flow rates. The spray 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, the spray water cannot be concentrated to improve the spray dust removal effect of 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 the spray range of the spray water cannot be increased, resulting in incomplete dust removal of the flue gas. At the same time, petroleum coke flue gas contains sticky substances and high-temperature particles. These substances are easy to adhere to the surface of the filter material, resulting in clogging of the pores of the filter material and increased filtration resistance. After running for a period of time, a thick dust layer will form on the surface of the filter material, which will not only affect the filtration efficiency, but also increase the energy consumption of the equipment, and require frequent cleaning operations. Frequent cleaning will shorten the service life of the filter material and increase the equipment maintenance cost. Therefore, corresponding treatment measures are required. Summary of the invention

[0013] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: 1. The present invention provides a flow rate adaptive component so that the device can automatically adjust the rotation speed of multiple No. 1 sprinkler heads and the spraying mode of the device according to the change of the flue gas flow rate. When the flue gas flows into the air inlet pipe, the flow rate of the flue gas will affect the current of the motor, thereby enabling the rotation speed of the motor to be adaptively adjusted. The rotation speed of the motor is adjusted to complete the adjustment of the rotation speed of multiple No. 1 sprinkler heads. When the flue gas flow rate is low, the flue gas flowing into the tower body is relatively small. At this time, the rotation speed of the No. 1 sprinkler head is low, so that the spray water is relatively concentrated, which is beneficial to improving the spraying effect. When the flue gas flow rate is high, the flue gas flowing into the tower body is relatively large. At this time, the rotation speed of the No. 1 sprinkler head is increased to increase the spray range, thereby ensuring the treatment effect of the device.

[0014] 2. The present invention provides a spray assembly that cooperates with a flow rate adaptive assembly to spray and wash the flue gas more comprehensively and evenly. The rotary spraying of the No. 1 spray head can expand the spraying range and make the spray water more evenly distributed in the treatment tower body. The auxiliary spraying of the No. 2 spray head at a high flow rate further enhances the treatment effect and effectively removes dust and harmful gases in the flue gas.

[0015] 3. The present invention uses the power of the spray component to operate the subsequent multiple cleaning components through the transmission component, so that the two can achieve closer coordinated operation. When the spray component starts working, the cleaning component will also start synchronously, which is more in line with actual use needs and can also make energy utilization more efficient, thereby helping to reduce the operating cost of the device.

[0016] 4. The cleaning component provided in the present invention can ensure the long-term stable operation of the device. With the continuous rotation of the transmission rod, the cleaning rod installed on its side wall makes a circular motion along the upper surface of the partition. During the cleaning process, the bottom of the cleaning rod fits tightly with the filter holes on the partition, which can effectively remove dust and other impurities attached to the surface of the filter holes and the surrounding areas, thereby avoiding the decrease in filtration efficiency due to blockage of the filter holes, and ensuring that the device can always maintain high-efficiency filtration performance during long-term operation. At the same time, when multiple cleaning components are working, they can also automatically accumulate the filtered dust in the collection area on the partition, making subsequent cleaning more convenient and more in line with actual usage needs.

The bottom surfaces of the multiple cleaning rods 51 are all in contact with the upper surface of the partition 2, so that the multiple cleaning rods 51 can play a normal cleaning role.

[0023] The working principle of the present invention is as follows: during treatment, the flue gas generated by the calcination and cooling of petroleum coke enters the treatment tower body 1 through the air inlet pipe 7. When the flue gas flows in the air inlet pipe 7, it drives the power plate 10 to rotate, thereby driving the No. 1 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. The counterweight block 14 is close to the center position of the circular plate 11 under the action of the No. 1 spring 15. The position of the conductive ring 18 on the variable resistance rod 17 makes the circuit resistance larger. The motor 23 runs at a lower speed. When the motor 23 runs, it drives the No. 2 rotating shaft 24 to rotate. The No. 2 rotating shaft The rotation of the worm 24 drives the worm 28 to rotate, and then drives the No. 1 water tank 26 and the worm wheel 27 to rotate through the meshing transmission. When the No. 1 water tank 26 rotates, it will drive multiple No. 1 spray heads 31 to perform circular motion, so that the No. 1 spray heads 31 can achieve rotary spraying, so that the spray water is more evenly distributed in the treatment tower body 1. When the flue gas flow rate is low, the flue gas flowing into the treatment tower body 1 is relatively small. At this time, the low speed method is more conducive to improving the spray dust removal effect, because the spray water will be relatively concentrated. When the flue gas flow rate increases, the counterweight block 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, the speed of the motor 23 is increased, the spraying speed of the No. 1 spray head 31 is accelerated, the flue gas flow rate is increased, and the flue gas flowing into the treatment tower body 1 will also increase. The spraying range of a single No. 1 spray head 31 is fan-shaped. When the flue gas flows in more, a treatment dead corner is likely to appear in the treatment tower body 1. At this time, the speed of the No. 1 spray head 31 should be increased to expand the treatment range of the spray water and ensure the treatment effect of the device. What needs to be noted here is that the speed of the No. 1 spray head 31 cannot be increased blindly, because when the speed of the No. 1 spray head 31 is too large, the spray water distribution will be too dispersed due to the action of centrifugal force, and the spray water in the middle position will be reduced, affecting The spraying effect is affected, so when the flue gas flow rate reaches a level that will affect the flue gas spraying effect, additional processing methods need to be added to cooperate with the use to ensure the overall processing effect of the device. When the flue gas flow rate reaches a certain level, the counterweight block 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, so that multiple solenoid valves 35 are opened, and the second spray head 36 starts spraying. By adding additional spraying methods to enhance the flue gas treatment effect, no manual adjustment is required. The rotation speed of multiple No. 1 spray heads 31 and the spraying method of the device are automatically adjusted by using the change of the flue gas flow rate, which is more in line with actual usage scenarios and needs. The smoke treated by spraying is discharged from the treatment tower body 1 through the exhaust pipe 8, and the spray water treated by spraying will fall onto the partition 2 under the influence of its own weight and be filtered by the filter hole 5, so that the dust remains on the upper surface of the partition 2, and the filtered spray water is discharged through the No. 3 water outlet pipe 54, and can be reused after subsequent purification treatment. When the spray component is in operation, the rotation of the No. 2 rotating shaft 24 will drive the driving wheel 38 to rotate, and the driven wheel 39 and the No. 3 rotating shaft 37 will rotate through the transmission of the belt 40. The rotation of the No. 3 rotating shaft 37 drives the No. 1 bevel gear 43 to rotate, and the No. 2 bevel gear 44, the No. 4 rotating shaft 41 and the transmission rod 42 are driven to rotate through the meshing transmission. When the transmission rod 42 rotates, the cleaning rod 51 of the cleaning component will move on the upper surface of the partition 2. During the cleaning process, the bottom of the cleaning rod 51 is in contact with the filter on the partition 2. The hole 5 fits tightly, which can effectively remove dust and other impurities attached to the surface and periphery of the filter hole 5. When the cleaning rod 51 passes through the lifting pad 6, the slide bar 47 will slide upward, compressing the No. 2 spring 50. After passing over the lifting pad 6, under the elastic force of the No. 2 spring 50, the cleaning rod 51 fits with the upper surface of the partition 2 again to clean the filter hole 5 to prevent the filter hole 5 from being blocked. In this process, multiple cleaning rods 51 will divide the partition 2 into two areas through this periodic movement. In the filtering area 3, multiple cleaning rods 51 all fit the partition 2 and move to scrape off the accumulated dust on its surface. When the cleaning rod 51 moves to the collecting area 4, it is lifted up by the lifting pad 6, so that the scraped dust is accumulated in the collecting area 4. In this way, the subsequent cleaning operation of the partition 2 is simplified, and the operation of the device is made more efficient.
