[0002] The vacuum tail gas treatment device for crude anthracene negative pressure distillation is a tail gas treatment system designed specifically for the anthracene oil processing industry. It is designed to solve the environmental protection problem of tail gas emissions during the vacuum distillation of crude anthracene. The device absorbs and fixes harmful substances in the tail gas in the washing oil by spraying washing oil, thereby removing harmful substances in the tail gas and making the tail gas meet environmental emission standards.

At this time, the steam will pass The washed oil passes through the steam pipe 16 and enters the drum 15 to contact the wash oil with impurities, so that the wash oil with impurities reacts with the steam, and the harmful substances are lost. The steam is discharged from the exhaust pipe 19, so that the wash oil and the harmful substances are separated, and then the washed oil after the reaction is transported to the box body 1 through another second pump body 17 for the second tail gas treatment, so that the device can be recycled, thereby reducing the waste of resources, and making the device more convenient and efficient to use, and there is no need to frequently replace the wash oil, which reduces the workload of the staff, and when the rotating shaft 10 rotates, because the top of the outer wall of the rotating rod 20 and the outer side wall of the rotating shaft 10 are fixedly connected with the first sprocket 21, and a pair of first sprockets 21 are connected by a first chain 22,When the rotating shaft 10 rotates, the rotating rod 20 is driven to rotate through the first sprocket 21 and the first chain 22, so that the rotation of the rotating rod 20 drives the stirring plate 23 to rotate. When the washing oil contacts with the steam to react, the rotation of the stirring plate 23 can stir the washing oil, so that the washing oil can better contact with the steam, thereby not only making the washing oil better separated from the harmful substances, but also improving the efficiency and effect of separating the washing oil from the harmful substances, so that the overall working efficiency of the device is further improved, and when the rotating rod 20 rotates, the rotation of the rotating rod 20 will drive the pair of cleaning plates 28 to rotate, because the outer side walls of the pair of cleaning plates 28 are in contact with the inner side wall and the top of the inner wall of the barrel 15, the rotation of the cleaning plates 28 can The cleaning of the residual washing oil and the residual harmful substances on the end not only reduces the waste of washing oil, but also enables the residual harmful substances to be discharged from the drum 15 again through steam under the cleaning of the cleaning plate 28, thereby ensuring the working environment inside the drum 15, and when the cleaning plate 28 rotates, the rotation of the cleaning plate 28 will drive the auxiliary plate 30 to rotate through the third rotating rod 29, so that the auxiliary plate 30 cooperates with the rotation of the stirring plate 23, so that the washing oil can be more fully in contact with the steam, thereby further improving the purification efficiency of the washing oil, and also further improving the purification effect of the washing oil, so that the quality of the washing oil is guaranteed, so that the purified washing oil can better purify the exhaust gas, and when the rotating rod 20 rotates, the rotation of the rotating rod 20 drives the third gear 24 to rotate, so A pair of fourth gears 26 are meshed with the third gear 24, so that when the third gear 24 rotates, it drives the pair of fourth gears 26 to rotate, so that the rotation of the pair of fourth gears 26 drives the pair of first rotating rods 25 to rotate, and the first rotating rods 25 drive the suction fan blades 27 to rotate, so that when harmful substances are discharged through the exhaust pipe 19 along with the steam, the steam and harmful substances can be discharged faster through the rotation of the suction fan blades 27, and when the suction fan blades 27 rotate to suck air, the steam will be guided so that the steam enters the exhaust pipe 19 along the flow of wind, so that the steam and harmful substances are not easy to contact the inner wall of the barrel 15 too much, thereby reducing the residual harmful substances in the barrel 15. When the cleaning plate 28 rotates, the rotation of the cleaning plate 28 will drive the first gear 26 to rotate. The fourth rotating rod 34 and the fifth gear 35 rotate around the center of the rotating rod 20. Because the fifth gear 35 is meshed with the gear groove 33, when the fifth gear 35 rotates around the center of the rotating rod 20, it will move along a group of gear grooves 33 while rotating, so that the rotation of the fifth gear 35 drives the third rotating rod 29 to rotate. Because the outer side walls of one end of the third rotating rod 29 and the fourth rotating rod 34 located in the square groove 31 are fixedly connected with the second sprocket 36, and a pair of second sprockets 36 are connected by a second chain 37, when the fourth rotating rod 34 rotates, the third rotating rod 29 will be driven to rotate through the second sprocket 36 and the second chain 37, so that the rotation of the third rotating rod 29 drives a group of auxiliary plates 30 to rotate, so that the rotation of the auxiliary plates 30 cooperates with the rotation of the stirring plates 23.The device can stir the wash oil in multiple directions, and because the stirring planes of the stirring plate 23 and the auxiliary plate 30 are different, when the stirring plate 23 and the auxiliary plate 30 cooperate to stir, the stirring effect and efficiency are further improved. The second sprocket 36 and the second chain 37 are located in the square groove 31, and the fifth gear 35 and the gear groove 33 are located at the high position of the barrel 15, so that the linkage mechanism in the device is hidden or in a place where the wash oil is not easily touched, which can not only reduce the waste of the wash oil, but also make the linkage mechanism in the device not easy to be damaged. When the exhaust gas purification is completed, the purified exhaust gas can be discharged by opening the valve at the exhaust pipe 3, so that the device can not only be recycled, but also more convenient, and the purification of the exhaust gas and the wash oil is integrated, so that the purification efficiency and effect of the exhaust gas are better.
