Description

Technical Field

[0001] The present invention relates to the field of air pollution treatment equipment, in particular to a flue gas recovery device for a calcining furnace for producing petroleum coke products. Background Art

[0002] The flue gas from the calciner used to produce petroleum coke products is waste gas generated during the calcination of petroleum coke. It has a complex composition and contains a variety of pollutants, including particulate matter, sulfur dioxide, nitrogen oxides, and volatile organic compounds. The particulate matter mainly includes incompletely burned coke powder, raw material ash, and micron-sized carbon particles generated during the calcination process. The flue gas needs to undergo multiple steps of purification before it can be discharged into the air, otherwise it will cause atmospheric pollution. After pretreatment, the flue gas from the calcining furnace for producing petroleum coke products still contains particulate matter. In the prior art, a bag filter is used to filter the dust-laden flue gas to recover the particulate matter. The bag filter intercepts and adsorbs the particulate matter in the flue gas through the filter material, and can efficiently capture particulate matter of different particle sizes. It has a good capture effect on fine dust and other particulate matter remaining in the flue gas from the calcining furnace for producing petroleum coke products after pretreatment. The particulate matter is trapped on the surface of the filter bag, and the purified gas is discharged through the filter bag. The trapped particulate matter retains its original physical and chemical properties. In the prior art, during the backflushing process of the filter bags in the bag collector, after one backflushing, the particles or smoke attached to the surface of the filter bags can be scattered. As time goes by, more and more fine dust or particles accumulate on the surface of the filter bags, and the backflushing cleaning effect decreases. This is because the pores of the filter bags become smaller, which increases the resistance to airflow, making it difficult for the backflushing airflow to effectively penetrate the filter bags, affecting the cleaning effect.

[0003] Therefore, it is necessary to propose a flue gas recovery device for a calcining furnace for producing petroleum coke products to solve the above problems. Summary of the Invention

[0015] Compared with the prior art, the present invention provides a flue gas recovery device for a calcining furnace for producing petroleum coke products, which has the following beneficial effects: The flue gas recovery device of the calcining furnace for producing petroleum coke products is driven by a first motor to rotate a transmission column, and the cam and the second adjusting wheel both rotate with the rotation of the transmission column. The rotation of the second adjusting wheel drives the first adjusting wheel to rotate, and then drives the rotating column to rotate. The rotation angle is forty-five degrees.

[0016] The flue gas recovery device for a calcining furnace producing petroleum coke products can drive the second partition to rotate by rotating the rotating column, thereby dividing multiple filter bags inside the housing into four equal areas. When the second partition cooperates with the first partition, the filter bags in one area are separated from the entire device, allowing for independent inspection and maintenance without stopping the equipment, thereby ensuring the efficiency of recovering particulate matter in the flue gas. When the first partition cooperates with the second partition, during the backflushing of the filter bags, due to the barrier effect of the first and second partitions, the backflushing will not affect the flue gas filtration of the filter bags in the other three areas. In the flue gas recovery device of the calcining furnace for producing petroleum coke products, during the backflushing process of the filter bags, due to the elastic force of the first spring, the air between the pressure plate and the enclosure is gradually consumed, and the compression amount of the first spring gradually decreases. At the beginning of backflushing, the relatively high pressure can effectively overcome the adhesion of the dust layer on the surface of the filter bags, causing most of the dust to fall off. The gradual reduction in backflushing pressure can avoid excessive impact on the filter bags due to excessive pressure in the early stage of backflushing, thereby extending the service life of the filter bags.

[0020] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 14 、 Figure 15 、 Figure 16 ,and Figure 18 A flue gas recovery device for a calcining furnace for producing petroleum coke products comprises a shell 1, an air inlet 11 provided on the surface of the shell 1 near the bottom end, an air outlet 12 provided on the surface of the shell 1 near the top end, a discharge port provided at the bottom of the shell 1, a fixed plate 13 fixedly connected to the inner wall of the shell 1, and a plurality of filter bags 14 fixedly connected to the lower surface of the fixed plate 13. A mounting frame 15 is fixedly connected to the inner wall of the shell 1 above the fixed plate 13, and a movable box 2 is mounted on the inner side of the mounting frame 15. The top of the shell 1 and the middle of the surface of the fixed plate 13 rotate to form a plurality of filter bags 14. A rotating column 3 is connected, and a rotating plate 4 is fixedly connected to the surface of the rotating column 3 between the fixed plate 13 and the top of the shell 1. A slider 5 is slidably connected to the middle of the surface of the rotating plate 4. The slider 5 is rotatably connected to the top of the movable box 2. The top of the movable box 2 is fixedly connected to the air intake pipe 6 next to the slider 5. Through holes 7 are symmetrically opened on the top of the shell 1, one of the through holes 7 is connected to the air intake pipe 6, and a backflush pipe 8 is fixedly connected to the bottom of the movable box 2. A first baffle 9 is fixedly connected to the lower surface of the fixed plate 13, and a second baffle 10 is fixedly connected to the lower end of the surface of the rotating column 3; The outer side of the rotating column 3 is located above the bottom of the shell 1 and is fixedly connected to the rotating drum 301. An annular groove 302 is opened on the outer side of the rotating drum 301. A plurality of first protrusions 303 are mounted on the wall of the annular groove 302. The ends of the plurality of first protrusions 303 away from the annular groove 302 are fixedly connected to L-shaped columns 304. The ends of the surfaces of the plurality of L-shaped columns 304 away from the rotating drum 301 are equidistantly fixedly connected to cylinders 305. The surface of the cylinder 305 is slidably connected to a lifting sleeve 306. The upper end of the lifting sleeve 306 is fixedly connected to a first spring 307. The upper ends of the plurality of first springs 307 are fixedly connected to the L-shaped column 304. The lower ends of the plurality of lifting sleeves 306 are fixedly connected to a pressure plate 308. A surrounding plate 309 is fixedly connected to the upper surface of the top of the shell 1. The pressure plate 308 is mounted in cooperation with the surrounding plate 309. The upper end of the rotating column 3 is fixedly connected to a first adjusting wheel 311, and a second adjusting wheel 312 is mounted on the outer side of the first adjusting wheel 311. The top of the enclosure 309 is fixedly connected to a first motor 313, and the lower part of the second adjusting wheel 312 is fixedly connected to a transmission column 314. A cam 315 is fixedly connected to the surface of the transmission column 314, and a movable column 316 is mounted on the outer side of the cam 315. A connecting sleeve 317 is slidably connected to the end of the surface of the movable column 316 away from the cam 315. A connecting column 318 is slidably connected to the lower part of the connecting sleeve 317. The lower end of the connecting column 318 is fixedly connected to a connecting plate 310, and the connecting plate 310 is fixedly connected to the multiple lifting sleeves 306. It should be noted that the first motor 313 drives the transmission column 314 to rotate, which in turn drives the second adjusting wheel 312 to rotate. The second adjusting wheel 312 and the first adjusting wheel 311 form a groove wheel, which in turn drives the rotating column 3 to rotate. The second adjusting wheel 312 rotates one circle, and the rotating column 3 rotates forty-five degrees. The rotating drum 301 rotates as the rotating column 3 rotates, and the annular groove 302 can produce relative rotation with the first protruding column 303. Every forty-five degrees of rotation, the first protruding column 303 moves from the low point of the annular groove 302 to the high point or from the high point to the low point, and the L-shaped column 304 moves as the first protruding column 303 moves. In the process of the L-shaped column 304 moving toward the top of the shell 1, the air in the accommodating space formed between the pressure plate 308 and the enclosure 309 is compressed, and the cylinder 305 and the lifting sleeve 306 generates relative movement, the first spring 307 is compressed, the cam 315 rotates as the transmission column 314 rotates, the rotation of the cam 315 drives the movable column 316 to move, the second spring 3163 is compressed, and the inclined plate 3161 and the arc groove 3162 all generate relative movement with the connecting sleeve 317, so that the pressure plate 308 that is adjusted to be pressed down can move up and down multiple times. In this process, the first spring 307 is always in a compressed state, that is, in the process of the connecting sleeve 317 being adjusted to move up and down, it is still subjected to the reaction force generated by the compression of the first spring 307, so that the back-blowing pressure changes continuously, and the filter bag 14 can generate vibration, thereby ensuring the cleaning effect of particulate matter and smoke dust on the surface of the filter bag 14, so that the smoke can meet the emission standards, thereby avoiding causing air pollution; When the second partition 10 does not cooperate with the first partition 9 to separate the interior of the housing 1 into one area, the filter bag 14 inside the housing 1 can filter the smoke at the same time; During the back-flushing process of the filter bag 14, due to the elastic force of the first spring 307, the air between the pressure plate 308 and the enclosure 309 is gradually consumed, and the compression amount of the first spring 307 gradually decreases. At the beginning of back-flushing, the relatively high pressure can effectively overcome the adhesion of the dust layer on the surface of the filter bag 14, causing most of the dust to fall off. The gradual reduction of the back-flushing pressure can avoid excessive impact on the filter bag 14 caused by excessive pressure in the early stage of back-flushing, thereby extending the service life of the filter bag 14. It should be noted that an air intake valve can be installed on the surface of the through hole 7 to control the compressed air in the accommodating space formed by the enclosure 309, the pressure plate 308 and the top of the outer shell 1 to pass smoothly through the through hole 7, the air intake pipe 6 and the movable box 2, and finally back-blow the filter bag 14 through the back-blow pipe 8 to clean the dust, which is beneficial to the recovery of particulate matter and smoke dust in the flue gas.

[0021] It should be noted that, according to actual usage, the rotation of the rotating column 3 can be adjusted to divide the interior of the shell 1 into an area respectively, and the air inlet valve can be adjusted to open in turn to backflush the filter bag 14, or the interior space of the shell 1 can be kept unchanged.

[0022] See also Figure 3 and Figure 6 , the top upper surface of the housing 1 is fixedly connected to a plurality of columns 3041 located next to the rotating drum 301, and the columns 3041 are slidably connected to the L-shaped columns 304; It should be noted that the setting of the column 3041 can limit the movement of the L-shaped column 304 during the adjustment and movement process.

[0023] See also Figure 1 The surface of the enclosure 309 is symmetrically provided with an air inlet 3091 at one end close to the top of the housing 1, and a one-way valve is installed on the wall of the air inlet 3091; It should be noted that the setting of the one-way valve can ensure that air can enter the space formed between the enclosure 309 and the pressure plate 308 through the air inlet hole 3091 and exit through the air inlet pipe 6 and the through hole 7.

[0024] See also Figure 4 The end of the surface of the movable column 316 away from the cam 315 is fixedly connected to the inclined plate 3161, and the surface of the inclined plate 3161 is equidistantly provided with arc grooves 3162; It should be noted that the setting of the inclined plate 3161 and the arc groove 3162 enables the connecting sleeve 317 to move relative to the inclined plate 3161 and the arc groove 3162 during the adjustment and movement of the movable column 316, so that the pressure plate 308 that is adjusted to be pressed downward can move up and down, causing the backblowing pressure to fluctuate and the filter bag 14 to shake, thereby ensuring the cleaning effect of particulate matter and smoke dust on the surface of the filter bag 14.

[0025] See also Figure 3 , a second spring 3163 is sleeved on the outer side of the movable column 316, one end of the second spring 3163 is fixedly connected to the enclosure 309, and the other end of the second spring 3163 is fixedly connected to the movable column 316; It should be noted that the provision of the second spring 3163 can facilitate the resetting of the movable column 316, so that the movable column 316 can always be in contact with the cam 315 during the adjustment and movement process, thereby ensuring the stability of the movable column 316 during the adjustment and movement.

[0026] See also Figure 15 、 Figure 16 、、 Figure 17 and Figure 19The surface of the second partition 10 is provided with a plurality of rectangular holes 101, and the wall of the rectangular hole 101 is provided with a mounting groove 102. The wall of the mounting groove 102 is symmetrically fixedly connected with a third spring 103. The other ends of the two third springs 103 are fixedly connected with a baffle 104. The baffle 104 is slidably connected to the rectangular hole 101 and the mounting groove 102. It should be noted that, by utilizing the elastic force of the third spring 103, when the second partition 10 is adjusted and rotated together with the rotating column 3, the baffle 104 can be driven to move under the elastic force of the third spring 103, so that the hole set on the surface of the baffle 104 can overlap with the rectangular hole 101, thereby allowing smoke to pass through. Every time it rotates ninety degrees, the end of the baffle 104 away from the third spring 103 is first separated from the inner wall of the shell 1, and the compression amount of the third spring 103 gradually decreases, which can drive the baffle 104 to move, and the baffle 104 overlaps with the rectangular hole 101 and The mounting grooves 102 move relative to each other until the holes provided on the surface of the baffle 104 are connected to the rectangular hole 101 for the flow of smoke. Then, the two baffles 104 contact the inner wall of the housing 1 and move relative to each other. The baffle 104 moves in the direction of compressing the third spring 103. The holes on the surface of the baffle 104 are misaligned with the rectangular hole 101. The baffle 104 blocks the rectangular hole 101, separating the area isolated by the first baffle 9, the second baffle 10, and the movable box 2 from other areas, thereby facilitating backflushing of the filter bag 14 in this area. During the adjustment of the rotating column 3 and the second partition plate 10 , the baffle 104 or the second partition plate 10 will come into contact with the second protruding column 110 , so that smoke cannot enter the separated area.

[0027] A limiting groove 16 is provided on the surface of the housing 1 next to the air inlet 11. A movable plate 17 is slidably connected to the wall of the limiting groove 16. A circular hole 18 is provided on the surface of the movable plate 17. A fixing block 19 is fixedly connected to the top of the movable plate 17. A return spring is fixedly connected to the surface of the fixing block 19. The other end of the return spring is fixedly connected to the wall of the limiting groove 16. A second protrusion 110 is symmetrically fixedly connected to the surface of the movable plate 17 near the second partition 10. It should be noted that the setting of the movable plate 17 of the limiting groove 16 can adjust the smoke inlet position so that the smoke can be transported to two different areas. During the backblowing process, the filter bags 14 in the entire area can be isolated, and the backblowing process will not affect the smoke filtration of the filter bags 14 in other areas.

[0028] The side wall of the movable box 2 is equipped with a plurality of balls; It should be noted that the balls can contact the side of the movable box 2 to avoid contact wear between the movable box 2 and the mounting frame 15 during the adjustment and movement process.

[0029] See also Figure 9 A rectangular groove 71 is formed in the wall of the through hole 7, and a horizontal column 72 is symmetrically fixedly connected to the wall of the rectangular groove 71. A cylinder 73 is slidably connected to the surface of the horizontal column 72. A fourth spring 74 is sleeved on the outer side of the cylinder 73. A stopper 75 is fixedly connected to the end of the two cylinders 73 away from the horizontal column 72, and one of the stoppers 75 is mounted in conjunction with the intake pipe 6; It should be noted that the setting of the block 75 and the fourth spring 74 can ensure that when one of the through holes 7 cooperates with the air intake pipe 6, the other three through holes 7 can be blocked, and air is only taken in from one through hole 7, so that the air between the pressure plate 308 and the enclosure 309 can pass through the air intake pipe 6, the movable box 2 and the back-blowing pipe 8 to back-blow the filter bag 14 for dust removal. After the movable box 2 is adjusted and moved, it can automatically return to its initial state under the action of the elastic force of the fourth spring 74, that is, the block 75 blocks the through hole 7.

[0030] See also Figure 10 、 Figure 11 、 Figure 12 and Figure 13 , column grooves 41 are symmetrically opened on the surface of the rotating plate 4, and the wall of the column groove 41 is fixedly connected to the fifth spring 42, and the other ends of the two fifth springs 42 are fixedly connected to the rotating rod 43, and the rotating rod 43 is slidably connected to the two column grooves 41. A sixth spring is fixedly connected to the surface of the slider, and the end of the sixth spring away from the slider is fixedly connected to the rotating plate 4; It should be noted that, by utilizing the elastic force of the fifth spring 42, after the rotating plate 4 is adjusted and moved, the end of the rotating rod 43 away from the fifth spring 42 is in close contact with the inner wall of the outer shell 1, thereby ensuring the stability of the movable box 2 after adjustment. By utilizing the elastic force of the sixth spring, the movable box 2 can be adjusted and moved close to the inner side of the mounting frame 15.

[0031] It should be noted that a controller may be installed on the side of the housing 1 next to the air inlet 11 , the air inlet valve and the first motor 313 are electrically connected to the air inlet valve, and the controller is controlled by a computer.
