Description

Technical Field

[0001] The present invention relates to the field of environmental protection emissions of flue gas, and particularly to a lime slurry purification device for flue gas deacidification. Background Art

[0002] Flue gas is one of the common sources of air pollution. For example, a large amount of flue gas is generated during industrial production, energy and waste treatment processes, and such flue gas contains many harmful gases. Direct emission will seriously harm the environment. Existing flue gas needs to be subjected to a series of treatments before emission to ensure environmental protection during emission; a series of operations include flue gas deacidification. The commonly used method is to spray lime slurry through a spray head to contact the flue gas for deacidification; however, there are still certain deficiencies in the use of existing deacidification equipment: the positions of the spray head and the flue gas inlet end are constant, but during the generation of flue gas, the flow rate of the flue gas often fluctuates within a certain normal range, resulting in different speeds when the flue gas enters. Existing deacidification equipment cannot well adaptively adjust according to the flow rate fluctuation, and the deacidification effect needs to be improved. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems raised in the background art, and to propose a lime slurry purification device for flue gas deacidification.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A lime slurry purification device for flue gas deacidification, including a purification cylinder, an inlet slurry pipeline seat is installed on the purification cylinder, and a plurality of atomizing nozzles are rotatably installed on the inlet slurry pipeline seat through elastic telescopic members;

[0006] A rotating frame is rotatably installed on the purification cylinder with damping, a control self-rotation member is arranged between the rotating frame and the plurality of atomizing nozzles, a rotating ring cooperating with the inlet slurry pipeline seat is rotatably installed in the rotating frame with damping, a rotating ring is rotatably installed in the rotating frame with damping, and a control operation member is installed between the purification cylinder and the rotating frame and the rotating ring;

[0007] A second toothed ring is rotatably installed on the purification cylinder, a plurality of racks meshing with the second toothed ring are slidably installed on the purification cylinder, a moving rod frame is fixedly installed on each rack, and a cooperating operation member is installed between the control operation member and the moving rod frame;

[0008] An air inlet pipe and a distribution pipe are fixedly installed on the purification cylinder, a plurality of branch pipes are fixedly connected between the distribution pipe and the purification cylinder, a plurality of air inlet operation members are installed between the air inlet pipe and the distribution pipe, and the moving rod frame cooperates with the corresponding one.

[0009] Compared with the existing technology, the advantages of the present invention are:

[0010] 1: The state and position of the atomizing nozzle can be adaptively adjusted according to the change of the flue gas flow rate, so that the acid removal treatment of the flue gas can be carried out more quickly and effectively, and the environment can be better protected.

[0011] 2: The centrifugal force received by the atomizing nozzle when it revolves relative to the main slurry inlet pipe is less than the centrifugal force received when it rotates. When the centrifugal force increases, the atomizing nozzle can be adjusted to move down a certain extent relative to the slurry distribution seat, and the change of the centrifugal force is adapted to the flow rate of the flue gas. When the flow rate of the flue gas increases and the flow velocity increases, the atomizing nozzle can move down within a certain range to reduce the distance between the two, improving the purification effect.

[0012] 3: By cooperating with the operating components, the position of the moving rod frame can be automatically adjusted when the flue gas flow rate changes, and then the rotation of the rotating frame can be controlled separately, or the rotation of the rotating frame and the rotating ring can be controlled simultaneously, so as to automatically adjust the atomizing nozzle to revolve or rotate separately, which is convenient for better and effective acid removal of the flue gas.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0033] Referring to Figures 1 - 18 , a lime slurry purification device for flue gas deacidification, including a purification cylinder 1. The upper part of the purification cylinder 1 is fixedly communicated with an air outlet pipe (not shown in the figure) for conveying the purified flue gas to the next process. The purification cylinder 1 is provided with a slurry inlet pipe seat for injecting lime slurry into the purification cylinder 1. The lime slurry needs to be stirred before entering to ensure the uniformity of the concentration when the lime slurry enters. The slurry inlet pipe seat includes a slurry inlet pipe seat 2, a slurry distribution pipe seat 3, and a slurry distribution seat 4. The purification cylinder 1 is fixedly communicated with a slurry inlet pipe seat 2. A plurality of slurry distribution pipe seats 3 are fixedly communicated with the part of the slurry inlet pipe seat 2 located inside the purification cylinder 1. Each slurry distribution pipe seat 3 is rotationally and sealingly communicated with a slurry distribution seat 4, and the rotating ring 11 is fixedly arranged with the outermost slurry distribution seat 4. More specifically, the slurry inlet pipe seat 2 includes a main slurry inlet pipe and a circular slurry distribution seat. The purification cylinder 1 is fixedly communicated with a main slurry inlet pipe. The lower end of the main slurry inlet pipe is located inside the purification cylinder 1 and is fixedly communicated with a circular slurry distribution seat. More specifically, the slurry distribution pipe seat 3 includes a plurality of connecting slurry pipes and an annular slurry discharging seat. A plurality of connecting slurry pipes are fixedly communicated with the circular slurry distribution seat. The corresponding plurality of connecting slurry pipes are jointly fixedly communicated with an annular slurry discharging seat, and the annular slurry discharging seat is rotationally communicated with the slurry distribution seat 4. A plurality of fixing rods 28 are fixedly installed between adjacent slurry distribution seats 4.

[0034] A plurality of atomizing nozzles 6 are installed on the slurry inlet pipe seat through elastic telescopic members. Specifically, the atomizing nozzles 6 are installed on the corresponding slurry distribution seats 4. The plurality of atomizing nozzles 6 are rotationally arranged relative to the slurry inlet pipe seat. At the same time, with the arrangement of the elastic telescopic members, when their rotation speeds are different, their positions can be adjusted to a certain extent. Specifically, the centrifugal force received by the atomizing nozzle 6 when it revolves around the main slurry inlet pipe is less than the centrifugal force received by the atomizing nozzle 6 when it rotates. When the centrifugal force increases, the atomizing nozzle 6 can be adjusted downward by a certain amplitude relative to the slurry distribution seat 4, and the change of the centrifugal force is adapted to the flow rate of the flue gas. When the flue gas flow rate increases and the flow velocity increases, the atomizing nozzle 6 can move downward, and within a certain range, the distance between the two is reduced to improve the purification effect.

[0035] The elastic telescopic member includes a connecting pipe 5 and a first elastic telescopic rod 7. A plurality of connecting pipes 5 are rotatably communicated with each slurry dividing seat 4. The connecting pipe 5 includes a hard pipe and an elastic pipe. A plurality of hard pipes are rotatably communicated with the slurry dividing seat 4, and an elastic pipe is fixedly communicated between the hard pipe and the corresponding atomizing nozzle 6. The lower end of each connecting pipe 5 is fixedly communicated with the corresponding atomizing nozzle 6, and an elastic member is installed between the connecting pipe 5 and the corresponding atomizing nozzle 6. The elastic member includes a disc and a first elastic telescopic rod 7. A disc is fixedly sleeved on each connecting pipe 5, and a plurality of first elastic telescopic rods 7 are fixedly installed between each disc and the corresponding atomizing nozzle 6.

[0036] Refer to Figures 1 - 18 , a rotating frame 8 is damping rotatably installed on the purification cylinder 1. The rotating frame 8 includes a first annular body, a second annular body, a first connecting rod, a support rod. The first annular body is damping rotatably installed in the purification cylinder 1. The first annular body fixedly installs a second annular body through a plurality of first connecting rods. A support rod is fixedly installed in the annular body. The support rod includes a cross-shaped rod frame and a vertical rod. A cross-shaped rod frame is fixedly installed in the second annular body, and the middle of the cross-shaped rod frame is provided with an arc-shaped protrusion. A plurality of vertical rods are fixedly arranged on the cross-shaped rod frame. A control self-rotation member is arranged between the rotating frame 8 and the plurality of atomizing nozzles 6. The control self-rotation member includes a first toothed ring 9 and a first gear 10. A plurality of first toothed rings 9 are fixedly installed on the rotating frame 8. A first gear 10 is fixedly installed on each connecting pipe 5, and the first gear 10 meshes with the corresponding first toothed ring 9. The support rod is fixedly arranged with the plurality of first toothed rings 9, and the upper end of the vertical rod is fixedly arranged with the lower surface of the corresponding first toothed ring 9. The atomizing nozzles 6 are integrally distributed in a plurality of circles. One of the adjacent two first toothed rings 9 is provided with external teeth, and the other is provided with internal teeth. The purpose of this setting is to make the corresponding atomizing nozzles 6 rotate in opposite directions when rotating. The corresponding atomizing nozzles 6 here refer to the two atomizing nozzles 6 on the adjacent circular distributions. The purpose of this part of the setting is to make the atomizing nozzles 6 at different circular distributions better contact when atomizing and spraying lime slurry. When the atomizing nozzles 6 are set, to ensure repeated spraying, there is an overlapping part between the spraying areas of each other. By rotating, the overlapping part can better collide when contacting, increasing the contact effect with the flue gas and improving the deacidification effect.

[0037] Refer to Figures 1 - 18, a rotating ring 11 that is damped and rotates inside the rotating frame 8 and cooperates with the slurry inlet pipeline seat is provided. A control operation component is installed between the purification cylinder 1, the rotating frame 8, and the rotating ring 11. The damping rotation between the rotating frame 8, the purification cylinder 1, and the rotating ring 11 can effectively improve. When the rotating frame 8 or the rotating ring 11 is not subjected to a large external force, it will not move easily, improving the stability during use. The control operation component includes a clamping groove 12, a clamping frame 13, an internal gear ring 14, a motor 15, and a second gear 16. A plurality of clamping grooves 12 are provided on both the annular body one and the rotating ring 11. An internal gear ring 14 is rotatably installed inside the purification cylinder 1. A plurality of clamping frames 13 that cooperate with the clamping grooves 12 are slidably installed on the lower surface of the internal gear ring 14. More specifically, a stepped chute is provided on the lower surface of the internal gear ring 14, and the upper end of the clamping frame 13 is slidably arranged in the stepped chute. The clamping frame 13 can move relative to the internal gear ring 14, but when the internal gear ring 14 rotates, it will also drive the clamping frame 13 to rotate together. A motor 15 is fixedly installed on the top wall of the purification cylinder 1, and a second gear 16 that meshes with the internal gear ring 14 is fixedly installed on the driving end of the motor 15. When the control operation component works, it can control the rotation of the rotating frame 8 alone or control the simultaneous rotation of the rotating frame 8 and the rotating ring 11. Specifically, under the comprehensive conditions of the flow rate and flow velocity of the flue gas, it automatically makes adaptive adjustments. When the pipeline size is constant, as the flue gas flow rate increases, the flow velocity increases.

[0038] Refer to Figures 1 - 18 , a second gear ring 20 is rotatably installed on the purification cylinder 1. A circular groove body is provided on the top wall of the purification cylinder 1, and the end face shape of the circular groove body is stepped. A plurality of limiting sliders two 19 are rotatably installed in the circular groove body, and the end face shape of the limiting sliders two 19 is also set to be stepped. The lower end of the limiting slider two 19 is fixedly arranged with the second gear ring 20. A plurality of racks 18 that mesh with the second gear ring 20 are slidably installed on the purification cylinder 1. A plurality of strip-shaped groove bodies are provided on the top wall of the purification cylinder 1, and the end face shape of the strip-shaped groove bodies is stepped. A limiting slider one 17 is slidably installed on each strip-shaped groove body. A plurality of round rods are fixedly arranged on the lower surface of the limiting slider one 17, and the round rods are fixedly arranged with the corresponding racks 18.

[0039] A moving rod holder 21 is fixedly installed on each rack 18, and a cooperating operating member is installed between the control operating member and the moving rod holder 21; the cooperating operating member includes an arc-shaped clamping rod 22 and an arc-shaped seat 23. A moving rod holder 21 is fixedly installed on each arc-shaped seat 23, and a stepped sliding groove is formed in the arc-shaped seat 23. An arc-shaped clamping rod 22 is fixedly installed on each clamping frame 13, and one end of the arc-shaped clamping rod 22 is slidably installed on the corresponding arc-shaped seat 23. The size of the arc-shaped clamping rod 22 is greater than the distance between two adjacent arc-shaped seats 23. During the rotation of the arc-shaped clamping rod 22, for part of the time, it is completely alone on one arc-shaped seat 23, and for the rest of the time, it is located on two adjacent arc-shaped seats 23. When the flue gas flow rate changes (a large change within the normal range), the position of the moving rod holder 21 can be automatically adjusted through the cooperating operating member, thereby separately controlling the rotation of the rotating frame 8, or simultaneously controlling the rotation of the rotating frame 8 and the rotating ring 11 together, so as to automatically adjust the atomizing nozzle 6 to rotate separately or rotate on its own axis, which is convenient for better effectively removing acid from the flue gas.

[0040] Referring to Figures 1 - 18 , an air inlet pipe 24 and a distribution pipe 29 are fixedly installed outside the purification cylinder 1. A plurality of branch pipes 30 are fixedly connected between the distribution pipe 29 and the purification cylinder 1. A plurality of air inlet operating members are installed between the air inlet pipe 24 and the distribution pipe 29, and the moving rod holder 21 is matched with the corresponding one; the air inlet operating member includes a first pipe, a second pipe, a regulating pipe 25, a stop block 26, and an elastic telescopic rod two 27. A plurality of first pipes are fixedly connected to the air inlet pipe 24, and a plurality of second pipes are fixedly connected to the distribution pipe 29. A regulating pipe 25 is fixedly connected between the first pipe and the corresponding second pipe. A stop block 26 is hermetically slidably installed in each regulating pipe 25. The connection between the first pipe and the corresponding regulating pipe 25 is perpendicular to the diameter direction of the stop block 26; the connection between the second pipe and the corresponding regulating pipe 25 is perpendicular to the thickness direction of the stop block 26; and a plurality of elastic telescopic rods two 27 are fixedly installed between the stop block 26 and the corresponding regulating pipe 25. The elastic telescopic rod two 27 is provided to drive the movement of the stop block 26 after the flue gas flow rate changes. However, it should be noted that when the stop block 26 is in the closest state to the first pipe, the stop block 26 does not completely block the connection between the second pipe and the regulating pipe 25; other structures or devices with the same function can also be used to replace the elastic telescopic rod two 27, and no specific description will be made here.

[0041] For the convenience of understanding the present invention, the specific usage process will be described here. It should be noted that this is only for convenient understanding, and the specific operation process and sequence can be adaptively adjusted according to requirements;

[0042] Atomization and spraying of lime slurry: The lime slurry is transported to the sub-slurry pipe seat 3 through the slurry inlet seat 2, then enters the sub-slurry seat 4, and then is transported to the atomizing nozzle 6 through the connecting pipe 5 and sprayed out through the atomizing nozzle 6;

[0043] The atomizing nozzle 6 rotates independently in a circle: At this time, the flue gas flow velocity is in a small or medium range within the normal range. At this time, the lower end of the engaging frame 13 is simultaneously located in the engaging grooves 12 on the rotating frame 8 and the rotating ring 11. The motor 15 is turned on. The motor 15 drives the internal gear ring 14 to rotate through the second gear 16. The rotation of the internal gear ring 14 drives the rotating ring 11 and the rotating frame 8 to rotate through the engaging frame 13. The rotation of the rotating ring 11 drives a plurality of pulp dividing seats 4 to rotate. The rotation of the pulp dividing seats 4 drives the atomizing nozzle 6 to rotate in a circle. At this time, the atomizing nozzle 6 is subjected to a certain centrifugal force and can move downward relative to the stationary state. It can also be set that under the state of rotating in a circle, the centrifugal force received by the atomizing nozzle 6 is less than the pulling force of the first elastic telescopic rod 7 and will not move downward;

[0044] The atomizing nozzle 6 rotates independently: At this time, the flue gas flow velocity is large. At this time, the engaging frame 13 can be completely located in the engaging groove 12 on the rotating frame 8. At this time, the rotating frame 8 rotates, the rotating ring 11 does not rotate, the rotation of the rotating frame 8 drives the first gear ring 9 to rotate, the rotation of the first gear ring 9 drives the first gear 10 to rotate, the rotation of the first gear 10 drives the connecting pipe 5 to rotate, and further drives the atomizing nozzle 6 to rotate;

[0045] Self-adjustment of the position of the engaging frame 13: The flue gas enters the control pipe 25 through the first pipe. When the flow velocity increases, the impact force on the stopper 26 increases, and then drives the moving rod frame 21 to move. The movement of the moving rod frame 21 drives the engaging frame 13 to move; at the same time, the movement of the moving rod frame 21 can also drive the rack 18 to move. With the cooperation of the second gear ring 20, the plurality of racks 18 move synchronously, and further ensure the precise synchronous movement of the plurality of moving rod frames 21.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
