Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to a full-oxygen combustion glass melting furnace flue gas treatment device. Background Art

[0002] Glass melting furnaces use a mixture of natural gas and oxygen as fuel. The flue gas produced contains a variety of harmful substances such as dust, sulfur, and nitrogen oxides. Therefore, the flue gas needs to be treated before discharge. For the flue gas produced by the full oxygen combustion glass melting furnace, a wet process of desulfurization and denitrification is often used in which the absorbing liquid reacts with the flue gas. The flue gas is introduced from the bottom of the treatment tank, and the absorbing liquid is sprayed into the tank body. After the flue gas contacts the absorbing liquid, it is discharged from the top of the tank body.

[0003] Among them, the effect of desulfurization and denitrification is related to whether the absorption liquid is in sufficient contact with the flue gas. The existing treatment tank structure generally includes a tank body, which is provided with an air inlet, a liquid inlet, a liquid outlet and an air outlet. When treating flue gas, the air inlet is used to connect with the flue gas device to introduce flue gas into the bottom of the entire tank body, the liquid inlet is used to connect with the absorption liquid device to spray the absorption liquid into the entire tank body, and the liquid outlet is used to connect with the waste liquid collection device to collect the absorption liquid after the reaction. The flue gas is discharged from the air outlet after the reaction. However, there is the following problem: since the flue gas continuously rises from the bottom of the tank body during the whole process, the airflow formed by the flue gas itself is relatively large, which will affect the contact with the absorption liquid to a certain extent and affect the desulfurization and denitrification effects, and there are certain deficiencies when it is used.

[0004] Therefore, the present invention provides a full oxygen combustion glass melting furnace flue gas treatment device to solve the above problems. Summary of the invention

When the rotating rod rotates, the lifting tube is driven to rise and fall. When the lifting tube is lifted to the maximum position, it rotates with the rotating rod, and also includes a second elastic limiting mechanism for elastically limiting the second rotating plate. In the natural state, the second rotating plate remains stationary. When the push rod is inserted into the slot and rotates, it drives the second rotating plate to rotate.

[0009] Preferably, the first elastic limiting mechanism includes a fixed outer sleeve and a roller arranged in the outer sleeve, a first spring is provided between the roller and the outer sleeve, and the lifting tube is slidably arranged in the outer sleeve through the roller.

[0021] The following will refer to the attached Figures 1 to 8 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0022] A flue gas treatment device for an oxygen-fired glass melting furnace, as shown in the attached Figure 1 As shown, it includes a tank body 4, on which an air inlet 2, a liquid outlet 3, a liquid inlet 5 and an air outlet 6 are arranged from bottom to top. When in use, the air inlet 2 is used to connect with the flue gas device to introduce flue gas into the bottom of the entire tank body 4, the liquid inlet 5 is used to connect with the absorption liquid device to spray the absorption liquid into the entire tank body 4, the liquid outlet 3 is used to connect with the waste liquid collection device to collect the absorption liquid after the reaction, and the flue gas is discharged from the air outlet 6 after the reaction. This part is the existing technology and will not be described in detail here.

[0023] As attached Figure 2 , Figure 3As shown, an inner tank 401 is provided at the bottom of the tank body 4, and both the tank body 4 and the inner tank 401 are hollow cylinders. In this embodiment, the tank body 4 and the inner tank 401 are fixedly arranged on a base 1, and a cover 21 is provided at the bottom of the base 1, wherein the inner tank 401 is connected to the air inlet 2, and the space between the inner tank 401 and the tank body 4 is connected to the liquid outlet 3, and a liquid leakage plate 16 is provided between the top peripheral side of the inner tank 401 and the tank body 4, and a liquid leakage hole 15 is provided on the liquid leakage plate 16. The inner rotating plate is provided with a first rotating plate 13 and a second rotating plate 20, the first rotating plate 13 is closely attached to the upper part of the second rotating plate 20, and the first rotating plate 13 and the second rotating plate 20 are provided with matching vents. In this embodiment, there are four vents on each rotating plate, and the adjacent vents are 45° apart. Specifically, the first rotating plate 13 is provided with four first vents 14, and the second rotating plate 20 is provided with four second vents 19. When the first vents 14 and the second vents 19 coincide, the inner tank The space inside 401 and the space inside the tank body 4 (the space inside the tank body 4 refers to the space inside the tank body 4 located on the top of the first rotating plate 13) can be connected through the vent hole. When the first vent hole 14 and the second vent hole 19 are staggered, the space inside the inner tank 401 and the space inside the tank body 4 are separated by the first rotating plate 13 and the second rotating plate 20. It also includes a rotating rod 12 that is sequentially penetrated through the first rotating plate 13 and the second rotating plate 20 and a driving device 18 for controlling the rotation of the rotating rod 12. The rotating rod 12 is fixedly connected to the first rotating plate 13 and is rotatably connected to the second rotating plate 20. A fan blade 17 is provided at the bottom of the rotating rod 12, and a reciprocating mechanism is provided between the rotating rod 12 and the fan blade 17. When the rotating rod 12 rotates back and forth, the fan blade 17 always rotates in one direction. An intermittent mechanism is provided between the rotating rod 12 and the second rotating plate 20. When the rotating rod 12 rotates at a certain angle, the vent holes on the first rotating plate 13 and the second rotating plate 20 are staggered, and the second rotating plate 20 is driven to rotate.

[0024] Working principle: In the initial state, the first vent hole 14 and the second vent hole 19 are staggered, and in this embodiment, they are staggered by 45°. At this time, the space in the inner tank 401 is separated from the space in the tank body 4, and the liquid inlet 5 does not work. When working, the driving device 18 first drives the rotating rod 12 to rotate 90°, and drives the first rotating plate 13 to rotate 90°. During this period, the first vent hole 14 and the second vent hole 19 overlap once, and part of the smoke can pass from the inner tank 401 into the tank body 4. At this time, the intermittent mechanism is triggered, and then the liquid inlet 5 works to pass the absorption liquid into the tank body 4, and the rotating rod 12 continues to rotate 90°, the intermittent mechanism drives the second rotating plate 20 to rotate 90° together, during which the absorption liquid reacts with the smoke in the tank body 4 and falls on the first rotating plate 13, and moves to the surroundings under the centrifugal force, and falls into the space between the tank body 4 and the inner tank 401 through the leakage hole 15 on the leakage plate 16, and then stops passing the absorption liquid, and the driving device 18 drives the rotating rod 12 to reset, and drives the first rotating plate 13 and the second rotating plate 20 to reset to complete one work, and then repeats the above steps. During the whole working process, the fan blade 17 can always rotate in one direction through the reciprocating mechanism, and drive the smoke to move when rotating.

[0025] The present invention can cut the flue gas flow through the first rotating plate 13 and the second rotating plate 20, so that the flue gas flow is converted into a small flow, so that it can fully contact with the absorption liquid, improve the desulfurization and denitrification effect, and collect the absorbed liquid after the reaction separately, so that it is away from the unreacted flue gas and will not interact with the unreacted flue gas, thereby ensuring that the unreacted flue gas reacts with the unreacted absorption liquid and improves the reaction effect. In the present invention, only a driving device 18 is needed to drive the rotating rod 12 to rotate forward and reverse, and the structure is simple and the operation is convenient.

[0026] In addition, it should be noted that during the resetting period, the first vent hole 14 and the second vent hole 19 will also overlap once, and a part of the flue gas can pass from the inner tank 401 into the tank body 4. This part of the flue gas can react with the absorption liquid during the next operation, will not affect the work, and can improve the work efficiency to a certain extent.

[0027] In addition, it should be noted that, in actual use, the device can be set at a certain height with the cover 2 exposed. Even if a small amount of absorption liquid falls into the inner tank 401, the inner tank 401 can be cleaned, inspected and maintained through the flip cover at the bottom of the base 1.

[0028] As attached Figure 2 , Figure 3 , Figure 4As shown, the reciprocating mechanism in this embodiment includes a half gear A26 and a half gear B25 arranged on the rotating rod 12 along the up and down directions, and also includes a half gear plate 22 that can be vertically meshed with the half gear A26 and the half gear B25. The half gear plate 22 is connected to a full gear plate 23 via a connecting shaft. The full gear plate 23 is rotatably arranged in the inner tank 401 via a rotating shaft. The full gear plate 23 is vertically meshed with a full gear 24. The full gear 24 is rotatably arranged at the bottom of the rotating rod 12 and is connected to the fan blade 17.

[0029] Working principle: When the fan blade 17 rotates, it drives the full gear 24, the full toothed disc 23 and the half toothed disc 22 to rotate in turn. When the half toothed disc 22 rotates, it intermittently engages with the half gear A26 and the half gear B25, thereby controlling the forward and reverse rotation of the rotating rod 12, so that when the fan blade 17 works normally, it can drive the first rotating plate 13 and the second rotating plate 20 to work and reset.

[0030] As attached Figure 2 , Figure 3 , Figure 4 As shown, the intermittent mechanism in this embodiment includes a thread 27 arranged on the rotating rod 12 and a lifting tube 32 screwed on the rotating rod 12. Two top rods 29 are symmetrically arranged on the top of the lifting tube 32. A slot 28 adapted to the top rod 29 is arranged at the bottom of the second rotating plate 20. It also includes a first elastic limiting mechanism 30 for elastically limiting the lifting tube 32. When the rotating rod 12 rotates, the lifting tube 32 is driven to rise and fall. When the lifting tube 32 is lifted to the maximum position, it rotates with the rotating rod 12. It also includes a second elastic limiting mechanism 31 for elastically limiting the second rotating plate 20. In the natural state, the second rotating plate 20 remains stationary. When the top rod 29 is inserted into the slot 28 and rotates, it drives the second rotating plate 20 to rotate.

[0031] When the rotating rod 12 rotates, the lifting tube 32 is first raised and raised to the highest position by the first elastic limiting mechanism 30. At this time, the top rod 29 is inserted into the slot 28. As the rotating rod 12 continues to rotate, since the lifting tube 32 cannot continue to rise, the lifting tube 32 will overcome the first elastic limiting mechanism 30 and rotate with the rotating rod 12, thereby driving the second rotating plate 20 to overcome the second elastic limiting mechanism 31 and rotate, thereby realizing the first rotating plate 13 and the second rotating plate 20 to rotate in sequence. When resetting, the rotating rod 12 reverses, drives the lifting tube 32 to descend and descend to the lowest position, and then reverses to the initial position with the rotating rod 12 to realize the resetting of the lifting tube 32. In this embodiment, there are two symmetrical slots 28, which are not reversed during resetting, and are the same as the initial state, so as to realize the automatic resetting effect of the second rotating plate 20. That is, in this embodiment, the working process of the first rotating plate 13 in one operation and resetting is first to rotate 180° forward and then to reverse 180°, and the working process of the second rotating plate 20 is to rotate 180° forward.

[0032] As attached Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, in this embodiment, the first elastic limiting mechanism 30 includes a fixed outer sleeve 3001 and a roller 3002 arranged in the outer sleeve 3001, a first spring 3003 is provided between the roller 3002 and the outer sleeve 3001, and the lifting tube 32 is slidably arranged in the outer sleeve 3001 along the vertical direction through the roller 3002. When the rotating rod 12 rotates, the lifting tube 32 is driven to rise and fall. When the lifting tube 32 is lifted to the maximum position, it overcomes the elastic force of the first spring 3003 and rotates.

[0033] Working principle: The first spring 3003 and the roller 3002 generate pressure on the lifting tube 32, and the friction force of the lifting tube 32 during lifting is less than the friction force during rotation, so that when the lifting tube 32 is not lifted to the maximum position, the rotating rod 12 rotates, first driving the lifting tube 32 to do lifting movement. As attached Figure 2 , Figure 3 , Figure 5 , Figure 7 As shown, the second elastic limiting mechanism 31 in this embodiment includes a fixed disk body 3101. The setting of the disk body 3101 can be achieved by fixedly connecting it to the inner tank 401. The disk body 3101 is located below the second rotating plate 20. A second spring 3102 is provided on the top of the disk body 3101, and a universal ball 3103 is connected through the second spring 3102. In the natural state, the second rotating plate 20 remains stationary. When the top rod 29 is inserted into the slot 28 and rotates, it drives the second rotating plate 20 to rotate by overcoming the elastic force of the second spring 3102.

[0034] Working principle: pressure is generated on the second rotating plate 20 through the second spring 3102 and the universal ball 3103. When the second rotating plate 20 is not subjected to external force, it can remain stationary. In addition, in this embodiment, the slot 28 is a conical slot, and the top of the conical slot is adapted to the push rod 29. Even when the second rotating plate 20 rotates slightly and there is a slight error in the position of the slot 28 and the push rod 29, the push rod 29 can still be smoothly inserted into the slot 28 and the position of the second rotating plate 20 can be adjusted.

[0035] As attached Figure 2 , Figure 3 , Figure 8 As shown, the driving device 18 in this embodiment is a motor fixedly arranged under the fan blade 17, the liquid inlet 5 is connected to a pipeline, a connecting pipe 7 is provided between the pipeline and the rotating rod 12, the connecting pipe 7 is rotatably connected to the pipeline and fixedly connected to the rotating rod 12, the connecting pipe 7 is connected to a branch 8, the branch 8 is connected to a support pipe 9, a sprinkler head 10 is connected via the support pipe 9, and the support pipe 9 is fixedly connected to the rotating rod 12.

[0036] Working principle: When working, the spray head 10 will rotate with the rotating rod 12, so that the absorption liquid can be sprayed more evenly, and the absorption liquid and the flue gas can be stirred to a certain extent by setting the stirring rod 11, thereby improving the reaction effect.
