Description

Technical Field

[0001] The invention relates to the field of industrial waste gas filtering, and in particular to an industrial waste gas filtering and purification device. Background Art

[0002] In the process of industrial waste gas filtration, there are the following problems;

[0003] 1. When filtering industrial waste gas, it is necessary to remove particles and combustibles in the industrial waste gas for subsequent treatment of the industrial waste gas. However, when removing particles in the industrial waste gas, the particles will adhere to the filter equipment, causing the filter equipment to lose its filtering effect. It is necessary to stop the machine to clean or replace the filter equipment. However, due to the high cost of replacing the filter equipment, the filter equipment is usually cleaned and then reused, which is troublesome to clean;

[0004] 2. When treating industrial waste gas with lime slurry, the lime slurry cannot fully react with the industrial waste gas due to its fast flow speed. Moreover, when the lime slurry is sprayed into the industrial waste gas, the lime slurry can only react with the industrial waste gas that is in contact with its surface. The industrial waste gas that has not been in contact with the lime slurry is not treated, resulting in the treatment of the industrial waste gas being affected and failing to meet the emission standards. Summary of the invention

[0005] In order to overcome the disadvantages of having to shut down the machine to clean the filter equipment, which is troublesome to clean and the industrial waste gas cannot fully react, the present invention provides an industrial waste gas filtering and purification device.

[0007] As a further preferred solution, the first filter plate is designed to be arc-shaped.

[0008] As a further preferred scheme, the flue gas treatment component includes a first injection pipe, a third guide plate and a second injection pipe; the first injection pipe is fixedly connected to the right side of the box body, and the injection port of the first injection pipe is facing the box body; the third guide plate is fixedly connected to the right side of the box body, and the third guide plate is located above the first injection pipe; the second injection pipe is fixedly connected to the third guide plate, and the injection port on the second injection pipe is staggered with the injection port on the first injection pipe.

[0009] As a further preferred solution, a reflux point is provided on the third guide plate.

[0010] As a further preferred solution, there is also an arc plate; the arc plate is connected to the box body, and the arc plate is in contact with the second guide plate.

[0011] As a further preferred solution, the box body and the arc-shaped plate are movably connected.

[0012] As a further preferred solution, a third injection pipeline is also included; the third injection pipeline is fixedly connected to the inside of the box body, and the third injection pipeline is located on the left side of the arc plate.

[0013] As a further preferred solution, the left side of the third injection pipeline is connected to the water curtain injection pipe.

[0014] As a further preferred scheme, it also includes a rotating dial plate, a fifth filter plate and a sixth filter plate; a sealing plate is provided on the left side of the box; a transfer channel is formed between the first guide plate and the second fixed block; a rotating dial plate is rotatably connected to the box, and the rotating dial plate is in contact with the first guide plate; the first fixed block and the first guide plate are jointly fixed with the fifth filter plate; and the sixth filter plate is fixed inside the box.

[0015] As a further preferred solution, an inclined portion is provided on the second guide plate.

[0016] The beneficial effect is that the present invention filters the industrial waste gas multiple times through the first filter plate, the second filter plate and the fourth filter plate, ensuring that all particles in the industrial waste gas can be intercepted.

[0017] The present invention pushes the third filter plate through the first filter plate, and the torsion spring at the connection between the box and the third filter plate begins to be stressed, pushing the third filter plate upward. In the process of the third filter plate flipping upward, the flamethrower is pulled to flip left by a thin rope, so that the flamethrower sprays flames toward the first filter plate, the second filter plate and the third filter plate to flush. The flames sprayed from the two flamethrowers form a larger flame, which flushes the oil and particles solidified on the first filter plate, the second filter plate and the third filter plate through high temperature and transfers them to the bottom of the third filter plate. After the interchange is completed, the industrial waste gas is guided to the second filter plate for filtering treatment through the guidance of the arc design, so as to avoid affecting the normal filtration of the industrial waste gas.

[0018] The present invention makes the lime slurry sprayed out of the first injection pipe and the second injection pipe form an interlaced state. After the industrial waste gas moves to the injection area of ​​the first injection pipe, the industrial waste gas reacts with the lime slurry sprayed by the first injection pipe to form sulfides that fall downward onto the first guide plate. While the industrial waste gas reacts with the lime slurry, the industrial waste gas is divided into multiple parts by the lime slurry discharged from the first injection pipe, and the industrial waste gas divided into multiple parts is transferred upward. When the industrial waste gas divided into multiple parts moves to the injection area of ​​the second injection pipe, the industrial waste gas is divided into multiple parts, so that the industrial waste gas can react with the lime slurry better, thereby avoiding the industrial waste gas being unable to fully react with the lime slurry, which affects the treatment of the industrial waste gas.

[0019] The present invention guides the industrial waste gas at the reflux point so that the industrial waste gas passing through the injection area of ​​the second injection pipe returns to the injection area of ​​the second injection pipe for reaction again, thereby ensuring that the industrial waste gas can react effectively.

[0020] The present invention sprays lime slurry from the first injection pipe and the second injection pipe onto the arc plate, and the lime slurry forms splashes on the arc plate, so that the lime slurry is better diffused in the working area of ​​the flue gas treatment component. The box body and the arc plate are movably connected. When the lime slurry flushes the arc plate, the arc plate rotates randomly, so that the diffusion effect of the lime slurry is further improved, and the industrial waste gas and the lime slurry react more fully.

[0021] The invention transfers oil dirt and particles downwards by the downwardly flowing lime slurry, transfers them to the bottom of the box body for mixing, and forms a mass at the bottom of the box body, which is convenient for subsequent cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example 1

[0029] An industrial waste gas filtering and purification device, such as Figure 1-3 As shown, it includes a box body 1, an air intake duct 2, a first fixing block 3, a first guide plate 4, a second fixing block 5 and a second guide plate 6; an opening is provided at the top of the box body 1; the air intake duct 2 is connected to the left side of the box body 1; the first fixing block 3 and the first guide plate 4 are fixedly connected in the box body 1, and the first fixing block 3 is located on the left side of the first guide plate 4; the second fixing block 5 and the second guide plate 6 are fixedly connected in the box body 1, the second guide plate 6 is located above the first guide plate 4, and the second fixing block 5 is located between the first guide plate 4 and the second guide plate 6;

[0030] It also includes a flame-spraying tube 7, a first filter plate 8, a second filter plate 9, a third filter plate 10, a fourth filter plate 11, a delivery pipeline 12 and a flue gas treatment component; a flame-spraying tube 7 is rotatably connected to the upper surface of the second fixed block 5 and the lower surface of the second guide plate 6; a motor is provided at the front side of the box body 1; a first filter plate 8 is rotatably connected in the box body 1, and the rotating shaft of the first filter plate 8 is fixedly connected to the output shaft of the motor at the front side of the box body 1, and the first filter plate 8 is located between the first fixed block 3 and the second guide plate 6; the first fixed block 3 and the second fixed block 5 are jointly fixed with the second filter plate 9, and the second filter plate 9 is in an inclined state of the lower left and upper right; the second guide plate 6 is hinged with the third filter plate 10 through a torsion spring, and the left end of the third filter plate 10 is connected to all the flame-spraying tubes 7 through a metal rope; the second fixed block 5 and the second guide plate 6 are jointly fixed with the fourth filter plate 11, and the fourth filter plate 11 is located on the right side of the flame-spraying tube 7; a delivery pipeline 12 is connected to the right side of the box body 1; a flue gas treatment component is installed in the box body 1, and the delivery pipeline 12 is connected to the flue gas treatment component.

[0031] The first filter plate 8 is designed to be arc-shaped, and through the arc-shaped design of the first filter plate 8, the first filter plate 8 can intercept more particles and achieve a better filtering effect.

[0032] In the present invention, an anti-flashback device is provided in the air intake pipe 2 to prevent the flashback phenomenon of the industrial waste gas.

[0033] Before filtering the industrial waste gas, the air intake pipe 2 is connected to the external waste gas conveyor, the flamethrower pipe 7 is connected to the external flamethrower, the conveying pipe 12 is connected to the liquid transferor, the flue gas treatment component is connected to the external lime slurry conveyor, the external waste gas conveyor is started to transport the industrial waste gas to be treated through the air intake pipe 2 to the box body 1, and the filtering operation of the industrial waste gas is started. The flamethrower is started, and the flamethrower pipe 7 on the second fixed block 5 and the second guide plate 6 starts to spray flames. After the industrial waste gas is transferred to the box body 1, it impacts the first filter plate 8. After the industrial waste gas impacts the first filter plate 8, the first filter plate 8 intercepts the particles in the industrial waste gas. Through the arc design of the first filter plate 8, the first filter plate 8 can intercept more particles to achieve a better filtering effect. The industrial waste gas generally carries oil stains. At this time, the particles intercepted by the first filter plate 8 are adhered to the first filter plate 8 through the oil stains. Considering the filtration efficiency of the first filter plate 8 alone , it is impossible to filter all the industrial waste gas transported, and some of the industrial waste gas will be transferred upward or downward under the guidance of the arc-shaped design of the first filter plate 8. The industrial waste gas transferred upward will continue to transfer to the right after contacting the second guide plate 6, and the industrial waste gas transferred downward will continue to transfer to the right after contacting the first fixed block 3, and then the filtration of this part of the industrial waste gas will be completed through the third filter plate 10, and the industrial waste gas will continue to transfer to the right. When the industrial waste gas is transferred to the area where the flame is sprayed by the flame-spraying pipe 7, the flame is sprayed by the flame-spraying pipe 7 to burn the combustibles in the industrial waste gas, so that the combustibles in the industrial waste gas are reduced, which is convenient for subsequent processing. Considering that the first filter plate 8 and the second filter plate 9 cannot intercept all the particles in the industrial waste gas, after the industrial waste gas moves to the right out of the area where the flame is sprayed by the flame-spraying pipe 7, the industrial waste gas continues to move to the right, and the industrial waste gas is filtered again by the fourth filter plate 11 to ensure that all the particles in the industrial waste gas can be intercepted.

[0034] After being used for a certain period of time, the left side of the first filter plate 8 is occupied by oil and particles and loses its interception ability, affecting the filtration of industrial waste gas. At this time, the motor on the front side of the box body 1 is started to drive the first filter plate 8 to rotate counterclockwise 180 degrees from the front to the back, and the right side and the left side of the first filter plate 8 that still have the interception ability are interchanged. During the interchange process, the first filter plate 8 pushes the third filter plate 10, and the torsion spring at the connection between the box body 1 and the third filter plate 10 begins to be stressed, pushing the third filter plate 10 upward. In the process of the third filter plate 10 flipping upward, the flamethrower 7 is pulled to the left by a thin rope, so that the flamethrower 7 sprays flames toward the first filter plate 8, the second filter plate 9 and the third filter plate 10 to flush, and the flames sprayed from the two flamethrower 7 form a ball A larger flame will flush out the oil and particles trapped on the first filter plate 8, the second filter plate 9 and the third filter plate 10 through high temperature, and transfer them to the bottom of the third filter plate 10. After the interchange is completed, the industrial waste gas is guided to the second filter plate 9 for filtering through the arc-shaped guide design to avoid affecting the normal filtration of the industrial waste gas. After the first filter plate 8, the second filter plate 9 and the third filter plate 10 are cleaned, the first filter plate 8 is reset by the motor on the front side of the box body 1, and the corresponding parts follow the changes. The oil and particles solidified on the fourth filter plate 11 can be flushed down when the two flamethrower tubes 7 are facing each other, and drip onto the first guide plate 4 to avoid affecting the filtration of the industrial waste gas.

[0035] Afterwards, the industrial waste gas passes through the fourth filter plate 11 and is transferred to the working area of ​​the flue gas treatment component, and the industrial waste gas is subsequently treated by the flue gas treatment component.

[0036] Example 2

[0037] On the basis of Example 1, Figure 2-4 As shown, the flue gas treatment component includes a first injection pipe 101, a third guide plate 102 and a second injection pipe 103; the first injection pipe 101 is fixedly connected to the upper right side of the box body 1, and the injection port of the first injection pipe 101 faces into the box body 1; the third guide plate 102 is fixedly connected to the upper right side of the box body 1, and the third guide plate 102 is located above the first injection pipe 101; the second injection pipe 103 is fixedly connected to the third guide plate 102, and the injection port on the second injection pipe 103 is staggered with the injection port on the first injection pipe 101.

[0038] A reflux point 102a is provided on the third guide plate 102. The reflux point 102a guides the industrial waste gas so that the industrial waste gas passing through the injection area of ​​the second injection pipe 103 returns to the injection area of ​​the second injection pipe 103 for reaction again, thereby ensuring that the industrial waste gas can react effectively.

[0039] The box body 1 further includes an arc plate 104 ; the arc plate 104 is connected to the box body 1 , and the arc plate 104 is in contact with the second guide plate 6 .

[0040] The box body 1 and the arc plate 104 are movably connected. When the lime slurry flushes the arc plate 104, the arc plate 104 rotates freely, so that the diffusion effect of the lime slurry is further improved, and the industrial waste gas and the lime slurry react more fully.

[0041] It also includes a third injection pipeline 105 ; the third injection pipeline 105 is fixedly connected to the top surface of the box body 1 , and the third injection pipeline 105 is located on the left side of the arc plate 104 .

[0042] The left side of the third injection pipeline 105 is connected to the water curtain injection pipe 105a, and a lime slurry water curtain is formed on the left side of the injection area of ​​the third injection pipeline 105 through the water curtain injection pipe 105a, ensuring that no unreacted industrial waste gas will be transferred outward.

[0043] In the present invention, the injection ports of the first injection pipeline 101, the second injection pipeline 103 and the third injection pipeline 105 are all atomizing nozzles.

[0044] When the industrial waste gas moves to the working area of ​​the flue gas treatment component, the external lime slurry conveyor is started to transport the lime slurry to the first injection pipe 101, the second injection pipe 103 and the third injection pipe 105 for spraying, and the industrial waste gas begins to be treated. At this time, the lime slurries sprayed from the first injection pipe 101 and the second injection pipe 103 are staggered. After the industrial waste gas moves to the injection area of ​​the first injection pipe 101, the industrial waste gas reacts with the lime slurry sprayed from the first injection pipe 101 to form sulfides that fall downward onto the first guide plate 4. At the same time, the industrial waste gas is divided into multiple portions by the lime slurry discharged from the first injection pipe 101, and the industrial waste gas divided into multiple portions is transferred upward. It should be noted that when a certain amount of lime slurry accumulates at the bottom of the box body 1, the lime slurry will block the conveying pipe 12, and the industrial waste gas cannot be transferred from the conveying pipe 12. When the industrial waste gas divided into multiple portions moves to the injection area of ​​the second injection pipe 103, the industrial waste gas is divided into multiple portions, so that the industrial waste gas can better react with the lime slurry, thereby avoiding the industrial waste gas being unable to fully react with the lime slurry, which affects the treatment of the industrial waste gas.

[0045] Taking into account the high speed of industrial waste gas flow, the industrial waste gas may be transferred out of the reaction area before the reaction is completed, which affects the treatment of the industrial waste gas. After the industrial waste gas passes through the injection area of ​​the second injection pipe 103, the industrial waste gas is transferred to the reflux point 102a. The reflux point 102a guides the industrial waste gas so that the industrial waste gas that passes through the injection area of ​​the second injection pipe 103 returns to the injection area of ​​the second injection pipe 103 to react again, ensuring that the industrial waste gas can react effectively. The airflow formed by the lime slurry sprayed from the first injection pipe 101 and the second injection pipe 103 guides the industrial waste gas to the left, so that the industrial waste gas that has completed the reaction is transferred to the left. At the same time, the lime slurry sprayed from the first injection pipe 101 and the second injection pipe 103 is sprayed on the curved plate 104. The lime slurry is sprayed on the curved plate 104. 04 to form sputtering, so that the lime slurry can be better diffused in the working area of ​​the flue gas treatment component. The box body 1 is movably connected with the arc plate 104. When the lime slurry flushes the arc plate 104, the arc plate 104 rotates freely, so that the diffusion effect of the lime slurry is further enhanced, and the industrial waste gas and the lime slurry react more fully. In order to ensure that the industrial waste gas that has reacted with the lime slurry can be discharged directly, the lime slurry sprayed out from the third injection pipe 105 is in contact with the industrial waste gas again to determine whether the industrial waste gas has reacted sufficiently, so as to avoid the unreacted industrial waste gas from transferring outward. While the third injection pipe 105 is spraying lime slurry, a lime slurry water curtain is formed on the left side of the injection area of ​​the third injection pipe 105 through the water curtain injection pipe 105a to ensure that no unreacted industrial waste gas will be transferred outward.

[0046] Example 3

[0047] On the basis of Example 2, Figure 2-3 As shown, it also includes a rotating dial plate 201, a fifth filter plate 202 and a sixth filter plate 203; a sealing plate 1a is provided on the left side of the box body 1; a transfer channel 5a is formed between the first guide plate 4 and the second fixed block 5; a rotating dial plate 201 is rotatably connected in the box body 1, and the rotating dial plate 201 is in contact with the first guide plate 4; the first fixed block 3 and the first guide plate 4 are jointly fixedly connected to the fifth filter plate 202; and the sixth filter plate 203 is fixedly connected to the left side of the box body 1.

[0048] The second guide plate 6 is provided with an inclined portion 6a, through which the lime slurry of the lime slurry water curtain sprayed from the water curtain spraying pipe 105a is guided, and the lime slurry is transferred to between the second guide plate 6 and the arc plate 104 to fall downward, thereby enhancing the transfer of the accumulated sulfides.

[0049] When the flue gas treatment component treats the industrial waste gas, the formed sulfide accumulates on the first guide plate 4, affecting the transfer of the industrial waste gas. At this time, the first injection pipe 101 and the second injection pipe 103 spray lime slurry on the curved plate 104, forming a lime slurry water flow falling downward, carrying the accumulated sulfide to the transfer channel 5a. Considering that the lime slurry water flow formed on the curved plate 104 cannot transfer the accumulated sulfide to the transfer channel 5a well, at this time, the lime sprayed from the water curtain injection pipe 105a is sprayed through the inclined portion 6a. The lime slurry of the slurry water curtain is guided, and the lime slurry is transferred to the space between the second guide plate 6 and the arc plate 104 and falls downward, so as to strengthen the transfer of the accumulated sulfide and avoid affecting the transfer of the industrial waste gas. When the lime slurry falls downward, it contacts with the unreacted industrial waste gas and reacts with it to reduce the concentration of the industrial waste gas, so as to facilitate the subsequent reaction with the lime slurry. After the sulfide is transferred to the transfer channel 5a, it continues to move to the left. At this time, the water flow formed by the lime slurry pushes the rotating dial plate 201, so that the rotating dial plate 201 moves from the front to the back. Looking back, rotating counterclockwise, when the sulfide contacts the rotating dial plate 201, the rotating dial plate 201 moves the lime slurry and sulfide to the left, so that the lime slurry and sulfide are better distributed on the fifth filter plate 202. At this time, the oil stains and particles on the first filter plate 8, the second filter plate 9 and the third filter plate 10 are not cleaned, and the fifth filter plate 202 is attached with lime slurry. When the oil stains and particles on the first filter plate 8, the second filter plate 9 and the third filter plate 10 are cleaned, the oil stains and particles fall downward onto the fifth filter plate 202. The downwardly flowing lime slurry carries oil and particles downward and is transferred to the bottom of the box 1 for mixing, forming a clumping mass at the bottom of the box 1 to facilitate subsequent cleaning. At the same time, the lime slurry at the bottom of the box 1 is extracted through the conveying pipe 12 and transported for reuse through an external lime slurry conveyor to reduce the loss of lime slurry. Considering that there are still clumping objects at the bottom of the box 1 that will affect it, the clumping objects are intercepted by the sixth filter plate 203 at this time to avoid affecting the reuse of the lime slurry at the bottom of the box 1.

[0050] After the industrial waste gas is filtered, the sealing plate 1a is opened manually to clean the lumpy objects at the bottom of the box body 1.
