Description

Technical Field

[0001] The present invention relates to the technical field of flue gas desulfurization for processing rock wool waste, and specifically to a flue gas desulfurization device for processing rock wool waste. Background Art

[0002] Desulfurization generally refers to the process of removing sulfur from fuels before combustion and removing sulfur from flue gas before emission. It is one of the important technical measures for preventing and controlling air pollution. Desulfurization technologies at home and abroad are classified into three major processes: wet desulfurization, semi-dry desulfurization, and dry desulfurization according to whether water is added during the desulfurization process and the dry-wet form of the desulfurization products. Currently, 80% of the processes of large domestic desulfurization units are wet desulfurization technologies, among which the most widely used is the limestone-gypsum method desulfurization. The main process flow is to use limestone or lime as the desulfurization absorbent. The limestone is crushed and ground into powder, mixed with water and stirred into an absorption slurry. Then, the absorption slurry in the absorption tower contacts and mixes with the flue gas. Sulfur dioxide in the flue gas reacts chemically with calcium carbonate in the slurry and the introduced oxidation air to be removed. The desulfurized flue gas is removed of the fine droplets carried out by a demister, heated and raised in temperature by a heater, and then discharged into the chimney. A desulfurization device is also used during the processing of rock wool waste.

[0003] However, research shows that the existing flue gas desulfurization device for processing rock wool waste still has the following defects:

[0004] The existing flue gas desulfurization device for processing rock wool waste generally sends sulfur-containing gas into the device through an inlet pipe. When the sulfur-containing gas comes out of the inlet pipe, it will rise and react with the desulfurizing agent. This will cause the sulfur-containing gas not to disperse, unable to fully react with the desulfurizing agent, resulting in incomplete desulfurization of the sulfur-containing gas. At the same time, the fixed particles formed by the reaction may accumulate at the bottom of the device, which is difficult to clean and may block the drain pipe. Therefore, it is necessary to optimize a flue gas desulfurization device for processing rock wool waste through technological innovation and design optimization. Summary of the Invention

[0005] Existing flue gas desulfurization devices for processing rock wool waste generally send sulfur-containing gases into the device through an inlet pipe. When the sulfur-containing gas comes out of the inlet pipe, it will rise and react with the desulfurizing agent. This will cause the sulfur-containing gas to be non-dispersed and unable to fully react with the desulfurizing agent, resulting in incomplete desulfurization of the sulfur-containing gas. At the same time, the fixed particles formed by the reaction may accumulate at the bottom of the device, making it difficult to clean and may block the drain pipe. To solve the above problems, the embodiment of the present application provides a flue gas desulfurization device for processing rock wool waste. By setting a fixed frame and a fixed plate, it is convenient to guide and disperse the sulfur-containing gas, avoiding the sulfur-containing gas from all rising near the inlet pipe position, enabling the sulfur-containing gas to disperse and rise, facilitating the full contact of the sulfur-containing gas with the desulfurizing agent sprayed by the nozzle. At the same time, the cleaning mechanism can clean the fixed plate to prevent solid particles from blocking the round holes. The motor two drives the screw rod to rotate, which can discharge the solid particles deposited inside the protective shell and the drain pipe, avoiding the blockage of the drain pipe by solid particles.

[0006] The technical solution adopted by the embodiment of the present application to solve its technical problems is:

[0007] A flue gas desulfurization device for processing rock wool waste, comprising:

[0008] A housing;

[0009] Among them, a first inlet pipe and a second inlet pipe are installed on the housing. Nozzles are installed on both the first inlet pipe and the second inlet pipe. A demister is fixed at the top of the second inlet pipe inside the housing. A fixed plate is fixed inside the housing. Round holes are opened on the fixed plate. A cleaning mechanism for cleaning the fixed plate is provided at the top of the fixed plate.

[0010] In a possible implementation manner, the housing includes a protective shell. An exhaust pipe is installed at the top of the protective shell. An inlet pipe is installed on one side of the protective shell. A drain pipe is installed on the other side of the housing.

[0012] Among them, the rotating mechanism includes a screw rod provided inside the drain pipe. One end of the screw rod is rotatably connected to the protective shell. A motor two is installed on the drain pipe. The output end of the motor two penetrates the drain pipe and is fixedly connected to the screw rod. A drain port is opened at the bottom of the drain pipe. The motor two drives the screw rod to rotate. The screw rod will rotate inside the protective shell and the drain pipe, discharging the solid particles deposited inside the protective shell and the drain pipe, avoiding the blockage of the drain pipe by solid particles.

[0013] In a possible implementation manner, a fixed frame is fixed at the bottom of the fixed plate. A plurality of partitions are linearly arranged and fixed inside the fixed frame, facilitating the collection and guidance of sulfur-containing gases.

A guiding column is fixed to the top of the brush plate, and the top of the guiding column penetrates through the moving plate. A fixing block is fixed to the top of the moving plate, and a lead screw passes through the fixing block. One end of the lead screw is rotatably connected to the protective shell, and a first motor is installed on the outer side of the protective shell. The first motor penetrates through the protective shell and is fixedly connected to the lead screw. The first motor drives the lead screw to rotate. The lead screw drives the moving plate to move through the fixing block. The moving plate drives the brush plate to move through the guiding column, and the brush plate cleans the fixed plate to prevent solid particles from blocking the round holes.

[0015] In a possible implementation, a spring is sleeved between the brush plate and the moving plate on the outer portion of the guiding column. A baffle is fixed to the top of the guiding column, and the spring is in a compressed state. The spring always applies a pressure to the brush plate, so that the brush plate and the fixed plate are more closely attached, which is convenient for improving the cleaning efficiency of the brush plate.

[0016] In a possible implementation, sliding grooves are formed on both sides inside the protective shell, and sliding blocks are arranged inside the sliding grooves. The sliding blocks are fixedly connected to the moving plate, and the moving plate drives the sliding blocks to slide in the sliding grooves, which is convenient for improving the stability of the moving plate during movement.

[0017] In a possible implementation, the bottom of the fixed frame is provided with an inclined surface, and the lengths of several partition plates increase in sequence from the position close to the air inlet pipe to the position far from the air inlet pipe, which is convenient for guiding and evacuating the sulfur-containing gas, preventing the sulfur-containing gas from all rising from the position close to the air inlet pipe, enabling the sulfur-containing gas to disperse and rise, and facilitating the full contact between the sulfur-containing gas and the desulfurizing agent sprayed by the spray head.

[0018] In a possible implementation, a bottom plate is provided at the bottom inside the protective shell, and a groove is formed on the bottom plate. The groove can accommodate the rotation of the spiral rod. The top of the bottom plate is provided with an inclined surface, which is convenient for solid particles to gather inside the groove.

[0019] In a possible implementation, the first water inlet pipe and the second water inlet pipe are arranged in a crosswise and perpendicular manner, which is convenient for reducing the spraying dead angle.

[0020] In summary, the present invention includes at least one of the following beneficial technical effects:

[0021] 1. The motor 1 drives the lead screw to rotate. The lead screw drives the moving plate to move through the fixed block. The moving plate drives the brush plate to move through the guide post.

[0022] 2. The motor 2 drives the spiral rod to rotate. The spiral rod rotates inside the protective shell and inside the drain pipe, discharging the solid particles deposited inside the protective shell and the drain pipe, preventing the solid particles from blocking the drain pipe.

[0023] 3. The bottom of the fixed frame is set as an inclined plane, and the lengths of several partition plates increase successively from the position close to the air inlet pipe to the position far from the air inlet pipe, facilitating the guiding and dispersion of the sulfur-containing gas, preventing the sulfur-containing gas from rising entirely from the position close to the air inlet pipe, enabling the sulfur-containing gas to rise dispersedly, and facilitating the full contact between the sulfur-containing gas and the desulfurizing agent sprayed by the spray head.

[0031] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples, and the instrument placement rack related to the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0032] This embodiment introduces the specific structure of a flue gas desulfurization device for processing rock wool waste. Specifically, refer to Figures 1 - 6 As shown, a flue gas desulfurization device for processing rock wool waste includes:

[0033] A housing;

[0034] Among them, a first water inlet pipe 2 and a second water inlet pipe 5 are installed on the housing. Spray heads 10 are installed on both the first water inlet pipe 2 and the second water inlet pipe 5. Inside the housing, a demister 11 is fixed at the top of the second water inlet pipe 5. A fixing plate 23 is fixed inside the housing. A circular hole 24 is opened on the fixing plate 23. A cleaning mechanism for cleaning the fixing plate 23 is provided at the top of the fixing plate 23.

[0035] In addition, the housing includes a protective shell 3. An exhaust pipe 4 is installed at the top of the protective shell 3. An intake pipe 1 is installed on one side of the protective shell 3. A drain pipe 7 is installed on the other side of the protective shell 3.

[0036] Fixed particles will accumulate at the bottom inside the protective shell 3. A rotating mechanism is installed inside the drain pipe 7;

[0037] Among them, the rotating mechanism includes a screw rod 9 provided inside the drain pipe 7. One end of the screw rod 9 is rotatably connected to the protective shell 3. A second motor 8 is installed on the drain pipe 7. The output end of the second motor 8 penetrates the drain pipe 7 and is fixedly connected to the screw rod 9. A drain port is opened at the bottom of the drain pipe 7. The second motor 8 drives the screw rod 9 to rotate. The screw rod 9 will rotate inside the protective shell 3 and the drain pipe 7 to discharge the solid particles precipitated inside the protective shell 3 and the drain pipe 7, avoiding blockage of the drain pipe 7 by solid particles.

[0038] When the sulfur-containing gas enters the inside of the protective shell 3 from the intake pipe 1, a fixing frame 12 is fixed at the bottom of the fixing plate 23. A number of partition plates 25 are linearly arranged and fixed inside the fixing frame 12, which is convenient for collecting and guiding the sulfur-containing gas.

[0039] When the fixed particles fall onto the fixed plate 23, the cleaning mechanism includes a moving plate 15 arranged on the top of the top plate. A brush plate 14 is arranged between the moving plate 15 and the fixed plate 23. A guide post 19 is fixed to the top of the brush plate 14. The top of the guide post 19 penetrates through the moving plate 15. A fixed block is fixed to the top of the moving plate 15. A lead screw 16 penetrates through the fixed block. One end of the lead screw 16 is rotatably connected to the protective shell 3. A first motor 6 is installed on the outer side of the protective shell 3. The first motor 6 penetrates through the protective shell 3 and is fixed to the lead screw 16. The first motor 6 drives the lead screw 16 to rotate. The lead screw 16 drives the moving plate 15 to move through the fixed block. The moving plate 15 drives the brush plate 14 to move through the guide post 19. The brush plate 14 cleans the fixed plate 23 to prevent the solid particles from blocking the round holes 24.

[0040] When the brush plate 14 moves, a spring 18 is sleeved between the brush plate 14 and the moving plate 15 on the outside of the guide post 19. A baffle 21 is fixed to the top of the guide post 19. The spring 18 is in a compressed state. The spring 18 always gives a pressure to the brush plate 14, so that the brush plate 14 and the fixed plate 23 are more closely attached, which is convenient for improving the cleaning efficiency of the brush plate 14.

[0041] When the moving plate 15 moves, sliding grooves 22 are opened on both sides inside the protective shell 3. Sliding blocks 20 are arranged inside the sliding grooves 22. The sliding blocks 20 are fixedly connected to the moving plate 15. The moving plate 15 drives the sliding blocks 20 to slide in the sliding grooves 22, which is convenient for improving the stability of the moving plate 15 when it moves.

[0042] It should be noted that the bottom of the fixed frame 12 is arranged in an inclined plane. The lengths of several partition plates 25 increase in sequence from the position close to the air inlet pipe 1 to the position far from the air inlet pipe 1, which is convenient for guiding and evacuating the sulfur-containing gas, preventing the sulfur-containing gas from all rising from the position close to the air inlet pipe 1, so that the sulfur-containing gas can rise dispersedly, which is convenient for the sulfur-containing gas to fully contact with the desulfurizing agent sprayed by the spray head 10.

[0043] When the solid particles sink to the bottom of the protective shell 3, a bottom plate 13 is arranged at the bottom inside the protective shell 3. A groove 17 is opened on the bottom plate 13. The groove 17 can accommodate the rotation of the spiral rod 9. The top of the bottom plate 13 is arranged in an inclined plane, which is convenient for the solid particles to gather inside the groove 17. The spiral rod 9 can rotate and discharge the solid particles in the groove 17, which is convenient for the fixed particles to accumulate at the bottom of the protective shell 3.

[0044] Moreover, the first water inlet pipe 2 and the second water inlet pipe 5 are arranged in a crosswise and perpendicular manner, which is convenient for reducing the spraying dead angle.

[0045] The sulfur-containing gas enters the interior of the protective shell 3 from the intake pipe 1. After being guided by the fixing frame 12 and dispersed by the wind of the fixing plate 23, the sulfur-containing gas continues to move upward and contacts the desulfurizing agent sprayed by the spray head 10 for reaction. After the reaction, solid particles are generated. The desulfurized gas is discharged from the exhaust pipe 4 through the demister 11. Part of the fixed particles and the desulfurizing agent pass through the round holes 24 on the fixing plate 23, and part of them fall on the fixing plate 23. The first motor 6 is started, and the first motor 6 drives the lead screw 16 to rotate. The lead screw 16 drives the moving plate 15 to move through the fixing block. The moving plate 15 drives the brush plate 14 to move through the guide post 19. The brush plate 14 cleans the fixing plate 23. The spring 18 is in a compressed state, and the spring 18 always gives a pressure to the brush plate 14, so that the brush plate 14 and the fixing plate 23 are more closely attached, which is convenient to improve the cleaning efficiency of the brush plate 14 and prevent the solid particles from blocking the round holes 24. The fallen desulfurizing agent and solid particles fall into the groove 17. The second motor 8 drives the screw rod 9 to rotate. The screw rod 9 rotates inside the protective shell 3 and the drain pipe 7, and discharges the solid particles deposited inside the protective shell 3 and the drain pipe 7, preventing the solid particles from blocking the drain pipe 7.

[0046] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. The obvious changes or variations derived therefrom still fall within the protection scope of the present invention.
