Description

Technical Field

[0001] This invention belongs to the field of desulfurization technology, specifically a high-efficiency desulfurization tower. Background Technology

[0002] Towers are mostly used for desulfurization and ash removal of industrial waste gas. Most towers are tower-shaped, with granite-built towers being widely used in industrial desulfurization. Because towers mostly use the water film desulfurization and dust removal principle, they are also known as granite water film desulfurization and dust removal devices. The advantages of towers are that they are easy to maintain, and by preparing different dust removal agents, the towers can achieve the effects of dust removal and desulfurization at the same time.

[0003] Most existing towers use spray desulfurization. However, due to the relatively large diameter of the spray droplets and the high spray density, the sprayed liquid often fails to fully react with the SO2 in the gas. Furthermore, it can easily result in the gas being discharged without being properly cleaned of dust. This leads to low tower efficiency and the exhaust gas failing to meet emission standards.

[0004] In view of this, in order to overcome the above-mentioned technical problems, this invention designs and develops a high-efficiency desulfurization tower, which solves the above-mentioned technical problems. Summary of the Invention

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] This invention provides a high-efficiency desulfurization tower, comprising a tower body 1,

[0042] Air inlet 2, which is located on the left side of the tower body 1;

[0043] Drainage port 3 is located on the right side of tower body 1;

[0044] Air outlet 4, which is located above the tower body 1;

[0045] Storage tank 5 is located inside tower body 1 and is connected to drain port 3;

[0046] The desulfurization tower also includes a cleaning component, which is disposed inside the tower body 1 and is used to clean SO2 and dust contained in the gas inside the tower body 1.

[0047] A power assembly is disposed inside the tower body 1 and above the cleaning assembly. The power assembly is used to provide power to the cleaning assembly when the cleaning assembly is working.

[0048] This invention improves the reaction efficiency of SO2 in the liquid and gas sprayed by the spraying equipment by purifying the gas inside the tower body 1 through the cleaning component and the power component that provides power to the cleaning component. This invention improves the working efficiency of the tower body by improving the internal structure of the tower body, thereby ensuring that the emissions of the tower body can meet the emission standards.

[0049] In one specific embodiment of the present invention, the cleaning component includes:

[0050] The sprayer 6 includes three interconnected concentric rings, with the diameter of the rings increasing sequentially from the inside to the outside. The sprayer 6 has two layers, both of which are located inside the tower body 1 and are fixedly connected to the inner wall of the tower body 1.

[0051] The defogger 9 consists of two layers, namely a first defogger 91 and a second defogger 92, and both layers of the defogger 9 are located in the middle of the two layers of the sprayer 6.

[0052] Water inlet pipe 10 is fixedly connected to the outside of the tower body 1, and the water inlet pipe 10 is connected to the two-layer sprayers 6.

[0053] The present invention provides two layers of sprayers 6 inside the tower body 1. The sprayer 6 consists of three concentric rings with the diameter of the rings increasing from the inside to the outside, ensuring that the gas inside the entire tower body 1 can be sprayed, greatly reducing the possibility of missed spraying and further ensuring the spraying effect. At the same time, the ammonia water is sprayed out after passing through the three concentric rings with the diameter increasing from the inside to the outside. The ammonia water inside the three concentric rings will be evenly dispersed. The increased spraying range allows the sprayed liquid to fully react with the SO2 in the gas.

[0054] The sprayer 6 includes two layers, an upper sprayer 6 and a lower sprayer 6, and both sprayers 6 are located inside the tower body 1. The tower body 1 also has two layers of demisting fans 9, which are located between the sprayers 6. The sprayers 6 are connected to the water inlet pipe 10 outside the tower body 1.

[0055] When tower 1 starts working, sulfur- and ash-containing gas enters the tower 1 through inlet 2. At the same time, ammonia water in inlet pipe 10 flows into sprayer 6. The ammonia water sprays the gas inside tower 1 through sprayer 6. The ammonia water reacts with SO2 in the gas to remove sulfur and perform the first cleaning of dust in the gas. After the first cleaning, the gas passes through the lower sprayer 6. During the ascent, the gas passes through two layers of demister fans 9. When the gas passes through the demister fans 9, the dust and particles in the gas react with the ammonia water. Due to the inertia of the gas rising, the mixture of particles and ammonia water is adsorbed on the demister fans 9. The dust inside the gas is adsorbed by the demister fans 9 and adheres to them.

[0056] Above the No. 1 demister fan 91 is the upper sprayer 6, which performs secondary cleaning of the gas. On the other hand, the demister fan 9 can also drive the airflow inside the tower body 1 to rise. By cleaning the airflow and driving the airflow upward through the demister fan 9, the working efficiency of the tower body is ensured, while ensuring the desulfurization and ash removal effects. This ensures that the discharged gas meets the emission standards. In addition, the sprayed ammonia water can also clean the dust attached to the demister fan 9, greatly reducing the possibility that the demister fan 9 will fail due to excessive dust accumulation.

[0057] This invention cleans the gas and the demister 9 simultaneously by placing two sprayers 6 above and below the demister 9. The gas is then discharged from the outlet 4 at the top of the tower body 1, while the ammonia sprayed from the sprayers 6 flows into the storage tank 5 at the bottom of the tower body 1. After the tower body 1 finishes operating, the drain port 3 connected to the storage tank 5 can be opened to discharge the ammonia, preventing excessive ammonia buildup from affecting the tower body 1's performance. This invention removes ash and desulfurizes the gas inside the tower body 1, solving the problem that the tower's spraying equipment cannot fully remove SO2 and dust from the gas. Furthermore, by improving the internal structure of the tower, this invention increases its operating efficiency, ensuring that the tower's emissions meet emission standards.

[0058] In one specific embodiment of the present invention, the power assembly includes:

[0059] Motor 11, which is disposed above tower body 1 and fixedly connected to tower body 1;

[0060] A connecting shaft 12 is disposed inside the tower body 1 and is fixedly connected to the output shaft of the motor 11. The connecting shaft 12 is fixedly connected to the demisting fan 9 via the sprayer 6 above.

[0061] Four fixing rods 7 are provided above the air outlet 4, and the fixing rods 7 are fixedly connected to the motor 11 and the tower body 1.

[0062] The present invention has a motor 11 above the tower body 1, and four fixing rods 7 above the air outlet 4. The fixing rods 7 are fixedly connected to the motor 11 and the tower body 1. The output shaft of the motor 11 is fixedly connected to the connecting shaft 12. The connecting shaft 12 is located inside the tower body 1 and is fixedly connected to the output shaft of the motor 11. The connecting shaft 12 is fixedly connected to the demisting fan 9 via the upper sprayer 6.

[0063] When the present invention is working, the motor 11 works, the output shaft of the motor 11 drives the connecting shaft 12 to rotate, and the connecting shaft 12 drives the defogging fan 9 to rotate. On the one hand, the rotation process further increases the contact area with dust in the gas, ensuring that the blades of the defogging fan 9 can fully and evenly contact the dust. Thus, through the rotation of the defogging fan 9, it is ensured that each blade can fully adsorb the dust in the airflow, further improving the dust adhesion effect and reducing the dust content of the exhaust gas.

[0064] On the other hand, the rotation of the defogging fan 9 drives the airflow upward, maintaining the airflow inside the tower body 1 and reducing the excessively fast airflow velocity when the airflow enters through the air inlet 2, which causes the airflow above to not be discharged before the new airflow enters through the air inlet 2, thus causing the airflow inside the tower body to collide and form turbulence, ensuring the normal operation of the tower body 1.

[0065] At the same time, it drives the airflow upward, further improving the working efficiency of the equipment. Meanwhile, the motor 11 is fixed above the tower body 1 by the fixing rod 7 to prevent the motor 11 from being damaged due to excessive temperature, thereby ensuring the normal use of the equipment. Furthermore, the operation of the sprayer 6 can cool the gas inside the equipment, greatly reducing the possibility of direct emission of high temperature gas, and ensuring that the emitted gas will not damage the motor 11 above the tower body 1 due to excessive temperature.

[0066] In one specific embodiment of the present invention, the blades of the first defogger 91 and the second defogger 92 are composed of inclined baffles 8, and there is a gap between adjacent baffles 8. The inclined direction of the baffles 8 inside the second defogger 92 is opposite to that of the first defogger 91. Figures 4 to 6 As shown.

[0067] The defogging fan 9 has two layers and is located inside the tower body 1, between the two sprayers 6. The defogging fan 9 is used to drive the airflow upward and stabilize the air pressure inside the tower body. The blades of the first defogging fan 91 and the second defogging fan 92 are composed of inclined baffles 8, and there is a gap between adjacent baffles 8. The inclined direction of the baffles 8 inside the second defogging fan 92 is opposite to that of the first defogging fan 91. During the upward movement of the gas, it passes through the two layers of defogging fans 9. When the gas passes through the defogging fan 9, the airflow passes through the gap in the middle of the baffles 8. On the one hand, the dust and particles in the gas react with ammonia water. Due to the inertia of the gas rising, the mixture of particles and ammonia water is adsorbed on the baffles 8 of the defogging fan 9. The dust inside the gas is adsorbed by the baffles 8 of the defogging fan 9 and adheres to the defogging fan 9. During the upward movement of the airflow, the direction of movement is upward. By tilting the baffles 8 of the defogging fan 9, the contact area between the airflow and the baffles 8 during the upward movement can be further guaranteed.

[0068] The inclined baffle 8 is used to adsorb dust and particles in the air. Above the defogging fan 9 is the upper sprayer 6, which performs secondary cleaning of the gas. On the other hand, the defogging fan 9 can also drive the airflow inside the tower 1 to rise during rotation, further improving the efficiency of the tower. By using the defogging fan 9 to clean the airflow and drive the airflow to rise, the tower efficiency is improved while ensuring the tower efficiency, thereby ensuring that the tower's emissions can meet the emission standards.

[0069] Furthermore, the baffles 8 inside the two layers of defogging fans 9 have opposite structures. Since the airflow direction of the gas passing through the second defogging fan 92 may be the same as the direction of the gap in the middle of the baffle 8 inside the second defogging fan 92, if the baffles 8 inside the two layers of defogging fans 9 had the same structure, the airflow might move along the direction of the previous gap, thus greatly reducing the cleaning effect of the first defogging fan 91. Therefore, the two layers of baffles 8 have opposite structures to ensure that the airflow direction when passing through the first defogging fan 91 is exactly different from the flow direction when passing through the second defogging fan 92, thereby ensuring sufficient contact between the airflow and the middle of the baffles 8, further ensuring the filtration effect of the defogging fan 9, and further ensuring that the discharged gas can meet the emission standards.

[0070] When the desulfurization tower starts working, the demister fan 9 starts to rotate. During the rotation, while ensuring the airflow and air pressure inside the tower body 1, the baffle 8 of the rotating demister fan 9 comes into further contact with the airflow, which is more conducive to the contact of dust on both sides of the baffle 8, so as to better adsorb and filter the dust and particles in the gas, thereby ensuring the normal operation of the equipment.

[0071] In one specific embodiment of the present invention, a first filter screen 13 is provided inside the tower body 1, and the first filter screen 13 is fixedly connected to the bottom of the connecting shaft 12. The first filter screen 13 is located below the sprayer 6. The connecting shaft 12 has a cavity inside, and a dust removal fan blade 18 is fixedly connected to the top of the connecting shaft 12. A nylon cloth is sleeved on the dust removal fan blade 18, and a through groove is provided inside the dust removal fan blade 18 that communicates with the cavity inside the connecting shaft 12. The through groove inside the dust removal fan blade 18 communicates with the outside. A one-way valve 20 is fixedly connected inside the through groove inside the dust removal fan blade 18. A downwardly inclined water outlet hole 19 is opened on the side of the connecting shaft 12 near the first filter screen 13.

[0072] The No. 1 filter screen 13 is located inside the tower body 1 and below the sprayer 6. During operation, gas enters from the air inlet 2 of the tower body 1, carrying unburned dust and particles. The No. 1 filter screen 13 is used to intercept particles with excessive diameter, thus filtering the gas before purification. This reduces wear on the equipment inside the tower body 1 caused by airflow carrying particles, and also prevents large particles from clogging the apertures of the defogging fan 9 and rendering the equipment unusable. The No. 1 filter screen 13 is fixedly connected to the bottom of the connecting shaft 12. When the connecting shaft 12 rotates, it can drive the No. 1 filter screen 13 to rotate, reducing the possibility of the rotating No. 1 filter screen 13 being clogged. The dust removal fan blade 18, which is fixedly connected to the top of the connecting shaft 12, will also rotate with the rotation of the connecting shaft 12. The gas discharged from the air outlet 4 will pass through the rotating dust removal fan blade 18. The nylon cloth on the dust removal fan blade 18 will further absorb the dust and impurities that have not been removed from the gas, further improving the purity of the gas.

[0073] Most existing tower bodies 1 have climbing ladders around the tower body for convenient daily maintenance. Similarly, in this invention, when the No. 1 filter 13 has been used for a period of time, and the staff uses the climbing ladder to maintain the tower body 1, the motor 11 stops rotating. Water can be carried through the through groove in the dust collector fan blade 18 through the cavity in the connecting shaft 12 and sprayed from the downward-sloping water outlet 19 on the side of the connecting shaft 12 near the No. 1 filter 13, thereby cleaning the No. 1 filter 13 and ensuring its effectiveness. A one-way valve 20 is fixedly connected in the through groove in the dust collector fan blade 18, which can ensure that the water flow can enter the dust collector fan blade 18 from the outside while ensuring that the unfiltered gas flowing in from the water outlet 19 will not flow out of the dust collector fan blade 18 when it flows from the connecting shaft 12 to the dust collector fan blade 18.

[0074] In one specific embodiment of the present invention, the bottom of the storage tank 5 of the tower body 1 is higher at the end away from the drain outlet 3 than at the end near the drain outlet 3.

[0075] The storage tank 5 is located inside the tower body 1 and is connected to the drain port 3. During operation, the storage tank 5 is used to store the ammonia water sprayed by the sprayer 6 and the filtered dust particles. After operation, the ammonia water and filter residue in the storage tank 5 are discharged. In order to facilitate the discharge process and avoid dust accumulation at the bottom of the tower body 1, the bottom of the storage tank 5 is higher at the end away from the drain port 3 than at the end near the drain port 3, which makes it easier for the staff to carry out the discharge and cleaning work, ensuring the cleanliness of the bottom of the tower body 1, thereby ensuring the normal operation of the equipment.

[0076] In one specific embodiment of the present invention, the tower body 1 is provided with two atomizers 14, and the two atomizers 14 are disposed between the sprayer 6 and the air outlet 4, and are fixedly connected to the connecting shaft 12.

[0077] The tower body 1 is equipped with an atomizer 14, which is located above the sprayer 6 and fixedly connected to the connecting shaft 12. During operation, high-temperature, dusty, and sulfur-containing gas enters the tower body 1 through the air inlet 2. After being purified by the sprayer 6 and the demisting fan 9, most of the dust and sulfur-containing substances are cleaned away. In order to further ensure that the dust content in the exhaust gas meets the emission standards, the dust is atomized by the atomizer 14 above the upper sprayer 6. The dust in the gas mixes with the water mist and settles. At the same time, the atomizer 14 further reduces the temperature of the gas to prevent the gas temperature inside the tower body 1 from being too high and affecting the use of the equipment.

[0078] In one specific embodiment of the present invention, twenty-six nozzles 15 are fixedly connected to the bottom of the sprayer 6 and the nozzles 15 are interconnected with the sprayer 6, and the nozzles of the nozzles 15 are flat.

[0079] The sprayer 6 consists of three concentric rings with increasing diameter from the inside out. The sprayer 6 comprises two layers: an upper sprayer 6 and a lower sprayer 6, both located inside the tower body 1. To further ensure the spraying effect of the sprayer 6, twenty-six nozzles 15 are fixedly connected below the sprayer 6. The number of nozzles 15 on the rings is six, eight, and twelve respectively, arranged from the inside out, and evenly distributed across the sprayer 6. This ensures that most of the gas inside the tower body 1 is cleaned when passing through the sprayer 6. The nozzles of the nozzles 15 are flat, ensuring that the sprayed ammonia water forms a fan shape, guaranteeing sufficient contact between the SO2 and ash layer in the liquid and gas, further ensuring a more complete reaction between the gas and ammonia water, and ensuring the normal operation of the tower body 1.

[0080] In one specific embodiment of the present invention, the defogging fan 9 is made of polytetrafluoroethylene.

[0081] During operation, the gas enters at a high temperature through the air inlet 2. To ensure that the equipment is not damaged, the defogging fan 9 is made of polytetrafluoroethylene (PTFE). On the one hand, the material is lighter, which greatly reduces the pressure on the motor 11. On the other hand, the material can withstand high temperatures, avoiding the possibility of equipment damage due to high temperatures. Furthermore, sulfur-containing gas mixed with ammonia water is corrosive, and PTFE has good corrosion resistance, further ensuring the integrity of the equipment and making it more conducive to long-term operation.

[0082] In one specific embodiment of the present invention, the drain outlet 3 is connected to the wastewater pool 17 and the wastewater pool 17 is located outside the tower body 1. A second filter screen 16 is provided in the middle of the wastewater pool 17 and the second filter screen 16 is fixedly connected to the wastewater pool 17.

[0083] The drain outlet 3 is located on the right side of the tower body 1. The wastewater pool 17 is located outside the tower body 1, and the drain outlet 3 is connected to the wastewater pool 17. The wastewater pool 17 is equipped with a second filter screen 16, which is fixedly connected to the wastewater pool 17. The waste liquid flowing down from the cleaning process is discharged into the wastewater pool 17 through the drain outlet 3, and the waste liquid is filtered through the second filter screen 16, so that the bottom of the wastewater pool is the filtered waste liquid. The wastewater from the tower body 1 is (NH4)2SO4, which can be recycled for medical, leather and other applications, ensuring resource utilization.

[0084] Working principle: The present invention has two layers of sprayers 6 inside the tower body 1. The sprayer 6 consists of three concentric rings with the diameter of the rings increasing from the inside to the outside, ensuring that the gas inside the entire tower body 1 can be sprayed, thus ensuring the spraying effect. At the same time, ammonia water is sprayed out after passing through the three concentric rings with the diameter increasing from the inside to the outside. The ammonia water inside the three concentric rings will be evenly dispersed. The increased spraying range allows the sprayed liquid to fully react with SO2 in the gas.

[0085] The sprayer 6 includes two layers, an upper sprayer 6 and a lower sprayer 6, and both sprayers 6 are located inside the tower body 1. The tower body 1 also has two layers of demisting fans 9, which are located between the sprayers 6. The sprayers 6 are connected to the water inlet pipe 10 outside the tower body 1.

[0086] When tower 1 starts working, sulfur- and ash-containing gas enters the tower 1 through inlet 2. Simultaneously, ammonia water from inlet pipe 10 flows into sprayer 6. The ammonia water sprays the gas inside tower 1 through sprayer 6, reacting with the SO2 in the gas to remove sulfur and perform the first cleaning of dust. After the first cleaning, the gas passes through the lower sprayer 6 and then through two layers of demister fans 9 as it rises. As the gas passes through the demister fans 9, it is partially evaporated. The dust and particles in the gas react with ammonia water. Due to the inertia of the gas, the mixture of particles and ammonia water is adsorbed onto the demister fan 9. The dust inside the gas is adsorbed by the demister fan 9 and adheres to the demister fan 9. Above the first demister fan 91 is the upper sprayer 6, which performs secondary cleaning of the gas. On the other hand, the demister fan 9 can also drive the airflow inside the tower body 1 to rise. By using the demister fan 9 to clean the airflow and drive the airflow to rise, the working efficiency of the tower body is ensured, while ensuring the desulfurization and ash removal effects, thereby ensuring that the discharged gas meets the emission standards.

[0087] Furthermore, the sprayed ammonia water can also clean the dust adhering to the demister fan 9, greatly reducing the possibility of the demister fan 9 failing due to excessive dust adhering to it. By setting two layers of sprayers 6 above and below the demister fan 9 respectively, the demister fan 9 can be cleaned while the gas is being cleaned. Finally, the gas is discharged from the outlet 4 at the top of the tower body 1, while the ammonia water sprayed by the sprayers 6 flows into the storage tank 5 at the bottom of the tower body 1. When the tower body 1 finishes working, the drain port 3 connected to the storage tank 5 can be opened to discharge the ammonia water inside the storage tank 5, preventing excessive accumulation of ammonia water from affecting the effect of the tower body 1.

[0088] This invention solves the problem that the spray equipment in the tower cannot fully remove SO2 and dust from the gas by removing ash and desulfurizing the gas inside the tower body 1. This invention improves the working efficiency of the tower by improving the internal structure of the tower body, thereby ensuring that the emissions of the tower body can meet the emission standards.

[0089] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
