Description

Technical Field

[0001] This utility model relates to the field of desulfurization technology, and more specifically, it relates to a dust removal device for desulfurization. Background Technology

[0002] Desulfurization refers to the process of removing sulfur elements or sulfides from substances through physical and chemical methods. It is mainly applied in fields such as industrial production, environmental protection, and energy utilization, such as reducing the sulfur content in fuels such as petroleum and coal, reducing the emission of harmful gases such as sulfur dioxide produced after combustion, thereby mitigating environmental pollution problems such as acid rain.

[0003] In the wet desulfurization process, dust particles in the flue gas can cause wear and blockage of the desulfurization equipment, reduce desulfurization efficiency, and affect the quality of the final flue gas emissions and subsequent slurry treatment. Therefore, dust removal devices are needed to remove a large amount of dust from the flue gas during the desulfurization process to ensure the normal operation of the desulfurization equipment, improve desulfurization efficiency, meet environmental emission requirements, and reduce the burden of subsequent treatment.

[0004] However, during the dust removal process, a large amount of dust in the flue gas gradually adheres to the filter screen used for dust removal, causing the filter screen pores to gradually become smaller, obstructing the flow of flue gas, and eventually leading to filter screen blockage. This not only affects the dust removal efficiency but also has a negative impact on the desulfurization efficiency, and may even cause equipment failure and increased energy consumption. Therefore, a dust removal device for desulfurization is proposed to improve the existing problems. Utility Model Content

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0024] Please see Figures 1-7 The present invention provides the following technical solution:

[0025] Example 1, see Figures 1-7 A desulfurization dust removal device includes a desulfurization dust removal tank 1, a liquid storage tank 2 on one side of the desulfurization dust removal tank 1, a first pipe 3 on the top of the liquid storage tank 2, a plurality of second pipes 4 on the side wall of the top of the first pipe 3, the second pipes 4 penetrating the side wall of the desulfurization dust removal tank 1, a plurality of spray heads 5 on the side wall of the second pipes 4, a first cylinder 6 symmetrically arranged below the spray heads 5, a first filter screen 7 between two sets of first cylinders 6, the output end of the first cylinder 6 connected to the first filter screen 7, a second filter screen 8 below the first filter screen 7, and a telescopic rod 9 slidably connected to the bottom of the second filter screen 8.

[0026] The desulfurization and dust removal tank 1 is mainly used to contain the flue gas to be treated. The storage tank 2 stores and provides the solution for spraying, ensuring that there is a sufficient liquid supply. The first pipe 3 transports the solution in the storage tank 2 to the second pipe 4, and then sprays it evenly through multiple sets of spray heads 5 set on the side of the second pipe 4, effectively covering the inside of the desulfurization and dust removal tank 1 to achieve desulfurization treatment of the flue gas. Below the spray head 5, a pair of components working together are set up: a first cylinder 6 and a first filter screen 7. When the first cylinder 6 extends and retracts, it can drive the first filter screen 7 to move up and down and contact or separate from the second filter screen 8. The second filter screen 8 is used for the first step of dust removal of the flue gas. The telescopic rod 9 below the second filter screen 8 works together with the second cylinder 10. The output end of the second cylinder 10 extends and retracts to control the movement of the telescopic rod 9, and the telescopic rod 9 adapts to the second filter screen 8 to adjust its length.

[0027] When the flue gas desulfurization operation starts, the flue gas passes through the second filter screen 8 and the first filter screen 7 in sequence to complete dust removal. Subsequently, the solution released by the spray head 5 comes into full contact with the flue gas, undergoing a chemical reaction to achieve the desulfurization effect. As the operation continues, the dust accumulation on the second filter screen 8 and the first filter screen 7 increases. At this time, the first cylinder 6 starts, driving the first filter screen 7 to move down and fit against the second filter screen 8. Because the meshes of the two filter screens are misaligned, after contact, the dust particles on the first filter screen 7 are squeezed out by the second filter screen 8, and the dust particles on the second filter screen 8 are then... First, filter screen 7 is squeezed out. Then, first cylinder 6 retracts, separating the two filter screens. Dust particles from second filter screen 8 and first filter screen 7 are directly washed down to the bottom of desulfurization and dust removal tank 1 by spraying from spray head 5. Finally, second cylinder 10 below second filter screen 8 is activated, and its output end drives the connected telescopic rod 9 to move. At the same time, telescopic rod 9 also starts to self-adjust and extend. Through the coordinated work of second cylinder 10 and telescopic rod 9, residual dust on second filter screen 8 is cleaned, ensuring continuous unobstructed flow of the filter screen and maintaining efficient system operation.

[0028] Through the coordinated operation of the first cylinder 6, the second cylinder 10, and the telescopic rod 9, the filter screen is cleaned efficiently and dust is removed, thereby improving dust removal and desulfurization efficiency and effectively preventing equipment failure and energy consumption increase.

[0029] See Figures 1-7 Furthermore, a second cylinder 10 is provided on one side of the telescopic rod 9. The output end of the second cylinder 10 passes through the side wall of the desulfurization and dust removal tank 1 and is connected to the telescopic rod 9.

[0030] The output end of the second cylinder 10 extends and retracts, driving the telescopic rod 9 to slide. In conjunction with the telescopic rod 9's own extension and retraction function, it achieves comprehensive scraping of the second filter screen 8, ensuring the cleanliness of the filter screen.

[0031] See Figures 1-7 Furthermore, the bottom of the desulfurization and dust removal tank 1 is provided with multiple sets of support frames 11, which are equidistantly arranged.

[0032] The bottom of the desulfurization and dust removal tank 1 is supported by multiple sets of support frames 11. Each set of support frames 11 is equidistant, which enhances the stability of the desulfurization and dust removal tank, effectively distributes the load, and avoids damage caused by overload of a single support point.

[0033] See Figures 1-7 Furthermore, the bottom of the desulfurization and dust removal tank 1 is provided with a waste outlet 12, and the side wall of the waste outlet 12 is provided with a first check valve 121.

[0034] The waste outlet 12 at the bottom of the desulfurization and dust removal tank 1 is used to discharge the treated waste. The first check valve 121 on its side wall can close the waste outlet 12 when needed to prevent waste leakage and ensure operational safety.

[0035] See Figures 1-7 Furthermore, the desulfurization and dust removal tank 1 has a flue gas inlet 13 on its side wall, which is located below the telescopic rod 9.

[0036] The desulfurization and dust removal tank 1 has a flue gas inlet 13 on its side wall, located below the telescopic rod 9. When the flue gas enters the desulfurization and dust removal tank 1 through this flue gas inlet 13, it must pass through the first filter screen 7 and the second filter screen 8 located above the telescopic rod 9 before it can be discharged smoothly. This design ensures that the flue gas must be fully filtered before being discharged, thereby effectively guaranteeing the filtration effect.

[0037] See Figures 1-7 Furthermore, the top of the desulfurization and dust removal tank 1 is provided with an air outlet 14, which is cone-shaped.

[0038] The conical design guides the gas smoothly out of the tank while reducing the impact of the airflow on the top of the tank, thereby improving the dust removal effect and extending the service life of the equipment.

[0039] See Figures 1-7 Furthermore, a third check valve 31 is provided on the side wall of the first pipe 3, and a second check valve 41 is provided on the side wall of the second pipe 4.

[0040] The third check valve 31 is located on the side wall of the first pipe 3. Its main function is to provide reliable switching control when it is necessary to cut off or open the flow of solution in the first pipe 3. Similarly, the second check valve 41 is located on the side wall of the second pipe 4. Its function is similar to that of the third check valve 31, and it is used to control the flow of solution in the second pipe 4.

[0041] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
