Description

Technical Field

[0001] This utility model relates to the field of desulfurization, denitrification and dust removal technology, specifically a desulfurization and denitrification flue gas dust treatment mechanism. Background Technology

[0002] When using a flue gas desulfurization tower, a desulfurizing agent needs to be prepared. The desulfurizing agent is generally stored in a silo. The desulfurizing agent generally refers to the agent that removes free sulfur or sulfur compounds from fuel, raw materials or other materials. In the control and treatment of pollutants, it mainly refers to the agent that can remove sulfur oxides (including SO2 and SO3) from the exhaust gas. Various alkaline compounds can be used as desulfurizing agents to remove sulfur dioxide from flue gas.

[0003] Currently, when unloading desulfurizing agents, it is necessary to manually climb to the top of the silo, open the ton bag containing the desulfurizing agent, and unload the desulfurizing agent into the silo. This operation is inconvenient, time-consuming, labor-intensive, and has low safety. During unloading, smoke and dust are seriously emitted, and there is a lot of dust accumulation at the work site, which cannot meet environmental protection requirements.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0005] The purpose of this invention is to solve the above problems by designing a desulfurization and denitrification flue gas treatment mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A desulfurization and denitrification flue gas treatment mechanism includes a silo body. The inlet of the silo body is connected to a feed hopper. An inclined support rod is installed on the inner wall of the feed hopper. A hollow cylinder is installed at the end of the inclined support rod away from the feed hopper. Three inclined angle steels are installed around the top of the hollow cylinder. The tops of the three inclined angle steels are fixedly connected. A dust removal pipe is connected to one side of the top of the silo body. A transverse pipe is connected between the dust removal pipe and the feed hopper. A filter screen is installed at the vertical arm end of the dust removal pipe, and the filter screen is located above the transverse pipe.

[0008] Furthermore, a sealed bearing is connected to the cross arm end of the dust removal pipe. The outer ring of the sealed bearing is fixedly connected to the dust removal pipe. A connecting shaft is installed inside the inner ring of the sealed bearing. The bottom end of the connecting shaft passes through the filter screen. Two cleaning rods are installed on the connecting shaft. The two cleaning rods are located at the upper and lower ends of the filter screen, respectively. Cleaning brushes are installed on the two cleaning rods, and the cleaning brushes are in contact with the filter screen.

[0009] Furthermore, a first valve is installed on the dust removal pipe, which is located below the horizontal pipe, and a second valve is installed on the horizontal pipe.

[0010] Furthermore, a driven gear is installed at the top of the connecting shaft, and shaft fixing seats are installed on the hopper body and the dust removal pipe. A drive shaft is rotatably connected to the shaft fixing seat. The two ends of the drive shaft pass through the two shaft fixing seats respectively. A drive gear is installed at the top of the drive shaft. The drive gear meshes with the driven gear. A rotating handle is installed at the bottom of the drive shaft.

[0011] Furthermore, four inclined support rods are provided. One end of the inclined support rod is fixedly connected to the inner wall of the feed hopper, and the other end of the inclined support rod is fixedly connected to the outer wall of the hollow cylinder. The tops of the three inclined angle steels are inclined towards the center of the hollow cylinder, and the tops of the three inclined angle steels are sharp angles.

[0012] Compared with existing technologies, this technical solution has the following beneficial effects:

[0013] The bottom of the ton bag is pierced by the top of three inclined angle steels, and the desulfurizing agent inside the ton bag falls into the feed hopper. No manual unloading is required, which is convenient and safe to operate. The dust generated during unloading is discharged through the dust removal pipe and the horizontal pipe, which prevents the dust from escaping during unloading, reduces the dust accumulation on site, and improves the site environment. The filter screen prevents the desulfurizing agent particles from being sucked in.

[0014] The filter screen is cleaned by a cleaning brush, which removes impurities and prevents the filter screen from clogging, thus improving dust removal efficiency. Operators do not need to climb onto the hopper body to rotate the cleaning rod and cleaning brush, which avoids falling from height and improves safety.

[0015] The hollow cylinder and the inclined angle steel are supported by four diagonal support rods, which improves stability. The tops of the three inclined angle steels are sharp, which makes it easy to tie the ton bag through the opening and facilitates unloading. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] This utility model provides, for example Figure 1-4 The desulfurization and denitrification dust treatment mechanism shown includes a silo body 1, a feed hopper 2 connected to the feed inlet of the silo body 1, a diagonal support rod 3 installed on the inner wall of the feed hopper 2, a hollow cylinder 4 installed at the end of the diagonal support rod 3 away from the feed hopper 2, three diagonal angle steels 5 installed around the top of the hollow cylinder 4, the tops of the three diagonal angle steels 5 being fixedly connected, a dust removal pipe 6 connected to one side of the top of the silo body 1, a transverse pipe 7 connected between the dust removal pipe 6 and the feed hopper 2, a filter screen 8 installed at the vertical arm end of the dust removal pipe 6, the filter screen 8 being located above the transverse pipe 7.

[0024] When unloading the desulfurizing agent, an electric hoist is used to lift the ton bag containing the desulfurizing agent and move it below the feed hopper 2. The ton bag is then lowered until its bottom end contacts the top of the three inclined angle steels 5. The bottom of the ton bag is then pierced through the inclined angle steels 5, allowing the desulfurizing agent inside to fall into the feed hopper 2. The hollow cylinder 4 is hollow inside, and the desulfurizing agent entering the hollow cylinder 4 falls into the feed hopper 2. The desulfurizing agent falling into the feed hopper 2 then enters the silo body 1. No manual unloading is required, making the operation convenient. For safety, the dust removal pipe 6 starts working during unloading. The dust removal pipe 6 is existing technology and will not be described in detail. A negative pressure is generated inside the dust removal pipe 6. The dust generated in the hopper body 1 is sucked out through the dust removal pipe 6. The dust generated in the feed hopper 2 is sucked into the dust removal pipe 6 through the horizontal pipe 7. The dust generated is discharged through the dust removal pipe 6 to prevent dust from escaping during unloading, reduce dust accumulation on site, and improve the site environment. The filter screen 8 prevents the desulfurizing agent particles from being sucked in.

[0025] Refer to the instruction manual appendix Figure 3 Included with instruction manual Figure 4 A sealed bearing 9 is connected to the cross arm end of the dust removal pipe 6. The outer ring of the sealed bearing 9 is fixedly connected to the dust removal pipe 6. A connecting shaft 10 is installed inside the inner ring of the sealed bearing 9. The bottom end of the connecting shaft 10 passes through the filter screen 8. Two cleaning rods 11 are installed on the connecting shaft 10. The two cleaning rods 11 are located at the upper and lower ends of the filter screen 8, respectively. Cleaning brushes 12 are installed on the two cleaning rods 11 and contact the filter screen 8.

[0026] Rotating the connecting shaft 10 causes the inner ring of the sealed bearing 9 to rotate along the outer ring. The connecting shaft 10 also causes the two cleaning rods 11 to rotate, which in turn causes the cleaning brush 12 to rotate. The cleaning brush 12 cleans the filter screen 8, removing impurities from the filter screen 8 and preventing the filter holes of the filter screen 8 from becoming clogged, thus improving dust removal efficiency.

[0027] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 A first valve 13 is installed on the dust removal pipe 6. The first valve 13 is located below the horizontal pipe 7. A second valve 14 is installed on the horizontal pipe 7.

[0028] After the material in the ton bag is unloaded and the dust in the feed hopper 2 is discharged, the second valve 14 is closed, and the dust in the silo body 1 is discharged through the dust removal pipe 6. After the dust is discharged, the first valve 13 is closed.

[0029] Refer to the instruction manual appendix Figure 1A driven gear 15 is installed at the top of the connecting shaft 10. A shaft fixing seat 16 is installed on the hopper body 1 and the dust removal pipe 6. A drive shaft 17 is rotatably connected to the shaft fixing seat 16. The two ends of the drive shaft 17 pass through the two shaft fixing seats 16 respectively. A drive gear 18 is installed at the top of the drive shaft 17. The drive gear 18 meshes with the driven gear 15. A rotating handle 19 is installed at the bottom of the drive shaft 17.

[0030] The drive shaft 17 can be easily rotated by turning the handle 19. The drive shaft 17 rotates on the two shaft fixing seats 16. The drive shaft 17 drives the drive gear 18 to rotate. The drive gear 18 meshes with the driven gear 15. The drive gear 18 drives the driven gear 15 and the connecting shaft 10 to rotate. The operator does not need to climb up the hopper body 1 to rotate the cleaning rod 11 and the cleaning brush 12, which avoids the operator falling from a height and improves safety.

[0031] Refer to the instruction manual appendix Figure 2 Four inclined support rods 3 are provided. One end of the inclined support rod 3 is fixedly connected to the inner wall of the feed hopper 2, and the other end of the inclined support rod 3 is fixedly connected to the outer wall of the hollow cylinder 4. The tops of the three inclined angle steels 5 are inclined towards the center of the hollow cylinder 4, and the tops of the three inclined angle steels 5 are sharp angles.

[0032] The hollow cylinder 4 and the inclined angle steel 5 are supported by four diagonal support rods 3, which improves stability. The tops of the three inclined angle steels 5 are sharp, which makes it easy to tie the ton bag through the opening and facilitates unloading.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
