Technical Field
[0001] This utility model relates to the field of absorbent ratio technology, specifically to an adjustable wet desulfurization flue gas purification device with an adjustable absorbent ratio. Background Technology
[0002] Currently, steel enterprises rank second in total industrial waste gas emissions nationwide, accounting for approximately 28%, with emissions of about 1.8 million to 2.2 million tons per year, second only to coal-fired power generation. SO2 and NOx emissions from steel production enterprises mainly originate from sintering and coking processes.
[0003] Wet desulfurization technology is widely used in metallurgy, chemical industry, waste incineration, power industry, and other fields. It involves atomizing an alkaline solution with a spray liquid, which reacts with harmful substances in the flue gas to generate sulfates or sulfites, and then traps particulate matter. Wet desulfurization is a commonly used technology for treating sulfur dioxide pollutants. It requires the addition of an absorbent to the industrial flue gas, which removes sulfur dioxide through an absorption reaction, thus achieving desulfurization. The absorbent is crucial in the wet desulfurization process, effectively removing sulfur dioxide from the flue gas and achieving emission reduction goals; its purity significantly affects the desulfurization effect and equipment lifespan.
[0004] However, in existing devices, various materials are directly poured into the device, making it impossible to mix them in a certain proportion, resulting in uneven mixing. Furthermore, clumps formed without sufficient stirring will fall directly into the device due to their own gravity. These clumps cannot be fully stirred and broken up, affecting the quality of the subsequent finished product. To address these issues, we propose an adjustable absorbent wet desulfurization flue gas purification device with an adjustable absorbent ratio. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This utility model, through the setting of the batching mechanism, pours the absorbent and the material into two sets of feed pipes respectively. By observing the scale lines on the surface of the feed pipe, the appropriate ratio is adjusted. At this time, the discharge port channel is blocked. After the adjustment is completed, the first motor is driven. The first bevel gear and the first driven gear mesh with each other, so that the first bevel gear drives the first driven gear and the connecting plate to rotate, so that the position of the discharge port overlaps with the feed pipe. The adjusted absorbent and material enter the proportioning cylinder, which facilitates the reasonable proportion adjustment of the material before mixing and avoids different proportions from affecting the mixing effect.
[0016] 2. This utility model, through the setting of a synchronization mechanism, uses a first motor to drive a first bevel gear to rotate. When the discharge port at the connecting plate is opened, the first driving wheel and the first synchronous belt drive the second bevel gear to rotate, causing the second driven gear to rotate. The second bevel gear and the second driven gear mesh with each other, causing the discharge hole at the second partition to overlap with the discharge hole at the upper first partition. Conversely, when the discharge port is closed, the discharge holes at the first and second partitions overlap. The baffle can stir and mix the material on the first partition. After the mixture is evenly stirred, the scraper pushes the material, causing the evenly stirred material to fall into the outer shell from the discharge holes at the first and second partitions. This avoids the material entering the mixing drum before it is evenly mixed, which would affect the quality of the finished product. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-6This utility model provides an embodiment of an adjustable absorbent wet desulfurization flue gas purification device, comprising a housing 1, a proportioning cylinder 2 fixedly installed at the top of the housing 1, a proportioning mechanism 3 provided at the top of the proportioning cylinder 2, and the proportioning mechanism 3 comprising a feed pipe 31, a fixed box 32, a first motor 33, a first drive wheel 34, a first bevel gear 35, a first driven gear 36, a connecting plate 37, and a discharge port 38.
[0027] The top of the mixing cylinder 2 is provided with two sets of feed pipes 31. A fixed box 32 is installed on the outside of the mixing cylinder 2. A first motor 33 is fixedly installed inside the fixed box 32. A first drive wheel 34 is provided on the left side of the first motor 33. A first bevel gear 35 is provided on the left side of the first drive wheel 34. A first driven gear 36 is provided inside the mixing cylinder 2. A connecting plate 37 is provided on the inside of the first driven gear 36. Two sets of discharge ports 38 are opened in the connecting plate 37.
[0028] This device, through the setting of proportioning mechanism 3 and linkage component 4, solves the problem of uneven mixing caused by the inability to mix materials in a certain proportion; and the problem that clumps formed without sufficient mixing will fall directly into the device due to their own gravity. These clumps cannot be fully mixed and dispersed, which affects the quality of the subsequent finished products.
[0029] Furthermore, a linkage assembly 4 is provided at the bottom of the mixing cylinder 2. The linkage assembly 4 includes a first rotating shaft 41, a first driven wheel 42, a first synchronous belt 43, a second bevel gear 44, a second driven gear 45, a first partition 46, a second partition 47, and a discharge hole 48. The bottom of the fixed box 32 is rotatably connected to the first rotating shaft 41. The first driven wheel 42 is fixedly connected to the outside of the first rotating shaft 41. The first synchronous belt 43 is movably connected to the outside of the first driven wheel 42. The other side of the first synchronous belt 43 is sleeved on the first driving wheel 3. On the outer side of 4, a second bevel gear 44 is fixedly connected to the left end of the first driven wheel 42.

A first partition 46 is fixedly connected to the bottom of the proportioning cylinder 2. A second partition 47 is provided below the first partition 46. The outer surface of the second partition 47 is fixedly connected to the second driven gear 45. Discharge holes 48 are equidistantly opened on the surfaces of the first partition 46 and the second partition 47. (The text abruptly ends here.) Figure 4As shown, this structure is used to close the discharge port 38 by driving the first drive wheel 34 through the first motor 33, so that the first driven wheel 42 rotates through the first rotating shaft 41 and the first synchronous belt 43, driving the second bevel gear 44 to rotate. The second bevel gear 44 and the second driven gear 45 mesh with each other, so that the second driven gear 45 drives the second partition 47 to rotate, so that the discharge hole 48 at the second partition 47 overlaps with the discharge hole 48 at the first partition 46, so that the mixed material in the mixing cylinder 2 enters the outer shell 1 through the discharge hole 48.
[0030] Furthermore, the bottoms of the two sets of feed pipes 31 are fixedly connected to the proportioning cylinder 2. The output end of the first motor 33 is fixedly connected to the first driving wheel 34. The right end of the first bevel gear 35 is fixedly connected to the first driving wheel 34. The outer side of the connecting plate 37 is fixedly connected to the first driven gear 36. The top of the proportioning cylinder 2 is rotatably connected to the first driven gear 36. The first driven gear 36 is located above the first bevel gear 35 and meshes with it. The diameter of the discharge port 38 is the same as the opening diameter of the feed pipe 31. Figure 3 As shown, this structure is used to mix the absorbent and the material by placing them into two sets of feed pipes 31 respectively. The absorbent and the material are proportioned through the feed pipes 31. At this time, the outlet 38 is blocked. After the mixing is completed, the first motor 33 is driven. The first bevel gear 35 meshes with the first driven gear 36, causing the first bevel gear 35 to drive the first driven gear 36 and the connecting plate 37 to rotate. The outlet 38 is aligned with the feed pipe 31, and the mixed absorbent and material enter the proportioning cylinder 2. This facilitates the reasonable proportioning of the materials before mixing and avoids different proportions affecting the mixing effect.
[0031] Furthermore, a mixing assembly 5 is provided at the bottom of the mixing cylinder 2. The mixing assembly 5 includes a second motor 51, a second drive wheel 52, a second synchronous belt 53, a second rotating shaft 54, a stirring plate 55, and a second driven wheel 56. The second motor 51 is installed on the outside of the mixing cylinder 2. The lower end of the second motor 51 is fixedly connected to the second drive wheel 52. The outer side of the second drive wheel 52 is movably connected to the second synchronous belt 53. The second rotating shaft 54 is rotatably connected to the first partition 46 via bearings. The stirring plate 55 is fixedly connected to the top outer side of the second rotating shaft 54. The lower end of the second rotating shaft 54 is fixedly connected to the second driven wheel 56. The other side of the second synchronous belt 53 is movably connected to the second driven wheel 56. Figure 2 As shown, this structure is used to break up the clumps of material in the mixing cylinder 2 by starting the second motor 51, which drives the second drive wheel 52 to rotate, and under the action of the second synchronous belt 53, drives the second driven wheel 56 and the stirring plate 55 to rotate.
[0032] Furthermore, an anti-clogging component 6 is provided inside the stirring plate 55. The anti-clogging component 6 includes a movable groove 61, a movable rod 62, a scraper 63, and a spring 64. The mixing component 5 has a movable groove 61, and two sets of movable rods 62 are movably connected inside the movable groove 61. The lower end of the movable rod 62 is fixedly connected to the scraper 63, and a spring 64 is provided inside the movable rod 62. The two ends of the spring 64 abut against the inner wall of the movable rod 62 and the movable groove 61, respectively. Figure 6 As shown, this structure is used to move the scraper 63 against the surface of the first partition 46 under the elastic action of the spring 64 when the stirring plate 55 rotates, so as to prevent material from accumulating on the surface of the first partition 46.
[0033] Furthermore, limit rings are fixedly connected to the outer sides of both the first driven gear 36 and the second driven gear 45, and the inner wall of the proportioning cylinder 2 is provided with a sliding groove that matches the limit ring. Figure 3 As shown, this structure is used to stabilize the first driven gear 36 and the second driven gear 45 within the proportioning cylinder 2 for rotation via a limiting ring.
[0034] Furthermore, the cross-section at the edge of scraper 63 is triangular. For example... Figure 6 As shown, this structure is used to guide and clean the material on the surface of the first partition 46 using a scraper 63.
[0035] Working principle: When using, such as Figure 1 and Figure 3 As shown, the absorbent and material are first poured into the two sets of feed pipes 31 respectively. The appropriate ratio is adjusted by observing the scale lines on the surface of the feed pipes 31. At this time, the outlet 38 is blocked. After the adjustment is complete, the first motor 33 is driven. The first bevel gear 35 meshes with the first driven gear 36, causing the first bevel gear 35 to drive the first driven gear 36 and the connecting plate 37 to rotate, aligning the outlet 38 with the feed pipe 31. The adjusted absorbent and material then enter the mixing cylinder 2, facilitating a reasonable ratio adjustment of the materials before mixing and avoiding different ratios affecting the mixing effect. Figure 2 As shown, after the material and absorbent enter the mixing cylinder 2, the second motor 51 is started. The second motor 51 drives the second drive wheel 52 to rotate, which in turn drives the second driven wheel 56 and the stirring plate 55 to rotate under the action of the second synchronous belt 53. This breaks up the clumps of material in the mixing cylinder 2 and fully mixes the material and absorbent. Figure 3 and Figure 4As shown, while the first motor 33 drives the first driving wheel 34 to close the discharge port 38, the first driven wheel 42 rotates through the first rotating shaft 41 and the first synchronous belt 43, driving the second bevel gear 44 to rotate. The second bevel gear 44 and the second driven gear 45 mesh with each other, causing the second driven gear 45 to drive the second partition 47 to rotate, so that the discharge hole 48 at the second partition 47 overlaps with the discharge hole 48 at the first partition 46, so that the mixed material in the mixing cylinder 2 enters the outer shell 1 through the discharge hole 48 under the action of the stirring plate 55. The above is the complete working principle of this utility model.
[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
