Description

Technical Field

[0001] This invention relates to the field of desulfurization equipment, and in particular to a desulfurization device. Background Technology

[0002] With the acceleration of global industrialization, the emission of large amounts of sulfur-containing gases has posed a severe challenge to the ecological environment and human health. Sulfur-containing gases mainly originate from the combustion of fossil fuels (such as coal and oil) and some chemical production processes. If they are emitted directly without effective treatment, they will lead to environmental problems.

[0003] Regarding the distribution of desulfurizing agents, many desulfurization devices may not be able to distribute the desulfurizing agent evenly and sufficiently within the tower. Some devices use a simple dosing method, resulting in uneven distribution of the desulfurizing agent within the tower. This leads to excessively high concentrations of desulfurizing agent in some areas, causing waste and poor desulfurization effect. This uneven distribution limits the contact area between the gas and the desulfurizing agent, resulting in insufficient reaction time and significantly reducing desulfurization efficiency. Secondly, when the desulfurizing agent is transported in pipelines, blockages and accumulation are prone to occur. For example, when the desulfurizing agent has high humidity or uneven particle size, it may adhere to the inner wall of the pipeline during pneumatic conveying, gradually accumulating and causing pipeline blockage, affecting the continuous and stable operation of the device. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and propose a desulfurization device to solve the problems of the desulfurizing agent not being able to be evenly distributed and fully dispersed in the tower and the desulfurizing agent clogging the delivery pipeline in the above-mentioned technical solutions.

Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0037] Example:

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the present invention provides a technical solution: a desulfurization device, including a tower body 1, a frame 2, a transmission component 4 for conveying waste, an anti-deposition component 5 for filtering sulfur-containing gases, and a transmission component 7 for transmitting power. The frame 2 is located below the tower body 1. The bottom of the tower body 1 has a gradually decreasing opening from top to bottom. A desulfurization component 3 is installed inside the tower body 1 to desulfurize the sulfur-containing gases inside the tower body 1. The transmission component 4 is installed on the frame 2. The anti-deposition component 5 is installed at the bottom of the tower body 1, above the transmission component 4. An outlet pipe 8 is fixedly connected to the outer side of the top of the tower body 1, located on the right side of the top of the tower body 1. An inlet pipe 9 is fixedly connected to the outer side of the bottom of the tower body 1, located on the left side of the bottom of the tower body 1. A pretreatment component 6 is installed at the end away from the tower body 1. The pretreatment component 6 separates impurities in the sulfur-containing gas. The pretreatment component 6 is located above the anti-deposition component 5. A second valve 10 is fixed at the bottom of the tower body 1. A vibration component 11 is installed on the outer side of the bottom of the tower body 1. The vibration component 11 continuously loosens the deposits at the bottom of the tower body 1. The second valve 10 facilitates the discharge of desulfurization products at the bottom of the tower body 1. The sulfur-containing gas is transmitted to the interior of the tower body 1 through the pretreatment component 6 and the inlet pipe 9. The desulfurization component 3 desulfurizes the gas. The second valve 10 allows the desulfurization products to be transmitted to the interior of the frame 2. The transmission component 7 transmits power. The anti-deposition component 5 stirs the bottom of the tower body 1 to prevent the products from accumulating at the bottom of the tower body 1. The pretreatment component 6 separates impurities in the sulfur-containing gas.

[0039] The desulfurization component 3 includes an annular plate 31 fixed to the inner wall of the tower body 1. A gas distributor is installed inside the tower body 1, corresponding to the annular plate 31. Four annular plates 31 are arranged sequentially from top to bottom inside the tower body 1, creating multiple desulfurization zones within the tower body 1. A spring 32 is fixedly connected to the top of the annular plate 31, and a mounting plate 33 is fixedly connected to the top of the spring 32. A pneumatic conveying and distributing pipe 34 is fixedly connected to the top of the mounting plate 33. The pneumatic conveying and distributing pipe 34 has a V-shaped longitudinal section and a nozzle 35 is fixedly installed on it. A transmission pipe 36 is fixedly connected to the top of the tower body 1. The transmission pipe 36 passes through the top of the tower body 1. A connecting plate 37 is fixedly connected to the pneumatic conveying and distributing pipe 34, and a vibrating rod 38 is fixedly mounted on the connecting plate 37.

The desulfurizing agent is transmitted into the tower body 1 through the transmission pipe 36 and the pneumatic conveying and distributing pipe 34, and discharged through the spray pipe 35. Under the vibration of the vibrating rod 38, the agent is evenly distributed and fully dispersed. The sulfur-containing gas and the desulfurizing agent fully contact and react inside the tower body 1. The sulfur oxides are absorbed by the desulfurizing agent or converted into harmless substances, thereby achieving the purpose of desulfurization. The purified gas is discharged through the gas outlet pipe 8, while the desulfurization products accumulate at the bottom of the tower body 1.

[0040] like Figure 1 , Figure 3 and Figure 4 As shown, the transmission component 4 includes a sleeve 41 fixed on the frame 2. The sleeve 41 is inclined and has a feed inlet 42 at the top center. The tower body 1 is connected to the sleeve 41 through the feed inlet 42. A shaft 43 is rotatably connected to the sleeve 41. The shaft 43 is coaxial with the sleeve 41 and moves through the left end of the sleeve 41. An auger 44 is fixedly connected to the outer wall of the shaft 43 and is located inside the sleeve 41. A drive motor 45 is fixedly connected to the end of the shaft 43 away from the sleeve 41. A discharge port 46 is opened at the bottom of the sleeve 41 and is located below the right end of the sleeve 41. After the drive motor 45 runs, the shaft 43 drives the auger 44 to rotate, conveying the waste inside the sleeve 41 and discharging it through the discharge port 46.

[0041] like Figure 4 As shown, the bottom of the sleeve 41 is fixedly connected to a drain port 47, and the bottom of the drain port 47 is threadedly connected to a sealing cap 48. The drain port 47 is located below the left end of the sleeve 41. Since the sleeve 41 is inclined, the liquid inside the sleeve 41 is discharged through the drain port 47 and the sealing cap 48.

[0042] like Figure 1 , Figure 3 , Figure 5 ,and Figure 7As shown, the anti-deposition component 5 includes a first movable rod 51 that extends through the bottom of the tower body 1. The first movable rod 51 is inclined. A stirring rod 52 is fixedly connected to the outer wall of the first movable rod 51, and the stirring rod 52 is located at the bottom of the tower body 1. A stabilizing block 53 is fixedly connected to the inner wall of the tower body 1. The stabilizing block 53 is rotatably connected to the first movable rod 51. After the sleeve 41 rotates, it drives the stirring rod 52 to rotate. The stirring rod 52 stirs and treats the waste material deposited at the bottom of the tower body 1, so that the product at the bottom of the tower body 1 can be discharged smoothly.

[0043] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the pretreatment component 6 includes a filter box 61 fixedly mounted on the end of the air inlet pipe 9 away from the tower body 1. A connecting pipe 62 is fixedly connected to the top side of the filter box 61. A filter plate 63 is fixedly connected inside the filter box 61. The outer circumference of the filter plate 63 is equal to the inner circumference of the filter box 61, and the filter plate 63 is inclined. A discharge port 66 is opened at the bottom of the filter box 61. A collection hood 67 is fixedly connected to the filter box 61 through the discharge port 66. A square tube 68 is fixedly connected to the bottom of the collection hood 67. The square tube 68 is rotatably connected to the first movable rod 51, and the first movable rod 51 moves through the square tube 68. The square tube 68 is connected to the sleeve 41. A first valve 69 is fixedly mounted on the square tube 68. The filter plate 63 separates impurities in the sulfur-containing gas. The impurities are then transported to the inside of the sleeve 41 through the combined use of the discharge port 66, the collection hood 67, the square tube 68, and the first valve 69.

[0044] like Figure 5 and Figure 6 As shown, a second movable rod 64 is movably inserted through the side of the filter box 61 away from the air intake pipe 9. The second movable rod 64 is inclined, and the shaft 43, the first movable rod 51 and the second movable rod 64 have the same inclination angle. The second movable rod 64 is rotatably connected to the filter plate 63. A scraper 65 is fixedly connected to the outer wall of the second movable rod 64 near the filter plate 63. The scraper 65 contacts the filter plate 63. After the second movable rod 64 rotates, the scraper 65 rotates accordingly to scrape off the impurities attached to the filter plate 63.

[0045] like Figure 1 , Figure 3 and Figure 5As shown, the transmission assembly 7 is provided in two sets. One set of transmission assembly 7 is located between the anti-deposition assembly 5 and the pretreatment assembly 6, and the other set of transmission assembly 7 is located between the transmission assembly 4 and the anti-deposition assembly 5. The transmission assembly 7 facilitates the transmission of power, so that the shaft 43, the first movable rod 51 and the second movable rod 64 rotate simultaneously. The transmission assembly 7 includes a small transmission wheel 71, a belt 72 and a large transmission wheel 73. The outer circumference of the small transmission wheel 71 is smaller than that of the large transmission wheel 73. The small transmission wheel 71 and the large transmission wheel 73 are connected by the large transmission wheel 73. After the large transmission wheel 73 is rotated under force, the small transmission wheel 71 rotates simultaneously through the action of the belt 72.

[0046] like Figure 1 and Figure 7 As shown, the vibration assembly 11 includes a stabilizing plate 111 and a vibration motor 114. The stabilizing plate 111 is fixedly connected to the tower body 1, and the vibration motor 114 is detachably mounted on the stabilizing plate 111. A buffer pad 112 is tightly attached to the stabilizing plate 111. The buffer pad 112 is mainly made of rubber and has a certain degree of elasticity. A positioning plate 113 is fixedly connected to the upper part of the buffer pad 112. The buffer pad 112 is located between the stabilizing plate 111 and the positioning plate 113. The vibration motor 114 is fixedly connected to the positioning plate 113. Four positioning bolts 115 are threaded onto the stabilizing plate 111 and are evenly distributed. Positioning bolts 115 are threaded through the four corners of the positioning plate 113 and the buffer pad 112, respectively. After the vibration motor 114 is running, the vibration generated is transmitted to the bottom of the tower body 1 through the buffer pad 112, causing the sediment at the bottom of the tower body 1 to loosen continuously under the action of vibration. The stirring rod 52 can more easily contact these loose sediments during rotation, thereby expanding the scraping area. The thickness and hardness of the buffer pad 112 should be reasonably selected according to the power and vibration frequency of the vibration motor 114 to ensure that it can effectively buffer the impact of vibration on the tower body 1 and ensure that the vibration can be smoothly transmitted to the bottom of the tower body 1.

[0047] like Figure 1 and Figure 7 As shown, a reinforcing rib 12 is welded to the outer bottom of the tower body 1, which increases the stability of the connection at the bottom of the tower body 1.

[0048] Working principle:

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, in operation, the sulfur-containing gas is first transported to the interior of the tower body 1 through the pretreatment component 6 and the inlet pipe 9. The filter plate 63 separates impurities such as solid particles, dust, and rust that may be carried by the sulfur-containing gas, ensuring unobstructed internal passages. After the sulfur-containing gas is transported to the interior of the tower body 1, the interior of the tower body 1 is divided into multiple reaction zones by the desulfurization component 3. The desulfurizing agent is transported to the pneumatic conveying and distribution pipe 34 through the transmission pipe 36. The desulfurizing agent in the pneumatic conveying and distribution pipe 34 is sprayed downwards through the nozzle 35, so that the desulfurizing agent is evenly distributed in the tower body 1. At the same time, the vibrator 38 operates, generating high-frequency micro-amplitude vibrations to prevent the desulfurizing agent from clogging and accumulating in the pipe, ensuring smooth transport of the desulfurizing agent. The desulfurization products accumulate at the bottom of the tower body 1, and are transported downwards to the interior of the feed inlet 42 through the second valve 10, driving the motor 45 to rotate. The shaft 43 drives the auger 44 to rotate, transferring the waste inside the sleeve 41, which is then discharged through the discharge port 46. While the shaft 43 rotates, it drives the first movable rod 51 to rotate through the transmission assembly 7. The first movable rod 51 drives the stirring rod 52 to rotate, stirring the waste at the bottom of the tower body 1 to prevent the waste from settling at the bottom of the tower body 1 during discharge. Some of the liquid material inside the sleeve 41 flows to the downward tilted side of the sleeve 41 and is discharged through the drain port 47 and the sealing cover 48. The first movable rod 51 causes the second movable rod 64 to rotate through the transmission assembly 7. The scraper 65 scrapes the filter plate 63 to prevent a large amount of impurities in the sulfur-containing gas from adhering to the filter plate 63. The impurities are discharged downward into the inside of the sleeve 41 through the discharge port 66, the collection hood 67, the square pipe 68 and the first valve 69, and transferred and transferred, thereby transferring and treating the impurities in the sulfur-containing gas and the waste generated from desulfurization.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
