Description

Technical Field

[0001] This invention relates to the field of flue gas treatment technology, and in particular to a rapid desulfurization device for a desulfurization tower and its usage method. Background Technology

[0002] Flue gas treatment refers to the purification of flue gas generated during industrial production, energy combustion, and other processes to remove pollutants in order to meet environmental emission standards and reduce harm to the environment and human health. In the flue gas treatment process, desulfurization towers are often used to treat sulfur compounds in the flue gas.

[0003] When using desulfurization towers to treat sulfur compounds in flue gas, traditional desulfurization towers often achieve desulfurization by mixing various chemical agents and reacting them with the flue gas to be treated through spraying or other methods. However, uneven mixing of the agents during the mixing process may result in the desulfurization rate of the flue gas not reaching the expected effect. This requires relevant personnel to re-mix and perform secondary desulfurization, which not only consumes a lot of time but also affects the desulfurization efficiency of the desulfurization tower.

[0041] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] This invention proposes a rapid desulfurization device for a desulfurization tower, as described below. Figures 1 to 7 Please provide a detailed explanation.

[0043] A rapid desulfurization device for a desulfurization tower 1 includes a desulfurization tower 1, a desulfurization mechanism 3 is provided on one side of the desulfurization tower 1, a spray pipe 2 is provided between the desulfurization mechanism 3 and the desulfurization tower 1, and a first water pump 37 is provided on the spray pipe 2.

[0044] The desulfurization mechanism 3 includes a water tank 31, which has a plurality of first mounting holes 32. Each first mounting hole 32 is provided with a stirring assembly. The stirring assembly includes a cover plate 33 covering the first mounting hole 32. A stirring rod 35 is provided through the cover plate 33 facing the inside of the water tank 31. The end of the stirring rod 35 away from the water tank 31 is connected to a first motor 34. Each cover plate 33 is provided with a feeding port 36.

[0045] A wastewater return pipe 381 is provided between the water tank 31 and the desulfurization tower 1, and a wastewater filter assembly 38 is provided at the position where the water tank 31 is connected to the wastewater return pipe 381.

[0046] By setting up the water tank 31, the present invention allows different chemical agents to be added through multiple feeding ports 36 during desulfurization. These chemical agents and liquids such as water can be evenly mixed by the stirring rod 35. At the same time, the liquid produced after desulfurization can be filtered and reused, thereby improving the desulfurization efficiency of the desulfurization tower 1.

[0047] Specifically, multiple first mounting holes 32 are arranged in an array at equal intervals on the top wall of the water tank 31. The array arrangement of multiple first mounting holes 32 ensures that the stirring components in each first mounting hole 32 can be evenly distributed, thereby ensuring uniform stirring of the desulfurization liquid in the water tank 31. The setting of the feeding port 36 allows the staff to easily add one or more suitable high-purity absorbents into the water tank 31 according to the different components of the desulfurization flue gas. An appropriate amount of activator can also be added through the feeding port 36. Then, by starting the first motor 34 in each stirring component, the first motor 34 drives the stirring shaft to rotate, thereby completing the stirring of the liquid inside the water tank 31.

[0048] After stirring, the desulfurization liquid in the water tank 31 is pumped into the desulfurization tower 1 through the spray pipe 2 by the first water pump 37. The liquid is atomized and sprayed in the desulfurization tower 1 to react with the flue gas in the desulfurization tower 1 and remove sulfides from the flue gas.

[0049] The solid or liquid products generated by the reaction are returned to the wastewater filter assembly 38 in the water tank 31 through the wastewater return pipe 381. After being treated by the wastewater filter assembly 38, the liquid can be returned to the water tank 31 for recycling.

[0050] In some embodiments, the stirring rod 35 is provided with multiple stirring blades. The arrangement of the stirring blades can make the stirring effect more uniform.

[0051] In some embodiments, the wastewater filtration assembly 38 is disposed below the wastewater return pipe 381, and the water tank 31 is provided with an installation frame 382, ​​in which a filter box 383 is detachably fitted.

[0052] The filter box 383 is opened towards the wastewater return pipe 381, and the filter box 383 is provided with multiple water passages away from the wastewater return pipe 381.

[0053] The filter box 383 is detachably provided with an isolation net 387. Specifically, in one embodiment, the isolation net 387 can be fixedly connected to the inner wall of the filter box 383 by bolts. In another embodiment, the inner wall of the filter box 383 is provided with a support boss for supporting the isolation net 387.

[0054] The solid or liquid products generated by the desulfurization reaction in the desulfurization tower 1 are returned to the wastewater filter assembly 38 in the water tank 31 through the wastewater return pipe 381. The isolation net 387 can filter out the solid products with larger particle size to prevent the larger solid products from clogging the water passage.

[0055] In some embodiments, the filter box 383 is equipped with an activated carbon element 385, and the wastewater in the filter box 383 can flow out through the water passage through the activated carbon element 385. The activated carbon can adsorb sulfides in the wastewater, so that the wastewater can re-enter the water tank 31 for use in the next desulfurization process.

[0056] In some embodiments, a replacement slot 384 is provided on the side wall of the filter box 383 at the position corresponding to the activated carbon component 385. The replacement slot 384 is connected to the bottom wall of the filter box 383. A rotating flip cover 386 is hinged inside the replacement slot 384, and a fixing structure 4 is provided between the rotating flip cover 386 and the replacement slot 384. The replacement slot 384 provides space for removing and installing the activated carbon component 385, and the rotating flip cover 386 and the fixing structure 4 can fix the activated carbon component 385 under normal conditions, preventing the activated carbon component 385 from detaching from the replacement slot 384.

[0057] In some embodiments, the fixing structure 4 includes a fixing groove opened on the side wall of the replacement groove 384, the rotating flip cover 386 is integrally provided with a fixing block in conjunction with the fixing groove, the bottom wall of the filter box 383 is provided with a second mounting hole 41 through the fixing groove, and the fixing block is provided with a limiting hole 45 in conjunction with the second mounting hole 41.

[0058] A retainer 42 is provided through the second mounting hole 41. The retainer 42 has a limiting head at one end facing the filter box 383. The second mounting hole 41 includes a first hole segment and a second hole segment arranged sequentially in the direction away from the filter box 383. The inner diameter of the first hole segment is larger than the inner diameter of the second hole segment, and the inner diameter of the second hole segment is not smaller than the outer diameter of the retainer 42.

[0059] A spring 44 is sleeved on the outside of the bolt 42 inside the first hole section. A limiting head is provided at one end of the bolt 42 facing the fixing groove. One end of the spring 44 is fixedly connected to the limiting head, and the other end of the spring 44 is fixedly connected to the end face of the second hole section.

[0060] The end of the latch 42 facing away from the filter box 383 is provided with a limiting block 43 to prevent the latch 42 from dislodging from the second mounting hole 41. The limiting block is provided with a pull ring 46, which can be used by the operator to control the movement of the latch 42.

[0061] Under normal operating conditions, the limiting head of the latch 42 passes through the second mounting hole 41 and the limiting hole 45, thereby restricting the movement of the rotating flip cover 386 and keeping the rotating flip cover 386 parallel and coplanar with the outer wall of the filter box 383. When the activated carbon component 385 needs to be replaced, the operator pulls the pull ring 46 at the bottom of the filter box 383 to move the latch 42 down and disengage it from the limiting hole 45, thereby releasing the restriction of the degree of freedom of the rotating flip cover 386 by the latch 42. The operator can then control the rotation of the rotating flip cover 386 to remove the activated carbon component 385.

[0062] In some embodiments, the spray pipe 2 is provided with a cleaning assembly for cleaning the inside of the spray pipe 2. The cleaning assembly includes a bracket 5l disposed at the end of the spray pipe 2 away from the water tank 31. A second motor 54 is disposed on the bracket 5l. A threaded rod 53 is fixedly connected to the output end of the second motor 54 facing the inside of the spray pipe 2. A scraper 52 is externally threaded to the threaded rod 53. The outer diameter of the scraper 52 is not greater than the inner diameter of the spray pipe 2. A guide groove is provided inside the spray pipe 2 for guiding the movement of the scraper 52. A guide block is provided on the scraper 52 and slidably connected to the guide groove. A scale discharge pipe 55 is connected to the end of the spray pipe 2 away from the water tank 31.

[0063] Specifically, during long-term use, scale easily accumulates on the inner wall of the spray pipe. By controlling the forward and reverse rotation of the second motor 54, the threaded rod 53 is driven to rotate accordingly. The threaded rod 53 drives the scraper 52 to move up and down along the spray pipe 2, which can clean the dirt on the inner wall of the spray pipe 2.

[0064] Furthermore, in some embodiments, to avoid the scraper 52 obstructing the normal water supply of the spray pipe 2, the spray pipe 2 is divided into a first pipe and a second pipe that are interconnected. The first pipe is connected to the outlet of the first water pump 37, and the second pipe is connected to the desulfurization tower 1. The end of the second pipe facing the water tank 31 has a storage space reserved for the scraper 52 in the non-cleaning state. The connection position between the first pipe and the second pipe is located above the storage space, thereby avoiding the scraper 52 obstructing the normal liquid supply of the spray pipe 2.

[0065] In some embodiments, since the scale on the inner wall of the spray pipe 2 may be too hard, causing the scraper 52 to malfunction or be damaged during operation, the spray pipe 2 is provided with a descaling agent supply component at the end facing the water tank 31 to provide descaling agent to the cleaning component.

[0066] The drug supply assembly includes a drug storage tank 58 disposed above the water tank 31. The drug storage tank 58 is connected to the end of the spray pipe 2 facing the water tank 31 by a connecting pipe 59. A second water pump 510 is provided on the connecting pipe 59.

[0067] The spray pipe 2 is provided with a water inlet pipe 56 that is connected to the backtracking connection pipe 59. The threaded rod 53 is provided with a water passage and multiple water outlets connected to the water passage are provided on the threaded rod 53. The water inlet pipe 56 is connected to the threaded rod 53 and the water inlet pipe 56 and the threaded rod 53 are connected by a sealed rotary joint.

[0068] Dilute acid is added to the storage tank 58, and then the second water pump 510 is started to transport the dilute acid to the inlet pipe 56 through the connecting pipe 59. Then, the acid comes into contact with the scale on the inner wall of the spray pipe through the outlet hole 57 on the outer wall of the threaded rod 53 and reacts. After a certain reaction time, the second motor 54 is started, which drives the threaded rod 53 to rotate. At this time, the scraper 52, which is threaded to the threaded rod 53, is driven to move towards the scale discharge pipe 55. During the movement, the scraper 52 scrapes off the scale on the inner wall of the spray pipe and pushes it into the scale discharge pipe 55 for treatment, thereby preventing the spray pipe from being blocked during use.

[0069] This invention also provides a method for using a rapid desulfurization device in a desulfurization tower, as described below. Figure 8 Please provide a detailed explanation.

[0070] A method for using a rapid desulfurization device in a desulfurization tower includes the following steps:

[0071] S1. Depending on the specific conditions of the flue gas to be desulfurized, various high-purity absorbents and an appropriate amount of activator are added to the water tank 31 through the feeding port 36 and mixed evenly by the stirring rod 35 to obtain the first liquid.

[0072] S2. The first liquid after mixing is pumped into the desulfurization tower 1 through the first water pump 37 along the spray pipe 2, and atomized spraying is achieved in the desulfurization tower 1, so that the first liquid and the flue gas in the desulfurization tower 1 are in uniform contact and reaction, so that the sulfur compounds in the flue gas are converted into undetermined solids or liquids. The converted solids and liquids are discharged into the water tank 31 through the wastewater return pipe 381.

[0073] S3. The wastewater and liquid flowing out from the wastewater return pipe 381 will be processed by the wastewater filter component 38. The wastewater filter component 38 will filter the solids and adsorb the sulfur compounds in the liquid, thus completing the treatment of the wastewater.

[0074] In some embodiments, when the spray pipe 2 needs to be cleaned, the second water pump 510 is controlled to pump the medicine in the medicine storage tank 58 into the threaded rod 53, and the medicine enters the spray pipe 2 through the water outlet 57; the second motor 54 is controlled to rotate forward or backward, thereby driving the scraper 52 to move up and down in the spray pipe 2 to scrape and clean the dirt on the inner wall of the spray pipe 2.

9. A method of using the rapid desulfurization device of the desulfurization tower as described in claim 8, characterized in that, Includes the following steps: S1. Depending on the specific conditions of the flue gas to be desulfurized, various high-purity absorbents and appropriate amounts of activators are added to the water tank through the feeding port and mixed evenly with a stirring rod to obtain the first liquid. S2. The first liquid after mixing is pumped into the desulfurization tower through the first water pump along the spray pipe, and atomized spraying is achieved in the desulfurization tower so that the first liquid comes into uniform contact with the flue gas in the desulfurization tower and reacts, so that the sulfur compounds in the flue gas are converted into undetermined solids or liquids. The converted solids and liquids are discharged into the water tank through the wastewater return pipe. S3. Wastewater and liquid flowing out from the wastewater return pipe will be treated by the wastewater filtration component. The wastewater filtration component will filter the solids and adsorb the sulfur compounds in the liquid, thus completing the wastewater treatment.
