Description

Technical Field

[0001] This utility model relates to the field of desulfurization technology, and in particular to a circulating desulfurization mechanism for desulfurization. Background Technology

[0002] In industries that emit sulfur-containing waste gas, such as coal-fired power plants and chemical plants, desulfurization is an essential step. The main purpose of this process is to remove sulfur dioxide and other sulfur-containing compounds from the flue gas to reduce environmental pollution and harm to human health. The emission of sulfur-containing waste gas not only leads to a decline in air quality but may also trigger acid rain, causing serious impacts on the ecosystem.

[0003] When performing desulfurization, the desulfurization liquid is usually sprayed evenly into the flue gas to effectively remove sulfur dioxide. However, current desulfurization structures usually spray the desulfurization liquid directly. After preliminary treatment, the sprayed desulfurization liquid is often directly discharged without effective recycling, which further increases the cost of desulfurization. To address this, we provide a circulating desulfurization mechanism. Utility Model Content

[0029] The spray structure installed on the desulfurization tower 2 includes a first pump body 303 installed on the outer surface of the liquid storage tank 301.

A set of spray heads 306 are fixedly connected to the outer surface of the annular pipe 305. Each spray head 306 penetrates the desulfurization tower 2 and extends into its interior. When the first pump body 303 is working, the desulfurization liquid inside the liquid storage tank 301 is drawn into the annular pipe 305, and the spray heads 306 spray the desulfurization liquid into the desulfurization tower 2, thereby completing the desulfurization work on the flue gas inside the desulfurization tower 2.

[0030] Second Embodiment

[0031] As attached Figure 1 Appendix Figure 2 Appendix Figure 4 With appendix Figure 5 As shown: the circulation component 4 is set above the base plate 1, including a recycling cylinder 401 set above the base plate 1 and a removable sealing cover 402 set on the top of the recycling cylinder 401. The sealing cover 402 facilitates the addition of regenerating agent to the recycling cylinder 401 by the staff. The regenerating agent can be lime or carbide slag.

[0032] The collection structure of the circulation component 4 is located outside the regeneration cylinder 401. The collection structure includes a second pump body 403 installed on the outer surface of the regeneration cylinder 401. The output end of the second pump body 403 extends to the top of the inside of the regeneration cylinder 401. The input end of the second pump body 403 is fixedly connected to the liquid collection pipe 404. When the second pump body 403 is working, the desulfurization liquid that enters the liquid collection pipe 404 will be drawn into the regeneration cylinder 401, which is beneficial to the subsequent regeneration of the desulfurization liquid.

[0033] The inlet end of the liquid collecting pipe 404 is fixedly connected to a filter screen 405. The filter screen 405 can increase the collection area of ​​the liquid collecting pipe 404, thereby ensuring that all the dripping desulfurization liquid is collected to prevent the desulfurization liquid from spilling. At the same time, it can filter impurities in the desulfurization liquid to prevent impurities from entering the liquid collecting pipe 404 and causing blockage.

[0034] A set of support rods 406 are fixedly connected to the outer surface of the filter screen cover 405. The bottom end of each support rod 406 is connected to the upper surface of the base plate 1. The support rods 406 can be used to support and reinforce the filter screen cover 405, thereby ensuring that the filter screen cover 405 is firm when collecting desulfurization liquid.

[0035] The stirring structure inside the regeneration cylinder 401 includes a motor 407 installed on the bottom wall of the regeneration cylinder 401. A rotating rod 408 is fixedly connected to the output end of the motor 407. A set of stirring plates 409 are fixedly connected to the outer surface of the rotating rod 408. A baffle 410 is rotatably connected to the outer surface of the rotating rod 408. The outer surface of the baffle 410 is connected to the inner wall of the regeneration cylinder 401. The baffle 410 can block the motor 407 from above. When the motor 407 is working, it will drive the rotating rod 408 to rotate. The stirring plates 409 will stir the regenerator and the used desulfurization liquid, which can make the regenerator and desulfurization liquid fully mixed, accelerate the regeneration speed of the desulfurization liquid, and complete the regeneration of the desulfurization liquid.

[0036] A reflux structure is installed outside the regeneration cylinder 401 and connected to the storage cylinder 301. The reflux structure of the circulation component 4 includes a third pump body 411 installed on the outer surface of the regeneration cylinder 401. The input end of the third pump body 411 extends to the lower middle end inside the regeneration cylinder 401 and is connected to a filter cover 412. The output end of the third pump body 411 is fixedly connected to a drain pipe 413. The output end of the drain pipe 413 is connected to the outer surface of the storage cylinder 301. When the third pump body 411 is working, it can draw the desulfurization liquid regenerated inside the regeneration cylinder 401. The filter cover 412 can play a filtering role to prevent the generation of solid waste from being drawn in. The regenerated desulfurization liquid will be drawn into the storage cylinder 301, thereby realizing the recycling of the desulfurization liquid and reducing the desulfurization cost.

[0037] The solid discharge structure of the circulation component 4 is located outside the regeneration cylinder 401. The solid discharge structure includes a slurry pump 414 installed on the outer surface of the regeneration cylinder 401. The input end of the slurry pump 414 extends into the interior of the regeneration cylinder 401. A collection box 415 is provided below the output end of the slurry pump 414. When the regenerated desulfurization liquid is pumped out, the slurry pump 414 is started, and the generated solid waste is pumped into the collection box 415, thereby freeing up the internal space of the regeneration cylinder 401, which is conducive to the continuous regeneration of the desulfurization liquid in the future.

[0038] Working principle: First, the first pump 303 is started, drawing the desulfurization liquid into the annular pipe 305. The spray head 306 then sprays the desulfurization liquid for desulfurization. After use, the desulfurization liquid drips into the filter screen 405. Next, the second pump 403 is started, drawing the desulfurization liquid into the regeneration cylinder 401. Then, a regenerating agent is added into the regeneration cylinder 401 through the sealing cover 402. The motor 407 is started, driving the rotating rod 408 and stirring plate 409 to stir the desulfurization liquid and regenerating agent, converting the sulfur in the desulfurization liquid into a solid form and regenerating the desulfurization liquid. After a period of stillness, the third pump 411 is started, drawing the regenerated desulfurization liquid in the regeneration cylinder 401 into the storage tank 301 for recycling, further reducing desulfurization costs. Finally, the discharge pump 414 is started, drawing the large solid waste generated into the collection box 415.
