Description

Technical Field

[0001] This utility model relates to the field of cyclone spraying technology, specifically to a cyclone spraying device for a wet desulfurization tower. Background Technology

[0002] In the chemical industry, the emission of sulfur-containing flue gas is one of the important factors causing air pollution, posing a serious threat to the ecological environment and human health. In order to achieve sustainable development and meet environmental protection requirements, desulfurization of sulfur-containing flue gas has become an indispensable part of the chemical production process. Among them, wet desulfurization technology has been widely used in chemical equipment and plants due to its advantages such as high desulfurization efficiency and mature process.

[0003] However, traditional wet desulfurization towers cannot effectively slow down the rising speed of flue gas or evenly disperse it when treating sulfur-containing flue gas. This causes the flue gas to move upward rapidly after entering the desulfurization tower, resulting in a short residence time inside the tower. Consequently, some flue gas leaves the desulfurization tower without fully contacting and reacting with the desulfurizing agent sprayed by the spray system. This not only reduces the desulfurization effect but may also make it difficult for the emitted flue gas to meet environmental standards, affecting the stability and reliability of the overall desulfurization process. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a wet desulfurization tower swirl spray device, which has the advantages of slowing down the rising speed of flue gas, uniformly increasing the flue gas diffusion area, and improving the contact reaction effect between flue gas and desulfurizing agent. This solves the problem that traditional desulfurization towers lack the function of slowing down the flow and spreading of flue gas, resulting in the flue gas rising rapidly and leaving before fully reacting.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a wet desulfurization tower swirl spray device, comprising a desulfurization tower body, an inlet pipe fixedly installed on the outer side of the desulfurization tower body near the bottom, a filter plate fixedly installed inside the desulfurization tower body near the exhaust port, and a flue gas slow-flow diffusion component for slowing down the rising velocity of flue gas and uniformly increasing the diffusion area is provided inside the desulfurization tower body and above the inlet pipe. The swirl spray component is installed by a three-bar support set on the inner wall of the desulfurization tower body, wherein the swirl spray component is located between the flue gas slow-flow diffusion component and the filter plate. The flue gas slow-flow diffusion component consists of a flow-blocking column and a flow-dividing pipe, and a flow-dividing component is provided inside the flow-dividing pipe, through which the flue gas is discharged.

[0006] As a preferred technical solution of this utility model, the flow-blocking column is fixedly installed inside the desulfurization tower body, and the bottom of the flow-blocking column is provided with several conical flue gas inlet holes.

[0007] As a preferred technical solution of this utility model, the diversion pipe is fixedly installed inside the smoke inlet hole with one end protruding, and several spiral blades are fixedly installed inside the diversion pipe.

[0008] As a preferred embodiment of this utility model, a horn-shaped diffuser is fixedly installed on the top of the diverter, and the top of the horn-shaped diffuser has several diffusion holes.

[0009] As a preferred embodiment of this utility model, the three-bar support is connected by a mounting ring, and the vortex spray assembly includes a liquid storage pipe, which is fixedly installed on the inner side of the mounting ring.

[0010] As a preferred embodiment of this utility model, an infusion pipe is movably installed at the bottom of the liquid storage pipe, and four spray pipes are symmetrically fixedly installed on the outside of the infusion pipe, and several sets of inclined nozzles are fixedly installed on the outside of the spray pipes.

[0011] As a preferred technical solution of this utility model, the nozzles are distributed in a straight line at equal intervals along the outer side of the spray conduit, wherein four sets of spray conduits are arranged on the outer side of the infusion pipe, and the nozzles on every two sets of spray conduits are arranged at a 90-degree angle.

[0012] As a preferred embodiment of this utility model, the nozzle is inclined, the smoke inlet is conical, and the diffuser holes are arranged in a hexagonal honeycomb array.

[0013] The beneficial effects of this utility model are as follows: This invention incorporates a flue gas slow-flow diffusion component, which combines a flow-blocking column, a flue gas inlet, a diversion pipe, and spiral blades. This allows the flue gas to swirl after entering the diversion pipe due to the action of the spiral blades, extending the upward path and slowing down the speed. The funnel-shaped diffuser and hexagonal honeycomb diffuser holes further guide and disperse the flue gas, significantly increasing the diffusion area and making the flue gas distribution more uniform. This enhances the contact effect with the spray liquid and strengthens the desulfurization reaction.

[0014] With the help of the swirl spray assembly, the bracket and mounting ring provide stable support for the liquid storage pipe. The L-shaped liquid inlet pipe facilitates the introduction of desulfurization liquid. The rotating liquid delivery pipe, together with the inclined nozzle, makes the spray range more comprehensive, allowing the desulfurization liquid to fully contact and react with the slowly spreading flue gas, efficiently removing pollutants from the flue gas and ensuring the desulfurization effect and operational stability of the wet desulfurization tower.

However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0018] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 -Appendix Figure 6 The present invention will be further described below.

[0019] A wet desulfurization tower swirl spray device includes a desulfurization tower body 1. An inlet pipe 2 is fixedly installed on the outside of the desulfurization tower body 1 near the bottom. A filter plate 3 is fixedly installed inside the desulfurization tower body 1 near the exhaust port. A flue gas slow flow diffusion component is installed inside the desulfurization tower body 1 and above the inlet pipe 2 to slow down the rising velocity of the flue gas and uniformly increase the diffusion area. The swirl spray component is installed by a three-bar bracket 4 set on the inner wall of the desulfurization tower body 1. The swirl spray component is located between the flue gas slow flow diffusion component and the filter plate 3. The flue gas slow flow diffusion component consists of a flow-blocking column 11 and a diversion pipe 13. A slow flow component is installed inside the diversion pipe 13, and the flue gas is discharged through the slow flow component.

[0020] In this implementation scheme, the desulfurization tower body 1 serves as the basic carrier of the entire device, providing installation space for the flue gas inlet pipe 2, filter plate 3, flue gas slow-flow diffusion component, and swirl spray component. It is the core location for the flue gas desulfurization reaction. The flue gas inlet pipe 2 is used to introduce the sulfur-containing flue gas to be desulfurized into the interior of the desulfurization tower body 1, providing a treatment medium for the subsequent desulfurization reaction. The filter plate 3 uses polyphenylene sulfide membrane filter material and is located above the swirl spray component to intercept and capture the fine particulate matter remaining in the flue gas after the desulfurization reaction. The flue gas slow-flow diffusion component can slow down the rising speed of the flue gas, uniformly increase the flue gas diffusion area, make the flue gas distribution more uniform, and improve the contact effect with the spray liquid, creating conditions for efficient desulfurization. The swirl spray component is used to spray the desulfurization liquid in the form of swirl spray, which fully contacts and reacts with the flue gas after slow-flow diffusion, thereby removing pollutants from the flue gas.

[0021] Specifically, the flue gas slow flow diffusion component includes a flow-blocking column 11, which is fixedly installed inside the desulfurization tower body 1, and the bottom of the flow-blocking column 11 is provided with several flue gas inlet holes 12. It also includes several diversion pipes 13, which are fixedly installed inside the smoke inlet 12, and several spiral blades 14 are fixedly installed inside the diversion pipes 13. It also includes a horn-shaped diffuser tube 15, which is fixedly installed on the top of the diverter tube 13, and the top of the horn-shaped diffuser tube 15 is provided with a number of diffusion holes 16.

[0022] In this embodiment, a flow-blocking column 11 is installed inside the desulfurization tower body 1 to provide a stable installation foundation for the flue gas inlet 12 and the diversion pipe 13. The flue gas inlet 12 is located at the bottom of the flow-blocking column 11, serving as a channel for flue gas to enter the diversion pipe 13, and is tapered to facilitate the smooth introduction of flue gas into the diversion pipe 13. The diversion pipe 13 is fixed inside the flue gas inlet 12, providing a path for flue gas flow and providing an installation carrier for the spiral blades 14 and the trumpet-shaped diffuser 15, guiding the flue gas to flow spirally upward. The spiral blades 14 are installed inside the diversion pipe 13, allowing the flue gas to enter the diversion pipe. The flue gas in pipe 13 generates a swirling flow, extending the upward path of the flue gas and thus slowing down the upward speed of the flue gas, providing more reaction time for the already discharged flue gas. The trumpet-shaped diffuser 15 is fixed to the top of the diversion pipe 13, which guides the flue gas passing through the diversion pipe 13, helps the flue gas to diffuse in all directions, and expands the initial diffusion range. The diffusion holes 16 are opened on the top of the trumpet-shaped diffuser 15 and are distributed in a hexagonal honeycomb array, further dispersing the flue gas, greatly increasing the flue gas diffusion area, making the flue gas distribution more uniform, improving the contact effect with the spray liquid, and ensuring a more complete reaction.

[0023] Specifically, the three-bar support 4 is connected by the mounting ring 5, and the swirl spray assembly includes a liquid storage pipe 6, which is fixedly installed on the inner side of the mounting ring 5; An L-shaped inlet pipe 7 is fixedly installed on the top of the storage pipe 6. The other end of the L-shaped inlet pipe 7 passes through the desulfurization tower body 1 and is connected to an external water pipe. An infusion pipe 8 is movably installed at the bottom of the storage pipe 6. Four spray pipes 9 are symmetrically fixedly installed on the outside of the infusion pipe 8. Several sets of inclined nozzles 10 are fixedly installed on the outside of the spray pipes 9. The nozzles 10 are distributed in a straight line at equal intervals along the outside of the spray conduit 9. There are four sets of spray conduits 9 on the outside of the infusion pipe 8, and the nozzles 10 on each pair of spray conduits 9 are set at a 90-degree angle.

[0024] In this implementation scheme, a three-bar support 4 is set inside the desulfurization tower body 1 to provide stable support for the mounting ring 5, ensuring the overall structural stability of the cyclone spray assembly. The storage pipe 6 is used to store desulfurization liquid and provide a liquid source for the subsequent delivery pipe 8 and nozzle 10. One end of the L-shaped inlet pipe 7 is connected to the storage pipe 6, and the other end passes through the desulfurization tower body 1. It is used to introduce external desulfurization liquid into the storage pipe 6 to achieve a continuous supply of desulfurization liquid. The liquid transported through the L-shaped inlet pipe 7 has a certain hydraulic pressure. Since the delivery pipe 8 is rotatably installed at the bottom of the storage pipe 6, when the liquid is sprayed from the nozzle 10, the liquid spraying generates a reverse force, thereby driving the spray guide pipe 9 and the nozzle 10 to rotate, expanding the spray range, and generating a spiral liquid curtain, so that the sprayed desulfurization liquid can fully contact and react with the rising flue gas, improving the desulfurization effect.

[0025] It should be noted that the nozzle 10 is set at an angle, the smoke inlet 12 is set in a conical shape, and the several diffuser holes 16 are distributed in a hexagonal honeycomb array.

[0026] By setting the conical flue gas inlet 12, the flue gas can enter the diversion pipe 13 more smoothly, which plays a good role in gathering and guiding the flue gas. The diffuser holes 16 are distributed in a hexagonal honeycomb array, which can further disperse the flue gas passing through the trumpet-shaped diffuser 15, greatly increase the flue gas diffusion area, make the flue gas distribution more uniform, effectively improve the contact effect with the spray liquid, and promote the efficient desulfurization reaction.

[0027] In summary: When this utility model is in use, the sulfur-containing flue gas to be treated enters the desulfurization tower body 1 through the flue gas inlet pipe 2, first entering the flue gas slow-flow diffusion component. The flue gas then enters the diversion pipe 13 through the conical flue gas inlet hole 12 at the bottom of the flow-blocking column 11. The spiral blades 14 inside the diversion pipe 13 extend the upward path and slow down the upward speed. Next, the flue gas enters the trumpet-shaped diffuser 15 fixed at the top of the diversion pipe 13, where it initially diffuses to the surroundings under the guiding effect. Finally, it is further dispersed through the hexagonal honeycomb array of diffusion holes 16 at the top of the trumpet-shaped diffuser 15, greatly increasing the diffusion area and making the flue gas distribution more uniform. At the same time, the external desulfurization liquid enters the storage pipe 6 through the L-shaped liquid inlet pipe 7. Fixed within the mounting ring 5 supported by three brackets 4, the desulfurization liquid flows from the storage pipe 6 into the delivery pipe 8, which is rotated and installed at its bottom. It is then transported through four spray pipes 9 on the outside of the delivery pipe 8 to several inclined nozzles 10. When the nozzles 10 spray the desulfurization liquid, they generate a reverse force, which pushes the spray pipes 9 and the delivery pipe 8 to rotate, causing the desulfurization liquid to form a swirling flow. This flow fully contacts and reacts with the flue gas that has passed through the flue gas slow-flow diffusion component, removing pollutants from the flue gas. After the desulfurization reaction is completed, the flue gas continues to rise and passes through the filter plate 3 located above the swirling spray component. The filter plate 3 uses polyphenylene sulfide membrane filter material to intercept and capture the fine particulate matter remaining in the flue gas. Finally, the treated flue gas leaves the desulfurization tower body 1.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
