Description

Technical Field

[0001] This utility model relates to the field of desulfurization tower technology, and in particular to a spray dust removal desulfurization tower. Background Technology

[0002] Desulfurization, broadly speaking, refers to the process of removing sulfur from fuel before combustion and desulfurizing flue gas before emissions. It is one of the important technical measures for preventing and controlling air pollution. Desulfurization methods generally include pre-combustion, during-combustion, and post-combustion desulfurization. With industrial development and the improvement of people's living standards, the demand for energy is constantly increasing, and sulfur dioxide in coal-fired flue gas has become a major cause of air pollution. Reducing sulfur dioxide pollution has become an urgent priority in current air pollution control. Desulfurization is generally carried out in a desulfurization tower, and dust removal spraying is required inside the tower during desulfurization.

[0003] Traditional spray-type dust removal and desulfurization towers typically employ a single spray structure, delivering the treatment liquid to the nozzles via simple pipes for spraying. This structure has several drawbacks: First, the single spray method limits the contact area between the treatment liquid and the exhaust gas, resulting in unsatisfactory dust removal and desulfurization effects, making it difficult to meet increasingly stringent environmental emission standards; second, the spray distribution is uneven, with some areas of exhaust gas not being fully treated, affecting the overall treatment efficiency.

[0004] Therefore, it is necessary to provide a spray dust removal and desulfurization tower to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a spray dust removal and desulfurization tower, which solves the problems in the background art.

[0006] To address the aforementioned technical problems, this utility model provides a spray-type dust removal and desulfurization tower, comprising a tower body. Inside the tower body, a disc-shaped diverter pipe is securely fixed via a connecting rod. A serpentine diverter pipe is installed below the disc-shaped diverter pipe, and the two are connected by a connecting pipe, thus forming a path for the treatment liquid to flow within the tower. A first nozzle is installed on the bottom surface of the disc-shaped diverter pipe, and a second nozzle is installed on the circumferential side of the serpentine diverter pipe. These nozzles are key components for the treatment liquid to be sprayed out and come into contact with the exhaust gas. A pump body is installed on the outer surface of the tower body. The output end of the pump body is connected to the disc-shaped diverter pipe via a pipe, and the input end is also connected to the treatment liquid via a pipe. Through this connection, the pump body can draw and transport the treatment liquid to the disc-shaped diverter pipe, providing power for the spraying of the treatment liquid. The combination of the disc-shaped and serpentine diverter pipes, along with the nozzles at different positions, allows the treatment liquid to be sprayed from different directions and positions, ensuring full contact with the exhaust gas, thereby achieving dust removal and desulfurization treatment.

[0007] Preferably, two sets of the disc-shaped and serpentine diversion pipes are installed, and they are alternately connected vertically. This alternating installation method further optimizes the spray distribution of the treatment liquid in the desulfurization tower, allowing the treatment liquid to cover the waste gas flow area more comprehensively and evenly, avoiding situations where some areas of waste gas cannot be fully treated, and comprehensively improving the effect and efficiency of dust removal and desulfurization.

[0008] Preferably, multiple first nozzles are installed, and these first nozzles are equidistantly mounted on the bottom surface of the disc-shaped diverter. This arrangement allows the treatment liquid to be sprayed downwards evenly, making initial contact with the rising exhaust gas and performing preliminary dust removal and desulfurization treatment on the exhaust gas. Multiple second nozzles are installed, and these second nozzles are equidistantly mounted around the periphery of the serpentine diverter, allowing the treatment liquid to be sprayed from multiple angles on the side, enhancing the lateral contact with the exhaust gas. This, in conjunction with the first nozzles, further improves the contact area between the treatment liquid and the exhaust gas and the treatment effect.

[0009] Preferably, an exhaust pipe is installed above the surface of the desulfurization tower body to discharge the clean gas after dust removal and desulfurization treatment outside the tower; an inlet pipe is installed below the surface of the desulfurization tower body to introduce the waste gas to be treated. The reasonable position design of the inlet and exhaust pipes ensures that the waste gas can flow in the tower according to the predetermined path and successfully complete the dust removal and desulfurization treatment process.

[0010] Preferably, a top cover is installed on the top surface of the desulfurization tower body to seal the top of the desulfurization tower and prevent waste gas leakage and debris from entering the tower. A drain pipe is installed below the surface of the desulfurization tower body, and a valve is installed on the drain pipe. The treatment liquid that has absorbed pollutants and dust flows downward under the action of gravity and is discharged outside the tower through the drain pipe. The valve can control the time and flow rate of the drain, which facilitates subsequent treatment and replacement of the treatment liquid.

[0011] Preferably, the desulfurization tower body is equipped with multiple support legs at the bottom end, and the multiple support legs are evenly distributed on the bottom surface of the device body. This layout design of the support legs provides stable support for the entire desulfurization tower, ensuring that the desulfurization tower remains stable during operation and is not shaken by external forces.

[0012] Preferably, a controller is installed on the outer surface of the desulfurization tower body. The controller is connected to equipment such as pumps. The controller can control the operation of equipment such as pumps, such as starting, stopping and adjusting the flow rate of pumps, so as to ensure that the components of the desulfurization tower can work together and complete the dust removal and desulfurization tasks in an orderly manner.

[0013] Compared with related technologies, the spray dust removal and desulfurization tower provided by this utility model has the following beneficial effects:

[0014] Compared to existing technologies, the desulfurization tower features a unique internal design with fixed disc-shaped and serpentine diversion pipes, each equipped with a first and second nozzle. This structure allows the treatment liquid to be sprayed from different directions and positions, significantly increasing the contact area between the treatment liquid and the exhaust gas compared to traditional single-spray structures. This thorough contact between the treatment liquid and the exhaust gas more effectively removes sulfur and dust, significantly improving dust removal and desulfurization efficiency and meeting stringent environmental emission standards. Two sets of disc-shaped and serpentine diversion pipes are installed and alternately connected vertically. This alternating layout of the two sets of diversion pipes achieves comprehensive, multi-layered spray distribution of the treatment liquid within the desulfurization tower. This avoids the problem of insufficient treatment of exhaust gas in some areas, as seen in traditional spraying methods, ensuring that the exhaust gas fully contacts the treatment liquid in all areas of the tower, further improving overall treatment efficiency and quality.

[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figure 1-5A spray dust removal and desulfurization tower is disclosed. The tower body 1 serves as the basic frame, and a disc-shaped diversion pipe 9 is securely installed at a suitable height via high-strength, corrosion-resistant connecting rods, using welding or bolting. Below the disc-shaped diversion pipe 9, a serpentine diversion pipe 10 is fixed with a specially designed U-shaped bracket and bolts. The two are connected by a connecting pipe with welded or flanged ends, forming a treatment liquid transmission channel. Holes are drilled at precise intervals on the bottom surface of the disc-shaped diversion pipe 9, and multiple first nozzles 11 are securely screwed in using threaded connections and sealing gaskets. Interfaces are opened at equal angles on the circumference of the serpentine diversion pipe 10, and multiple second nozzles 12 are also installed using threaded connections to ensure a leak-proof seal.

[0025] Outside the desulfurization tower body 1, the pump body 2 is fixed to the concrete base with anchor bolts. Its output end is connected to the disc-shaped diversion pipe 9 via a pressure-resistant pipe and a flange, while its input end is connected to the treatment liquid storage device. During operation, the pump body 2 draws and pressurizes the treatment liquid and delivers it to the disc-shaped diversion pipe 9. The liquid is sprayed downward through the first nozzle 11 and simultaneously flows into the serpentine diversion pipe 10 through the connecting pipe, where it is sprayed horizontally by the second nozzle 12. This multi-angle spraying ensures that the treatment liquid fully contacts the exhaust gas from bottom to top, significantly improving the dust removal and desulfurization efficiency and solving the problems of small contact area and poor effect of traditional single spraying.

[0026] Example 2

[0027] Please refer to the following: Figure 1-5 Two sets of disc-shaped diversion pipes 9 and serpentine diversion pipes 10 are alternately connected by transition connecting pipes, either by welding or flange connection. The bottom port of the upper disc-shaped diversion pipe 9 is connected to the top port of the lower serpentine diversion pipe 10, and the lower disc-shaped diversion pipe 9 is then connected to the upper serpentine diversion pipe 10, forming a staggered spray layout. This design allows the treated liquid to be sprayed three-dimensionally within the tower, covering the entire flow area of ​​the exhaust gas and avoiding treatment blind spots. Compared with a single-set structure, the treatment efficiency and uniformity are significantly improved, better meeting environmental standards.

[0028] Example 3

[0029] Please refer to the following: Figure 1-5 During the manufacturing of the disc-shaped diverter pipe 9, the first nozzle 11 has pre-drilled mounting holes according to the calculated circumferential spacing. During installation, a high-precision threaded fit is used to ensure consistent torque, allowing the treatment liquid to be sprayed evenly and vertically downwards, initially contacting and reacting with the rising exhaust gas. The second nozzle 12 is installed at an equal angle during the machining of the serpentine diverter pipe 10. It is connected by threads and fitted with a seal, spraying the treatment liquid from multiple angles on the side. This liquid flow complements the liquid flow from the first nozzle 11, forming a three-dimensional, interwoven spray net, further expanding the gas-liquid contact area and enhancing the dust removal and desulfurization effect.

[0030] Example 4

[0031] Please refer to the following: Figure 1-5 Above the surface of the desulfurization tower body 1, the exhaust pipe 4 is installed through by welding, and internally, baffles or demisters are fixed with bolts to separate mist droplets from the purified gas. The lower inlet pipe 8 is also welded through, with an airflow distribution plate installed at the inlet with bolts. The waste gas to be treated introduced through the inlet pipe 8 is homogenized by the distribution plate and flows upward along the tower body, fully contacting and reacting with the treatment liquid. The treated clean gas is discharged through the exhaust pipe 4. The reasonable pipeline layout ensures a smooth and efficient waste gas treatment process.

[0032] Example 5

[0033] Please refer to the following: Figure 1-5 The top of the desulfurization tower body 1 is connected to the top cover 3 by a flange and a sealing gasket to achieve top sealing, preventing exhaust gas leakage and debris entry. The lower drain pipe 6 is welded through and connected to the valve by threads or flanges. The treated liquid that absorbs pollutants collects at the bottom of the tower under gravity and is discharged through the drain pipe 6. The valve can flexibly control the discharge time and flow rate, facilitating the replacement of the treated liquid and subsequent treatment, and maintaining a stable treatment environment inside the tower.

[0034] Example 6

[0035] Please refer to the following: Figure 1-5 At the bottom of the desulfurization tower body 1, multiple support legs 7 are made of high-strength steel and are fixed to the tower body by welding or bolts. The bottom pad is connected to the concrete foundation by anchor bolts, and the support legs 7 are evenly distributed. This structure provides stable support for the desulfurization tower, evenly bears the weight of the equipment and the pressure of the internal medium, resists external wind, vibration and other interference, ensures stable operation of the equipment, and extends its service life.

[0036] Example 7

[0037] Please refer to the following: Figure 1-5 On the outside of the desulfurization tower body 1, the controller 5 is fixed to an easily accessible position with bolts via a bracket and is connected to the pump body 2, valves, and other equipment via cables. During operation, the controller 5 monitors equipment parameters in real time, such as the flow rate of the treated liquid and the pressure inside the tower. According to the preset program, it automatically controls the start and stop of the pump body 2, adjusts the flow rate, and coordinates the work of various components to ensure that the dust removal and desulfurization tasks are completed efficiently and in an orderly manner, realizing intelligent operation and management of the equipment.

[0038] It should be noted that the control circuit of controller 5 can be implemented by those skilled in the art through simple programming, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0039] The working principle of the spray dust removal and desulfurization tower provided by this utility model is as follows:

[0040] When desulfurization and dust removal operations are required, the waste gas to be treated enters the desulfurization tower body 1 through the inlet pipe 8. At this time, the pump 2 is started under the control of the controller 5, drawing the treatment liquid from the storage area through the pipeline to the disc-shaped diversion pipe 9. The disc-shaped diversion pipe 9 has a disc-shaped structure, and multiple first nozzles 11 installed at equal intervals on its bottom surface will spray the treatment liquid downwards, forming a top-down spraying effect, initially contacting the rising waste gas, and adsorbing and neutralizing some of the dust and sulfur in the waste gas.

[0041] Simultaneously, the treatment fluid in the disc-shaped diverter 9 flows into the serpentine diverter 10 through the connecting pipe. The unique curved shape of the serpentine diverter 10 allows multiple second nozzles 12, evenly spaced around its perimeter, to spray the treatment fluid from multiple angles on the side, ensuring more thorough lateral contact with the exhaust gas. The two sets of disc-shaped diverter 9 and serpentine diverter 10 are alternately connected vertically, further enhancing the coverage and uniformity of the treatment fluid spray.

[0042] During the process of full contact between the treatment liquid and the waste gas, the effective components in the treatment liquid react chemically with pollutants such as sulfur dioxide in the waste gas, converting them into water-soluble substances; at the same time, the treatment liquid adsorbs particulate matter such as dust in the waste gas, causing it to settle. The treated gas is relatively clean and is discharged through the exhaust pipe 4 installed above the surface of the desulfurization tower body 1.

[0043] The treated liquid, having absorbed pollutants and dust, flows downwards under gravity and is eventually discharged through the drain pipe 6 installed below the surface of the desulfurization tower body 1. Valves installed on the drain pipe 6 control the timing and flow rate of the discharge, facilitating subsequent treatment and replacement of the treated liquid and ensuring the continuous and stable operation of the desulfurization tower.

[0044] It should be noted that all components used in this application are standard parts that can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets and welding that are mature in the prior art. The mechanical parts and electrical equipment adopt conventional models in the prior art. The circuit connection adopts conventional connection methods in the prior art. The electrical equipment is connected to an external safe power source. These will not be described in detail here.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
