Description

Technical Field

[0001] The utility model relates to the technical field of spray devices, in particular to a spray pipe structure for an absorption tower. Background Art

[0002] In the fields of chemical industry, environmental protection, etc., absorption towers are one of the important equipment and are widely used in the absorption and purification process of gases. As a key component in the absorption tower, the structural design and performance of the spray pipe directly affect the absorption efficiency of the gas and the operating cost of the equipment. The traditional spray pipe structure often has problems such as uneven liquid distribution and poor spraying effect, which leads to reduced reaction efficiency and increased operating costs. In order to solve the above technical problems, those skilled in the art have made the following efforts. For example, the Chinese patent authorization announcement number is CN207076330U, which discloses a desulfurization tower spray device, wherein the spray device is arranged in parallel in the desulfurization tower body, and the spray device includes at least three groups of spray layers. Through the overlapping of multiple spray layers, it is ensured that the flue gas is fully washed on the cross section of the desulfurization tower, and each layer has sufficient spray coverage. However, the original nozzles of the above scheme are all 90° one-way hollow cones, and the average coverage of the single-layer spray pipe is 220%. There is still a problem of low coverage, and there is room for improvement in the structure. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a spray pipe structure for an absorption tower.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A spray pipe structure for an absorption tower comprises a connecting beam arranged on the wall of the absorption tower, a mother pipe erected on the connecting beam, branch pipes symmetrically arranged along the mother pipe, and a spray assembly connected to the ends of the branch pipes, wherein the mother pipe comprises a pipe body and interfaces arranged on both sides of the pipe body; one end of the pipe body is connected to a pipeline outside the absorption tower through a flange connector, and the other end of the pipe body is fixed to the connecting beam through a saddle; the interfaces are respectively connected to the branch pipes through winding connectors; a spray assembly is arranged on the branch pipe, and the spray assembly comprises a spray pipe I and a spray pipe II, wherein:

[0006] Spray pipe I is a 120° one-way hollow cone nozzle, installed on a branch pipe away from the tower wall;

[0007] Spray pipe II is a 90° one-way hollow cone nozzle, which is installed on the branch pipe close to the tower wall.

[0008] This technical solution improves the spray pipe structure and realizes uniform distribution and effective spraying of liquid in the absorption tower through a variety of spray components. The stability and reliability of the system are ensured through structures such as flange connectors, winding connectors and saddles, thereby improving reaction efficiency and reducing operating costs. Specifically, the connecting beam serves as a support for the spray pipe structure to ensure that the spray system is stably installed on the wall of the absorption tower; the main pipe serves as the main delivery pipeline of the spray component, responsible for transporting the liquid from outside the absorption tower to the tower, and distributing it to each spray component through branch pipes; the branch pipe branches out from the main pipe to transport the liquid to the spray component to achieve uniform distribution of the liquid; the spray component includes spray pipe I and spray pipe II, which are responsible for spraying the liquid into the absorption tower at a specific angle and shape, contacting and reacting with the gas or substance in the tower; spray pipe I (120° one-way hollow cone nozzle) allows the liquid to be sprayed at a fan angle of 120°, which is suitable for locations that require a larger coverage area and more uniform distribution; by adjusting the angle and flow rate of the nozzle, the liquid can be sprayed at a fan angle of 120°. Effective distribution in the absorption tower; Spray pipe II (90° one-way hollow cone nozzle) is similar to spray pipe I, but the spray angle is 90°, which is used for spraying in a circle near the tower wall; flange connectors are used to connect the main pipe to the pipeline outside the absorption tower to ensure a firm connection and good sealing to prevent liquid leakage; saddles are used to fix the main pipe on the connecting beam to ensure the stability of the spray system; winding connectors are used to connect the interface to the branch pipe, which has better sealing and flexibility and is easy to install and disassemble; through the layout of the main pipe and branch pipes, as well as the spray assembly, the liquid is ensured to be evenly distributed in the absorption tower to improve the reaction efficiency; the different angles of spray pipe I and spray pipe II are set to adjust the spray range and density of the liquid according to actual needs to meet different reaction requirements.

[0009] In addition, the spray pipe structure for the absorption tower proposed in the utility model also has the following additional technical features:

[0010] According to one embodiment of the utility model, the spray assembly is provided with 60 spray pipes I and 28 spray pipes II along the periphery of the absorption tower, with a coverage rate of 270%.

[0011] This technical solution achieves efficient coverage of the interior of the absorption tower by setting up 60 spray pipes I and 28 spray pipes II; ensures that the liquid can be sprayed more evenly to every corner of the absorption tower, thereby increasing the contact area with the gas or substance in the tower and the reaction efficiency; the coverage rate of 270% means that there is a certain degree of overlapping spraying between the spray pipes, ensuring that the liquid can be fully sprayed in certain key areas or corners that are difficult to cover, thereby avoiding dead corners or uncovered areas; through the reasonable arrangement of these two types of spray pipes, a specific liquid distribution pattern is formed in the absorption tower to adapt to different reaction requirements or optimize the reaction effect. The traditional original nozzles are all 90° one-way hollow cones, and the average coverage rate of single-layer spray pipes is 220%.

[0012] According to an embodiment of the utility model, the spray assembly has a wear-resistant inner lining layer with a thickness of 4 mm inside and a wear-resistant outer lining layer with a thickness of 3 mm outside.

[0013] In this technical solution, the main function of the wear-resistant inner lining layer and the outer lining layer is to protect the base material of the spray assembly and prevent it from being damaged by wear; the thicker inner lining layer is used to withstand greater wear pressure, while the outer lining layer is used to protect the inner lining layer from further erosion by the external environment.

[0014] According to an embodiment of the utility model, the main pipe and the branch pipe are an integrated structure, and at the connection or reversal point of the branch pipe, the inner surface radius of the spray assembly is at least 25 mm.

[0015] In the present technical solution, the main pipe and the branch pipe adopt an integrated structure to enhance the structural strength of the entire spray system; the larger inner surface radius of the spray component reduces the resistance of the liquid during the flow process, reduces the eddy currents and turbulences generated by the liquid at the reversal or branching points, reduces energy loss and noise, and thus improves the spray efficiency; solid particles or impurities contained in the liquid will be deposited on the pipe tower wall when flowing through the spray component. The larger inner surface radius means that the area of ​​the pipe tower wall is relatively large, thereby reducing the deposition density of particles or impurities per unit area and reducing the risk of blockage.

[0016] According to an embodiment of the utility model, the tower diameter of the absorption tower is less than 16m, and a single mother pipe is arranged on the connecting beam; the tower diameter of the absorption tower is ≥16m, and a double mother pipe is arranged on the connecting beam.

[0017] In this technical solution, when the tower diameter of the absorption tower is small (<16m), the required spray flow and pressure in the tower are relatively low, and a single mother pipe is sufficient to meet the spraying needs, because the single mother pipe ensures that the liquid is evenly distributed in a smaller space, and the cost is relatively low; when the tower diameter of the absorption tower is large (≥16m), the required spray flow and pressure in the tower will increase accordingly. In order to ensure that the liquid can be evenly and effectively sprayed into the entire tower, a higher flow and a more stable pressure are required. The double mother pipe provides a larger flow and a more uniform distribution, thereby meeting the spraying needs of large tower diameters.

[0018] According to an embodiment of the utility model, the material of the spray component is vinyl resin, alkali-free chopped strand mat, alkali-free glass fiber cloth, silicon carbide or surface felt.

[0019] In this technical solution, the materials of the spray components each have unique advantages, such as corrosion resistance, curing performance, structural stability, mechanical strength, chemical stability, high temperature resistance, wear resistance, etc. Among them: Vinyl resin is a heavy-duty anti-corrosion coating that cures at low temperatures and has good heat resistance after curing. It has a high cross-linking density and can extend the service life of the spray pipe. The construction thickness is adjustable and can be used in conjunction with fiber cloth to achieve construction effects of different thicknesses; Alkali-free chopped strands mat is made of alkali-free glass fiber yarn after chopped, and has good structural stability and strength. The melting point is as high as 1100°C, which is suitable for use in high temperature environments, easy to be fully impregnated, the product has few bubbles, and good processability, and is suitable for the production of spray pipes; Alkali-free glass fiber cloth has high mechanical strength and high elastic modulus, can withstand a large amount of stretching, compression, bending and other forces, and is not affected by chemicals. It is resistant to chemical corrosion and water erosion, and is resistant to corrosive media such as acids, alkalis, corrosive gases, has good insulation properties and a low dielectric constant, and is suitable for sprinkler pipe structures that require insulation; silicon carbide has excellent corrosion resistance, can operate stably for a long time in corrosive media such as acids, alkalis, and salts, has excellent high temperature resistance, is not easy to deform or burn through under high temperature conditions, has good fire resistance, and strong wear resistance, and is suitable for parts of sprinkler pipes that require wear resistance, such as nozzles; surface felt is used for the outer layer of the sprinkler pipe to provide additional surface protection, enhance wear resistance and corrosion resistance, and make the sprinkler pipe look smoother and more beautiful, and is suitable for locations that have requirements for appearance.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] By improving the spray pipe structure and using a variety of spray components, the uniform distribution and effective spraying of the liquid in the absorption tower can be achieved. By using structures such as flange connectors, winding connectors and saddles, the stability and reliability of the system can be ensured, thereby improving the reaction efficiency and reducing the operating cost.
