Description

Technical Field

[0001] This utility model relates to the field of deacidification equipment technology, and in particular to the cone of a multifunctional tower air distributor for rapid deacidification. Background Technology

[0002] The rapid cooling and acid removal tower is a core piece of equipment in industrial flue gas purification systems. It is mainly used to rapidly cool down and remove acidic substances from high-temperature acidic flue gas generated by waste incineration, industrial kilns, etc.

[0003] In the process of incinerating solid waste such as municipal solid waste and medical waste, flue gas containing acidic gases and highly toxic substances such as dioxins is generated. If directly emitted, it will cause serious environmental pollution and endanger human health. Therefore, the quenching deacidification tower has become the core equipment for flue gas purification, and the performance of its air distribution structure directly determines the cooling and deacidification effect.

[0004] While existing rapid cooling deacidification tower air distribution structures achieve airflow treatment and guidance, some structures rely on a single air inlet and spray design, resulting in short contact time between the airflow and the alkaline spray medium, and insufficient mixing when the acid concentration of heavily polluted flue gas is high. Although some have improved air inlet methods, the air distribution components have poor guiding effect, uneven airflow distribution, and are prone to spray dead zones. At the same time, the connection between the tower body and the air distribution components is mostly a fixed structure, which is inconvenient for disassembly and maintenance, and has low waste liquid discharge efficiency, resulting in limited overall treatment efficiency and difficulty in meeting the requirements of high-efficiency purification. Therefore, a multifunctional rapid cooling deacidification tower air distributor cone is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a multifunctional tower air distributor cone for rapid cooling and deacidification, comprising a deacidification tower body 1, which serves as the main supporting structure for deacidification treatment, providing installation space for internal components and guiding airflow and material flow. An air distributor cone 2 is sleeved and connected to the bottom end of the deacidification tower body 1 to guide and distribute the incoming airflow, ensuring more uniform airflow participation in subsequent processing. A connecting bolt 3 is threaded between the air distributor cone 2 and the deacidification tower body 1, achieving a stable assembly, facilitating disassembly and maintenance, and ensuring the sealing and structural strength of the connection. A spiral guide assembly 5 is provided inside the air distributor cone 2 to spirally guide the airflow, prolonging the residence time of the airflow within the tower and enhancing contact with other media. The spiral guide assembly 5 includes a spiral guide plate 51. The main supporting structure guides the airflow along a spiral path. The outer wall of the spiral guide plate 51 is fixedly connected to the inner wall of the air distributor cone 2, thus fixing the spiral tube 52 to the air distributor cone 2 and ensuring structural stability. The inner wall of the spiral guide plate 51 is fixedly connected to the outer wall of the conical column 43, making the spiral tube 52 and the conical column 43 form an integral structure, enhancing the guiding effect and structural strength. The spiral tube 52 is fixedly connected to the upper surface of the spiral guide plate 51, further strengthening the spiral guiding effect on the airflow and improving the uniformity of airflow distribution. One end of the spiral tube 52 passes through the outer wall of the air distributor cone 2 and is fixedly connected to the air inlet pipe 53, which is used to introduce the airflow to be treated into the spiral guide assembly 5, providing a channel for the airflow to enter the tower. The other end of the spiral tube 52 is provided with an air outlet 54 for the airflow after spiral guidance to be discharged and enter the next processing stage.

[0031] Reference Figures 1-3A drain valve pipe 6 is fixedly connected to the lower edge of the outer wall of the air distributor cone 2 to drain the liquid accumulated in the tower, facilitating control of the liquid level in the tower and timely discharge of waste liquid after reaction. The air distributor cone 2 is equipped with a rapid cooling spray assembly 4, which is used to cool and pre-treat the airflow. A spiral guide assembly 5 is used to guide the subsequent airflow; the two work together to improve processing efficiency. The rapid cooling spray assembly 4 includes a first liquid supply pipe 41 and a second liquid supply pipe 42, which provide spray media for different spray structures to achieve staged spray treatment. The nozzles are fixedly connected to the outer wall of the air distributor cone 2 from bottom to top, and installed in an upward and downward order to create a layered effect in the spraying process and enhance the contact effect with the airflow. A conical column 43 is fixedly connected to the inner end of the first liquid supply pipe 41, serving as the mounting carrier for the first nozzle 44 and also guiding the airflow. The first nozzle 44 is fixedly connected to the outer surface of the conical column 43 to atomize and spray the medium transported by the first liquid supply pipe 41, ensuring full contact with the airflow. Multiple first nozzles 44 are provided, and the multiple first nozzles 44 are arranged in a spiral pattern. The spiral arrangement allows the sprayed medium to... The spray pattern provides a wider coverage area and improves the uniformity of contact with the airflow. An annular spray pipe 45 is fixedly connected to the inner end of the second supply pipe 42 to evenly distribute the medium from the second supply pipe 42 to each spray branch pipe 46, thus expanding the spray coverage area. Spray branch pipes 46 are fixedly connected between the inner wall of the annular spray pipe 45 and the outer wall of the conical column 43 to assist the annular spray pipe 45 in spraying the medium, enhancing the comprehensiveness of the spray. Four spray branch pipes 46 are arranged in a cross shape, which ensures that the spray medium is evenly distributed in the radial direction, avoiding spray dead zones. Furthermore, the interiors of the four spray branch pipes 46 are connected to the interiors of the annular spray pipe 45, ensuring that the medium can flow smoothly from the annular spray pipe 45 into the spray branch pipes 46 to achieve synchronous spraying. The upper surfaces of the spray branch pipes 46 and the annular spray pipe 45 are fixedly connected with second nozzles 47, which are used to atomize and spray the medium in the annular spray pipe 45 and the spray branch pipes 46, further contacting and reacting with the airflow. There are multiple second nozzles 47, and all of the second nozzles 47 are set at an angle. The angle setting can make the spraying direction of the spraying medium more in line with the airflow path, improving the contact efficiency and reaction effect.

[0032] Working principle: The airflow to be treated enters the spiral guide assembly 5 through the inlet pipe 53. Under the combined action of the spiral guide plate 51 and the spiral tube 52, it flows along the spiral path, prolonging the residence time of the airflow in the air distributor cone 2, and achieving initial uniform distribution of the airflow. Subsequently, the airflow flows upward and passes through the second nozzle 47 and the first nozzle 44 area of ​​the rapid cooling spray assembly 4 in sequence. The spray medium delivered by the second liquid supply pipe 42 is distributed to the cross-shaped spray branch pipes 46 through the annular spray pipe 45, and then atomized and sprayed out through multiple second nozzles 47 arranged at an angle, making full contact with the rising airflow. The initial cooling and reaction are completed. Then, the spray medium delivered by the first liquid supply pipe 41 is atomized and sprayed out through multiple first nozzles 44 arranged in a spiral on the outer surface of the conical column 43, further contacting the airflow and enhancing the cooling and deacidification effect. The waste liquid generated during the process is collected at the bottom of the air distributor cone 2 and discharged through the drain valve pipe 6. The airflow after rapid cooling and deacidification finally enters the deacidification tower 1 for subsequent treatment. The entire process, through the cooperation of the spiral guide component 5 and the staged spray structure, significantly improves the contact efficiency and reaction effect between the airflow and the spray medium, realizing a highly efficient rapid cooling and deacidification function.
