[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0028] Reference Figure 1 , which is the first embodiment of the utility model, and this embodiment provides a flue gas desulfurization absorption tower, which can achieve a desulfurization effect, and includes a main body component 1, including a tower body 11, a tower head 12 arranged at the upper end of the tower body 11, and a smoke inlet 13 arranged at the lower side of the outer end of the tower body 11, an arc-shaped smoke inlet pipe 14 is arranged in the smoke inlet 13, a water inlet hole 15 and a rotating shaft hole 16 are opened at the outer end of the tower body 11, a water delivery component 2 is arranged in the water inlet hole 15, a driving component 3 is arranged in the rotating shaft hole 16, and a desulfurization component 4 is arranged inside the tower body 11.

[0029] Specifically, a T-shaped channel 17 is opened inside the tower head 12 , and the lower end surface of the T-shaped channel 17 is connected to the internal channel of the tower body 11 .

[0030] Furthermore, the curved smoke inlet pipe 14 is designed, and the flat structure is conducive to the flow of smoke, reduces resistance, and improves the efficiency of the flue. The main reasons are as follows: Optimization of flow characteristics: The flat flue structure reduces the bends and mutations of the flow, making it easier for the smoke to flow along the design direction, which avoids unnecessary vortices and turbulence, because they will increase the resistance of the flow; Reduce mutations: In traditional circular or cylindrical flues, the flow of smoke often produces vortices at turns or cross-sectional changes. These vortices not only increase the resistance of the flow, but may also cause the separation of the smoke and affect the stability of the smoke flow. The flat flue structure reduces such flow mutations, thereby reducing resistance; Cross-sectional optimization: The cross-sectional area of ​​the flat flue is relatively small, which means that the friction between the gas and the flue wall during the flow process is reduced. This design can significantly reduce the flow resistance, thereby improving the flow efficiency of the smoke; Design flexibility: The flat flue structure allows the designer to optimize the length and width of the flue according to actual needs, so as to better adapt to various application scenarios and working conditions. This flexibility helps to further improve the efficiency of the flue. Structural stability: The flat structural design also improves the structural stability of the flue. Due to its shape and material selection, the flat flue can withstand greater gas pressure and temperature changes, reducing the additional resistance caused by structural instability. In summary, the flat structure effectively reduces flow resistance and improves the efficiency of the flue by optimizing the flow characteristics of flue gas, reducing mutations, cross-sectional optimization, design flexibility and structural stability. This design has been widely used in industrial desulfurization tower equipment because it helps reduce energy consumption and maintenance costs and improve the overall efficiency of the equipment.

[0031] Furthermore, the T-shaped channel 17 opened inside the tower head 12 can reduce the resistance of the airflow and lower the pressure drop, thereby increasing the speed and efficiency of the flue gas passing through the desulfurization tower.

[0032] Furthermore, the driving component 3 drives the desulfurization component 4 to operate, so that the desulfurization tower has a desulfurization function. With the help of the setting of the water delivery component 2, the desulfurization effect is enhanced and the practicality is improved.

[0033] In summary, by reasonably designing the size and shape of the absorption tower flue, the pressure loss of the desulfurization tower equipment is reduced to a minimum, thereby minimizing the induced draft function consumption. By accurately simulating the gas flow field in the absorption tower and adopting an optimized airflow distribution design, the tower diameter, tower height and other factors are reasonably designed, and the optimal empty tower velocity, gas residence time and other key process parameters are determined to achieve maximum desulfurization efficiency. This provides reliable guarantees for the economic and high-quality operation of the desulfurization system in a more economical and energy-saving way, while taking into account environmental protection and social benefits, and further reducing the production costs of the enterprise. Example 2

[0034] Reference Figure 2 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a multifunctional operation guarantee for the flue gas desulfurization absorption tower, which includes a water delivery component 2 including a water inlet pipe 21 arranged in the water inlet hole 15, a water storage tank 22 arranged at the lower end of the water inlet pipe 21, and a fixed pipe 23 arranged at the other end of the water inlet pipe 21, and a T-shaped groove 24 is opened at the lower end of the fixed pipe 23.

[0035] Specifically, the driving assembly 3 includes a rotating shaft 31 disposed in the rotating shaft hole 16 , a bevel gear 32 disposed on one side of the rotating shaft 31 close to the desulfurization assembly 4 , and a motor 33 disposed on the other end of the rotating shaft 31 .

[0036] Specifically, the desulfurization assembly 4 includes a smoke blocking plate 41 arranged on the inner wall of the tower body 11 , a threaded shaft 42 arranged at the bottom end of the inner part of the tower body 11 , and a bevel gear 43 arranged on the outer wall of the threaded shaft 42 .

[0037] Specifically, a threaded pipe 47 is provided at the upper end of the lower water pipe 44, an upper water pipe 48 is provided at the upper end of the threaded pipe 47, a disc 49 is provided at the upper end of the upper water pipe 48, the interior of the disc 49 is provided as a cavity structure, and a second nozzle 491 is provided at the lower end of the disc 49.

[0038] Furthermore, the lower water pipe 44 is threadedly connected to the threaded shaft 42 to achieve up and down lifting movement, thereby providing a power source for the up and down movement of the lower water pipe 44 .

[0039] Furthermore, the water inlet pipe 21 is designed as an L-shaped structure, the fixed pipe 23 is connected to one end of the water inlet pipe 21, and the other end of the water inlet pipe 21 is connected to the water storage tank 22, thereby providing operation guarantee for the water transportation in the upper water pipe 48 on the lower side of the fixed pipe 23.

[0040] Furthermore, the motor 33 drives the rotating shaft 31 to rotate, driving the bevel gear 32 to rotate. Since the bevel gear 32 is meshed with the helical gear 43, the threaded shaft 42 is driven to rotate, providing driving force for the up and down movement of the lower water pipe 44.

[0041] Furthermore, the provision of the smoke barrier 41 is conducive to preventing the spread of fire: when a fire occurs, the smoke barrier can effectively slow down the spread of the fire, buying precious time for personnel evacuation and fire rescue; reducing smoke emissions: the smoke barrier can reduce the generation of smoke during the combustion process, thereby reducing the damage caused by inhaling toxic smoke; environmental protection and health: in the process of producing flame retardant boards, due to the integrity of the wood, the use of liquid glue can be reduced, thereby reducing the content of harmful substances such as formaldehyde, making it more environmentally friendly and healthy; diversified performance: in addition to being flame retardant, the smoke barrier also has the characteristics of smoke suppression, corrosion resistance, insect resistance and stability. These properties make the smoke barrier more and more popular in modern decoration; light weight and easy processing: the smoke barrier is made of plywood, which is light and easy to process, convenient to construct, and can effectively reduce costs.

[0042] Furthermore, the provision of the threaded tube 47 is beneficial for improving the sealing and ductility of the connection between the lower water pipe 44 and the upper water pipe 48 by means of the tensile elasticity of the threaded tube 47 when the lower water pipe 44 moves downward.

[0043] In summary, the tower diameter, tower height and other factors are reasonably designed, and the key process parameters such as the optimal empty tower velocity and gas residence time are determined to achieve the maximum desulfurization efficiency. According to the actual working conditions, the number of spray layers and layer height are optimized to determine the optimal spray density and improve the spray coverage. The gas flow field in the absorption tower is accurately simulated, and an optimized airflow distribution design is adopted to ensure uniform distribution of the fluid in the tower. Example 3

[0044] Reference Figure 3-4 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a linkage effect guarantee for the flue gas desulfurization absorption tower, which includes a lower water pipe 44 provided at the upper end of the bevel gear 43, a through plate 45 provided on the outer wall of the lower water pipe 44, a first nozzle 46 provided on the outer wall of the through plate 45, and a hollow plate 451 provided inside the through plate 45.

[0045] Specifically, a movable tube 492 is provided at the upper end of the disc 49 , and a T-shaped clamp 493 is provided at the upper end of the movable tube 492 .

[0046] Furthermore, the rotation of the desulfurization component 4 is achieved by means of the mutual engagement of the T-slot 24 and the T-clip 493 .

[0047] Furthermore, a plurality of through plates 45 are arranged in a circular array along the center of the lower water delivery pipe 44 , and a plurality of first nozzles 46 are arranged in a linear array on a horizontal line of the through plates 45 .

[0048] Furthermore, the setting of the hollow plate 451, on the one hand, prevents the water of the upper water pipe 48 from directly flowing into the lower water pipe 44 below, thereby achieving the spraying effect on the first nozzle 46 on the through plate 45, and on the other hand, through the hollow setting, guides the water into the lower water pipe 44 below, thereby increasing the water source for the spraying of the second nozzle 491.

[0049] Furthermore, when the threaded shaft 42 rotates, it drives the lower water pipe 44 to rotate while realizing up and down lifting movements. When the lower water pipe 44 rotates, with the help of the fixed connection between the lower water pipe 44 and the upper water pipe 48, the disc 49 and the movable pipe 492, the lower water pipe 44 and the upper water pipe 48, the disc 49 and the movable pipe 492 and other components are driven to rotate, thereby improving the range and effect of the spraying.

[0050] In summary, the staff turns on the driving component 3 to drive the desulfurization component 4 to move, thereby achieving the desulfurization effect on the absorption tower. With the help of the setting of the water delivery component 2, the spraying effect is enhanced and the desulfurization efficiency is maximized, so that it can provide reliable guarantees for the economic and high-quality operation of the desulfurization system in a more economical and energy-saving way, while taking into account environmental protection and social benefits, further reducing the production costs of the enterprise.
