[0031] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0032] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be exchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a category and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0033] The distributor assembly and the absorption tower provided by the embodiments of the present application will be described in detail below with reference to the drawings and specific embodiments and application scenarios.

[0034] Reference Figures 1-15The distributor assembly provided by the embodiments of the present application can be arranged in the absorption tower body of the absorption tower, and can be used to uniformly distribute the fluid entering the absorption tower to the lower side of the distributor assembly, such as uniformly distributing the gas (flue gas) entering the absorption tower to the lower side of the distributor assembly, thereby improving the processing effect of the absorption tower on the fluid.

[0035] As shown in Figure 6 The distributor assembly can include a distributor 300, a support beam 100, and a protective piece 400. Both ends of the support beam 100 can be used to be connected with the inner wall of the absorption tower body. At least part of the protective piece 400 can be located between the support beam 100 and the distributor 300, and is connected with the support beam 100 and the distributor 300 respectively. The orthogonal projection of the protective piece 400 covers the orthogonal projection of the support beam 100 in the direction from the distributor 300 to the support beam 100. In addition, the material of the protective piece 400 is a corrosion-resistant material. Optionally, the material of the protective piece 400 can be polytetrafluoroethylene material or polyurethane material or epoxy resin material, or other materials that can have a corrosion prevention effect.

[0036] In the embodiments of the present application, at least part of the protective piece 400 is located between the support beam 100 and the distributor 300, which can separate the distributor 300 and the support beam 100, so as to effectively reduce the friction between the distributor 300 and the support beam 100, thereby reducing the wear of the support beam 100 by the distributor 300. In addition, the material of the protective piece 400 is a corrosion-resistant material. The orthogonal projection of the protective piece 400 covers the orthogonal projection of the support beam 100 in the direction from the distributor 300 to the support beam 100, that is, the protective piece 400 can shield the support beam 100 to prevent the acidic slurry from directly dropping on the support beam 100, thereby protecting the support beam 100 to reduce the corrosion of the acidic slurry on the support beam 100, thereby prolonging the service life of the support beam 100.

[0037] In the optional embodiments, as shown in Figure 11 The protective piece 400 can wrap the support beam 100. In this way, the support beam 100 can be protected from the external environment, such as preventing the support beam 100 from being corroded by the acidic slurry, and isolating moisture to prevent the support beam 100 from rusting, thereby further improving the protection effect of the support beam 100, thereby further prolonging the service life of the support beam 100.

[0038] Of course, the protective piece 400 can not wrap the support beam 100, for example, the protective piece 400 can be arranged only on the upper part of the support beam 100 to shield the support beam 100.

[0039] In optional embodiments of the present application, the distributor assembly can further comprise a shock-absorbing member 700, which can be located between the distributor 300 and the protective member 400, and the two ends of the shock-absorbing member 700 can be connected with the distributor 300 and the protective member 400 respectively. The shock-absorbing member 700 in this embodiment can serve as a buffer to reduce the impact of the vibration generated by the distributor 300 during operation on the protective member 400 and the support beam 100, thereby protecting the protective member 400 and the support beam 100 from being damaged due to the vibration of the distributor 300. At the same time, the connection of the shock-absorbing member 700 with the distributor 300 and the protective member 400 respectively can improve the connection strength of the distributor 300 and the protective member 400, thereby enhancing the structural stability of the entire assembly and preventing loosening or fatigue caused by vibration.

[0040] In other embodiments, the distributor assembly can also not comprise a shock-absorbing member 700.

[0041] In optional embodiments, as shown in Figure 14 the shock-absorbing member 700 can comprise a limiting rod 710 and an elastic member 720, the two ends of the limiting rod 710 can be connected with the distributor 300 and the protective member 400 respectively, and the elastic member 720 can be sleeved outside the limiting rod 710, and the two ends of the elastic member 720 can be connected with the distributor 300 and the protective member 400 respectively. In this embodiment, the elastic member 720 can serve as a buffer to reduce the transmission of vibration generated by the distributor 300 during operation to the protective member 400, and the limiting rod 710 can limit the deformation range of the elastic member 720 to ensure that the elastic member 720 performs shock-absorbing work within a reasonable range. When the distributor 300 is shaken by the impact of airflow, the elastic member 720 will not be deformed excessively under the constraint of the limiting rod 710, which not only ensures the shock-absorbing effect but also prevents the elastic member 720 from being damaged due to excessive stretching or compression, thereby prolonging the service life of the elastic member 720 and making the shock-absorbing system more stable and reliable. Optionally, the elastic member 720 can be a spring.

[0042] Optionally, the limiting rod 710 can have a telescopic structure. In this way, when the distributor 300 is displaced by the impact of airflow, the limiting rod 710 can first serve as a buffer in a telescopic manner to reduce the instantaneous impact force, and then limit the further displacement of the distributor 300 or the protective member 400, thereby more effectively protecting the distributor 300 or the protective member 400 from being damaged by severe impact. At the same time, the telescopic limiting rod 710 can more evenly share the stress and impact force between the distributor 300 and the protective member 400, thereby reducing the problem of local stress concentration caused by the fixation of the limiting rod 710. Of course, the limiting rod 710 can also not have a telescopic structure.

[0043] Here, the limiting rod 710 can include a first limiting rod 711 and a second limiting rod 712, the first limiting rod 711 can be connected with the protective piece 400, the second limiting rod 712 can be connected with the distributor 300, and the second limiting rod 712 is telescopically connected with the first limiting rod 711. Wherein, both ends of the limiting rod 710 can be respectively provided with a first connecting part 730 and a second connecting part 740, the first connecting part 730 and the second connecting part 740 can each include a screw rod, the screw rod of the first connecting part 730 can be connected with the protective piece 400, and the screw rod of the second connecting part 740 can be connected with the distributor 300.

[0044] In the embodiment, through the synergistic effect of the limiting rod 710 and the elastic piece 720, the vibration impact force transmitted from the distributor 300 to the protective piece 400 is reduced, and the problems such as fatigue damage, cracks, and even breakage of the protective piece 400 and the distributor 300 due to long-term vibration impact are prevented, thereby achieving good protection for the protective piece 400 and the distributor 300.

[0045] In other embodiments, the damping piece 700 can also be a silica gel pad or a rubber pad.

[0046] In some embodiments, the distributor 300 can be connected with the support beam 100 through a plurality of fixing pieces 500. Specifically, the distributor 300 can be provided with a plurality of mounting holes, the protective piece 400 can be provided with a plurality of through holes, the plurality of through holes can correspond to the plurality of mounting holes one by one, and each fixing piece 500 can be connected with the support beam 100 and then sequentially pass through the corresponding through hole and mounting hole to be connected with the nut, thereby achieving the connection between the support beam 100 and the distributor 300. Alternatively, the damping piece 700 can only include the elastic piece 720, the elastic piece 720 can be sleeved outside the fixing piece 500, and the fixing piece 500 can limit the elastic piece 720 to prevent the elastic piece 720 from being damaged due to excessive stretching or compression.

[0047] In the embodiment, in order to further reduce the wear degree of the support beam 100, the distributor 300, and the protective piece 400, a first gasket 510 can be arranged between the support beam 100 and the protective piece 400, and a second gasket 520 can be arranged between the distributor 300 and the nut.

[0048] In the optional embodiment, as Figure 13As shown, the support beam 100 can be provided with an inner cavity 101, and a plurality of reinforcing plates 130 can be arranged in the inner cavity 101. The reinforcing plates 130 are spaced apart along the length direction of the support beam 100, and each of the reinforcing plates 130 is connected to the top wall of the support beam 100 and the side wall of the support beam 100. In this embodiment, the reinforcing plates 130 can improve the bending stiffness of the support beam 100, thereby improving the overall strength. In addition, the spaced-apart reinforcing plates 130 can disperse the load and avoid local stress concentration of the support beam 100, thereby improving the load-carrying capacity of the support beam 100. At the same time, since the support beam 100 is provided with the inner cavity 101, the strength of the support beam 100 can be ensured while reducing the use of materials to reduce the weight of the support beam 100.

[0049] Of course, the support beam 100 can also be a solid structure.

[0050] In optional embodiments, the distributor assembly can further include a reinforcing column. The reinforcing column can be located on the side of the support beam 100 away from the distributor 300. A first end of the reinforcing column can be used to connect to the inner wall of the absorption tower body, a second end of the reinforcing column can be connected to the middle position of the support beam 100, and the length direction of the reinforcing column intersects the length direction of the support beam 100. In this way, the stability and load-carrying capacity of the support beam 100 can be improved.

[0051] Of course, the distributor assembly can also not include a reinforcing column.

[0052] In optional embodiments, as shown in Figure 12 The distributor assembly can include a plurality of support beams 100 and a plurality of protective members 400. Each protective member 400 corresponds to each support beam 100. Both ends of each support beam 100 can be used to connect to the inner wall of the absorption tower body. In this way, the support effect of the distributor 300 can be improved, thereby improving the stability of the fixed distributor 300. Of course, the distributor assembly can also include only one support beam 100 and one protective member 400.

[0053] In addition, at least one reinforcing beam 600 can be arranged between adjacent two support beams 100. In this way, the overall stiffness and strength of the support beam 100 can be improved, and the anti-vibration and anti-impact capacity of the support beam 100 can be improved.

[0054] Of course, reinforcing beams 600 can also not be arranged between adjacent two support beams 100.

[0055] In optional embodiments of the present application, as shown in Figure 13As shown, the side of the support beam 100 close to the distributor 300 can be provided with a first anticorrosion layer 110, and the outer surface of the support beam 100 except the side close to the distributor 300 can be provided with a second anticorrosion layer 120. In this way, the anticorrosion effect of the support beam 100 can be improved. Of course, the first anticorrosion layer 110 can be provided only on the side of the support beam 100 close to the distributor 300, and the outer surface of the support beam 100 except the side close to the distributor 300 can not be provided with an anticorrosion layer.

[0056] Optionally, the thickness of the first anticorrosion layer 110 is greater than the thickness of the second anticorrosion layer 120. For example, the thickness of the first anticorrosion layer 110 can be twice the thickness of the second anticorrosion layer 120. In this way, the use of anticorrosion materials can be saved on the basis of ensuring the anticorrosion effect of the support beam 100, thereby facilitating cost reduction. Of course, the thickness of the first anticorrosion layer 110 can also be less than or equal to the thickness of the second anticorrosion layer 120.

[0057] In optional embodiments of the present application, the support beam 100 can be provided with a corrosion detection element. The corrosion detection element can be used to detect the corrosion state of the support beam 100 and can be in communication connection with the display device of the absorption tower. In this way, the corrosion state of the support beam 100 can be monitored, and the corrosion degree of the support beam 100 at different time points can be obtained. Compared with artificial periodic inspection, the corrosion condition of the support beam 100 can be grasped more timely, and important corrosion change information can be avoided to be missed due to too long inspection period, thereby causing damage to the support beam 100. At the same time, through real-time monitoring of the corrosion state, once the corrosion degree of the support beam 100 approaches or exceeds a safety threshold, the corrosion detection element can timely send a warning signal to the display device of the absorption tower to remind the staff to take timely measures, thereby avoiding the decrease of structural strength of the support beam 100 due to excessive corrosion, and further causing the collapse of the distributor 300 in the absorption tower and other serious safety accidents.

[0058] In other embodiments, the support beam 100 can also not be provided with a corrosion detection element.

[0059] In optional embodiments, the corrosion detection element can be a fiber optic corrosion sensor or a resistive corrosion sensor. Alternatively, the corrosion detection element can be an ultrasonic detection device, which can be disposed in the inner cavity 101 of the support beam 100. Specifically, the ultrasonic detection device can include an ultrasonic transducer and a linear actuator that drives the ultrasonic transducer to move along the length of the support beam 100. The ultrasonic waves emitted by the ultrasonic transducer can be directed towards the upper wall of the support beam 100. After being reflected by the upper wall of the support beam 100, the ultrasonic waves return to the ultrasonic transducer. The time interval between the ultrasonic transducer emitting the ultrasonic waves and receiving the returned ultrasonic waves can be used to detect whether the upper wall of the support beam 100 has been corroded and formed holes. Of course, the corrosion detection element can also be a monitor installed in the inner cavity 101 of the support beam 100 to determine the degree of corrosion of the support beam 100 by acquiring images of the inside of the support beam 100 in real time.

[0060] In optional embodiments, such as Figure 7 As shown, the distributor assembly may further include an annular fixed beam 200, which can be connected to the inner wall of the absorption tower body. For example, the annular fixed beam 200 can be connected to the inner wall of the absorption tower body using multiple bolts. The outer diameter of the annular fixed beam 200 can be equal to the inner diameter of the absorption tower body, meaning the outer wall of the annular fixed beam 200 can fit snugly against the inner wall of the absorption tower body, thereby improving the connection stability between the annular fixed beam 200 and the absorption tower body. Both ends of the support beam 100 can be connected to the annular fixed beam 200. Specifically, both ends of the support beam 100 can be welded to the annular fixed beam 200, thus achieving the connection between the support beam 100 and the absorption tower body.

[0061] Furthermore, the annular fixed beam 200 can be provided with multiple fixing parts 210, each fixing part 210 can be evenly distributed along the circumference of the annular fixed beam 200, and each fixing part 210 can be connected to the distributor 300. This arrangement can further improve the stability of the distributor 300. In this embodiment, the distributor assembly can also include multiple clamping plates 220, each clamping plate 220 can be connected to the base plate 301 of the distributor 300 by bolts, and, as... Figure 4 As shown, each clamping plate 220 and the base plate 301 of the distributor 300 can form a clamping space for the corresponding fixing part 210 to be embedded, thereby realizing the connection between the distributor 300 and the fixing part 210. With this configuration, the connection between the fixing part 210 and the distributor 300 can be realized without opening mounting holes on the fixing part 210, which helps to improve the strength of the fixing part 210.

[0062] Optionally, in order to prevent the annular fixing beam 200 from being corroded, the outer surface of the annular fixing beam 200 is provided with a corrosion-proof layer. Further optionally, the thickness of the corrosion-proof layer on the upper surface of the fixing portion 210 can be greater than the thickness of the corrosion-proof layer at other positions of the fixing portion 210, so that the use of corrosion-proof materials can be saved on the basis of ensuring the corrosion-proof effect.

[0063] In optional embodiments, as shown in Figure 1 Each distribution module 310 can be provided with a plurality of outlets 302 on the bottom plate 301, so as to facilitate the fluid above the distributor 300 to flow into the lower part of the distributor 300. Adjacent distribution modules 310 can be connected by bolts.

[0064] In the embodiment, the plurality of distribution modules 310 can include a plurality of edge modules 312 and a plurality of intermediate modules 311. The outer edge of each edge module 312 can be adapted to the shape of the absorption tower body and fit the inner wall of the absorption tower body. Here, the projection of each intermediate module 311 in the vertical direction can be a rectangle.

[0065] Optionally, as shown in Figure 15 Each intermediate module 311 can include a bottom plate 301, a side plate 303 and a reinforcing rib plate 304. The bottom plate 301 is provided with an outlet 302. The reinforcing rib plate 304 can be connected with the side plate 303 and the bottom plate 301 to improve the strength of each intermediate module 311. In addition, adjacent two intermediate modules 311 can be connected by the side plates 303. Of course, each edge module 312 can also include a bottom plate 301 and a side plate 303. Each edge module 312 can be connected with the side plate 303 of the adjacent edge module 312 or intermediate module 311. Each edge module 312 can also include a reinforcing rib plate 304 connected with the bottom plate 301 and the side plate 303 to improve the structural stability of the edge module 312.

[0066] Based on the distributor assembly provided by the embodiments of the present application, the embodiments of the present application further provide an absorption tower. The absorption tower can include an absorption tower body and the distributor assembly of any of the above embodiments. The distributor assembly can be located in the absorption tower body, and the support beam 100 of the distributor assembly can be connected with the inner wall of the absorption tower body.

[0067] The absorption tower provided by the embodiments of the present application achieves the same beneficial effects as the absorption tower assembly provided by the embodiments of the present application. Here, the description is omitted.
