Description

Technical Field

[0001] The utility model relates to the technical field of gas treatment equipment, in particular to a spray-type ammonia water absorption tower. Background Art

[0002] The spray-type absorption tower is a commonly used device in gas treatment operations. During use, the gas will be unevenly distributed on the tower cross-section during its upward movement inside the tower. The gas velocity distribution form of the gas is: small on the side of the inner wall and large in the center. There will be a wall flow phenomenon where the liquid flowing down to the packing layer will flow along the side of the inner wall of the tower body, resulting in the packing in the central part of the packing layer not being wetted by the liquid and existing in a dry pile, so that the gas-liquid two-phase in the packing tower cannot be fully contacted, thereby reducing the working efficiency of the packing tower. In order to enable the gas and liquid to be fully and evenly contacted for mixing, a redistributor needs to be installed inside the tower between sections of the packing tower. Through the redistributor, the gas-liquid in the tower can be evenly mixed;

[0003] In the prior art, the redistributor inside the absorption tower is mostly a trough-type redistributor, and its distribution range cannot be changed and adjusted during liquid redistribution. During the liquid redistribution operation, the upper liquid is collected and processed by the redistributor and then enters the next packing area from the lower part of the redistributor for ammonia absorption operation. However, the position where it enters the packing area is fixed, and the liquid is mostly put in at a fixed position during re-injection, resulting in its flow path mostly starting from this position, so that the packing at other positions cannot give full play to its role. Therefore, a spray-type ammonia water absorption tower is proposed to solve this problem. Content of the Utility Model

[0004] In view of this, the utility model provides a spray-type ammonia water absorption tower, which can cooperate with a first distributor assembly and a second distributor assembly that have the same structure and are rotated 90 degrees out of alignment to redistribute the upper spray liquid. Thus, under the cooperation of the two, the liquid is evenly distributed on the lower packing mechanism below, so that the upper part of the lower packing mechanism can give full play to its role.

[0005] To solve the above technical problems, the utility model provides a spray-type ammonia water absorption tower, which includes a tower body, an upper packing mechanism, a lower packing mechanism, and a spray mechanism. A redistributor structure is also provided inside the tower body. The redistributor structure includes an upper connector fixed inside the tower body. A first distributor assembly and a second distributor assembly are sequentially and fixedly connected below the upper connector. The first distributor assembly and the second distributor assembly have the same structure and are rotated 90 degrees out of alignment;

[0006] Then, the first distributor assembly and the second distributor assembly, which have the same structure and are rotated 90 degrees, cooperate with each other to redistribute the upper spray liquid. With the cooperation of the two, the liquid is evenly distributed on the lower filling mechanism below, so that the upper part of the lower filling mechanism can fully play its role.

[0007] The first distributor assembly includes a mounting frame, in which a plurality of groups of rotating blades are rotatably arranged, one side of the corresponding mounting frame is provided with a driving device for driving the rotating blades to rotate, and the other side is provided with a linkage rod structure for driving the rotating blades to be linked;

[0008] Then, under the connection of the linkage rod structure, the angle of the rotating blades is changed synchronously.

[0009] There are two groups of rotating blades, each group of rotating blades has three rotating blades, and each rotating blade is provided with a support shaft fixed thereto and supporting its rotation, both ends of the corresponding support shaft are arranged through the mounting frame, one end of which is transmission-connected to the driving device, and the other end of which is transmission-connected to the linkage rod structure;

[0010] Then, the rotation angles of the two groups of rotating blades can be adjusted synchronously driven by the connecting rod structure.

[0011] The support shafts are of consistent horizontal height and are arranged in sequence. The linkage rod structure includes a first connecting plate fixedly arranged on the support shaft in the middle position, and a second connecting plate and a third connecting plate are respectively connected to the support shafts on both sides. The second connecting plate and the third connecting plate have the same structure and are mirror-arranged with each other. The first connecting plate is respectively rotatably provided with a first connecting rod rotatably connected to the second connecting plate and a second connecting rod rotatably connected to the third connecting plate.

[0012] The support shaft at the middle position is fixedly connected to the rotation center of the first connecting plate, and the support shafts on both sides are respectively fixed to the end of the second connecting plate and the end of the third connecting plate.

[0013] The driving device comprises a transmission device box fixedly arranged on one side of the mounting frame, a supporting shaft in the middle of each set of rotating blades is transmission-connected to the transmission device box, and a driving motor transmission-connected thereto is fixedly arranged on one side of the transmission device box.

[0014] In addition, an annular mounting platform for connecting to the tower body is provided at the bottom of the mounting frame of the second distributor assembly.

[0015] The beneficial effects of the above technical solution of the utility model are as follows:

[0016] The first distributor assembly and the second distributor assembly, which have the same structure and are arranged with a 90-degree misaligned rotation, cooperate to redistribute the upper spray liquid. Thus, with their cooperation, the liquid is evenly distributed on the lower packing mechanism below, enabling the upper part of the lower packing mechanism to fully play its role.

[0017] Under the driving force provided by the driving device, each group of rotating blades is driven to rotate by the linkage rod structure connected to the other end of the support shaft, so that the angle of the rotating blades can be adjusted. Furthermore, during the process of changing their angles, the falling position of the spray liquid is changed, enabling it to be evenly distributed on the lower packing mechanism below.

[0018] The transmission equipment box is respectively connected to the support shafts at the middle position of each group for transmission. Then, it is driven to rotate by the driving motor, so that each group of rotating blades can be simultaneously controlled to rotate, enabling them to rotate at different angles during operation to increase the usage efficiency of the lower packing structure below.

[0028] Then, the first distributor assembly 52 and the second distributor assembly 53, which have the same structure and are rotated 90 degrees, cooperate with each other to redistribute the upper spray liquid. With the cooperation of the two, the liquid is evenly distributed on the lower filling mechanism 3 below, so that the upper part of the lower filling mechanism 3 can fully play its role.

[0029] like Figure 2 , 3 As shown in FIG. 4 , the first distributor assembly 52 includes a mounting frame 521, in which a plurality of groups of rotating blades 522 are rotatably arranged. One side of the corresponding mounting frame 521 is provided with a driving device 523 for driving the rotating blades 522 to rotate, and the other side is provided with a linkage rod structure 524 for driving the rotating blades 522 to link with each other;

[0030] Then, under the connection of the linkage rod structure 524, the rotating blades 522 are caused to change their angles synchronously.

[0031] like Figure 3 , 4 As shown, there are two groups of rotating blades 522, each group of rotating blades 522 has three rotating blades, and each rotating blade 522 is provided with a support shaft 525 fixed thereto and supporting its rotation, and both ends of the corresponding support shaft 525 are arranged through the mounting frame 521, one end of which is transmission-connected to the driving device 523, and the other end is transmission-connected to the linkage rod structure 524;

[0032] Furthermore, the rotation angles of the two groups of rotating blades 522 can be adjusted synchronously under the drive of the connecting rod structure. The rotation directions of the two groups of rotating blades 522 are set to be opposite, and the corresponding two groups of linkage rod structures 524 should be symmetrically arranged. In addition, liquid passing holes can be opened on the rotating blades 522 to improve the liquid distribution efficiency.

[0033] As Figure 5 shown, the horizontal heights of the support shafts 525 are the same and are arranged in sequence. The linkage rod structure 524 includes a first connecting plate 5241 fixedly arranged on the support shaft 525 at the middle position. A second connecting plate 5242 and a third connecting plate 5243 are respectively connected to the support shafts 525 on both sides.

[0036] During use, the ammonia gas to be absorbed is introduced into the tower body 1 through the air inlet at the lower part of the tower body 1. The gas passes through the lower packing mechanism 3, the redistributor structure 5, and the upper packing mechanism 2 from bottom to top and is discharged from the air outlet, while the liquid sprayed by the spraying mechanism 4 passes through the upper packing mechanism 2, the redistributor structure 5, and the lower packing mechanism 3 from top to bottom and falls to the bottom of the tower body 1. The gas is fully absorbed and treated during this process;

[0037] The working principle of the redistributor structure 5 is that the driving motor 5232 provides power output, which is then transmitted into the transmission equipment box 5231, causing it to drive the two support shafts 525 to rotate, thereby driving the rotating blades 522 to rotate, changing the blade angles, and increasing the liquid distribution efficiency.

[0038] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
