[0032] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0033] The gas distributor of this invention includes a distribution assembly 1, which includes a base plate 11, a top plate 12, and a distribution component 13. The base plate 11 and the top plate 12 are arranged at intervals in the vertical direction. One end of the distribution component 13 is connected to the base plate 11, and the other end of the distribution component 13 is connected to the top plate 12. The distribution component 13 includes a first distribution component 131 and a second distribution component 132. The first distribution component 131 and the second distribution component 132 are connected in a first direction (e.g., Figure 1 The components are symmetrically arranged in the left-right direction (as shown), with the first direction orthogonal to the up-down direction. An air inlet 14 is formed between the first distribution component 131 and the second distribution component 132. The first distribution component 131 and the second distribution component 132 are arranged symmetrically in the second direction (as shown in the left-right direction). Figure 1The direction shown is gradually closer to the air inlet 14 in the direction away from the air inlet 14. The second direction is orthogonal to the first direction and the up and down direction. The first distribution component 131 and the second distribution component 132 both include a multi-group of splitter plates 133 arranged in parallel in the first direction. Each group of splitter plates 133 includes a plurality of splitter plates 133 arranged at intervals in the second direction.

[0034] Specifically, such as Figure 1 As shown, the bottom plate 11 is located below the top plate 12. The upper end of the distribution component 13 is connected to the top plate 12, and the lower end of the distribution component 13 is connected to the bottom plate 11. The first distribution component 131 is located on the left side, and the second distribution component 132 is located on the right side. The first distribution component 131 and the second distribution component 132 are symmetrically arranged in the left-right direction. Both the first distribution component 131 and the second distribution component 132 include multiple parallel multi-group diverter plates 133. Correspondingly, the diverter plates 133 in the first distribution component 131 and the diverter plates 133 in the second distribution component 132 are symmetrically arranged. Each diverter plate 133 group includes multiple diverter plates 133 spaced apart in the front-back direction.

[0035] For ease of description, this embodiment is described using the example that both the first distribution component 131 and the second distribution component 132 include two groups of flow plates 133. From left to right, they are the first group of flow plates 1311, the second group of flow plates 1312, the third group of flow plates 1321, and the fourth group of flow plates 1322. The first group of flow plates 1311 and the fourth group of flow plates 1322 are arranged symmetrically, and the second group of flow plates 1312 and the third group of flow plates 1321 are arranged symmetrically. The first group of flow plates 1311 and the second group of flow plates 1312 are arranged in parallel, and the third group of flow plates 1321 and the fourth group of flow plates 1322 are arranged in parallel. The second group of flow plates 1312 and the third group of flow plates 1322 are arranged in parallel. The flow plate groups 1321 are arranged at intervals in the left and right directions. The interval between the second flow plate group 1312 and the third flow plate group 1321 in the left and right directions gradually decreases from front to back. The front side of the second flow plate group 1312 and the third flow plate group 1321 forms an air inlet 14. That is to say, when the gas flows from front to back, it flows through the air inlet 14 to the space between the second flow plate group 1312 and the third flow plate group 1321. During the process of the gas flowing backward between the second flow plate group 1312 and the third flow plate group 1321, some gas will flow to the left and right through the gaps between the multiple flow plates 133 in the flow plate group 133, so that the amount of gas flowing backward becomes less and less.

[0036] For example, the interval distance between the two adjacent groups of the first distribution component is the same as the interval distance between the two adjacent groups of the second distribution component, and the interval distance between the second group of baffle plates 1312 and the third group of baffle plates 1321 can be determined according to the gas flow, which is not specifically limited in the embodiment.

[0037] For example, the interval distance between the second group of baffle plates 1312 and the third group of baffle plates 1321 in the left-right direction gradually decreases from front to back, and the interval distance of the front side and the interval distance of the rear side of the second group of baffle plates 1312 and the third group of baffle plates 1321 are not specifically limited in the embodiment. The gas flow in the actual implementation is set accordingly.

[0038] Alternatively, the bottom plate 11 in the embodiment is a closed plate. Since the flue gas flows upward in the absorption tower, the bottom plate 11 is set as a closed plate in the embodiment to avoid downward flow of flue gas, reduce flow dead angle, and improve gas distribution efficiency.

[0039] In the embodiment, the first distribution component 131 and the second distribution component 132 are symmetrically arranged in the left-right direction, the interval distance between the first distribution component 131 and the second distribution component 132 in the left-right direction gradually decreases from front to back to adapt to the change that the gas amount gradually decreases from front to back, and the gas flow is better guided. Further, the first distribution component 131 includes a plurality of groups of parallelly arranged baffle plates 133, and the second distribution component 132 includes a plurality of groups of parallelly arranged baffle plates 133, so that the gas flowing to the left flows to the left through the gaps between the baffle plates 133 of the groups of baffle plates 133 in the first distribution component 131 in sequence, and the gas flowing to the right flows to the right through the gaps between the baffle plates 133 of the groups of baffle plates 133 in the second distribution component 132 in sequence. The plurality of groups of baffle plates 133 disperses the gas flow and improves the uniformity of gas distribution.

[0040] Further, in the embodiment, the first distribution component 131 and the second distribution component 132 each include a plurality of groups of baffle plates 133, and the lower ends of the plurality of groups of baffle plates 133 are connected to the bottom plate 11, and the upper ends of the plurality of groups of baffle plates 133 are connected to the top plate 12, which improves the structural strength of the distribution assembly and further improves the stability of the distribution assembly.

[0041] In some embodiments, the height of the plurality of baffle plates 133 in each group of baffle plates 133 gradually decreases in the second direction away from the gas inlet 14.

[0042] Specifically, as Figure 1As shown, the heights of the plurality of flow distribution plates 133 in each group gradually decrease from front to back along the front-back direction, that is, the height of the flow distribution plate 133 on the front side is higher, and the height of the flow distribution plate 133 on the back side is lower, to adapt to the gradual decrease of the gas flow from front to back.

[0043] For example, the specific height of the group of flow distribution plates 133 is not limited in this embodiment, and is set according to the actual implementation of the change amount of the gas during flow.

[0044] In this embodiment, the height of the plurality of flow distribution plates 133 in each group is set differently, so that the height of the flow distribution plate 133 adjacent to the gas inlet 14 is greater than the height of the flow distribution plate 133 away from the gas inlet 14, to adapt to the gradual decrease of the gas during flow from front to back, improve the flow guiding effect of the flow distribution plate 133, and further improve the uniformity of the gas distribution.

[0045] In some embodiments, each flow distribution plate 133 includes a first flow distribution plate 1331 and a second flow distribution plate 1332, one end of the first flow distribution plate 1331 is connected to the bottom plate 11, the other end of the first flow distribution plate 1331 is movably connected to one end of the second flow distribution plate 1332, and the other end of the second flow distribution plate 1332 is connected to the top plate 12.

[0046] Specifically, as shown, Figures 1-3 the lower end of the first flow distribution plate 1331 is connected to the bottom plate 11, the upper end of the first flow distribution plate 1331 is movably connected to the lower end of the second flow distribution plate 1332, and the upper end of the second flow distribution plate 1332 is connected to the lower end of the top plate 12. In this embodiment, the height of the flow distribution plate 133 is adjusted by movably connecting the second flow distribution plate 1332 to the first flow distribution plate 1331, moving the second flow distribution plate 1332 upward to adjust the extension height of the second flow distribution plate 1332.

[0047] In this embodiment, the adjustable height of the flow distribution plate 133 is not specifically limited, and can be specifically limited according to the amount of gas phase, to adapt to different amounts of gas and improve the adaptability of the gas distributor.

[0048] In some embodiments, the second flow distribution plate 1332 is movable in the up-down direction relative to the first flow distribution plate 1331, and the second flow distribution plate 1332 has a retracted position and an extended position. In the retracted position, the second flow distribution plate 1332 is completely located within the first flow distribution plate 1331, and in the extended position, the second flow distribution plate 1332 is at least partially located outside the first flow distribution plate 1331.

[0049] Specifically, as shown, Figure 2 and Figure 3As shown, when the second baffle plate 1332 is in the retracted position, the second baffle plate 1332 is located in the first baffle plate 1331, and the upper end surface of the second baffle plate 1332 can be flush with the upper end surface of the first baffle plate 1331, so as to facilitate the connection of the second baffle plate 1332 and the top plate 12, and at this time, the height of the baffle plate 133 is the smallest.

[0050] When the second baffle plate 1332 is in the extended position, the second baffle plate 1332 is moved upward relative to the first baffle plate 1331, and at least part of the second baffle plate 1332 is located in the first baffle plate 1331, at this time, the height of the baffle plate 133 is the sum of the heights of the first baffle plate 1331 and the second baffle plate 1332 located outside the first baffle plate 1331. When the gas flow is large, by moving the second baffle plate 1332 upward, the second baffle plate 1332 is at least partially located outside the first baffle plate 1331, which is suitable for the distribution of large flow gas. When the second baffle plate 1332 is moved upward to the maximum position, the lower end of the second baffle plate 1332 can be located in the first baffle plate 1331, or the lower end surface of the second baffle plate 1332 is flush with the upper end surface of the first baffle plate 1331, and the height of the baffle plate 133 is the sum of the heights of the first baffle plate 1331 and the second baffle plate 1332. When it is necessary to adjust the height of the baffle plate 133, the position of the second baffle plate 1332 is changed to adjust the height to adapt to different amounts of gas phase.

[0051] For example, the first baffle plate 1331 can be provided as a first baffle plate 1331 with a receiving cavity, and the second baffle plate 1332 can be nested in the first baffle plate 1331, or the second baffle plate 1332 is located on the inner side of the first baffle plate 1331, that is, the side away from the gas inlet 14, and the first baffle plate 1331 and the second baffle plate 1332 are connected by a driver.

[0052] For example, the first baffle plate 1331 is provided with a driver, which can adopt a telescopic rod. The second baffle plate 1332 is connected to the telescopic rod to drive the second baffle plate 1332 to move in the upward and downward directions, so as to switch the second baffle plate 1332 between the extended position and the retracted position. Alternatively, the driver is a lead screw nut, the nut is sleeved on the lead screw and connected to the second baffle plate 1332, and the nut is driven to move in the upward and downward directions by rotating the lead screw, thereby driving the second baffle plate 1332 to move in the upward and downward directions. The present embodiment does not limit the setting of the driver, as long as it can realize the adjustment of the second baffle plate 1332 in different positions in the upward and downward directions, which belongs to the protection scope of the present embodiment.

[0053] The embodiment of the present application sets the second shunt plate 1332 in the first shunt plate 1331, and the second shunt plate 1332 is movable in the up-down direction relative to the first shunt plate 1331, and the size of the second shunt plate 1332 outside the first shunt plate 1331 is adjusted by moving the second shunt plate 1332, so as to adjust the height of the shunt plate 133 to adapt to different gas flow, so that the gas distributor can distribute different gas flow, and the distribution uniformity of the gas distributor is improved.

[0054] In some embodiments, the first shunt plate 1331 and the second shunt plate 1332 are both arc-shaped plates, the first shunt plate 1331 is arranged concentrically with the second shunt plate 1332, the first shunt plate 1331 and the second shunt plate 1332 have the same curvature, and the radius of the second shunt plate 1332 is smaller than the radius of the first shunt plate 1331.

[0055] The embodiment sets the first shunt plate 1331 and the second shunt plate 1332 as arc-shaped plates, and arranges the first shunt plate 1331 and the second shunt plate 1332 concentrically, so that when the second shunt plate 1332 is in the retracted position, the second shunt plate 1332 is located on the inner side of the first shunt plate 1331, reducing the influence of the second shunt plate 1332 on the gas, and the arc-shaped plate can more evenly distribute the gas flow, improving the shunting effect of the shunt plate 133.

[0056] For example, the curvature of the first shunt plate 1331 and the second shunt plate 1332 is 90°, and the arc-shaped arrangement can reduce the gas phase resistance.

[0057] For example, when the second shunt plate 1332 is in the retracted position, the second shunt plate 1332 is stacked on the inner side of the first shunt plate 1331, that is, the side of the second shunt plate 1332 away from the shunt.

[0058] For example, the opening of the shunt plate 133 is away from the direction of the gas inlet 14, so that the gas is dispersed through the arc surface of the shunt plate 133, improving the dispersion efficiency of the gas.

[0059] In some embodiments, the height of the first shunt plate 1331 in each shunt plate 133 gradually decreases in the second direction away from the gas inlet 14, and the height of the first shunt plate 1331 in each shunt plate 133 is greater than or equal to the height of the second shunt plate 1332.

[0060] Specifically, as Figure 1As shown, each of the flow distribution plates 133 includes a first flow distribution plate 1331 and a second flow distribution plate 1332, and a plurality of flow distribution plates 133 arranged in the front-rear direction form a group of flow distribution plates 133, that is, each group of flow distribution plates 133 includes a plurality of first flow distribution plates 1331 and a plurality of second flow distribution plates 1332, the plurality of first flow distribution plates 1331 and the plurality of second flow distribution plates 1332 are arranged one-to-one, and the height of the plurality of first flow distribution plates 1331 gradually decreases from front to back, and correspondingly, the height of the plurality of second flow distribution plates 1332 also gradually decreases from front to back, so that the minimum height of the flow distribution plate 133 is the height of the first flow distribution plate 1331, and the maximum height is the sum of the heights of the first flow distribution plate 1331 and the second flow distribution plate 1332.

[0061] In the embodiment, by setting the height of the plurality of first flow distribution plates 1331 in each group of flow distribution plates 133 to be different, the height of the plurality of first flow distribution plates 1331 in each group of flow distribution plates 133 gradually decreases from front to back, which can better adapt to the gradually decreasing gas flow from front to back, thereby improving the uniformity of the gas distribution of the flow distribution plate 133.

[0062] In some embodiments, the top plate 12 includes a plurality of guide plates 121, the plurality of guide plates 121 are arranged in the second direction, and the plurality of guide plates 121 are arranged one-to-one with the plurality of flow distribution plates 133 in each group of flow distribution plates 133.

[0063] Specifically, as shown, Figure 1 The guide plates 121 are arranged in the front-rear direction, and the lower ends of the guide plates 121 are connected to the upper ends of the plurality of flow distribution plates 133 in the plurality of groups of flow distribution plates 133, and through the arrangement of the plurality of guide plates 121, the connection of the plurality of flow distribution plates 133 is realized, and the structural stability of the gas distributor is improved.

[0064] For example, the guide plates 121 are arranged obliquely, and the side of the guide plates 121 away from the gas inlet 14 is chamfered to form an arc shape, which facilitates the flow guiding of the gas. Alternatively, the guide plates 121 are also provided as arc-shaped plates, the openings of the guide plates 121 are arranged towards the direction of the gas inlet 14, and the curvature of the guide plates 121 is set to 90°, thereby reducing the resistance of the gas phase.

[0065] Further, in the embodiment, the gas entering the gas distributor is divided into three parts in the process of flowing backward along the front-rear direction, the first part flows upward from the gap between the adjacent two top plates 12, the second part includes flowing leftward from the gap between the adjacent two flow distribution plates 133 in the second flow distribution plate group 1312 and flowing rightward from the gap between the adjacent two flow distribution plates 133 in the third flow distribution plate group, and the third part includes flowing leftward from the gap between the adjacent two flow distribution plates 133 in the first flow distribution plate group 1311 and flowing rightward from the gap between the adjacent two flow distribution plates 133 in the fourth flow distribution plate group, the gas is dispersed multiple times by the multiple flow distribution plate groups, and the distribution effect of the gas distributor is improved.

[0066] In some embodiments, the gas distributor further comprises a connecting plate 15 extending along the second direction, one end of the connecting plate 15 is connected to the multiple flow distribution plates 133 in each flow distribution plate group, and the other end of the connecting plate 15 is connected to the guide plate 121.

[0067] Specifically, as shown in Figure 1 the connecting plate 15 extends along the front-rear direction, the number of the connecting plate 15 is multiple, the multiple connecting plates 15 are arranged one by one corresponding to the multiple flow distribution plate groups, the front end of the connecting plate 15 is connected to the flow distribution plate 133 located at the most front side in the flow distribution plate group, the rear end of the connecting plate 15 is connected to the flow distribution plate 133 located at the most rear side in the flow distribution plate group, and the lower middle part of the connecting plate 15 is connected to the flow distribution plate 133 located between the flow distribution plate 133 at the most front side and the flow distribution plate 133 at the most rear side in the flow distribution plate group.

[0068] In the embodiment, the multiple connecting plates 15 are arranged, and the connecting plate 15 is connected to the multiple flow distribution plates 133 in each flow distribution plate group, which facilitates the connection between the flow distribution plate 133 and the top plate 12 and improves the structural stability of the multiple flow distribution plates 133.

[0069] In some embodiments, the gas distributor further comprises a flow uniformizing plate 2, the flow uniformizing plate 2 and the distribution assembly 1 are arranged in the up-down direction and are spaced apart, the flow uniformizing plate 2 is located downstream of the distribution assembly 1 in the flow direction of the gas flow, and the flow uniformizing plate 2 is provided with multiple through holes 21 penetrating the flow uniformizing plate 2 along the up-down direction.

[0070] Specifically, as shown in Figure 4 the flow uniformizing plate 2 is connected to the inner wall surface of the absorption tower, the flow uniformizing plate 2 is arranged above the distribution assembly 1, the flow uniformizing plate 2 is uniformly provided with the multiple through holes 21 penetrating the flow uniformizing plate 2 along the up-down direction, which facilitates the upward flow of the gas from the downward direction and improves the uniformity of the gas distribution.
