[0035] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0036] like Figures 1 to 4 As shown, according to an embodiment of the present disclosure, a gas distribution device is proposed, including: a cylinder 100, formed with an air inlet 1010; a ventilation part 200, connected to the inner wall of the cylinder 100, the ventilation part 200 is formed with an air passage 2010, the air passage 2010 extends along the circumference of the cylinder 100, and the air inlet 1010 is connected to the air passage 2010; a guide vane 300, connected to the ventilation part 200, the number of the guide vanes 300 is multiple, along the circumference of the cylinder 100, A plurality of guide blades 300 are arranged at intervals, and a guide channel 3010 is formed between adjacent guide blades 300. The wind passage 2010 is located between the guide blades 300 and the inner wall of the cylinder 100, and the guide channel 3010 is connected to the wind passage 2010; a diverter plate 400 is arranged inside the cylinder 100 and connected to the ventilation part 200. The diverter plate 400 is located at the air inlet 1010, and the diverter plate 400 is used to guide the gas to both sides of the air inlet into the wind passage 2010.

[0037] The gas distribution device proposed in the embodiment of the present disclosure includes a cylinder 100, a ventilation part 200, a guide vane 300 and a splitter plate 400; wherein the ventilation part 200 is connected to the inner wall of the cylinder 100 and is located inside the cylinder 100, the ventilation part 200 is formed with an air passage 2010, the air passage 2010 extends along the circumference of the cylinder 100, a plurality of guide vanes 300 are connected to the ventilation part 200, the plurality of guide vanes 300 are arranged at intervals along the circumference of the cylinder 100, and a guide channel 3010 connected to the air passage 2010 is formed between two adjacent guide vanes 300. In actual application, the cylinder 100 is formed with an air inlet 1010, the air passage 2010 is connected to the air inlet 1010, the gas enters from the air inlet 1010, a splitter plate 400 is arranged at the position of the air inlet 1010, the splitter plate 400 is located inside the cylinder 100, and the splitter plate 400 can The gas entering from the air inlet 1010 is guided to both sides and introduced into the air passage 2010. Then, the gas can flow along the conducting direction of the air passage 2010. When passing through the guide channel 3010, part of the gas will enter the guide channel 3010 and flow out from the guide channel 3010. Since the guide channel 3010 is located on the side of the air passage 2010 away from the inner wall of the cylinder 100, the gas flowing out from the guide channel 3010 will flow toward the center of the cylinder 100. Since the guide channel 3010 is arranged at intervals along the circumference of the cylinder 100, the gas entering from the air inlet 1010 will flow from multiple points on the circumference of the cylinder 100 to the center of the cylinder 100 after passing through the gas distribution device, which is conducive to a more uniform distribution of the gas entering the tower, which is conducive to better performance of the tower equipment and can effectively save the operation, maintenance and other related costs of the tower equipment.

[0038] It can be understood that the center of the cylinder 100 mentioned above is the approximate position where the axis of the cylinder 100 is located.

[0039] It can be understood that the guide blade 300 has a certain curvature, and at one end of the guide channel 3010 connected to the wind passage 2010, the transition between the guide channel 3010 and the wind passage 2010 is smooth, and the conducting direction of the guide channel 3010 is close to the conducting direction of the wind passage 2010, or there is a small inclination angle between the conducting direction of the guide channel 3010 and the conducting direction of the wind passage 2010, so that the gas can smoothly enter the guide channel 3010 when it flows from the wind passage 2010 to the guide channel 3010, which is beneficial to reducing the gas pressure drop; at the end of the guide channel 3010 away from the wind passage 2010, the conducting direction of the guide channel 3010 is close to the radial direction of the cylinder 100, so that the guide channel 3010 can guide the gas to the center of the cylinder 100, which is beneficial to more uniform distribution of the gas entering the tower.

[0040] It can be understood that the diverter plate 400 includes a first diverter plate 400 body and a second diverter plate 400 body, wherein one end of the first diverter plate 400 body is connected to the second diverter plate 400 body, and the connection between the first diverter plate 400 body and the second diverter plate 400 body is located at the air inlet 1010, and one end of the first diverter plate 400 body away from the second diverter plate 400 body is connected to the guide vane 300, and one end of the second diverter plate 400 body away from the first diverter plate 400 body is also connected to the guide vane 300, so that the gas entering the air inlet 1010 can be divided into two under the action of the diverter plate 400, and flow to the wind channels 2010 on both sides of the air inlet, and then be guided by the guide vanes 300 and discharged from the guide channels 3010.

[0041] In some examples, such as Figure 4 As shown, the orthographic projection of the air passage 2010 in the axial direction of the cylinder 100 gradually decreases along the direction from the air inlet 1010 to the inner wall of the cylinder 100 directly facing the air inlet 1010.

[0042] In the above technical solution, along the direction from the air inlet 1010 to the inner wall of the cylinder 100 directly facing the air inlet 1010, the cylinder 100 can be divided into two parts along the straight line direction, that is, the air passage 2010 is divided into two parts, and the two parts of the air passage 2010, the air passage 2010 is projected along the axial direction of the cylinder 100 to the plane perpendicular to the axial direction of the cylinder 100, and the projection area of ​​the obtained air passage 2010 gradually decreases along the direction from the air inlet 1010 to the inner wall of the cylinder 100 directly facing the air inlet 1010; reflected in practical applications, the gas entering from the air inlet 1010 is divided into two parts in the diversion. Under the action of the plate 400, the gas will flow to the two parts of the air passage 2010. The internal space of each part of the air passage 2010 will gradually shrink along the flow direction of the gas. As the gas flows, part of the gas will be discharged from the guide channel 3010, and the gas pressure will be reduced. The shrinkage of the air passage 2010 will help to increase the gas pressure, thereby suppressing the pressure drop of the gas, and ensuring that the gas pressure flowing into the guide channel 3010 from various positions in the air passage 2010 is relatively balanced, thereby helping to make the gas entering the tower through the guide channel 3010 more evenly distributed.

[0043] In some examples, such as Figures 1 to 3As shown, the ventilation part 200 includes: a first plate body 210, which is connected to the inner wall of the cylinder body 100; a second plate body 220, which is connected to the inner wall of the cylinder body 100, and an air passage 2010 is formed between the first plate body 210 and the second plate body 220; a third plate body 230, which is connected to the inner wall of the cylinder body 100, and along the axial direction of the cylinder body 100, the third plate body 230 is located between the first plate body 210 and the second plate body 220, and the third plate body 230 divides the air passage 2010 into a first air passage section and a second air passage section; wherein, a guide vane 300 and a diverter plate 400 are connected between the first plate body 210 and the third plate body 230, and a guide vane 300 and a diverter plate 400 are also connected between the second plate body 220 and the third plate body 230.

[0044] In the above technical solution, the ventilation part 200 includes a first plate body 210, a second plate body 220 and a third plate body 230, and the first plate body 210, the second plate body 220 and the third plate body 230 are all connected to the inner wall of the cylinder body 100, and along the axial direction of the cylinder body 100, the first plate body 210, the third plate body 230 and the second plate body 220 are arranged at intervals, and the third plate body 230 is located between the first plate body 210 and the second plate body 220, and the air passage 2010 is formed between the first plate body 210 and the second plate body 220, and the third plate body 230 divides the air passage 2010 into a first air passage section and a second air passage section, and at the same time, a guide vane 300 and a diverter plate 400 are connected between the first plate body 210 and the third plate body 230, and the second plate body 230 is connected to the third plate body 230. A guide blade 300 and a diverter plate 400 are also connected between the body 220 and the third plate body 230, that is, the first wind section and the second wind section are both arranged in a plurality of guide channels 3010 connected thereto; in actual application, the third plate body 230 can divide the air inlet 1010 into two parts, an upper part and an lower part, so that a part of the gas entering from the air inlet 1010 enters the first wind section and a part enters the second wind section, and at the same time, the diverter plate 400 can also divide the gas into two left and right parts, both of which have the first wind section and the second wind section, so that the gas entering from the air inlet can be divided into four parts through the third plate body 230 and the diverter plate 400, and then discharged through the guide channel 3010, which can further make the gas entering the tower more evenly distributed.

[0045] In some examples, such as Figures 1 to 3 As shown, the guide channels 3010 located on both sides of the third plate body 230 are arranged in a staggered manner.

[0046] In the above technical solution, on both sides of the third plate 230, the guide channels 3010 located in the first wind pass section and the guide channels 3010 located in the second wind pass section are arranged alternately, which conforms to the actual flow law of the gas, making the speed of the outlets of the guide blades 300 of each part more uniform, and at the same time is beneficial to improve the mixing degree of the upper and lower parts of the gas, and can also reduce vortex and backflow phenomena.

[0047] In some examples, such as Figure 4 As shown, along the radial direction of the cylinder 100, the air outlets of the guide channel 3010 correspond to each other.

[0048] In the above technical scheme, since the air passage 2010 is arranged along the circumference of the cylinder 100, the air outlet of the guide channel 3010 is also arranged along the circumference of the cylinder 100. At the same time, along the radial direction of the cylinder 100, the air outlets of the guide channel 3010 correspond to each other, that is, the directions of gas outflow correspond to each other, which is conducive to forming a stable flow field and reducing the randomness of gas flow. The airflow can collide and mix along the radial direction, reduce energy dissipation, further reduce the pressure drop of the device, and effectively save equipment operating costs.

[0049] In some examples, such as Figure 1 As shown, Figures 1 to 3 As shown, the third plate 230 passes through the axis of the air inlet 1010 .

[0050] In the above technical solution, the third plate 230 divides the air inlet 1010 into two halves, which is beneficial for the gas entering from the air inlet 1010 to flow evenly to the first air flow section and the second air flow section, thereby balancing the gas content entering the first air flow section and the second air flow section, and facilitating uniform distribution of the gas.

[0051] In some examples, such as Figures 1 to 3 As shown, the distance from the axis of the air inlet 1010 to the first plate 210 is equal to the distance from the axis of the air inlet 1010 to the second plate 220 .

[0052] In the above technical solution, the air inlet 1010 is located in the middle of the first plate body 210 and the second plate body 220, and the distance between the third plate body 230 and the first plate body 210 is equal to the distance between the third plate body 230 and the second plate body 220, that is, the first air flow section and the second air flow section are symmetrical about the third plate body 230, which is beneficial to ensure that the gas pressure entering the first air flow section and the second air flow section from the air inlet 1010 is more balanced, which is further beneficial to the uniform distribution of the gas.

[0053] In some examples, along the axial direction of the cylinder 100 , the first plate 210 and the second plate 220 are arranged in parallel, and the distance between the first plate 210 and the second plate 220 is 1.6 times the inner diameter of the air inlet 1010 .

[0054] In the above technical solution, the distance between the first plate 210 and the second plate 220 is 1.6 times the inner diameter of the air inlet 1010, which can ensure that the air flow velocity does not fluctuate too much after the gas enters the tower body from the inlet, thereby ensuring the uniform distribution of the air flow after the gas enters the tower.

[0055] In some examples, the first plate 210 , the second plate 220 , and the third plate 230 have the same shape, and along the radial direction of the cylinder 100 , the width of the first plate 210 is 0.05 times to 0.1 times the inner diameter of the cylinder 100 .

[0056] In the above technical solution, since appropriately expanding the gas flow channel can reduce the gas flow rate entering the tower and reduce the gas pressure loss, it can also promote the uniform distribution of the gas flow after the gas enters the tower. The width of the first plate 210, the second plate 220 and the third plate 230 is 0.05 times to 0.1 times the inner diameter of the cylinder 100, which can ensure that the gas has a sufficient flow rate after entering the tower and avoid excessive gas pressure loss.

[0057] In some examples, such as Figures 1 to 3 As shown, it also includes: a reinforcing rib plate 500, which is arranged on the ventilation part 200 and connected to the cylinder 100. Along the axial direction of the cylinder 100, the reinforcing rib plate 500 is located on both sides of the air passage 2010.

[0058] In the above technical solution, the gas distribution device also includes a reinforcing rib 500, which is arranged on the ventilation part 200 and connected to the cylinder 100, which is beneficial to improve the connection strength between the ventilation part 200 and the cylinder 100. At the same time, the reinforcing rib 500 is located on both sides of the air passage 2010 to avoid the reinforcing rib 500 from affecting the gas flow in the air passage 2010.

[0059] It can be understood that a plurality of reinforcing rib plates 500 may be provided, and the plurality of reinforcing rib plates 500 are arranged at intervals along the circumference of the cylinder 100 .
