[0003] In view of the above problems of the prior art, the utility model provides a device for improving the noise of combustor, which can reduce the noise of the air inlet of combustor and solve the above problems.

[0004] In order to achieve the above purpose, the utility model adopts the technical scheme of a device for improving the noise of combustor, comprising: a head and a separation vane ring arranged on the head, wherein the separation vane ring is formed by a plurality of arc-shaped separation vanes arranged in a ring shape.

[0005] Further, the head is a bowl-shaped head, and the bottom surface of the bowl-shaped head is a spherical surface.

[0006] Further, the circular separation vane ring is arranged at the center of the bottom surface of the head.

[0007] Further, the separation vane ring is provided with a plurality of groups, and the plurality of groups of separation vane rings share a center.

[0008] Further, the adjacent separation vane rings are arranged in a staggered manner.

[0009] Further, the curvature of the arc-shaped separation vanes in the separation vane ring is the same.

[0010] Further, the separation vane ring is provided with two groups, the first group of separation vane rings is arranged at 1 / 2 of the head, and the second group of separation vane rings is arranged at 1 / 4 of the head.

[0011] Further, each group of separation vane rings is provided with six arc-shaped separation vanes, and the curvature of the arc-shaped separation vanes in each group of separation vane rings is 50°, and the interval is 12°.

[0012] Further, the staggered angle of the first group of separation vane rings and the second group of separation vane rings is 30°.

[0013] The beneficial effect of the utility model is that a sound insulation zone is established by arranging an isolation blade ring inside the head, so that the burner noise sound waves are transmitted while the noise sound wave transmission distance is reduced through the sound insulation zone, and the sound wave transmission path can also be changed, thereby ultimately achieving the purpose of reducing noise.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention pertains. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0021] like Figures 1-3 As shown, a device for improving burner noise includes: a head 1 and an isolation blade ring 2 arranged on the head 1, wherein the isolation blade ring 2 is composed of a plurality of arc-shaped isolation blades 21 distributed in a ring-shaped manner.

[0022] like Figure 3 As shown, the head 1 is a bowl-shaped head 1 , the bottom surface of the bowl-shaped head 1 is a spherical surface, and the circular isolation blade ring 2 is set at the center of the bottom surface of the head 1 .

[0023] like Figures 1-2 As shown, there are multiple groups of isolation leaf rings 2, and the multiple groups of isolation leaf rings 2 share a common center. For example, if there are 2, 3, 4, 5 or 6 groups of isolation leaf rings 2, the isolation leaf rings 2 in the several groups all share the same point as the center.

[0024] like Figures 1-2As shown, multiple groups of isolation leaf rings 2 are distributed at equal intervals. This distribution method can be selected as needed and is only applicable when there are more than or equal to 3 groups of isolation leaf rings 2.

[0025] like Figures 1-2 As shown, the adjacent isolation blade rings 2 are staggered in spacing, which serves to establish a sound insulation zone inside the head 1, change the direction and path of sound wave transmission, and help the head 1 and the internal sound insulation zone absorb noise, thereby reducing the spread of noise.

[0026] like Figures 1-2 As shown, the arc-shaped isolation blades 21 in the isolation blade ring 2 have the same curvature.

[0027] like Figures 1-3 As shown, in this example, the isolation blade rings 2 are further provided with two groups, the first group of isolation blade rings 2 is provided at 1 / 2 of the head 1, and the second group of isolation blade rings 2 is provided at 1 / 4 of the head 1.

[0028] Furthermore, in this example, each group of the isolation blade rings 2 is provided with 6 arc-shaped isolation blades 21, such as Figure 4 As shown, the arc angle of the arc-shaped isolation blades 21 in each group of the isolation blade rings 2 is 50°, and the interval is 12°.

[0029] Furthermore, in this example, the first set of isolation blade rings 2 and the second set of isolation blade rings 2 have an interval misalignment angle of 30°, which block each other inside the head 1 and change the direction and path of sound wave transmission, thereby reducing noise.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
