specific Embodiment 1

[0024] refer to figure 1 , the muffler of the present invention includes a main body 1 and a cover body 2, and a sound-absorbing layer 4 is provided on the inner cavity walls of the main body 1 and the cover body 2; The cover body 2 is fixedly connected; the side wall of the main body 1 is provided with a pipe connection port 7, the cover body 2 is provided with four exhaust pipes 8 whose cross-section is smaller than that of the main body 1, and the cover plate 6 is provided with a guide that communicates with the inner cavity of the cover body 2. Flow tube 9.

[0025] In this example:

[0026] The bottom surface of the main body 1 is further provided with a base 3 , and the base 3 is fixedly connected to the main body 1 through a bottom plate 5 , and a drain pipe 10 communicating with the inner cavity of the main body 1 is arranged in the bottom plate 5 . The base 3 consists of three or four supporting feet 31 made of angle steel. The exhaust pipe 8 is composed of four pi...

specific Embodiment 2

[0034] The feature of this embodiment is that the main body 1 and the cover body 2 are integrally formed, and the inner cavity of the main body 1 and the inner cavity of the cover body 2 are separated by the cover plate 6 . The rest are the same as in specific embodiment 1.

specific Embodiment 3

[0035] The features of this embodiment are: the inner cavity wall of the main body 1 is provided with a sound-absorbing layer 4; the main body 1 and the cover body 2 can be integrally formed, and the inner cavity of the main body 1 and the inner cavity of the cover body 2 are separated by the cover plate 6 , it can also be a separate structure, and the main body 1 and the cover body 2 are fixedly connected through the cover body 6 . The rest are the same as in specific embodiment 1.

[0036] Other examples:

[0037] The best embodiment of the present invention is to use angle steel as the base 4, so as to realize the most convenient fixed connection with the roof and save costs. The number of exhaust pipes 8 can be two, three, five, six, eight or ten; the sound absorbing layer 4 can be made of soft thermal insulation material. The drain pipe 10 is provided with a water valve.

Abstract

The invention relates to a method to muffle the exhaust and the blow-off pipelines of power plants as well as a novel environment-friendly muffler. 1) A novel muffler is used to deaden the noise of the waste gas or water vapor discharged from the exhaust and blow-off pipelines of a power plant, and then the waste gas and water vapor are discharged, and thereby, silencing is achieved; 2) the novel environment-friendly muffler comprises a main body (1) and a cover body (2), a noise-absorbing layer (4) is arranged on the intracavity wall of the main body (1) and the intracavity wall of the cover body (2); a pipeline connecting opening (7) is arranged on the side wall or the bottom surface of the main body (1), a plurality of exhaust pipes (8) with a cross section smaller than the cross section of the main body (1), and a flow guide pipe (9) communicating with the cover body (2) is arranged in the cover plate (6). The invention has the advantages of simple structure, utilization of local materials, low cost, easy assembly and disassembly and remarkable noise muffling effect. The invention can be extensively applied to muffling the exhaust and blow-off pipelines of rotary machines in power plants.

Description

technical field [0001] The invention relates to a noise reduction method for an exhaust / exhaust steam pipe of a power plant and a novel environmental protection muffler. It belongs to the technical field of noise reduction of power plants. Background technique [0002] In the prior art, part of the exhaust (steam) pipelines of power plants need to slowly discharge water vapor and air (exhaust gas), because the discharge speed is relatively slow and the noise generated is not particularly large, and the existing conventional noise reduction equipment has a structure. Complex and high-cost defects, therefore, in the design specification, there is no requirement to install noise reduction equipment for this type of pipeline, the purpose of which is to reduce the one-time investment. However, when the equipment is a rotating machine, these pipes will generate noise when they discharge water vapor and air (exhaust gas), and cause noise interference to the surrounding area, formi...
