Jiangsu Lingyu generator Co., Ltd. has obtained a patent for a noise elimination device for the exhaust system of a generator.

Jiangsu Lingyu generator Co., Ltd. has obtained a patent for a noise elimination device for the exhaust system of a generator. This utility model provides a noise elimination device for the exhaust system of a generator, comprising an installation box. The inner wall of the installation box is provided with an adsorption component, which includes a frame plate. A sound-absorbing plate is provided below the frame plate. An expansion tube is fixedly connected to the right side of the installation box, and a circular sound-absorbing ring is provided inside the expansion tube. The outer wall of the circular sound-absorbing ring is provided with a stepped baffle. Compared with the prior art, this utility model has the following beneficial effects: by connecting the installation box and the adsorption component for use, the internal noise enters the interior of the installation box during operation, causing the internal noise to enter the interior of the installation box. The groove formed by the adsorption component is received by the internal sound-absorbing panel, The internal noise is reduced, and the generated noise is connected through an enlarged pipe during discharge. The stepped baffles on the inner wall form a sequential grid contact to gradually reduce the contact noise. At the same time, the circular sound-absorbing ring inside is used to absorb and reduce the noise.
