Air intake and noise reduction system

Abstract

The invention discloses an air intake and noise reduction system, which is used for providing air for burning and cooling for a generator set (comprising engines and generators) in a sealed space. The air intake and noise reduction system comprises an air intake path which is arranged on bodies at two sides of the generator set, and a noise reduction grid is arranged in the air intake path. The air intake and noise reduction system is characterized in that the air intake and noise reduction grid is provided with a first horizontal section and a second horizontal section, wherein an inclined section is connected between the first horizontal section and the second horizontal section, and the noise reduction grid causes the air intake path to form a plurality of paths. Compared with the prior art, the invention has simple structure and can improve noise reduction effect, noise in the compartment is reduced to about 65 decibels (the noise value on the position far away from the air intake port for 1m) from original 100 decibels so as to totally conform to the environment protection requirements on equipment noise, and the purpose of improving working environment is realized.

Description

technical field The invention belongs to the technical field of power equipment, and in particular relates to an intake air noise reduction system that provides air for combustion and cooling to a generating set (including an engine and a generator) in a confined space. Background technique In the known technology, diesel or non-diesel generator set is used as a power source for maintenance or power distribution in the field without electricity and when the power is cut off. When the generator set is working, the noise is particularly loud and affects the surrounding environment. In order to reduce the noise, it Set up in a compartment or in a separate room such as a power cart. Since the box body or room is also provided with an air intake channel for combustion and cooling air, the noise of the generator set will also transmit noise through the air intake channel. Most of the existing air intake and noise reduction structures are provided with a plurality of oblique air i...

AI Technical Summary

Problems solved by technology

Most of the existing air intake and noise reduction structures are provided with a plurality of oblique air intake and noise reduction grids at the air inlet. The space is still directly connected to the outside world through the air intake noise reduction grid or bypass, so the sound insulation effect is not ideal. The wind resistance and large flow are not ideal, and the noise has a significant impact on the outside world.
