Noise comprehensive treatment system for gas-driven generator set and distributed energy station

Abstract

The invention provides a noise comprehensive treatment system for a gas-driven generator set and a distributed energy station. The noise comprehensive treatment system comprises a sound source monitoring system and noise comprehensive treatment equipment; the sound source monitoring system collects the information of sound source videos and noise grades; the combined type sound-absorption wall bodies of the noise comprehensive treatment equipment can be combined into a room body, and the sound source is integrally coated; a pipeline sound-absorption sleeve is arranged on a wall penetrating pipeline in a sleeving mode, the wall penetrating pipeline can be prevented from being in contact with the wall body, the noise is reduced, and meanwhile, the situation that the noise is spread through the wall body is reduced; and a damping composite partition plate type sound absorber is adopted, the double-layer characteristics of a folded plate type silencer and a damping silencer are achieved, and the exhaust noise can be greatly reduced. According to the noise comprehensive treatment system, sound source monitoring and noise evaluation can be facilitated, intelligent setting can be carriedout according to the type of the sound source, the noise reduction amount reaches more than 30 dB (A), noise pollution can be greatly reduced, and the health, lives and working states of surrounding people can be improved.

Description

technical field [0001] The invention relates to the field of noise control, in particular to a comprehensive noise control system for a gas-fired unit and a distributed energy station. Background technique [0002] According to relevant report statistics, since the 21st century, the "black area" (serious interference area with ambient noise greater than 65dB(A)) in most cities has not increased, but the "gray area" (environmental noise between 55-65dB(A) The moderate interference area between them) has increased significantly, which shows that the problem of environmental noise pollution has increasingly become one of the important issues affecting the healthy development and life and work of urban people. [0003] Among the various sources of noise affecting the urban environment, social life noise accounts for 47%, industrial noise accounts for 8-10%, construction site noise accounts for about 5%, and traffic noise accounts for about 30%. [0004] Regarding industrial noi...

Problems solved by technology

[0004] Regarding industrial noise, in recent years, the Chinese government has vigorously encouraged the development of distributed energy generation technology fueled by natural gas, but there is a problem of noise pollution that cannot be ignored in gas-fired distributed energy projects. Compared with traditional power stations, gas-fired distributed energy The capacity of the unit is relatively small, and it is generally close to the client. Taking a high-power natural gas internal combustion engine generator set as an example, when it is running at full load, the noise generated usually reaches 90-120dB(A). The treatment will cause huge industrial noise pollution to the surrounding environment and seriously affect the health, living and working conditions of the surrounding people.
