国内现有的空压机组的消声措施已可把空气动力噪声有效地降到70dB(A)以下,但对降低机组的机械噪声却无能为力。因此,空压站的操作人员大都处在90dB(A)左右的噪声环境中。根据“工业企业噪声卫生标准”和“压缩空气站设计规范”(TJ29-78)的有关规定,为了保护工人的健康,尽可能设置隔声值班室,使工人在进行经常性的操作、检查、维护、保养等工作之余,有一个较为安静的环境,及减少超标噪声的暴露时间。据此,我们在重庆特殊钢厂新、老空压站的噪声综合治理项目中,设计了两个隔声值班室。 1.隔声值班室的大小和位置从经济观点和机组日常运行工作的实际需要出发,尚无必要对机组进行遥控、遥测。因此,值班
The noise reduction measures of the existing domestic air compressor units have effectively reduced the aerodynamic noise to less than 70dB (A), but can not reduce the mechanical noise of the aircrew. Therefore, the air compressor station operators are mostly in the 90dB (A) around the noise environment. According to the relevant provisions of “Industrial Enterprise Noise Standards for Noise” and “Design Code for Compressed Air Station” (TJ29-78), in order to protect the health of workers, sound insulation duty rooms shall be set up as far as possible to enable workers to carry out regular operation, inspection, Maintenance, maintenance and other spare time, there is a more quiet environment, and reduce the exposure of excessive noise. Accordingly, we have designed two noise-proof duty rooms in the noise comprehensive treatment project of new and old compressed air stations in Chongqing Special Steel Plant. 1. Soundproof duty room size and location From the economic point of view and the daily operation of the actual needs of the crew, there is no need for remote control units, telemetry. So on duty
