Cigarette Factory Combined Factory Noise Control And Research

With the introduction of high-speed equipment factory,workshop construction scales,factory noise pollution becomes more and more serious.The noise in the workshop affects the hearing organ,physiology and psychology of the workers.The noise outside the workshop has a great influence on the life and work of the nearby residents.Only by reducing the influence of noise on residents living nearby,can make people healthy life,carry out the factory noise control is very necessary.Subject from the commissioned projects of enterprises,the joint workshop of factory noise on governance,firstly,using modern acoustic test system of air outlet joint workshop of noise test and analysis,obtained the noise source and the acoustic spectral characteristics of critical data,determine the noise of main noise is low frequency characteristics,put forward the difficulties and key techniques of noise the joint workshop of factory management.Through the analysis,the noise attenuation technology,noise,vibration damping,vibration isolation,sound insulation and noise control technology of factory joint workshop has carried on the overall governance,the main noise source is designed to two different types of new muffler muffler governance.Finally,through the study of noise control scheme,the implementation scheme of comprehensive noise control,forming a noise reduction technology combined with factory noise.The three dimensional modeling software Solid Edge,meshing software Hypermesh and simulation software LMS.Virtual.lab are used to design the new muffler,which provides a basis for the design of noise reduction equipment muffler.The noise of exploration and engineering application of the Joint Workshop on this topic in a large domestic cigarette factory,cigarette factory completed the design of combined noise control products,and the success of the product model,through the installation,debugging,the final acceptance by the relevant departments of the environment.After treatment combined operation of the noise reached GB3096-2008?environmental noise standard in urban area? two kinds of noise emission requirements and GB 12348-2008 ? Environmental noise emission standards for industrial enterprises?two kinds of noise emission requirements,ultimately the combined noise operation,effectively solves the influence of factory noise on residents in the vicinity of the joint workshop.At present,the enterprise has planned to apply the control scheme to other industrial noise control.
