Problems solved by technology

[0015] Since the main noise sources in the cement factory area include coal mills, cement mills, raw meal mills, kiln tail fans, kiln head fans, kiln tail electrostatic precipitator fans, packaging, and shipping, etc., there are many sound source equipment in the production plant area. Various types of noise generated during normal operation affect each other and interfere with each other. There is no reasonable plan for the comprehensive control of cement plant boundary noise in the prior art.

Embodiment Construction

[0032] Regarding the reasons for the existing problems in the prior art, the inventor found in the process of research and development that many people think that noise control is very simple, just building walls or making some sound insulation barriers, but noise control in cement plants Among them, through the treatment of the existing technology, in many cases, the effect of noise reduction is obvious, but it still cannot reach the standard, and it is only a few decibels away from the standard value. How to really reach the standard, the existing technology cannot answer.

[0033] For example: According to the standard of Class 2, it is less than or equal to 50dB at night, but most cement plants use electricity at staggered peaks and produce at night. If they want to drop from 55dB to less than 50dB, the cost will be more than the sum of all the previous treatment costs. Therefore, there is a big difference between "reducing a little" and "reducing to the standard". The nois...

Abstract

The invention discloses a method for noise comprehensive treatment of a cement plant. The method includes the specific steps that firstly, a plurality of noise monitoring points are arranged according to a plant boundary range, monitoring time and monitoring conditions are set, and monitoring is conducted to obtain data; secondly, the data obtained through monitoring is compared with a standard value, and monitoring points, where noise exceeds the standard, of sensitive points in the plant boundary and the periphery are analyzed; thirdly, according to analysis in the step 2, the varieties of equipment of noise sound source points in the plant and the varieties of sound sources are determined; fourthly, according to the varieties of the equipment and the sound sources, the equipment is divided into the equipment in a plant building and the equipment in a plant area, the equipment safety production requirements are considered, and comprehensive treatment is carried out according to the varieties of the equipment and the sound sources, so that the frequency spectra of the treated sound sources at a detection point conform to an NR curve; after treatment, the detection value of each sound source at the detection point is smaller than or equal to the standard value which is 3 db. By means of the method, the problem about noise treatment in the cement plant is thoroughly solved.

Description

technical field [0001] The invention relates to a method for controlling noise, in particular to a method for comprehensively controlling noise in a cement plant. Background technique [0002] In the production process of the cement plant, the noise environment is extremely complex. The existing technology adopts the point treatment method when controlling the noise of the cement plant, and for the treatment of a certain point, since the sound source comes from the production equipment, in order not to affect the production equipment, The existing technology mainly uses sound insulation walls or noise reduction enclosures, but the biggest problem caused by this point treatment method is that for a single treatment point, the noise control is qualified, but when the noise of the entire cement plant is monitored, it is found that , Noise control is unqualified. [0003] According to the standards for noise control, the control plan must use the following standards and data as...
