Description

Array type ventilation silencer suitable for power plant and cement plant
Technical Field
The array type ventilation silencer relates to the noise control field of large industrial enterprises such as electric power, steel, mines, chemical industry and the like, in particular to the array type ventilation silencer suitable for power plants and cement plants.
Background
Along with the continuous development of industry, the pollution of noise is also serious, and even the sleeping, working and learning of people are directly influenced, so that the enterprise is highly valued, and effective measures are taken for treatment.
At present, the industrial enterprises perform noise reduction treatment on various noises in the production process so as to improve the factory acoustic environment, meet the professional health standard or improve the production and living environments of workers. Especially, for some production workshops or occasions with high noise emission, scientific and reasonable noise reduction measures can greatly improve the current situation of noise pollution and reduce the harm caused by noise to people. The air output of industrial fan equipment of many enterprises is large, the noise is high, the section of the air outlet is large, the noise treatment difficulty is high, and the construction period is long; an array type ventilation silencer suitable for a power plant and a cement plant is designed mainly aiming at the difficulties.
Disclosure of Invention
The utility model provides an array type ventilation silencer suitable for power plants and cement plants, which aims to achieve better sound absorption, insulation and ventilation effects. The technical scheme is as follows: the silencer comprises a sound insulation plate, sound insulation cotton, a framework, a sound absorption plate, a steel structure framework, a sound absorption column supporting beam, a sound absorption column sound absorption plate, sound absorption cotton, guide caps, connecting bolts and flanges.
As an improvement, the silencing post modules are in cylindrical shape and distributed in an array mode, when sound waves pass through the silencer, the silencing posts distributed in the array mode play a role in absorbing sound, and the sound insulation shell blocks the sound waves radiated to the periphery, so that ventilation is guaranteed, and meanwhile, the silencing effect is achieved.
As an improvement, the diversion caps at the two sides of the silencing post module are hemispherical.
The improved sound insulating shell consists of sound insulating board, sound insulating cotton, skeleton and sound absorbing board.
One side of the array type ventilation silencer suitable for power plants and cement plants is provided with a flange 11 which is connected with an air outlet flange. When sound waves and air flow pass through the air outlet, the sound waves and the air flow pass through a reducing cavity, the cavity space is changed from small to large, the flow speed is reduced, the pressure loss is reduced, the pressure of a system fan is reduced, the sound waves and the air flow are refracted to different directions through hemispherical silencing column diversion caps 9 arranged in an array manner, and the uniformly distributed silencing column modules absorb the refracted sound waves, so that the overall silencing performance of the array type silencer is improved; the silencing column module and the silencing column module, and the gap between the silencing column module and the shell form a silencing channel of the silencer together, so that energy consumption is reduced when sound waves and air pass through, the silencing column module and the sound insulation shell all play a role in sound absorption and insulation, the noise quantity of an air outlet is reduced, and silencing is achieved. The inner layer acoustic board 4 and the middle layer acoustic board 1 of the acoustic shell effectively block sound waves radiated to the periphery when the middle layer acoustic board absorbs sound through the acoustic cotton 2, and good sound absorption and insulation effects are achieved. The four sides of the sound-absorbing column module are sound-absorbing boards 7, and the sound-absorbing cotton 8 is filled in the sound-absorbing column module. The sound absorption area is increased. Compared with the same volume of the sheet type silencer, the array type silencer has larger sound absorption surface area, higher sound absorption capacity and better noise reduction effect.
The array type ventilation silencer is suitable for a power plant and a cement plant, is decomposed into a single silencing column module and other parts in the manufacturing process, saves space during transportation, and is convenient to transport and install. And the transportation cost is saved. The sound insulation shell, the steel structure framework 5, the silencing post module and the sound insulation shell are manufactured in a factory, transported to the site and assembled on the site. The sound insulation shell is formed by assembling several parts and is fixed on the steel structure frame 5, the diversion caps 9 at the two ends of the silencing post module are connected with the supporting cross beam 6 through bolts, and the supporting cross beam 6 is fixedly bolted with the steel structure frame 5.
The method has the following technical characteristics:
1. the sound insulation effect is good: when the sound wave passes through the pipeline opening and is diffused in a variable diameter mode and then passes through the circular silencing column diversion caps arranged in an array mode, the sound wave is refracted to different directions, and the sound wave is absorbed through the silencing column module, so that the overall silencing performance of the array type silencer is improved.
2. The transportation is convenient: the array type ventilation silencer is suitable for ventilation silencing with large size and large air quantity. The silencing column is in modular design, is assembled through on-site bolting, can be detached at any time to be replaced or cleaned, and is convenient to transport and install. The method is widely suitable for noise control of large industrial enterprises such as power plants, steel plants, cement plants and the like.
