Description
Technical field
The present invention relates to a kind of silencing means, more particularly to a kind of horizontal silencing means.
Background technology
Noise pollution is the generally acknowledged environmental problem in the world today.From 1950s, with industrial fast development, noise pollution is increasingly serious.Particularly in today of industrialization competition, there is each noise like in succession in industrial department such as power station, chemical industry, metallurgy, communications and transportation etc., endangers the health of people, influences operating efficiency, almost everybody is influenceed by noise.Silencer is the important channel for controlling Industrial Equipment Noise.
Silencer can be divided into dissipative muffler, reactive muffler and Small-Bore Jet Noise Muffler according to its noise-cancelling theory.Dissipative muffler is a kind of absorption-type silencer, and it is when being propagated using sound wave in porous sound-absorbing material, to be dissipated acoustic energy is converted into heat energy because rubbing, so as to reach the purpose of noise elimination.It is, in general, that dissipative muffler has good medium-high frequency acoustic attenuation performance, it is poor to low frequency acoustic attenuation performance.Reactive muffler is different from dissipative muffler, it is without using sound-absorbing material, but rely on mutation or connection resonant cavity of pipeline section etc. to cause the change of impedance during acoustic propagation and produce the reflection, interference and resonance sound-absorbing of acoustic energy to reduce acoustic energy of the silencer to external radiation, reach noise elimination purpose.
A variety of silencers are currently there are, but the complicated of most of silencers, cost are higher, soundproof effect is poor.
The content of the invention
It is an object of the invention to provide a kind of horizontal silencing means, simple and reasonable, soundproof effect is preferable, cost of manufacture is relatively low, can be widely applied to every field.
The purpose of the present invention is achieved through the following technical solutions：
A kind of horizontal silencing means, including cylinder, support frame, air inlet pipe, blast pipe, the cylinder are supported by bottom left and right sides support frame, the cylinder left end device air inlet pipe, right-hand member device blast pipe；Part device dissipates tone chamber in the inner barrel left end device noise reduction pressure-bearing room, the noise reduction pressure-bearing room；Soundboard is hindered on the noise reduction pressure-bearing room right-hand unit polylith and is arranged at intervals with hindering soundboard, the upper resistance soundboard under polylith with lower resistance soundboard；The upper resistance soundboard and lower resistance soundboard right-hand unit multiple layer sound suction cotton layer；The acoustical cotton layer right-hand unit noise reduction partial device.
Multiple hollow outs mouthful are set on each wall of the scattered tone chamber.
Device insulation material layer in the noise reduction pressure-bearing chamber interior walls, noise reduction pressure-bearing ceiling end left end, bottom surface left end one blow vent of each device.
The upper resistance soundboard is all elastic caoutchouc baffle plate with lower resistance soundboard.
The noise reduction partial device is separately interted by three pieces of perpendicular acoustical panels with four blocks of horizontal partial plates to be spliced, and the perpendicular acoustical panel is with all setting multiple hollow outs mouthful on horizontal partial plate, the perpendicular acoustical panel and horizontal partial plate are all wood based panel.
Device acoustical cotton layer on the cylinder inboard wall.
A kind of horizontal silencing means of the present invention, in use, noise gas is entered to inside scattered tone chamber from air inlet pipe first first, multiple hollow outs mouthful are set on each wall for dissipating tone chamber, effectively combine the advantage of aperture noise reduction, differentiation processing is carried out to noise, then noise enters to the every portion in noise reduction pressure-bearing room, device insulation material layer in noise reduction pressure-bearing chamber interior walls, effectively combine the advantage of resistant noise-reducing device, absorb after partial noise, noise enters to inner barrel by blow vent, then through upper resistance soundboard, the lower resistance resistive noise reduction of soundboard, again through multiple layer sound suction cotton layer sound-absorbing, finally again through after the noise reduction partial device processing for erecting acoustical panel and horizontal partial plate interval, from blast pipe discharge, the final noise for causing discharge does not influence the life of people completely, compound national regulation noise emission standards.
Beneficial effects of the present invention：A kind of horizontal silencing means of the present invention, be
Resistance, resistive, micropore jet type silencer advantage is combined to be made,
Simple and reasonable, soundproof effect is preferable, cost of manufacture is relatively low；The present invention
All kinds of station boilers, Industrial Boiler, reheater, superheater, the exhaust noise for starting separator and safety valve etc. suitable for reducing various parameters, it is also applied for reducing discharge or the emptying noise of the process gas of the equipment such as pressurized tank, injector, the chemical reactors of industrial department such as chemical industry, metallurgy, communications and transportation and container, could be applicable to reduce the washing pipe noise of each industrial department and R＆D institution's pipeline.
