FIELD: mechanical engineering. ^ SUBSTANCE: invention can be used in compressor stations. Proposed silencer contains housing of round or square cross section with outer size "c" and inner size "b", intake member in form of tube with at least three holes in lower part and exhaust member made in form of louvers with size "d" in upper part of housing. Layer of noise absorber is fastened to inner surface of housing cover. At least grills with filled layer of noise-absorbing material are placed on rolled bearing structure inside housing. Filled layer has thickness "a" being made of crushed stone. Distance between upper layer of noise-absorbing material and grill of other layer is equal to "a" also. Ratios of above-indicated sizes lie in intervals of a/b=0.1-0.3 and d/b-0.4-0.7. ^ EFFECT: improved efficiency of noise damping. ^ 2 cl, 1 dwg |
