Abstract
The utility model relates to a micropore silencer, which comprises a support and a silencing tube body arranged on the support. Micropores are evenly distributed on the silencing tube body. The micropores are circular. The micropores are arranged on the silencing tube body in the shape of a triangle or a quadrate. The micropore silencer is designed by adopting the principle of 'micropore jet' and is produced and inspected according to relevant departmental standard. The utility model has the advantages that the silencing effect is good, and the volume silenced by the silencer for safety valves is 25dB (A) to 28 dB (A); and the volume silenced by the exhaust silencer for superheaters and reheaters is 38 dB (A), the loudness is decreased by 80 percent, the silencing tube is rustproof because the silencing tube is made of stainless steel, the steel consumption is small, the service life is long, the installation is convenient, the structure is simple, the volume is small and the weight is light, the exhaust pipe does not bear large external force because of the installation of the silencer, the dismounting and the maintenance are convenient, and the displacement, the jump and the re-seating of the safety valves are not affected.
Description
Technical field
The utility model relates to a kind of silencing apparatus that air power noise is propagated outward of controlling, particularly a kind of tiny hole noise silencer that is used to eliminate the exhaust noise of boiler superheater exhaust, hot gas exhaust again, safety valve or power relief valve.
Background technique
Existing large-scale ventilation noise reducing apparatus generally adopts the resistive sheet silencing apparatus of sound-absorbing material, such silencing apparatus in use for some time, acoustic attenuation performance seriously descends, its reason be the sound-absorbing material that adopts through vapor mixing body certain hour wash away with cavitation after, the surface coated protection material of sound-absorbing material peels off, sound-absorbing material is lost sound absorbing capabilities after absorbing moisture, and the sound-absorbing material of sheet damages easily through contact the back with the long-term vibration of sound wave, reduces acoustically effective.
The model utility content
The purpose of this utility model is the shortcoming at existing silencing apparatus, and the tiny hole noise silencer of a kind of new-type good muffling effect, long service life is provided.
The technical solution of the utility model is: a kind of tiny hole noise silencer, comprise bearing and be arranged at noise reduction cylindrical shell on the bearing, be evenly equipped with micropunch on the described noise reduction cylindrical shell, described micropunch be shaped as circle, the arrangement mode of micropore can form uniform triangle or square on the cylindrical shell.
Preferably: the two ends of described cylindrical shell are provided with upper and lower end socket, and upper cover is provided with hanger.
Preferably: described lower seal head is provided with exhaust steam pipe.
The beneficial effects of the utility model are: the utility model adopts " micropore jet " principle design, and by relevant ministry standard production and check, has following characteristics: good muffling effect, safety valve mufflellr sound-damping qualities 25-28dB (A); Superheater, reheater emptying baffler sound-damping qualities 38dB (A), loudness reduces by 80%, and hush pipe adopts stainless steel to make, and is difficult for getting rusty, steel consumption is few, life-span is long, and is easy for installation, simple in structure, the little body of body is light, make outlet pipe can not bear big external force because of settling baffler, the maintenance of disintegrating is convenient, and the discharge capacity, the take-off that do not influence safety valve reach back seat.
