DIFFUSER HEAD INDUCING THE GENERATION OF A PEAK FREQUENCY FOR MAXIMIZING NOISE-ABSORBING EFFICIENCY

摘要

PURPOSE: A diffuser head inducing the generation of a peak frequency is provided to guide noise components of exhaust gas or steam to a high frequency such as the peak frequency, thereby maximizing noise-absorbing efficiency by a noise absorbing material.;CONSTITUTION: A diffuser head inducing the generation of a peak frequency includes a supply unit (110), a first porous member (120), a second porous member (130), and a wire mesh (140). Gas or steam is supplied to the supply unit via an exhaust pipe (1) of a device. The first porous member is installed on a passage in which the gas or the steam supplied via the supply unit flows and includes a plurality of first holes (121) so that the gas or the steam is primarily passed through the first holes. The second porous member is installed on a passage in which the gas or the steam passed through the first holes of the first porous member flows and includes a plurality of second holes (131) so that the gas or the steam is secondarily passed through the second holes. The wire mesh is installed between the first and second porous members in multiple layers so that noise components of the gas or the steam pass through gratings of the wire mesh become a component of the peak frequency.;COPYRIGHT KIPO 2013
