Description

一种转切频率式消音器
技术领域
本发明涉及机械设备领域,尤其是涉及一种转切频率式消音器。
背景技术
消音器是阻止声音传播而允许气流通过的一种器件,是消除空气动力性噪声的重要措施。消音器是安装在空气动力设备(如鼓风机、空压机、锅炉排气口、发电机、水泵等排气口噪音较大的设备)的气流通道上或进、排气系统中的降低噪声的装置;在电站锅炉PCV/ERV安全阀(动力释放阀)、锅筒安全阀及过热器安全阀、再热器安全阀等压力装置的安全门,其蒸汽放空会产生过大的噪声,以往常见的多级节流及小孔喷注的消音降音手段效果差,需要消音的设备复杂。
发明内容
为克服上述问题,解决消音效果差的问题,本发明采用的技术方案如下:
一种转切频率式消音器,包括罐体,罐体两侧设有进出口,在罐体内壁设有消音频段,罐体内部两侧靠近出入口处设有转切频率器,转切频率器中间的形成的空间为消声容纳区。
转切频率器为锥形冲孔板网,能最大限度的消切频率,削弱噪音;转切频率器。
转切频率器、消声容纳区能够削弱、改变频率、吸收噪音。
本发明的优点:设备结构简单,实用、安装维修方便,安装在安装在空气动力设备的气流通道上或进、排气系统中可消除65%的噪音。
附图说明
图1是本发明的结构示意图。
具体实施方式
如图1所示,一种转切频率式消音器,包括罐体1,罐体1两侧设有进出口,在罐体1内壁设有消音频段2,罐体1内部两侧靠近出入口处设有转切频率器3,转切频率器3中间的形成的空间为消声容纳区4,消声容纳区4可再次吸收噪音。
转切频率器3为锥形冲孔板网,能最大限度的消切频率,削弱噪音;转切频率器。
转切频率器3、消声容纳区4能够削弱、改变频率、吸收噪音。
以上所述,仅为本发明的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本领域的技术人员在本发明所揭露的技术范围内,可轻易想到的变化或替换,都应涵盖在本发明的保护范围之内。因此,本发明的保护范围应该以权利要求书所限定的保护范围为准。
