阻抗型锅炉(lu)风(feng)机消(xiao)声(sheng)器用途(tu)及产品(pin)特点:

   风(feng)(feng)机(ji)是(shi)一种通(tong)用(yong)机(ji)械设备(bei),其使用(yong)范围很广,电力(li)、矿山、机(ji)械、冶金、化工等各行业(ye)的(de)生产均离(li)不开(kai)风(feng)(feng)机(ji)。风(feng)(feng)机(ji)在运(yun)转中(zhong)产生的(de)噪声(sheng)常常成为影(ying)响(xiang)工人健康和干(gan)扰环境的(de)祸源。特别是(shi)邻(lin)近生活区的(de)风(feng)(feng)机(ji),其进风(feng)(feng)口和出风(feng)(feng)口所辐射的(de)空气动力(li)性噪声(sheng),更是(shi)污染环境的(de)主要(yao)因素,形成公害(hai),是(shi)近年来我国工业(ye)部门(men)治理噪声(sheng)污染的(de)主要(yao)对象之一。 

      工业(ye)用风机,属连(lian)续运(yun)转之设备。国(guo)际标准(zhun)化组织(ISO)对此类设备所规定的噪(zao)声标(biao)准为≤90分贝,我国的(de)(de)新标准与(yu)此相(xiang)同,这也是工业企业连续(xu)性噪(zao)(zao)声(sheng)达标的(de)(de)依(yi)据,但在不采用消声(sheng)措施的(de)(de)情况下,风机进出(chu)风口向环境所射出(chu)的(de)(de)噪(zao)(zao)声(sheng)可达110120分贝,大大超(chao)过了达(da)标要求。

本型式(shi)(shi)风(feng)机消(xiao)(xiao)(xiao)(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)器(qi)系列产(chan)品(pin)为阻抗声(sheng)(sheng)(sheng)(sheng)流(liu)型。本厂(chang)根据(ju)对(dui)发电厂(chang)各类风(feng)机运行现场噪(zao)声(sheng)(sheng)(sheng)(sheng)源进行实(shi)(shi)际(ji)测试所取得的(de)濒(bin)特性资料(liao)来(lai)确(que)定在(zai)(zai)哪些频(pin)(pin)谱(pu)(pu)范围(wei)内需要多大消(xiao)(xiao)(xiao)(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)量作为设计吸(xi)(xi)声(sheng)(sheng)(sheng)(sheng)片结(jie)(jie)构及流(liu)体通(tong)道(dao)(dao)的(de)主要依据(ju),同时采(cai)用(yong)(yong)了具有较大吸(xi)(xi)声(sheng)(sheng)(sheng)(sheng)材(cai)料(liao)饰面的(de)狭(xia)矩形通(tong)道(dao)(dao),以(yi)增强吸(xi)(xi)收效果。J9九游会AG 知(zhi)道(dao)(dao),风(feng)机的(de)噪(zao)声(sheng)(sheng)(sheng)(sheng)源在(zai)(zai)大噪(zao)声(sheng)(sheng)(sheng)(sheng)级(ji)时,其频(pin)(pin)谱(pu)(pu)值往往不止一(yi)种,而(er)对(dui)不同频(pin)(pin)谱(pu)(pu)带(dai),对(dui)其消(xiao)(xiao)(xiao)(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)量要求也(ye)不相同。为此本风(feng)机消(xiao)(xiao)(xiao)(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)器(qi)采(cai)用(yong)(yong)了对(dui)高、中频(pin)(pin)噪(zao)声(sheng)(sheng)(sheng)(sheng)起(qi)消(xiao)(xiao)(xiao)(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)作用(yong)(yong)的(de)阻式(shi)(shi)结(jie)(jie)构及对(dui)中、低频(pin)(pin)噪(zao)声(sheng)(sheng)(sheng)(sheng)起(qi)消(xiao)(xiao)(xiao)(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)作用(yong)(yong)的(de)抗式(shi)(shi)结(jie)(jie)构,同时在(zai)(zai)阻式(shi)(shi)通(tong)道(dao)(dao)中采(cai)用(yong)(yong)了高频(pin)(pin)及低频(pin)(pin)两种消(xiao)(xiao)(xiao)(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)区(qu),用(yong)(yong)以(yi)大限度(du)的(de)增宽消(xiao)(xiao)(xiao)(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)频(pin)(pin)带(dai),以(yi)实(shi)(shi)现良好的(de)消(xiao)(xiao)(xiao)(xiao)(xiao)(xiao)声(sheng)(sheng)(sheng)(sheng)效果。本产(chan)品(pin)当用(yong)(yong)户按(an)要求安(an)装后,其极限噪(zao)声(sheng)(sheng)(sheng)(sheng)级(ji)将不超过8590分贝(bei)。

风机消声器


阻抗型(xing)通风、排(pai)气管道及风机消声器结(jie)构原理(li):
     锅炉
风(feng)机消(xiao)声(sheng)器(qi),排气(qi)管道消(xiao)音(yin)器(qi)以及鼓引风(feng)机消(xiao)声(sheng)器(qi)的形(xing)式均采(cai)用对(dui)中、高频宽带特性有较好(hao)效果的阻(zu)性吸(xi)音(yin)降噪原(yuan)(yuan)理,对(dui)低、中频和脉(mai)动特性时有良好(hao)效果的抗性消(xiao)声(sheng)降音(yin)原(yuan)(yuan)理以及微穿孔(kong)消(xiao)声(sheng)器(qi)和阻(zu)抗复合式消(xiao)声(sheng)器(qi)。 

    阻性(xing)锅炉风机消(xiao)(xiao)声(sheng)(sheng)器是一种(zhong)吸(xi)收型消(xiao)(xiao)声(sheng)(sheng)器,根据气流通道(dao)结构的不(bu)同(tong),一般分为直(zhi)管(guan)式(shi)(shi)、片式(shi)(shi)、折板(ban)式(shi)(shi)、蜂窝式(shi)(shi)、声(sheng)(sheng)流式(shi)(shi)、迷宫式(shi)(shi)和(he)弯头式(shi)(shi)等。阻性(xing)风机消(xiao)(xiao)声(sheng)(sheng)器是利用声(sheng)(sheng)波在多孔(kong)性(xing)吸(xi)声(sheng)(sheng)材料传(chuan)播时,受摩(mo)擦和(he)粘(zhan)滞阻力,将(jiang)声(sheng)(sheng)能转化为热能耗散掉,从而达到消(xiao)(xiao)声(sheng)(sheng)降音的目的。

    抗性(xing)锅炉风机消(xiao)(xiao)声(sheng)器它与阻性(xing)风机消(xiao)(xiao)声(sheng)器消(xiao)(xiao)声(sheng)降噪原理不同,它不能(neng)直接吸收声(sheng)能(neng),而是利用管(guan)道(dao)上突(tu)变(bian)的(de)(de)界(jie)面(mian)或旁接共振腔,使(shi)沿管(guan)道(dao)传播的(de)(de)某些频率声(sheng)波,在突(tu)变(bian)的(de)(de)界(jie)面(mian)处发生反射、干(gan)涉等现象,从而达到消(xiao)(xiao)声(sheng)降音的(de)(de)目的(de)(de)。分为扩张室式消(xiao)(xiao)声(sheng)器及(ji)共振式消(xiao)(xiao)声(sheng)器。

因在实际噪声(sheng)控(kong)制工程(cheng)中,噪声(sheng)以(yi)宽(kuan)频带居多(duo),通常(chang)将阻性吸音(yin)降(jiang)(jiang)噪声(sheng)及抗(kang)性消声(sheng)降(jiang)(jiang)音(yin)结构组(zu)合起来,以(yi)控(kong)制高(gao)强度的宽(kuan)频带噪声(sheng)。

 根据对(dui)工业用(yong)各(ge)类(lei)风(feng)机运行(xing)现场噪(zao)声(sheng)(sheng)源(yuan)进行(xing)实际测试所取得的频(pin)谱(pu)(pu)特性资(zi)料来确定在哪些(xie)频(pin)谱(pu)(pu)范围(wei)内需要多大(da)消(xiao)声(sheng)(sheng)量(liang)作(zuo)为设(she)计吸(xi)声(sheng)(sheng)体及流体通道(dao)(dao)的主要依据,同(tong)时采(cai)用(yong)了(le)具有较大(da)吸(xi)声(sheng)(sheng)材料饰面(mian)的狭矩形(xing)通道(dao)(dao),以增强吸(xi)收效果。另,风(feng)机的噪(zao)声(sheng)(sheng)源(yuan)在大(da)噪(zao)声(sheng)(sheng)级时,其频(pin)谱(pu)(pu)值往(wang)往(wang)不(bu)止一种,而对(dui)不(bu)同(tong)频(pin)谱(pu)(pu)带,对(dui)其消(xiao)声(sheng)(sheng)量(liang)要求也(ye)不(bu)相同(tong)。

为此ZF系列通(tong)风管道(dao)消(xiao)(xiao)(xiao)声(sheng)器及鼓(gu)引(yin)风机消(xiao)(xiao)(xiao)声(sheng)器均为阻(zu)(zu)(zu)抗型,采用了对(dui)高、中(zhong)频噪(zao)声(sheng)起吸音消(xiao)(xiao)(xiao)声(sheng)作用的(de)阻(zu)(zu)(zu)式结构及对(dui)中(zhong)、低频噪(zao)声(sheng)起消(xiao)(xiao)(xiao)声(sheng)降(jiang)音作用的(de)抗式结构,同(tong)时在阻(zu)(zu)(zu)式通(tong)道(dao)中(zhong)采用了高频及低频两种吸音消(xiao)(xiao)(xiao)声(sheng)区,用以大限度(du)的(de)增宽消(xiao)(xiao)(xiao)声(sheng)频带,以实现良好的(de)消(xiao)(xiao)(xiao)声(sheng)降(jiang)噪(zao)效(xiao)果。
