消聲器的種類

消聲器概述

消聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)的(de)種(zhong)類(lei)(lei)很，但究其(qi)消聲(sheng)(sheng)(sheng)(sheng)機理，又(you)可以把(ba)它們分為六(liu)種(zhong)要的(de)類(lei)(lei)型，即阻消聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)、抗消聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)、阻抗復合式消聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)、微穿孔(kong)板消聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)、小孔(kong)消聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)和有(you)消聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)。

消聲器介紹

阻消聲器

要是利用孔(kong)吸聲(sheng)材料(liao)來降低(di)噪聲(sheng)的(de)(de)。把(ba)吸聲(sheng)材料(liao)固在氣流通道的(de)(de)內壁上(shang)或按(an)照方式在管道排列(lie)，就了(le)阻(zu)(zu)消(xiao)(xiao)(xiao)聲(sheng)器。當聲(sheng)波(bo)(bo)進入阻(zu)(zu)消(xiao)(xiao)(xiao)聲(sheng)器時，部分聲(sheng)能在孔(kong)材料(liao)的(de)(de)孔(kong)隙摩擦而轉化熱能耗散(san)掉，使通過(guo)消(xiao)(xiao)(xiao)聲(sheng)器的(de)(de)聲(sheng)波(bo)(bo)減(jian)弱。阻(zu)(zu)消(xiao)(xiao)(xiao)聲(sheng)器就象電(dian)學(xue)上(shang)的(de)(de)純電(dian)阻(zu)(zu)電(dian)路，吸聲(sheng)材料(liao)類似(si)于(yu)電(dian)阻(zu)(zu)。因(yin)此，人們就把(ba)這種消(xiao)(xiao)(xiao)聲(sheng)器稱為(wei)阻(zu)(zu)消(xiao)(xiao)(xiao)聲(sheng)器。阻(zu)(zu)消(xiao)(xiao)(xiao)聲(sheng)器對頻消(xiao)(xiao)(xiao)聲(sheng)遙(yao)遙(yao)、對低(di)頻消(xiao)(xiao)(xiao)聲(sheng)遙(yao)遙(yao)較差(cha)。(要應用于(yu)發(fa)電(dian)機(ji)機(ji)消(xiao)(xiao)(xiao))

阻抗復合式消聲器

由阻結和抗結按照的(de)方式合。

微穿孔板消聲器

般是用(yong)厚度小于1mm的(de)(de)(de)純金屬薄板制作，在薄板上用(yong)孔徑小于1mm的(de)(de)(de)鉆(zhan)頭(tou)穿孔，穿孔率為1%3%。選擇(ze)不(bu)同(tong)的(de)(de)(de)穿孔率和(he)板厚不(bu)同(tong)的(de)(de)(de)腔(qiang)，就可以控制消(xiao)聲器的(de)(de)(de)頻(pin)譜能，使(shi)其在需要的(de)(de)(de)頻(pin)率范圍內得良(liang)的(de)(de)(de)消(xiao)遙遙。

小孔消聲器

結是(shi)(shi)根末(mo)端封(feng)閉的(de)(de)直管(guan)，管(guan)壁上鉆有很小(xiao)孔(kong)。小(xiao)孔(kong)消聲器的(de)(de)原理(li)是(shi)(shi)以(yi)噴氣噪聲的(de)(de)頻譜為依據的(de)(de)，如果保持噴口(kou)的(de)(de)總面積不變而用很小(xiao)噴口(kou)來(lai)代替，當氣流經過小(xiao)孔(kong)時(shi)、噴氣噪聲的(de)(de)頻譜就(jiu)會移向頻或頻，使頻譜的(de)(de)可(ke)聽聲分明(ming)降低，從(cong)而減少對人的(de)(de)干擾(rao)和傷害(hai)。

有消聲器

基本(ben)原理是在原來的聲(sheng)場(chang)，利用電子設備(bei)再產生個與(yu)原來的聲(sheng)壓(ya)小相等、相位(wei)相反(fan)的聲(sheng)波，使其在范圍內與(yu)原來的聲(sheng)場(chang)相抵消。這種消聲(sheng)器(qi)(qi)是套(tao)儀(yi)器(qi)(qi)裝置，要由聲(sheng)器(qi)(qi)、放器(qi)(qi)、相移裝置、功率放器(qi)(qi)和揚(yang)聲(sheng)器(qi)(qi)等。

消聲器的衡量指標

衡量消(xiao)聲器(qi)(qi)的壞，要考慮以下三個方面(mian)： 1、消(xiao)聲器(qi)(qi)的消(xiao)能；（消(xiao)量和頻譜） 2、消(xiao)聲器(qi)(qi)的空氣動力能；（壓(ya)力損(sun)失等(deng)(deng)） 3、消(xiao)聲器(qi)(qi)的結能。（尺寸、格、等(deng)(deng)）

蒸汽排空消聲器

：用途及(ji)產 　鍋(guo)爐(lu)蒸(zheng)(zheng)汽(qi)(qi)消(xiao)(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)器要(yao)(yao)用于電力、石(shi)油(you)、化工(gong)(gong)、冶金、紡(fang)織等工(gong)(gong)業的(de)(de)(de)鍋(guo)爐(lu)蒸(zheng)(zheng)汽(qi)(qi)排放及(ji)其它氣體消(xiao)(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)排放的(de)(de)(de)消(xiao)(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)。是消(xiao)(xiao)(xiao)(xiao)除(chu)蒸(zheng)(zheng)汽(qi)(qi)排放噪聲(sheng)(sheng)(sheng)的(de)(de)(de)要(yao)(yao)措施。各類鍋(guo)爐(lu)排汽(qi)(qi)蒸(zheng)(zheng)汽(qi)(qi)不(bu)僅溫(wen)壓(ya)(ya)，且排放頻帶(dai)寬，衡量(liang)蒸(zheng)(zheng)汽(qi)(qi)排放消(xiao)(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)器的(de)(de)(de)壞，要(yao)(yao)考慮以下三個方(fang)面： 1、鍋(guo)爐(lu)蒸(zheng)(zheng)汽(qi)(qi)消(xiao)(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)器的(de)(de)(de)消(xiao)(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)量(liang)能(neng)滿(man)足《工(gong)(gong)業企業噪聲(sheng)(sheng)(sheng)標準(zhun)》的(de)(de)(de)要(yao)(yao)求。 2、消(xiao)(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)器能(neng)適應不(bu)同頻率、溫(wen)和壓(ya)(ya)力(低壓(ya)(ya)、壓(ya)(ya)、亞臨界(jie)、臨界(jie))。 3、消(xiao)(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)器的(de)(de)(de)結(jie)（尺(chi)寸合理(li)、強度、長(chang)、安裝方(fang)便）。

二、消聲(sheng)(sheng)(sheng)器原理(li) 　鍋爐(lu)蒸(zheng)汽消聲(sheng)(sheng)(sheng)器是要建(jian)立在“小孔(kong)(kong)噴注”理(li)論結(jie)合阻抗擴容吸聲(sheng)(sheng)(sheng)的(de)消聲(sheng)(sheng)(sheng)原理(li)，鍋爐(lu)蒸(zheng)汽排放般流(liu)速，氣流(liu)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)，需以通(tong)孔(kong)(kong)擴流(liu)，經過次通(tong)孔(kong)(kong)后的(de)蒸(zheng)汽在抗擴張室得(de)到降(jiang)壓降(jiang)流(liu)，氣流(liu)再經小孔(kong)(kong)噴出，噴出后其各倍頻帶的(de)聲(sheng)(sheng)(sheng)功率已(yi)降(jiang)低(di)，而聲(sheng)(sheng)(sheng)壓的(de)頻率被到20000Hz以上范圍，其噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)為削弱，但部(bu)分頻率的(de)二次噪(zao)(zao)(zao)還需要進步(bu)消聲(sheng)(sheng)(sheng)，我們在擴張室外(wai)加裝(zhuang)阻吸聲(sheng)(sheng)(sheng)棉結(jie)，它系(xi)根據 降(jiang)壓體所發出的(de)剩余噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)的(de)頻譜所設計，用以地吸收剩余噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)。當用戶按要求安裝(zhuang)后，消聲(sheng)(sheng)(sheng)量(liang)可達30-42分貝(bei)。使之達到<<工(gong)業(ye)企業(ye)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)標準>>要求。

三、消(xiao)(xiao)聲器(qi)購選型(xing) 　鍋爐蒸(zheng)(zheng)汽(qi)(qi)消(xiao)(xiao)聲器(qi)是按各參(can)數(shu)要求進行心設計，在訂(ding)購排(pai)汽(qi)(qi)消(xiao)(xiao)聲器(qi)時須提供下列料，才能得的消(xiao)(xiao)聲遙(yao)遙(yao)： （1）蒸(zheng)(zheng)汽(qi)(qi)排(pai)放量(liang)少(T/h)、壓力、溫度(du)。 （2）排(pai)汽(qi)(qi)管通徑、壁厚。 （3）結(jie)可選小孔(kong)式(shi)或(huo)抗噴阻復合型(xing)。般用戶選購復合型(xing)消(xiao)(xiao)聲器(qi)，消(xiao)(xiao)聲遙(yao)遙(yao)，材質(zhi)內部為不銹鋼，殼(ke)體材料為碳(tan)鋼；接管可選取焊(han)接或(huo)法蘭對接；支(zhi)腿可選取腿式(shi)或(huo)耳式(shi)結(jie)；
