隨著人們越來越注重身心健康，噪音治理行業在近幾年來也成為了一個熱門行業，那么今天西安噪音治理公司教您如何降低空壓機排氣口噪音。

排(pai)氣(qi)(qi)壓力(li)高、流量大的空(kong)壓機因產生的排(pai)氣(qi)(qi)噪聲(sheng)較高，在排(pai)氣(qi)(qi)系統需要(yao)設(she)置專用的消聲(sheng)器(qi)進行(xing)控制。排(pai)氣(qi)(qi)口消聲(sheng)器(qi)要(yao)求(qiu)消聲(sheng)量大，消聲(sheng)頻段寬，具有減壓擴(kuo)容(rong)，減小(xiao)排(pai)氣(qi)(qi)放空(kong)的壓力(li)落差的作用，以降(jiang)低排(pai)氣(qi)(qi)放空(kong)噪聲(sheng)。

對于流量小于20m3/min空壓機，噪聲(sheng)(sheng)不(bu)高且主要為高頻，一般可(ke)采用阻性消(xiao)聲(sheng)(sheng)器。阻性消(xiao)聲(sheng)(sheng)器的優點是能在較寬的中(zhong)高頻范圍內(nei)消(xiao)聲(sheng)(sheng)，特別對高頻聲(sheng)(sheng)波有突出的消(xiao)聲(sheng)(sheng)作用。阻性消(xiao)聲(sheng)(sheng)器利用氣流管道內(nei)不(bu)同(tong)結構形式的多孔吸(xi)聲(sheng)(sheng)材料(常稱(cheng)阻性材料)吸收聲(sheng)(sheng)能，降低噪聲(sheng)(sheng)的消(xiao)(xiao)聲(sheng)(sheng)器(qi)(qi)，是各類消(xiao)(xiao)聲(sheng)(sheng)器(qi)(qi)中形式(shi)(shi)最多、應用(yong)最廣的一種消(xiao)(xiao)聲(sheng)(sheng)器(qi)(qi)，且(qie)具有(you)(you)較(jiao)寬的消(xiao)(xiao)聲(sheng)(sheng)頻率范圍，在中、高頻率段消(xiao)(xiao)聲(sheng)(sheng)性能尤為顯著。阻性消(xiao)(xiao)聲(sheng)(sheng)器(qi)(qi)有(you)(you)下列幾種類型(xing)：管式(shi)(shi)消(xiao)(xiao)聲(sheng)(sheng)器(qi)(qi)、彎(wan)頭式(shi)(shi)消(xiao)(xiao)聲(sheng)(sheng)器(qi)(qi)、小(xiao)室式(shi)(shi)消(xiao)(xiao)聲(sheng)(sheng)器(qi)(qi)式(shi)(shi)、圓盤式(shi)(shi)消(xiao)(xiao)聲(sheng)(sheng)器(qi)(qi)。

但對于(yu)排氣壓(ya)力高(gao)和流(liu)量(liang)大的(de)(de)空(kong)壓(ya)機(ji)，由(you)于(yu)噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)聲(sheng)(sheng)(sheng)(sheng)壓(ya)級(ji)較(jiao)(jiao)大，既有(you)(you)(you)中(zhong)(zhong)低(di)頻(pin)噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)又有(you)(you)(you)高(gao)頻(pin)噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)，僅靠阻(zu)性(xing)消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)效(xiao)果是不理(li)想的(de)(de)，復(fu)合(he)(he)(he)消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)是解決問題的(de)(de)有(you)(you)(you)效(xiao)途徑，復(fu)合(he)(he)(he)式(shi)消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)的(de)(de)形式(shi)有(you)(you)(you)：阻(zu)抗(kang)(kang)復(fu)合(he)(he)(he)式(shi)，阻(zu)性(xing)及(ji)共(gong)振復(fu)合(he)(he)(he)式(shi)，抗(kang)(kang)性(xing)及(ji)微穿孔板復(fu)合(he)(he)(he)式(shi)等。復(fu)合(he)(he)(he)式(shi)消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)綜合(he)(he)(he)前種優點，由(you)于(yu)阻(zu)性(xing)消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)雖有(you)(you)(you)優良的(de)(de)中(zhong)(zhong)高(gao)頻(pin)消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)性(xing)能(neng)，而(er)低(di)頻(pin)消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)性(xing)能(neng)則較(jiao)(jiao)差，且難以提(ti)高(gao)，而(er)擴張式(shi)及(ji)共(gong)振式(shi)消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)則相反(fan)，在低(di)中(zhong)(zhong)頻(pin)具有(you)(you)(you)較(jiao)(jiao)好的(de)(de)消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)性(xing)能(neng)，高(gao)頻(pin)消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)效(xiao)果一(yi)般(ban)都較(jiao)(jiao)差。

若將(jiang)阻(zu)性與抗性兩種(zhong)消聲(sheng)(sheng)原理合成一種(zhong)消聲(sheng)(sheng)器(qi)，就可(ke)在較(jiao)寬(kuan)的(de)頻率(lv)范圍內得到(dao)滿(man)意的(de)消聲(sheng)(sheng)效果。這種(zhong)消聲(sheng)(sheng)器(qi)有共振腔、擴張室、穿孔屏等(deng)聲(sheng)(sheng)學濾(lv)波(bo)元(yuan)件(jian)又(you)有孔吸聲(sheng)(sheng)材料，對不同頻率(lv)的(de)噪聲(sheng)(sheng)均有消聲(sheng)(sheng)作用。
