　　二、吹管消聲器特點

　　(1)消聲量大，降噪量可達25dB～35dB（A）。

　　(2)能承受(shou)各種工(gong)業垃圾的猛烈撞擊，并(bing)順(shun)利(li)排出(chu)，在惡劣的工(gong)作條件下也(ye)能正常工(gong)作，且不(bu)影響(xiang)吹管(guan)的蒸汽(qi)流量；

　　(3)可適用于多(duo)種吹(chui)管(guan)方(fang)式(shi)：穩壓(ya)吹(chui)管(guan)、降壓(ya)吹(chui)管(guan)、加氧吹(chui)管(guan)。

　　(4)安裝方便（一般需特(te)定地基水平(ping)安裝），分室內和室外(wai)吹管(guan)。

　　1、吹管氣(qi)體壓(ya)力溫度。

　　2、吹管進口通徑(jing)、壁(bi)厚。

　　3、排放量。
