　　二(er)、吹管消聲器特(te)點(dian)

　　(1)消聲(sheng)量大，降噪量可(ke)達25dB～35dB（A）。

　　(2)能承受各種(zhong)工(gong)業垃圾(ji)的猛烈撞擊，并順利排出，在(zai)惡劣的工(gong)作條件下(xia)也能正常工(gong)作，且不(bu)影響吹管的蒸汽流量；

　　(3)可適(shi)用于多種(zhong)吹(chui)(chui)管(guan)(guan)方式：穩壓吹(chui)(chui)管(guan)(guan)、降壓吹(chui)(chui)管(guan)(guan)、加氧吹(chui)(chui)管(guan)(guan)。

　　(4)安裝方便（一(yi)般需特定地(di)基(ji)水(shui)平(ping)安裝），分室內和室外(wai)吹管。

　　1、吹管氣體壓力溫度(du)。

　　2、吹管(guan)進口通徑、壁厚。

　　3、排放量。
