style="text-indent:25px">鍋爐消聲器是根據(jù)抗、噴、阻復(fù)合消聲原理研制，具有消聲量大、體積小、重量輕及安裝方便等優(yōu)點(diǎn)。鍋爐消聲器主要應(yīng)用于發(fā)電廠電站、熱電公司、石油化工、鋼鐵冶金、造紙印染、紡織、礦山等工礦企業(yè)的蒸汽鍋爐點(diǎn)火排汽消聲，蒸汽安全閥排汽消聲、鍋爐沖管消聲、背壓式汽輪機(jī)排汽消聲、高壓除氧器設(shè)備排汽消聲以及熱力系統(tǒng)蒸汽設(shè)備排放消聲降音。鍋爐消聲器是阻止聲音傳播而允許氣流通過的一種器件，是消除蒸汽排放動(dòng)力性噪聲的重要措施。衡量鍋爐消聲器的好壞，主要考慮以下三個(gè)方面：鍋爐消聲器的消聲量能滿足《工業(yè)企業(yè)噪聲衛(wèi)生標(biāo)準(zhǔn)》的要求；鍋爐消聲器的適應(yīng)性能；（即適應(yīng)低中頻譜寬帶和高溫高壓等）；鍋爐消聲器的結(jié)構(gòu)性能。（尺寸合理、造價(jià)低、壽命長(zhǎng)等）。</p><p style="text-indent:25px">微穿孔板式消聲器一般是用厚度小于1mm的純金屬薄板制作，在薄板上用孔徑小于1mm的鉆頭穿孔，穿孔率為1%一5%。選擇不同的穿孔率和板厚不同的腔深，就可以控制消聲器的頻譜性能，使其在需要的頻率范圍內(nèi)獲得良好的消聲效果。小孔式消聲器，小孔消聲器的結(jié)構(gòu)是一根末端封閉的直管，管壁上鉆有很多小孔。小孔消聲器的原理是以噴氣噪聲的頻譜為依據(jù)的，如果保持噴口的總面積不變而用很多小噴口來代替，當(dāng)氣流經(jīng)過小孔時(shí)、噴氣噪聲的頻譜就會(huì)移向高頻或超高頻，使頻譜中的可聽聲成分明顯降低，從而減少對(duì)人的干擾和傷害。有源式消聲器基本原理是在原來的聲場(chǎng)中，利用電子設(shè)備再產(chǎn)生一個(gè)與原來的聲壓大小相等、相位相反的聲波，使其在一定范圍內(nèi)與原來的聲場(chǎng)相抵消。這種消聲器是一套儀器裝置，主要由傳聲器、放大器、相移裝置、功率放大器和揚(yáng)聲器等組成。消聲器的消聲量越大，壓力損失及價(jià)格越大。</p><div
