</p><p>鍋爐排氣消聲器是電廠專用設備，適用于高壓、中壓、超高壓氣體排放消聲，主要基于小孔噴射理論和阻抗擴展吸聲消聲功能的開發和設計。電廠鍋爐蒸汽排放一般流速較大。實驗表明，消聲量與流速有關，流速較高，氣流再生噪聲增加，消聲性能下降，因此，我們首先通過孔安全控制流量，一次通過孔后，蒸汽進入擴張室進一步降壓降流。大容積降壓后，蒸汽形成低壓蒸汽，低流速對小孔噴射消聲幾乎沒有影響。在這個過程中，氣流通過小孔徑噴射后，各倍頻帶的聲功率降低，聲壓級頻率提高到20000Hz以上。其噪聲大大減弱，但有些頻率的二次噪聲需要進一步消除。我們在擴張室外安裝了阻力吸聲棉結構。它是根據降壓體的剩余噪聲特性設計的，用于有效吸收剩余噪聲。當用戶按要求安裝時，總消耗量達到30-4分鐘，但有些頻率的二次噪聲音需要進一步消除。使之達到工業企業噪聲標準的要求。</p><p>應用鍋爐排汽消聲器。</p><p>鍋爐排氣消聲器具有針對性強、中低頻吸聲效果明顯、無吸聲材料等特點。一般來說，它只能用于小管道的排氣和消聲，如汽車、船舶、柴油機和其他排氣和消聲。特別是發電部門的鍋爐蒸汽不僅具有高溫高壓，而且具有排放頻帶寬的頻帶寬消聲器，不僅具有較大的消聲能力，而且適應頻帶寬的設計（針對低中壓、次高壓、超高壓、亞臨界等壓力參數）。</p><p><br/></p></div>
