空冷器噪音的來源及解決辦法

2025-01-10 13:26:09 admin 閱讀(1621)

工業噪聲,是指在工業生產活動中使用固定的設備時產生的干擾周圍生活環境的聲音。在煉油廠的生產活動中,空冷器噪音是主要噪聲之一,它與加熱爐、機泵等并列為煉油廠的主要噪聲源。隨著環保工作的日益加強,空冷器噪聲問題也顯得突出起來。

空冷器的噪聲主要是風機轉動引起的噪聲,它的大小與風機葉片的轉速有關。風機葉片在高速轉動時,空氣形成紊流,風機葉片的背面形成空氣渦流,最終產生空氣的呼嘯聲。有分析認為,風機噪聲占空冷器全部噪聲的80%。電機噪聲和傳動機構的噪聲也是噪聲來源的一部分。還有一點就是,空氣流過空冷器管束時,壓降過大,產生噪聲。

空冷器一般不會單臺運行,一般都會成組配置,設備布置相對集中,噪聲通過多臺設備的噪聲疊加,影響范圍較大。

我公司針對空冷器噪聲產生的原因,防治空冷器噪音的方法主要是源頭防控和過程治理。

源頭防控

1、降低空冷器噪音要從源頭抓起,采用低噪聲風機,從根本上解決問題。

2、提高了風筒和構架的剛度。

3、提高傳動機構的精度。

4、根據工藝選型要求,適當的加大管束中翅片管間距或者減少管排數,以降低空氣穿過管束時的壓降。

5、采用低噪聲電機。

過程治理

1、設置隔聲墻、隔聲板、加高風筒等。

2、在電機上設置隔聲罩。

我公司通過以上措施對空冷器設備進行優化后,達到了很好的降噪效果,獲得了廣大業主的一致好評。空冷器二維碼.jpg
