中央空調通風管道怎么清洗消毒除塵？詳細施工流程如下中央空調通風管道內，在長期使用中，會積聚大量的灰塵，不但會嚴重污染室內的空氣，而且會增加風管系統(tǒng)阻力，使中央空調系統(tǒng)的風量下降。更重要的是，風管內空氣的溫度和濕度非常適宜有害細菌的生長和繁殖，直接成為一個隱秘的污染源。 </p> <p> 集中式通風管道除塵、清洗和消毒流程 </p> <p> <br /> </p> <p> 一、清洗前的準備 </p> <p> <br /> </p> <p> <br /> </p> <p> 1.1、根據(jù)安裝圖紙和所要施工的現(xiàn)場了解新風管、回風管、送風管系統(tǒng)的布局； </p> <p> 1.2、以風管系統(tǒng)為單位除塵、清洗和消毒； </p> <p> 1.3、選定清洗口和吸塵口，如使用第六代管道機器人，在選擇清洗口口，對清洗單元的末端進行封閉，清洗和收塵同時在清洗完成； </p> <p> 1.4、使用通風管監(jiān)視監(jiān)控系統(tǒng)檢查管道內污染程度、管道結構內特點，結合通風管道的尺寸和距離地面的高度，選擇合適的清洗設備（管道機器人、軟軸）。 </p> <p> <br /> </p><p>

一、測定位置和測定點 </p> <p> (一)測定位置的選擇 </p> <p> 通風管道內風速及風量的測定，是通過測量壓力換算得到。測得管道中氣體的真實壓力值，除了正確使用測壓儀器外，合理選擇測量斷面、減少氣流擾動對測量結果的影響很大。測量斷面應盡量選擇在氣流平穩(wěn)的直管段上。測量斷面設在彎頭、三通等異形部件前面(相對氣流流動方向)時，距這些部件的距離應大于2倍管道直徑。當測量斷面設在上述部件后面時，距這些部件的距離應大于4～5倍管道直徑。當測試現(xiàn)場難于滿足要求時，為減少誤差可適當增加測點。但是，測量斷面位置距異形部件的**小距離至少是管道直徑的1.5倍。 </p> <p> <p> (二)測試孔和測定點 </p> <p> 由于速度分布的不均勻性，壓力分布也是不均勻的。因此，必須在同一斷面上多點測量，然后求出該斷面的平均值。 </p> <p> 1圓形風道 </p> <p> 在同一斷面設置兩個彼此垂直的測孔，并將管道斷面分成一定數(shù)量的等面積同心環(huán)，對于圓形風道，測點越多，測量精度越高。 </p> <p> <br /> </p>

(1)標準畢托管 </p> <p> 它是一個彎成90°的雙層同心圓管，其開口端同內管相通，用來測定全壓；在靠近管頭的外壁上開有一圈小孔，用來測定靜壓，按標準尺寸加工的畢托管校正系數(shù)近似等于1。標準畢托管測孔很小，易被風道內粉塵堵塞，因此這種畢托管只適用于比較清潔的管道中測定。 </p> <p> (2)S型畢托管 </p> <p> 它是由兩根相同的金屬管并聯(lián)組成，測量時有方向相反的兩個開口，測定時，面向氣流的開口測得的相當于全壓，背向氣流的開口測得的相當于靜壓。由于測頭對氣流的影響，測得的壓力與實際值有較大誤差，特別是靜壓。因此，S型畢托管在使用前須用標準畢托管進行校正，S型畢托管的動壓校正系數(shù)一般在0.82～0.85之間。S型畢托管測孔較大，不易被風道內粉塵堵塞，這種畢托管在含塵污染源監(jiān)測中得到廣泛應用。
