廢氣吸(xi)收塔除(chu)(chu)霧裝(zhuang)(zhuang)置沖(chong)(chong)洗(xi)周期(qi)(qi)是(shi)指除(chu)(chu)霧裝(zhuang)(zhuang)置每(mei)次(ci)沖(chong)(chong)洗(xi)的時間(jian)(jian)間(jian)(jian)隔(ge)。由于(yu)(yu)除(chu)(chu)霧裝(zhuang)(zhuang)置沖(chong)(chong)洗(xi)期(qi)(qi)間(jian)(jian)會導致煙(yan)氣帶水量加(jia)大(一般為(wei)不(bu)沖(chong)(chong)洗(xi)時的3~5倍)。所以(yi)沖(chong)(chong)洗(xi)不(bu)宜過于(yu)(yu)頻繁，但也不(bu)能(neng)間(jian)(jian)隔(ge)太長，否則易產生(sheng)結(jie)垢現象，除(chu)(chu)霧器的沖(chong)(chong)洗(xi)周期(qi)(qi)主要根據(ju)煙(yan)氣特征及吸(xi)收劑(ji)確(que)定(ding)，一般以(yi)不(bu)超過2h為(wei)宜。
