廢氣吸收塔(ta)除(chu)(chu)霧(wu)(wu)裝(zhuang)置(zhi)沖(chong)(chong)(chong)洗(xi)(xi)周期是(shi)指(zhi)除(chu)(chu)霧(wu)(wu)裝(zhuang)置(zhi)每次沖(chong)(chong)(chong)洗(xi)(xi)的時(shi)間(jian)間(jian)隔(ge)。由于除(chu)(chu)霧(wu)(wu)裝(zhuang)置(zhi)沖(chong)(chong)(chong)洗(xi)(xi)期間(jian)會導致煙(yan)氣帶水量加(jia)大(一(yi)(yi)般為不(bu)(bu)沖(chong)(chong)(chong)洗(xi)(xi)時(shi)的3~5倍)。所以(yi)(yi)沖(chong)(chong)(chong)洗(xi)(xi)不(bu)(bu)宜過(guo)于頻繁，但(dan)也(ye)不(bu)(bu)能間(jian)隔(ge)太長(chang)，否則易(yi)產生結(jie)垢現(xian)象(xiang)，除(chu)(chu)霧(wu)(wu)器的沖(chong)(chong)(chong)洗(xi)(xi)周期主(zhu)要根據煙(yan)氣特征及(ji)吸收劑確定(ding)，一(yi)(yi)般以(yi)(yi)不(bu)(bu)超過(guo)2h為宜。
