廢氣(qi)(qi)吸收塔除(chu)(chu)霧裝(zhuang)置沖(chong)(chong)(chong)洗周期是指除(chu)(chu)霧裝(zhuang)置每次沖(chong)(chong)(chong)洗的(de)時間(jian)(jian)間(jian)(jian)隔。由于除(chu)(chu)霧裝(zhuang)置沖(chong)(chong)(chong)洗期間(jian)(jian)會(hui)導(dao)致(zhi)煙氣(qi)(qi)帶水量加大(da)(一般為不沖(chong)(chong)(chong)洗時的(de)3~5倍)。所以沖(chong)(chong)(chong)洗不宜(yi)過于頻繁，但(dan)也(ye)不能間(jian)(jian)隔太長(chang)，否則易(yi)產(chan)生結垢(gou)現象，除(chu)(chu)霧器的(de)沖(chong)(chong)(chong)洗周期主要根據煙氣(qi)(qi)特征及吸收劑確定，一般以不超過2h為宜(yi)。
