【摘要】：對(duì)于采用傳統(tǒng)的離子交換除鹽系統(tǒng)和全膜處理技術(shù)系統(tǒng)生產(chǎn)鍋爐補(bǔ)給水的供熱機(jī)組而言,其影響蒸汽氫電導(dǎo)率的主要因素分別是原水中有機(jī)物的殘留物和還原性環(huán)境中細(xì)菌的大量繁殖。將凝膠型陰樹脂換成去除有機(jī)物效果較好的D213大孔型陰樹脂可顯著降低傳統(tǒng)的離子交換除鹽系統(tǒng)出水總有機(jī)碳(total organic carbon,TOC);在超濾前后投加非氧化性殺菌劑,均可有效殺滅穿透超濾的細(xì)菌。過(guò)熱蒸汽壓力為12.7~18.3MPa和18.3MPa的鍋爐補(bǔ)給水TOC的標(biāo)準(zhǔn)值應(yīng)分別控制為≤400/Nμg/L和≤200/Nμg/L(N%為供熱機(jī)組的補(bǔ)水率,N1)。保證過(guò)熱蒸汽壓力18.3MPa的汽包爐和直流爐蒸汽質(zhì)量氫電導(dǎo)率(25℃)標(biāo)準(zhǔn)值合格(氫電導(dǎo)率≤0.10μS/cm)的給水TOC標(biāo)準(zhǔn)值應(yīng)為≤50μg/L。
[Abstract]:For the heating unit which uses the traditional ion exchange desalination system and the whole film treatment system to produce the boiler recharge water, The main factors that affect the hydrogen conductivity of steam are the residual organic matter in raw water and the mass propagation of bacteria in reducing environment. Replacing the gel anion resin with D213 macroporous anion resin with better removal of organic matter can significantly reduce the total organic carbon (total organic) in the effluent of the traditional ion exchange desalination system, and add non-oxidizing fungicides before and after ultrafiltration. Can effectively kill bacteria penetrating ultrafiltration. The standard values of TOC of boiler feedwater with superheated steam pressure of 12.7 and 18.3 MPA should be controlled to 鈮，
