工業(yè)熱水鍋爐為何不宜采用大氣
廣西中立源鍋爐廠家（咨詢熱線:158 7870 3621）生產(chǎn)供應生物質(zhì)鍋爐、燃氣鍋爐等。產(chǎn)品無煙無塵，節(jié)能環(huán)保。今天廣西中立源鍋爐廠家為您介紹：工業(yè)熱水鍋爐為何不宜采用大氣的問題，以下是小編對此問題的歸納整理，來看看吧。
對腐蝕介質(zhì)進行處理是防止腐蝕很常用的途徑，它又可分為：去掉介質(zhì)中的有害成分；在水中加入能減慢腐蝕的緩蝕劑。水中溶解的雜質(zhì)，易使金屬腐蝕的種類很多，尤其是溶解氧的存在，腐蝕特別嚴重。因此，給水除氧成為防止鍋爐、換熱器及管道腐蝕的首要任務(wù)。 熱水鍋爐流過的水量很大，直供系統(tǒng)這些水還要流過熱力管道和散熱器，其防止水側(cè)腐蝕問題不僅涉及熱水鍋爐，還涉及到整個熱水供熱系統(tǒng)(有些熱水鍋爐房都沒有蒸汽源)。總之，熱水鍋爐的除氧問題有其特殊性，往往比蒸汽鍋爐除氧存在的問題更多。 熱水鍋爐房無蒸汽源，故一般都不用大氣式熱力除氧。真空除氧可不用蒸汽加熱，但要增設(shè)一套抽真空裝置，并且系統(tǒng)要保持很不錯嚴密；除氧器要設(shè)置在7—8米的樓層上，故也很少用。過去曾采用過氧化還原樹脂除氧，其除氧效果好，水溫可以較低。但初期投資較大，更為不利的是失效后要用含毒性的水合肼還原。加亞硫酸鈉除氧，初投資較小，但加藥物等運行費用較高；水質(zhì)、水溫、PH、的過剩量的變化，對除氧效果影響較大。
中譯英： On the corrosion medium treatment is most commonly used to prevent corrosion of the way, it can be divided into: to remove harmful ingredients in medium; adding water can slow down the corrosion inhibitor. Dissolved impurities, the metal corrosion of many species, especially the presence of dissolved oxygen, particularly serious corrosion. Therefore, to prevent the boiler feed water deaerator become, heat exchanger and the primary task of pipeline corrosion. Hot water boiler with large amount of water flowing through the water, direct supply system which also flows through the heat pipe and radiator, which prevents water side corrosion problem involves not only hot water boiler, also relates to the hot water heating system(some hot water boiler room no steam source). In short, hot water boiler deaerator has its particularity, more often than steam boiler deaerator problems more. Hot water boiler steam source, so in general do not have atmospheric thermal deaerator. Vacuum deaeration without steam heating, but a set of vacuum pumping device, and the system will remain absolutely tight; deaerator to set in 7 - 8 meters of floor, it is also rarely used. Once the redox resin deoxidation, its good deoxidizing effect, the water temperature can be lower. But the initial investment is larger, more unfavorable is failure to use toxic hydrazine. Plus sodium sulfate removal, the initial investment is small, but with the addition of drugs and other operating costs; water quality, water temperature, PH, excess volume changes, on the deaerating effect.
