板式冷卻器輪回水體系的功用是將冷卻水(海水)送至上下壓凝氣器去冷卻汽輪機(jī)高壓缸排汽，以維持上下壓凝氣器的真空，使汽水輪回得以連續(xù)。它還向開式水體系和沖灰體系供應(yīng)用水。
The function of the plate cooling system is to send the cooling water (seawater) to the down pressure condenser to cool the steam turbine's high pressure cylinder, so as to maintain the vacuum of the upper and lower pressure condensers and make the steam water cycle continuous. In addition, it also supplies water to the open water system and the ash system.
1、應(yīng)只管即便運(yùn)用軟水或經(jīng)處置的產(chǎn)業(yè)輪回水,重要是制止結(jié)垢,以免影響換熱結(jié)果鈣離子節(jié)制在50-80mg/L 鎂離子節(jié)制在40-80mg/L 碳酸氫根離子節(jié)制在100-150mg/L 輪回水中氯離子的含量。
1, should try to use soft water or by the disposal of industrial circulating water, the important is to prevent fouling, so as not to affect the heat transfer results of calcium control in 50-80mg/L magnesium ion controlled content of chloride ion in water cycle in 100-150mg/L 40-80mg/L bicarbonate ion.
2、氯化物對不銹鋼輕易孕育發(fā)生應(yīng)力腐化，含量過高會在板片上孕育發(fā)生點(diǎn)蝕，招致油水混淆輪回水中氯離子的含量(當(dāng)水溫在60℃)：小于50mg/L板片資料可選用304 小于300mg/l板片資料可選用316L。
2, easily produce chloride on stainless steel stress corrosion, high levels of pitting pregnant in the plate, cause confusion oil-water chlorine ion content cycle (when the water temperature at 60 DEG C): 50mg/L data sheet can be used less than 304 less than the 300mg/l data sheet can be used 316L.
3、不銹鋼304、316L的實(shí)用范疇水、河水、油等普通的無機(jī)和無機(jī)介質(zhì)。304板式冷卻器可用于≤100℃的種種濃度的碳酸、氨水、和醇，在硫酸、鹽酸中的耐腐化性差，特別對含氯介質(zhì)惹起的漏洞腐化最敏感。316L的耐腐化性好一點(diǎn)。
3, stainless steel 304, 316L practical category of water, water, oil and other ordinary inorganic and inorganic medium. 304 can be used for various plate cooler is less than or equal to 100 DEG C, the concentration of carbonate and ammonia, alcohol, sulfuric acid and hydrochloric acid in the poor corrosion resistance, especially for chloride solution caused by the most sensitive corruption loopholes. 316L has a good resistance to decay.
所以我們在選購板式冷卻器的時候還是要考慮以上幾點(diǎn)內(nèi)容的，我們要避免一些不良情況的發(fā)生，希望各位能夠仔細(xì)的閱讀以上內(nèi)容。
So when we choose to buy plate cooler, we should consider the above contents. We should avoid some bad situations. I hope you can read the above contents carefully.
