板式冷却器轮回水体系的功用是将冷却水(海水)送至上下压凝气器去冷却汽轮机高压缸排汽,以维持上下压凝气器的真空,使汽水轮回得以连续。它还向开式水体系和冲灰体系供应用水。
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、应只管即便运用软水或经处置的产业轮回水,重要是制止结垢,以免影响换热结果钙离子节制在50-80mg/L 镁离子节制在40-80mg/L 碳酸氢根离子节制在100-150mg/L 轮回水中氯离子的含量。
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、氯化物对不锈钢轻易孕育发生应力腐化,含量过高会在板片上孕育发生点蚀,招致油水混淆轮回水中氯离子的含量(当水温在60℃):小于50mg/L板片资料可选用304 小于300mg/l板片资料可选用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、不锈钢304、316L的实用范畴水、河水、油等普通的无机和无机介质。304板式冷却器可用于≤100℃的种种浓度的碳酸、氨水、和醇,在硫酸、盐酸中的耐腐化性差,特别对含氯介质惹起的漏洞腐化最敏感。316L的耐腐化性好一点。
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.
所以我们在选购板式冷却器的时候还是要考虑以上几点内容的,我们要避免一些不良情况的发生,希望各位能够仔细的阅读以上内容。
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.
