The evaporation loss is an important part of water loss in cooling tower and also is the maximum water consumption in thermal power plants. 文章对国内外加氢异构化基础油的主要理化性质进行了分析,考察了其粘度指数、蒸发损失、氧化安定性、倾点等性能的差异。
In a cooling tower, all three effects occur as evaporation takes place and the moisture is carried up the tower. 在一个冷却塔里,当发生蒸发而且水分被带上塔顶时,所有这三个作用都出现了。
Some water is lost through evaporation in the cooling tower and in waste discharge. 有些水在冷凝塔中蒸发掉了,有些则作为废水排放掉了。
To Decide the Evaporation Loss of Cold Water Tower 关于冷水塔蒸发损失的确定

Application of DJ-3 type tray on evaporation tower in reforming unit DJ-3型塔板在重整装置蒸发塔上的应用
Two methods deciding the evaporation loss of cold water tower using the empirical formula and the test are given and compared. The results are basically consistent. 提出用经验公式法和试验法两种方法确定冷水塔的蒸发损失,并对两种方法进行比较,结果基本一致。
Applying frequency governor to bottom pump of evaporation tower and feed pump of furnace, the result showed that it is the effective way to improve the automatic level in clay unit. 通过蒸发塔底泵和护进料泵两系统采用变频调速器的数据分析表明,它是提高白土精制装置自动化水平的有效途径。
The heat and mass transfer coefficient are calculated based on the experimental correlations mentioned above, and then the heat rejection and evaporation of the cooling tower are calculated. 根据实验获得的关联式,计算出冷却塔在不同条件下的换热系数、传质系数,进而计算冷却塔的换热量、蒸发量。
The injection height is an important factor effecting the flow characteristics of SDA. Injection too high or too low will cause uneven distribution of flow, lack of disturbance and excessive evaporation rate in the entire tower. 喷射高度是影响SDA内流动特性的重要因素,喷射过高或过低都会造成整个塔体内流场分布不均、扰动不足以及蒸发速率过快。
The evaporation per unit heat rejection has been adopted to measure the effect of cooling tower water conservation. 引入单位换热水蒸发量来评价冷却塔节水效果,同时将这些量与实测值进行比较。
