ABB PPD539A102 3BHE039770R0102逻辑8通道隔离卡件

ABB PPD539A102 3BHE039770R0102逻辑8通道隔离卡件氧化系统由萘蒸发器、鼓风机组、气萘混合系统、反应器、汽水平衡系统等组成。液萘通过萘蒸发器蒸发为气萘，在汽化器内与经过空气预热器加热的空气混合，然后进入反应器进行反应，反应过程中温度需维持在基本恒定，反应过程中释放大量热量，通过熔盐循环带走热量，熔盐循环过程中通过循环水减温，熔盐温度不可过低，否则将带走大量热量进而导致反应无法正常进行，熔盐温度也不可过高，否则将无法起到减温效果，为熔盐减温的循环水将变为蒸汽，在汽水系统中流通，提供给汽轮机等设备使用。在萘法制苯酐工艺中，床温、盐温起着至关重要的作用，直接关系到正常生产及人员设备安全问题，若采用单纯的温度分布表罗列数量众多的床温、盐温数据，操作人员极难在繁多的温度数据中把握床温、盐温趋势并找出异常点位。在本系统中以曲线的形式表达同一列不同深度床温/盐温温度趋势，使温度随着深度变化而变化的趋势变得一目了然，同时同一深度不同测温点间的温差也清晰可见，使得操作人员不再依赖于直观度较差的温度表格，极大程度地方便操作人员对于床温/盐温的把控。The oxidation system consists of naphthalene evaporator, blower unit, gas naphthalene mixing system, reactor, steam water balance system, etc. The liquid naphthalene is evaporated into gas naphthalene through the naphthalene evaporator, mixed with the air heated by the air preheater in the vaporizer, and then enters the reactor for reaction. During the reaction, the temperature needs to be kept basically constant, a lot of heat is released during the reaction, and the heat is taken away through the molten salt circulation. During the molten salt circulation, the temperature of the molten salt is reduced through the circulating water, and the temperature of the molten salt cannot be too low, otherwise, a lot of heat will be taken away and the reaction cannot be carried out normally, The temperature of molten salt shall not be too high, or it will not have the effect of temperature reduction. The circulating water for temperature reduction of molten salt will become steam, which will circulate in the steam water system and be provided for steam turbine and other equipment. In the naphthalene phthalic anhydride process, the bed temperature and salt temperature play a vital role, which is directly related to the normal production and personnel and equipment safety. If a simple temperature distribution table is used to list a large number of bed temperature and salt temperature data, it is extremely difficult for operators to grasp the bed temperature and salt temperature trends and find out the abnormal points among the various temperature data. In this system, the trend of bed temperature/salt temperature at different depths in the same column is expressed in the form of curve, so that the trend of temperature changes with depth becomes clear at a glance. At the same time, the temperature difference between different temperature measuring points at the same depth is also clearly visible, so that operators no longer rely on temperature tables with poor visibility, which greatly facilitates operators' control of bed temperature/salt temperature.
