本次设计的任务是6万吨隔膜法制烧碱中氢气处理工序的初步设计。本次设计的主要意义在于，通过主要设备的工艺设计，工艺计算以及辅助设备选型和计算，找出一种最有效的处理氢气的方法，提高烧碱的产率，从而最大限度的利用氢气合成其他产品或者作为一种能源使用。 在本次设计中，首先对氢气做了物料衡算和热量衡算，并分别选取了一定的计算基准，以方便计算，由于从电解槽出来的氢气，含有饱和水蒸气同时还带有盐和碱的雾沫，所以在生产过程中先进行冷却和洗涤，冷却后的氢气经氢气压缩机压缩到一定压力后经氢气分配站送到氢气柜及用氢部门。因此本次设计应用到了换热器和冷却塔。其选型分别参照了《换热器设计》和《塔设备设计》。 关键词：氢气处理 工艺设计 工艺计算 设备选型 The design task is the preliminary design of the hydrogen treatment process 60,000 tons diaphragm legal caustic. The main significance of this design is the main equipment, process design, process calculation as well as auxiliary equipment selection and calculation, to identify the most effective method of handling hydrogen, increase the yield of caustic soda, in order to maximize the use of hydrogen synthesis other products or used as an energy source. In this design, the first hydrogen material balance and heat balance, and selected a certain basis of calculation in order to facilitate the calculation of hydrogen from the electrolyzer, contains saturated water vapor at the same time with the salt and the entrainment of the alkali in the production process, cooling and washing, and cooling of hydrogen by the hydrogen compressor compressed to a certain pressure, the hydrogen dispensing stations sent to the hydrogen cabinet and hydrogen sector. The design applied to a heat exchanger and cooling tower. Its selection, respectively, with reference to the heat exchanger design "and" tower equipment. Key words: hydrogen treatment process design process to calculate the selection of equipment |

The purpose of this work is to design the hydrogen treatment process 60,000 tons diaphragm legal caustic preliminarily. The main significance of this design lies in that through examinig the equipment selection and calculation of the main equipment, process design, process calculation as well as auxiliary , and to identify the most effective method of handling hydrogen and increase the yield of caustic soda. By this way ,the purpose of maximize the use of hydrogen into other products or used as energy has been achieved. Therein ,we firstly made a hydrogen material balance and heat balance, and selected a certain basis of calculation in order to facilitate the calculation of hydrogen from the electrolyzer, contains saturated water vapor at the same time with the salt and the entrainment of the alkali in the production process, cooling and washing, and cooling of hydrogen by the hydrogen compressor compressed to a certain pressure, the hydrogen dispensing stations sent to the hydrogen cabinet and hydrogen sector. thus the design applied the heating exchanger and cooling tower. we made the option-type with reference to the heat exchanger design "and" tower equipment,respectively. Key words: hydrogen processing technological design and calculation, equipment selection 你有很多都是用的翻译软件吧？呵呵～不要字字都翻译出来哈～那样句子太杂糅～ |
