摘要设计总说明：Cl2，分子量约71，在20摄氏度左右时，氯气的颜色是黄中带绿的颜色，拥有让人呼吸难受的气体，氯气是有毒的气体，对人的身体有很多的伤害，如果人们通过呼吸吸入太多这种气体，可能会致死。氯气密度比空气大，大约为空气的2.5倍左右。氯气 能 溶 于 水，但 溶 解 度 不 大，温 度 越 高 氯 气 在 水 中 的 溶解度就会越小。氯气能溶于水，和水发生化学反应，生成两种强酸，这两种酸性物质具有腐蚀性。食盐电解生产的烧碱、氯气，在国民经济的很多部门都是很需要的，除了应用在于化学工业自身以外，在轻工业、纺织业、石油化工业、有色金属冶炼和公用事业等方面都有很多的用途，用途极为的广泛。20376

The preliminary design of an annual output of thirty thousand tons of caustic soda plant in chlorine treatment process
The general description of the design：
Cl2, a molecular weight of about 71, about 20 degrees Celsius, chlorine color is greenish yellow in color, have to let people breathe bad gas, chlorine is a toxic gas, the human body has a lot of damage, if people breathe in too many of these gases, may cause of death. Chlorine density than air, approximately 2.5 times the air. Chlorine can dissolve in water, but soluble solution is not big, the temperature is high chlorine gas solubility in water of the smaller. Chlorine can be dissolved in water, and the water chemical reaction, generate two strong acid, two acid is corrosive. Caustic soda, chlorine salt electrolysis production, are required in many sectors of the national economy, besides the application in chemical industry itself, there are many applications in the light industry, textile industry, petroleum chemical industry, non-ferrous metal smelting and utilities, use a very wide.
The main purpose of chlorine gas treatment method is the principle of caustic soda dechlorination in thirty thousand tons of caustic soda process of dechlorination device, relates to the calculation of. There are three major parts of caustic soda chlorine treatment, respectively is: cooling, drying and conveying reserve. The key stage of cooling is the use of titanium and chilled water cooler, concentrated sulfuric acid is mainly used in the drying process, the drying tower and other apparatus, parts, and then is the calculation of material, energy calculation, equipment selection and calculation for some.
1.The source of the task
The design is based on the "teachers know Shanghai Institute of Technology graduate design (Thesis) task book" to carry on the design, its purpose is to use the relevant knowledge of chemical engineering and technology studies and conducted a chemical design attempt.
