中文摘要：化工原理课程设计是化工原理教学中综合性和实践性的教学环节，是理论联系实际的桥梁，是使学生体察工程实际问题复杂性、学习化工设计基本知识的初次尝试。本次《水吸收氨过程的填料吸收塔设计》可以使同学们的综合能力得到进一步的加强，锻炼了同学们在日常生活以及以后的工作学习中的查阅有关科学文献的能力，进一步锻炼了同学们的设计能力、计算能力、表达能力，同时也培养了同学们的环保意识、节能意识。填料塔吸收净化不仅在化工领域，在一般浓度乃至低浓度的工业净化方面也发挥着不可磨灭的作用。不计其数的工程实践表明，合理的系统工艺流程与填料吸收塔的设计可以充分保证一定的净化效果。本次设计是将聚丙烯阶梯环应用于水吸收氨气的填料吸收塔的设计。在同样条件下，采用逆流方式较并流可以获得最大化的平均推动力，进而可以获得一个更大的吸收效率。另外，由于在采用逆流过程中吸收剂的流向与气体的流向是完全相反的，所以这种方式有利于进一步提高溶质的吸收率，并且能最大化的减少自手机的损耗用量。因此，无论从效率角度还是从经济角度讲采用逆流比采用并流要合适。通过一系列资料、文献以及操作条件，我们可以计算出泛点气速、空塔气速、塔径、塔的横截面积，进一步计算出传质单元高度、传质单元数，最终计算出填料吸收塔的高度。

英文摘要：Principles of chemical engineering course design is the teaching of the principles of chemical engineering is a comprehensive and practical teaching link, is the bridge of theory with practice, which is to enable students to observe actual engineering problem complexity, learning basic knowledge of chemical engineering design first try. The packing of the process of the water absorption of ammonia absorption

tower design can make the students' comprehensive ability to further strengthen, exercise the students in their daily life and in the later work study ability to consult relevant scientific literature, further develop the students ability of design, calculation ability, expression ability, and cultivate the students consciousness of environmental protection, energy saving consciousness. Packed tower absorption in the field of chemical industry, not only in general concentration and low concentration of industrial purification also plays an indelible role. A countless number of engineering practice shows that reasonable system technological process and filler in absorption tower design can fully guarantee of purification effect. This design is to packing of polypropylene ladder ring is applied to the water absorption of ammonia absorption tower design. Under the same conditions, using the counter-current mode and flow can maximize the average driver, which can obtain a greater absorption efficiency. In addition, as a result of the sorbet in the process of using counter-current flow and the flow of gas is opposite, so this way is conducive to further improve the solute absorption rate, and can maximize reduce the wastage of the mobile phone usage. Therefore, no matter from the Angle of efficiency or from an economic point of view adopted more suitable than the adoption and flow upstream. Through a series of data, literature, and operating conditions, we can calculate the flood point gas velocity, superficial gas
