水吸收氨過程的填料吸收塔設(shè)計-化工原理課程設(shè)計論-文庫吧在線文庫
【正文】 氣、液之間的接觸面積。 （ 3） . 操作溫度下吸收劑的蒸汽壓要低，以為離開吸收設(shè)備的氣體往往被吸收劑所飽和，吸收劑的揮發(fā)度愈大，則在吸收和再生過程中吸收劑損失愈大。在同樣條件下，采用逆流方式較并流可以獲得最大化的平均推動力，進而可以獲得一個更大的吸收效率。填料塔吸收凈化不僅在化工領(lǐng)域，在一般濃度乃至低濃度的工業(yè)凈化方面也發(fā)揮著不可磨滅的作用。 prehensive 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 countercurrent 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 countercurrent 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 3 velocity, column diameter, crosssectional area of the tower, and further calculate the mass transfer unit height, mass transfer unit number, finally calculate the packing the height of the absorption tower. 目 錄 第 一 章 設(shè)計任務(wù)及設(shè)計方案 ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ 3 第 二 章
