The filler tower has efficient and higher, the flux is more big and press to decline lower, hold the amount of liquid smaller characteristics, operate in the low pressure, the hot and quick sex thing fasten of separate and economy energy the aspect have its special advantage.The article elaborated a waste gas recovery to equip the method of the row spirit and the process of the row spirit, according to design the row measure 40000 request to design the parameter of each parts, introduced inside tower of always press a strong calculation method for declining, pressure in the air piping loss and leave the choice of the heart well ventilated machine.The air liquid which resolves to appear in the process of lining up spirit is suffused with and holds an amount of liquid problem.Passing the need chooses to use of various subsidiary device of filler tower.

Mechanical English translation : Keywords : Packed Tower, centrifugal fan, pressure drop, fillersAbstract subsidiary device packed tower with a higher efficiency, higher throughput, lower pressure drop, liquid holdup smaller features, the low-pressure operation, Heat-sensitive matter of the separation and energy has its unique advantages. The article elaborated Recovery exhaust emissions and the exhaust of the process, Displacement 40,000 in accordance with the design requirements of the various components of the design parameters of the total column pressure drop calculation method gas pipelines and the pressure loss centrifugal fan choice. In the settlement process exhaust gases emerging flooding and liquid holdup problem. Through the use of fill material needs of the various subsidiary tower installations.

直齿显示Fig.7.13将有一个牙齿接触工件在任何时候。当切割启动时，它启动的最大切屑厚度，降低到零，然后在下一个牙齿接触到工件。其结果是，切削力上升到最高值，然后迅速下降到零之前再次上升显示Fig.7.14 （一） 。这支部队的变化引起的影响负荷对铣刀和诱导振动。对于螺旋铣刀每齿长于直齿。因此，在任何特定时间超过一个牙齿将接触工件，每个具有不同的芯片厚度。其结果是，切削力变化将稳定显示Fig.7.14 （ b ）项。 7.3.2向上和向下铣削 基于方向运动的铣刀和喂养方向工件，有两种可能的类型的铣床： （一）最多铣（传统铣削） （二）涨铣（攀登铣） 最多最多铣削铣削刀具旋转相反的方向运动的表。在常规或铣削，该芯片启动零厚度，并逐步增加的最大大小显示Fig.7.15 （一） 。这往往使工件从表。有一种可能性，即刀具将磨工件开始之前取消。然而，这个过程本身是安全的。 最初摩擦的尖端开始时降低了铣削往往沉闷的前沿，因此有降低刀具寿命。也因为刀倾向于削减和幻灯片或者，表面生成的是剩下的加工痕迹。 下跌铣（攀登铣）在下跌铣削刀具旋转的方向是一致的，在表运动。在攀登或向下铣，该芯片启动的最大厚度和去零厚度逐渐显示Fig.7.15 （ b ）项。这是适合获得优良成绩的工件。切削力行为向下，因此保持工件的工作中坚定地举行设备。这是一个好薄和脆弱的工件。 在这种情况下，切削力方向以及丝杠运动正朝着同一个方向，有可能的反弹本表中的丝杠，都会造成干扰的实际运动的表，使干。有时工作会牵扯到刀具，这可能导致骨折铣刀或损坏工件。这有时可能是危险的机床以及。该芯片最大厚度开头，这给大部队，这将需要照顾的刚性丝杠表喂养。
