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.
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.
