Sieve plate tower. Tower plate using aperture and hole spacing of the larger shower drop tower plate. Nitrogen and water are from the sieve hole through. As the water cooling tower is not working continuously and steadily, the cooling effect is not ideal, so it is no longer used.
Cyclone plate. It consists of several metal structure of the cyclone tower plate, this type of structure resistance is very small, will not damage, has been used for quite a long time as an improved type, but the heat transfer effect is not as good as the packed tower.
Filled towers. Early is equipped with porcelain Rasigo ring, its heat transfer effect is still good, resistance is also not large, but in the use of low-pressure process since the clearance, due to switching system a few minutes to switch, when switching the emptying, the impact of airflow on the porcelain ring is larger, easy to cause the porcelain ring breakage, increased resistance. There is also a change to plastic rings to increase the strength.
