Plastic Raschig Ring is the earliest developed random packing, and its height and outer diameter are equal. It was invented by German chemist Friedrich Rashig in 1914, and it also marked that the development of tower packing had entered the scientific track. However, in practical applications, it will often occur" Wall flow, runner flow" and other phenomena.

Features: High open rate,large gap, large flux, small resistance, so that the gas and liquid in the packed tower can pass freely, and the gas and liquid distribution in the packing layer is relatively well.

Applications: It can be used in drying towers, absorption towers, washing towers, regeneration towers, etc in the chemical, metallurgy, gas and oxygen production industries
