Comparison of light porcelain and ceramic packing: The operation weight of light porcelain packing is lighter than that of ceramic packing, which can reduce tower body investment. The purification effect of light porcelain filler is better than that of ceramic filler. The surface of the light ceramic filler is porous and infiltrating, which can ensure the full touch of gas and liquid, extend the time of gas-liquid communication, and the purification effect is very ideal; while the surface of the ceramic filler is lubricated and the liquid residence time is short.
The gas-liquid communication is insufficient, and its useful specific surface area is low, and the application effect is not good. The applicability of light porcelain packing is better than ceramic packing. The light ceramic packing can be cut, and the circular packing tower can be packed evenly to prevent wall flow, bias flow and channel flow; while the ceramic packing is brittle and cannot be cut and cannot fill the circular packing tower with empty surroundings.
As a result, wall flow, partial flow and channel flow will be formed, which will seriously affect the application effect. The maintenance of light ceramic packing is more convenient than ceramic packing. The light ceramic packing has better thermal shock resistance and can be purged with high-temperature steam, which is convenient for maintenance; while the ceramic packing is not resistant to rapid cold and rapid heat, easy to explode and fragile, and cannot be purged with high-temperature steam, which is troublesome for maintenance. Comparison of light porcelain and metal filler.
Compared with light ceramic fillers, copper plate mesh has a small specific surface area and poor purification effect. Carbon steel fillers are not corrosion resistant and have a short service life. Stainless steel fillers are expensive, and metal fillers are the same as plastic fillers and ceramic fillers. The surface is lubricated and has no infiltration. Sex, affect the application effect.
