How to judge the activated alumina ball needs to be replaced?It can be seen from the following points:
1, see whether the activated alumina ball discoloration, yellow;
2, see whether the service life is more than two years, if more than two years should be replaced in time;
3, look at the treatment of gas humidity is too large, such as high humidity that activated alumina ball may fail;
4, see whether the fluorine content in fluorine water is obvious, such as the existence of obvious, it means that the activated alumina ball needs to be replaced.
Activated alumina ball for white spherical porous particles, particle size uniform, smooth surface, high mechanical strength, hygroscopicity, water absorption does not expand does not crack to maintain the original state, non-toxic, odorless, insoluble in water, ethanol.Under certain operating and regeneration conditions, the drying depth of activated alumina is as high as -70 ℃ below the dew point temperature.Activated alumina ball can be used as high fluoride water defluorine agent (defluorine capacity), alkyl benzene production of cyclic alkane defluorine agent, transformer oil deacid regeneration agent, used as oxygen industry, textile industry, electronic industry gas drying,Automated instrument wind drying, and in chemical fertilizer, petrochemical drying industry as a desiccant, purifying agent (dew point up to -40 degrees), in the air separation industry pressure swing adsorption dew point up to -55 degrees.It is an efficient desiccant for deep drying of trace water.High performance activated alumina in the amorphous refractory ingredients can bring the following benefits: improve the body density, fluidity, strength, increase the secondary mullite production, etc., reduce the water and porosity.In addition, activated alumina can also do desiccant, water absorption is large, drying speed is fast, can be regenerated (400-500K baking).
