Activated alumina application in air dryer will be clarify in here.
What is activated alumina Precautions in air dryers.
Some clients don’t know Activated alumina application in air dryer. As the main body of the air dryer, the adsorbent is subjected to frequent pressure, water vapor and heat shocks , easily leads to broken by the mechanical and is defaced by the medium, deteriorating the performance of the adsorbent. Since activated alumina replaces silica gel as the main adsorbent, various properties are greatly enhanced, especially compressive strength and resistance to liquid water soaking properties to achieve a high level, as long as there is no “renewable energy consumption” and other operations do not appear Factors, the activated alumina treatment, the compressed air dew point stable to -40 ℃ in the technology is guaranteed, and life expectancy of up to 2-3 years.
activated alumina desiccant in air dryer
Compressed air from the compressor at the rear of the compressor is a type of supersaturated compressed air containing a certain amount of condensate. A small amount of condensate has little effect on the dryer. If there is no gas-water separator and filter installed in front of the dryer or a large amount of condensed water enters the adsorption tower due to improper factors, the adsorption will deteriorate and the temperature of the dew point rises sharply In severe cases, the adsorbent breaks down into powder, which is manifested by the powder sprayed from the muffler and the clogging of the rear dust filter, and the consequence of having to change the adsorbent. This is because: a large number of condensed water into the adsorption tower, the adsorbent in a moment to absorb a lot of water, while releasing a lot of heat of adsorption, because the adsorbent is a non-thermal conductor, adsorption heat can not be distributed in time by the adsorbent microporous liquid water Absorption, when the heat is sufficient, the water evaporates into gas after the rapid expansion of the volume swell the adsorbent. Therefore, it is absolutely necessary to dispose the water separation equipment in front of the adsorption dryer.
