There may be several reasons for the breakage of activated alumina ball in the dryer.
The adsorption tower of the adsorption dryer is not tightly packed with activated alumina &molecular sieves. It results in a large amount of compression and subsequent breakage during operation.
The intake temperature of the adsorption dryer is too high, which can damage the service life and effectiveness of the activated alumina ball and molecular sieve adsorbents.
A lot of oil or liquid water enters the adsorption tower. This can cause poisoning of activated alumina balls, loss of adsorption ability, or adsorption failure and dew point temperature rise. Long term exposure to high pressure can cause pulverization and fragmentation.
The quality of activated alumina is important
The quality of activated alumina balls is poor, with problems such as low strength, soft water expansion, and small specific surface area. Under the action of airflow, they wear down. The adsorption area decreases, the water absorption efficiency decreases. But the dew point increases.
Therefore, in order to reduce the breakage of activated alumina in the dryer, a series of preventive measures need to be taken. It includes selecting high-quality activated alumina balls, controlling the inlet temperature. Avoiding the entry of oil and liquid water, and ensuring tight packing of the adsorption tower. Pingxiang Zhongci activated alumina (taking commonly used specifications of 3-5mm as an example) has a compressive strength of over 180N/particle, a specific surface area of 300-380 ㎡/g, and a static adsorption capacity of over 18%. All other indicators fully meet or exceed the current implementation standards. At present, we have established good cooperation platforms with numerous user units, air separation equipment manufacturers, regional distributors, etc.
