Desiccant dryers utilize adsorbents such as activated alumina, molecular sieves, or silica gel to remove moisture through their porous structures. The performance of the adsorbent directly impacts drying efficiency. Over time, with adsorption-regeneration cycles, the adsorption capacity degrades and must be periodically replaced to ensure stable system operation.
The typical replacement cycle is every 3–5 years, but should be adjusted based on the following factors:
1. Usage Frequency: Frequent use accelerates adsorbent saturation, shortening the cycle.
2. Ambient Humidity: Higher inlet humidity increases the adsorption load and reduces service life.
3. Operating Parameters: Abnormal pressure or elevated dew point may indicate adsorbent failure.
4. Load Fluctuations: Long-term high-load operation accelerates performance decline.
5. Environmental Conditions: Harsh environments like high temperature and heavy dust may require earlier replacement.
Key precautions:
1. Monitoring Indicators: Regularly check the outlet dew point. If it remains above normal, inspect the adsorbent status.
2. Replacement Procedure: Fully clean the adsorption tower before refilling. Avoid mixing new and old adsorbents. Fill evenly and compact to prevent air channeling.
3. Product Matching: The new adsorbent must match the original model, with consistent porosity and mechanical strength.
4. Regeneration Check: After replacement, verify regeneration effectiveness, including heating temperature and cooling time.
When deciding whether to replace the adsorbent, balance replacement cost with operating cost. Delaying replacement may lead to system performance degradation, increased energy consumption, and lower production efficiency.
