AI Technical Summary
Existing waste gas purification devices for compound fertilizer granulation are prone to generating bubbles when the gas enters the purification liquid, which reduces the gas-liquid contact efficiency and affects the purification efficiency.
The device employs a corrugated plate and needle structure, combined with a motor-driven cam system. The striking block drives the plate and needle to reciprocate, puncturing air bubbles. The hollow column and spring also cause the purified liquid to vibrate, increasing the gas-liquid contact area and time.
It improves gas-liquid contact efficiency, enhances waste gas purification efficiency, and strengthens purification effect.
