AI Technical Summary
Lime powder is prone to moisture and blockage in the feed pipe, and there is a lack of effective cleaning methods, resulting in frequent pipe blockages, which affects the stable operation of equipment and the health of operators.
A jacketed pipe is installed outside the lime feed pipe to form an annular cavity. Combined with the ash cleaning mechanism, compressed air and flushing water are used to achieve automated cleaning, preventing lime powder from caking and clogging.
Through physical isolation and automated cleaning mechanisms, blockages are significantly reduced, improving the operating efficiency and reliability of the lime slurry preparation system and reducing downtime maintenance requirements.
