AI Technical Summary
Right-angle bends in ash conveying pipelines can easily obstruct and block the flow of ash particles, and are prone to leakage and blockage after long-term operation. Existing technology can only clear blockages after they occur, and cannot effectively prevent blockages.
The economizer ash conveying pipeline anti-clogging device adopts a three-way structure. It uses a fan to ventilate the pipeline and blow away particulate impurities attached to the corner of the three-way. The air nozzle and reflector bowl design blow up the settled particles. Combined with a one-way guide valve, it ensures stable flow rate and uses filter consumables to prevent impurities from entering.
It effectively prevents particles from clogging at bends, maintains stable pipe flow rate, and can clear blockages in a timely manner, reducing wear and leakage risks.
