AI Technical Summary
In high-temperature environments, electric or pneumatic valves are at high risk of sealing failure, which can lead to external air entering the pyrolysis unit, affecting product quality and causing safety accidents. Existing sealing devices are prone to aging, deformation or damage at high temperatures, and tar can easily stick together, causing valves to jam or not close properly.
It adopts a purely mechanical automatic sealing structure, which achieves automatic sealing and discharge by using a spring-driven valve plate and an eccentric rotation design, combined with the material's own gravity and torsion spring reset; it is equipped with a multi-stage heat recovery unit and inert gas pretreatment, which uses waste heat to preheat the material and purify the gas, and the annular purge pipe self-cleanes the valve plate; non-condensable gases are used for combustion heating and sealing purging.
It achieves reliable and safe sealing at high temperatures, reduces the risk of equipment failure, improves system operating efficiency and energy utilization, avoids the risk of high-temperature seal failure and explosion, and ensures the stability of the oxygen-free environment and product quality.
