AI Technical Summary
Existing backfire prevention and flame arrestor devices will cause the flame arrestor core to deform and allow flame penetration when the exhaust gas temperature exceeds the metal's temperature resistance limit. Furthermore, they fail to effectively utilize the heat generated by incineration exhaust gas, resulting in energy waste.
A combination of honeycomb ceramics and sintered metal mesh is used as a fire barrier. The ceramic spiral extends the airflow path and disrupts the flame structure. Heat is recovered by combining heat pipes and a water tank system. The ceramic fan blades driven by a motor remove carbon deposits and extinguish the flame, thereby improving the high-temperature resistance and energy efficiency of the device.
It effectively prevents flame penetration, improves the applicability and safety of the device, and recovers the heat generated by incineration exhaust gas, reducing energy waste, extending the life of the device and protecting the safety of personnel.
