[0017] In this embodiment, the combustion equipment interface 2 at the inlet end of the incinerator body 1 and the waste heat recovery equipment interface 6 at the outlet end are respectively connected to the combustion equipment and the waste heat recovery equipment through flange interfaces, and the incinerator body 1 is connected to the porous uniform annular cavity air interface 3 and the porous uniform semi-annular cavity exhaust gas inlet 3 through flange interfaces. In order to protect the safety of the equipment under high-temperature incineration, the high-strength high-temperature resistant refractory lining 8 is connected and fixed to the incinerator body 1 through high-temperature resistant lining claws 9 to form a whole.

[0018] Working principle: The combustion equipment connected to the combustion equipment interface 2 at the inlet end of the incinerator body 1 sends the high-temperature flue gas of about 1500℃ after the combustion of fuel gas and combustion-supporting materials into the incinerator. After mixing with the air sent in by the porous uniform annular cavity air interface 3, the temperature drops to about 1000℃ required for incineration, and the uniformity of the high-temperature flue gas is guaranteed. The tail gas entering the incinerator from the porous uniform semi-annular cavity tail gas interface 5 is incinerated by high-temperature flue gas for 1-2s, and after being evenly distributed in the furnace through the flue gas distributor 10, it enters the waste heat recovery equipment through the outlet end waste heat recovery equipment interface 6 for waste heat recovery.
