Embodiment Construction
[0037] The present invention will be further described below in conjunction with the accompanying drawings.
[0038] Such as figure 1 , figure 2 Shown is a multi-stage gas distribution high-temperature coal gasification device, including a gasification reactor 1 and an air chamber 100. The air chamber 100 is arranged at the bottom of the gasification reactor 1, and the gasification reactor 1 is divided from bottom to top. The oxygen-enriched combustion section 101, the mixed gasification section 102, the gasification heating section 103 and the gasification lifting section 104; The gasification heating section 103, the gasification heating section 103 shrinks upwards and transitions to the gasification lifting section 104;
[0039] The air chamber 100 is provided with an air chamber gasification agent inlet 2 and an air chamber slag discharge pipe 3;
[0040] The lower side of the oxygen-enriched combustion section 101 is provided with a primary feed port 151, a primary re...
