Embodiment Construction
[0017] Domestic garbage that has been pre-treated enters the gasifier 1 through the conveying device. During the material descending process, the air blown in by the blower and the high-temperature gas formed after heat exchange in the heat exchanger 3 enter through the gas mixer 4 inlet. After being mixed with the steam generated by the steam generator 5 in the gas mixer 4, it enters the gasifier 1 under the action of the fan, and in the gasification gas, the gasification agent interacts with domestic waste, and reacts in a high temperature environment to form coarse The fuel gas passes through the gas outlet of the gasifier, and passes through the gas purification and washing system 2 under the action of the fan to produce clean syngas for resource utilization.
[0018] In the gasification layer of the gasifier 1, the oxygen in the air and the materials are combusted to generate carbon dioxide, which releases a large amount of heat. Then, under the action of high temperature ...
