CARBONACEOUS SUBSTANCE REACTION SYSTEM AND METHOD |
摘要 |
A carbonaceous substance powder gasification system and gasification method. The system comprises a carbonaceous substance reaction apparatus and a gas return apparatus used for raising the pressure of some of a raw syngas cooled and preliminarily purified downstream of the reaction apparatus, then blending with high-temperature raw syngas upstream of the reaction apparatus and reducing the temperature. The method comprises reacting in a gasification reaction apparatus the carbonaceous substance and a gasification agent to generate raw syngas and ash and slag, some of the high-temperature raw syngas moving downstream with fly ash and liquid slag, and some of the high-temperature syngas moving upstream with fly ash; the downstream part of the high-temperature raw syngas being cooled, preliminarily purified and deslagged, then pressurized, and the wet raw syngas being injected into the system and blended with the upstream high-temperature raw syngas; the remainder of the high-temperature syngas moving upstream with fly ash and blending and cooling with the low-temperature wet syngas injected by the preliminary cooler, and optionally being entered into the cooling reaction stage; the cooled or cooling-reacted raw syngas continuing upstream, passing through the upper cooling stage and cooling again and ash being removed to obtain the raw syngas. |
