Abstract

The invention discloses an under-pressure oxygen-enriched circulating fluidized bed gasification process method and system. The system comprises a feed coal bunker, a screw feeder, a pressurized oxygen-enriched circulating fluidized bed gasifier and a deslagging belt, wherein the feed coal bunker is connected with a coal washer; a slag lock hopper is connected with a roller slag cooler; the deslagging belt is arranged beside the roller slag cooler; the top of a high-temperature cyclone separator is connected with the top of a gasifying agent preheater, the gasifying agent preheater is connected with a steam superheater, an economizer is connected with a cyclone dust collector, the cyclone dust collector is connected with a high-temperature filter body, and the high-temperature filter bodyis connected with a humidifying dust removal tower. According to the under-pressure oxygen-enriched circulating fluidized bed gasification process method and system, a novel structural design is adopted, so that the process flow is simple, the gasification pressure is easy to improve, the system operation cost and the investment cost are low, the dust removal efficiency is high, and the content ofwater vapor in produced coal gas is high.

Description

technical field [0001] The invention relates to the technical field of fuel coal gasification equipment, in particular to a pressurized oxygen-enriched circulating fluidized bed gasification process method and system. Background technique [0002] Fuel coal gasification equipment is a device that reacts coal, coke, semi-coke and other solid fuels with gasification agents under high temperature, normal pressure or pressurized conditions, and converts them into gas products and a small amount of residue. By adding gasification agents, the gasification Gasification reaction between agent and fuel to obtain coal gas with less impurities. At present, the commonly used coal gasification equipment for fuel is circulating fluidized bed. , has been widely used in coal gasification and boiler fields, especially suitable for the utilization of low-quality coal in our country. [0003] During the continuous use of circulating fluidized bed and supporting production system, the followin...
