Fixed bed coal gasification furnace, fixed bed coal gasification and coal gasification hydrogen production system and process method

Abstract

The invention relates to a coal gasification and coal gasification hydrogen production equipment system and process, and in particular, relates to a fixed bed gasification furnace, a coal gasificationand coal gasification hydrogen production system and process method. The gasification furnace comprises a furnace body, the furnace body is provided with a plurality of side-by-side gasification chambers, gasification agents generated by a gasification agent generation device are directly fed into the gasification chambers through gasification agent channels in the left side walls and the right side walls of the gasification chambers and gas distribution holes evenly formed in the inner side walls, and coal materials in the gasification chambers make contact with high-temperature gasificationagents to achieve gasification. The fixed bed gasification furnace composed of the plurality of coal gasification chambers and a double-gas-collecting-pipe network form the coal gasification system,efficient coal gasification and effective separation are achieved through coordination and time-phased coal gasification process control, the relative proportion and purity of hydrogen and other maincomponents in coal gas are improved, and coal gasification, coal gasification hydrogen production and other product production are completed. The fixed bed gasification furnace, the coal gasificationand coal gasification hydrogen production system and the process method are high in efficiency and low in energy consumption, and efficient coal gasification and coal gasification hydrogen productionare achieved.

Description

technical field [0001] The invention relates to coal gasification equipment and technology, in particular to a fixed bed coal gasification furnace, a fixed bed coal gasification and coal gasification hydrogen production system and a process method. Background technique [0002] my country's natural resource structure, which is short of oil, gas, and relatively rich in coal resources, determines the long-term importance of my country's energy structure and coal in industry and economy. How to cleanly utilize my country's relatively abundant coal resources, improve my country's energy and industrial technology level and develop coal chemical industry has become a major development direction of national energy and resource utilization. Coal gasification and synthesis gas production are inseparable from various scales of high energy consumption industrial production and coal chemical process. Coal gasification is the main way and necessary means to realize clean and efficient ut...
