Description
Technical field
The present invention relates to a kind of coal gasifier, particularly a kind of deflector type coal gasification apparatus.
Background technology
Gasification is one of China's clean coal technology important composition, and it not only can improve current efficiency of energy utilization, can reduce the generation of pollution simultaneously effectively.Efficiency of carbon conversion is one of important indicator of reflection gasification effect, and the principal element that influences efficiency of carbon conversion has raw material activity, gasification temperature, the residence time and carbon oxygen mixture strength etc.Usually, coal for gasification just determines in planning in early stage of projects, and is less by changing the possibility that active more excellent raw material improves efficiency of carbon conversion, therefore changes raw material and improves efficiency of carbon conversion and generally do not considered; Gasification temperature need be taken all factors into consideration multiple factors such as gasification efficiency, slag, device security, and variable range is more less, therefore improves efficiency of carbon conversion by the change gasification temperature and is not also considered.In sum, increase the mixture strength between the reaction mass residence time and the strength imparting material, also just become the key factor that influences efficiency of carbon conversion.What the texaco coal-water slurry gasification stove adopted is single nozzle top spray mode, because its service temperature is low, the material stroke and the residence time are shorter, efficiency of carbon conversion generally has only about 95%, gasification is not high to the utilization ratio of carbon, has caused the waste of carbon, does not meet the requirement of energy usury with efficient.
Summary of the invention
Goal of the invention of the present invention is: at the problem of above-mentioned existence, a kind of simple in structure, easy to operate, baffling shape flame vapourizing furnace that efficiency of carbon conversion is high is provided, long at this vapourizing furnace internal reaction residence time of material, sufficient reacting is strengthened in the disturbance of material, mixture strength height between the material, the efficiency of carbon conversion height.
