Embodiment 1

[0052] Such as Figure 1-Figure 2 As shown, a slag gasification reaction furnace for preparing carbon monoxide includes a gasification furnace body 24, a slag port 8, a combustion nipple 6, a quench chamber 4 and an automatic coking machine 17;

[0053] The gasification furnace body 24 includes: a shell 12, an upper cylinder body 13, a furnace inlet 16, a gas outlet 20, a lining refractory brick 14, a water jacket 11, a gasification agent nozzle 10, a water cooling coil 25, a melting Slag pool 9, furnace cover 15 and connecting large flange 21;

[0054] The furnace inlet 16 is connected to the lower distributor flange 19 of the automatic coking machine 17;

[0055] The furnace cover 15 is connected to the upper cylinder body 13, and the gas outlet 20 is located on the furnace cover 15;

[0056] The upper cylinder 13 is connected to the slag pool 9 with a large flange 21;

[0057] The gasifying agent nozzle 10 is connected to the molten slag pool 9;

[0058] The slag port 8...

Embodiment 2

[0073] A new gas production method using a slag gasification reaction furnace to prepare carbon monoxide. The high-temperature coal gas generated in the lower part of the slag gasification reaction furnace is in countercurrent contact with the raw materials from the furnace inlet 16. The temperature in the drying area is less than 500 ° C. The raw material is heated and dried by the hot gas, and the water is removed here. The dried carbon layer continues to move down and enters the carbonization zone at 500-900°C. After the gas undergoes a series of equilibrium endothermic reactions, the crude gas is cooled, and the raw material is partially gasified. At the same time, the temperature of the raw material rises and enters the combustion zone, and the mixed gaseous CO 2 Oxygen and gas enter the bottom of the gasifier with a high-speed airflow through the gasification agent nozzle 10. The oxygen reacts quickly with the coal in the combustion zone and releases a large amount of hea...

Description

technical field [0001] The invention relates to a slag gasification reaction furnace for preparing carbon monoxide and a gas production method thereof, which belongs to the fields of coal chemical industry, coke (including semi-coke) gasification, gas, etc., and involves chemical engineering, chemical technology, chemical machinery, instruments and automation technology. Background technique [0002] The traditional fixed-bed batch gasifier (UGI) adopts the solid-state slagging method, which is still in operation in my country’s nitrogen fertilizer production, but it is increasingly inconsistent in terms of single furnace processing capacity, operating cost, coal adaptability, energy efficiency and environmental protection. Industry development needs; fixed-bed pure oxygen continuous gasification also adopts solid-state slag discharge method. Although it has brought some breakthroughs to the development of fixed-bed technology, it also needs to further increase the pyrolysis ...
