Abstract

The invention discloses a device for producing semi water gas by utilizing oxygen-enriched air, which is characterized in that: the input of the gas making furnace is connected with the output of the air mixing tank, input of the air mixing tank is connected with ordinary windpipes, the other end of the air mixing tank is connected with the output of the oxygen-enriched generator and the input of the generator is connected with the blower. The device for producing semi water gas by utilizing oxygen-enriched air has the advantages that: by increasing the oxygen concentration of the input gas, the gasification decomposing temperature in the gasification furnace, the steaming decomposition efficiency and the water gas yield can be increased, while the coal consumption and the steam consumption are reduced; meanwhile, the device does not change the original gas making system and the one-time investment is saved. The device and the method are in particular suitable for the retrofit of the gas making furnaces for existing chemical fertilizer industry.

Description

Technical field: [0001] The invention relates to a device and method for producing semi-water gas, in particular to a device and method for producing semi-water gas by using oxygen-enriched air, so as to improve the gasification efficiency of fixed-bed gas-making furnaces in the chemical fertilizer industry. Background technique: [0002] At present, most of the existing small nitrogen fertilizer plants in the country use solid anthracite lumps in fixed-bed gas-making furnaces to gasify the raw material gas of ammonia in intermittent gasification. During the gas production process, in the gas production stage and the recovery stage, ordinary air with an oxygen content of ≤21% is added to the gas furnace for gas production, and nitrogen air is added in the up and down gas production process and the recovery process (CO+H / N 2 ) is mixed at a ratio of 3 to 3.3, and its gas production is closely related to the oxygen content in the furnace air. The air is intermittently gasif...
