Abstract

The invention relates to a process for co-processing organic waste liquid by an oxygen-enriched side-blown molten pool smelting furnace, which comprises the following steps: while solid hazardous waste is processed by the oxygen-enriched side-blown molten pool smelting furnace, the organic waste liquid is incinerated, combustible components are incinerated to generate carbon dioxide and water, and the carbon dioxide and the water enter a flue gas processing process link along with main flue gas of the oxygen-enriched side-blown molten pool smelting furnace; selectively treated organic waste liquid not only contains high-calorific-value organic waste liquid, but also can be synchronously treated after compatibility, and oxygen-enriched air is added into a molten pool, so that the organic waste liquid is intensively combusted, and combustion heat release of the organic waste liquid is effectively utilized; organic waste liquid is matched and reasonably matched with a reducing agent, so that the temperature of a molten pool is kept in a stable interval, and the stable smelting process is ensured; meanwhile, if heavy metal is contained in the organic waste liquid, the organic waste liquid can be oxidized in the smelting process of the molten pool to enter a slag phase, general solid waste water quenched slag is formed after water quenching, and therefore recycling and harmless treatment of the organic waste liquid in the smelting process of the oxygen-enriched side-blown molten pool is achieved.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a process for co-processing organic waste liquid with an oxygen-enriched side-blown molten pool smelting furnace. Background technique [0002] Organic waste liquid refers to waste mineral oil or waste liquid containing waste mineral oil with different calorific values, waste organic solvent, oil-water or hydrocarbon-water mixture or emulsion, and waste containing organic halides and other types of hazardous waste. [0003] The composition of organic waste liquid is complex, the calorific value varies greatly, and it contains elements such as C, H, S, N, and heavy metals. The organic waste liquid listed as hazardous waste in the national hazardous waste list must be disposed of in an environmentally friendly manner, otherwise it will cause harm to the environment. Secondary pollution. [0004] There are many types of organic waste liquids, large quantities, and different ...
