Abstract

The invention provides a comprehensive utilization method for organic resin wastes. The method comprises the following steps: (1) mixing the pretreated organic resin wastes with water and auxiliaries,and carrying out slurrying to obtain a slurrying liquid; (2) mixing the slurrying liquid with a carbon-derived substance to prepare water coal slurry; (3) carrying out a gasification reaction on thewater coal slurry at an oxygen-containing atmosphere, the temperature 1100-1600 DEG C and the pressure of 0.5-4.0MPa to obtain a gaseous product and liquid molten slag; and (4) carrying out shock chilling separation on the gaseous product and the liquid molten slag to obtain a mixed gas and glass-state residues. According to the comprehensive utilization method, a water coal slurry gasification technology is applied to the fields of waste treatment and utilization, organic components in the organic resin wastes are gasified at high temperature within short time and are converted into the gaseous product which can be comprehensively utilized, and toxic and harmful substances such as trace heavy metals are fixed in the glass-state residues, so that not only is the aim of harmless treatment of the organic resin wastes achieved, but also the comprehensive utilization of the organic resin wastes can be realized.

Description

technical field [0001] The invention belongs to the field of harmless disposal and comprehensive utilization of industrial solid waste, and relates to a comprehensive utilization method of organic resin waste, in particular to a comprehensive utilization of organic resin waste produced in industries such as electric power, chemical industry, metallurgy and pharmacy method. Background technique [0002] In the water treatment of industries such as electric power, metallurgy and chemical industry, ion-exchange organic resins are often used, so a large amount of non-ionic organic resins will be produced. Because it adsorbs heavy metal ions or organic matter, it has long-term potential danger, and if it enters the environment, it will cause serious pollution. Organic resin waste is clearly included in the "National Hazardous Waste List" (2016 Edition), and the state has strict regulations on its disposal and utilization. [0003] The existing organic resin waste treatment meth...
