A kind of processing technology of waste picric acid

Abstract

A process for treating waste picric acid, comprising the following steps: 1) putting acetone reagent into a sample bottle for standby; 2) adding waste picric acid into the sample bottle in step 1) for dissolution; 3) putting the waste picric acid in step 2) The sample bottle is sealed and packed, and then sent to the rotary kiln incineration system for incineration; the sample bottle is a combustible sample bottle. The overall process combination of the present invention can ensure the full combustion of picric acid, and at the same time ensure that the picric acid will not cause heat load shock and pressure shock to the rotary kiln incineration system after the feeding of picric acid during the combustion process, and ensure the safety of operation, suitable for picric acid Industrial processing of harmless treatment.

Description

technical field [0001] The invention relates to the technical field of hazardous waste treatment, in particular to a process for treating waste picric acid. Background technique [0002] Picric acid has the following characteristics and properties: Picric acid, also known as 2,4,6-trinitrophenol, is a kind of explosive, abbreviated as TNP and PA, and its pure substance is slightly yellow crystal at room temperature. Trinitro-substitutes, affected by the electron-withdrawing effect of nitro, have strong acidity and strong bitter taste. Picric acid is insoluble in carbon tetrachloride, slightly soluble in carbon disulfide, and easily soluble in hot water, ethanol, ether , easily soluble in acetone, benzene and other organic solvents, taboo oxidants, alkalis, heavy metal powders, picric acid can be used in explosives, dye industries, and research in various scientific research institutes or colleges and universities, and there are more picric acid wastes produced every year Ho...

[0002] Picric acid has the following characteristics and properties: Picric acid, also known as 2,4,6-trinitrophenol, is a kind of explosive, abbreviated as TNP and PA, and its pure substance is slightly yellow crystal at room temperature. Trinitro-substitutes, affected by the electron-withdrawing effect of nitro, have strong acidity and strong bitter taste. Picric acid is insoluble in carbon tetrachloride, slightly soluble in carbon disulfide, and easily soluble in hot water, ethanol, ether , easily soluble in acetone, benzene and other organic solvents, taboo oxidants, alkalis, heavy metal powders, picric acid can be used in explosives, dye industries, and research in various scientific research institutes or colleges and universities, and there are more picric acid wastes produced every year However, compared with general waste hazardous chemicals, picric acid has a high risk of safe disposal due to its explosiveness. Currently, picric acid treatment methods include adsorption and catalytic degradation methods for picric acid wastewater. In the process of treatment, the production process is complicated, the production cost is high, and it is difficult to realize industrial promotion and processing, and the adsorbent after adsorption needs to be further processed, otherwise it will also pollute the environment and cannot achieve true harmless treatment. There is no relevant report on the treatment process of picric acid solid waste
