Abstract

The invention relates to a harmless treatment device for high-sulfur-chlorine high-risk hazardous waste. The harmless treatment device comprises a dissolving and diluting tank, a sealing cover and a tail gas treatment assembly. The sealing cover is arranged on the periphery of the dissolving and diluting tank, and an air suction pipeline is arranged on the sealing cover. The tail gas treatment assembly is connected to the air suction pipeline. The invention further provides a harmless treatment method for the high-sulfur-chlorine high-risk hazardous waste. The harmless treatment method comprises the steps that S1, the hazardous waste is dissolved in one of water, sodium hydroxide, glacial acetic acid and ethyl alcohol; and S2, absorption treatment on tail gas generated after dissolution. Distillation residue hazardous waste is dissolved in one of water, sodium hydroxide, glacial acetic acid and ethanol in advance, tail gas generated after dissolution is absorbed, and therefore distillation residues are subjected to harmless treatment, and the treatment risk is reduced.

Description

technical field [0001] The invention belongs to the field of harmless disposal of hazardous waste, in particular to a device for harmless disposal of high-sulfur and high-risk hazardous waste. Background technique [0002] The 2021 version of the "Inventory of Hazardous Wastes" clearly stipulates that solid wastes (including liquid wastes) that fall under any of the following conditions shall be included in this inventory: [0003] (1) Having one or more hazardous properties of toxicity, corrosiveness, flammability, reactivity or infectivity. [0004] (2) It is not ruled out that it has hazardous characteristics, may cause harmful effects on the ecological environment or human health, and needs to be managed as hazardous waste. [0005] The distillation residue belongs to the HW11 category of the "Hazardous Waste List", which mainly comes from the production fields of dyestuffs, medicines, and pesticides. Distillation residue has no reuse value and has harmful and dangerou...
