Low-temperature oxygen-free pyrolysis process for organic hazardous waste

Abstract

The invention discloses a low-temperature oxygen-free pyrolysis process for organic hazardous waste. The process includes, firstly, entering, by materials, a carbonizer after pretreatment, and adjusting the distribution of the materials in the carbonizer; gradually heating the materials in the carbonizer by a combustion chamber; entering, by pyrolysis gas generated by pyrolysis of the materials, agas distribution bag; after cooling and water washing, combusting the pyrolyzed materials in a hearth to become carbon slag; finally, until no pyrolysis gas is generated in the carbonizer, stopping heating, and after the carbonizer is gradually cooled down, discharging the carbon residue. The organic hazardous waste material is treated by the low-temperature anaerobic pyrolysis process of the organic hazardous waste, so that the harmless treatment efficiency of the hazardous waste and the added value of the low-temperature anaerobic pyrolysis recovery product can be improved, the defects in the existing technical field of organic hazardous waste treatment are made up, and the organic hazardous waste pyrolysis process with safety, environmental protection, good carbonization effect and high carbonization efficiency is provided.

Description

technical field [0001] The invention relates to the technical field of organic hazardous waste treatment, in particular to a low-temperature anaerobic pyrolysis process for organic hazardous waste. This process can dispose of pharmaceutical waste (HW02), waste medicine, medicine (HW03), pesticide waste (HW04), wood preservative waste ( HW05), waste organic solvent and waste containing organic solvent (HW06), waste mineral oil and waste containing mineral oil (HW08), oil / water, hydrocarbon / water mixture or emulsion (HW09), distillation residue (HW11) ), manufacturing of coatings, inks, pigments and similar products (HW12), organic resin waste (HW13), photosensitive material waste (HW16), phenol-containing waste (HW39), ether-containing waste (HW40), organic halide waste (HW45 ), other wastes (HW49), catalyst wastes (HW50) and other organic hazardous wastes. Background technique [0002] Hazardous organic waste refers to waste with hazardous characteristics that is included ...

AI Technical Summary

Problems solved by technology

[0003] Organic hazardous waste must be handled safely and properly because it will have a serious impact on the environment and even the human body. At present, the facilities for organic hazardous waste treatment mainly include crushers, feeders, carbonization furnaces, cooling pools, oil-water separators, and cyclone dust collectors. Machines, alkali cleaning equipment, UV purification equipment, etc., but when the existing carbonization furnace carbonizes organic hazardous waste at high temperature, the organic hazardous waste will adhere to the bottom of the carbonization furnace, which will affect the carbonization effect and lead to low carbonization efficiency
