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

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0024] The quality of solid carbon residue obtained by low-temperature pyrolysis of organic hazardous waste varies with the properties of materials. According to the properties of materials, two parts of organic hazardous waste pyrolysis production lines are set up, one part of organic hazardous waste pyrolysis production line is used for waste salt disposal, and the other part is organic The hazardous waste pyrolysis production line is used for the disposal of other organic wastes.

[0025] as attached figure 1 As shown, a low-temperature anaerobic pyrolysis process for organic hazardous waste specifically includes the following steps:

[0026] S1, the material ent...

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.
