Embodiment Construction

[0022] The invention adopts an oxygen-free catalytic pyrolysis resource utilization technology of waste batteries. This technology is a process in which an organic solid waste is heated and decomposed into organic matter under anaerobic conditions, so that the metal is separated without damage, and the complex organic matter is turned into a small molecule gas and used as a regenerative fuel. A very small amount of harmful substances, For example, fluoride is stabilized into a salt to be regenerated. The anaerobic pyrolysis process is a complex chemical reaction reduction process, including: bond breaking of macromolecules, isomerization and polymerization of small molecules, and finally generates various smaller molecules, mainly including:

[0023] (1) Combustible gases mainly composed of low-molecular hydrocarbons such as hydrogen, carbon monoxide, and methane;

[0024] (2) Organic compounds including acetone acetate and other compounds that are liquid at normal temperatur...

Abstract

The invention relates to anaerobic catalytic thermal cracking system and method for waste batteries. The system comprises a lifter, a flow stabilizing bin communicated to an outlet of the lifter, double pneumatic gate valves arranged at the outlet of the flow stabilizing bin, a drying tower arranged below the flow stabilizing bin, a wind blockage valve arranged at an outlet of the drying tower, atubular spiral conveyor communicated to the outlet of the drying tower, a disc feeder arranged below an outlet of the tubular spiral conveyor, a crusher communicated to an outlet of the disc feeder, avalve inserting plate arranged at an outlet of the crusher, a spiral conveyor arranged below the crusher, a charge and discharge barrel communicated to an outlet of the spiral conveyor, a double-drumrotary kiln communicated to an upper transverse hole of the charge and discharge barrel, and a combustion furnace sleeving the double-drum rotary kiln, wherein a lower transverse outlet of the chargeand discharge barrel is communicated to an outlet of the double-drum rotary kiln, and the lower end of the charge and discharge barrel is successively communicated to an unloader and a vertical tubular spiral conveyor. The system provided by the invention can achieve harmless recycling treatment of waste batteries, and is high in degree of automation. Without inert gas protection, the process isfree of secondary pollutant generation or emission.

Description

technical field [0001] The invention relates to a process method and a system for recycling waste batteries, and in particular to a system and a method for treating a large number of waste lithium batteries through anaerobic pyrolysis to achieve resource utilization and harmless discharge. Background technique [0002] Human activities will inevitably produce all kinds of waste, including domestic waste, industrial waste, agricultural and forestry waste, electronic waste, medical waste and so on. With the rapid development of the electronics industry, the application of a large number of batteries, especially the large-scale application of power lithium batteries, will eventually form waste or garbage. The impact on human health and the environment cannot be ignored, and it also wastes a lot of precious resources. , such as battery materials, including various metal and non-metal materials. [0003] The massive generation of electronic waste and the imperfect treatment tech...
