Resin-based composite material waste efficient recovery system and method thereof

Abstract

The invention discloses an efficient recovery system and method for resin-based composite waste, and relates to the technical field of carbon fiber recovery equipment. The carbon fiber resin composite material is fixed on a bracket by a supporting partition plate and is fed into a heating furnace tube. Argon is introduced after vacuumizing, the microwave generator is started, and the materials are heated to be cracked. And after the cracking reaction is finished, introducing air / oxygen, starting an electric heating tube, and carrying out oxidation carbon removal treatment on the cracked product to efficiently recover the carbon fiber. And the generated liquid is collected in the collecting crucible and then flows into the collecting and separating system. Generated high-temperature gas is exhausted through an exhaust port and enters a waste heat recovery system, heat is conducted to n-pentane in a heat exchange pipeline, n-pentane is gasified to drive turbine blades to rotate to generate electricity, and the high-temperature gas after heat exchange flows into a collection and separation system after being condensed. The heating temperature interval of the heating furnace cavity is controlled according to the boiling point difference of the cracked liquid product, and the condensed liquid is heated, gasified and collected into different collecting boxes.

Description

technical field [0001] The invention relates to the technical field of carbon fiber recycling equipment, in particular to a system and a method for efficient recycling of resin-based composite material wastes. Background technique [0002] In recent years, due to the high specific strength, high specific modulus, high toughness and excellent X-ray transmission performance of carbon fiber, its demand has increased year by year. When widely used in aerospace, automobile, medical and other fields, it can achieve weight reduction, Impact resistance, fatigue resistance and other application effects. The extensive use of carbon fiber resin composite components will bring a large amount of carbon fiber composite material waste after their service life, resulting in serious waste of resources and environmental pollution. At present, carbon fiber composite materials in the market are mainly based on carbon fiber reinforced thermosetting resins. After the thermosetting resin matrix i...
