Waste refrigerator thermal insulation material recycling method and filter residue recycling method thereof

The invention discloses a waste refrigerator thermal insulation material recycling method and a filter residue recycling treatment method thereof. The waste refrigerator thermal insulation material recycling method specifically comprises the steps of pretreatment, component analysis, alcoholysis, neutralization, coarse filtration, refining, fine filtration and product obtaining. The filter residue recovery treatment method comprises the following steps: collecting filter residues, washing, filtering and flushing, distilling, and recovering a detergent and a product. According to the recycling method of the waste refrigerator heat preservation material and the filter residue recycling treatment method of the waste refrigerator heat preservation material, the influence of impurities on the recycling process is effectively reduced, incomplete reaction or generation of excessive by-products is avoided, the product yield is increased, generation of three wastes is reduced, and the recycling method and the filter r
