Problems solved by technology

Therefore, it is necessary to treat the oil agent on the surface of waste silk with water and detergent. To clean one ton of waste silk, 5-10 tons of tap water is needed, and the water consumption is very large.
[0008] 2. The B value of the foam material product is high, the color turns yellow, and the quality is poor
[0010] 3. The degradation is serious, and the viscosity index of the foam material drops a lot
[0012] 4. Low added value of foam materials

Abstract

The invention discloses a method for recycling waste terylene fibers. The method comprises the following steps of primarily crushing the waste terylene fibers to obtain staple fiber pompons; purifying and degrading on the staple fiber pompons by dense microwave fields with high-frequency rotation; performing vacuum pumping on water and oil; finally, grinding and crushing to obtain finely-ground terephthalate (BHET) polymer powder; meanwhile, the invention provides a device system and microwave purifying equipment for realizing the method. The method, the device system and the microwave purifying equipment disclosed by the invention have the advantages that the waste terylene fibers are recycled by adopting microwave purification degradation to obtain the BHET polymer powder which can be used as the polyester raw materials; an original recovery mode of obtaining bubble powder is thoroughly changed, and closed circulating recovery of the waste terylene fibers is realized; the method is green and environment-friendly, high in economy and resource-saving; the device system and the equipment provide hardware guarantee for realizing the method.

Description

technical field [0001] The invention relates to a method for recycling and reusing polyester waste silk, and a device system and equipment thereof. Background technique [0002] Polyester waste silk is the industrial scrap produced in the production of polyester chemical fiber. It is an inevitable waste, and its production volume accounts for about 1-2% of the total output of the polyester industry. [0003] At present, a large amount of polyester waste silk is transported to some workshop-type enterprises. First, use water and detergent to treat the oil on the surface of the waste silk. To clean one ton of polyester waste silk, you need to use 5-10 tons of tap water. Then the cleaned polyester waste silk is centrifugally dehydrated, put into a foam material machine for friction granulation, and made into friction material (commonly known as foam material). The foam material machine is generally used for plastic chemical fiber (PP / PE plastic film, PET polyester waste silk,...
