Abstract
The invention discloses a green high-valued regeneration method of polyester waste plastics, which comprises the following steps: step A1: sorting the collected polyester plastic bottles on a sorting platform by a color sorter to separate bottles with different colors; step A2: performing label-removing crushing treatment on the plastic bottle by using a label-removing crushing system; step A3: separating the bottle cap and the bottle body of the crushed plastic bottle; according to the automatic label paper briquetting and packaging device, the plastic bottles are crushed by the crushing box to be changed into plastic bottle pieces and label paper pieces, the label paper pieces are sucked into the briquetting chamber through the exhaust fan, and then are subjected to briquetting treatment through the briquetting cylinder, so that efficient automatic label paper briquetting and packaging work is realized, the manpower labor is reduced, the treatment efficiency is improved, the device simultaneously achieves the purpose of crushing, the subsequent bottle piece crushing process is not needed, the subsequent process steps are reduced, the time for recycling and treating the whole plastic bottles is saved, and the production efficiency is improved.
Description
Technical Field
The invention belongs to the technical field, and particularly relates to a polyester waste plastic green high-valued regeneration method and a regeneration system.
Background
The plastic bottle is mainly made of polyethylene or polypropylene and other materials with a plurality of organic solvents. The plastic bottle widely uses Polyester (PET), Polyethylene (PE) and polypropylene (PP) as raw materials, and is a plastic container which is added with a corresponding organic solvent, heated at high temperature, blown, extruded and blown or injection molded by a plastic mold. The packaging container is mainly used for liquid or solid disposable plastic packaging containers of beverages, foods, pickles, honey, dried fruits, edible oil, agricultural and veterinary medicines and the like. The plastic bottle has the characteristics of low breakage probability, low cost, high transparency, food-grade raw materials and the like.
After the waste plastic packing materials enter the environment, the waste plastic packing materials are difficult to degrade, so that the long-term deep ecological environment problem is caused. Firstly, the waste plastic wrappage is mixed in soil to influence crops to absorb nutrients and moisture, so that the yield of the crops is reduced; second, the waste plastic packages discarded on land or in water are swallowed by animals as food, resulting in the death of the animals (in zoos, pastures and oceans, such a situation is common); thirdly, the waste plastic packages mixed in the domestic garbage are difficult to treat: land will be occupied for a long time in landfill treatment, the domestic garbage mixed with plastics is not suitable for composting treatment, and the sorted waste plastics are difficult to recycle due to the fact that the quality cannot be guaranteed.
Therefore, the waste plastic bottles are required to be timely recycled before being thrown as garbage, the phenomenon that the waste plastic bottles are discarded at will to pollute the environment and how to recycle the waste plastic bottles is a big problem to be solved for plastic products.
Disclosure of Invention
The invention provides a green high-valued regeneration method and a regeneration system for polyester waste plastics, which aim to solve the problem of low production efficiency in the background.
In order to achieve the purpose, the invention provides the following technical scheme: a green high-valued regeneration method of polyester waste plastics comprises the following steps:
step A1, sorting the collected polyester plastic bottles on a sorting platform by a color sorter, and separating bottles with various colors;
step A2, a label removing and crushing system is used for carrying out label removing and crushing treatment on the plastic bottle;
step A3, separating plastic bottle cover slip and plastic bottle pieces from the broken plastic bottle, and effectively separating the plastic bottle cover slip and the plastic bottle pieces by using a water tank;
step A4, cleaning the plastic bottle sheet;
step A5, putting the cleaned plastic bottle slices into a dryer for drying;
and A6, spreading the dried plastic bottle slices into a thin layer with the thickness of 0.5-1cm, irradiating by an ultraviolet lamp, and packaging and storing the plastic bottle slices irradiated by the ultraviolet lamp.
The step A4 comprises the following steps:
step B1, placing the broken plastic bottle pieces into a primary pretreatment tank, adding water into the pretreatment tank, and heating the temperature of the pretreatment tank to 90-100 ℃;
step B2, adding the plastic bottle pieces processed in the step B1 into a secondary processing pool, wherein a cleaning agent is added into the processing pool, and ultrasonic processing is assisted;
and step B3, soaking the plastic bottle pieces processed in the step B2 in a three-stage cleaning pool, and adding clear water into the cleaning pool.
The cleaning agent comprises the following raw materials in parts by weight: 10-20 parts of tetradecyl dimethyl sulfopropyl betaine, 400 parts of water 200-sodium silicate, 12-18 parts of polyacrylamide, 6-10 parts of anhydrous sodium metasilicate, 8-12 parts of activated carbon, 3-6 parts of copper hydroxide and 50-60 parts of anhydrous ethanol.
The preparation method of the cleaning agent comprises the following steps: grinding the activated carbon, anhydrous sodium metasilicate and copper hydroxide at a constant temperature, adding absolute ethyl alcohol in the grinding process, and grinding for 10-20 minutes to obtain a material I; dissolving tetradecyl dimethyl sulfopropyl betaine in water, heating to 40 deg.C in water bath, and keeping the temperature for 40min to obtain material II; and mixing the material I and the material II, adding polyacrylamide, stirring and mixing at the stirring speed of 800-1000r/min for 10-20 minutes to obtain the cleaning agent.
