Technical Field
According to the on-line article from the Chinese environmental newspaper, which is the resource way of the waste textiles? Introduction:
……
according to data provided by the union of the textile industry of China, 4970 ten thousand tons of textile raw materials are consumed in 2016 years of the textile industry of China, the consumed total amount accounts for 48 percent of the global consumption total amount of the textile raw materials, 52 percent in 2017 and about 55 percent in 2018, and the method is the top of the world.
……
The published data show that in 2018, the comprehensive utilization amount of waste spinning in China is about 380 ten thousand tons, and the comprehensive utilization rate reaches about 19%. Although the waste spinning utilization rate is improved, the method still has a large development space.
Professor Zhao Guo of the Beijing clothing academy of China Apparel science and technology research institute is called: if the waste textiles can not be fully utilized, on one hand, the waste of raw materials such as natural fibers such as cotton, wool, silk and hemp and synthetic fibers taking petroleum as raw materials and the waste of energy in spinning, dyeing, finishing and other links can be caused; on the other hand, chemical fibers are difficult to degrade in nature, and if the chemical fibers are treated by methods such as landfill, the long-term pollution to the environment can be caused. Therefore, the utilization problem of the waste textiles is not only a resource recycling problem, but also a great environmental problem. "
According to the research data of the research institution of the Copenhagen university, the carbon dioxide emission is reduced by 3.6 kg when one kg of waste textile is used.
……
From the perspective of energy saving and carbon reduction, the method has important significance for improving the recycling and harmlessness of waste spinning and promoting the efficient utilization of the waste spinning. However, efficient use of waste spinning is still a problem due to technical and cost limitations.
……
The application of the plastic high polymer materials is already enriched in the aspects of social life, and the harmless treatment of waste plastic recycling enterprises is green industrial upgrading and becomes an indispensable important content in the development of green recycling economy.
There is also a consensus in the waste plastic recycling industry, both: waste plastics with the same or similar melting temperature are resources; waste plastics with different melting temperatures or other foreign matters such as metal and paper are garbage, and the mixed materials have the problem of difficult granulation in a hot extrusion granulator. For this reason, many enterprises of waste paper recycling paper making, plastic packaging, labeling, shoe making and the like are disposed of in the production process, such as: the waste plastic film dregs discarded by waste paper regeneration, the plastic film waste packaging bags of commodities, the cutting/punching edge materials in the production of the plastic film packaging bags, the waste composite plastic film materials, the plastic film composite release paper/film discarded in the production/use of trademark labels, the waste aluminum-plastic composite films and the like, the waste edge materials of plastic shoes, the waste polyurethane soles and the like all become wastes without any requirement for much fluid, and the existing disposal routes of the mixed materials or/and the composite materials are mainly incineration and landfill.
On the other hand, in China, a large number of waste plastic recycling enterprises are engaged, and the enterprises are reported to have serious pollution in the process of disposing waste plastics in media. The pollution of the enterprises reported by the detailed media is at least four: firstly, the visual pollution caused by stacking and scattering of the waste plastic and pickled goods raw materials; secondly, the discharge of cleaning water of waste plastic raw materials is polluted; thirdly, the noise pollution to the processing machinery of the waste plastic raw material; fourthly, the waste plastics are polluted by the foul smell of smoke dust/moisture in the hot extrusion granulation process.
In the industry, equipment innovation aiming at the problems of difficult feeding, impurity removal and the like of materials with low bulk density and limited by waste plastics containing impurities is worth mentioning as follows: CN201420253746.9, the utility model discloses a feeding device of a plastic extruder, which can realize continuous and stable feeding of film waste plastics, is provided with a large-compression anti-blocking and returning device, can effectively improve the working efficiency of the extruder, expand the application range and greatly reduce the maintenance cost of equipment; the following steps are repeated: CN201921398872.2, this utility model discloses an automatic row's sediment device of plastics recycling machine filter can realize the filter to impurity exhaust's accurate control, and can not produce harmful flue gas, has simple structure practicality, easy and simple to handle, produces green's characteristics. However, these improvements cannot solve the visual pollution caused by the stacking and scattering of the waste plastic and blister raw materials in various enterprises engaged in waste plastic recycling in China, and also cannot solve the outward discharge pollution of cleaning water of the waste plastic raw materials in various enterprises, and further do not relate to how to reduce the temperature of a hot extruder during granulation.
The process innovation aiming at the problems of regeneration high temperature odor, impurity removal and the like of waste plastics containing impurities in the industry is worth mentioning as follows: CN202010141136.X, the technical scheme of the invention mainly comprises four: one is to provide a new process for grinding and regenerating miscellaneous waste plastics, and to provide a defined range for miscellaneous waste plastics suitable for the new process, wherein the defined range includes various varieties which are difficult to granulate and regenerate in the current hot extrusion process, such as water sediment in miscellaneous waste plastic film materials discarded by the regeneration paper industry; secondly, a two-component preparation of a regenerated plastic product is provided to solve the technical scheme that the production method is simple and efficient and the objective user has various and complicated requirements; thirdly, new equipment required by grinding regeneration is provided, and grinding unit machinery and combined equipment used for carrying out grinding regeneration on the waste plastics are improved, so that the finally obtained regenerated product can be more towards the uniformity of material/color and the like; fourthly, the heating temperature of the materials during grinding and granulating is reduced by more than half compared with the traditional hot extrusion method. However, the improvement can not solve the problem of large visual pollution caused by stacking and scattering of waste plastic and goods-soaking raw materials in various enterprises engaged in waste plastic recycling in China.
In view of the above, there is still a need in the industry to provide a solution for the disposal of a large amount of mixed waste plastics/waste fibers, including floc, cloth, film, leather, foam, etc. having a bulk specific gravity far less than 1, which are mixed or/and compounded at present, in upstream enterprises, particularly in various related enterprises gathered from parks, and which can be collected in large quantities by the owners of the various mixed waste fibers and waste plastics, and which are subjected to large-scale gardened areas, and harmless rapid decrement, and which are favorable for the subsequent upgrading; the proposed solution not only should meet the general requirements of green cycle of resources for the industry chain; the method is further expected to solve the problems of visual pollution of waste fiber and waste plastic foam materials in the prior art when a plurality of enterprises engaged in waste fiber/waste plastic composite regeneration granulation or plastic products are downstream.
