Resourceful treatment of paper mill strand rope is a comprehensive process aimed at converting solid wastes such as strand rope produced in the papermaking process into valuable resources in order to reduce environmental pollution and realize effective recycling of resources. The following is a detailed description of the paper mill strand rope resource treatment:
01.Pre-preparation and estimation
Stranded rope is a paper mill in the paper making process, hydraulic pulper in the stranded rope will be waste paper pulp in a variety of light impurities, such as wire, plastic, fine rope, cotton yarn, etc. constantly winding stranded set and become a stranded rope, that is, stranded rope. It is also called twisted rope pulp residue, pulping tail rope, which contains 40% of iron wire and 55% of paper mill waste, as well as pulp residue and light residue, belonging to a kind of material difficult to be broken.
02.Processing flow
Shredding
Paper mill stranded rope is fed into double shaft shear shredder through conveyor for initial pre-shredding, paper mill stranded rope shredder adopts high strength spindle, high wear-resistant knives and is equipped with anti-twisting fixed knives, which can effectively avoid the material tangled shaft or jammed, and improve the production efficiency.
The shredded material will be further reduced in size through the fine shredder to ensure that it meets the subsequent processing requirements.
Separation
Magnetic separation: the use of magnetic separator to effectively separate out iron wire and other metal substances, to achieve direct recovery of metal.
Intelligent sorting: Through the intelligent sorting system, different materials such as plastics and pulp are further separated to prepare for subsequent resource utilization. The wind separator (light material separator) is also one of the key equipments, utilizing the principle of aerodynamics and the difference in material density to precisely separate the shredded materials.
Removing impurities
De-dusting of non-metallic parts such as plastics, pulp, etc., such as dust removal and iron removal.
Preparation process: The shredded and sorted materials of paper mill stranded rope light residue are prepared into Solid Recovered Fuel (SRF) or Refuse Derived Fuel (RDF) through drying and decontamination processes.
03. Highly efficient automation and intelligence
Intelligent control: The whole treatment process adopts high efficient automation design, such as anti-clogging design to ensure continuous and stable operation of the equipment, and intelligent control system to realize automation and remote monitoring of the treatment process.
Customized service: According to the specific needs of paper mills, we provide personalized design solutions, including equipment selection, layout planning, installation and commissioning.
04. Environmental protection and economic benefits
- Environmental compliance: the entire treatment process needs to comply with environmental standards to ensure that waste gas and waste water emissions comply with regulations.
- Economic benefits: through resource disposal, the paper mill strand rope and other solid wastes are not only effectively treated, but also transformed into resources with economic value, realizing a win-win situation for both environmental and economic benefits.
05. Thermal energy utilization
Paper mill strand is prepared into solid recycled fuel (SRF) or refuse-derived fuel (RDF), which can be used for cogeneration or directly replace coal, providing clean energy for power plants and reducing fuel costs.
The Paper Mill Strand Rope Resource Treatment Solution is a comprehensive systematic project involving multiple aspects such as pre-preparation, shredding and processing, sorting system, preparation process, heat utilization, environmental protection and safety as well as customized services. It is a comprehensive process integrating environmental protection, economy and high efficiency, which is of great significance for promoting the sustainable development of the paper industry. The resourceful treatment solution for paper mills can realize the resourceful utilization of stranded rope and other solid wastes and promote the sustainable development of the paper industry.
