RDF Solid Alternative Fuel Intelligent Treatment System for Paper Mill Waste (Rope, Heavy, Light)

(Paper waste crusher, paper waste treatment, paper waste damage treatment)

In the process of pulp and paper production, various types of solid waste (i.e. waste residue) are generated. For example, a paper mill with an annual production capacity of 1 million tons accounts for about 10% of its waste residue, which is 100000 tons per year. Its quantity is huge and highly concentrated. If not properly disposed of, it can also cause significant pollution and endanger the ecological environment.

The composition of papermaking waste is very complex, mainly including ropes, cotton yarn, cotton cloth, paper residue, wood chips, rubber, plastic, electronic parts, wire, nails, aluminum cans, PE plastic bottles, wax paper glass, stones, and sand. Paper waste can be used to produce solid alternative fuels, which not only reduces waste but also replaces traditional fossil fuels and reduces carbon emissions.

The plastics in papermaking waste cannot be degraded, and direct stacking seriously affects the ecological environment. At present, there are difficulties in sorting and removing impurities from papermaking waste, low degree of resource utilization, and extensive terminal treatment, which result in resource waste and pose certain environmental risks and safety hazards. With the tightening of environmental policies, the development demand for clean production in the paper industry, and the upgrading of solid waste disposal technology, the energy utilization of paper waste residue is the trend. Combustible components account for over 80% of papermaking waste, with a moisture content of 50% -60%. Through pre-treatment systems such as grabbing or chain plate feeding, multi-stage crushing, magnetic separation and recovery, density screening, eddy current separation, and transportation, metal materials are effectively separated from inert and non combustible materials, obtaining uniformly sized combustible materials. This is very beneficial for stable combustion of boilers and can reduce secondary pollution.

The manufacturing process of the RDF solid alternative fuel intelligent treatment system for papermaking waste residue (twisted rope, heavy residue, light residue) is dehydration molding, and the sorting process separates metals, heavy materials, etc., greatly reducing the impact on boiler combustion in the later stage. The manufacturing process does not produce harmful waste gas. The moisture content of fuel rods is less than 20%, and after storage for a period of time, it can be less than 15%. It has good anti-corrosion properties and will not absorb moisture and crush, making it easy to transport. The calorific value is about 5000 kcal, and the shape is consistent and uniform, which is very conducive to stable combustion and improving efficiency. It is very beneficial for stable combustion of boilers and can also reduce the generation of secondary pollution. The entire production system occupies a small area and can be installed next to the paper pulp line, solving the problems of secondary transportation of waste residue and water washing wastewater treatment, providing strong support for clean production, pollution reduction, carbon reduction, and synergistic efficiency enhancement in paper enterprises.
