Description
Technical Field
[0001] This utility model belongs to the field of waste pretreatment technology, and in particular relates to a 30MPa dry-wet separation device. Background Technology
[0002] In recent years, with the increasing awareness of environmental protection and continuous technological progress, dry-wet separation equipment, as an important type of environmental protection equipment, has been widely used in large-scale wastewater treatment and municipal solid waste treatment, leading to increasingly higher requirements for such equipment. Dry-wet separation rate, production efficiency, energy consumption, and equipment stability are important indicators for dry-wet separation equipment, with the dry-wet separation rate being the key indicator, used to measure the performance of the equipment and its impact on subsequent processes. Due to the complexity of the physical and chemical properties of municipal solid waste, and the slow progress of waste sorting in some cities, a large amount of mixed municipal solid waste still requires pretreatment. This mixed waste often contains materials with special properties, such as high viscosity, high concentration, and high moisture content. Currently, dry-wet separation equipment on the market for mixed municipal solid waste with high viscosity, high concentration, and high moisture content often struggles to achieve ideal separation and productivity rates. Traditional waste compactors, integrated containers, and waste compression trucks typically operate at a compression chamber pressure of 0.1–1 MPa. While some improved dry-wet separation equipment increases the compression chamber pressure to around 3–8 MPa, this often comes at the cost of productivity. More importantly, a low separation rate negatively impacts subsequent processing. Poor separation results in high moisture content and low calorific value in the dry residue. If this residue is sent to an incineration power plant, it reduces incineration efficiency; if it's landfilled, the high moisture content generates large amounts of leachate, increasing landfill maintenance costs. Therefore, the market needs equipment or facilities that can solve these problems. Summary of the Invention
[0003] The purpose of this invention is to expand waste pretreatment technology and provide a 30MPa dry-wet separation device that separates mixed municipal solid waste into dry and wet materials, thereby increasing the calorific value of municipal solid waste and collecting wet waste for subsequent treatment processes. This achieves the goal of improving power generation efficiency and reducing the adverse effects of leachate on terminal treatment sites.
