Garbage sorting technology, as a front-end technology for garbage treatment, is an essential program for the reuse of resources and the subsequent processing chain of garbage treatment. And especially in the chain of garbage incineration, sorting technology is particularly important. Garbage sorting can not only improve the utilization rate of resources and achieve their reuse, but also enhance the efficiency of garbage incineration.

Wind sorting

The basic principle of wind sorting is that the airflow carries lighter materials upwards or horizontally towards farther places, while heavy materials settle due to the inability of the rising airflow to support them, or are thrown out at a closer distance in the horizontal direction due to inertia. The wind sorting process is based on the settling law of various solid particles in the air. Fengxuan mainly recycles recyclable materials such as paper and plastic.

magnetic separation

Magnetic separation technology is mainly applied to the classification of mineral resources. The working principle of magnetic separation is that after other materials are fed into the separation space of the magnetic separator, they are subjected to the combined action of magnetic force and other mechanical forces (such as gravity, centrifugal force, friction force, medium resistance, etc.).

Bounce sorting

Bouncing sorting machine is a conveying equipment with separation function designed for sorting inorganic particles in garbage after rough crushing. This machine utilizes the characteristics of crushed garbage materials, and the conveyor belt is designed with a bouncing function to separate inorganic particles or other hard particles while conveying the material on one side. The separated particles move in the opposite direction to the conveyed material to achieve the purpose of sorting. Bounce sorting mainly involves selecting components such as batteries, ceramics, and bricks.

density separation

Mainly sorting based on the density of objects, classifying garbage with different density values.

Automatic Sorting

The automatic sorting technology of domestic waste is a relatively mature waste sorting technology in China at present. This technology combines mechanical, automatic control, microbiological and other means, and adopts the original mechanical biological sorting method and device in the fluid environment, the comprehensive wetland treatment and recycling technology of sewage, TR microbiological disinfection and other technologies. The whole system has a high degree of automation, few people directly participate in it. There are 22 classified outlets in the whole system, which can classify (or separate) mixed domestic waste into 11 kinds of materials, such as super large waste, ferrous metals, non-ferrous metals, plastics and foam materials, flexible strips, perishable organics, incorruptible organics, masonry glass, silt, waste batteries, landfills, and so on. The waste recycling rate of waste reaches more than 85%. Moreover, the sewage, dust, bacteria and viruses in the treatment project have been treated and controlled.

In order to further improve the level of urban solid waste sorting technology in China, it is necessary to optimize and innovate the automatic sorting technology for urban solid waste resource utilization, improve its sorting efficiency and accuracy, reduce system construction costs and operational energy consumption, material consumption, and management investment. If the optimized and innovative urban household waste resource sorting technology is adopted, more than 90% of the components in the waste can be utilized as resources, greatly reducing the amount of waste landfilled and extending the service life of urban household waste landfills. Garbage sorting technology provides greater possibilities for achieving the goal of harmless and reduced waste in garbage treatment.
