High-efficiency incineration power generation system for municipal solid waste

Abstract

A high-efficiency incineration power generation system for municipal solid waste, comprising the following steps: (1) rough separation; (2) breaking the plastic bag to disperse the internal materials; (3) magnetic separation, separating ferrous metals ; (4) Screening; the material under the screen (sand) is harmlessly landfilled, and the material on the screen is directly crushed; (5) degradation, the material in the screen is degraded, (6) extrusion dehydration; (7) drying (8) crushing; (9) molding; (10) incineration; (11) power generation; slag can be made into burn-free bricks. The invention not only solves the problem that municipal solid waste is difficult to handle, but also turns it into a renewable fuel block with high calorific value, which becomes a new energy source, has small investment and occupied area, short processing cycle and low operating cost.

Description

Technical field: [0001] The invention relates to a treatment process of municipal domestic garbage, in particular to the field of high-efficiency incineration of municipal domestic garbage to generate electricity. Background technique: [0002] The composition of China's urban domestic waste is complex, including waste paper, clothing, muck, metal, glass, kitchen waste, etc., which are difficult to effectively deal with. At present, there are certain limitations in the composting process, direct incineration process, and landfill process in waste treatment technologies. Defects. For example, landfill treatment not only occupies a large area, but also causes secondary pollution such as polluted water and air. At present, it is difficult to find suitable landfill sites in many large cities. The composting process has a long treatment cycle and produces high-concentration wastewater, which is difficult to treat and pollutes the environment. The direct incineration process has...

Problems solved by technology

[0002] China's urban domestic waste has complex components, including waste paper, clothing, muck, metal, glass, kitchen waste, etc., and it is difficult to effectively deal with it. At present, there are certain limitations in the composting process, direct incineration process, and landfill process in waste treatment technologies. Defects

For example, landfill treatment not only occupies a large area, but also has secondary pollution such as polluted water and air. At present, it is difficult to find suitable landfill sites in many large cities.

The composting process has a long treatment cycle and produces high-concentration wastewater, which is difficult to treat and pollutes the environment

The direct incineration process has high construction and operating costs, consumes energy, and has flue gas pollution
