Consumer waste multipurpose reutilization system

Abstract

The invention relates to a multifunctional recycling system for living garbage which comprises a cracking device, a firedamp device, a screening equipment and a burning device; the discharge opening of the cracking device is connected with the feeding opening of the firedamp device through a transmission device; the sediment discharge opening of the firedamp device is connected with the feeding opening of the screening equipment through the transmission device; the discharge opening of the matters on the screen of the screening device is connected with the feeding opening of the burning device through the transmission device; the generated materials of big block can be directly recycled; the magnetic materials which are mainly of iron can be directly used as metallurgical materials; the generated firedamp can be used as fuel gas; the generated mud can be used as the materials for preparing fertilizers, soil modifying agents and building materials ; the generated heavy materials can be used as the building materials or as filling materials. The system effectively utilizes various materials and energies in living garbage and is beneficial to save the treatment cost, reduce the environment pollution and is able to obtain useful materials and energies.

Description

technical field [0001] The invention relates to a garbage treatment technology, in particular to a multipurpose recycling system for domestic garbage, which belongs to the technical field of environmental protection. Background technique [0002] Household waste includes multiple components, such as food waste, plastic, metal, glass, ceramics, dust, etc. At present, these wastes are basically disposed of by landfill and incineration, and these disposal methods have insurmountable defects , For example, for landfill treatment, it needs to occupy a large amount of landfill sites, and there is a risk of pollution such as seepage. At present, it is difficult to find suitable landfill sites for many large and medium-sized cities; for incineration treatment, the construction of incineration facilities and operating costs are relatively high, energy consumption is required, and there is smoke pollution. Although people are constantly developing new incineration technologies and flu...

[0002] Household waste includes multiple components, such as food waste, plastic, metal, glass, ceramics, dust, etc. At present, these wastes are basically disposed of by landfill and incineration, and these disposal methods have insurmountable defects , For example, for landfill treatment, it needs to occupy a large amount of landfill sites, and there is a risk of pollution such as seepage. At present, it is difficult to find suitable landfill sites for many large and medium-sized cities; for incineration treatment, the construction of incineration facilities and operating costs are relatively high, energy consumption is required, and there is smoke pollution. Although people are constantly developing new incineration technologies and flue gas treatment technologies, the inherent nature of converting one pollution method to another Defects are still impossible to fundamentally overcome
