Example Embodiment

[0032] Example 1

[0033] Such as figure 1 As shown, a system for deep resource utilization of municipal solid waste in this embodiment includes a waste sorting system and a resource utilization system;

[0034] Wherein, the garbage sorting system includes a garbage shredding system and a magnetic separation system connected in sequence, and the magnetic separation system is respectively connected with a metal recycling system, an inorganic recycling system, and an organic recycling system. The mentioned resource utilization system connection;

[0035] The resource utilization system includes a cracking system and an oil purification system, the cracking system includes an organic compound pretreatment structure, the organic compound pretreatment structure is connected to a cracking furnace, and the cracking furnaces are respectively connected with exhaust gas A processing device, a gas-solid separation tower and a gas storage tank. The gas-solid separation tower is sequentially co...

Example Embodiment

[0048] Example 2

[0049] The method for in-depth resource utilization of municipal solid waste in this embodiment includes the following steps:

[0050] (1) Put the municipal solid waste into the garbage sorting system first. After the waste crushing system and the magnetic separation system, the municipal solid waste is divided into inorganic matter, metal and organic matter, and enter the inorganic matter recycling system, metal recycling system and organic matter respectively. Recycling system for recycling processing;

Abstract

The invention discloses an urban domestic waste deep resource utilization system and method. The system comprises a waste classification system and a resource utilization system, wherein the waste classification system comprises a waste crushing system and a magnetic separation system in sequential connection; the magnetic separation system is respectively connected with a metal recovery system, an inorganic matter recovery system and an organic matter recovery system; the organic matter recovery system is connected with the resource utilization system. By using the system provided by the invention, the urban domestic waste is classified; various kinds of substances are sequentially classified and are sufficiently recovered and reused; the organic matters are subjected to cracking and purification treatment to obtain clean diesel oil, so that the pollution of the waste on atmosphere, water body and soil is reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental management and restoration, and in particular relates to a system and a method for deep resource utilization of municipal solid waste. Background technique [0002] Energy and environmental issues are always issues of global concern and need to be solved urgently. With the rapid development of human population towards urbanization and the rapid development of industrial modernization, non-renewable natural resources such as oil, coal, and natural gas have been consumed in large quantities. The problem is becoming more and more prominent, and land resources are becoming more and more scarce. The management and resource utilization of urban domestic waste is a worldwide problem. At present, there is no optimal disposal method that is both environmentally friendly and resource-efficient without occupying arable land. [0003] Municipal solid waste is the complete and ultimate waste of various ...
