Embodiment Construction

[0027] A method for producing refuse-derived fuel and diesel from municipal refuse, comprising the following steps:

[0028] (1) Bag breaking process: bagged garbage is broken and rolled;

[0029] (2) Primary crushing process: Primary crushing of the garbage mixture into smaller pieces with a diameter of 2-4 cm by crushing equipment;

[0030] (3) Magnetic separation process: separate and remove scrap metal substances from the above mixture fragments;

[0031] (4) Manual screening and winnowing process: The primary crushed materials obtained in the above steps are first manually screened to select kitchen waste and harmful waste substances, and then carried out winnowing to screen out inorganic waste solids and combustibles; the screened Combustibles are transferred to the following processes;

[0032] (5) Secondary crushing: Secondary crushing of the combustible waste obtained above into fine pieces with a diameter of 3-8mm;

[0033] (6) Sterilization and drying: Sterilize ...

Abstract

The invention discloses a method for preparing garbage derived fuel and diesel fuel from city garbage. The method comprises the following steps: a working procedure of breaking bags, a working procedure of elementary crushing, a working procedure of magnetic separation, a working procedure of pneumatic separation, secondary crushing, sterilizing and drying, mixing, forming, a catalysis decompressing depolymerization reaction, rectification and the like. Through the adoption of the method disclosed by the invention, the problems that valuable garbage is wasted, land resources are occupied and harmful gas is emitted due to garbage disposal at present are solved. The requirements for the temperature and the pressure of the reaction of a catalysis low-pressure depolymerization technology preparing the diesel fuel through screened combustible garbage are not high, but the synthesis efficiency is extremely ideal, so that firm foundation is laid for the industrialization of large-scale devices in the future.

Description

technical field [0001] The invention relates to a method for producing garbage-derived fuel and diesel from municipal garbage. Background technique [0002] With the rapid development of my country's economy, the problem of garbage treatment and disposal has become a problem that must be solved in the development of large and medium-sized cities in my country. By 2010, the total output of municipal solid waste in the country had reached 152 million tons, and it is estimated to reach 179 million tons in 2015. The goal of solving my country's urban domestic waste is to realize waste reduction, resource utilization and harmless treatment. At present, the garbage disposal methods adopted in my country mainly include: sanitary landfill, composting and incineration for power generation. [0003] Compared with traditional garbage landfills, turning municipal garbage into garbage-derived fuel and diesel can save landfill resources and turn waste into treasure. It is the best way t...
