Problems solved by technology

[0002] With the increase of urban population, there are more and more urban domestic garbage, and the disposal of domestic garbage has become a major problem; at present, garbage is used for landfill, plant fertilizer preparation or incineration for power generation, and these garbage disposal methods are all It is relatively simple, and it is easy to cause secondary pollution and waste of resources
[0003] Household garbage mainly includes: plastic bags, fruit peels, paper scraps, wood chips, packaging, leftovers, old clothes, bricks, sand, broken glass and other substances, and these garbage contain a lot of organic matter. It is easy to pollute the environment in the process of preparing plant fertilizer and organic fertilizer

Abstract

The invention relates to a method for manufacturing an organic brick by utilizing domestic garbage. The method comprises the following steps of: taking domestic garbage with the diameter being not larger than 150mm, drying, crushing the domestic garbage to be material with the diameter being not larger than 25mm, sorting the material with the diameter being not larger than 25mm to obtain organic matters, mixing 2-4% of additives and 96-98% of organic matters in weight percentage to form a mixture, sterilizing for 20-60min at 100-270 DEG C, feeding the sterilized mixture into a brick manufacturing machine, manufacturing a blank brick under 9.807-19.613MPa, and finally carrying out a constant-temperature carbonizing reaction on the blank brick for 6-24h at 300-1100 DEG C to obtain products. The method for manufacturing the organic brick by utilizing the domestic garbage, disclosed by the invention, has the advantages of simple process, simpleness in operation, environment pollution reduction, energy source consumption reduction, production cost saving and labor consumption reduction.

Description

Technical field [0001] The invention relates to a method for preparing organic bricks, in particular to a method for preparing organic bricks from domestic waste. Background technique [0002] With the increase of the urban population, more and more municipal solid waste, the disposal of solid waste has become a major problem; at present, all waste is used for landfill, plant fertilizer preparation or incineration for power generation, and these waste treatment methods are all It is relatively simple, and it is easy to cause secondary pollution and waste of resources. [0003] Domestic garbage mainly includes: plastic bags, peels, paper scraps, sawdust, packaging, leftovers, worn-out clothes, bricks, sand, broken glass and other materials. These garbage contains a lot of organic matter. At present, the organic matter in the garbage is often removed. It is easy to pollute the environment in the process of preparing plant fertilizer and organic fertilizer. Summary of the invention ...
