Charcoal production from house refuse

Abstract

Carbon production by domestic refuse is carried out by: 1.transporting the domestic refuse to pre- treating pool, conveying it by conveyer belt and first sizing, and reutilizing the sized metal materials, glass and building refuse; 2 roughly breaking the sized domestic refuse with 3-5cm grain, magnetic separating and removing fine iron; 3.drying, shining and extruding the magnetic separated refuse to make, the water content <3-20%, and fine breaking with 1-2cm grain; 4. press shaping the fine refuse; 5. transporting the compressed refuse to carbonized apparatus, high-temperature treating at 300-1200deg.C for 0.5-1.5hrs to obtain semi-coke.

Description

technical field

[0001] The technical method for making charcoal from domestic waste of the invention relates to a technical method for making charcoal by using urban and rural domestic waste. Background technique

[0002] With the rapid development of economic construction and the continuous improvement of urban and rural living standards, the living structure and consumption level are gradually improved, the consumption of various materials is increasing, the composition of domestic waste is changing, and the output is also increasing year by year.
