[0061] Using a city's domestic waste as raw material, the water content of the waste is 54%, and its composition is shown in Table 1:
[0062] Table 1 Composition of domestic waste (wt%)
[0063]
[0064] The waste entering the factory is firstly pretreated, and the pretreatment includes:
[0065] (1) Sorting of domestic waste: mainly adopt drum sieve, air separation, magnetic separation and other methods to separate large pieces of inorganic matter, glass, metal and other substances in the waste;
[0066] (2) Household waste crushing: the sorted waste is crushed into small pieces with a particle size of 30mm-40mm through a two-stage crushing device;
[0067] (3) Drying of domestic garbage: The drying temperature is 180°C, the heat source is flue gas after radiant tube combustion, and the moisture content of the dried garbage is 13%.
[0068] (4) Forming of domestic waste: the dried domestic waste is compressed and formed into rods by waste forming equipment. The diameter...
