The invention provides a method and a
system for
drying aerobic organisms in urban raw garbage by the aid of hot air. Organic matters in the urban raw garbage are decomposed into
moisture and other inorganic matters by the aerobic microorganisms in the urban raw garbage with high-temperature biological conditioners by the aid of
oxygen provided by the hot air and a formed high-temperature environment, heat is released, most of the
moisture is heated and evaporated into steam by the high-temperature environment and the heat, the steam is exhausted in a wet and hot
waste gas form, garbage
leachate is formed by an additional part of the
moisture and drained, and the purpose of
drying the aerobic organisms in the urban raw garbage is achieved. The
system comprises an urban raw garbage
aerobic organism drying bin, a hot-air auxiliary drying device, an air feeder, an exhaust fan, a liquid delivery pump and the like. The method and the
system further can be optimized by means of
automatic control,
waste gas preheating, photocatalytic sterilization and deodorization and the like. The method and the system for drying the aerobic organisms by the aid of the hot air have the advantages that the
decomposition degree of the organic matters in the urban raw garbage and moisture
evaporation capacity are high, a drying process is short, a drying effect is obvious, and the garbage is treated in a harmless, reducing and stable manner.
