The invention discloses a method and a continuous
system for treating wet organic waste, and belongs to the field of
environmental protection /
sewage treatment /
sludge treatment. The method includes steps of conveying and preheating raw materials; carrying out hydrothermal oxidation reaction; removing
oxygen from oxidation reaction products; recycling reaction heat; carrying out flash
dehydration; carrying out mechanical
dehydration; treating filter liquid; treating
tail gas. The continuous
system comprises a wet organic waste
raw material pump, a sleeve heater, a hydrothermal oxidation reactor, an
oxygen remover,
waste heat recycling heat exchangers, a byproduct steam
plant, a flash
plant, a
dehydration plant and a
tail gas treatment plant. The method and the continuous
system have the advantages that the continuous system is simple, the wet organic waste can be directly treated without being dried, the reaction is easy to maintain under self-heating conditions without external heat, a large quantity of heat of the high-temperature materials can be recycled, the method and the continuous system are high in energy
utilization rate, and a large quantity of economic byproducts (steam) can be generated; problems that existing
raw material preheating heat exchangers are vulnerable to blocking and existing
waste heat recycling heat exchangers are vulnerable to
corrosion can be solved by the aid of the method and the continuous system.
