The invention relates to the technical field of the
resource utilization of
livestock and poultry breeding waste, and discloses a continuous
hydrothermal carbonization system for
livestock and poultryexcrement. The continuous
hydrothermal carbonization system comprises a
fermentation tank, a high-pressure
sludge pump, a heater, a
carbonization reactor, a cooler, a
storage tank, a
sludge pump anda
solid-liquid separator, wherein the
fermentation tank, the high-pressure
sludge pump, the heater, the
carbonization reactor, the cooler, the
storage tank, the sludge pump and the
solid-liquid separator are communicated in sequence; the
fermentation tank is also communicated with a first gas collection device through a pipeline; the
storage tank is also communicated with a second gas collection device through a pipeline. The invention also discloses a continuous
hydrothermal carbonization process for the
livestock and poultry excrement. The continuous hydrothermal
carbonization process comprises the following steps of fermenting the pretreated livestock and poultry excrement in the anaerobic fermentation tank, then continuously inputting into the heater, the carbonization reactor and cooler through power provided by the high-pressure sludge pump, and separating a temperature-lowered carbonization product through the
solid-liquid separator to obtain hydrothermal carbon and carbonized liquid. The
system is used for treating the livestock and poultry excrement by adopting a continuous hydrothermal carbonization method to prepare the hydrothermal carbon, meanwhile, is used for obtaining the by-product carbonized liquid, and have the advantages of being convenient to operate, easy to maintain, low in production cost, zero-release in
pollutant and low in
energy consumption, and thelike.
