The utility model discloses a
fly ash in-situ
treatment system of a waste
incineration power
plant. The
fly ash in-situ
treatment system comprises a low-temperature
pyrolysis unit, a washing MVR (mechanical vapor recompression) salt separation unit and an artificial aggregate unit, the low-temperature
pyrolysis unit comprises a low-temperature
pyrolysis reactor, a cooling section and a gas-gas
heat exchanger, the low-temperature pyrolysis reactor is connected with the cooling section, the cooling section is connected with the washing MVR salt separation unit, and the low-temperature pyrolysis unit completes pyrolysis treatment of input waste
incineration fly ash; the washing MVR salt separation unit comprises a washing module, a filter pressing module, a dosing
sedimentation tank, an MVR
evaporator, a
crystal slurry tank, a thickener and a centrifugal
machine which are connected in sequence, and a
salt solution from the filter pressing module passes through the dosing
sedimentation tank, the MVR
evaporator, the
crystal slurry tank, the thickener and the centrifugal
machine to obtain
calcium chloride,
sodium chloride and
potassium chloride products; the artificial aggregate unit comprises a dryer, a fly ash bin, a mixing granulator and screening equipment which are connected in sequence, and is used for completing
granulation treatment on input materials.
