The invention relates to a hazardous waste incineration system assembly, in particular to an energy-saving denitration device for a hazardous waste incineration system. The energy-saving denitration device for the hazardous waste incineration system comprises a vapor heat exchanger, a denitration tower, a draught fan and a chimney. The device is characterized by further comprising a first heat exchanger and a second heat exchanger. A low-temperature medium outlet of the first heat exchanger is connected with a low-temperature medium inlet of the second heat exchanger. A low-temperature mediumoutlet of the second heat exchanger is connected with a low-temperature medium inlet of the vapor heat exchanger. A low-temperature medium outlet of the vapor heat exchanger is connected with a gas inlet of the denitration tower. A gas outlet of the denitration tower is connected with a high-temperature medium outlet of the second heat exchanger. A high-temperature medium outlet of the second heatexchanger is connected wi
