The invention discloses a fluidized-bed high-temperature incineration and purification all-in-one device and method for resin type dangerous waste. The device comprises a feeding unit, an incinerator, a smoke purifying unit, a heat energy utilizing unit and a smoke emission unit. The resin type dangerous waste is conveyed to the incinerator through the feeding unit and is combusted to generate high-temperature smoke, the smoke purifying unit is used for efficiently removing dioxin, nitric oxides (NOx), acid gas, heavy metal, dust and other pollutants in the smoke, the heat energy utilizing unit is used for efficiently utilizing heat in the smoke, and the smoke emission unit is used for emitting clean smoke to the air. According to the device, a high-temperature two-combustion-chamber unit adopting diesel as fuel of a traditional dangerous waste incineration device is omitted, pi-shaped integrated arrangement is formed as a whole, the technological process is simplified, and occupied space is reduced; moreover, efficient heat utilization is achieved, and investment cost and operation cost for incineration treatment of the resin type dangerous waste are lowered.
