The invention relates to a rotation destructive distillation thermal cracking device of a solid energy substance. The rotation destructive distillation thermal cracking device is characterized in that system main equipment of the device is an inclined destructive distillation machine, an inclined angle of the destructive distillation machine is 1 to 5 degrees, and a rotary driving device is arranged; the front part of the destructive distillation machine is connected with a middle temperature air exhaust box, a destructive distillation raw material hopper, a feeding device of the destructive distillation machine, a destructive distillation raw material transfer box, a destructive distillation raw material reserve bin, a lifter and a belt conveyor in sequence; the rear part of the destructive distillation machine is connected with a high temperature air supply box, a gas-carbon separator, a carbon machine, a tar cracker, a high temperature heat exchanger, a lower temperature heat exchanger, a spray tower, a gas-water separator, an induced draft fan and a water sealing machine in sequence. A destructive distillation machine cylinder is horizontally inclined, the continuous operation of destructive distillation of the solid thermal energy substance is guaranteed, materials can be heated uniformly, is overturned and displaced spirally from high to low, and a thermal chemical reaction is sufficient. The materials of the device are extensive in adaptability, the gas production is large, the heat value is high, and environmental pollution is reduced.
