The invention provides a heat storage type heating separating device, and relates to the technical field of dry distillation equipment. The heat storage type heating separating device comprises a dry distillation device, a first heating device, a first heat storage device and a first driving device. Feed inlets, a discharge outlet and a gas outlet are formed in the dry distillation device; the first heating device is positioned on a side of the dry distillation device; the first heat storage device is of a closed ring structure, one end of the first heat storage device is positioned in the first heating device, the other end of the first heat storage device is positioned in the dry distillation device, the first driving device is used for driving the first heat storage device to carry out circulating rotation, and a combined sealing device is arranged between the first heating device and the first heat storage device; the feed inlets are formed in the left end of the top of the dry distillation device and are particularly formed in positions above the first heat storage device; the discharge outlet is formed in the end, which is far away from the feed inlets, of the bottom of the dry distillation device and is particularly formed in the rear of the first heat storage device. Compared with the prior art, the heat storage type heating separating device has the advantages that the heat storage type heating separating device is safe and stabile in running, simple in structure and high in dry distillation efficiency, and obtained dry distillation gas phases are good in quality.
