DETAILED DESCRIPTION - Solid regenerative ball heating system of biomass pyrolysis liquefaction device, comprises a regenerative ball heating device, a feeding device, a reactor, a separating device, an ash box (1), a pyrolysis gas processing device, and a ball lifting device (3), where a first heat storage ball outlet (4) is connected to the feeding device, and a reactor discharging port is connected to the separating device. The separating device is connected to the ash box, and its top part is connected with the pyrolysis gas processing device (2) through a pyrolysis gas outlet (5), where a second ball outlet is arranged at lower end side wall of the separating device and is connected with an input end of the ball lifting device, and output end of the ball lifting device is connected to the regenerative ball heating device. The reactor is a tube type reactor composed of an inner pipe and an outer pipe, where the inner pipe is provided with two open ends respectively connected to an outlet and a feeding inlet of the separating device, the outer tube is closed at both ends, side wall of the outer tube end is provided with a hot air outlet and lower end of the outer tube is provided with a hot air inlet. The reactor is divided into three parts along axial direction from top to down, which are a straight part, an arc-shaped transition part and an inclined straight tube part, where axis of the straight part is at an inclined angle of 120 degrees. The separating device comprises a separation box and a sieve plate obliquely arranged in the separation box, where the inner tube is connected to the separation box, the angle alpha between the sieve plate and the inner tube is 40-60 degrees, and angle between the horizontal and the sieve plate is 50 degrees. The sieve plate lower end is connected with the second ball outlet, and the inner pipe is inserted into the separation box upper end by a pipe length of 300 to 400 mm. The sieve plate is connected with the separation box, and it has carbon ash dropping ports.
