Embodiment 1

[0015] The present invention comprises the following steps:

[0016] S1. Raw material pretreatment: crush the straw with a grinder;

[0017] S2. Segmented pyrolysis: the crushed straw in step S1 passes through the drying zone (120°C-200°C), the pre-pyrolysis zone (200°C-400°C), the main pyrolysis zone (400°C-500°C) ℃), calcination zone (500℃-600℃), cooling zone (<400℃) for heating, and ensure that the atmosphere is nitrogen during the heating process;

[0018] S3. Separation and collection of carbon black: the solid product obtained in step S2 is successively sedimented, cooled, and collected to obtain carbon black.

[0019] S4. Dust removal: the flue gas product obtained in step S2 is sequentially passed into a cyclone dust collector and a high temperature dust collector for dust removal;

[0020] S5. Separation and collection of tar: pass the flue gas after dedusting in step S4 into the condenser, liquefy the tar in the flue gas, separate it from the gas, and enter the tar...
