The invention discloses environment-friendly batch-type multi-functional biomass pyrolysis equipment. The environment-friendly batch-type multi-functional biomass pyrolysis equipment comprises a screwfeeder, a cracking furnace, a blower, a buffer tank, condensers, oil-water separators, a product storage tank, a gas drying tank, a gas compressor, a gas storage tank, a vacuum pump, valves and connected pipelines. The environment-friendly batch-type multi-functional biomass pyrolysis equipment is characterized in that an inlet of the screw feeder is located at the uppermost end of a cylinder body of the cracking furnace, a discharge hole is formed in the bottom of the cracking furnace, and the discharge hole extends out of a hearth for 50-80cm; an upper exhaust port is formed in the top of the cracking furnace, and a lower exhaust port is formed in the top, extending out of the wall of the hearth, of the discharge hole; the upper exhaust port is connected to the upper condenser, and thelower exhaust port is connected to the lower condenser; the lower ends of the condensers are correspondingly connected to the oil-water separators through the pipelines; the lower ends of the oil-water separators are connected to the liquid storage tank through the pipelines; gas outlet pipes are disposed at the 2/3 height of the oil-water separators, and the gas outlet pipes are connected to thegas storage tank; and gas passes through the two exhaust ports on the cracking furnace, the condensers and the oil-water separators to form a circulation path. When biomass feedstock is cracked in thecracking furnace, a system maintains normal pressure or slightly positive pressure in the furnace, so that the cracking feedstock is cracked at a relatively stable cracking atmosphere, and the liquidproduct yield and selectivity are improved.
