Abstract

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.

Description

technical field [0001] The invention relates to the technical field of biomass energy and chemical processing, in particular to an environmentally friendly intermittent multifunctional biomass pyrolysis equipment. Background technique [0002] Petroleum, coal, etc. are the most important energy sources for human beings, and they also provide a large number of chemicals, but the earth's reserves are limited. With the large-scale exploitation and use of human beings, the resources are increasingly depleted. Biomass resources are renewable, and making full use of biomass resources is beneficial to the sustainable development of human beings. Furfural is a very important platform compound, and environmental protection and cheap production are the prerequisites for its large-scale application. [0003] Furfural is formed by hydrolysis of pentosan under the action of acid to generate pentose, and then dehydration and cyclization of pentose. The main raw materials for production ...
