Carbon gas and liquid joint production device using biomass pyrolysis and gasifying for teaching or scientific study

Abstract

The invention discloses a carbon gas and liquid joint production device using biomass pyrolysis and gasifying for teaching or scientific study. The carbon gas and liquid joint production device comprises a steam generator, a lower absorption type gasifying furnace, an upper absorption type gasifying furnace, a dry distillation furnace, gas pipelines, a purifying system, an induced draft fan, a gasflowmeter, a combined water seal tank and a combustor, wherein the purifying system comprises three condensing towers, two water scrubbing humidifying towers, a precipitating tank and three tar removal towers which are serially connected by the gas pipelines; the lower absorption type gasifying furnace, the upper absorption type gasifying furnace and the dry distillation furnace are respectivelyconnected with the front ends of the gas pipelines through pipelines; the purifying system is connected with the middle part of the gas pipeline, and the induced draft fan is serially connected with aconnecting pipeline of the purifying system; the tail end of each gas pipeline is sequentially connected with a gas flowmeter, a combined water seal tank and a combustor. The carbon gas and liquid joint production device has the advantages that one complete set of laboratory-level biomass gasifying and purifying equipment is provided; powder particles and biological oil can be separated, by the purifying system, from combustible gas generated after gasifying biomass fuel, and the clean combustible gas is obtained.

Description

technical field [0001] The invention belongs to the technical field of biomass energy equipment, in particular, it relates to a carbon-gas-liquid cogeneration device for biomass pyrolysis and gasification used for teaching or scientific research. Background technique [0002] Biomass energy ranks fourth in the world's total energy consumption after coal, oil and natural gas. At present, the world is in short supply of energy, and petrochemical energy reserves are limited, so it is urgent to develop new energy to achieve sustainable development. As a large agricultural country, my country produces up to 700 million tons of forestry waste and agricultural production residues each year, which contains huge biomass energy. Improving the utilization efficiency of biomass energy is of great significance to saving conventional energy, reducing environmental pollution, and protecting the ecological environment. People have developed many biomass energy utilization technologies, wh...
