Biomass and carbon-containing organic waste pyrolysis rotary furnace and pyrolysis product recovering system

Abstract

The invention discloses a biomass and carbon-containing organic waste pyrolysis rotary furnace. The biomass and carbon-containing organic waste pyrolysis rotary furnace comprises a cylindrical shell; the outer wall of the shell is connected with a supporting mechanism and a transmission mechanism; the two ends of the shell are rotatably connected with a furnace head cover plate and a furnace tail cover plate correspondingly through a gas seal type double-seal assembly; a flue gas collecting chamber is arranged on the furnace head side of an inner cavity of the shell; a combustion chamber is arranged on the furnace tail side; the flue gas collecting chamber and the combustion chamber are communicated through a fire pipe; the flue gas collecting chamber extends out of the furnace head cover plate through a flue gas discharging pipe; the combustion chamber is connected with a burner nozzle extending outside the furnace tail cover plate; the furnace head cover plate is connected with a feeding port communicated with the inner cavity of the shell; and the furnace tail cover plate is connected with a pyrolysis gas outlet pipe and a charcoal discharge port which are communicated with the inner cavity of the shell separately. The furnace head cover plate, the furnace tail cover plate, the inner cavity of the shell and the atmosphere are sealed through the gas seal type double-seal assembly, the materials are heated by a mode of self-heating and internally combusting the fire pipe, and the biomass and carbon-containing organic waste pyrolysis rotary furnace can be applied to new construction of a rotary furnace and is more suitable for transformation of an idle rotary kiln.

Description

technical field [0001] The invention relates to the field of rotary furnaces, in particular to a pyrolysis rotary furnace for biomass and carbon-containing organic waste, and also to a pyrolysis product recovery system using the pyrolysis rotary furnace. Background technique [0002] Petroleum, coal, and natural gas are still the three main energy sources in today's society. However, due to the massive exploitation of fossil energy, a large amount of greenhouse gas emissions have caused serious environmental pollution and global climate change. Biomass energy is the fourth largest energy source today, but the utilization of biomass resources is far from reaching the level of large-scale commercialization. Global biomass as energy recovery is still less than 4% of its total energy, and the potential is very large. It is estimated that the heat equivalent of the earth's annual water and terrestrial biomass production is 3×10 21 J is about 10 times the current total energy con...
