Rotary agricultural and forestry waste continuous pyrolysis device with heat energy self-supply function

Abstract

The invention relates to a rotary agricultural and forestry waste continuous pyrolysis device with a heat energy self-supply function. The rotary agricultural and forestry waste continuous pyrolysis device is characterized by comprising a crushing feeding device, a rotary pyrolysis reactor, a pulse combustion heat supply device, a coke collecting device, a heat exchange device and a control system, materials are continuously fed into the pyrolysis reaction chamber, a certain angle is formed between the pyrolysis reactor and the horizontal plane, and the rotary reactor can make the materials roll up and down and move downwards. Pyrolysis gas generated in the material pyrolysis process provides fuel for the pulse combustor, combustion smoke provides pyrolysis media and heat for the pyrolysisfurnace, and pyrolysis gas combustion heat supply and combustion smoke cyclic utilization are achieved. The design structure is compact, feeding, pyrolysis, heating, collection and heat exchange devices are combined, and continuous and efficient pyrolysis and heat energy self-supply of waste can be achieved; and meanwhile, the heating device is communicated with the pyrolysis area, gas obtained after natural gas and pyrolysis gas are combusted serves as a pyrolysis medium, no extra pyrolysis medium is needed, and the operation cost of the pyrolysis system is greatly reduced.

Description

technical field [0001] The invention belongs to the field of biomass pyrolysis, and relates to a biomass pyrolysis device, in particular to a rotary continuous pyrolysis device for agricultural and forestry waste with self-supply of heat energy. Background technique [0002] At present, the energy crisis is a common problem faced by the world today. The excessive use of fossil energy has caused pollution and damage to the earth's ecological environment. The task of finding a clean alternative energy source is also imminent. As the fourth largest energy source on the earth, biomass energy resources are abundant, and its reserves are second only to coal, oil and natural gas. It is one of the most suitable alternative energy sources for fossil energy. Therefore, the development of biomass energy technology has become a hot spot in the research and development of countries. Become an important way to solve energy and environmental problems. [0003] There are more than 700 mill...
