According to the invention, the product disclosed by the invention has the characteristics of mobility, portability, simple operability and the like, is suitablefor being used in special environments such as fields, mountainous regions and the like, and particularly has outstanding functions aiming at the generation of a large amount of waste agricultural biochar after autumn harvest; and the carbonization furnace disclosed by the invention is reliable and safe in charcoal preparation process, high in preparation efficiency, low in cost, small in occupiedarea and portable, and can meet the requirement of field in-situ preparation of charcoal.

Description

technical field [0001] The invention relates to a field portable carbonization furnace for in-situ resource utilization of agricultural waste to prepare biochar in stages, in particular to a device for in-situ resource utilization of agricultural and forestry waste in the field, which belongs to the resource utilization technology of agricultural waste field. Background technique [0002] The total potential of comprehensive utilization of straw in China reaches 876 million tons, with remarkable environmental and economic benefits. However, in recent years, due to the lack of correct guidance for farmers and insufficient publicity, problems such as fires and air pollution caused by straw burning still occur from time to time. The cost of straw treatment is too high, and the stubble left by mechanical harvesting is high, which will affect the sowing of crops in the next season; the transformation of technology is not enough, and there is a lack of disposal technology, so it ...
