The embodiment of the present invention provides a device for in-situ carbonization of biomass and its use method, which relates to the field of biochar manufacturing equipment. The carbonization device includes: a combustion furnace, a furnace cover, a water spray device and a flue gas circulation device. The top of the combustion furnace is provided with an upper port; the furnace cover is closed on the upper port of the combustion furnace; the water spray device is connected with the furnace cavity of the combustion furnace for spraying water; the flue gas circulation device communicates with the furnace chamber, and is used to mix the flue gas in the upper part of the furnace chamber with the outside air and transport it to the lower part of the furnace chamber. The on-site biomass carbonization device provided by the embodiment of the present invention can convert biomass into biochar on the spot, reduce the transportation cost of biomass, and reduce the production cost of biochar; because the smoke is recycled during the production process , to avoid the smog in the process of charring and reduce environmental pollution.
Description
technical field [0001] The invention relates to the field of biochar manufacturing equipment, in particular to an on-site charcoal-forming device for biomass and a method for using the same. Background technique [0002] As a new type of soil remediation material, biochar can effectively improve soil fertility, increase soil field water holding capacity, passivate heavy metals in soil, and even be used as a matrix material for slow and controlled release fertilizers, with broad application prospects. [0003] At present, most of the biochar production methods are the traditional collection and transportation of agricultural and forestry wastes (such as straw, etc.) to the burning site, and then biochar production. Due to the high construction and operation cost of large-scale biochar production equipment, large floor area, and light and bulky raw materials, the collection and transportation costs have greatly increased; in agricultural parks, a variety of crops are generally...
