Description
Technical Field
The invention relates to the technical field of wood carbonization, in particular to wood carbonization equipment.
Background
Pine wood nematode (Bursaphelenchus xylophilus) disease is a major plant epidemic situation, which is introduced into China in 1982, 7000 or more thousand strains of pine trees are fatally killed, and the safety of 6 hundred million or more acres of pine forest in China is threatened. The pine wood nematode has strong reproduction capacity and can kill trees quickly, the pine trees can die 40 days after infection, and the forest can be destroyed in 3-5 years. By the end of 2020, epidemic situation in China relates to 18 provinces and cities, 726 counties are total, the epidemic situation occurrence area is 180.92 ten thousand hectares, and the number of pine trees died of illness is 1947.03 ten thousand. The epidemic areas in Jiangxi, Guangdong, Zhejiang, Fujian, Anhui, Chongqing provinces (cities) have an incidence area of over 600 hectares. The development of the control technology of pine wood nematode is imminent.
The wood epidemic treatment and high-value utilization technology is the key for controlling the spread of the pine wood nematode disease and changing waste into valuable. At present, the treatment mode of the epidemic trees is mainly in-situ incineration and fumigation treatment. The treatment mode can effectively block the problems of loss, hiding, stealing, harm removal and the like caused by the descending of the epidemic trees, but the treatment mode is easy to cause fire disasters in the mountain forest and waste wood resources. The fumigation treatment has strong geographical limitation, can not kill the pine wood nematodes fundamentally and is not beneficial to large-area popularization. China urgently needs key technologies and equipment for processing and high-valued utilization of epidemic trees in forestry. The BA-1 type movable carbonization furnace was introduced by the national institute of forest and Integrated research in agriculture, forestry, aquatic products and provinces of Japan as early as 80 years abroad. Canadian scholars have proposed a vehicular pyrolysis device of inner loop bed type, and the separation has pyrolysis district and combustion area in same reactor cavity, and the inlayer is the combustion area, and the skin is the pyrolysis district, and the pyrolysis district is equipped with the promotion stand pipe that passes the combustion area bed, and pyrolysis district bed material and living beings raw materials constantly pass through the combustion area along the riser under the promotion of fluidizing gas and obtain the heat to realize the living beings pyrolysis. In addition, the researchers have proposed a compact type double-bed type vehicle-mounted pyrolysis apparatus. Bed material exchange between the double beds is realized by utilizing a screw at the bottom of the double fluidized beds, and biomass charcoal generated by the pyrolysis zone is pushed into the combustion zone to be combusted, and then pushed into the combustion zone to be combusted. And then the bed material is recycled to return heat to the pyrolysis zone to maintain the pyrolysis reaction. The double-bed type mobile pyrolysis apparatus realizes autothermal operation, but the reactor volume is large, and nitrogen gas needs to be reserved for purging and blowing. In 90 s, agricultural and forestry wastes are carbonized by using small-sized carbonization furnaces in various places in China, combustible gas in collected gas accounts for about 60% of the collected gas, the carbon yield is as high as 40%, and the fixed carbon content of woody plants after carbonization is higher than that of herbaceous plants. Meanwhile, students apply the mobile carbonization furnace to forest work, and the burned charcoal reaches international standards. In recent years, small continuous feeding straw black carbonization devices are developed, and combustible gas generated in the thermal degradation process is recycled and utilized.
In summary, the existing wood epidemic treatment and utilization technology is not mature, and the following difficulties mainly exist: the pine wood nematode can not be killed from the source, the wood resources can not be effectively utilized, and the secondary pollution is caused in the treatment process.
