Embodiment 1
[0045] (1) Crush canes, rhizomes and roots to obtain scraps:
[0046] After removing the leaves, tender stems and tidbits of the potato, the rattan, rhizomes and roots are crushed with a wood chipper to obtain fragments, which are put into a rolling cage sieve, and the impurities are removed by rolling through the rolling cage sieve;
[0047] (2) Drying scraps:
[0048] The heat of the stove is sucked into the drying cylinder by the induced draft fan, and the crushed materials are twisted into the drying cylinder by the cage conveyor and dried;
[0049] (3) Two separations to remove ash and water:
[0050] Under the action of the induced draft fan, the dried crushed material is sent to the cyclone separator for two separations, the first separation removes the ash, and the second separation removes the water;
[0051] (4) Make semi-finished machine-made charcoal:
[0052] Send the separated fragments to the rod making machine through the twisted cage conveyor to make semi-f...
Embodiment 2
[0060] Production is carried out as in Example 1, wherein in step (5), dry distillation is carried out for 11 hours, and then the furnace is closed for 15 hours for cooling.
Embodiment 3
[0062] Production is carried out by the method as in Example 1, wherein in step (5), dry distillation is carried out for 10.5 hours, and then the furnace is closed for 14.5 hours for cooling.
[0063] In step (8), after adding the clarified liquid of lime water to the pulverized leaves, tender stems and flocs of the fallen sunflower potato, the clarified liquid is sent to a biogas digester to produce biogas.

Abstract
The invention discloses a method for producing environment-friendly mechanism charcoal and coproducing wood tar oil and biogas by using anredera cordifolia. The method comprises the following steps: (1) crushing rattans, rhizomes and roots so as to obtain crushed materials; (2) drying the crushed materials; (3) carrying out two-times separation so as to remove ash content and moisture; (4) preparing a mechanism charcoal semi-finished product; (5) feeding the mechanism charcoal semi-finished product into a carbonization furnace and carrying out dry distillation; (6) coproducing the wood tar oil and wood gas; and (7) coproducing biogas. The method has the advantages that the wood crushed materials can be obtained at high efficiency by using a hammer mill for crushing the rattans, the rhizomes and the roots and then drying; the dry distillation time is appropriate, and the charcoal finished product has good mechanical strength, high carbon content and high heat value and relatively long burning time; the wood gas is reused as fuel, so that the environment-friendly production is realized, and the production cost is also reduced; exceedingly-rich raw materials are supplied for the production of the mechanism charcoal, the wood tar oil and the biogas, and the disaster problem caused by alien invasive plants is also solved; and each ton of mechanism charcoal semi-finished products can be used for generating 200-250kg of wood tar oil during dry distillation.
Description
technical field [0001] The invention relates to a method for co-producing wood tar and biogas by using fallen sunflower potatoes to produce environmental protection mechanism charcoal. Background technique [0002] Luokui potato, also known as rattan notoginseng, rattan notoginseng, Chuanqi, Yang Luokui, scientific name is Anredera cordifolia (Tenore) Steenis, English name is Madeiravine, Mignonettevine, Bridalwreath, belongs to the sunflower family plant, is a perennial herb Twining evergreen large vines, up to more than 10 meters long. Luokui potato is native to tropical and subtropical regions of South America. It was introduced from Southeast Asia in the 1970s. It is often cultivated as ornamental plants or medicinal plants in various places. It is cultivated in southern my country to northern China, and survives the winter as rhizomes in Beijing and Tianjin. , is currently wild in Chongqing, Guizhou, Hunan, Guangxi, Guangdong, Hong Kong, Fujian and other places. The sm...
