The invention discloses a production process of wood vinegar, which comprises two steps of crude and refined. Raw materials are peeled logs, cutting residues, roots, cutting residues, board skins and sawdust of broadleaf trees and coniferous trees. According to the existing charcoal making process, the kiln is fired. When the raw materials are carbonized into yellow smoke and the smoke temperature reaches 80℃, the acid-resistant porcelain tube is butted with the chimney to collect the wood retting liquid. Let the crude wood vinegar stand for more than 3 months, and filter it with gauze, membrane, gauze, inspection and perfusion. The biggest feature of the wood vinegar produced by the process of the invention is that it is a pure natural product, does not contain any artificially added ingredients, and has a wide application range. Inventor: Yu Zhiming. Invention patent application numbers: People's Republic of China (PRC) * * * and China Patent Office CN2007 100490.438+0.
The invention discloses a refining method of wood vinegar liquid or bamboo vinegar liquid, which comprises the following steps: introducing ozone into the wood vinegar liquid or bamboo vinegar liquid, treating the wood vinegar stock solution by using the strong oxidation effect of ozone and the micro-coagulation effect in the aqueous solution, and at the same time, effectively removing polycyclic aromatic substances and partially dissolving tar by using purification methods such as filtration and/or rectification, so as to significantly improve the purity of the wood vinegar liquid and obtain a colorless and transparent wood (bamboo) liquid. The method is simple in process, saves time, does not need any auxiliary materials and additives, improves the production efficiency and reduces the production cost, and meanwhile, the finished product has no residue and does not cause secondary pollution. abstract:
The refining method and use of wood vinegar liquid, a magical substance-wood vinegar liquid is extracted from carbon smoke with special equipment.
