Example Embodiment
[0012] Example 1
[0013] ①. Distillation of stock solution, 500L of wood vinegar stock solution collected from the chimney mouth of a charcoal kiln. Distillation still, under the condition of temperature 100 ℃, carry out distillation, make wood vinegar distillate 400L, remaining liquid 100L, the ratio of the two is 0.8:0.2;
[0014] ②, adsorption filtration, get above-mentioned ① wood vinegar distillate 400L, add 40kg active carbon adsorption 72 hours, through filtering, make wood vinegar filtrate 280L;
[0015] 3., adsorption filtration again, get above-mentioned 2. wood vinegar filtrate 280L, add 80kg high-temperature charcoal adsorption 12 hours, after filtering, make 240L colorless, odorless, nontoxic content be 100% wood vinegar.

Abstract
The invention belongs to the plant pyrolysis field, which particularly relates to a method for purifying plant fumigation matter. The invention is characterized in that the method for purifying comprises the following three steps: distilling primary liquid, adsorbing and filtering, and adsorbing and filtering again. The purifying method of the invention is simple, production cost is low, and degree of purity of products is high. Plant fumigation matter which is prepared by the invention is colourless and transparent, which has no peculiar smell and toxicity, and has the functions of killing viruses, sterilizing, killing acari, resisting oxidation, deodorizing, resisting moth, relieving itch and beautifying. The invention can be extensively applied in the fields such as food, medicine, daily chemical, environmental protection and the like.
Description
technical field [0001] The invention belongs to the field of plant pyrolysis, and in particular relates to a method for purifying plant fumigants. Background technique [0002] As we all know, plant fumigant is a smoke-water mixture collected by cooling the flue gas produced in the carbonization process of plants. Studies have proved that plant fumigant has the functions of killing viruses, sterilizing bacteria, deodorizing, relieving itching, preventing moths, beautifying and antioxidant, and Used in pesticides, fertilizers, etc. The main component of the plant fumigant stock solution is water, and the other components are more than 200 substances such as organic acids, tar, phenols, aldehydes, ketones, alcohols and heterocyclics; when the plant fumigant stock solution is used in food, medicine, environmental protection In the field of daily chemical products, it is necessary to remove soluble tar, phenol and formaldehyde which are harmful to human body. However, there ar...
