Abstract

The invention relates to a production method for co-production of bamboo charcoal and bamboo vinegar. The production method includes the following steps that S1, raw materials are selected; S2, moso bamboos are crushed, wherein the moso bamboos with the branches and leaves are crushed into 3-5 mm blocks according to the technological requirement, soaking with a pretreatment solution is conducted for 1-2 h, drainage is conducted, and then the objects are pre-dried at 60-70 DEG C until the water content is 20-25 % and sent to a pre-heating mechanism through a feeding mechanism, the pretreatmentsolution is prepared from, by weight, 3-8 % of water insoluble dextran, 10-15% of sodium hydrogen carbonate, 2-5% of aminophylline and the balance deionized water; S3, pre-heating is conduced; S4, pyrolysis is conducted; S5, carbonization is conducted; S6, bamboo vinegar purification is conducted, wherein bamboo vinegar obtained in the step 3 and bamboo vinegar obtained in the step 4 are mixed, anadsorption treatment agent is added in the mixture, then the mixture is stirred evenly, treated for 0.5-1 h and fully filtered, and the finished product of bamboo vinegar is obtained, the adsorptiontreatment agent refers to modified sepiolite powder. The production efficiency is high, the product yield is high, the degree of automation is high, and through organic coordination of the various mechanisms, the requirement of industrialized co-production of bamboo charcoal and high-quality bamboo vinegar can be met.

Description

technical field [0001] The invention relates to a production method and equipment for coproduction of bamboo charcoal and bamboo vinegar, belonging to the technical field of bamboo charcoal and bamboo vinegar processing. Background technique [0002] As activated carbon is widely used in environmental protection, chemical industry, food, medicine, water treatment and other fields. The performance of activated carbon using coal as raw material is limited, and it can no longer meet the growing demand for activated carbon in different fields. Therefore, bamboo activated carbon with excellent performance is produced and applied in large quantities. However, due to the backward technology, a large amount of volatiles produced after bamboo pyrolysis in the production process of bamboo activated carbon have not been effectively recycled, which not only caused a huge waste of energy, but also caused environmental pollution. Studies have shown that during the pyrolysis and carboniz...
