Description

Technical Field

[0001] The invention belongs to the technical field of bamboo pyrolysis, and in particular relates to distillation equipment for preparing bamboo vinegar and a preparation process thereof. Background Art

[0002] Bamboo vinegar is a liquid substance obtained by collecting the gas produced by high-temperature decomposition of bamboo during the process of charcoal burning with bamboo, and cooling this gas at room temperature. Bamboo vinegar contains nearly 300 natural high-molecular organic compounds, including organic acids, alcohols, ketones, aldehydes, esters and trace alkaline components. Since ancient times, bamboo vinegar has been very famous for its deodorizing effect. It is often used to deodorize toilets. Nowadays, bamboo vinegar is mixed with livestock feed to reduce the odor of excrement. The output of bamboo vinegar varies with the type of bamboo, the moisture content of bamboo and the pyrolysis process. Its composition varies with the collection method, pyrolysis temperature, storage conditions, etc. Bamboo vinegar has many functions. It has good permeability and absorption to plant and animal tissues, and it also has the effect of eliminating the stench of livestock feces and kitchen garbage. Bamboo vinegar can also play a role in plant hormones. Adding a trace amount of bamboo vinegar to crops can promote plant rooting, germination, growth, and improve the taste of fruits. In short, it can be widely used in various fields such as agriculture, medical treatment, and health care.

[0003] The collection of bamboo vinegar should be carried out when the temperature of the chimney of the charcoal kiln is between 80°C and 150°C. In order to obtain pure bamboo vinegar, it is not suitable to use and should not use wood fuel in the process of charcoal burning bamboo. The bamboo vinegar collected from the bamboo charcoal kiln is a raw liquid, which can be refined by precipitation, filtration and distillation to obtain pure bamboo vinegar with quality that meets the requirements. In the preparation process of bamboo vinegar, distillation is a commonly used preparation method, such as a method for refining wood or bamboo vinegar disclosed in patent application number CN200710064490.1, by introducing ozone into the wood or bamboo vinegar, the wood vinegar raw liquid is treated by utilizing the strong oxidizing property of ozone and the micro-coagulation effect in the aqueous solution, and at the same time, purification methods such as filtration and / or distillation are used to effectively remove polycyclic aromatic substances and partially dissolved tar, so that the purity of the wood vinegar is significantly improved, and a colorless and transparent wood (bamboo) vinegar is obtained, so that the performance is stable during use;

[0004] The distillation equipment used in the existing bamboo vinegar preparation method is relatively scattered, the distillation processing efficiency is low, and industrialization is relatively difficult, which greatly reduces the production efficiency of bamboo vinegar. In addition, during the distillation process of bamboo vinegar, due to the multiple components of bamboo vinegar itself, the bamboo vinegar is prone to liquid stratification due to uneven distribution ratio before boiling, which affects the distillation effect of bamboo vinegar. Therefore, it is necessary to make improvements. Summary of the invention

[0114] S1 opens the feed port 100 to load the bamboo vinegar stock solution to be treated into the distillation kettle 1, and at the same time turns on the ozone generating unit 6 and the gas-liquid pump 50 to allow ozone to continuously enter the distillation kettle 1 through the circulation pipe 5 to mix with the stock solution;

[0116] S3 starts the main heating device 3 and the auxiliary heating device 7. The main heating device 3 directly heats the stock liquid, and the auxiliary heating device 7 generates a gas heat source. The gas heat source enters the stock liquid through the heat delivery pipe 71 and the heat exhaust loop pipe 72.

[0117] S4 waits for the stock solution to be fully heated and generate steam, then stops the auxiliary heating device 7, the main heating device 3 continues to operate, and the steam is condensed by the condensing mechanism 2 to finally form refined bamboo vinegar liquid.

[0118] Step S3 also includes:

[0119] S30 The electric heating tube 702 starts to generate heat, and the heat is transferred to the heat conducting plate group 8. Then the air supply unit 703 drives the external air to enter the tube body 700 from the air inlet 9. When the external air flows through the first heat conducting plates 80 and the second heat conducting plates 82, it absorbs the heat generated by the electric heating and converts it into a gas heat source, and finally enters the stock solution through the heat supply tube 71 and the heat exhaust ring tube 72.

[0120] S31 When the external air enters the pipe body 700 through the air intake part 9, the filter plate 91 filters the impurities contained in the external air, and the two air intake ends of the forked air intake pipe 90 always keep operating individually. When the filter plate 91 on the operating air intake end is blocked, the internal and external pressure difference sensing unit 93 senses the imbalance of the internal and external pressure difference, and controls the electric opening and closing damper 92 to operate, close the blocked air intake end and open the other spare air intake end;

[0121] S32 After the blocked air inlet end cup is closed, the driving member 11 drives the cleaning roller 10 to clean the filter surface of the filter plate 91 in the air inlet end, and after the cleaning is completed, it serves as a spare air inlet end.

The distillation equipment has a high degree of integration and is convenient for industrial production. At the same time, the auxiliary heating device 7 and the main heating device 3 cooperate to improve the distillation efficiency of the bamboo vinegar liquid, thereby improving the production efficiency of the bamboo vinegar liquid. At the same time, when the auxiliary heating device 7 performs auxiliary heating on the bamboo vinegar liquid through the gas heat source, the gas heat source can drive the bamboo vinegar liquid to roll, thereby preventing the bamboo vinegar liquid from generating liquid dust due to standing still in the early stage of heating, thereby improving the distillation effect of the bamboo vinegar liquid.
