Problems solved by technology
[0004] When using the Flath device, the mixing process of the extraction solvent vapor and the vapor of the sample solution to be purified basically occurs in the condensation chamber 1 within the length of the condensation pipe 6, so in order to ensure sufficient mixing and condensation, the condensation pipe 6 must be made It is long enough so that the steam of the sample solution to be purified must climb to a considerable height (450mm) to reach the top of the condensation chamber 1 and mix with the extraction solvent vapor, which affects the smooth progress of the simultaneous distillation and extraction process, and the longer condensation tube 6 makes the device more stable. The complexity of the structure increases; in this device, the condensation process begins as soon as the extraction solvent vapor and the sample solution vapor to be purified enter the condensation chamber 1, and they are not sufficiently mixed in the future, which is detrimental to the extraction effect

The invention provides an improved simultaneous distillation extraction apparatus which comprises a condensation cavity, a first branch tube and a second branch tube which are communicated with the condensation cavity, as well as a gas-liquid mixing tube which is communicated with the condensation cavity; and the first branch tube and the second branch tube are communicated with the condensation cavity by being communicated with the gas-liquid mixing tube respectively. As the gas-liquid mixing tube is arranged, extraction solvent vapor and sample solution vapor to be purified are mixed in the gas-liquid mixing tube, and then enter the condensation cavity from the gas-liquid mixing tube, thus preventing the extraction solvent vapor and the sample solution vapor to be purified from being respectively condensed into liquid without being fully mixed, and improving the working efficiency; meanwhile, shorter condensation tube can be adopted to reduce the climbing height of the extraction solvent vapor and the sample solution vapor to be purified, thus the structure of the apparatus is simplified and miniaturized.
Description
technical field [0001] The invention relates to a simultaneous distillation and extraction device, in particular to a simultaneous distillation and extraction device with higher efficiency. Background technique [0002] When separating and purifying samples, people usually use distillation and extraction processes to obtain high-purity products. Distillation and extraction can also be combined to mix and condense the distillation steam and extraction solvent vapor. The Likens-Nickerson simultaneous distillation extraction device is such a purification equipment that can combine the distillation process and the extraction process into one. Because it can reduce the use of a large amount of solvents, and can carry out the distillation process and the extraction process at the same time, shorten the purification time, and improve the purification efficiency, it has been well known by the fragrance industry since it came out in 1966. In the process of use, people have made many...
