Description

Technical Field

[0001] The utility model relates to the technical field of recovery devices, in particular to a chloroform recovery device for bilirubin production. Background Art

[0002] Chloroform is an organic solvent that is often used in the extraction and separation of bilirubin. Bilirubin is a yellow compound produced in the human body and has important applications in the fields of medicine and biochemical engineering. At present, there are some different methods and devices for the recovery of chloroform, and one of the commonly used methods is to recover it using distillation technology. During the bilirubin production process, chloroform is evaporated and distilled, and then converted back into liquid through condensation. This distillation and condensation process can recycle and reuse chloroform, reducing resource waste and environmental pollution. Such a chloroform recovery device can effectively reduce the loss of chloroform and reduce the adverse effects on the environment. At the same time, it also helps to improve the efficiency and sustainability of the bilirubin production process.

The utility model heats bilirubin containing chloroform through a heating tank, and sends the liquid, foam, water vapor and chloroform vapor that are heated and boiled out of the tank into the gas-liquid separator, the liquid flows back to the heating tank for further heating, the water vapor and chloroform vapor enter the condensing mechanism for condensation, the chloroform vapor and the water vapor gas phase are condensed into a liquid phase, and most of the chloroform is recovered, and the recovered chloroform can be reused in the production of bilirubin, which is not only conducive to reducing production costs, but also avoids the chloroform gas from contacting with air during the heating process to produce phosgene to pollute the environment.
