AI Technical Summary

Technical Problem

In the existing technology, the process of separating and purifying nicotine from tobacco waste in the tobacco industry requires the use of strong acids and strong bases, which makes the process complicated and poses an environmental pollution risk.

Method used

An apparatus for preparing nicotine from recycled tobacco waste includes a pyrolysis unit, a pyrolysis gas condensation unit, a distillation unit, and a distillation condensation unit. Nicotine is separated and purified under conditions without strong acids or bases through a two-stage condensation and distillation process. The separation efficiency is improved by utilizing the baffle structure of the pyrolysis gas condensation unit and the jacketed heating belt of the distillation unit. The rapid liquefaction of nicotine is achieved by combining a vacuum pump and a refrigerant.

Benefits of technology

It achieves simple and efficient nicotine separation, is environmentally friendly, and has a nicotine yield of no less than 1%, improving production safety and efficiency while reducing energy consumption.
