Abstract

A device for recycling rectification tail gas through an evaporator condensation method is disclosed. The device comprises a base, wherein a recovery column is arranged on the base, an evaporator is arranged at the bottom in the recovery column, a condensation bin is arranged at the top of the recovery column, the top of the evaporator is communicated with the condensation bin, a medium pressurizing mechanism is arranged on the base, and the medium pressurizing mechanism is communicated with the evaporator. The invention provides the device and a method for recovering rectification tail gas byan evaporator condensation method. According to the device, the medium pressurizing mechanism is ingeniously designed, waste gas containing rectification tail gas is pressurized through the medium pressurizing mechanism, the air pressure in the evaporator is increased, gasification and temperature rise of the rectification tail gas in the evaporator are facilitated, the rectification tail gas enters the condensation bin to be condensed in the high-temperature and high-pressure state, and target substances in the rectification tail gas are obtained. High-pressure nitrogen and rectification tail gas are further mixed, the air pressure in the evaporator is improved, and the stable physicochemical property of the nitrogen ensures the safety of pressurization.

Description

technical field [0001] The invention belongs to the technical field of rectification tail gas recovery and treatment, and specifically relates to a device and method for recovering rectification tail gas by evaporator condensation. Background technique [0002] Distillation is a separation process that uses the different volatilities of the components in the mixture to separate the components. Commonly used equipment includes plate distillation towers and packed distillation towers. The principle and equipment process of precision distillation are the same as ordinary distillation, except that the relative volatility of the components in the system to be separated is small (<1.05~1.10), so high-efficiency precision packing is used to achieve the separation of the components to be separated Purify. In natural essential oils, the raw material for the production of isolated spices, isomers often coexist. For example, citronellol and rhodinol that coexist in natural essentia...
