Abstract

The invention provides a carbon dioxide supercritical fluid extraction device with heat recovery, which comprises an extraction tank, the output end of a first connecting pipe is in pipe connection with a separation box, the bottom end of the separation box is in pipe connection with a second discharge pipe, the output end of a second connecting pipe is in pipe connection with a carbon dioxide storage tank, and a third connecting pipe is in pipe connection with a booster pump. A heat exchanger is connected to the third connecting pipe and located on one side of the booster pump through a pipe, an extraction barrel is arranged in the extraction tank, a rotating mechanism is arranged in the extraction tank and located on the top of one side of the extraction barrel, a rotating ring is rotationally connected to the side wall of the extraction barrel, and a supporting ring is slidably connected between the bottom of the side wall of the extraction barrel and the inner wall of the extraction tank; and the carbon dioxide supercritical fluid extraction device has the beneficial effects that the extraction time and the gas-liquid separation time are shortened, the extraction efficiency is improved, the separation effect is improved, the carbon dioxide can be recycled, and the emission of the carbon dioxide is reduced.

Description

technical field [0001] The invention relates to the technical field of supercritical extraction equipment, in particular to a carbon dioxide supercritical fluid extraction device with heat recovery. Background technique [0002] The principle of supercritical carbon dioxide extraction and separation process is to use supercritical carbon dioxide to have a special dissolution effect on some special natural products, and to use the relationship between the dissolving ability of supercritical carbon dioxide and its density, that is, to use the influence of pressure and temperature on the dissolving ability of supercritical carbon dioxide. Carried out, the existing carbon dioxide supercritical fluid extraction device with heat recovery also has the following defects: [0003] In the extraction process of the existing carbon dioxide supercritical fluid extraction device with heat recovery, the extraction time is too long, so that the extraction efficiency is low, and the extracti...
