The invention provides saturated infiltration equipment, belonging to the technical field of pressure vessels and solving the problems that non-uniform and insufficient saturated infiltration of a coiled membrane material can exist and the saturated infiltration rate is low in an existing infiltration kettle. The saturated infiltration equipment comprises a kettle body, wherein at least one group of material placement assembly formed by two rotating shafts arranged in the kettle body vertically is arranged in the kettle body, a power mechanism for controlling the rotating shaft to rotate is arranged on each rotating shaft, and a gas inlet is formed in the kettle body; the saturated infiltration equipment also comprises a heat supply device and a circulating pipeline, wherein the heat supply device coats the outer wall of the kettle body, a circulating pump is arranged on the circulating pipeline, one end of the circulating pipeline is connected to the bottom of the kettle body and is communicated with the inside of the kettle body, and the other end of the circulating pipeline is connected to the outer side wall at the upper part of the kettle body and is communicated with the inside of the kettle body. The saturated infiltration equipment has the advantages of infiltration uniformity and high infiltration speed.
Description
technical field [0001] The invention belongs to the field of pressure vessels in the chemical industry, and in particular relates to a permeation device for fast and uniform dynamic saturation of a diaphragm material by a supercritical fluid. Background technique [0002] A supercritical fluid is a state that has both a high diffusion velocity like a gaseous state and a high solvency like a liquid state. The most widely used supercritical fluid is supercritical carbon dioxide (CO 2 ) and supercritical nitrogen (N 2 ). One can use supercritical CO 2 The solubility of the substance is more sensitive to the influence of temperature and pressure, by changing the CO in the supercritical state 2 Parameters such as temperature and pressure can achieve osmotic saturation of substances with different properties, or extract and separate different components of substances. Because supercritical carbon dioxide is non-toxic, non-flammable, safe to use, free of nitrates and heavy met...
