Abstract
The invention discloses a supercritical carbon dioxide degumming reaction kettle for apocynum venetum bast fibers. The supercritical carbon dioxide degumming reaction kettle comprises a cylinder body, wherein a storage cage is arranged in the cylinder body; a storage cage central column is arranged in the middle of the storage cage; a carbon dioxide inlet, a reactant solution inlet and a motor transmission shaft inlet are formed in the bottom center of the cylinder body; a magnetic sealing device is arranged at the motor transmission shaft inlet; the carbon dioxide inlet and the reactant solution inlet lead to the interior of the storage cage central column; the storage cage can be driven to rotate by the storage cage central column. According to the degumming reaction kettle provided by the invention, the degumming reactant solution permeates through permeation holes uniformly formed in the central column, so that the degumming reactant and the apocynum venetum bast fibers are in full contact, the reactant required by degumming of the apocynum venetum bast fibers is guaranteed and the treatment process of the apocynum venetum bast fibers in supercritical carbon dioxide is also guaranteed; in addition, since the storage cage rotates in the degumming process, the defect of nonuniform degumming is overcome and the reaction speed is increased.
Description
technical field [0001] The invention relates to a reaction kettle for supercritical carbon dioxide degumming of apocynum bast fibers. Background technique [0002] Apocynum plants belong to the angiosperm phylum Apocynaceae, and mainly include three kinds of plants: Apocynum apocynum of the genus Apocynum genus Apocynum, white hemp and white hemp of the genus Lepidus. They are dominant plants for windbreak and sand fixation in the desertified grasslands of Central Asia. They have special ecological habits such as drought tolerance, salt tolerance, and strong fecundity. They are also Chinese medicinal materials, health products, and high-grade textile fiber raw materials. It has thin fibers, high strength, good air permeability, high refractive index, silky luster, and far-infrared function. The knitted underwear made of more than 35% apocynum fiber mixed with wool and cotton has the health care functions of sterilization, lowering blood pressure, relieving asthma and reliev...
