Abstract
The invention relates to a harmful solvent collection device for large-scale electrostatic spinning of nanofiber. The harmful solvent collection device comprises an active air supply system and a solvent collection system, the active air supply system comprises an active air supply motor, an active air supply pipeline and an airflow buffering plate, and the solvent collection system comprises an air exhaust pipeline, a primary temperature-control condensing cabin, a secondary temperature-control condensing cabin and a tertiary temperature-control condensing cabin. A circulating air system is adopted to actively and thoroughly eliminate an organic solvent in a spinning box, so that maintaining of solvent relative content in the spinning box is facilitated, and continuous and efficiency spinning is ensured; the organic solvent in the air exhaust pipeline is separated and collected efficiently and finely through the solvent collection system, so that the technical problems of electrospinning environment control difficulty, low nanofiber product stability and difficulty in collecting harmful solvents formed by spinning are expected to be solved, and the harmful solvent collection device has high engineering application value.
Description
technical field [0001] The invention relates to the technical field of textile machinery, in particular to a harmful solvent collection device for large-scale electrostatic spinning nanofibers. Background technique [0002] Electrospinning is currently the only general method that can spin continuous submicron fibers in batches. The diameter of submicron fibers prepared by electrospinning is usually 100-1000nm, the fiber size is small, the specific surface area is high, and the fiber morphology and composition It can be regulated by the flexible selection of spinning process parameters and polymers, making electrospun submicron fibers a research hotspot in the field of fiber science and engineering, and is widely used in filtration, energy, biomedicine, catalysis, waterproof and moisture-permeable, Oil-water separation and other fields. With the development of industrial technology, equipment such as multi-needle industrial electrospinning machines and needle-free free liqu...
