Description

一种高精度一体式中空纤维气体分离膜纺丝机A high-precision integrated hollow fiber gas separation membrane spinning machine

技术领域technical field

本发明涉及纺丝机领域,尤其涉及一种高精度一体式中空纤维气体分离膜纺丝机。The invention relates to the field of spinning machines, in particular to a high-precision integrated hollow fiber gas separation membrane spinning machine.

背景技术Background technique

中空纤维膜外形呈纤维状,内部中空。非对称结构中空纤维膜只有外层表皮具有分离作用,其余部分只起到自支撑作用。与其他形态的膜品种相比,非对称结构中空纤维膜组件分离效果好,效率高,填充密度大,占地小,投资收益明显,前景极为广阔。由于这些优点,目前用于气体分离的膜产品均采用此种形态的非对称中空纤维膜。因此,急需一种可连续自动生产气体分离膜的高精度中空纤维膜纺丝机。The hollow fiber membrane is fibrous in shape and hollow inside. In the hollow fiber membrane with asymmetric structure, only the outer skin has a separation function, and the rest only plays a self-supporting role. Compared with other types of membranes, the asymmetric structure hollow fiber membrane module has good separation effect, high efficiency, large packing density, small footprint, obvious investment income, and extremely broad prospects. Due to these advantages, the current membrane products for gas separation all use this form of asymmetric hollow fiber membrane. Therefore, there is an urgent need for a high-precision hollow fiber membrane spinning machine that can continuously and automatically produce gas separation membranes.

通过干-湿法纺丝工艺制造适用于气体分离领域的非对称中空纤维膜的技术难点是确保形成气体分离所需的特殊膜结构,也就是(一)非对称膜的表皮必须结构致密,且无缺陷,进而可有效分离不同种类的气体分子;(二)而该表皮的厚度需要在纳米尺度,从而减少气体分离通过的阻力;(三)和膜表皮同时形成的下部支撑层需要具有类似海绵的多孔形貌,从而进一步减少气体分子通过膜的阻力。而要同时实现如上三个非常苛刻的对膜形态的要求,需要对众多纺丝制膜过程中的操作参数进行非常精密的控制,主要的技术难点包括:膜液和芯液在进入纺丝头之前需将液体存在的微小杂质颗粒有效过滤,并脱除膜液和芯液中残留的微小气泡;膜液在注入纺丝头时需保持一定的温度以确保膜液以最优的流体形态从纺丝头中被挤出;膜液和芯液被从纺丝头挤出后,并非直接进入凝结池,而是先通过纺丝头下方一段空气再进入凝结池。该段空气的湿度会对气体分离膜产品的质量有很大影响,所以也需要对这一段空气的湿度进行控制。The technical difficulty of manufacturing asymmetric hollow fiber membranes suitable for gas separation by dry-wet spinning process is to ensure the formation of the special membrane structure required for gas separation, that is, (1) the skin of the asymmetric membrane must be dense in structure, and No defects, which can effectively separate different types of gas molecules; (2) The thickness of the skin needs to be at the nanometer scale, thereby reducing the resistance of gas separation and passage; (3) The lower support layer formed at the same time as the membrane skin needs to have a sponge-like surface. The porous morphology further reduces the resistance of gas molecules to pass through the membrane. However, in order to achieve the above three very stringent requirements for membrane morphology at the same time, it is necessary to carry out very precise control of many operating parameters in the process of spinning and membrane production. The main technical difficulties include: membrane liquid and core liquid enter the spinning head. Before, it is necessary to effectively filter the tiny impurity particles existing in the liquid, and remove the tiny bubbles remaining in the membrane liquid and the core liquid; the membrane liquid needs to maintain a certain temperature when it is injected into the spinning head to ensure that the membrane liquid is in the optimal fluid form from It is extruded from the spinning head; after the membrane liquid and core liquid are extruded from the spinning head, they do not directly enter the coagulation tank, but first pass through a section of air below the spinning head and then enter the coagulation tank. The humidity of this section of air will have a great influence on the quality of the gas separation membrane products, so it is also necessary to control the humidity of this section of the air.
