The invention discloses an integrated fiber pipe pretreatment enhanced hollow fiber membrane spinneret plate and a use method thereof, and relates to the technical field of hollow fiber membranes to solve the technical problems that osmosis and the wall thicknesses of the hollow fiber membranes cannot be effectively controlled, consequently, wall thickness uniformity is poor, and a device is complicated, high in cost and very difficult in operation in the prior art. The integrated fiber pipe pretreatment enhanced hollow fiber membrane spinneret plate comprises a pretreatment area, a cover plate, a primary distribution plate, a secondary distribution plate and a bottom plate which are sequentially communicated by a lacing hole. A pretreatment fluid inlet is formed in one side, far away fromthe cover plate, of the pretreatment area, a pretreatment fluid outlet is formed in one side, close to the cover plate, of the pretreatment area, particularly, a feeding port is formed in the primarydistribution plate, a material cavity is formed in the bottom plate, and a needle tube is arranged at the position of the material cavity.
Description
technical field [0001] The invention relates to the technical field of hollow fiber membranes, in particular to an integrated fiber tube pretreatment enhanced hollow fiber membrane spinneret and a use method thereof. Background technique [0002] With the increasingly serious pollution of China's water environment, membrane filtration technology is increasingly being used in the field of water treatment. Silk, water leakage and other problems, the commonly used reinforced hollow fiber membranes are mainly fiber tube reinforced hollow fiber membranes. [0003] In order to improve the strength of hollow fiber membranes and reduce the occurrence of broken filaments during operation, many companies have developed high-woven fiber tube reinforced hollow fiber membranes. The breaking force can reach more than 50N according to different materials. Fiber tube reinforced hollow fiber membranes In the production process, it is difficult to control the seepage material and inner surfa...
