Abstract

The invention discloses an ultrafiltration membrane deaerating unit which is high in deaerating efficiency and effective in deaerating and enables ultrafiltration membrane filtrating precision to be improved and blow holes in spinning to be avoided. The ultrafiltration membrane deaerating unit is capable of removing bubbles once and is widely applicable to feed liquid in wide viscosity range. The ultrafiltration membrane deaerating unit comprises a tank (1) and an upper cover (2). The tank (1) and the upper cover (2) are connected to form a closed space (100). A feed pipe component (3) is connected to the center of the top of the upper cover (2). A liquid outlet (14) is reserved at the center of the bottom of the tank (1). An umbrella-shaped deaerator (6) is arranged on the inner upper portion of the closed space (100) and comprises an overflow groove (61) at the center of the top and a deaeration leveling umbrella-shaped face (62) around the overflow groove (61), and the overflow groove (61) corresponds to a feed inlet of the feed pipe component (3). A slanting deaeration membrane-drawing slope is reserved on the lower middle of the inner wall of the tank (1). The ultrafiltration membrane deaerating unit is widely applicable to the field of ultrafiltration membrane preparation.

Description

technical field [0001] The invention relates to a degassing device, in particular to a degassing device for degassing polymers in the process of preparing ultrafiltration membranes. Background technique [0002] Ultrafiltration membrane is a microporous filtration membrane with uniform pore size and rated pore size range of 0.1-0.02 microns. Appropriate pressure is applied to one side of the membrane to screen out solute molecules smaller than the pore size to separate particles with a molecular weight greater than 5 Daltons and a particle size greater than 2 to 20 nanometers. The ultrafiltration membrane is one of the earliest developed polymer separation membranes, and the ultrafiltration device was industrialized in the 1960s. The industrial application of ultrafiltration membrane is very extensive, and it has become one of the new chemical unit operations. It is mainly used in the separation, concentration, purification of biological products, pharmaceutical products an...
