Abstract

The invention discloses a sanitary external pressure hollow fiber membrane assembly water collecting device, which is characterized by being provided with a cylindrical shell (1), wherein a cylindrical hollow cavity (2) is formed inside the shell (1), and forms a water flow channel; the top end of the shell (1) is provided with a water inlet / outlet (3); the water inlet / outlet (3) is communicated with the cylindrical hollow cavity (2); the inner wall of the cylindrical hollow cavity (2) is a smooth circular-arc curved surface; the bottom end (4) of the cylindrical hollow cavity is a concave semispherical surface; the outer side wall of the shell (1) is provided with a cementing port (5) for fixing the membrane end of a hollow fiber membrane along a cylindrical length direction; and the distance between the bottom end of the cementing port (5) and the bottom end (4) of the cylindrical hollow cavity is smaller than or equal to 1.5 times the diameter of the cylindrical hollow cavity (2). The water collecting device does not encourage the growth of bacteria, does not leave harmful substances, and has a simple structure and low cost.

Description

technical field [0001] The invention belongs to purification equipment in the field of water supply treatment, and in particular relates to an external pressure type hollow fiber membrane module water collection device with high sanitation level. Background technique [0002] Due to environmental pollution and water shortage in today's world, the rapid development of water treatment technology is forced. Due to the many advantages of hollow fiber membrane technology (including larger filtration area, easier reverse cleaning and lower cost, etc.), it is widely used in water supply treatment, sewage treatment and reclaimed water reuse. [0003] The structure of the hollow fiber membrane in the hollow fiber membrane technology is a hollow tube. The length of the hollow tube is much larger than its diameter, and it looks like a silk. Therefore, the hollow fiber membrane is vividly called a membrane filament. The tube wall of the membrane filament is a polymer film with a small ...
