Device for testing antifouling property of hollow-fibre membrane

Abstract

The invention discloses a device for testing antifouling property of a hollow-fibre membrane. The device comprises an end cap, and a hollow hole arranged in the end cap, wherein a charging pump and a feed liquid circulating barrel for forming a circulation loop are connected with two ends of the hollow hole; a plurality of connecting pipes are arranged at the two ends of the hollow hole, and between the charging pump and the feed liquid circulating barrel; a pressure gauge is arranged on each connecting pipe, and valves are also arranged at two ends of the hollow hole on the end cap. By adopting the device for testing the antifouling property of the hollow-fibre membrane, the fibre membrane to be tested is arranged inside the hollow hole in a testing process, and liquid inside the feed liquid circulating barrel is driven to flow circularly through the charging pump; a work scene of the fibre membrane in actual operation can be simulated by controlling the entire internal pressure of the device, and the antifouling property is test. Therefore, the device is simple in operational process, convenient and fast in measurement process, and accurate in measured numerical value. Thus, the device disclosed by the invention is applied to the field of an experiment test.

Description

technical field [0001] The invention relates to an experimental test device, in particular to a device for testing the anti-pollution performance of fiber membranes. Background technique [0002] Membrane separation technology, as a new high-efficiency separation technology, has broad application prospects in the field of water pollution control. At present, my country's membrane materials are mainly imported products, and there are few products with independent intellectual property rights, most of which are imported foreign products and technologies. [0003] Membrane separation technology can not only be used as a pretreatment method for other water treatment processes, but also for deep purification of water bodies. The effluent can be directly drunk, providing safe and healthy drinking water. There has been no standard for related analysis and testing equipment. [0004] At the same time, the anti-fouling performance is an important performance index of the hollow fibe...

[0003] Membrane separation technology can not only be used as a pretreatment method for other water treatment processes, but also can be used for deep purification of water bodies. The effluent can be directly drunk, providing safe and healthy drinking water. There has been no standard for related analysis and testing equipment

[0004] At the same time, anti-fouling performance is an important performance index of hollow fiber membranes, but there is still no commercial equipment for testing the anti-fouling performance of hollow fiber membranes.
