Problems solved by technology

[0004] Currently commonly used aeration and oxygenation devices have the following deficiencies: (1) the surface is easy to breed microorganisms and is easily blocked by impurity particles in the air and sewage; (2) the air distribution layer is thick, the air channel is long, and the pressure loss is large Increased energy consumption; (3) The mechanical strength is poor, and the increase in operating time will cause the device to age and shorten the service life of the aeration and oxygenation device

Abstract

The invention relates to a hollow fiber tube. The hollow fiber tube is woven by superfine fiber yarns with thickness of 0.001-0.01D and / or fiber bundles formed by the superfine fiber yarns; a plurality of flexible holes are formed in the tube wall of the hollow fiber tube obtained by weaving, wherein the flexible holes are formed by arranging the fiber yarn, the fiber bundle, the fiber yarn and the fiber bundle in parallel and / or crossing and superposing in a weaving process; the hole diameter of the flexible holes can be changed between 1 micro and 30 microns along with the difference of air pressure. The invention further discloses an aeration oxygenation device formed by the hollow fiber tube. The device has the remarkable advantages of high oxygen utilization rate (up to 25-40%), difficult block, high mechanical strength, long service life, convenient manufacturing, low cost and the like, and can be widely applied to the aeration oxygenation occasions of the fields such as chemical industry, environmental protection and fishery breeding.

Description

technical field [0001] The invention belongs to the technical field of aeration equipment, and in particular relates to a hollow fiber tube and an aeration and oxygenation device composed of the same. Background technique [0002] Aeration and oxygenation refers to the process of forcibly transferring the oxygen in the air to the liquid, the purpose of which is to obtain sufficient dissolved oxygen. By increasing the amount of dissolved oxygen in the water body, it provides oxygen for aquatic organisms to survive, mainly involving aquaculture, sewage treatment and other fields. Commonly used aeration methods include mechanical aeration, blast aeration, bubble aeration, surface aeration, etc. [0003] Aeration is an important process in the sewage aerobic biological treatment system. At present, the blower aeration system is widely used: the blower provides purified air, which is sent to the aeration device at the bottom of the biological pool through the pipeline system. T...
