Abstract

The invention discloses an ultrafiltration membrane filtering device. The ultrafiltration membrane filtering device comprises a shell, a central tube, a plurality of membrane wires and a plurality of ultrasonic probes, wherein the shell is a hollow tube which has an Achimedean spiral plane structure; a first opening is formed in one end of the outside of the shell; a second opening is formed in one end of the inside of the shell; the central tube is a hollow tube which has an Achimedean spiral plane structure and is coaxially arranged in the shell; one end of the outside of the central tube penetrates out of the first opening so that sewage can be guided in the central tube; one end of the inside of the central tube is closed; a plurality of through holes are formed in a wall of the central tube; each of the membrane wires has an Achimedean spiral plane structure; the membrane wires are arranged in a gap between the shell and the central tube; one end of the outside of each membrane wire is closed; one end of the inside of each membrane wire penetrates out of the second opening so that pure water can be guided out of the device; and the ultrasonic probes are fixed on the outer surface of the shell and are connected with an ultrasonic generator through leads respectively. The ultrafiltration membrane filtering device is compact in structure, high in space utilization rate and high in sewage treatment efficiency.

Description

technical field [0001] The present invention relates to ultrafiltration membranes. More specifically, the present invention relates to an ultrafiltration membrane filtration device for water treatment. Background technique [0002] As a new type of fluid separation technology, the ultrafiltration membrane filtration device can effectively remove particulate matter in water, reduce water turbidity, and remove macromolecular organic pollutants. Microorganisms such as bacteria and even viruses. Moreover, the ultrafiltration membrane filtration device can be operated at normal temperature without phase change. [0003] However, the current ultrafiltration membrane filtration devices are not compact enough in structure, poor in pressure resistance, high in energy consumption, and occupy a large space. Moreover, long-term use will cause membrane fouling, greatly reduce the amount of liquid permeation, and lead to a decline in water treatment quality and efficiency. In addition,...
