Hollow tubular water processing membrane element ultrasonic wave descaling device, and method thereof

Abstract

The invention relates to a hollow tubular water processing membrane element ultrasonic wave descaling device, and a method thereof. The hollow tubular water processing membrane element ultrasonic wavedescaling device is capable of solving problems in the prior art that conventional water processing tubular membrane element ultrasonic wave descaling device structures are complex, and ultrasonic wave energy concentration is difficult to realize. The hollow tubular water processing membrane element ultrasonic wave descaling device comprises an ultrasonic wave generation unit, a control unit, anda walking servo unit; the walking servo unit comprises a tank body and two semi-circular embracing rings; the upper ends of the two semi-circular embracing rings are connected using an articulated shaft; the articulated shaft is designed to be vertical the corresponding end surfaces of the semi-circular embracing rings; the lower ends of the two semi-circular embracing rings are provided with buckle members; the two semi-circular embracing rings are detachably connected using the buckle members so as to form a closed ring can be opened and closed; each semi-circular embracing ring is composedof a telescopic joint and two arc-shaped segments connected with the two ends of the corrugated telescopic joints; an amplitude transformer rod and a high frequency hoodle contact head are arranged in the inner cavity of each corrugated telescopic joint. The hollow tubular water processing membrane element ultrasonic wave descaling device is suitable for cooperation utilization with ultrafilter membrane reverse osmosis membrane water processing equipment, and can be widely used in processing of various water.

Description

technical field [0001] The invention relates to an ultrasonic descaling device and method for a hollow tubular water treatment membrane element. Background technique [0002] At present, membrane treatment technology is widely used in water treatment in many fields such as urban sewage treatment and reuse, industrial wastewater treatment and reuse, and concentration and reduction of high-salt wastewater, among which tubular membranes are the most widely used. Although the membrane treatment technology has the advantages of operating at room temperature, energy saving, and high separation efficiency, it also has problems such as easy fouling and fouling. Only after the membrane elements are thoroughly descaled and cleaned can the efficient operation and treatment effect of the system be guaranteed. . [0003] The traditional anti-scaling and descaling methods in membrane treatment focus on the improvement of influent water quality, which is to improve the influent water qual...

AI Technical Summary

Problems solved by technology

The disadvantage is that the cleaning method is single (only ultrasonic waves are used), and there are many devices (each membrane element needs to be equipped with a set of ultrasonic devices), which brings inconvenience to later maintenance and replacement.

Its disadvantage is that the installation position is fixed, and it cannot be moved outside the tube to apply ultrasonic waves.
