Problems solved by technology

At present, the air and water double washing technology is used, that is, the compressed air is first introduced into the separation membrane system, and the dirt on the surface of the membrane is removed by the impact of the air flow, and then the dirt is taken out of the separation membrane system by water, but the cleaning effect is not ideal. , is not the most effective way to reduce the contamination of the separation membrane, which shortens the subsequent chemical cleaning cycle and requires huge equipment and a large area

Embodiment 1

[0011] Such as figure 1 Shown: in the device of the present invention, there are water inlets 1 and sewage outlets 2 at different heights relative to the lower part of the hollow fiber separation membrane module 1, there are circulating water outlets 3 and water outlets 4 above the module 1, and the middle of the module 1 is equipped with five An ultrasonic energy exchanger 5 is fixed on the stainless steel shell 9 surface of assembly 1 with glue or magnet, and this shell 9 also can adopt other metal materials such as aluminum and aluminum alloy, because metal material is beneficial to the propagation of ultrasonic wave, in addition, in order to make reflection The wave effect is better, and the shape of its shell 9 mostly adopts a symmetrical geometric polyhedron (tetrahedron, hexahedron, octahedron). The present embodiment adopts a hexahedron, and the ultrasonic energy exchanger 5 and the ultrasonic energy generator 10 are connected together with the cable 7, and the separati...

Embodiment 2

[0013] Embodiment 2: five ultrasonic energy exchangers 5 are sealed and fixed on the bar steel by embedding, and then the bar steel is fixed on the inner side of the shell 9 of the hollow fiber separation membrane module 1. At this time, the shell 9 is not limited by the material. Can be non-metallic material. Other principles and structures are exactly the same as in Embodiment 1.

[0014] The invention can also be used for ultrasonic cleaning of biofilters and biofilter beds.

Abstract

An ultrasonic washing equipment for the hollow fibre separation membrane used to treat water features that multiple ultrasonic transducers are fixed to the metallic shell of said separating hollow fibre membrane assembly and the ultrasonic generator is fixed outside said membrane assembly and connected via cable to said transducers. The HF ultrasonic vibration waves are converted to HF mechanical vibration to form the cavitation effect for separating dirt from said membrane. The separated dirt is flushed out by water. Its advantages are high effect and low cost.

Description

Technical field: [0001] The invention belongs to a cleaning device for hollow fiber separation membranes, in particular to an ultrasonic cleaning device for hollow fiber separation membranes used in the treatment and reuse of wastewater in various fields. Background technique: [0002] Hollow fiber separation membranes are widely used in advanced treatment and reuse of urban sewage, industrial wastewater treatment and reuse, food, medical wastewater treatment and important raw material recovery, chemical industry and production wastewater in various fields. It has the advantages of operating at room temperature, saving energy, and reducing energy consumption. However, only after the hollow fiber separation membrane is thoroughly cleaned can the efficient operation and treatment effect of the system be guaranteed. At present, the air and water double washing technology is used, that is, the compressed air is first introduced into the separation membrane system, and the dirt o...
