The invention discloses a liquid separating membrane module with ultrasonic device, belongs to the technical field of liquid separating membrane module, and aim to overcome the disadvantage that the treating effect is not satisfaction and the treating efficiency is not high existing in the treating method for membrane pollution at precent. The invention comprises membrane module and an ultrasonic device comprising a power plug, power lead, a switching regulator, an ultrasonic generator, leads, a transducer and so on, which are connected with each other, and the transducer is mounted in the liquid of the membrane module. The use of the invention is using the ultrasonic to produce the strong bow wave in the water to break of the bond coat, crystal and dirt to resolve the problem of membrane pollution. The effect of the invention for treating the membrane pollution is remarkable, and the invention is used in kinds of liquid separating membrane module.
Description
technical field [0001] The invention relates to a liquid separation membrane module, in particular to a liquid separation membrane module provided with an ultrasonic device. Background technique [0002] Membrane separation technology, especially liquid membrane separation technology, as a high-tech, has developed rapidly since its rapid rise in the 1960s, and its application fields are very broad. Due to the relatively short development history of the membrane industry, there are still many technical problems to be solved. For example: treatment of membrane pollution during use. During the use of the membrane, external factors such as the formation of an adhesion layer on the surface of the membrane or the clogging of the membrane pores lead to changes in the performance of the membrane. Often when the pressure, flow rate, temperature and concentration of the feed liquid are kept constant, the percolation of the membrane rate decreased rapid...
