Ultrasonic cleaning reverse osmosis membrane

Abstract

The reverse osmosis membrane comprises a reverse osmosis membrane shell tank, a reverse osmosis filter membrane, an ultrasonic probe and an ultrasonic generator, the reverse osmosis filter membrane is arranged in the reverse osmosis membrane shell tank, the ultrasonic probe is arranged below the reverse osmosis filter membrane, and the ultrasonic generator is arranged on the reverse osmosis membrane shell tank. The ultrasonic probe is connected with the ultrasonic generator. By adopting the technical scheme, the ultrasonic cleaning reverse osmosis membrane which is simple and convenient to operate is prepared. The problems that the operation process is tedious, the cleaning time is long, the cleaning efficiency is low, equipment is damaged and replaced due to long-time use, some labor and materials are wasted and the like in an old method are solved more effectively. The cost is saved, the efficiency is improved, dirt on the membrane can be quickly and efficiently cleaned, and unnecessary waste is avoided. Equipment and an inner container film do not need to be replaced, and equipment cost and material cost are saved. The cleaning time is short, the waiting time is short, cleaning is completed in one step, and the drainage flow is increased more effectively.

Description

technical field [0001] The invention relates to the field of reverse osmosis membranes, in particular to an ultrasonically cleaned reverse osmosis membrane. Background technique [0002] At present, the reverse osmosis membrane water treatment process is recognized as one of the most effective desalination technologies. In the water treatment of thermal power plants, reverse osmosis devices have been widely used in raw water purification and desalination due to their simple operation, strong reliability, and no secondary pollution. However, during operation, the reverse osmosis membrane is inevitably polluted or blocked by some trace inorganic foulants, colloids, microorganisms, metal oxides, etc. These substances are deposited on the membrane surface and will accumulate more and more, resulting in a decrease in the permeation of the reverse osmosis membrane and a decrease in the salt rejection rate. Timely chemical cleaning of the reverse osmosis membrane can effectively ...

AI Technical Summary

Problems solved by technology

Since the customer base is basically large-scale equipment such as power generation units in thermal power plants, pure water systems in pharmaceutical factories, etc., this cleaning method is time-consuming and causes huge economic losses, and is laborious.
