Novel offline reverse osmosis membrane cleaning equipment and cleaning process

Abstract

The invention relates to the field of reverse osmosis membrane cleaning, in particular to novel offline reverse osmosis membrane cleaning equipment and a cleaning process thereof. The technical problems that due to an online cleaning mode in the prior art, cleanout fluid is long in cleaning process in the process of cleaning a reverse osmosis system, effective ingredients of the cleanout fluid aregradually reduced in the cleaning process, the cleaning efficiency is reduced, and the cleaning effect is reduced; meanwhile, contaminants cleaned off from a front end reverse osmosis membrane assembly are mixed in the cleanout fluid, a rear end reverse osmosis membrane assembly is contained and blocked for the second time, the rear end reverse osmosis membrane assembly is more seriously contaminated originally than the front end reverse osmosis membrane assembly, and therefore the cleaning effect of the rear end reverse osmosis membrane assembly is greatly reduced are solved. In order to solve the technical problems, the novel offline reverse osmosis membrane cleaning equipment and the cleaning process thereof are disclosed, the novel offline reverse osmosis membrane cleaning equipment comprises a cleanout fluid supply part and a cleaning part, and the cleaning part is connected with the cleanout fluid supply part.

Description

technical field [0001] The application relates to the field of reverse osmosis membrane cleaning equipment, in particular to a novel offline reverse osmosis membrane cleaning equipment and a cleaning process thereof. Background technique [0002] The reverse osmosis membrane module is a valuable component of the reverse osmosis system. Proper use and effective maintenance make the reverse osmosis membrane module last for several years. After the reverse osmosis system runs for a certain period of time, a layer of pollutants will be deposited in the reverse osmosis membrane module, affecting The performance of the reverse osmosis system needs to be cleaned to restore the performance of the reverse osmosis system. [0003] At present, there are two main cleaning methods for reverse osmosis membrane modules: online cleaning and offline cleaning. When the online cleaning method is adopted, since the reverse osmosis membrane module in a large reverse osmosis system is generally ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved in this application is that the online cleaning method leads to a long cleaning process of the lotion in the process of cleaning the reverse osmosis system, and the effective components of the cleaning solution will gradually decrease during the cleaning process, resulting in a decrease in cleaning efficiency, resulting in a The effect is reduced; at the same time, the pollutants cleaned from the front-end reverse osmosis membrane components are mixed in the cleaning solution, causing secondary fouling to the rear-end reverse osmosis membrane components, and the rear-end reverse osmosis membrane components are already higher than the front-end reverse osmosis membrane components. The pollution is more serious, which further leads to a serious decline in the cleaning effect of the back-end reverse osmosis membrane components
