Description

Technical Field

[0001] The present invention relates to the technical field of water purification equipment, and in particular to an intelligent modular ultrafiltration membrane water purification device and a use method thereof. Background Art

[0002] Water is the source of life. It plays an important role in our lives. It is one of the most important and indispensable material resources for human survival and development.

[0003] With the development of modern industry, water pollution has become the focus of human attention. People are more and more concerned about the various water factor parameters of the drinking water they drink. As far as families are concerned, people have different requirements for water quality in different occasions.

[0004] At present, drinking water purification equipment is becoming more and more common, and the main unit of water purification equipment filtration is the filter element. The quality of the filter element directly affects the overall performance of the water purification equipment. After the water purification equipment has been running for a long time, it is very easy for impurities to adhere to the surface of the filter element membrane, causing blockage of the filter element membrane pores, resulting in a decrease in water production flux, and even causing the components to be unusable in severe cases, affecting the service life. Therefore, it is necessary to clean the filter element membrane, but the cleaning is difficult, and generally requires professional personnel to come to the door for cleaning and replacement, and the cost of changing the core is generally high. At present, the common method in the industry to improve the life of the filter element is to use a water flow flushing method, that is, to flush the impurities on the surface of the filter element membrane with water flow, such as patent number CN202023125378.4 discloses a water purification device, including a support frame, a mounting groove is provided on the support frame, a flushing tank is provided in the mounting groove, one side of the flushing tank is connected to a supercharger structure, and the other side of the flushing tank is provided with a filter element assembly, so that the flushing tank flushes the filter element assembly. A water purifier is also disclosed, including a filter element assembly, and the filter element assembly is connected to the water purification device as described above. The utility model provides a water purifier, which can perform individual or cyclic flushing through a flushing water channel provided in the water purifier, perform high-pressure flushing on the filter element assembly, increase the flushing time and flushing water volume, improve the flushing effect, and increase the service life of the filter element. However, the water purifier has the following problems: 1. It is unable to detect water quality, and cannot flush the filter element according to water quality information; 2. Flushing the filter element produces waste water, which not only wastes water resources, but also makes the water non-recyclable; 3. Only using a flushing tank and a boosting structure to flush the filter element cannot completely wash away the dirt in the membrane pores of the filter element.

[0005] As well as the water purification system and flushing control method and device disclosed in Patent No. CN202310033563.X, the ultrafiltration membrane filter element is flushed by circulating the stored water in the water purification system in the clean water passage and the wastewater passage, but there is cross contamination, which can easily cause the RO membrane filter element and the composite filter element to be contaminated again.
