Description
Technical Field

Ultrafiltration is a pressurized membrane separation technology, namely, under a certain pressure, small molecular solutes and solvents (such as water molecules, inorganic salts, small molecular organic matters) and the like penetrate a specially-made ultrafiltration membrane with a certain aperture, and macromolecular solutes such as suspended matters, colloid, proteins, microorganisms and the like cannot penetrate and remain on one side of the ultrafiltration membrane, so that the aim of purification or separation is achieved. The ultrafiltration filter adopting the principle of ultrafiltration technology can be widely applied to wastewater and sewage purification treatment.
After the ultrafiltration filter operates for a period of time, suspended matters such as sediment and other macromolecular substances are attached to the ultrafiltration membrane and the periphery of the ultrafiltration membrane, and periodic cleaning and maintenance are required, otherwise, the continuous use and the purification effect are affected. The most common cleaning method is to use clean water or add chemical agents to perform forward flushing, that is, the water is flushed along the water flow direction of the ultrafiltration filter when the ultrafiltration filter is originally operated. However, in long-term production practice, it has been found that some impurities and pollutants may adhere to and clog the ultrafiltration membrane due to the small gap between the filtration membranes, so that the forward flushing is not easy to flush the impurities and pollutants into the filtration membranes. In addition, it has been found that impurities or contaminants, particularly suspended matter such as silt, are most likely to collect at the water outlet end of the ultrafiltration filter, i.e., the end from which produced water and concentrate flow. A large amount of impurities or pollutants are concentrated at one position, are more easily attached to the surface of the filtering membrane and are not easy to rinse, and the cleaning effect cannot be achieved according to a conventional rinsing mode.

The housing 10 is cylindrical, and a cavity 101 is formed in the housing 10. In other embodiments, the housing 10 may be provided in other shapes, such as a rectangular parallelepiped shape.
The ultrafiltration membrane cartridge 20 is disposed in the cavity 101 of the housing 10. The ultrafiltration membrane filter element 20 is a tubular ultrafiltration membrane, and two ends of the ultrafiltration membrane filter element are provided with openings. The number of the ultrafiltration membrane filter cores 20 can be reasonably set into a plurality according to the requirement, and all the ultrafiltration membrane filter cores 20 are distributed in the cavity 101 of the shell 10 at intervals in parallel.

As shown in fig. 2, the aeration flushing type ultrafiltration filter according to the second embodiment of the present invention is basically identical to the first embodiment in structure, and similarly includes a housing 10A, an ultrafiltration membrane cartridge 20A, except that an aeration member 50A is provided at the center of the first sealing head 30A. The first sealing head 30A is hemispherical, an aeration port 302A is formed in the center of the first sealing head 30A, and a water inlet 301A of the first sealing head 30A is positioned on one side of the aeration port 302A. Similarly, the aeration member 50A is an arc-shaped aeration plate provided inside the first sealing head 30A. The second sealing joint 40A is also hemispherical, the produced water outlet 401A is positioned at one side of the second sealing joint 40A, and the concentrated water outlet 402A is positioned at the center of the second sealing joint 40A.
As shown in fig. 3 and 4, the aeration rinsing type ultrafiltration filter according to the third embodiment of the present invention is basically identical to the first embodiment in structure and also includes a housing 10B, an ultrafiltration membrane cartridge 20B, a first sealing head 30B, and a second sealing head 40B, except for an aeration member 50B. The housing 10B has a cavity 101B therein, and a plurality of ultrafiltration membrane cores 20B are arranged in the cavity 101B in parallel and spaced apart. The first and second sealing joints 30B and 40B are respectively and correspondingly mounted at both ends of the housing 10B.

One end of each of the gratings 51B is collected in the center of the second sealing head 40B and is communicated with the aeration port 403. Optionally, the grille 51B is S-shaped, wavy or zigzag. The grid 51B shown in fig. 3 is S-shaped, and aeration holes 5101B are uniformly distributed in the grid 51B. When gas is introduced into the aeration openings 403B through the gas supply means, the gas enters the respective grids 51B through the aeration openings 403B and finally is sprayed toward the respective ultrafiltration membrane cartridges 20B through the respective aeration holes 5101B. It will be appreciated that by radially distributing the plurality of grids 51B on the inner wall of the second sealing head 40B centering around the aeration openings 403B, all of the grids 51B are distributed around the end portions of the ultrafiltration membrane cartridges 20B, and the respective aeration holes 5101B of the grids 51B face the respective ultrafiltration membrane cartridges 20B at different angles, so that gas can be uniformly flushed to all of the ultrafiltration membrane cartridges 20B.

According to the invention, by arranging the aeration members 50 (50A, 50B) on one of the first sealing joints 30 (30A, 30B) and the second sealing joints 40 (40A, 40B), the aeration members 50 (50A, 50B) jet gas to the ultrafiltration membrane filter cores 20 (20A, 20B) in the shell 10 (10A, 10B) to flush pollutants on the side walls of the ultrafiltration membrane filter cores 20 (20A, 20B), and the pollutants which are concentrated on the side walls of the ultrafiltration membrane filter cores 20 (20A, 20B) are more easily flushed by utilizing the impact force of high-speed airflow.
In practical applications, the side walls of the ultrafiltration membrane filter cores 20 (20A, 20B) can be flushed again by introducing produced water or clean water from the second sealing joints 40 (40A, 40B) in a backwashing mode after aeration flushing. Or the two modes of aeration scouring and water backwashing scouring can be simultaneously carried out. Therefore, the cleaning effect can be greatly improved by adopting a mode of combining gas scouring and water backwashing scouring.
It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are by way of example only and are not limiting.
