Description

Technical Field

[0001] The utility model relates to the technical field of membrane separation, in particular to a membrane separation equipment cleaning device. Background Art

[0002] Membrane separation technology refers to the technology of selectively separating a mixture of molecules of different particle sizes at the molecular level when passing through a semipermeable membrane. There are three main methods for deep treatment of printing and dyeing wastewater: chemical method, physical method, and biological method. Membrane separation is a kind of physical method. The advantage of using the membrane separation method is that high reliability of water treatment can be obtained, because the required water purity can be easily and stably met by adjusting the size of the membrane pores. However, when a filter membrane assembly is used to filter a fluid suspended with pollutants including solid components, the filter membrane is easily contaminated by the pollutants, resulting in a decrease in the water permeability of the filter membrane. Therefore, it is necessary to regularly remove pollutants from it to clean the filter membrane.

[0003] The existing method for cleaning the filter membrane is to remove the filter membranes and then clean them one by one, which is cumbersome to operate and has low cleaning efficiency.

Although the combination of the membrane separation device and the membrane cleaning machine comprises a membrane separation device body and membrane elements, a plurality of membrane elements are arranged in the membrane separation device body, a pushing and scraping mechanism is arranged directly above the membrane separation device body, and the pushing and scraping mechanism is connected to the driving mechanism; in the utility model, a cleaning mechanism is directly added to the membrane separation device. Through the combination of the two, the production and procurement costs of the equipment can be reduced, and at the same time, the area occupied by the equipment can be reduced, so that the space of the working area is more reasonably and fully utilized, thereby having a higher practical value.

[0005] Although the above patent has achieved the goal of reducing the production and procurement costs of the equipment by directly adding a cleaning mechanism in the membrane separation equipment, and at the same time, reducing the area occupied by the equipment, making the space of the working area more reasonably and fully utilized, thus having a higher practical value; however, the cleaning effect of the device is not obvious, there are cleaning dead corners, and the bottom of the membrane element is not easy to be cleaned, which may affect the filtering effect of the membrane element.

[0006] Therefore, it is necessary to invent a membrane separation equipment cleaning device to solve the above problems. Utility Model Content
