Description

A tubular membrane cleaning device

technical field

The invention relates to the field of membrane separation, in particular to a tubular membrane cleaning device.

Background technique

At present, with the application of tubular membranes in the field of high-concentration sewage treatment, such as landfill leachate treatment, special chemical wastewater (coking, tanning, textile, etc.) treatment, oilfield produced water reinjection, emulsified oil treatment, medium and low concentration sewage (Electronic wastewater treatment, municipal sewage, etc.); and the field of material separation, such as tea beverages, fruit juice clarification and concentration, food, biopharmaceutical fermentation liquid clarification, electrophoretic paint and other substance recovery. Users are paying more and more attention to the fouling and cleaning of the filter surface inside the tubular membrane, which is the key to the filtration and cleaning of the tubular membrane. When the tubular membrane is filtering, as time goes by, the fouling layer formed on the surface of the inner filter surface will continue to thicken, resulting in a continuous decrease in the dialysis filtration rate per unit area. Therefore, the inner filter surface of the tubular membrane needs to be cleaned regularly. In the prior art, the cleaning of the inner filter surface of the tubular membrane usually includes mechanical cleaning, such as backwashing, air washing, air-water washing, scrubbing with soft spherical particles, and chemical cleaning. At present, one or more combinations of backwashing, air-water washing and chemical washing are widely used in the market. However, backwashing requires a lot of backwashing water; air washing requires less backwashing water, but it consumes more gas; chemical cleaning, the effect is better, but it consumes chemical costs, and the membrane components need to be resistant to chemical corrosion .
