Description

Membrane clamping device for cleaning filtering membrane

Technical Field

The utility model relates to the technical field of filtering membrane cleaning, in particular to a membrane clamping device for cleaning a filtering membrane.

Background

The sewage treatment is a process for purifying sewage to meet the water quality requirement of being discharged into a certain water body or reused. The sewage treatment is widely applied to various fields of buildings, agriculture, traffic, energy sources, petrifaction, environmental protection, urban landscapes, medical treatment, catering and the like, and the sewage treatment is increasingly carried into the daily life of common people.

In the sewage treatment process, the filtering membrane is generally used for filtering and purifying sewage, impurities can be accumulated on the surface of the side wall of the filtering membrane in the long-time use process of the filtering membrane, and a large amount of impurities can block the surface of the filtering membrane for a long time, so that the filtering effect of the sewage entering the filtering membrane is reduced.

The cleaning method of the filtering membrane mainly comprises two main types of physical methods and chemical methods. The cleaning method should be selected according to the configuration of the components, the membrane material, the type of the pollutant and the degree of the pollutant. The physical cleaning method is to peel off the pollutant on the surface of the film by using mechanical force, and does not generate any chemical reaction in the cleaning process. The specific method mainly comprises hydraulic flushing, air-water mixed flushing, countercurrent cleaning, hot water flushing and the like. The hydraulic cleaning is to utilize the high flow rate membrane surface formed after the pressure reduction of the membrane concentrate water side to accumulate soft impurities. The air-water mixed cleaning is to simultaneously introduce compressed air and water flow on the concentrated water side of the membrane, and clean impurities on the surface of the membrane by virtue of shearing action of air, water and the membrane surface. Countercurrent washing is primarily used for washing hollow fiber membranes by applying a counter pressure to the support layer to induce a counter flow of membrane permeate to loosen and remove contaminants from the feed side surface of the membrane.

In-process water conservancy washing at the physical washing filtration membrane, if the dynamics is little to wash the effect not good, if the dynamics is big to wash the time, the filtration membrane takes place the displacement under the impact of water conservancy easily, is inconvenient for the washing staff to the washing operation of filtration membrane, consequently in the waterpower physical washing in-process, how to control filtration membrane stability makes filtration membrane keep fastening, the washing of the in-process to filtration membrane of being convenient for water conservancy washing is the problem that prior art needs to solve.
