Description
Technical Field
The utility model relates to the field of tubular membrane cleaning, in particular to a novel integrated tubular membrane pellet cleaning device.
Background
The tubular membrane technology is a new technology which is developed relatively well in recent years, and the traditional wastewater treatment technology generally comprises the steps of firstly using chemical dosing to enable ions to be removed to generate sedimentation, then using a sedimentation tank for solid-liquid separation, using a multi-medium filter for prefiltering the supernatant of the sedimentation tank, then adding hollow fibers for further turbidity removal treatment, and finally entering a subsequent recovery system. The whole treatment process flow is long, the investment is large, the treatment effect is unstable, the occupied area is large, and the operation cost is high. These drawbacks limit the development of the zero wastewater discharge market. However, the tubular membrane made of polypropylene has the advantages of high strength and acid and alkali resistance, and the integrated membrane structure can avoid weakening the filtering effect due to long-term friction, so that the tubular membrane can replace a traditional sedimentation tank and is increasingly used. However, after a period of use, fouling or contamination of the tubular membrane system is unavoidable, and the membrane system must be cleaned and regenerated.
The common cleaning modes of the tubular membrane are chemical cleaning and physical cleaning, and the chemical cleaning is carried out by selecting proper chemical agents for dissolution, oxidation or other chemical reactions according to the type of pollutants on the surface of the membrane so as to achieve the aim of removal; however, only the pollutants which can be subjected to soluble reaction with the cleaning liquid can be solved; the physical cleaning is usually hydraulic flushing, including forward flushing and back flushing, which can only solve membrane pollutants with low adhesion, and has poor effect on insoluble particles with high adhesion. Therefore, it is necessary to develop a new and efficient tubular membrane cleaning mode and tubular membrane industry.
Tubular membranes in some particular industries or application areas, for those particles that have strong adhesion and are insoluble, such as: silicon, organic colloid, charged organic matter, complex metal and the like, chemical cleaning agents and forward and backward flushing are difficult to recover the service performance of the film, the film is finally damaged, a tubular film is a core component in a sleeve type film treatment system, the film is finally replaced due to incorrect or improper cleaning mode, the running cost is increased, the traditional forward and backward flushing and chemical cleaning processes are low in efficiency, the cleaning time is long, and the agent use cost is high.
