Description
Technical field
The invention belongs to field of water treatment equipment, relate to a kind of curtain immersion water process supermicro filtration membrane assembly.
Background technology
Water is Source of life, and being one of element indispensable in economic development, industrial and agricultural production, is also the material base that the mankind exist.In decades, along with the reform and opening-up of China, industrializedly to develop rapidly, the industrial wastewater of various complicated component and sanitary sewage are often below standard just directly enters water body, cause drinking water source water quality sharply to decline, traditional drink water purifying technology is faced with many challenges.In addition, China is the country of a serious water shortage, and water resource occupation rate is only 1/4 of world average level per capita, and the water consumption of ten thousand yuan of GDP is far away higher than international most advanced level, and current shortage of water resources has had a strong impact on the economic growth and social progress of China.Therefore, development of new high-effect drinking-water purification techniques and water depth treatment technology have great importance for guarantee drinking water safety, raising ratio of water recycle, reduction water consumption, promotion society and sustainable economic development.
Membrane technology became the hot issue of the research and apply of drink water purifying and useless (dirt) water depth process field in the last few years gradually.Ultrafiltration or micro-filtration can remove the predecessor of natural organic matter in water body and chlorine disinfection by-product most effectively, to the clearance of turbidity and bacterium close to 100%.
Immersion continuous membrane filter (SMF) can except the particle being greater than 0.03 micron in anhydrating.SMF utilizes external compression type hollow fiber ultrafiltration membrane, by low pressure air water two to wash+operation such as backwash and backwash process maintain the operating flux of system.The flow direction of filtering is the inner chamber from the outer wall of doughnut to hollow.Solid in water is trapped in outer wall by the fibre wall of porous by water inlet.Film can remove the particle being greater than 0.03 micron, the materials such as the microorganism effectively in removal water and suspension.The critical piece of SMF unit is SMF membrane component.SMF membrane component to take out, and carry out the filter element repairing or change.SMF membrane component is made up of thousands of microporous hollow fiber film silk and end socket.Membrane module upper end end socket can allow filtrate to flow to from hollow-fibre membrane inner chamber the pipeline that catchments.The outlet of bottom bulkhead shutoff tunica fibrosa, but allow low pressure process air when backwash from end socket a series of perforate through the outer surface entering membrane fiber.
The backwash of existing curtain ultrafiltration apparatus adopts bubble to rinse, venthole is generally all distributed in the edge of a branch of film wire tray, or at the edge of a row film tow, flushing can only be flushed to edge or the film silk nearer apart from edge, the film silk far away to middle part distance pore does not flush, whole bundle film silk well can not be rinsed, affect filter efficiency.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, the curtain immersion water process ultra micro membrane module that a kind of apparatus structure is simple, cleaning performance good, filter efficiency is high is provided.
The process program that the present invention realizes object is as follows:
A kind of curtain immersion water process supermicro filtration membrane assembly, comprise film silk, air inlet pipe, upper film wire tray, lower film wire tray, water leg and inflatable chamber, the sealing of upper film wire tray upper end is installed and is connected water leg, water leg is communicated with drainage by suction pipe, inflatable chamber is installed in the sealing of lower film wire tray lower end, inflatable chamber connects air inlet pipe, the two ends of film silk and air inlet pipe cast in film wire tray and lower film wire tray respectively uniformly at intervals, film silk and air inlet pipe form staggered mode of evenly arranging, it is outlet end that film silk is positioned at film wire tray end, be communicated with water leg, the end being positioned at lower film wire tray is sealed end, the end that air inlet pipe is positioned at film wire tray is sealed end, being positioned at lower film wire tray end is inlet end, be communicated with inflatable chamber, be shaped with venthole being positioned at the air inlet pipe sidewall that lower film wire tray top is about 0-20cm position.
The advantage that the present invention obtains and beneficial effect are:
The curtain immersion water process supermicro filtration membrane assembly that the application provides all arranges an air inlet pipe between every two adjacent film silks, like this when rinsing film silk, each surface of every root film silk all can obtain the flushing of bubble, greatly improves developing result.
The venthole of the escape pipe of the curtain immersion water process supermicro filtration membrane assembly that the application provides is arranged on the root near film wire tray, the bubble that pore bloats can wash away from film silk root, certain radial impact effect can also be produced to film silk while bubble upwards floats, film silk surface is made to produce microseism, in the whole process that bubble rises, the whole surface of film silk can both be washed and microseism, improves the developing result of each section of film silk.
The curtain immersion water process supermicro filtration membrane assembly that the application provides is in preparation overshoot, propose novel film silk and the distribution mode of tracheae, the end of film silk and tracheae is made to produce upper and lower difference in height, the difference ventilation of film silk and tracheae can be reached and lead to liquid effect after crosscut, so just solve the problem that pore is arranged, reach good effect.
