Abstract
The present invention relates to a membrane filter which comprises a sewage pipe, a vacuum pipe, a water outlet pipe, an exhaust pipe, a baffle plate and a filter membrane. The present invention is characterized in that the filter membrane is a ceramic membrane, and forms a pipe shape, and both ends of the filter membrane are openings; one end of the filter membrane is an opening, and the other end is enclosed. When penetrating through the filter membrane under the action of pressure, sewage is filtered to be purified. The filter membrane has the advantages of wide source of raw materials, simple manufacture technology, low manufacturing cost and each popularization.
Description
The present invention relates to a kind of membrane filter, especially with the membrane filter of ceramic film pipe as filter membrane.
Water treatment practice is in recent years told us: the water technology of 21st century will can be affirmed based on membrane filtration, various membrane filters will occur in the society.Mainly use macromolecular material such as cellulose acetate, aromatic polyamides, thin-film composite membrane (polysulfones) in the present membrane filter, ceramic material such as micropore ceramic tube (plate, brick) are as filter membrane.Polymer material film desalination rate height can be made the doughnut formula, and water flux is big, but cost is high especially, and it mostly is external film imported, technology of preparing complexity, poor chemical stability, non-refractory.Micropore ceramic tube (plate, brick) is mainly used to handle the waste water that contains graininess, as the Separation of Solid and Liquid of power plant towards grey flushing cinder water, earthenware aperture, this microcosmic hole is bigger than normal, can not isolated by filtration come out for the material of some big molecules and HMW, and its scope of application is restricted.
The purpose of this invention is to provide a kind of membrane filter, be with the ceramic film be the pipe of material as filter membrane, it can remove the material of suspension and some big molecules and HMW effectively.
The object of the present invention is achieved like this: membrane filter of the present invention, comprise sewage water inlet pipe (1), crust of the device (2), vacuum tube (7), outlet pipe (5), blast pipe (8), baffle plate (6), filter membrane (3), it is characterized in that in the middle of the top of crust of the device (2), being provided with vacuum tube (7), tip edge at crust of the device is provided with blast pipe (8), top in a side of installing is sewage water inlet pipe (1), the bottom is outlet pipe (5), baffle plate (6) is arranged in crust of the device (2), filter membrane in crust of the device (2) is divided into two parts up and down with crust of the device (2), below in baffle plate (6), by baffle plate (6), the space that filter membrane (3) and crust of the device (2) are formed is full of quartz sand, and the material of filter membrane (3) is the ceramic film, filter membrane be shaped as tubulose, its both ends open, an or end opening, the sealing of one end, wherein the ceramic film is to be primary raw material by potter's clay or clay, percentage by weight is 80-90%, add small amount of activated, slag, shell, flyash, gypsum or wood chip, percentage by weight is 10-20%, make sun-dried mud brick, fired forming.The inlet of sewage water inlet pipe formula sewage, baffle effect are that sewage is isolated, and make sewage pass through filter membrane, and outlet pipe is the outlet of filtering water afterwards, and vacuum tube is to vacuumize, and water is oppositely flowed into from outlet pipe, so that the cleaning and filtering film.The ceramic film is that selection is a primary raw material with potter's clay or clay, percentage by weight is 80-90%, add small amount of activated, slag, shell, flyash, gypsum or wood chip auxiliary material (also claiming additive), percentage by weight is that 10-20% makes, wherein these auxiliary material can improve ceramic film pipe lithofacies structure, can be organically, also can be inorganic, also can be some waste materials.After potter's clay or clay add additive, add water again and stir, mold is made the tubulose sun-dried mud brick, but both ends open, also can an end opening, other end sealing.After the cool solarization of sun-dried mud brick pipe parches, sintering in furnace.In the sintering process, at first be the dehydration of potter's clay or clay mineral, when being heated 450～600 ℃, the kaolin dehydration in the mineral is decomposed, and produces steam, and follows volume contraction, and the carbon in the additive also can oxidized generation CO simultaneously
2Gas, these gases cause a lot of mutually the same very little air pockets in sun-dried mud brick, when sun-dried mud brick is converted into the ceramic film, in the ceramic film, just form network-like sinuate passage, these passages under artificial control, can accomplish diameter very little (＜100nm), when sewage during under pressure by ceramic membrane filtration film, this filter membrane can be with the polluter in the water, material as particulate matter and some macromolecules is retained down, and reaches the purpose of purification.
The present invention is owing to be that the pipe made with the ceramic film is as filter membrane, so the raw material sources of this filter membrane are wide, can gather materials on the spot, manufacture craft is simple, cost is low, make the price of the tubular filter film that this ceramic film makes low especially, also just make the cost that adopts this membrane filter to dispose of sewage low especially, applied easily.This ceramic membrane filtration film can be by kind, quantity, firing temperature and the cooling procedure of change additive and the thickness of film, the filter membrane of making multiple difference in functionality, different characteristics filters sewage of different nature, makes the scope of application of this membrane filter wider.
Apparatus structure of the present invention is provided by accompanying drawing 1.
Fig. 1 is the profile of the membrane filter of proposition according to the present invention.
