Abstract
The invention discloses a separator and a water purification method. The separator of the invention comprises a baffle, a filter element, a water supply device and a vacuum water suction device, wherein the filter element is positioned in the sealed baffle; an annular space is reserved between the baffle and filter cloth of the filter element; the water supply device is connected with the baffle; and the vacuum water suction device is connected with the filter element. The water purification method of the invention comprises the following steps that: liquid to be filtered moves around the filter cloth of the filter element in the sealed baffle and presses the filter cloth; clear solution penetrates the filter cloth to enter the filter element; and at the same time, the clear solution in the filter element is sucked under vacuum to keep a certain vacuum degree in the filter element. In the method, a positive and negative theory is adopted to perform filtering separation; impurities with weight exceeding a certain value quickly flows with the liquid to be filtered and are discharged out of the separator and part of the impurities can gradually settle into a circulatory pool; and light and fine suspended substances can form a relatively stable filterable membrane on the surface of the filter element to achieve the micro-filtration and ultra-filtration effects of membrane filtration.
Description
Technical field
The present invention relates to a kind of separator and a kind of method for purifying water, particularly a kind of mechanical type separator and use the method for purifying water of this separator.
Background technology
Along with the continuous revolution of industry and improving constantly of living standard, implementation of sustainable development, humane ecological environment requires more and more higher, so conserve water resource, sanitary water, reducing the water pollution is primary strategic issue in the present age, therefore can solve trade effluent, domestic water, and useful, effective filtration problem of industrial production link water is eternal research theme.The filter that exists mainly contains membrane separation device, vacuum-type drum filter, band filter and flame filter press at present.
Membrane separation device is to be separating medium with the film, and when having motive force in certain (as: pressure differential, concentration difference, potential difference etc.) in the film both sides, the material liquid component optionally sees through film, with the purpose that reaches separation, purifies.
The liquid film separation process mainly is meant micro-filtration, ultrafiltration, nanofiltration and reverse osmosis process.These pressure promote purification, extraction, the separation and concentrated that the film separation process can be used for solution.From micro-filtration, ultrafiltration, nanofiltration and counter-infiltration, the separated molecule or the size of particle are more and more littler, so membrane aperture must be more and more littler, and this resistance to mass tranfer that also means film increases, so operating pressure also is to increase gradually, to obtain similar flux.
Sum up membrane separation technique and be universally acknowledged high in technological content, be widely used, the new separation technology subject of development prospect light, the liquid film separation process is that other isolation technics can not replace, but should see that also membrane separation technique is not omnipotent, its application is restricted always, the difficult problem that isolation technics will be captured is that 1 investment is big, 2 maintenance difficulty are big, and 3 change membrane module cycle weak point, 4 energy consumption height, 5 concentrates can't be handled, the manufacture difficulty of 6 membrane modules is big, most dependence on import, and 7 pairs of filtered fluids require high.Such as aspect the trade effluent processing, the treatment technology that generally adopts, or biochemical process treatment technology now is even membrane technology is used the effect of also just adding a crucial touch to some extent.Aspect the industrial process waters preliminary treatment, handle the main at present exchange resin method of using as demineralized water, neither membrane processing method aspect the processing of people's domestic water, the isolated water quality of facial mask technology can reach pure water technology full maturity, but, why can not be in above-mentioned three big field extensive uses, has only a simple significantly reason " cost height " and a countless person of noble aspirations drops into a large amount of financial resources and material resources aspect the application of membrane separation technology trade effluent, though make progress, but, also do not have ripe general-purpose industrial sewage physics mechanical treatment process (film is main method) technical scheme to handle trade effluent.
Vacuum-type drum filter is the special equipment of industry such as starch, mainly contains two kinds: a kind of is to reclaim solid matter equipment, and as reclaiming material such as starch, the Separation of Solid and Liquid difficulty is big; Second kind is precoater, make precoating paint by materials such as diatomite, perlites, just can obtain qualified filtered fluid, has increased the filtration cost so greatly.From filtering cost and the filtrate difficulty being required, it is real that its application is restricted.
Band filter and flame filter press mainly are the solid effects of removing of industry such as trade effluent, and it mainly acts on is the solid content that reduces in the filtered fluid, and filtered fluid is of poor quality, can not reuse, can only handle discharging again by products for further.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of mechanical separator that reaches membrane separating effect is provided, and a kind of method for purifying water that adopts aforementioned separator to obtain membrane separating effect is provided.
In order to solve the problems of the technologies described above:
