A kind of plan membrane filtration mandrel component

Technical field

The invention belongs to water filtration technology field, intend membrane filtration mandrel component particularly to a kind of.

Background technology

With the continuous improvement of industrial continuous revolution and living standard, the enforcement of the strategy of sustainable development, humane life State environmental requirement more and more higher, therefore saving water resource, sanitary water, reducing water pollution is contemporary Primary Strategies problem, Therefore, it is possible to solve trade effluent, domestic water, useful, effective filtration problem of industrial production link water is eternal Research theme.

The filter that presently, there are mainly has membrane separation device, vacuum-type drum filter, band filter, sheet frame Filter and medium filter etc..

Membrane separation device is with film as separating medium, there is certain motive force (such as: pressure differential, dense in film both sides Spend poor, potential difference etc.) when, the transmission film of material liquid compositional selecting, to reach the purpose separating, purifying.

Liquid membrane separating process is primarily referred to as micro-filtration, ultrafiltration, nanofiltration and reverse osmosis process.These pressure promote film to divide From process can be used for the purification of solution, catch take, separate and concentrate.From micro-filtration, ultrafiltration, nanofiltration and counter-infiltration, detached The size of molecule or particle is less and less, and therefore membrane aperture must be less and less, this also means that the resistance to mass tranfer of film increases, So operating pressure is also to be gradually increased, to obtain similar flux.

It is universally acknowledged high in technological content for summarizing membrane separation technique, is widely used, bright new point of development prospect From technology-oriented discipline, liquid membrane separating process is that other isolation technics can not replace, but it should also be recognized that membrane separation technique It is not omnipotent, its application is constantly subjected to limit, an isolation technics difficult problem to be captured is that 1 investment is big, 2 maintenance dimensions Shield difficulty is big, and 3 change membrane module cycle is short, 4 high energy consumptions, and 5 concentrates cannot be processed, and the manufacture difficulty of 6 membrane modules is big, most Dependence on import, 7 pairs of filtered fluids have high demands.Such as in terms of Industrial Waste Water Treatments, now commonly used treatment technology, Or biochemical process treatment technology, even if membrane technology has applied the effect also simply add a crucial touch.Pre- in industrial process waters Process aspect, such as softens water process and mainly applies exchange resin method at present, be not film in terms of people's domestic water process Facture, the water quality that membrane technology is isolated can reach pure water technology full maturity, but, why can not be above-mentioned Three big fields are extensively applied, only one of which simply substantially the reason " high cost " and a countless person of noble aspirations in membrane separation technique Applicable industry sewage aspect has put into substantial amounts of financial resources and material resources although making progress, but, also do not have ripe general Trade effluent physical mechanical facture (method based on film) technical scheme processes trade effluent.

Band filter be mainly the industry such as trade effluent except solid effect, its Main Function is to reduce in filtered fluid Solid content, filtered fluid of poor quality it is impossible to reuse, can only wait processing further and discharge again.

Flame filter press application is wider, and the filtered fluid quality of process can meet different technique productions needs, Output and sales volume are very big, but it exist shortcoming also indubitable it is impossible to realize clean manufacturing, equipment volume is big, work Journey is installed and floor space is huge, and cost of use is high, including consuming energy, high, filter cloth replacing cycle is short automation mechanized operation difficulty is high, Invest big etc..

Medium filter (representational is sand filter such as sand cylinder) be low cost, technology maturation, applied range, A kind of long filter removing oil removal of usage history.Its shortcoming is that filter efficiency is low, filtering accuracy is low, backwash consumption The water yield is big, number of times is high, leakiness sand, and the sand cylinder usage cycles of common compact are short, operation is difficult to control, power consumption is higher, no By being sand cylinder or sand pond is all sufficiently bulky, therefore project occupation of land area is big, project installation is complicated, construction costs is huge.

In sum, with the continuous development of industrial technology, whether membrane technology or medium filter etc., all cruelly Reveal its inapplicable shortcoming and improve it is necessary to improve, replacing it, this is the needs of development to the product of innovation to be had in other words.
