Abstract
The utility model discloses a vertical roll type membrane filtering device which comprises a vertical membrane housing, and is characterized in that a roll type membrane component adapting to the membrane housing is arranged in the membrane housing; an upper sealing head and a lower sealing head are arranged at the upper end and the lower end of the membrane housing respectively; a permeating liquid output pipe is arranged in the roll type membrane component; an upper permeating liquid outlet and a lower permeating liquid outlet passing through the upper sealing head and the lower sealing head respectively and extending outwards are formed at the two ends of the permeating filtrate output pipe; and an upper water flow opening and a lower water flow opening are formed at two ends of the membrane housing respectively. By adopting the structure, the vertical roll type membrane filtering device has the advantages that the membrane housing and the roll type membrane component are placed vertically and the membrane surface can be effectively cleaned by means of tiny bubbles formed by gas and water, so that the recovery ratio of high-value materials is increased, the service life of the membrane is prolonged, the cleaning time is reduced, the operating cost of a membrane device is reduced, and a membrane system is widely used for separating materials and recycling recycled water.
Description
Technical field
The utility model relates to a kind of rolled film filter, belongs to a kind of separation technology field or water supply and drainage, environmental technology field.
Background technology
Membrane separation technique is meant under the motive force effect, utilizes the selection permeability of film, makes the separated technology of each component in the mixture.Membrane separation technique is widely used in fields such as water supply and drainage, food and drink, pharmacy, chemical industry.Vigorously advocate in the trend of also carry out earnestly energy-saving and emission-reduction, recycling economy in mankind nowadays society, membrane technology will be appeared suddenly more in the application aspect feed separation and the middle water reuse.
Film separates can be divided into micro-filtration, ultrafiltration, nanofiltration and counter-infiltration by the incision of matter size.Shape by film, membrane module roughly is divided into hollow-fibre membrane, tubular membrane, board-like film and rolled film.The membrane area that rolled film fills with its unit volume is big, flow passage design, the operation power cost is low and the application quantity maximum, and application is the widest.
In the prior art, rolled membrane module fills 1 ~ 7 membrane component by pressure vessel and single pressure vessel and forms, the transversely arranged combination of membrane module is often formed a cover membrane separation device by pretreatment system, pressure charging system, pipeline, instrument, electrical control, support etc.
Influence film separation system operation most critical factor and be and suppress that film pollutes and how film more effectively cleans after polluting, particularly film separates and is applied to feed separation, purification, concentrates and larger middle water reuse.Effective air water cleaning method cheaply, because of horizontal membrane module can not be used, assembly in service (pressure vessel) though in enter a small amount of gas, will cause gas to be concentrated on membrane component top, cause the damage of membrane component.On the one hand, when film was applied to feed separation, because separated material is common than the simple relatively easier polluted membrane of water treatment, film needed the higher cleaning agent that cleaning frequency, composition are more, price is higher, more scavenging period.It is big to it is worth noting that more separated material is worth; material in the horizontal membrane module has to come out with other liquid displacement before cleaning or interim the shutdown; cause separated object yield low, cause device operating cost height, membrane lifetime weak point like this, influenced the application that film separates.On the other hand, film separate be applied in during the water reuse, because middle water is various waste water reach discharge standard substantially after suitable PROCESS FOR TREATMENT water, compare simple with film separation of produced pure water, water purification, desalinization etc., water inlet composition complexity, the factor of polluted membrane is many, and film also needs more effective preliminary treatment, higher cleaning frequency, more scavenging period.More can not effectively discharge because of the water in the horizontal membrane module, purging system needs the water dilution in the higher Chemical cleaning agent concentration tunicle.Film has influenced the application of water reuse during film is separated in equally because of cleaning frequency height, cleaning are thorough, the life-span is short.
The utility model content
The utility model provide a kind of easy cleaning, few with chemical agent clean, cleaning charge is low, effective, the rolled film filter of film long service life.
In order to solve the problems of the technologies described above, a kind of erect-type rolled film filter of the present utility model, comprise and erect the film shell of placing, the rolled film element that adapts to it is installed in the described film shell, described film shell upper and lower end is separately installed with upper and lower seal head, have through the liquid efferent duct in the described rolled film element, should see through the filtrate output tube two ends and be provided with and pass upper and lower seal head respectively and extend in the outer upper and lower liquid outlet that sees through, film shell two ends also are respectively arranged with upper and lower current opening.
Be respectively arranged with upper and lower thrust ring between described rolled film element and the upper and lower seal head.
The described current opening of going up is arranged on the seal head, and described current opening down is arranged at film shell following side.
Described rolled film element is a kind of in coiled reverse osmosis membrane element, rolling NF membrane element, rolling ultrafiltration membrane elements and the rolling micro-filtration membrane element.
The beneficial effects of the utility model are: this erect-type rolled film filter is owing to adopt said structure, and film shell and rolled film element are erect and placed, and can carry out more effective cleaning to the film surface by means of the micro-bubble of gas and water formation.Help to improve the rate of recovery of high value material, prolong film service life, reduce that scavenging period becomes and the operating cost that reduced film device makes the film system more extensive in the application of feed separation and middle water reuse.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1, a kind of erect-type rolled film filter of the present utility model, comprise and erect the film shell of placing 1, the rolled film element 2 that adapts to it is installed in the described film shell 1, described film shell 1 upper and lower end is separately installed with upper and lower seal head 3,4, have through liquid efferent duct 5 in the described rolled film element 2, should see through filtrate output tube 5 two ends and be provided with and pass upper and lower seal head 3,4 respectively and extend in the outer upper and lower liquid outlet 6,7 that sees through, film shell 1 two ends also are respectively arranged with upper and lower current opening 8,9.When filtering, former water enters film shell 1 from following current opening 9, after cutting one group of membrane component, part flows out from last current opening 8, since the effect of hydraulic pressure, former water section see through reenter in the film bag that film enters membrane component 2 through liquid efferent duct 5 for see through liquid, seeing through liquid can be from seeing through liquid outlet 6 or seeing through liquid outlet 7 outputs down.This erect-type rolled film filter is owing to adopt said structure, and film shell 1 and rolled film element 2 are erect and placed, and can carry out more effective cleaning to the film surface by means of little water vapor bubbles of gas and water formation.Help to improve the high value material the rate of recovery, prolong film service life, reduce that scavenging period becomes and the operating cost that reduced film device makes the film system more extensive in the application of feed separation and middle water reuse.
