Description
Technical field
The present invention relates to a kind of water filtration rolled membrane module with binary channels center tube structure, belong to clean water treatment technical field.
Background technology
Due to high filter densities and simple molding mode efficiently, rolled film has become the main flow filter cartridge construction of water filtration especially high-accuracy water filtration reverse osmosis membrane.At present, known coiled reverse osmosis membrane element is by by pure water flow-guiding screen, counter-infiltration diaphragm, water purification diaphragm group that water inlet flow-guiding screen superposes formation is in a certain way wrapped in and center water producing pipe is formed, need in coiling process to fold counter-infiltration diaphragm, in the water inlet flow channel formed between the inner surface of described water inlet flow-guiding screen after counter-infiltration diaphragm folds, in the product water flow passage formed between the outer surface of described pure water flow-guiding screen after counter-infiltration diaphragm folds, this coiled reverse osmosis membrane element to produce the section dual-side of water flow passage and to make product water flow passage have opening towards center water producing pipe away from a side glue bonding of center water producing pipe, water purification diaphragm group is after the water producing pipe of winding center, the outer adhesive tape environmental sealing of outer surface.The coiled reverse osmosis membrane element of this structure is in running, former water is from the inflow water inlet flow channel of an end face of element, part water forms pure water through counter-infiltration membrane filtration and flows in the water producing pipe of center along pure water flow-guiding screen, and the remaining dense water not filtering formation flows out along the water inlet flow-guiding screen in water inlet flow channel from the other end of element.Because the water inlet direction of this reverse-osmosis membrane element is consistent with the direction that concentrated water drainage removes, thus cause runner wide, flow process is short, the speed of water inlet in runner is slower, therefore, film surface easily produces concentration polarization phenomenon, causes membrane component to pollute, salt rejection rate and aquifer yield are reduced, the membrane component lost of life.
In order to overcome above-mentioned defect, China Patent Publication No. is CN 101708433A, and publication date is 2010.05.19, discloses a kind of coiled reverse osmosis membrane element.This coiled reverse osmosis membrane element, by the partial sector closing seam of the dual-side adjacent with flanging of water inlet flow channel away from center water producing pipe, makes this dual-side form segment raw water inlet respectively near water producing pipe place, center and make the side relative with flanging of water inlet flow channel form dense water delivery port.Through such improvement, make into water consistent with water purification film winding direction with dense water direction, increase the water velocity on reverse-osmosis membrane element film surface, decrease film surface concentration polarization, reduce the pollution speed of wound membrane element, thus extend the service life of membrane component.But this coiled reverse osmosis membrane in use finds, because this reverse osmosis membrane is 90 degree of water intake modes, raw water inlet place has into water dead angle, and the time has grown easy fouling, affects effluent quality.
In order to overcome above-mentioned defect, China Patent Publication No. is CN101838033A, and publication date is 2010.09.22.Disclose a kind of coiled reverse osmosis membrane element.This coiled reverse osmosis membrane element is also be provided with water inlet pipe at the dual-side adjacent with flanging of water inlet flow channel close to water producing pipe place, center, forms segment raw water inlet; At the partial sector closing seam of this dual-side away from center water producing pipe, the side relative with flanging of water inlet flow channel is made to form dense water delivery port.This coiled reverse osmosis membrane element, except can increasing film surface water Flow Velocity, mainly solves and does not establish water inlet pipe and the water inlet Dead Core Problems of the raw water inlet caused, thus avoid raw water inlet fouling and improve water quality.But this reverse osmosis membrane, be equipped with water inlet pipe in each raw water inlet, water inlet pipe is separated with central tube, thus increases the difficulty that glue is played in sealing, and in actual production, operability is not strong, and production efficiency is low.
In sum, the structure of above coiled reverse osmosis membrane element constantly in change, but and the improvement of unresolved water distribution system and rolling technology simplify between contradiction.In addition, existing rolled film is mainly reverse osmosis membrane filter element, is not applied in fields such as micro-filtration, ultrafiltration, nanofiltrations, limits the performance of rolled film structural advantage, also make the membrane component form of different filtering accuracy single, hinder the development of membrane filtration technique and industry.
Summary of the invention
