Abstract
The invention relates to coating water purification technology, and in particular relates to a reverse osmosis membrane applicable to coating water purification. According to the invention, the technical scheme is as follows: the reverse osmosis membrane applicable to coating water purification comprises a central pipeline, a membrane element, a left end cover and a right end cover, wherein the membrane element is formed by winding the reverse osmosis membrane around the central pipeline; the left end cover and the right end cover are respectively connected with two ends of the membrane element hermetically; and a circular raw water inlet is formed on the right end cover. The reverse osmosis membrane can effectively balance the pressure in the membrane element, so that the membrane element is not easily damaged due to overlarge pressure and also has good purification effect.
Description
Technical field
The present invention relates to the application water treatment technology, particularly a kind of reverse osmosis membrane that is applicable to that application water purifies.
Background technology
Reverse osmosis membrane of the prior art; Like Granted publication number is the disclosed integrated reverse osmosis film of utility model patent of CN201470326U; This integrated permeable membrane comprises the membrane component of film end cap and tubular; In membrane component, be provided with spiral and roll the ultralow pressure counter-infiltration diaphragm that forms, two ends and both that the film end cap is connected in membrane component are solidly fixed, and on the film end cap, are provided with water outlet interface, water inlet interface and dense water interface; Yet because the water inlet interface of this reverse osmosis membrane generally all deviates from film end cap center, thus cause the membrane component internal pressure inconsistent easily, thus influence clean-up effect, simultaneously, because the subregion hypertonia is also damaged membrane component easily.
Summary of the invention
The purpose of this invention is to provide a kind of reverse osmosis membrane that is applicable to that application water purifies, the pressure in its ability active balance membrane component, thus make membrane component be difficult for damaging owing to pressure is excessive, also have good clean-up effect simultaneously.
Above-mentioned technical purpose of the present invention is achieved through following technical scheme: a kind of reverse osmosis membrane that is applicable to that application water purifies; Comprise center culvert, roll the membrane component that forms, the left end cap and the right end cap that are connected with the membrane component sealed at both ends respectively by the counter-infiltration diaphragm around center culvert, said right end cap is provided with annular former water inlet.
As of the present invention preferred, the axis of the former water inlet of said annular overlaps with the axis of center culvert.
As of the present invention preferred, said left end cap is provided with dense water concentration chamber, and dense water concentration chamber is provided with dense water out.
As of the present invention preferred, the thickness of said dense water concentration chamber is 1-3cm.
As of the present invention preferred, said right end cap is provided with the treated water outlet that communicates with center culvert.
As of the present invention preferred, the axis of said treated water outlet overlaps with the axis of annular former water inlet.
In sum, the present invention has following beneficial effect: the present invention has good clean-up effect; The setting of the former water inlet of annular makes former water feed membrane component as far as possible equably, thereby makes the pressure in the membrane component consistent as far as possible, so that the counter-infiltration diaphragm is difficult for damaging; The axis of the former water inlet of shape and the setting that the axis of center culvert overlaps are the isostasy degree that further improves in the membrane component; The setting of dense water concentration chamber also further helps improving the membrane component internal pressure balanced intensity near the left end cap place; Dense water concentration chamber is too thin then to be unfavorable for drawing dense water, too thickly then can cause near the membrane component internal pressure at left end cap place too for a short time, and therefore, through constantly practice, the thickness of preferred dense water concentration chamber is 1-3cm.
