Abstract
The utility model belongs to the technical field of reverse osmosis water purification, and relates to a reverse osmosis filter device. The reverse osmosis filter device comprises a film shell and a film element arranged in the film shell, wherein a first gap is formed between the circumferential surface of the film element and the inner wall of a shell body, a raw water inlet end face and a concentrated water outlet end face are respectively formed on two end faces of the film element, and a pure water outlet is formed at one end of a central tube in the film element. The film shell is provided with a raw water hole, a concentrated water hole, and a pure water hole communicated only with the pure water outlet. The reverse osmosis filter device is characterized in that the raw water hole and the concentrated water hole are both arranged at one end of the film shell near the concentrated water outlet end face, and are separated with each other. The raw water hole is communicated with the raw water inlet end face through the first gap. The reverse osmosis filter device has the advantages that recycling dead angles do not exist in the film shell when the reverse osmosis filter device filters water, water in the film element and the film shell is almost completely replaced when the reverse osmosis filter device is washed, concentration of water in the film element and the film shell is same with concentration of the raw water when the reverse osmosis filter device is stopped, and an initial total dissolved solid (TDS) value of pure water is far lower than a value of a conventional reverse osmosis film filter device when the reverse osmosis filter device is in operation again after stopping.
Description
Technical field
The utility model belongs to the reverse osmosis purified water technical field, relates to a kind of reverse-osmosis filtering device.
Background technology
Common reverse osmosis membrane filt is to be made of putamina and the membrane component be located in the putamina, wherein reverse-osmosis membrane element is the core parts of realizing counter-infiltration, be wrapped on the central tube by the counter-infiltration diaphragm and form, the counter-infiltration diaphragm is a kind of artificial pellicle with certain characteristic that biological pellicle is made of simulating.(arrow and color lump GTG are higher among Fig. 1-3 referring to Fig. 1, represent that wherein the concentration of water is higher), the reverse osmosis membrane filt of this structure is when filtration operation, former water is introduced in its former water hole from putamina one end, former water enters in the reverse-osmosis membrane element from an end face of reverse-osmosis membrane element, part water filter to form pure water and flows in the central tube through the counter-infiltration diaphragm, and remaining not filtration fraction forms dense water and flows out from the other end of reverse-osmosis membrane element.The direction that water inlet direction and the concentrated water drainage of this conventional reverse osmosis membrane filt go out is consistent, owing to inevitably having the gap between reverse-osmosis membrane element and the putamina during assembling, for avoid introducing former water and filter after dense water mix, its need to be between reverse-osmosis membrane element and putamina mode by linear sealing with the putamina inner compartment, and preferably this linear sealing need to be positioned at former water inlet end face side, otherwise can cause the appearance of the problems such as poor sealing.This kind arranges structure, and above-mentioned gap forms a dead angle that accommodates dense water, can not participate in water circulation.
