Abstract
The invention discloses a shell of an inverse osmosis filter, which comprises a main shell and a shell cover, wherein the shell cover is provided with a water inlet, the main shell is provided with a pure water opening and a waste water opening, the main shell is also provided with the other water inlet, and after a side-flow type roll type film element is installed in the shell, the water inlet and the other water inlet are respectively only communicated with water inlets positioned at both ends of the side-flow type roll type film element and besides a central water production pipe, the waste water opening is only communicated with a waste water outlet on the surface of the circumferential side of the side-flow type roll type film element, and the pure water opening is only communicated with a pure water outlet of the central water production pipe of the side-flow type roll type film element. The improved shell has the advantage that the shell can be matched with the newly invented side-flow type roll type film element. The new inverse osmosis filter formed by matching the shell in the structure with the newly invented side-flow type roll type film element overcomes the defect that a concentration polarization phenomenon easily occurs on the surface of a traditional roll type film element, solves the pollution problem of the film element, and prolongs the service life of the film element.
Description
Technical field
The invention belongs to counter-infiltration water purification technology field, relate to reverse osmosis filter, relate in particular to the housing of reverse osmosis filter.
Background technology
Known coiled reverse osmosis membrane element is the water purification diaphragm group that is made up of pure water water conservancy diversion net, counter-infiltration diaphragm, the stack of water inlet water conservancy diversion net to be wrapped on the water producing pipe of center form; Wherein the counter-infiltration diaphragm is folded; In the water inlet flow channel that constitutes between the inner surface of said water inlet water conservancy diversion net after the counter-infiltration diaphragm is folding; In the product water flow passage that constitutes between the outer surface of said pure water water conservancy diversion net after the counter-infiltration diaphragm is folding; This coiled reverse osmosis membrane element be with the end face dual-side that produces water flow passage and away from a side of center water producing pipe with the bonding opening that makes the product water flow passage have water producing pipe of glue towards the center; Water purification diaphragm group is behind the water producing pipe of the center of winding, and whole outer surface is carried out environmental sealing with outer adhesive tape.The rolling ro components of this structure; It is from the inflow water inlet flow channel of an end face of element; Part water filters the formation pure water through the counter-infiltration diaphragm and flows in the water producing pipe of center along pure water water conservancy diversion net, and the remaining dense water that forms that filters flows out from the other end of element along the water inlet water conservancy diversion net in the water inlet flow channel.The direction that the water inlet direction and the concentrated water drainage of this reverse-osmosis membrane element go out is consistent, but because runner is wide, flow process is short; The speed of water inlet in runner is slower, and the film surface is easy to generate the concentration polarization phenomenon, thereby causes membrane component to pollute; Make salt rejection rate and aquifer yield reduce the membrane component lost of life.
For this reason; The applicant has invented a kind of coiled reverse osmosis membrane element and (has proposed patent application to Patent Office of the People's Republic of China; Number of patent application is 200910201739.8), this coiled reverse osmosis membrane element is a kind of lateral flow type coiled reverse osmosis membrane original paper (hereinafter to be referred as a lateral flow type rolled film original paper), this pleurodiaphragmatic in terspace spare has overcome the shortcoming that existing membrane component film surface is prone to produce the concentration polarization phenomenon; Solve the membrane component pollution problem, prolonged the service life of membrane component.
But the housing of reverse osmosis filter of the prior art can't use with above-mentioned neoteric coiled reverse osmosis membrane element coupling.
