Abstract
The utility model relates to a spiral rolled film element which comprises a plurality of standard films, runner cloth and a fine structure mesh, wherein the standard films are directly twisted on a center water generating pipe; the sizes, the dimensions and the shapes of the standard films are identical. The spiral rolled film element is characterized in that at least one non-standard film which is smaller than each of the standard films is clamped in the films; the end of the non-standard film and the ends of the standard film are aligned or mutually stagger for identical distances. According to the requirements of the water yield and the diameter of the film element, the utility model is additionally provided with at least one non-standard film whose size is different from that of the standard films on the basis of the standard films. Thus, the spiral rolled film element is composed of the standard films with the same size, and at least one non-standard film whose size is different from that of the standard films, which achieves the purpose of increasing effective film area and the water yield. While water pollution is eliminated, the film element with an arbitrary water yield and an arbitrary diameter of the utility model can be conveniently made. The utility model has simple structure so that primary materials are saved.
Description
Technical field
The utility model relates to a kind of a kind of membrane separation device of removing impurity such as silt in the water, mud, colloid, microorganism, virus, organic matter and inorganic salts, especially refers to spiral wound film element.
Background technology
At present, the structure of known spiral wound film element is by the center water producing pipe, several pieces sizes, the on all four standard size diaphragm of size and dimension, and selvage guide, fine-structure mesh, outer adhesive tape and sealing ring constitute.The aquifer yield of this membrane component and the diameter of membrane component are subjected to the restriction of used integer sheet standard film, can't produce the membrane component of arbitrary diameter and aquifer yield.
Summary of the invention
For overcome the essential used same size of existing spiral wound film element, big or small standard diaphragm rolls, make the deficiency that element diameter and aquifer yield are restricted, the utility model provides a kind of spiral wound film element, this spiral wound film element can not only remove in the water impurity such as silt, mud, colloid, microorganism, virus, organic matter and inorganic salts, can also adopt the different diaphragm of size dimension to make, thereby obtain the spiral wound film element of arbitrary diameter and aquifer yield.
A kind of spiral wound film element that the utility model adopted, comprise several pieces sizes that directly are wrapped on the water producing pipe of center, the standard diaphragm of size and dimension unanimity, selvage guide and fine-structure mesh, it is characterized in that, in described several pieces diaphragms, accompany a slice non-standard diaphragm littler than standard diaphragm at least, the end of this non-standard diaphragm aligns with the end of standard diaphragm or staggers same distance mutually.
Adopted above-mentioned technical solution, promptly on the basis of standard diaphragm, requirement according to aquifer yield and membrane component diameter, increased the non-standard diaphragm that a slice and standard film chip size at least vary in size, spiral wound film element is made of with at least one chip size size non-standard diaphragm different with the standard diaphragm jointly the standard diaphragm of several pieces size unanimities like this, has reached the purpose that increases effective film area and aquifer yield.The utility model can be produced the membrane component of any aquifer yield and diameter easily when removing water pollutant, simple in structure, has saved raw material.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, size, the standard diaphragm 4 of size and dimension unanimity and fine-structure mesh 3 diameters are wrapped on the center water producing pipe 1, roll from inside to outside, diameter is overstriking gradually, between two standard diaphragms 4, accompany the diaphragm 5 of a slice off-standard size, the end alignment of all diaphragms, the equal distance that perhaps staggers bonds together back-to-back, whole finished film element is contained in the special container, water inlet sealing ring 6 guarantees all water inlets membrane component of all flowing through, and pure water sealing ring 2 separates into water and filtered water, and water inlet is being divided into filtered water and condensed water two parts through behind the membrane filtration, filtered water flows to center water producing pipe 1, and condensed water is drawn container.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong within the category of the present utility model, should be defined by the claims.
Claims (1)
1. spiral wound film element, comprise several pieces sizes that directly are wrapped on the water producing pipe of center, the standard diaphragm of size and dimension unanimity, selvage guide and fine-structure mesh, it is characterized in that, in described several pieces diaphragms, accompany a slice non-standard diaphragm littler than standard diaphragm at least, the end of this non-standard diaphragm aligns with the end of standard diaphragm or staggers same distance mutually.
