Description

Technical Field

[0001] The utility model relates to a modular component, in particular to a forward osmosis membrane modular component, and belongs to the technical field of forward osmosis. Background Art

[0002] Forward osmosis is a natural phenomenon, but it is also a new type of concentration-driven membrane separation technology developed in recent years. It is a membrane separation process that relies on the osmotic pressure difference on both sides of the selective permeable membrane as a driving force to spontaneously realize water transfer. It is one of the hot spots in the field of membrane separation research in the world. Forward osmosis refers to the process in which water flows from the area on the side with higher water chemical potential (or lower osmotic pressure) through the selective permeable membrane to the area on the side with lower water chemical potential (or higher osmotic pressure). Two solutions with different osmotic pressures are placed on both sides of the selective permeable membrane, one is the raw material solution with lower osmotic pressure, and the other is the driving solution with higher osmotic pressure. Forward osmosis uses the osmotic pressure difference of the solutions on both sides of the membrane as a driving force, so that water can spontaneously pass through the selective permeable membrane from the raw material side to the driving solution side. When an external pressure less than the osmotic pressure difference is applied to the solution on the side with high osmotic pressure, water will still flow from the raw material liquid side to the driving solution side. This process is called pressure-damped osmosis. The driving force of pressure-damped osmosis is still osmotic pressure, so it is also a forward osmosis process.

[0003] Due to the application of forward osmosis technology, its principle is driven by concentration difference potential energy, and water molecules can be separated without high pressure or ultra-high pressure. Therefore, its membrane is extremely thin, and its component form must have the requirements of rigidity to overcome external stress, while not having to consider the stress caused by high-intensity pressure. Its main application is in seawater desalination, landfill leachate, and chemical food and drug material concentration. The integration method should be small in size and high in efficiency.

[0004] In order to meet the above requirements, the present application proposes a forward osmosis membrane modular component. Utility Model Content

DETAILED DESCRIPTION

[0029] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0030] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-7 As shown, an embodiment of the utility model provides a forward osmosis membrane modular component, which is composed of a packaging mechanism 10 and a main body mechanism 20. The packaging mechanism 10 provides packaging, enhances external mechanical stress, and realizes pipeline connection with the outside world. The main body mechanism 20 provides two spaces decomposed by membranes and is isolated from the external space to realize the correct utilization of concentration difference.

[0032] like Figure 1-3 As shown, the packaging mechanism 10 includes a first end plate 11 and a second end plate 12 , one side of the first end plate 11 and the second end plate 12 are both integrally formed with a protrusion 13 , and one side of the first end plate 11 and the second end plate 12 are both opened with a countersunk crimping hole 16 .

[0033] In one embodiment, the height of the first end plate 11 and the second end plate 12 are both 9 mm, and the volume of the entire membrane assembly is 368 mm*306 mm*280 mm.

[0034] In one embodiment, the first end plate 11 and the second end plate 12 are welded or bonded to the component plate 21 on the inner side, and are press-connected to the metal plate on the outer side.

[0035] In one embodiment, the countersunk crimping hole 16 and the crimping pipe fitting are sealed with an O-ring, the U-PVC pipe fitting obeys the compression stress of the first end plate 11 and the second end plate 12, and the rubber O-ring is combined with the component block body to achieve sealing, and the first end plate 11 and the second end plate 12 are threaded to connect the metal outer wire pipe fitting to the equipment.

[0036] like Figure 1-7As shown, the main mechanism 20 includes a component block, which is composed of a component plate 21. The component plate 21 is divided into two sides, A and B. The component plate 21 is arranged between the first end plate 11 and the second end plate 12. A diaphragm groove 35 is integrally formed on one side of the component plate 21. A first circulation hole 24 and a second circulation hole 25 are evenly distributed on one side of the component plate 21. A third circulation hole 26 and a fourth circulation hole 27 are evenly distributed on one side of the component plate 21. A first through hole 28 and a second through hole 29 are respectively opened on one side of the component plate 21. The first through hole 28 is the inlet of the drawn liquid, which obeys its positive pressure fluid power and enters the component block longitudinally. It enters between the diaphragm and the component plate 21 from the fourth circulation hole 27, walks through half of the component plate 21, flows from the second circulation hole 25 to the B side, and part of it flows from the first circulation hole 24 to the collecting port on the left side of the B side, forcing the drawn liquid to spread along the waterway 34 to the third circulation hole 26 and then return to the fourth circulation hole 27 on the A side, and flow away from the second through hole 29 with negative pressure fluid power. A third through hole 31 and a fourth through hole 32 are respectively opened on one side of the component plate 21, and the first through hole 28, the second through hole 29, the third through hole 31 and the fourth through hole 32 are aligned with the countersunk crimping hole 16, and a flow channel 36 is integrally formed on one side of the component plate 21.

[0037] In one embodiment, each module is designed to have an effective working area of 10 square meters, a single single-sided diaphragm has an effective working area of 255mm*225mm, and each module should be installed with at least 174 diaphragms, that is, 87 module panels 21. The thickness of the module panel 21 is 3mm.

[0038] In one embodiment, first through-thread holes 14 are evenly distributed on one side of the first end plate 11 and the second end plate 12, first positioning holes 15 are evenly distributed and symmetrically distributed on one side of the first end plate 11 and the second end plate 12, second through-thread holes 22 are evenly distributed on one side of the component plate 21, and second positioning holes 23 are evenly distributed and symmetrically distributed on one side of the component plate 21.

[0039] In one embodiment, since the thickness of the diaphragm is too small and the component plate 21 is a plate material, it may cause insufficient space due to tight fitting. One side of the component plate 21 is evenly distributed with integrated balls 33. The diameter of the balls 33 is 1 mm and they are evenly arranged so that there is enough space between the diaphragm and the component plate 21 for the flow of the drawn liquid. One side of the component plate 21 is evenly distributed with integrated waterways 34. The spherical height of the waterways 34, the component plate 21, and the small balls 33 are equal, so as to limit the standardized flow of the drawn liquid.

[0040] In one embodiment, the secondary space is formed by stacking the component plates 21 of each double-sided packaging diaphragm in sequence, so that the diaphragms are close to each other and space is created in the middle. In order to prevent the diaphragms from fitting tightly, a bidirectional PE mesh with warp φ0.2 and weft φ0.4 is used for padding before stacking to support the internal space.

[0041] In one embodiment, the secondary space is effectively isolated from the primary space by a tight package between the diaphragm and the component plate 21, such as ultrasonic welding, eddy current hot welding, adhesives, etc. The secondary space is isolated from the external physical environment and is integrated with the component plate 21 package.

[0042] In one embodiment, the component panels 21 are tightly packaged together by sealing lines with each other, such as by ultrasonic welding, hot melt welding, adhesives, etc., and the third through hole 31 and the fourth through hole 32 are included, while the water inlet ramps of the first through hole 28 and the second through hole 29 are retained, so that the secondary space and the primary space are completely isolated from the external physical environment, and the connection strength between the component panels 21 is ensured.

[0043] When the utility model is working: the drawn liquid passes through the first through hole 28 and obeys its positive pressure fluid power, enters the component block longitudinally from the fourth circulation hole 27 on the A side and enters between the diaphragm and the component plate 21, wanders through half of the component plate 21, flows from the second circulation hole 25 to the B side, and part of it flows from the first circulation hole 24 to the left side collecting port of the B side. Because it is restricted by the package between the component plates 21 and the component plates 21, it cannot form a loop, so the drawn liquid is forced to spread along the waterway 34 to the third circulation hole 26 and then return to the fourth circulation hole 27 on the A side, and flows away from the second through hole 29 with negative pressure fluid power, thereby forming a waterway cycle that provides another adjacent space with a sufficiently high concentration difference of drawn liquid, creating potential energy continuity, the spheres 33 arranged on both sides of the component plate 21 make there is enough space between the diaphragm and the component plate 21 for the drawn liquid to flow, and the waterways 34 with the same spherical height as the component plate 21 and the small spheres 33 are respectively arranged on both sides of the component plate 21 to limit the standardized flow of the drawn liquid.

[0044] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
