[0027] As the background technology shows, how to simultaneously test reverse osmosis membrane elements from different brands has become an urgent problem to be solved.
[0028] To address the aforementioned problems, this utility model provides a membrane housing for a reverse osmosis membrane element. The membrane housing has an inlet, a concentrate outlet, and a product water outlet, and contains multiple chambers. Each chamber accommodates the reverse osmosis membrane element. Along the extending direction of the chamber, each chamber includes an inlet for the reverse osmosis membrane element and a bottom. The inlet is connected to the inlet. The concentrate outlet is corresponding to each chamber and is connected to the side wall of the chamber near the bottom. The product water outlet is corresponding to each chamber and is connected to the bottom of the chamber.
[0029] In the solution disclosed in this utility model embodiment, since the membrane housing has multiple chambers, the concentrate outlet is configured one-to-one with each chamber, and the permeate outlet is configured one-to-one with each chamber, each chamber can independently collect test data through the permeate outlet and the concentrate outlet. Thus, the reverse osmosis membrane element housing of this utility model can be used to simultaneously test reverse osmosis membrane elements of different brands, thereby improving the efficiency of reverse osmosis membrane element testing.
[0030] To make the above-mentioned objectives, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0031] Figure 1 This is a schematic diagram of the structure of a membrane housing of a reverse osmosis membrane element according to an embodiment of the present invention. Figure 2 yes Figure 1 A sectional view along the AA1 direction.
[0032] refer to Figures 1 to 2 The reverse osmosis membrane element has a membrane housing 100, which is provided with an inlet 101, a concentrate outlet 102, and a product water outlet 103. The membrane housing 100 contains multiple chambers 104 (e.g., ...). Figure 2 (as shown); wherein, the chamber 104 is used to accommodate the reverse osmosis membrane element 105, and along the extending direction of the chamber 104, the chamber 104 includes an inlet 106 for the reverse osmosis membrane element 105 and a chamber bottom 109, the inlet 106 being connected to the inlet 101; the concentrate outlet 102 is provided in a one-to-one correspondence with the chamber 104, and the concentrate outlet 102 is connected to the side wall of the chamber 104 near the chamber bottom 109; the product water outlet 103 is provided in a one-to-one correspondence with the chamber 104, and the product water outlet 103 is connected to the chamber bottom 109.
[0033] The membrane housing 100 provides physical support and housing space for the reverse osmosis membrane element 105, the inlet 101, the concentrate outlet 102, and the product outlet 103.
[0034] In this embodiment, the membrane housing 100 includes: a housing 107, which has a plurality of chambers 104 inside, and a concentrate outlet 102 and a product water outlet 103 on the housing 107.
[0035] The housing 107 is used to provide physical support and containment space for the chamber 104.
[0036] Chamber 104 provides installation space for reverse osmosis membrane element 105.
[0037] It should be noted that, since the membrane housing 100 has multiple chambers 104, the concentrate outlet 102 is configured one-to-one with each of the chambers 104, and the product water outlet 103 is configured one-to-one with each of the chambers 104, each chamber 104 can independently collect test data through the product water outlet 103 and the concentrate outlet 102. Thus, through the membrane housing 100 of the reverse osmosis membrane element 105 of this utility model, reverse osmosis membrane elements 105 of different brands can be tested simultaneously, thereby improving the testing efficiency of the reverse osmosis membrane element 105.
[0038] In this embodiment, the chamber 104 is used to place the reverse osmosis membrane element 105. Along the extending direction of the chamber 104, the chamber 104 includes the inlet 106 of the reverse osmosis membrane element 105 and the bottom 109 of the chamber. The inlet 106 is connected to the inlet 101.
[0039] The inlet 106 is used to insert or remove the reverse osmosis membrane element 105 into or from the chamber 104.
[0040] The inlet 101 is used to introduce water flow into the membrane housing 100.
[0041] It should be noted that the inlet 106 is connected to the water inlet 101, which facilitates the flow of water through the reverse osmosis membrane element 105 in the chamber 104 when testing the reverse osmosis membrane element 105, thereby improving the accuracy and efficiency of the test.
[0042] The bottom 109 of the chamber is used to form a closed structure with the inner wall of the chamber 104 to ensure that the chamber 104 remains stable when subjected to water pressure and mechanical stress.
[0043] In this embodiment, the length of the chamber 104 is greater than the length of the reverse osmosis membrane element 105 along the direction from the inlet 101 to the bottom 109 of the chamber, which facilitates the insertion and removal of the reverse osmosis membrane element 105.
[0044] Specifically, refer to Figure 2The reverse osmosis membrane element 105 is placed in the chamber 104. The bottom of the reverse osmosis membrane element 105 is located at the position of the dotted line in the figure. The product water discharge pipe is connected to the central pipe (not shown in the figure) in the reverse osmosis membrane element 105. The product water discharge pipe will support the reverse osmosis membrane element 105 to ensure that the reverse osmosis membrane element 105 maintains a stable position in the chamber 104 and that the reverse osmosis membrane element 105 is at a certain distance from the bottom 109 of the chamber.
[0045] In this embodiment, the multiple chambers 104 are distributed circumferentially along the membrane shell 100, which helps to make full use of the internal space of the membrane shell 100 and improve the overall space utilization rate.
[0046] In this embodiment, along the direction from the end cap to the housing 107, the length of the housing 107 is greater than the length of the chamber 104, which correspondingly increases the length of the product water discharge pipeline. During the testing of the reverse osmosis membrane element 105, this helps to increase the flow path of the water, thereby increasing the contact time between the water and the reverse osmosis membrane element 105, and thus improving the filtration effect of the reverse osmosis membrane element 105.
[0047] Along the direction from the end cap to the housing 107, the distance between the bottom of the chamber 104 and the bottom of the housing 107 should not be too large or too small. If the distance between the bottom of the chamber 104 and the bottom of the housing 107 is too large, the volume of the membrane housing 100 will easily increase, thereby increasing the cost of manufacturing the membrane housing 100 of the reverse osmosis membrane element 105. If the distance between the bottom of the chamber 104 and the bottom of the housing 107 is too small, the space between the bottom of the chamber 104 and the bottom of the housing 107 will be too narrow, which will easily form a dead zone for water flow, making water flow obstructed and affecting the accuracy of the reverse osmosis membrane element 105 test. Therefore, in this embodiment, along the direction from the end cap to the housing 107, the distance between the bottom of the chamber 104 and the bottom of the housing 107 is 10 cm to 15 cm.
[0048] The bottom of chamber 104 refers to the bottom of chamber 104 on the side opposite to the inlet 106 in the direction from the end cap toward the housing 107.
[0049] The bottom of housing 107 refers to the bottom of housing 107 on the side opposite to the inlet 106, in the direction from the end cap toward housing 107.
[0050] In this embodiment, there are 6 chambers 104. In other embodiments, the number of chambers can be increased according to actual needs; for example, the number of chambers may be greater than 6 or less than 6.
[0051] In this embodiment, the concentrate outlet 102 is provided in a one-to-one correspondence with the chamber 104, and the concentrate outlet 102 is connected to the side wall of the chamber 104 near the bottom 109 of the chamber.
[0052] Concentrate outlet 102 is used to discharge concentrated water.
[0053] Concentrated water refers to the water containing pollutants and impurities that fails to pass through the reverse osmosis membrane element 105 after filtration.
[0054] It should be noted that the concentrate outlet 102 is provided in a one-to-one correspondence with the chamber 104, and the concentrate outlet 102 is connected to the chamber 104, so that each chamber 104 can independently collect data through the concentrate outlet 102.
[0055] It should also be noted that the concentrate outlet 102 is connected to the side wall of the chamber 104 near the bottom 109 of the chamber, which is conducive to the rapid discharge of concentrate and reduces the residence time of concentrate in the chamber 104, thereby preventing concentrate from accumulating on the surface of the reverse osmosis membrane element 105.
[0056] In this embodiment, the membrane housing 100 further includes a concentrate discharge pipe 110, which penetrates the side wall of the housing 107 away from the inlet 106. One end of the concentrate discharge pipe 110 is connected to the chamber 104, and the other end is the concentrate outlet 102 connected to the outside of the housing 107.
[0057] The concentrate discharge pipe 110 is used to connect the chamber 104 and the concentrate outlet 102.
[0058] It should be noted that the concentrated water discharge pipe 110 passes through the side wall of the housing 107 away from the inlet 106, which helps to avoid interference between the concentrated water and the incoming water flow during the discharge process, thereby reducing water flow resistance and improving test efficiency.
[0059] It should also be noted that one end of the concentrated water discharge pipe 110 is connected to the chamber 104, and the other end is the concentrated water outlet 102 connected to the outside of the shell 107, so that the concentrated water can be smoothly discharged from the chamber 104 to the outside of the shell 107.
[0060] In this embodiment, the water outlet 103 is provided in a one-to-one correspondence with the chamber 104, and the water outlet 103 is connected to the bottom 109 of the chamber.
[0061] The water outlet 103 is used to collect the pure water produced after filtration through the reverse osmosis membrane element 105.
[0062] Specifically, the water outlet 103 is provided in a one-to-one correspondence with the chamber 104, and the water outlet 103 is connected to the chamber 104, so that each chamber 104 can independently collect data through the water outlet 103.
[0063] It should be noted that the water outlet 103 is connected to the bottom 109 of the chamber, which helps to ensure that the water flows fully through the reverse osmosis membrane element 105 in the chamber 104, thereby improving the quality of the produced pure water.
[0064] It should also be noted that the product water outlet 103 is connected to the bottom 109 of the chamber, and the concentrate outlet 102 is connected to the side wall of the chamber 104 near the bottom 109 of the chamber. This facilitates the separation of the concentrate outlet 102 and the product water outlet 103, thereby reducing the probability of forming dead zones in the water flow and correspondingly reducing the residence time of water in the chamber 104, thus improving the filtration efficiency of the reverse osmosis membrane element 105.
[0065] In this embodiment, the membrane housing 100 further includes a water discharge pipe 111, which penetrates the bottom of the housing 107 on the side opposite to the inlet 106. One end of the water discharge pipe 111 is connected to the chamber 104, and the other end is the water outlet 103 connected to the outside of the housing 107.
[0066] The water discharge pipe 111 is used to connect the chamber 104 and the water outlet 103.
[0067] It should be noted that the product water discharge pipe 111 passes through the bottom of the housing 107 on the side opposite to the inlet 106, and after the reverse osmosis membrane element 105 is installed, the product water discharge pipe 111 is connected to the central pipe of the reverse osmosis membrane element 105. This ensures that after the water enters the housing 107, it must be filtered by the reverse osmosis membrane element 105 before reaching the product water discharge pipe 111. This helps reduce the possibility that the water will bypass the reverse osmosis membrane element 105 and directly enter the product water discharge pipe 111, thereby ensuring that all collected water has undergone sufficient filtration.
[0068] Specifically, the central tube is located at the center of the reverse osmosis membrane element 105 and is used to collect pure water filtered by the reverse osmosis membrane element 105.
[0069] It should also be noted that one end of the water discharge pipe 111 is connected to the chamber 104, and the other end is the water outlet 103 connected to the outside of the shell 107, so that pure water can be discharged from the chamber 104 to the outside of the shell 107 and avoid mixing with other water flows (such as concentrated water).
[0070] In this embodiment, the membrane shell 100 further includes an end cap 112, which is connected to the shell 107. The end cap 112 is located on the side of the inlet 106 of the chamber 104, and the water inlet 101 is provided in the end cap 112.
[0071] The end cap 112, connected to the housing 107, serves as a seal to prevent water leakage from the connection of the membrane housing 100, thus ensuring the sealing and reliability of the membrane housing 100.
[0072] Specifically, the end cap 112 is connected to the housing 107. The end cap 112 is located on the side of the inlet 106 of the chamber 104. The end cap 112 is provided with the water inlet 101, which helps to ensure that after the water flows into the end cap 112 through the water inlet 101, it can flow through the inlet 106 and pass through the reverse osmosis membrane element 105 in each chamber 104 to achieve water filtration.
[0073] In this embodiment, the end cap 112 is detachably connected to the housing 107, which facilitates the replacement of the reverse osmosis membrane element 105 inside the housing 107.
[0074] Specifically, the end cap 112 is connected to the housing 107 by threads.
[0075] In other embodiments, the end cap and the housing can be connected by a snap-fit structure, or the end cap and the housing can also be connected by bolts and nuts.
[0076] In other embodiments, the end cap and the housing may be non-detachably connected, depending on actual needs.
[0077] In this embodiment, the end cap 112 is provided with a water inlet storage cavity 113, which is connected to the water inlet 101. The water inlet 101 is connected to the placement port 106 through the water inlet storage cavity 113.
[0078] The water inlet storage chamber 113 is used to temporarily store the incoming water flow and to buffer the water flow pressure.
[0079] It should be noted that after the water flows into the water inlet storage chamber 113 through the water inlet 101, it will stay temporarily in the water inlet storage chamber 113. The water flow can be evenly distributed in the water inlet storage chamber 113. Then, the evenly distributed water flow enters each chamber 104 through the inlet 106, thereby ensuring that the reverse osmosis membrane element 105 in each chamber 104 can obtain a uniform water flow.
[0080] Specifically, the length of the water inlet storage chamber 113 should not be too long or too short along the direction from the water inlet 101 to the water distribution assembly. If the length of the water inlet storage chamber 113 is too long, the length of the end cap 112 will increase accordingly, thereby increasing the manufacturing cost of the end cap 112; if the length of the water inlet storage chamber 113 is too short, there will not be enough time and space for the water to be evenly distributed before entering the chamber 104, resulting in poor uniformity of water flow to the reverse osmosis membrane element 105 in each chamber 104. Therefore, in this embodiment, the length of the water inlet storage chamber 113 along the direction from the water inlet 101 to the water distribution assembly is 10 cm to 15 cm.
[0081] In this embodiment, the membrane housing 100 further includes a water distribution assembly 114, which is located in the water inlet storage cavity 113 and is fixed to the inner wall of the water inlet storage cavity 113.
[0082] The water distribution assembly 114 is used to evenly distribute the water flow in the water inlet storage chamber 113 to each chamber 104.
[0083] It should be noted that the water distribution assembly 114 is located in the water inlet storage chamber 113, that is, the water distribution assembly 114 is in direct contact with the water flow in the water inlet storage chamber 113, which is beneficial to further distribute the water flow evenly to each chamber 104.
[0084] It should also be noted that the water distribution assembly 114 is fixed to the inner wall of the water inlet storage cavity 113, which helps to ensure that the water distribution assembly 114 remains stable under the impact of water flow and reduces the probability of the water distribution assembly 114 shifting or loosening.
[0085] In this embodiment, the water distribution assembly 114 includes a water pressure buffer assembly 115 and a water flow distribution assembly 116, which are arranged sequentially along the direction from the end cap 112 to the housing 107.
[0086] The water pressure buffer assembly 115 is used to buffer the pressure of the water flow in the water inlet chamber 113, and also to distribute the water flow in the water inlet chamber 113 evenly.
[0087] The water flow distribution component 116 is used to further distribute the water flow in the water inlet chamber 113 evenly.
[0088] It should be noted that the water pressure buffer assembly 115 and the water flow distribution assembly 116 are arranged sequentially along the direction from the end cap 112 to the housing 107. This arrangement helps to buffer the pressure of the water flow in the inlet water storage chamber 113 first, and then distribute the water flow in the inlet water storage chamber 113 evenly. This improves the uniformity of water flow to the reverse osmosis membrane element 105 in each chamber 104, thereby improving the accuracy of testing the reverse osmosis membrane element 105.
[0089] The distance between the water pressure buffer assembly 115 and the water flow distribution assembly 116 should not be too large or too small. If the distance between the water pressure buffer assembly 115 and the water flow distribution assembly 116 is too large, the energy of the water flow passing through the water pressure buffer assembly 115 will easily accumulate again before reaching the water flow distribution assembly 116, thereby increasing the water pressure. If the distance between the water pressure buffer assembly 115 and the water flow distribution assembly 116 is too small, the water flow will not have enough space to fully diffuse and stabilize after passing through the water pressure buffer assembly 115, resulting in poor uniformity of the water flow distributed to each chamber 104. Therefore, in this embodiment, the distance between the water pressure buffer assembly 115 and the water flow distribution assembly 116 is 15 cm to 25 cm.
[0090] In this embodiment, a slot 117 is provided on the inner wall of the water inlet temporary storage cavity 113; the water distribution assembly 114 is engaged with the slot 117.
[0091] The slot 117 is used to provide a stable installation position for the water distribution assembly 114, ensuring that the water distribution assembly 114 will not shift or loosen under the impact of water flow.
[0092] Specifically, the water distribution component 114 is engaged with the slot 117, which facilitates the installation and disassembly of the water distribution component 114, thereby reducing maintenance costs.
[0093] In this embodiment, the water distribution component 114 satisfies at least one of the following conditions: the water distribution component 114 includes a water pressure buffer component 115, the water pressure buffer component 115 includes an inlet grid; the water distribution component 114 includes a water flow distribution component 116, the water flow distribution component 116 includes a water distributor.
[0094] The inlet grid is a porous structure that can effectively disperse water flow and thus buffer water pressure.
[0095] The water distributor is composed of multiple evenly distributed flow guide grilles, which can further distribute the water flow evenly to each chamber 104.
[0096] Accordingly, this utility model embodiment also provides a reverse osmosis membrane testing device.
[0097] Figure 3 This is a schematic diagram of an embodiment of the reverse osmosis membrane testing device of this utility model.
[0098] refer to Figure 3 and combined Figure 1 and Figure 2 The reverse osmosis membrane testing device 200 includes: a membrane housing 100 as described in any embodiment of the present invention; and at least one reverse osmosis membrane element 105, which is placed in any of the chambers 104 of the membrane housing 100.
[0099] The reverse osmosis membrane element 105 is used to remove total organic carbon from water.
[0100] It should be noted that, since the reverse osmosis membrane device 200 includes the membrane housing 100 described in any embodiment of the present invention, the reverse osmosis membrane device 200 can test the reverse osmosis membrane element 105 in each chamber 104, thereby enabling simultaneous testing of reverse osmosis membrane elements 105 from different brands, and thus improving the efficiency and accuracy of the reverse osmosis membrane device 200 in testing the reverse osmosis membrane element 105.
[0101] In this embodiment, the reverse osmosis membrane testing device 200 further includes an external instrument 201, which is connected to the inlet 101, concentrate outlet 102 and product outlet 103 respectively.
[0102] External instrument 201 is used to acquire test data for inlet 101, concentrate outlet 102 and product outlet 103 respectively.
[0103] It should be noted that the external instrument 201 is connected to the inlet 101, concentrate outlet 102 and product water outlet 103 respectively, which is conducive to real-time monitoring and data collection of the reverse osmosis membrane device 200, thereby improving the testing efficiency and accuracy.
[0104] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
