Description

Technical Field

[0001] This utility model belongs to the technical field of membrane deaeration water treatment, specifically relating to a novel multi-baffle membrane contactor assembly. Background Technology

[0002] Membrane degassing water treatment is a water treatment method that uses membrane technology to remove gases such as oxygen and carbon dioxide from water. This method typically uses a specific type of membrane that can selectively allow water molecules to pass through while blocking the passage of gases, thereby achieving the degassing effect.

[0003] However, existing degassing membrane contactors generally do not use baffles, or can only set one baffle in the middle of the membrane contactor. This results in low utilization efficiency of membrane fibers or limited removal effect of a single membrane contactor. In order to achieve the removal of gas from water by the membrane contactor, existing designs often use multi-stage membrane modules connected in series to achieve the goal. This results in a large footprint for the membrane modules, the use of more pipe connections, and the inlet water pressure being affected by the piping system, which in turn affects the outlet pressure. Utility Model Content

[0004] The purpose of this invention is to provide a novel multi-baffle membrane contactor assembly to address the issues raised in the background art, such as existing degassing membrane contactors generally not using baffles, or only having one baffle in the middle of the membrane contactor, resulting in low membrane fiber utilization efficiency or limited removal effect of a single membrane contactor. In order to achieve the removal of gas from water by the membrane contactor, existing designs often use multi-stage membrane modules connected in series, which leads to a large footprint of the membrane module, the use of more pipe connections, and the inlet water pressure affecting the outlet pressure due to the pipe system.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel multi-baffle membrane contactor assembly, comprising a membrane contactor body;

[0006] The membrane contactor body has a liquid inlet on the left side, a liquid outlet at the right end, and a membrane shell inside.

[0007] A first cover is provided on the left side of the membrane contactor body, a tail cover is provided on the right side of the membrane contactor body, and connecting sleeves are arranged in an array inside the membrane contactor body.

[0008] Preferably, the connecting sleeve has insertion slots on the left and right sides, an interface in the middle of the insertion slot, insertion rings on the left and right sides, a channel connecting ring in the middle of the insertion ring, the channel connecting ring and the interface are nested together, and the insertion ring and the insertion slot are inserted together.

[0009] Preferably, a gas inlet is provided at the top of the first cover, a gas outlet is provided at the bottom of the tail cover, and a gas inlet and a gas outlet are respectively provided on the upper and lower sides of the connecting sleeve.

[0010] Preferably, a flow-dissipating baffle is provided at the middle position inside the membrane housing and connecting sleeve, and multiple membrane columns can be installed on the membrane contactor body.

[0011] Preferably, a first slow-flow chamber is provided at the rear side of the inlet of the liquid to be treated, a second slow-flow chamber is provided at the outer side of the first slow-flow chamber, and a slow-flow plate is provided at the rear side of the second slow-flow chamber.

[0012] Preferably, the flow-retarding plate has a ring array of liquid outlets inside, and the flow-retarding plate is welded to the inlet of the liquid to be treated.

[0013] Preferably, an inner cavity is provided inside the membrane shell, a channel is provided in the middle of the inner cavity, and a membrane column is wrapped around the outer side of the channel. The membrane column is formed by winding membrane filaments and is connected by adhesive.

[0014] Compared with the prior art, this utility model provides a novel multi-baffle diaphragm contactor assembly, which has the following beneficial effects:

[0015] 1. Through the configuration of the first cover, tail cover, connecting sleeve, plug slot, interface, plug ring, channel connecting ring, gas inlet, gas outlet, and flow-diverting baffle, the membrane contactor body can accommodate multiple membrane columns. This modular design makes the system easy to expand and adjust, suitable for different processing needs. The design of the first and tail covers makes the device compact and space-saving, suitable for applications with limited space. The flow-diverting baffles inside the membrane housing and connecting sleeve cause multiple deflections of liquid and gas during flow, improving contact efficiency and increasing gas removal rate. The plug ring has a channel connecting ring that nests with the interface inside the connecting sleeve, ensuring a tight fit between the membrane housing and the contactor and reducing gas and liquid leakage. The plug-in connection design of the slot and ring makes the assembly and disassembly of the membrane contactor simpler, and the maintenance and replacement of parts easier. The gas inlet on the top of the first cover and the gas outlet at the bottom of the tail cover, as well as the gas inlets and outlets on the upper and lower sides of the connecting sleeve, ensure the circulation and discharge of gas within the system, reducing gas stagnation. The liquid outlet design inside the flow buffer plate ensures the centralized discharge of liquid after treatment, improving the system's treatment efficiency. The membrane contactor's multi-baffle structure improves the removal rate and efficiency of the membrane contactor, thereby increasing the water treatment capacity of the membrane contactor, reducing the footprint, saving materials, and reducing equipment pressure loss.

[0016] 2. Through the setting of the first slow-flow chamber, the second slow-flow chamber, the slow-flow plate, and the liquid outlet, the first and second slow-flow chambers are generally used to disperse the velocity and flow rate of the inflowing liquid. This design can ensure that the liquid to be treated flows uniformly before entering the membrane contactor, avoiding uneven local flow velocity and the resulting impact and eddy current phenomena, thereby improving the overall treatment efficiency, helping to regulate the pressure fluctuations in the system, providing more stable operating conditions, and avoiding pressure shocks caused by instantaneous flow changes. Welding the slow-flow plate to the inlet of the liquid to be treated simplifies the connection structure, reduces the risk of potential leakage, and also facilitates disassembly and maintenance, and facilitates cleaning operations.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-6The present invention discloses a novel multi-baffle membrane contactor assembly, comprising a membrane contactor body 1;

[0026] The membrane contactor body 1 has a liquid inlet 2 on the left side, a liquid outlet pipe 8 on the right end, and a membrane shell 9 inside the membrane contactor body 1.

[0027] A first cover 3 is provided on the left side of the membrane contactor body 1, a tail cover 7 is provided on the right side of the membrane contactor body 1, and connecting sleeves 4 are arranged in an array inside the membrane contactor body 1.

[0028] The connecting sleeve 4 has insertion slots 15 on the left and right sides, and an interface 16 in the middle of the insertion slots 15. The membrane shell 9 has insertion rings 17 on the left and right sides, and a channel connecting ring 18 in the middle of the insertion ring 17. The channel connecting ring 18 is nested with the interface 16, and the insertion ring 17 is inserted with the insertion slot 15.

[0029] A gas inlet 6 is provided at the top of the first cover 3, and a gas outlet 5 is provided at the bottom of the tail cover 7. Gas inlets 6 and gas outlets 5 are provided on the upper and lower sides of the connecting sleeve 4, respectively.

[0030] A flow-dissipating baffle 10 is provided at the middle position inside the membrane housing 9 and the connecting sleeve 4, and multiple membrane columns 13 can be installed on the membrane contactor body 1.

[0031] A first slow-flow chamber 19 is provided at the rear side of the inlet 2 of the liquid to be treated, a second slow-flow chamber 20 is provided at the outer side of the first slow-flow chamber 19, and a slow-flow plate 21 is provided at the rear side of the second slow-flow chamber 20.

[0032] The flow retarder 21 has a ring array of liquid outlets 22 inside, and the flow retarder 21 is welded to the inlet 2 of the liquid to be treated.

[0033] An inner cavity 12 is provided inside the membrane shell 9. A channel 11 is provided in the middle of the inner cavity 12. A membrane column 13 is wrapped around the outside of the channel 11. The membrane column 13 is formed by winding membrane filaments 14 and is connected by adhesive.

[0034] In this embodiment, a novel multi-baffle membrane contactor assembly is implemented by introducing the liquid to be treated into the membrane contactor body 1 through the liquid inlet 2. The liquid is first evenly distributed through the first slow-flow chamber 19 to reduce the flow rate and ensure smooth liquid flow. After passing through the first slow-flow chamber, the liquid enters the second slow-flow chamber 20. Gas is introduced through the gas inlet 6, and the gas comes into contact with the liquid to be treated inside the membrane contactor. The gas enters the membrane shell 9 through the gas inlets 6 on the upper and lower sides of the connecting sleeve 4. The liquid to be treated passes through the membrane column 13, which is formed by winding membrane filaments 14. The structure of the membrane promotes effective contact between the liquid and the gas. The gas enters the membrane shell 9 through the channel 11, comes into contact with the liquid, and completes the gas removal process. The degassed liquid flows freely towards the outlet 22 under the action of the flow-deflecting baffle 10 inside the membrane shell 9 and the connecting sleeve 4. The treated liquid is discharged through the outlet pipe 8, achieving the expected treatment effect. The degassed liquid is discharged from the system through the outlet pipe 8 at the bottom of the tail cap 7.

[0035] like Figure 1-4 As shown, a first cover 3 is provided on the left side of the membrane contactor body 1, a tail cover 7 is provided on the right side of the membrane contactor body 1, a connecting sleeve 4 is arranged in an array inside the membrane contactor body 1, a plug-in groove 15 is provided on the left and right sides of the connecting sleeve 4, an interface 16 is provided in the middle of the plug-in groove 15, a plug-in ring 17 is provided on the left and right sides of the membrane shell 9, a channel connecting ring 18 is provided in the middle of the plug-in ring 17, the channel connecting ring 18 is nested with the interface 16, and the plug-in ring 17 is plugged into the plug-in groove 15. A gas inlet 6 is provided above the first cover 3, a gas outlet 5 is provided at the bottom of the tail cover 7, a gas inlet 6 and a gas outlet 5 are provided on the upper and lower sides of the connecting sleeve 4, a flow-diverting baffle 10 is provided in the middle of the membrane shell 9 and the connecting sleeve 4, and multiple membrane columns 13 can be installed in the membrane contactor body 1.

[0036] Preferably, the membrane contactor body 1 can be equipped with multiple membrane columns 13. This modular design makes the system easy to expand and adjust, suitable for different processing needs. The design of the first cover 3 and the last cover 7 makes the device compact and space-saving, suitable for applications with limited space. The flow-diverting baffles 10 set inside the membrane shell 9 and the connecting sleeve 4 cause the liquid and gas to be deflected multiple times during the flow process, improving the contact efficiency and increasing the gas removal rate. The insertion ring 17 has a channel connecting ring 18 inside, which is nested with the interface 16 inside the connecting sleeve 4 to ensure a tight fit between the membrane shell and the contactor, reducing gas and liquid leakage. The insertion connection design of the insertion slot 15 and the insertion ring 17 makes the assembly and disassembly of the membrane contactor easier, and facilitates maintenance and replacement. The components are more streamlined. The gas inlet 6 is located above the first cover 3, and the gas outlet 5 is located at the bottom of the tail cover 7. The gas inlet 6 and gas outlet 5 are located on the upper and lower sides of the connecting sleeve 4. At the same time, the gas inlet 6 and gas outlet 5 are connected to the vacuum pump to blow out the waste gas filtered by the membrane fiber 14, ensuring the circulation and discharge of gas within the system and reducing gas retention. The liquid outlet 22 inside the flow buffer 21 ensures the centralized discharge of liquid after treatment, improving the system's treatment efficiency. The membrane contactor has a multi-baffle structure, which improves the removal rate and efficiency of the membrane contactor, thereby increasing the water treatment capacity of the membrane contactor, reducing the floor space, saving materials, and reducing equipment pressure loss.

[0037] like Figure 5 and Figure 6 As shown, a first slow-flow chamber 19 is provided at the rear side of the inlet 2 of the liquid to be treated, a second slow-flow chamber 20 is provided at the outer side of the first slow-flow chamber 19, a slow-flow plate 21 is provided at the rear side of the second slow-flow chamber 20, and an outlet 22 is provided in a ring array inside the slow-flow plate 21. The slow-flow plate 21 is welded to the inlet 2 of the liquid to be treated.

[0038] Preferably, the first slow-flow chamber 19 and the second slow-flow chamber 20 are typically used to disperse the velocity and flow rate of the inflowing liquid. This design ensures that the liquid to be treated flows uniformly before entering the membrane contactor, avoiding uneven local flow velocity and the resulting shock and eddy current phenomena, thereby improving the overall treatment efficiency, helping to regulate pressure fluctuations within the system, providing more stable operating conditions, and avoiding pressure shocks caused by instantaneous flow changes. Welding the slow-flow plate 21 to the liquid inlet 2 simplifies the connection structure, reduces the risk of potential leakage, and also facilitates disassembly and maintenance, as well as cleaning operations.

[0039] like Figure 1-6 As shown, an inner cavity 12 is provided inside the membrane shell 9, a channel 11 is provided in the middle of the inner cavity 12, and a membrane column 13 is wrapped around the outer side of the channel 11. The membrane column 13 is formed by winding membrane filaments 14 and is connected by adhesive.

[0040] Optionally, the membrane column 13 is formed by winding membrane filaments 14. This structure effectively increases the membrane surface area, maximizing the contact area between gas and liquid, providing a larger and more efficient separation interface, and improving gas removal efficiency. The inner cavity 12 is located inside the membrane shell 9, and the central channel 11 allows liquid and gas to flow through effectively. This design is compact and makes efficient use of space, suitable for applications with limited space. The design of winding the membrane filaments 14 into the membrane column 13 ensures uniform use of membrane material, avoiding the problem of low membrane efficiency in some areas due to uneven distribution of membrane material. The adhesive connection ensures a tight connection between the membrane column and the channel 11, reducing the risk of gas and liquid leakage and improving the safety and reliability of the system.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
