Description

Technical Field

[0001] This utility model relates to the field of gas-liquid mixing technology, and in particular to a high-purity gas-liquid mixing device. Background Technology

[0002] In engineering projects, when gas-liquid mixing is required, the gas often contains water vapor and impurities, which can significantly affect the purity of the mixture. To address this issue, micro / nano hollow membrane filaments are commonly used. These filaments are permeable to air but impermeable to water, isolating water vapor from the gas on their surface. Clean gas then passes through the micropores on the filaments to mix with the liquid inside the tube. Furthermore, the micropores on the filaments can also trap fine particles, bacteria, and other impurities on their surface, thus achieving a purification effect.

[0003] For example, Chinese invention patent application number CN202111243531.X discloses a gas-liquid mixing filter element and a gas-liquid mixing method. It includes an upper cover, a lower cover, a filter element housing, a central tube, and a central connector. The upper and lower covers are detachably connected to the upper and lower ends of the filter element housing, respectively. The central tube is located inside the filter element housing, and multiple hollow fiber membrane filaments are arranged circumferentially on the outer side of the central tube. Each hollow fiber membrane filament has multiple small holes on its sidewall. Liquid flows inside the membrane filaments, while gas flows outside. By applying a certain pressure to the gas, it is forced to enter the liquid passage inside the hollow fiber membrane filaments through the tiny holes on the sidewalls, thereby achieving gas-liquid mixing. Furthermore, addressing the drawbacks of hollow fiber membranes, such as narrow passages, small pore size, and susceptibility to clogging by impurities, the aforementioned patent employs a threaded connection between the upper cover and the filter element seat to achieve simple and quick assembly and disassembly of the gas-liquid mixing filter element, solving the problem that it is difficult for users to replace the hollow fiber gas-liquid mixer themselves when it becomes clogged.

[0004] However, the above-mentioned gas-liquid mixing filter element and gas-liquid mixing method only solve the problem of quick filter element replacement, but do not solve the problem of when the filter element needs to be replaced. When the filter element is clogged, it is difficult to detect in time, which affects the gas-liquid mixing effect and the purity of the mixture. There is also a risk of explosion due to excessive internal pressure caused by the inability of gas to flow. Utility Model Content

[0005] The purpose of this invention is to provide a high-purity gas-liquid mixing device that can detect blockages in a timely manner, ensure gas-liquid mixing effect, and improve safety.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a high-purity gas-liquid mixing device, including a shell, inside which a membrane filter element formed by multiple membrane filaments is sleeved; the two ends of the shell are respectively provided with a liquid inlet and a gas-liquid mixing outlet, the two ends of the membrane filter element are respectively connected to the liquid inlet and the gas-liquid mixing outlet, and the shell is connected to a gas inlet and a pressure detection port, and a pressure monitoring device is provided in the pressure detection port.

[0008] Furthermore, a water quality monitoring device is installed inside the gas-liquid mixing outlet.

[0009] Furthermore, a concentration monitoring device is installed inside the air pressure detection port.

[0010] Furthermore, the pressure monitoring device, water quality monitoring device, and concentration monitoring device are all electrically connected to a processing module, and the processing module is wired to an alert module.

[0011] Furthermore, the end faces of the membrane fiber filter element at both ends are respectively attached to the inner end faces of the outer shell at both ends.

[0012] Furthermore, the gas inlet is adjacent to the liquid inlet, and the pressure detection port is adjacent to the gas-liquid mixing outlet.

[0013] Furthermore, the outer shell, membrane filter element, liquid inlet, and gas-liquid mixing outlet are coaxial, and the axis of the gas inlet is approximately perpendicular to the axis of the membrane filter element.

[0014] Furthermore, the inner diameters of both the liquid inlet and the gas-liquid mixture outlet are smaller than the inner diameter of the outer casing.

[0015] Furthermore, the outer shell is made of a transparent material.

[0016] Due to the adoption of the above structure, the beneficial effects of this utility model are as follows:

[0017] This invention features a liquid inlet and a gas inlet on the outer casing. When the liquid inlet and gas inlet are connected to external gas and liquid sources respectively, liquid enters the membrane fibers of the filter element through the liquid inlet. Simultaneously, gas enters the membrane fibers sequentially through the gas inlet, the outer casing, and the filter element, thus achieving gas-liquid mixing and ultimately forming a high-purity mixture that exits from the gas-liquid mixing outlet. Furthermore, by installing a pressure monitoring device in the pressure detection port, when the membrane fibers become clogged, gas permeability decreases, making it difficult for gas to enter the membrane fibers and mix with the liquid. This results in excessive gas retention between the outer casing and the filter element, increasing the pressure, which is detected by the pressure monitoring device. Users can promptly detect blockages through pressure changes monitored by the pressure monitoring device, prompting timely handling or replacement to ensure gas-liquid mixing effect and safety, and to ensure the continuous production of high-purity mixtures.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," "third," and "fourth," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please refer to Figures 1 to 3 This utility model provides a high-purity gas-liquid mixing device, including a shell 3, inside which a membrane filter element 4 formed by multiple membrane filaments is sleeved; the two ends of the shell 3 are respectively provided with a liquid inlet 1 and a gas-liquid mixing outlet 6, the two ends of the membrane filter element 4 are respectively connected to the liquid inlet 1 and the gas-liquid mixing outlet 6, and the shell 3 is connected with a gas inlet 2 and a pressure detection port 5, and a pressure monitoring device 7 is provided in the pressure detection port 5.

[0029] In this specific embodiment, the liquid enters the membrane fiber through the liquid inlet 1. Due to the air-permeable but water-impermeable properties of the membrane fiber, the liquid will flow along the membrane fiber towards the gas-liquid mixing outlet 6. At the same time, the gas enters the interior of the outer shell 3 through the gas inlet 2, and the pressure of the gas inside the outer shell 3 is greater than the pressure of the liquid inside the membrane fiber. The gas between the outer shell 3 and the membrane fiber will enter the interior of the membrane fiber through the micropores on the membrane fiber and mix with the liquid, thereby realizing gas-liquid mixing. Water vapor, impurities, etc. in the gas will be isolated on the surface of the membrane fiber, and finally a high-purity mixture will be formed and discharged from the gas-liquid mixing outlet 6.

[0030] The pressure monitoring device 7 is a gas pressure sensor. When the membrane fibers and their micropores become blocked, gas permeability decreases, making it difficult for gas between the outer shell 3 and the membrane fibers to enter the membrane fibers and mix with the liquid. This results in excessive gas retention between the outer shell 3 and the membrane filter element 4, increasing the gas pressure, which is detected by the pressure monitoring device 7. Users can promptly detect blockages through the pressure changes monitored by the pressure monitoring device 7, prompting them to address or replace the blockage in a timely manner to ensure effective gas-liquid mixing. Simultaneously, it avoids the risk of the gas-liquid mixing device bursting due to overpressure, effectively improving operational safety and ensuring the continuous production of high-purity mixed liquid. It is also understood that if the pressure inside the outer shell 3 becomes excessive due to factors such as gas source failure, the pressure monitoring device 7 can also detect this promptly.

[0031] In a preferred embodiment, a water quality monitoring device 8 is provided inside the gas-liquid mixing outlet 6.

[0032] In some optional embodiments, the water quality monitoring device 8 is one or more of a conductivity sensor, pH sensor, residual chlorine sensor, and turbidity sensor, used to detect whether the water quality of the mixed solution exceeds the standard and to remind the user and replace it. Furthermore, the impurity content in the liquid is a significant factor leading to membrane fiber blockage. By monitoring the turbidity of the liquid in real time through a turbidity sensor, it is possible to promptly detect whether the impurity content in the liquid exceeds the standard and to promptly remind the user to handle and maintain it, thereby reducing the possibility of membrane fiber blockage due to impurities in the liquid.

[0033] In a preferred embodiment, a concentration monitoring device 9 is installed inside the pressure detection port 5 to detect the gas concentration. If the concentration exceeds the limit, the user is alerted to perform maintenance. The concentration monitoring device 9 is a gas concentration sensor, and the user can select the type of gas concentration sensor according to the gas to be mixed.

[0034] In a preferred embodiment, the pressure monitoring device 7, water quality monitoring device 8, and concentration monitoring device 9 are all electrically connected to a processing module 10, and the processing module 10 is wired to an alert module 11. The processing module 10 is a chip or a microcontroller, and the alert module 11 is a display screen, a speaker, an alarm light, or a mobile terminal. When the processing module 10 detects an anomaly in the data it receives, it sends a signal to the alert module 11 to remind the user to take timely action.

[0035] It is understood that the pressure monitoring device 7, water quality monitoring device 8, and concentration monitoring device 9 can also be electrically connected to the existing gas-liquid mixing control system.

[0036] In a preferred embodiment, the end faces of the membrane filter element 4 at both ends are respectively attached to the inner end faces of the outer shell 3 at both ends, which can effectively ensure that the liquid flows along the path of liquid inlet 1, membrane fiber, and gas-liquid mixing outlet 6, and reduce the possibility of liquid seeping from the gap between the end face of the membrane filter element 4 and the inner end face of the outer shell 3 to the gap between the outer surface of the membrane filter element 4 and the inner surface of the outer shell 3.

[0037] In a preferred embodiment, the inner diameters of both the liquid inlet 1 and the gas-liquid mixing outlet 6 are smaller than the inner diameter of the outer shell 3. On one hand, this restricts the axial freedom of the membrane filter element 4, and combined with the limitation on the inner diameter of the outer shell 3, allows the membrane filter element 4 to be tightly fixed inside the outer shell 3. On the other hand, it allows only a portion of the membrane fibers in the membrane filter element 4 to have their ends directly connected to the liquid inlet 1 or the gas-liquid mixing outlet 6, while the end faces of the remaining membrane fibers are tightly fitted to the inner end face of the outer shell 3. This reduces the possibility of liquid seeping from the gap between the end face of the membrane filter element 4 and the inner end face of the outer shell 3 into the space between the outer surface of the membrane filter element 4 and the inner surface of the outer shell 3.

[0038] In a preferred embodiment, the gas inlet 2 is adjacent to the liquid inlet 1, the pressure detection port 5 is adjacent to the gas-liquid mixing outlet 6, and the flow direction of the gas inside the shell 3 is roughly the same as the flow direction of the liquid, so that the gas and liquid gradually mix as they flow along the axial direction of the shell 3.

[0039] In a preferred embodiment, the outer shell 3, the membrane filter element 4, the liquid inlet 1, and the gas-liquid mixing outlet 6 are coaxial, and the axis of the gas inlet 2 is approximately perpendicular to the axis of the membrane filter element 4. When the gas enters the outer shell 3 through the gas inlet 2, its flow direction is approximately perpendicular to the flow direction of the liquid, thereby enabling it to enter the interior of the membrane fibers more effectively and quickly through the micropores on the sidewalls of the membrane fibers for mixing.

[0040] In a preferred embodiment, the outer casing 3 is made of a transparent material. For example, the outer casing 3 is made of transparent plastic or glass, allowing observation of the internal liquid flow, bubbles, or the color of the membrane filter element 4, thus serving as one means of determining whether the membrane fibers are clogged.

[0041] Working principle of this utility model embodiment:

[0042] In use, the liquid inlet 1 is connected to an external liquid source, and the gas inlet 2 is connected to an external gas source. Liquid enters the membrane fibers of the membrane filter element 4 through the liquid inlet 1 and flows towards the gas-liquid mixing outlet 6. Gas enters sequentially from the gas inlet 2, the inside of the outer shell 3, and the membrane filter element 4, mixing with the liquid. Water vapor and impurities in the gas are trapped on the membrane fiber surface, ultimately forming a high-purity mixture that is discharged from the gas-liquid mixing outlet 6. Furthermore, the pressure monitoring device 7 monitors the gas pressure in real time. When the membrane fibers become clogged, the pressure between the outer shell 3 and the membrane filter element 4, as well as within the pressure detection port 5, increases and is detected by the pressure monitoring device 7. The processing module 10 receives the corresponding signal and controls the alarm module 11 to issue an alarm, reminding the user to address the issue promptly. Therefore, this embodiment of the invention can promptly detect blockages and alert the user, thereby ensuring the gas-liquid mixing effect and the safety of the outer shell 3, and ensuring the continuous production of a high-purity mixture.

This does not affect the essential content of this utility model. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model, without departing from the content of the technical solution of this utility model, still fall within the protection scope of the technical solution of this utility model.
