Description

Technical Field

[0001] This application relates to the technical field of separation devices, and more particularly to a gas-water separation device. Background Technology

[0002] Gas-liquid separators play a vital role in many fields such as industrial production, energy utilization, and environmental treatment. They can effectively separate gas and liquid, ensuring the normal operation of subsequent processes or equipment.

[0003] Existing gas-liquid separators are generally used in relatively fixed ways, mainly in two conventional modes: downward installation and upward installation. When installed downwards, the device's specific structural design guides the gas and liquid along predetermined paths, allowing the gas to be discharged smoothly, while the liquid is collected and discharged through corresponding channels, thus achieving gas-liquid separation. Similarly, in the upward installation mode, the device, based on specific internal structures and fluid dynamics principles, allows the gas-liquid mixture to complete the separation process within the device, ensuring that the gas is discharged from the top, while the liquid is collected and processed at the bottom.

[0004] However, the relatively fixed usage of existing gas-liquid separators has significant limitations. Once the upward installation is reversed, changing its original pre-designed orientation, the internal hydrodynamic characteristics of the device change significantly. Because the device was not optimized for this reverse installation, there is a lack of effective guidance and control mechanisms to prevent liquid from escaping from the upper vent when there is excessive water inside. In this case, excess water will overflow directly from the upper vent, preventing gas and liquid from separating along the normal design path, thus causing the gas-liquid separator to fail to achieve the expected separation effect. This not only affects the normal operation of subsequent processes and reduces production efficiency but may also damage the equipment, increase maintenance costs, and create safety hazards. Utility Model Content

[0005] The purpose of this application is to provide a gas-water separation device. By setting a step and opening a through groove on the step, when the original upward installation method is switched to downward installation, the water volume inside the separation chamber is larger. When the float rises to the second channel opening, the gas can be discharged through the through groove, but the liquid will not be discharged. When installed upward, the through groove can also ensure that the liquid in the separation chamber is completely discharged.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] On the one hand, a gas-water separation device is provided, including: a main body and a float. A separation cavity is formed inside the main body, and the float is movably installed in the separation cavity. One end of the main body is provided with two first channel openings that communicate with the separation cavity, and the opposite end is provided with a second channel opening that communicates with the separation cavity. The bottom of the separation cavity is provided with a step corresponding to the position of the first channel opening, and one of the steps is provided with a through groove that communicates its inner side and outer side.

[0008] Furthermore, the float has a top post protruding from one end opposite the second channel opening, and a sealing sleeve is fitted on the top post, which can abut against and seal the second channel opening.

[0009] Furthermore, venting grooves are symmetrically arranged on both sides of the top column.

[0010] Furthermore, the main body includes a housing and an end cap, the end cap being detachably mounted on the end of the housing, the first channel opening being located at the bottom of the housing, and the second channel opening being located at the top of the end cap.

[0011] Furthermore, a locking structure is provided at the connection between the outer shell and the end cap.

[0012] Furthermore, the locking structure includes a first locking buckle disposed on the outer wall of the housing and a second locking buckle disposed on the inner wall of the end cap, wherein the first locking buckle and the second locking buckle cooperate to lock together.

[0013] Furthermore, the locking structure also includes an anti-disengagement buckle disposed on the outer edge of the housing and an anti-disengagement groove disposed on the inner edge of the end cap, wherein the anti-disengagement buckle can be embedded in the anti-disengagement groove.

[0014] Furthermore, a sealing element is provided at the connection between the outer shell and the end cap.

[0015] Furthermore, a fixing seat is provided on the outer wall surface of the main body; and / or multiple ribs are provided at intervals on the outer peripheral surface of the float.

[0016] Furthermore, one end of the main body is provided with a first connecting post corresponding to the first channel opening, and the other end is provided with a second connecting post corresponding to the second channel opening. Both the first connecting post and the second connecting post form an inlet / outlet channel inside.

[0017] The beneficial effects of this application are as follows: By setting steps and creating through-grooves on the steps, effective gas-liquid separation is achieved under different installation methods. When installed upwards, the gas-liquid mixture enters the separation chamber through the first channel opening corresponding to one of the steps without through-grooves. The float divides the separation chamber into upper and lower parts. Under gravity, the liquid exits through the first channel opening corresponding to the step with through-grooves (as the liquid outlet), while the gas exits through the second channel opening at the opposite end (as the gas outlet). The through-grooves do not affect normal gas-liquid separation and discharge under this installation method. When installed downwards, the gas-liquid mixture enters through the first channel opening corresponding to another step without through-grooves. When the water volume inside the separation chamber is large and the float rises to near the second channel opening, the first channel opening corresponding to the step with through-grooves becomes the gas outlet. Gas can exit through the through-grooves, preventing accumulation in the separation chamber. The liquid, due to the float's obstruction and its own gravity, exits through the second channel opening at the opposite end (as the liquid outlet) and will not exit through the first channel opening with through-grooves. The device has significant advantages. On the one hand, it breaks the limitations of the fixed usage of existing gas-liquid separators, allowing for flexible upward or downward installation to adapt to different installation environments and space requirements, thus improving versatility and applicability. On the other hand, it ensures reliable gas-liquid separation under different installation methods, optimizes the liquid discharge function, and has a simple structure that is easy to implement and apply in actual production, reducing production costs and modification difficulties.

[0027] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] like Figures 1 to 7As shown, this embodiment provides a gas-water separation device, including: a main body 1 and a float 2. The main body 1 has a separation cavity 108 inside, and the float 2 is movably installed in the separation cavity 108. One end of the main body 1 is provided with two first channel openings 109 communicating with the separation cavity 108, and the opposite end is provided with a second channel opening 110 communicating with the separation cavity 108. The bottom of the separation cavity 108 is provided with a step 106 corresponding to the position of the first channel opening 109, and one of the steps 106 is provided with a through groove 107 communicating with its inner and outer sides.

[0031] Based on the above solutions, such as Figure 6 As shown, during upward installation, the gas-liquid mixture enters the separation chamber 108 through the first channel opening 109 corresponding to one of the steps 106 without the through groove 107. Due to the presence of the float 2, it automatically rises or sinks according to the height of the liquid in the separation chamber 108. As the gas-liquid mixture continuously enters, the liquid gradually accumulates at the bottom of the separation chamber 108, while the gas rises to the upper space. The float 2 divides the separation chamber 108 into upper and lower parts, with the lower part being the liquid and the upper part being the gas. The first channel opening 109 corresponding to the step 106 with the through groove 107 serves as the liquid outlet, through which the liquid in the separation chamber 108 is discharged under its own gravity. The separated gas is discharged through the second channel opening 110 at the opposite end. During this process, the presence of the through groove 107 does not affect the normal gas-liquid separation and discharge function during upward installation; it mainly prepares for the special working conditions during subsequent downward installation.

[0032] like Figure 7 As shown, when installed downwards, the gas-liquid mixture enters the separation chamber 108 through the first channel opening 109 corresponding to the step 106 without the through groove 107. Similarly, the float 2 adjusts its position according to the liquid level in the separation chamber 108. When the water volume inside the separation chamber 108 is large, the float 2 rises to near the second channel opening 110. At this time, the first channel opening 109 corresponding to the step 106 with the through groove 107 serves as the gas outlet. Since the through groove 107 connects the inside and outside of the step 106, when the float 2 rises to a certain position, the gas can be discharged through the through groove 107 from the first channel opening 109, preventing gas accumulation in the separation chamber 108. The liquid in the separation chamber 108 is discharged through the second channel opening 110 at the opposite end. The design of the through groove 107 allows gas to still find a discharge path even when the float 2 rises and blocks most of the space in the second channel opening 110, while the liquid will not be discharged from the first channel opening 109 with the through groove 107 due to the obstruction of the float 2 and its own gravity, thus achieving gas-liquid separation.

[0033] Existing gas-liquid separators have relatively fixed usage methods, but the gas-liquid separator of this application breaks this limitation, allowing for both upward and downward installation. This flexibility enables the device to adapt to different installation environments and space requirements, improving its versatility and applicability. When installed upwards, the device operates normally according to the conventional gas-liquid separation principle, ensuring that liquid is discharged from the designated liquid outlet and gas is discharged from the gas outlet, achieving effective gas-liquid separation. Furthermore, the presence of the through-channel 107 does not affect the normal discharge of liquid from the first channel opening 109 corresponding to the step 106 with the through-channel 107, ensuring smooth liquid discharge. When installed downwards, by setting the step 106 and the through-channel 107, when the water volume inside the separation chamber 108 is large and the float 2 rises, gas can be discharged through the through-channel 107 from the specific gas outlet, while liquid will not be discharged from this outlet. This avoids the problem of gas-liquid separation failure due to changes in installation method, ensuring reliable gas-liquid separation under different installation conditions. Moreover, the through channel 107 provides an additional discharge path for gas without affecting the discharge of liquid from the second channel port 110, further optimizing the liquid discharge function of the device under different installation methods and improving the working efficiency and stability of the device.

[0034] In addition, the technical solution of this application only requires opening a through groove 107 on the step 106 inside the main body 1. The structure is relatively simple and does not require large-scale modification of the existing gas-water separation device. It is easy to implement and apply in actual production, reducing production costs and modification difficulty.

[0035] Preferably, the float 2 has a top post 201 protruding from one end opposite the second channel opening 110. A sealing sleeve 3 is fitted onto the top post 201, and the sealing sleeve 3 can abut and seal against the second channel opening 110. Venting grooves 202 are symmetrically arranged on both sides of the top post 201. The venting grooves 202 prevent air from accumulating inside the sealing sleeve 3 during installation of the top post 201 and the sealing sleeve 3, thus preventing proper installation. In this solution, on the one hand, it ensures that the sealing sleeve 3 on the top post 201 of the float 2 can be properly installed, ensuring a good seal between the sealing sleeve 3 and the second channel opening 110, effectively preventing gas or liquid leakage from the seal, and improving the gas-water separation effect and sealing performance of the device. On the other hand, the venting grooves 202 solve the problem of air accumulating during the installation of the sealing sleeve 3, avoiding problems such as low production efficiency and unstable installation quality caused by installation difficulties, and improving the production and assembly efficiency and quality of the device.

[0036] It is important to note that the function of the sealing sleeve 3 differs depending on the installation mode. When facing upwards, the float 2 rises to the top, blocking the second channel opening 110 (i.e., the air outlet), creating pressure inside the separation chamber 108, which pushes the float 2 downwards, accelerating liquid discharge. When facing downwards, the float 2 reaches the bottom, blocking the second channel opening 110 (i.e., the water outlet), preventing gas from escaping through the water outlet.

[0037] In some embodiments, the main body 1 includes a housing 101 and an end cap 102. The end cap 102 is detachably mounted on the end of the housing 101. A first channel opening 109 is located at the bottom of the housing 101, and a second channel opening 110 is located at the top of the end cap 102. During device assembly, the end cap 102 can be easily removed and installed from the end of the housing 101. When maintenance, repair, or replacement of components is required inside the device, the end cap 102 can be removed from the housing 101 to directly access the interior of the separation chamber 108, facilitating related operations. For example, if the float 2 is damaged or impurities need to be cleaned from the separation chamber 108, this detachable structure greatly simplifies the operation process and improves maintenance efficiency. During normal use, the end cap 102 is tightly mounted on the end of the housing 101, together with the housing 101 forming a complete separation chamber 108, ensuring that the gas-water separation process proceeds normally within a closed space.

[0038] Furthermore, a locking structure is provided at the connection between the outer shell 101 and the end cap 102. The locking structure includes a first locking buckle 5 disposed on the outer wall of the outer shell 101 and a second locking buckle 6 disposed on the inner wall of the end cap 102. The first locking buckle 5 and the second locking buckle 6 cooperate to lock together. In some embodiments, the main body 1 is detachably assembled from the outer shell 101 and the end cap 102. The first channel opening 109 is located at the bottom of the outer shell 101, and the second channel opening 110 is located at the top of the end cap 102. A locking structure is provided at the connection between the outer shell 101 and the end cap 102. The locking structure includes a first locking buckle 5 disposed on the outer wall of the outer shell 101 and a second locking buckle 6 disposed on the inner wall of the end cap 102. The first locking buckle 5 and the second locking buckle 6 cooperate to lock together. Its working principle is as follows: During device assembly, the end cap 102 is aligned with the end of the outer shell 101 for installation. As the end cap 102 gradually approaches and fits against the outer shell 101, the first locking buckle 5 on the outer wall of the outer shell 101 contacts and engages with the second locking buckle 6 on the inner wall of the end cap 102. This engagement allows the end cap 102 to be securely installed on the outer shell 101, forming a complete and sealed separation chamber 108, ensuring that the gas-water separation process takes place in a closed and stable environment. When maintenance or repair of the device is required, the engagement of the first locking buckle 5 and the second locking buckle 6 can be released through a specific operation, allowing the end cap 102 to be easily removed from the outer shell 101 for cleaning, component replacement, and other operations inside the separation chamber 108.

[0039] Furthermore, the locking structure also includes an anti-disengagement buckle 7 located on the outer edge of the housing 101 and an anti-disengagement groove 8 located on the inner edge of the end cap 102. The anti-disengagement buckle 7 can be embedded in the anti-disengagement groove 8. When the end cap 102 is installed on the end of the housing 101, as the end cap 102 gradually approaches the housing 101, the anti-disengagement buckle 7 located on the outer edge of the housing 101 will naturally embed into the anti-disengagement groove 8 on the inner edge of the end cap 102. After the first locking buckle 5 and the second locking buckle 6 have completed their locking, and the end cap 102 and the housing 101 are initially fixed to form a complete separation cavity 108, the anti-disengagement buckle 7 embedded in the anti-disengagement groove 8 provides additional fixing and anti-disengagement functions. In daily use or when subjected to external forces, the interlocking structure of the anti-disengagement buckle 7 and the anti-disengagement groove 8 can effectively prevent the end cap 102 from accidentally falling off the housing 101 due to vibration, impact, or other factors, further ensuring the stability and reliability of the device. When the end cover 102 needs to be removed for maintenance, the locking state of the first locking buckle 5 and the second locking buckle 6 must be released first, and the anti-disengagement buckle 7 must be disengaged from the anti-disengagement groove 8 before the end cover 102 can be smoothly removed from the outer shell 101.

[0040] In this device, the outer casing 101 and the end cap 102 are connected by threads, and a seal 4 is provided at the connection. During device assembly, the threaded portion of the end cap 102 is screwed onto the threaded portion of the outer casing 101. As the threads are tightened, the end cap 102 gradually approaches the outer casing 101 and eventually fits tightly against it. During this process, the seal 4 at the connection is subjected to the compressive force between the end cap 102 and the outer casing 101, causing it to elastically deform and fill the tiny gap at the threaded connection between the end cap 102 and the outer casing 101. This elastic deformation allows the seal 4 to fit tightly against the connection, forming an effective sealing barrier to prevent gas or liquid from leaking from the connection. During normal operation of the device, the seal 4 continues to function, ensuring that the gas-liquid separation process within the separation chamber 108 is not disturbed by external factors, thus guaranteeing the airtightness and stability of the device. When it is necessary to remove the end cover 102 for maintenance or repair, simply rotate the end cover 102 in the opposite direction to loosen the threads, and the end cover 102 will separate from the outer shell 101. At this time, the seal 4 will return to its original state and will not hinder the disassembly process.

[0041] It is worth mentioning that the outer wall of the main body 1 of the device is provided with a fixing seat 103, which can be fixed to the bracket with screws; at the same time, multiple ribs 203 are provided at intervals on the outer circumference of the float 2. Regarding the fixing seat 103, during device installation, the fixing seat 103 of the main body 1 is aligned with the pre-set bracket, and then screws are passed through the mounting holes on the fixing seat 103 and tightened onto the bracket, thereby firmly fixing the main body 1 to the bracket. In this way, the device can be stably installed in the required working position, and will not easily shake or shift due to external factors, ensuring the stability of the device operation. Regarding the ribs 203 on the outer circumference of the float 2, as the float 2 floats up and down with the liquid level change in the separation chamber 108, the ribs 203 will contact the inner wall of the separation chamber 108. When the float 2 is subjected to water flow impact or other external forces, the ribs 203 can act as a limit, preventing the float 2 from excessively tilting or deviating from its normal position. The presence of the rib 203 allows the float 2 to maintain a suitable water-holding space within the separation chamber 108, ensuring that the float 2 can perform its function of air-water separation normally and preventing air-water separation failure due to abnormal position of the float 2.

[0042] Optionally, one end of the main body 1 is provided with a first connecting post 104 corresponding to the first channel port 109, and the other end is provided with a second connecting post 105 corresponding to the second channel port 110. Both the first connecting post 104 and the second connecting post 105 have inlet and outlet channels inside. During gas-liquid separation, the gas-liquid mixture flows into the separation chamber 108 from the first channel port 109 through the inlet and outlet channels inside the first connecting post 104 via a connector or hose connected to it. After separation, the gas passes through the second channel port 110 and then through the inlet and outlet channels inside the second connecting post 105, exiting from the connector or hose connected to it; while the separated liquid exits from other corresponding outlets. When connection to other equipment or pipelines is required, simply connect suitable connectors or hoses to the first connecting post 104 and the second connecting post 105 respectively to achieve the input of the gas-liquid mixture and the output of the separated gas and liquid, making operation simple and convenient.

[0043] Specifically, the second channel opening 110 of the end cap 102 is conical on the side near the separation chamber 108. This design reduces the contact area of ​​the sealing surface, preventing excessive contact and potential leakage. When the sealing sleeve 3 abuts against the second channel opening 110 under the push of the top post 201, the conical design results in a smaller annular contact area between the sealing sleeve 3 and the second channel opening 110. Compared to flat or large-area contact, this smaller contact area reduces the difficulty in proper contact caused by machining errors, installation deviations, or surface unevenness. Because of the small contact area, the sealing sleeve 3 can more easily and tightly fit against the conical surface of the second channel opening 110 when subjected to slight external force or its own elastic deformation, forming an effective seal and reducing potential leakage due to an excessively large contact area.
