Description

Technical Field

[0001] The present application relates to the technical field of gas-liquid separators, and particularly relates to an anti-overflow self-cleaning high-efficiency separator. Background Art

[0002] A liquid-gas separator is used to process mainly liquids, for example, to remove entrained air bubbles from a gas-containing mixture to prevent cavitation.

[0003] Currently, the separation method of a conventional liquid-gas separator is single and the separation efficiency is low. The liquid discharge depends only on the pressure in the tank and the pressure of the gas-containing mixture above the liquid seal to squeeze out the liquid. It is easy to cause overflow due to insufficient pressure and untimely liquid discharge.

[0004] Moreover, the conventional liquid-gas separator has no self-cleaning function. It is easy to cause the gas-containing mixture to dry up due to untimely or incomplete cleaning, which in turn affects the separation effect. Summary of the Invention

[0005] The present application discloses an anti-overflow self-cleaning high-efficiency separator for improving the separation efficiency of a liquid-gas separator.

[0006] To achieve the above object, the present application provides the following technical solutions:

[0007] An anti-overflow self-cleaning high-efficiency separator, comprising:

[0008] A main body having an accommodation cavity. The main body is sequentially provided with an exhaust port, a liquid inlet, and a liquid discharge port from top to bottom, and the exhaust port, the liquid inlet, and the liquid discharge port are all communicated with the accommodation cavity;

[0009] A collision separation mechanism disposed in the accommodation cavity and located at the bottom of the liquid inlet. The collision separation mechanism includes a conical collision main body, a funnel-shaped flow guide member, and at least two flow guide vanes. The conical collision main body is installed on the main body. The conical collision main body has an outer surface with a slope from top to bottom. The flow guide vanes are disposed on the outer surface, and adjacent two flow guide vanes form a flow guide channel. The flow guide vanes are in a curved structure. The funnel-shaped flow guide member is installed on the main body and is relatively fixed to the conical collision main body. The funnel-shaped flow guide member has a first opening and a second opening oppositely arranged from top to bottom. The area of the first opening is larger than the area of the second opening. There is a gap between the second opening of the funnel-shaped flow guide member and the conical collision main body, and the orthographic projection of the conical collision main body on the funnel-shaped flow guide member covers the second opening;

[0010] A collection device, the collection device is arranged in the accommodation cavity and located at the bottom of the collision separation mechanism, and the outer edge of the collision separation mechanism is in contact with the inner wall of the body;

[0011] A cutting separation mechanism located at the bottom of the collection device, the cutting separation mechanism is arranged in the accommodation cavity;

[0012] A film separation mechanism, the collision separation mechanism is arranged in the accommodation cavity and located at the bottom of the cutting separation mechanism, the film separation mechanism includes at least one separation plate, and the plane where the separation plate is located forms an angle with the axis of the body, and the angle is an acute angle;

[0013] A self-cleaning spray head, the self-cleaning spray head is arranged above the collision separation mechanism; and / or, the self-cleaning spray head is arranged in the upper middle part of the area where the cutting separation mechanism is located.

[0014] An anti-overflow self-cleaning high-efficiency separator provided in an embodiment of the present application includes a main body. The main body has a receiving cavity. Inside the receiving cavity are a collision separation mechanism, a collection device, a cutting separation mechanism, a film separation mechanism, and a self-cleaning nozzle. An exhaust port is provided at the top of the main body, and a liquid inlet is provided on the side of the main body. A gas-containing mixture enters from the liquid inlet, and then the gas-containing mixture will come into contact with the collision separation mechanism. The gas-containing mixture collides with and is guided by the collision separation mechanism, is scattered, and finally the gas-containing mixture is thrown out, thus completing the first liquid-gas separation. The thrown gas-containing mixture is evenly sprinkled on the inner wall of the main body and dispersed, performing the second liquid-gas separation. Under the action of gravity, since the outer edge of the collection device contacts the inner wall of the main body, the gas-containing mixture is effectively collected. The gas-containing mixture collected by the collection device undergoes a third liquid-gas separation through the cutting separation mechanism. The gas-containing mixture continues to flow downward along the separation plate of the film separation mechanism under the action of gravity, forming an extremely thin sheet-like liquid film, and the gas in the gas-containing mixture escapes from the sheet-like liquid film, thus performing the fourth liquid-gas separation. Through the four separations of the gas-containing mixture, for example, if the gas-containing mixture is gas-containing mud, especially the collision separation mechanism, through processes such as collision, diversion, sprinkling, and dispersion of the gas-containing mixture, the gas in the mud is separated more thoroughly and the mud film is more uniform. While enhancing the separation effect, it also provides a guarantee for subsequent efficient separation. Specifically, the collision separation mechanism includes a conical collision body, a funnel-shaped guide member, and at least two guide vanes. The combined design of the conical collision body and the funnel-shaped guide member can effectively guide the flow of gas-containing mud and achieve preliminary liquid-gas separation through the flow guide channels formed by the guide vanes. The slope design of the conical collision body helps to disperse and collide the gas-containing mud, making it easier for the gas in the gas-containing mud to escape. The cutting separation mechanism located at the bottom of the collection device can further separate the gas in the gas-containing mud, making the bubbles in the gas-containing mud smaller through cutting, and thus easier to separate. Here, for the film separation mechanism, the design in which the separation plate forms an acute angle with the axis of the main body can increase the contact area between the gas-containing mud and the separation plate and extend the residence time of the gas-containing mud during the separation process, thereby improving the separation efficiency. In addition, the self-cleaning nozzle is arranged above the collision separation mechanism; and / or, the self-cleaning nozzle is arranged in the upper middle part of the area where the cutting separation mechanism is located. Such a design can spray and wash the inside of the separator regularly or as needed. This design can effectively prevent impurities or contaminants in the liquid from accumulating inside the separator, avoid problems such as blockage and reduction of separation efficiency, and extend the service life of the equipment. It can be understood that an anti-overflow self-cleaning high-efficiency separator provided in the present application has at least the following effects: From the liquid inlet to the liquid outlet, the entire separation process is completed inside the receiving cavity, with a compact structure and space saving. At the same time, the components are relatively fixed and cooperate with each other, ensuring the high efficiency and stability of the separation process.The multi-stage separation setting method, which sequentially performs collision separation, cutting separation, and membrane separation, forms a multi-stage separation structure that can gradually improve the separation effect and ensure a greatly reduced gas content and high purity in the finally discharged mud. Moreover, it has adjustability. By adjusting parameters such as the bending degree of the flow guiding vane and the angle of the separation plate, it can be optimized according to the characteristics of different gas-containing mixtures, improving the adaptability and flexibility of the separator. The design of the self-cleaning nozzle reduces the frequency of manual cleaning, lowers the maintenance cost and labor intensity. And an automatic control device for controlling the self-cleaning nozzle is also provided outside the main body, which facilitates controlling the self-cleaning nozzle to automatically clean the inner wall of the accommodation cavity of the main body. Multiple nozzles are set at key positions for more thorough cleaning.

[0015] Optionally, there are multiple flow guiding vanes, and multiple flow guiding channels are formed by the multiple flow guiding vanes. At least two of the multiple flow guiding channels have the same shape. The width of the flow guiding channel gradually increases from the center of the conical collision body to the edge.

The first cutting component includes multiple first cutting blades arranged along the axis direction, and the second cutting component includes multiple second cutting blades arranged along the axis direction. The number of the multiple first cutting blades is greater than the number of the multiple second cutting blades; the shapes of the multiple first cutting blades are circular rings, and the shapes of the multiple second cutting blades are circular rings; from top to bottom, the outer diameters of the multiple first cutting blades gradually decrease, and from top to bottom, the outer diameters of the multiple second cutting blades gradually increase.

[0020] Optionally, for the multiple first cutting blades, the outer diameter of the first cutting blade facing the second cutting component is the first outer diameter d1, and for the multiple second cutting blades, the outer diameter of the second cutting blade facing the first cutting component is the second outer diameter d2.

[0021] Optionally, along the axis direction, the spacing distance h1 between adjacent two of the multiple first cutting blades is the same, and the spacing distance h2 between adjacent two of the multiple second cutting blades is the same, and h1 = h2.

[0042] As Figures 1 to 12 shown, the embodiments of the present application provide an anti-overflow self-cleaning high-efficiency separator, comprising:

[0043] A body 1, the body 1 having a receiving cavity 11. The body 1 is successively provided with an exhaust port 12, a liquid inlet 13, and a liquid discharge port 14 from top to bottom, and the exhaust port 12, the liquid inlet 13, and the liquid discharge port 14 are all in communication with the receiving cavity 11;

[0044] A collision separation mechanism 2, the collision separation mechanism 2 being arranged in the receiving cavity 11 and located at the bottom of the liquid inlet 13; the collision separation mechanism 2 includes a conical collision body 21, a funnel-shaped flow guiding member 22, and at least two flow guiding vanes 23. The conical collision body 21 is installed on the body 1, the conical collision body 21 having an outer surface with a slope from top to bottom. The flow guiding vanes 23 are arranged on the outer surface, and adjacent two flow guiding vanes 23 form a flow guiding channel. The flow guiding vanes 23 are of a curved structure;

[0045] The funnel-shaped flow guiding member 22 is installed on the body 1 and is relatively fixed to the conical collision body 21. The funnel-shaped flow guiding member 22 has a first opening 221 and a second opening 222 arranged opposite to each other from top to bottom. The area of the first opening 221 is larger than the area of the second opening 222. There is a gap between the second opening 222 of the funnel-shaped flow guiding member 22 and the conical collision body 21, and the orthographic projection of the conical collision body 21 on the funnel-shaped flow guiding member 22 covers the second opening 222;

[0046] A collection device 3, the collection device 3 being arranged in the receiving cavity 11 and located at the bottom of the collision separation mechanism 2, and the outer edge of the collision separation mechanism 2 being in contact with the inner wall of the body 1;

[0047] A cutting separation mechanism 4 located at the bottom of the collection device 3, the cutting separation mechanism 4 being arranged in the receiving cavity 11;

[0048] A film separation mechanism 5, the collision separation mechanism 2 being arranged in the receiving cavity 11 and located at the bottom of the cutting separation mechanism 4. The film separation mechanism 5 includes at least one separation plate 51, and the plane where the separation plate 51 is located forms an acute angle with the axis of the body 1;

[0049] The self-cleaning nozzle 6 is arranged above the collision separation mechanism 2; and / or, the self-cleaning nozzle 6 is arranged in the upper middle part of the area where the cutting separation mechanism 4 is located.

[0050] It should be noted that an anti-overflow self-cleaning high-efficiency separator provided in an embodiment of the present application includes a main body 1. The main body 1 has a receiving cavity 11. A collision separation mechanism 2, a collection device 3, a cutting separation mechanism 4, a film separation mechanism 5, and a self-cleaning nozzle 6 are all located inside the receiving cavity 11. An exhaust port 12 is provided at the top of the main body 1, and a liquid inlet 13 is provided on the side of the main body 1. A gas-containing mixture enters from the liquid inlet 13, and then the gas-containing mixture will come into contact with the collision separation mechanism 2. The gas-containing mixture collides and diverts with the collision separation mechanism 2, is scattered, and until the gas-containing mixture is thrown out. Thus, the first liquid-gas separation is completed. The thrown gas-containing mixture is evenly sprinkled on the inner wall of the main body 1 and scattered, performing the second liquid-gas separation. Due to the outer edge of the collection device 3 contacting the inner wall of the main body 1 under the action of gravity, the gas-containing mixture is effectively collected. After being collected by the collection device 3, the gas-containing mixture passes through the cutting separation mechanism 4 to perform the third liquid-gas separation on the gas-containing mixture. The gas-containing mixture continues to flow downward along the separation plate 51 of the film separation mechanism 5 under the action of gravity, forming an extremely thin sheet-like liquid film. The gas in the gas-containing mixture escapes from the sheet-like liquid film. Thus, the fourth liquid-gas separation has been performed. Through the four separations of the gas-containing mixture, for example, the gas-containing mixture is gas-containing mud. Especially for the collision separation mechanism 2, through processes such as collision, diversion, sprinkling, and scattering of the gas-containing mixture, the gas in the mud is separated more thoroughly and the mud film is more uniform. While enhancing the separation effect, it also provides a guarantee for subsequent high-efficiency separation. Specifically, the collision separation mechanism 2 includes a conical collision body 21, a funnel diversion member 22, and at least two diversion vanes 23. The combined design of the conical collision body 21 and the funnel diversion member 22 can effectively guide the flow of gas-containing mud and achieve preliminary liquid-gas separation through the diversion channels formed by the diversion vanes 23. The slope design of the conical collision body 21 helps to disperse and collide the gas-containing mud, making it easier for the gas in the gas-containing mud to escape. The cutting separation mechanism 4 located at the bottom of the collection device 3 can further separate the gas in the gas-containing mud, making the bubbles in the gas-containing mud smaller through the cutting action, and thus making it easier to separate. Here, for the film separation mechanism 5, the design that the separation plate 51 forms an acute angle with the axis of the main body 1 can increase the contact area between the gas-containing mud and the separation plate 51 and extend the residence time of the gas-containing mud during the separation process, thereby improving the separation efficiency. In addition, the self-cleaning nozzle 6 is provided above the collision separation mechanism 2; and / or, the self-cleaning nozzle 6 is provided in the upper middle part of the area where the cutting separation mechanism 4 is located. Such a design can spray and wash the inside of the separator regularly or as needed. This design can effectively prevent impurities or pollutants in the liquid from accumulating inside the separator, avoid problems such as blockage and reduction of separation efficiency, and extend the service life of the equipment.It can be understood that an anti-overflow self-cleaning high-efficiency separator provided by the present application has at least the following effects: from the liquid inlet 13 to the liquid outlet 14, the entire separation process is completed within the accommodation chamber 11, with a compact structure and space saving. At the same time, the components are relatively fixed and cooperate with each other, ensuring the high efficiency and stability of the separation process. The multi-stage separation setting method, through collision separation, cutting separation, and membrane separation in sequence, forms a multi-stage separation structure, which can gradually improve the separation effect and ensure that the gas content in the finally discharged slurry is greatly reduced in purity. And it has adjustability. By adjusting parameters such as the bending degree of the guide vane 23 and the angle of the separation plate 51, it can be optimized according to the characteristics of different gas-containing mixtures, improving the adaptability and flexibility of the separator. The design of the self-cleaning nozzle 6 reduces the frequency of manual cleaning, lowers the maintenance cost and labor intensity, and an automatic control device for controlling the self-cleaning nozzle 6 is also provided outside the main body 1, facilitating the control of the self-cleaning nozzle 6 to automatically clean the inner wall of the accommodation chamber 11 of the main body 1, and multiple nozzles are arranged at key positions for more thorough cleaning.

[0051] Continue to refer to Figure 1 , in Figure 1 , an exhaust port 12, a liquid inlet 13, a safety valve interface 15, a manhole 16, and a liquid outlet 14 communicating with the accommodation chamber 11 of the main body 1 are sequentially arranged from top to bottom.

[0052] Here, the area of the first opening 221 on the funnel guide member 22 is larger than that of the second opening 222, that is to say, the funnel guide member 22 is a horn-shaped structure. Such a design helps to collect and gather as much gas-containing mixture as possible, so that it can fully contact the conical collision body 21 and the guide vane 23 in the collision separation mechanism 2.

[0053] In some specific embodiments, the plane where the separation plate 51 is located forms an angle with the axis of the main body 1, and this angle is an acute angle, and the degree of this angle is 45° - 80°. For example, this angle can be 45°, 50°, 55°, 60°, 65°, 70°, 75°, or 80°.

[0054] In some specific embodiments, there are multiple flow guiding vanes 23. The multiple flow guiding vanes 23 form multiple flow guiding channels, and at least two of the multiple flow guiding channels have the same shape. The width of the flow guiding channels gradually increases from the center of the conical collision body 21 to the edge. The multiple flow guiding vanes 23 form multiple flow guiding channels. This multi-channel design can effectively increase the contact area between the gas-containing mixture and the flow guiding vanes 23, so that the gas-containing mixture is more evenly dispersed when entering the collision separation mechanism 2. Compared with a single channel, the multi-channel can significantly improve the dispersion efficiency of the liquid, thereby better achieving the effect of liquid-gas separation. The flow guiding channels with the same shape ensure the consistency of the flow state of the liquid in different channels. This consistency helps to form a stable flow pattern, avoid uneven liquid distribution caused by differences in channel shapes, and further improve the separation efficiency.

[0055] The width of the flow guiding channels gradually increases from the center of the conical collision body 21 to the edge. This design of width change can guide the gas-containing mixture to gradually diffuse during the flow process, so that the gas-containing mixture can be more evenly distributed when entering the collision separation area. This design is similar to the diffusion effect of a flared opening, which can effectively reduce the accumulation of liquid in the central area, avoid excessive local pressure, and thus improve the performance of the entire separator. By reasonably designing the width change of the flow guiding channels, the turbulence and resistance of the liquid during the flow process can be reduced. This design helps to reduce the energy loss of the liquid flow, improve the operating efficiency of the separator, and at the same time reduce the liquid-gas mixing caused by turbulence, further enhancing the separation effect. Moreover, this multi-channel design and the flow guiding channels with width change can adapt to different liquid flow rates; there are flow guiding channels with larger widths and flow guiding channels with narrower widths among the multiple flow guiding channels. For example, when the flow rate is small, the liquid can flow through the narrower flow guiding channels in the center; when the flow rate is large, the liquid can be evenly distributed in multiple channels, avoiding a decrease in the separation effect caused by excessive flow rate.

[0056] In some specific embodiments, the surface of the flow guiding vane 23 facing the flow guiding channel is not perpendicular to the outer surface of the conical collision body 21.

[0057] Specifically, the collecting device 3 has a third opening 31 and a fourth opening 32 that are oppositely arranged from top to bottom; the area of the first opening 221 of the conical collision body 21 is the same as the area of the fourth opening 32 of the collecting device 3. Moreover, the area of the third opening 31 is the same as the cross-sectional area of the vertical axis of the accommodation cavity 11 of the main body 1. Due to the precise matching and relative arrangement of the areas of the first opening 221 and the fourth opening 32, the liquid can reduce turbulence and resistance during the flow process, and reduce energy loss. This design not only improves the separation efficiency, but also reduces the liquid-gas mixing caused by turbulence, further enhancing the separation effect.

[0058] It can be understood that the cutting and separating mechanism 4 includes a first cutting assembly 41 and a second cutting assembly 42 which are oppositely arranged from top to bottom. The first cutting assembly 41 includes a plurality of first cutting blades 411 arranged along the axial direction, and the second cutting assembly 42 includes a plurality of second cutting blades 421 arranged along the axial direction. The number of the plurality of first cutting blades 411 is greater than the number of the plurality of second cutting blades 421. This multi-layer cutting design can achieve multiple cuts on the bubbles or impurities in the liquid, significantly improve the cutting efficiency, and ensure that the bubbles or impurities in the liquid are fully separated. The shapes of the plurality of first cutting blades 411 are circular rings, and the shapes of the plurality of second cutting blades 421 are circular rings. This circular ring shape design enables the cutting blades to be evenly distributed in the liquid flow, ensuring uniform distribution of the cutting force and effectively improving the separation of gas from the gas-containing mud. And the outer diameters of the plurality of first cutting blades 411 gradually decrease from top to bottom, and the outer diameters of the plurality of second cutting blades 421 gradually increase from top to bottom. This size change design can guide the liquid to form a stable flow path during the cutting process, reducing turbulence and resistance. The gradually decreasing outer diameter of the first cutting blade 411 enables the bubbles in the liquid to first pass through the cutting blade with a larger diameter for preliminary cutting when entering the cutting area, and then gradually pass through the cutting blades with smaller diameters for fine cutting. This progressive cutting method can more effectively separate the bubbles in the liquid.

[0059] For example, among the plurality of first cutting blades 411, the outer diameter of the first cutting blade 411 facing the second cutting assembly 42 is the first outer diameter d1, and among the plurality of second cutting blades 421, the outer diameter of the second cutting blade 421 facing the first cutting assembly 41 is the second outer diameter d2, and the first outer diameter d1 is greater than the second outer diameter d2.

[0060] For example, along the axial direction, the spacing distance h1 between two adjacent first cutting blades 411 among the plurality of first cutting blades 411 is the same, and the spacing distance h2 between two adjacent second cutting blades 421 among the plurality of second cutting blades 421 is the same, and h1 = h2. Such an arrangement method enables the separation of gas in the gas-containing mixture to be more thorough and complete.

[0061] Reference Figure 10 , the first cutting assembly 41 further includes a first support frame 412. The first support frame 412 is arranged in the inner diameter of the first cutting blade 411. The first support frame 412 includes at least three first support bars 4121. For example, there are four first support bars 4121, and the ends of the first support bars 4121 are connected to form a first conical structure. Of course, in order to facilitate the installation of the first cutting blade 411 and the first support frame 412 in the first cutting assembly 41, a first connecting frame 413 with a cross shape is also provided here.

[0062] The second cutting assembly 42 further includes a second support frame 422. The second support frame 422 is disposed within the inner diameter of the second cutting blade 421. The second support frame 422 includes at least three second support bars 4221, and the ends of the second support bars 4221 are connected to form a second conical structure. For example, there are four second support bars 4221, and the ends of the second support bars 4221 are connected to form a second conical structure. Of course, in order to facilitate the installation of the second cutting blade 421 and the second support frame 422 in the second cutting assembly 42, a second connecting frame 423 with a cross shape is also provided here. In order to relatively fix the first cutting assembly 41 and the second cutting assembly 42, the top end of the first conical structure is connected to the top end of the second conical structure.

[0063] To further improve the separation efficiency, the film separation mechanism 5 includes: two layers of separation plates 51, neither of the two layers of separation plates 51 is perpendicular to the axis, and the included angle between the two layers of separation plates 51 is an acute angle.

[0064] The anti-overflow self-cleaning type high-efficiency separator provided by the embodiment of the present application further includes a screw pump and a liquid level control device. The screw pump is communicated with the liquid discharge port 14, and the liquid level control device is disposed within the main body 1. That is to say, a bypass is added to the horizontal section at the bottom of the liquid discharge pipe communicated with the liquid discharge port 14. A screw pump matching the required liquid discharge flow is installed on the bypass pipe, and a liquid level control device is installed in the cylinder body. During normal liquid discharge, the main pipeline is used. When the liquid discharge volume is insufficient, the liquid level in the cylinder body rises and triggers the control switch, and the screw pump on the bypass pipe is started for forced discharge to lower the liquid level. When the liquid level drops to a safe position, the screw pump will be stopped through the control switch. The problem of overflowing is solved by the screw pump, ensuring the separation effect.

[0065] Obviously, those skilled in the art can make various modifications and variations to the embodiments of the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
