DETAILED DESCRIPTION

[0022] The present invention provides a gas-liquid separator, which provides a plurality of gas-liquid separation areas in the gas-liquid separator to separate the gas multiple times, thereby forming redundancy of the separation process and ensuring the amount of liquid droplets removed from the gas.

[0023] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] As shown in the figure, the present invention provides a gas-liquid separator, including an air inlet 71 and an exhaust port 72. The gas carrying droplets can enter the gas-liquid separator from the air inlet 71 and flow out from the exhaust port 72. The gas-liquid separator also includes a cylinder 9, in which are arranged a centrifugal chamber 1, a liquid collecting chamber 8, a filling chamber 4 and a defoaming chamber 5 separated from each other; in an embodiment of the present application, the centrifugal chamber 1, the liquid collecting chamber 8, the filling chamber 4 and the defoaming chamber 5 are arranged and connected in sequence in the direction of gas flow; the air inlet 71 is connected to the centrifugal chamber 1, and the exhaust port 72 is connected to the defoaming chamber 5. After the gas enters the cylinder 9 from the air inlet 71, it will first be separated for the first time in the centrifugal chamber 1, and then enter the filling chamber 4 through the liquid collecting chamber 8, and perform a second separation in the filling chamber 4, and then enter the defoaming chamber 5 through the filling chamber 4 for a third separation. The centrifugal chamber 1, the filling chamber 4 and the defoaming chamber 5 can all perform gas-liquid separation on the gas passing therethrough, that is, the liquid droplets entrained by the gas can be separated from the gas phase. The present application forms redundancy of the separation process by setting up a variety of gas-liquid separation chambers, thereby ensuring the amount of liquid droplets removed from the gas entrained with different liquid droplets.

[0027] The specific structure and distribution of each gas-liquid separation chamber in the present application are described in detail below. In the embodiment of the present application, the cylinder 9 is vertically arranged, and the exhaust port 72 is opened at the top of the cylinder 9. In the vertical direction, the liquid collecting chamber 8 is located at the lower part of the cylinder 9. The liquid collecting chamber 8 is used to collect the separated droplets. The liquid collecting chamber 8 is arranged at the lower part of the cylinder 9, and the gravity of the separated droplets can be used to collect the droplets; it can be understood that the centrifugal chamber 1, the filling chamber 4 and the defoaming chamber 5 are connected in sequence, but the liquid collecting chamber 8 can be directly or indirectly connected with the centrifugal chamber 1, the filling chamber 4 and the defoaming chamber 5, so that the droplets separated from each chamber can be finally collected in the liquid collecting chamber 8.

[0028] The defoaming chamber 5 is located at the upper part of the barrel 9, and a plurality of defoaming nets are arranged in the defoaming chamber. For example, the height of the defoaming net is 150 mm, and more than 98% of the droplets of 3 μm to 5 μm in the gas are effectively captured. Those skilled in the art can also select parameters such as the height and density of the defoaming net according to their needs. The defoaming net can separate tiny droplets, so the defoaming chamber 5 is arranged at the upper part of the barrel 9 as the last separation process. After passing through the defoaming chamber, the gas can be discharged from the barrel through the exhaust port 72.

[0029] The centrifugal chamber 1 is located in the middle of the barrel 9, that is, in the vertical direction, the centrifugal chamber 1 is located between the defoaming chamber 5 and the liquid collecting chamber 8, and the air inlet 71 is connected to the centrifugal chamber 1. By arranging the centrifugal chamber 1 in the middle of the barrel 9, a larger layout space can be provided for the centrifugal chamber 1. Since the air inlet 71 is connected to the centrifugal chamber 1, the centrifugal chamber 1 needs to perform the first gas-liquid separation process on the gas, thereby separating most of the water in the gas from the gas.

[0030] In the transverse direction (radial direction of the cylinder 9), the filling chamber 4 is located outside the centrifugal chamber 1, that is, between the side wall of the cylinder 9 and the centrifugal chamber 1, so that the middle space of the cylinder 9 can be used to arrange two gas-liquid separation chambers, thereby improving the utilization rate of the space inside the cylinder 9.

[0031] As shown in the figure, in a specific embodiment, at least part of the centrifugal chamber 1 is in a conical structure, the conical structure has a large diameter end 113 and a small diameter end 114, the central axis of the conical structure extends in the vertical direction, the large diameter end 113 is located on the upper side of the small diameter end 114, and the central axis of the conical structure refers to the line connecting the centers of the large diameter end 113 and the small diameter end 114; the centrifugal chamber 1 also includes a cover 12, the cover 12 is used to seal the large diameter end 113 of the conical structure, thereby preventing the gas from escaping from the large diameter end 113, and the small diameter end 114 of the conical structure is provided with an opening, and the centrifugal chamber 1 and The liquid collecting chamber 8 is connected through the small diameter end 114; when the gas to be treated enters the conical structure, the gas will change from linear motion to circular motion, and flow downward in a spiral along the inner wall of the conical structure. In this process, the liquid droplets are thrown out by the gas under the action of centrifugal force and fall along the inner wall of the conical structure, and enter the liquid collecting chamber 8 from the small diameter end 114. At the same time, the gas also enters the liquid collecting chamber 8 from the small diameter end 114. In this way, the gas can enter the liquid collecting chamber 8 through the centrifugal chamber 1 according to the set route, and enter other gas-liquid separation chambers through the liquid collecting chamber 8.

[0032] Specifically, the conical structure has a conical side wall 11, which is curled to form a conical structure. The conical side wall 11 is spaced from the inner wall of the barrel 9. The cover body 12 connected to the large diameter end 113 can be a circular plate welded to the large diameter end 113, or it can be a cylindrical structure with one end closed and the other end open. Technical personnel in this field can choose according to their needs. The side wall of the cover body 12 is connected to the inner wall of the barrel 9 through a mounting beam. Of course, the cover body 12 itself can also be not directly connected to the inner wall of the barrel 9, but indirectly connected to the inner wall of the barrel 9 through the conical side wall 11.

[0033] The large diameter end 113 and the small diameter end 114 are radially outwardly formed with an upper flange 111 and a lower flange 112, and the outer peripheral walls of the upper flange 111 and the lower flange 112 are fixed to the inner wall of the barrel 9. A barrel side plate 41 is connected between the upper flange 111 and the lower flange 112, and the barrel side plate 41 is curled into a cylindrical structure. The upper surface of the barrel side plate 41 is welded to the lower surface of the upper flange 111, and the lower surface of the barrel side plate 41 is welded to the upper surface of the lower flange 112, so that at least part of the lower surface of the upper flange 111, at least part of the upper surface of the upper flange 111, the outer wall of the barrel side plate 41 and the inner wall of the barrel are surrounded to define an annular cavity, and at least part of the annular cavity serves as a packing cavity 4, and the packing cavity 4 is filled with Raschig rings The diameter of the Raschig ring filler is 8~10mm. Through the full contact between the gas and the Raschig ring filler, some droplets are retained and discharged, thereby separating the gas and liquid flowing through it; the lower surface of the lower flange 112 and the inner wall of the cylinder 9 define a liquid collecting chamber 8, and the liquid collecting chamber 8 is connected to the filler chamber 4. In this way, the gas entering the liquid collecting chamber 8 from the centrifugal chamber 1 can enter the filler chamber 4 for secondary separation. At the same time, the droplets separated by the filler chamber 4 can also be collected in the liquid collecting channel.

[0034] In the above embodiment, a condensation chamber 2 is also enclosed and defined between part of the upper surface of the lower flange 112, the inner wall of the cylinder side plate 41 and the outer wall of the cone side plate, and the liquid collecting chamber 8 and the packing chamber 4 are connected through the condensation chamber 2, that is, in the gas flow direction, a condensation chamber 2 is also provided between the liquid collecting chamber 8 and the packing chamber 4; the outer wall surface of the cone side wall 11 constitutes a part of the chamber wall of the condensation chamber 2, thereby improving the integration of each gas-liquid separation chamber, increasing the space utilization of the cylinder 9, and simplifying the structure inside the cylinder 9. At the same time, by providing the condensation chamber 2, the gas is further condensed, thereby increasing the number of separation processes.

[0035] Specifically, the gas-liquid separator has a first channel 61, which is used to connect the liquid collecting chamber 8 and the condensing chamber 2. The first channel 61 penetrates the chamber wall of the condensing chamber 2 to form a first port 611; that is, the first channel 61 penetrates the portion of the lower flange 112 located in the condensing chamber 2, and forms a first port 611 on the upper surface of the lower flange 112. The first port 611 is vertically opposite to the cone side wall 11 and is located on the lower side of the cone side wall 11. In this way, the gas in the liquid collecting chamber 8 enters the condensing chamber 2 through the first port 611 at a certain speed and then collides with the outer wall surface of the cone side wall 11, thereby separating the liquid droplets from the gas. The separated liquid droplets will drip to the bottom of the condensing chamber 2 and flow into the liquid collecting chamber 8 through the lower flange 112.

[0036] In an optional embodiment, an annular partition plate 42 is further provided in the annular cavity. The partition plate 42 is arranged horizontally to separate the annular cavity into an upper cavity and a lower cavity. The upper cavity and the lower cavity are distributed vertically. The upper cavity serves as the packing cavity 4, and the lower cavity serves as the rectifying cavity 3. The rectifying cavity 3 is connected with the packing cavity 4. Specifically, the lower cavity is between the lower surface of the partition plate 42 and the upper surface of the portion of the lower flange 112 located in the annular cavity. The lower cavity serves as the rectifying cavity 3. In the flow direction of the gas, the rectifying cavity 3 is located between the condensation cavity 2 and the packing cavity 4. The rectifying cavity 3 is used to rectify the gas entering the packing cavity 4. By providing the rectifying cavity 3 to rectify the gas entering the packing portion, the contact area between the gas and the packing can be increased, the speed at which the gas passes through the packing cavity 4 can be adjusted, and the separation effect of the packing cavity 4 can be optimized.

[0037] In this embodiment, in the gas flow direction, a condensation chamber 2 is further provided between the liquid collecting chamber 8 and the packing chamber 4, and the rectifying chamber 3 is located between the condensation chamber 2 and the packing chamber 4; the condensation chamber 2 is connected with the packing chamber 4 through the rectifying chamber 3; in the vertical direction, the packing chamber 4 is located on the upper side of the rectifying chamber 3. In this way, the separated water droplets in the packing chamber 4 can flow back to the rectifying chamber 3, and flow back to the condensation chamber 2 through the rectifying chamber 3, and finally flow from the condensation chamber 2 into and be collected in the liquid collecting chamber 8.

[0038] Specifically, the gas-liquid separator has at least one second channel and at least one third channel. The second channel is used to connect the condensation chamber 2 and the rectification chamber 3, that is, the second channel extends in the horizontal direction and passes through the part of the cylinder side plate 41 located in the rectification chamber 3. The second channel forms a second opening on the inner wall of the condensation chamber 2, and the second opening is opposite to the cone side wall 11 in the transverse direction. That is, the second channel passes through the inner surface of the cylinder side plate 41 to form a second opening, and the second opening is opposite to the cone side wall 11 in the radial direction. This can facilitate the gas to enter the rectification chamber 3 from the condensation chamber 2, while avoiding the gas from the first opening 611 to form gas resistance to the droplets when the droplets flow into the condensation chamber 2 through the second channel. Preferably, a plurality of second channels are provided in the part of the cylinder side plate 41 located in the rectification chamber 3, so as to form a better gas-liquid connection effect.

[0039] The third channel is used to connect the rectifying cavity 3 and the filling cavity 4; that is, the third channel extends vertically and passes through the partition plate 42. Similarly, the partition plate 42 is provided with a plurality of third channels, thereby increasing the contact area between the gas and the filling in the filling cavity 4. The extension directions of the second channel and the third channel are arranged at an angle, thereby forming a rectifying effect. That is to say, the extension directions of the second channel and the third channel are not only perpendicular to each other, but can also be arranged at an acute angle or an obtuse angle, that is, the second channel or the third channel extends at an angle, etc.

[0040] In the above-mentioned embodiment, the separated droplets are finally collected in the liquid collecting chamber 8, and a liquid level detection device is provided in the liquid collecting chamber 8. The liquid level detection device is connected to the controller, so that when the liquid in the liquid collecting chamber 8 reaches a certain height, the liquid is automatically discharged.

[0041] By adopting the gas-liquid separator of the present application, the following effects can be achieved:

[0042] First, the separation effect is better. In the flow direction of the gas, the water content of the gas located upstream is higher than that of the gas located downstream. Based on this, the centrifugal chamber 1 (to remove large-sized droplets), the filling chamber (to remove medium-sized droplets) and the defoaming chamber 5 (to remove tiny-sized droplets) are arranged in sequence in the flow direction of the gas, and the various gas-liquid separation chambers are reasonably combined in a limited space, thereby improving the utilization rate of the space in the cylinder 9.

[0043] Second, better adaptability. The gas-liquid separation principle of each gas-liquid separation chamber in the present invention is selected based on the large and unstable characteristics of droplet entrainment in this application scenario. The separation effect of each gas-liquid separation chamber is gradually enhanced, and liquid discharge is safe and controllable.

[0044] Third, the material selection is more economical and durable. All parts in contact with the gas in the gas-liquid separator are made of 316L stainless steel. The material selection is both economical and can minimize the intergranular corrosion of the gas on the material.

[0045] The principles and implementation methods of the present invention are described in this article using specific examples. The description of the above embodiments is only used to help understand the core idea of ​​the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
