Description
Technical Field
[0001] The present application relates to the technical field of water treatment equipment, and in particular to a gas-liquid separation device of a gas stripping device. Background Art
[0002] In water treatment equipment, process requirements often necessitate piping systems for water lift and return at the back end. However, because the treated water contains air, the more bubbles there are, the more air there is. When gas lift is used, this air can flow through the pipes to the back end, affecting the stability of the water flow.
[0003] Currently, there are three common ways to solve the problem of gas-liquid separation. The first is to open an exhaust hole in the rear-end pipe. This design has a low structural cost and is simple to make. However, it is prone to splashing, causing dirt or liquid in the pipe to flow out, resulting in water leakage between partitions; the second is to set up a branch pipe in the rear-end pipe to a very high place for exhaust. This design structure can solve the exhaust problem. However, the application occasions are very restrictive and the versatility is poor. The third is to set up a large-volume gas-liquid separation chamber or a large-volume gas-liquid separation structure after the gas and liquid are lifted. Although this solves the problem of gas-liquid separation, the structural design is complex, the cost is high, and there are space limitations.
[0004] Therefore, the above-mentioned technical defects need to be changed urgently. Utility Model Content
[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present application is to provide a gas-liquid separation device for a gas stripping device, which is intended to discharge the gas in the water pipe and avoid water spraying during the exhaust process.

[0008] The exhaust pipe body includes a connecting end and an exhaust end, and the connecting end and the exhaust end are connected to each other to form a through hole;

The exhaust hole is connected with the upper end of the annular inverted groove, and the exhaust hole is set at a position on the annular inverted groove that deviates from the sealing disk.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components.

[0032] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.
[0033] The utility model provides Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, a gas-liquid separation device of a gas lift device is installed on a water pipe and is used to discharge air in the water pipe. Its main structure includes: an exhaust pipe body 1 and an exhaust cap 2. The exhaust pipe body 1 includes a connecting end 11 and an exhaust end 12. The connecting end 11 and the exhaust end 12 are connected to each other to form a through hole 13. Among them, the connecting end 11 is used to connect the water pipe, so that the water in the water pipe enters the through hole 13 and the air in the water pipe is discharged through the exhaust end 12. The exhaust cap 2 is set on the exhaust end 12. The outer edge of the exhaust cap 2 is provided with an annular undercut groove 21. The annular undercut groove 21 is used to clamp the side wall of the exhaust end 12. The middle part of the exhaust cap 2 is concave toward the through hole 13 to form a sealing disk 22. When the internal and external pressures of the exhaust pipe body 1 are the same, the exhaust cap 2 and the exhaust end 12 are tightly fastened to form a sealed structure. Among them, there is a gap between the inner wall of the exhaust end 12 and the sealing disk 22, and at least one exhaust hole 23 is opened on the exhaust cap 2, and the exhaust hole 23 is connected with the upper end of the annular inverted groove 21, and the exhaust hole 23 is set at a position on the annular inverted groove 21 that deviates from the sealing disk 22. When the internal pressure of the exhaust pipe body 1 is greater than the external pressure, the exhaust cap 2 expands and deforms, and the annular inverted groove 21 is lifted, and a gap is generated between it and the exhaust end 12, so that the air in the through hole 13 is guided from the gap to the exhaust hole 23, thereby achieving the technical effect of exhaust. It should be noted that the concave sealing disk 22 facilitates the molding of the annular inverted groove 21. The deeper the concave of the sealing disk 22, the greater the extension depth of the annular inverted groove 21 along the exhaust pipe body 1, and the longer the path for gas discharge. A longer drainage path can achieve a better water-gas separation effect.
[0034] It should be noted that there are three common ways to solve the problem of air blockage. The first is to open an exhaust hole 23 in the rear end pipe. This design has low structural cost and is simple to make. However, it is prone to splashing, causing dirt or liquid in the pipe to flow out; the second is to set up a branch pipe in the rear end pipe to a very high place for exhaust. This design structure can solve the exhaust problem. However, the application occasions are very restrictive and the versatility is poor. The third is to set up a large-volume gas-liquid separation chamber or a large-volume gas-liquid separation structure after the gas and liquid are lifted. Although this solves the problem of gas-liquid separation, the structural design is complex, the cost is high, and there are space limitations.
[0035] The device of the present invention is provided with an exhaust cap 2 at the upper end of the exhaust pipe body 1, and an exhaust hole 23 is opened on the exhaust cap 2 at a position corresponding to the annular inverted groove 21. The water flow and gas flowing in from the connecting end 11 will increase the pressure on the sealing disk 22, causing it to deform upward, thereby creating a gap between the side wall of the exhaust end 12 and the upper end of the annular inverted groove 21, so that the gas on the annular inverted groove 21 flows through the gap to the exhaust hole 23, thereby achieving the exhaust effect. Among them, the gap between the sealing disk 22 and the annular inverted groove 21 forms a channel, and the channel is annular, and the path of the channel to the exhaust hole 23 includes at least one corner. Therefore, part of the water flow will be blocked by the corners of the sealing disk 22 and the annular inverted groove 21, effectively reducing the occurrence of water spraying.
[0036] Further, such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 As shown, the exhaust cap 2 is provided with at least one pair of exhaust holes 23, and the two exhaust holes 23 are symmetrically arranged around the periphery of the exhaust cap 2. The two exhaust holes 23 are symmetrically arranged around the periphery of the exhaust cap 2, so that the air discharge can be more balanced and the exhaust effect is better.
[0037] Further, such as Figure 1 、 Figure 4 、 Figure 5 As shown, the exhaust cap 2 is detachably connected to the exhaust end 12 , and a clamping piece 14 is provided at one end of the exhaust pipe body 1 , through which the exhaust cap 2 is clamped to the one end of the exhaust pipe body 1 .
[0038] It should be noted that there is a certain movable gap between the exhaust cap 2 and the exhaust end 12 in the extending direction of the exhaust pipe body 1, so that when the air pressure inside the exhaust pipe body 1 is high, the exhaust cap 2 can be pushed upward, thereby connecting the interior of the exhaust pipe body 1 with the exhaust hole 23.
[0039] Further, such as Figure 4 、 Figure 5 and Figure 6 As shown, the clamping member 14 is configured as a circular step structure with a chamfered surface 141 at its upper end. An abutment ring 24 is provided within the annular undercut groove 21 at a position corresponding to the circular step structure. The abutment ring 24 abuts the circular step structure to secure the exhaust cap 2 to the exhaust end 12. A certain clearance exists between the abutment ring 24 and the circular step structure in the direction in which the exhaust pipe body 1 extends. The chamfered surface 141 at the upper end of the circular step structure facilitates installation of the exhaust cap 2.
[0040] Further, such as Figure 5As shown, a triangular ring rib 221 is provided at the edge of the side of the sealing disk 22 facing the connection end 11, and the triangular ring rib 221 is integrally formed with the sealing disk 22. The triangular ring rib 221 can increase the structural strength of the edge of the sealing disk 22. When the water pressure in the water pipe is relatively high, the sealing disk 22 will bulge outward under the action of the water pressure. At this time, the triangular ring rib 221 has a certain supporting effect, which can effectively reduce the shrinkage of the edge of the sealing disk 22 under the action of the water pressure. In addition, it can prevent the gap between the inner wall of the exhaust end 12 and the sealing disk 22 from changing significantly. Improve the exhaust stability.
[0041] Furthermore, a fixing strap 3 is provided between the exhaust cap 2 and the exhaust pipe body 1, connecting one end of the exhaust pipe body 1. The fixing strap 3 is generally used to connect the exhaust cap 2 and the exhaust pipe body 1. At least one end of the fixing strap 3 connecting the exhaust cap 2 and the exhaust pipe body 1 is configured to be detachable to facilitate later maintenance and replacement.
[0042] Furthermore, the exhaust cap 2 is configured as a soft material structure. The soft material structure can be deformed under a certain pressure, making it easier to form a channel between the through hole 13 and the exhaust hole 23. It also makes it easier to maintain and replace it later.
[0043] Further, such as Figure 5 As shown, the inner side wall of the connecting end 11 is provided with a first abutting step 111 , and the first abutting step 111 extends along the circumferential direction of the exhaust pipe body 1 .
[0044] Further, such as Figure 5 As shown, the outer wall of the connecting end 11 is provided with a second abutting step 112, which extends along the circumferential direction of the exhaust pipe body 1. It is understandable that both the inner and outer sides of the connecting end 11 can be used to sleeve water pipes, and the first abutting step 111 and the second abutting step 112 can respectively abut the inner and outer water pipes sleeved on the connecting end 11.
[0045] Furthermore, at least one of the exhaust cap 2 and the exhaust pipe body 1 is configured as a transparent material structure.
[0046] It is understandable that the transparent material structure can facilitate the staff to observe the internal conditions of the exhaust pipe body 1, and facilitate maintenance and problem troubleshooting.
[0047] In summary, the present application provides a gas-liquid separation device for a gas lift device. The device of the utility model is provided with an exhaust cap 2 at the upper end of the exhaust pipe body 1, and an exhaust hole 23 is opened at a position corresponding to the annular inverted groove 21 on the exhaust cap 2. The water flow and gas flowing into the connecting end 11 will increase the pressure on the sealing disk 22, causing it to deform upward, thereby creating a gap between the side wall of the exhaust end 12 and the upper end of the annular inverted groove 21, so that the gas on the annular inverted groove 21 flows through the gap to the exhaust hole 23, thereby achieving the exhaust effect. During this period, part of the water flow will be blocked by the corners of the sealing disk 22 and the annular inverted groove 21, effectively avoiding water spraying.
[0048] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
