Description

Technical Field

[0001] This utility model relates to the field of gas-liquid separation technology, and in particular to a three-stage gas-liquid separator. Background Technology

[0002] Traditional gas-liquid separators rely on their tangential air inlets to cause the gas entering the separator to spiral down along the inner wall, causing the liquid droplets in the gas to generate centrifugal force and strike the baffle to separate. Under high humidity or high flow rate conditions, small droplets are difficult to capture effectively due to insufficient inertia, resulting in a high droplet escape rate and limited separation efficiency.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model discloses a three-stage gas-liquid separator to solve the problem that small droplets are difficult to capture effectively due to insufficient inertia, resulting in a high droplet escape rate and limited separation efficiency under high humidity or high flow rate conditions.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A three-stage gas-liquid separator, characterized in that it comprises:

[0007] The cylinder has a tangential air inlet pipe at its outer top end and an exhaust pipe at its top end.

[0008] A ring-shaped filter screen is disposed inside the cylinder and divides the cylinder into a gas zone and a liquid zone.

[0009] A conical baffle is disposed inside the cylinder. The end of the conical baffle with a larger inner diameter is connected to the top of the cylinder, and the end of the conical baffle with a smaller inner diameter is connected to the top of the annular filter screen. The conical baffle separates the gas zone into an exhaust zone and a swirling zone and connects the liquid zone with the exhaust pipe.

[0010] The inclined plates are of several kinds, and the inclined plates are evenly distributed along the inner wall of the cylinder and are located at the top of the annular filter screen.

[0011] A further technical solution is that the inclined plate has fourteen pieces, one end of the inclined plate is connected to the inner wall of the cylinder, and the other end is connected to the outer wall of the cone baffle. The inclined plate is inclined at 30° relative to the horizontal plane.

[0012] A further technical solution is that the annular filter screen includes fourteen filter screen segments, which are arranged circumferentially and detachably connected at the ends. The filter screen segments are 30mm×30mm mesh grid steel wire mesh.

[0013] A further technical solution is that a conical baffle is mounted at the bottom of the liquid zone, with the top of the conical baffle facing the exhaust zone.

[0014] A further technical solution is that two level gauge ports, spaced vertically apart, are provided on the side wall of the cylinder corresponding to the position of the liquid zone.

[0015] A further technical solution is that a sight glass is provided on the side wall of the cylinder at a position corresponding to the liquid zone.

[0016] A further technical solution is that a support is provided at the bottom end of the cylinder.

[0017] A further technical solution is that a wastewater pipe is provided on the side wall of the cylinder at a position corresponding to the liquid zone, and the wastewater pipe is connected to the liquid zone.

[0018] The beneficial effects of this utility model embodiment are as follows:

[0019] (I) A three-stage gas-liquid separator includes a cylinder, an annular filter, a conical baffle, and inclined plates. The gas-liquid mixture is injected into the cylinder at high speed from the tangential inlet pipe, forming a strong rotating airflow along the cylinder wall in the swirling zone. Some droplets are thrown towards the cylinder wall by centrifugal force, and after impacting the conical baffle, they coalesce and increase in size. The circumferentially evenly distributed inclined plates are located downstream of the swirling zone. Some droplets are further coalesced by inertial collisions in the gaps between the inclined plates. The airflow carrying residual microdroplets passes downward through the annular filter, where the microdroplets are intercepted. The separated dry gas rises through the internal channel of the conical baffle and is discharged from the top exhaust pipe. The droplets are separated step by step through spiral centrifugal separation, inclined plate impact separation, and annular filter capture, which reduces the escape rate of small droplets and improves the separation efficiency of the device under high temperature and high humidity conditions.

[0020] (ii) Furthermore, a conical baffle is installed at the bottom of the liquid zone, with the apex of the conical baffle facing the exhaust zone. The downward airflow vertically impacts the upper surface of the conical baffle, reducing the airflow velocity and eliminating the suction effect of the rising high-speed airflow on the liquid surface, thus preventing the separated droplets from being entrained by the gas again.

[0028] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0029] First embodiment:

[0030] A three-stage gas-liquid separator includes a cylinder 100, an annular filter screen 200, a conical baffle 300, and an inclined plate 400.

[0031] like Figures 1-3 As shown, a tangential air inlet pipe 101 is provided at the top outer side of the cylinder 100. Specifically, the air inlet direction of the air inlet pipe 101 is perpendicular to the axial direction of the cylinder 100. An exhaust pipe 102 is provided at the top of the cylinder 100. For example, a bracket 103 is also provided at the bottom of the cylinder 100. An inspection port 104 is also provided on the outer side of the cylinder 100.

[0032] like Figure 1 and Figure 4As shown, the annular filter 200 is disposed inside the cylinder 100 and divides the cylinder 100 into a gas zone 110 and a liquid zone 120. For example, the annular filter 200 includes fourteen filter segments 201, which are arranged circumferentially and detachably connected at the ends. Each filter segment 201 is a 30mm × 30mm mesh grid steel wire mesh. Its pore size ensures low airflow resistance while efficiently intercepting liquid droplets. The split design improves the efficiency of disassembly and maintenance when the filter is partially clogged, avoiding the cost of overall replacement. The grid steel wire mesh structure can withstand swirling impacts, preventing deformation and failure, and is particularly suitable for long-term stable operation under high humidity and high flow rate conditions.

[0033] like Figure 1 and Figure 5 As shown, a conical baffle 300 is disposed inside the cylinder 100. The end of the conical baffle 300 with a larger inner diameter is connected to the top of the cylinder 100, and the end of the conical baffle 300 with a smaller inner diameter is connected to the top of the annular filter screen 200. The conical baffle 300 separates the gas zone 110 into an exhaust zone 111 and a swirling zone 112, and connects the liquid zone 120 to the exhaust pipe 102. For example, a wastewater pipe 105 is also provided on the side wall of the cylinder 100 at a position corresponding to the liquid zone 120, and the wastewater pipe 105 connects to the liquid zone 120.

[0034] like Figure 1 and Figure 4 As shown, there are several inclined plates 400, which are evenly distributed circumferentially along the inner wall of the cylinder 100 and located at the top of the annular filter screen 200. For example, there are fourteen inclined plates 400. One end of each inclined plate 400 is connected to the inner wall of the cylinder 100, and the other end is connected to the outer wall of the conical baffle 300. The inclined plates 400 are inclined at 30° relative to the horizontal plane, and the distance between two inclined plates 400 is 30 mm.

[0035] like Figure 1 As shown, a conical baffle 500 is further provided at the bottom of the liquid zone 120, with the apex of the conical baffle 500 facing the exhaust zone 111. The downward airflow vertically impacts the upper surface of the conical baffle 500, reducing the airflow velocity and eliminating the suction effect of the rising high-speed airflow on the liquid surface, thus preventing the separated droplets from being entrained by the gas again.

[0036] like Figure 1 As shown, furthermore, two level gauge ports 106, spaced vertically, are provided on the side wall of the cylinder 100 at positions corresponding to the liquid zone 120. The spaced vertically spaced double level gauge ports 106 are used to install level gauges to monitor the liquid level height in the liquid zone 120 in real time, enabling timely discharge of waste liquid and ensuring the continuous and stable operation of the separator.

[0037] like Figure 1As shown, a sight glass 107 is further provided on the side wall of the cylinder 100 at a position corresponding to the liquid zone 120. The sight glass 107 provides a direct visual observation window for the liquid level and liquid water state of the liquid zone 120, assists in verifying the accuracy of the level gauge reading, and allows for immediate observation of whether the liquid zone 120 requires maintenance, providing visual assurance for equipment maintenance.

[0038] In operation, this embodiment is as follows:

[0039] A gas-liquid mixture is injected at high speed into the cylinder 100 through the tangential inlet pipe 101, forming a strong rotating airflow along the cylinder wall in the swirl zone 112. Some droplets are thrown towards the cylinder wall by centrifugal force, and after impacting the conical baffle 300, they coalesce and increase in size. Some droplets are further coalesced by inertial collisions in the gap of the inclined plate 400. The airflow carrying residual microdroplets passes downward through the annular filter 200, where the microdroplets are intercepted, and the liquid water flows into the liquid zone 120. The separated dry gas rises through the internal channel of the conical baffle 300 and is discharged from the top exhaust pipe 102. The separated gas encounters the conical baffle 500 at the bottom of the liquid zone 120. The gas impacts the top surface of the conical baffle 500, reducing the airflow speed. The decelerated gas turns upward and is discharged from the exhaust pipe 102 through the exhaust zone 111 within the conical baffle 300. The liquid accumulated in the liquid zone 120 is stably discharged through the wastewater pipe 105, and the liquid level is monitored in real time by the sight glass 107 and the liquid level gauge 106.

[0040] In this embodiment, the droplets are separated step by step through spiral centrifugal separation, inclined plate 400 impact separation, and annular filter 200 capture and separation, which reduces the escape rate of tiny droplets and improves the separation efficiency of the device under high temperature and high humidity conditions.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
