Description

Technical Field

[0001] This application relates to the technical field of gas-water separators, and in particular to a gas-water separator with a circulation system. Background Technology

[0002] Gas-liquid separators are mainly used in industrial liquid systems to separate gas and liquid, improve the dryness of steam, and reduce the phenomenon of water carryover in steam. The gas to be processed enters the body through the inlet and moves downward at high speed, separating the water in the steam and collecting it in the water collection tank at the bottom. There is a drain outlet to discharge it. The gas after gas-liquid separation will enter the subsequent pipeline through the middle guide pipe and the outlet.

[0003] For related technologies, please refer to Chinese Patent No. CN209630786U, which discloses a gas-water separator, including a shell, a gas-water mixing inlet, a gas outlet, a drain outlet, an observation window, and a support column. The right end of the shell is provided with a gas-water mixing inlet, the top end of the shell is provided with a gas outlet, the bottom end of the shell is provided with a drain outlet, the surface of the shell is also provided with an observation window, and the bottom end of the shell is also provided with a support column.

[0004] Regarding the aforementioned technologies, it is impossible to monitor the moisture content of the gas after a single gas-water separation process. The separated gas may still contain moisture, indicating incomplete separation and affecting subsequent use. Utility Model Content

[0005] To facilitate monitoring of the moisture content in the air after gas-water separation, this application provides a gas-water separator with a circulation system.

[0006] This application provides a gas-liquid separator with a circulation system, which adopts the following technical solution:

[0007] A gas-liquid separator with a circulation system includes a cylindrical body with a separation chamber inside. A fixed plate is fixedly installed inside the separation chamber, dividing the separation chamber into a first chamber and a second chamber. A flow divider is installed inside the separation chamber, passing through and fixedly connected to the fixed plate. A gas rising opening is provided at the bottom of the flow divider. A guide plate is spirally installed on the outer wall of the flow divider below the fixed plate. An inlet pipe and an outlet pipe are respectively connected to both sides of the cylindrical body. The inlet pipe communicates with the second chamber, and the outlet pipe communicates with the first chamber. A circulation assembly is provided at the other end of the outlet pipe. The circulation assembly includes a three-way pipe and an external control module. The outlet pipe is connected to one end of the three-way pipe, and a humidity detector is installed inside the outlet pipe. The other two ends of the three-way pipe are connected to a return pipe and a delivery pipe. A first automatic control valve is installed inside the return pipe, and the other end of the return pipe is connected to the inlet pipe. A second automatic control valve is installed inside the delivery pipe, and the other end of the delivery pipe is connected to the outside of the cylinder. The humidity detector is electrically connected to a judgment module, which is electrically connected to the external control module. The external control module is electrically connected to the first automatic control valve and the second automatic control valve.

[0008] By adopting the above technical solution, steam enters the second chamber through the inlet pipe. The steam rotates at high speed along the spiral channel formed by the spirally arranged guide plates, generating centrifugal force. This centrifugal force amplifies the density difference between gas and liquid, causing the moisture in the denser steam to be thrown towards the inner wall of the cylinder and the guide plates. It then flows along the inner wall and guide plates of the second chamber to the bottom. The gas, now free of moisture, gathers towards the center under centrifugal force and enters the distribution cylinder through the gas rising opening. From there, it enters the outlet pipe connected to the first chamber. A humidity detector in the outlet pipe detects the humidity of the discharged gas and generates a humidity signal. This signal is transmitted to the judgment module, which uses a preset humidity level of 20% RH. When the humidity signal is greater than a preset baseline value, the judgment module determines that the gas humidity is greater than 20% RH and outputs a humidity signal to the external control module. The external control module receives the humidity signal output by the judgment module, controls the first automatic control valve to open, and simultaneously controls the second automatic control valve to close. The gas enters the outlet pipe through the return pipe for secondary gas-water separation. When the humidity signal is less than or equal to the preset baseline value, the judgment module determines that the gas humidity is less than or equal to 20% RH and outputs a qualified signal to the external control module. The external control module receives the qualified signal output by the judgment module, controls the first automatic control valve to close, and simultaneously controls the second automatic valve to open. The gas is delivered to the subsequent pipeline through the delivery pipe, facilitating the monitoring of the moisture content in the air after gas-water separation.

[0009] Optionally, a one-way valve is provided inside the return air pipe near the point where it connects with the intake air pipe.

[0010] By adopting the above technical solution, when the first automatic control valve is opened, the one-way valve allows the gas in the return pipe to enter the intake pipe from the return pipe, while the one-way valve prevents the steam in the intake pipe from entering the return pipe.

[0011] Optionally, the inner wall of the top of the first chamber is configured as a first arc-shaped surface that is low around the edges and high in the middle, and the inner wall of the bottom of the second chamber is configured as a second arc-shaped surface that is high around the edges and low in the middle.

[0012] By adopting the above technical solution, the first arc-shaped surface guides the trajectory of the gas rising from the diverter, and smoothly turns the gas along the first arc-shaped surface. The residual moisture in the gas adheres to the first arc-shaped surface due to gravity and flows down along the inner wall of the first arc-shaped surface, thereby improving the gas-water separation efficiency. The second arc-shaped surface allows the moisture separated from the second chamber and the guide plate to gather together from all sides to the center due to gravity.

[0013] Optionally, a drain pipe is connected to the center of the bottom of the second chamber, and the drain pipe is connected to an automatic drainer, the automatic drainer being model NP-168.

[0014] By adopting the above technical solution, the water in the second arc-shaped surface flows into the drain pipe through the arc surface, and the automatic drainer discharges the water accumulated in the drain pipe.

[0015] Optionally, the fixing plate is inclined, and a water outlet hole is provided through the fixing plate near the lower end.

[0016] By adopting the above technical solution, the water separated from the steam on the first arc-shaped surface flows along the inclined angle of the fixed plate to the water outlet, which facilitates the discharge of the water separated in the first chamber.

[0017] Optionally, a water outlet pipe is vertically arranged in the second chamber, one end of which is connected to a water outlet hole, and the other end of which is located in the second chamber.

[0018] By adopting the above technical solution, the water outlet pipe introduces water from the first chamber into the second chamber.

[0019] Optionally, the cylinder includes an upper shell and a lower shell, the upper shell being located on the lower shell, and the upper shell and the lower shell being connected by a flange.

[0020] By adopting the above technical solution, the upper and lower shells can be disassembled, which facilitates the maintenance of the internal components of the cylinder.

[0021] Optionally, the bottom of the cylinder is provided with several support columns.

[0022] By adopting the above technical solution, the support column supports the cylinder.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Steam enters the second chamber through the inlet pipe. The steam rotates at high speed along the spiral channel formed by the guide plate. Centrifugal force amplifies the density difference between gas and liquid to separate the steam and water. The gas is discharged from the outlet pipe. The humidity detector in the outlet pipe detects the humidity of the discharged gas and generates a humidity signal. The humidity detector transmits the humidity signal to the judgment module. With 20% RH as the preset benchmark value, if the judgment module determines that the gas humidity is greater than 20% RH, it outputs a humidity signal to the external control module. The external control module controls the first automatic control valve to open and the second automatic control valve to close, and the gas undergoes secondary gas-water separation. When the judgment module determines that the gas humidity is less than or equal to 20% RH, it outputs a qualified signal to the external control module. The external control module controls the first automatic control valve to close and the second automatic control valve to open, and the gas is discharged into the delivery pipe, which facilitates the monitoring of the moisture content in the air after gas-water separation.

[0025] 2. When the first automatic control valve is opened, the one-way valve allows the gas in the return pipe to be discharged normally from the return pipe into the inlet pipe. The one-way valve blocks the steam in the inlet pipe from entering the return pipe, thus preventing the steam in the inlet pipe from entering the cylinder from the return pipe.

[0031] The present application will be further described in detail below with reference to all the accompanying drawings.

[0032] This application discloses a gas-water separator with a circulation system.

[0033] like Figure 1 A gas-water separator with a circulation system includes a cylinder 1, which comprises an upper shell 15 and a lower shell 16. The upper shell 15 is located on the lower shell 16, and the upper shell 15 and the lower shell 16 are connected by a flange 151. This allows the upper shell 15 and the lower shell 16 to be disassembled for easy maintenance of the internal components of the cylinder 1.

[0034] like Figure 1 The top of the cylinder 1 is equipped with a first arc-shaped surface that is low around the edges and high in the middle, and the bottom of the second chamber is equipped with a second arc-shaped surface that is high around the edges and low in the middle. The first arc-shaped surface can optimize the trajectory of the rising airflow inside the cylinder 1, causing the rising gas to turn along the curved surface; the second arc-shaped surface uses gravity to gather moisture from the edges to the lower center.

[0035] like Figure 1 A drain pipe 51 is connected to the center of the bottom of the second arc-shaped surface, and an automatic drainer 5, model NP-168, is connected to the drain pipe 51. Water on the second arc-shaped surface flows into the drain pipe 51 through the arc surface. The automatic drainer 5 facilitates the discharge of water accumulated in the drain pipe 51 in a measured amount. Several support columns 17 are installed at the bottom of the cylinder 1 to support the cylinder 1.

[0036] like Figure 2 and Figure 3An air inlet pipe 13 and an air outlet pipe 14 are respectively installed on both sides of the cylinder 1. A circulation component 2 is installed at the other end of the air outlet pipe 14. The circulation component 2 includes a three-way pipe 21 and an external control module 22. The air outlet pipe 14 is connected to one end of the three-way pipe 21. A humidity detector 141 is installed inside the air outlet pipe 14. The other two ends of the three-way pipe 21 are connected to a return pipe 3 and a delivery pipe 4. A first automatic control valve 31 is installed inside the return pipe 3. The other end of the return pipe 3 is connected to the air inlet pipe 13. A second automatic control valve 41 is installed inside the delivery pipe 4. The other end of the delivery pipe 4 is connected to the outside of the cylinder 1. The humidity detector 141 is electrically connected to a judgment module 6. The judgment module 6 is electrically connected to the external control module 22. The external control module 22 is electrically connected to the first automatic control valve 31 and the second automatic control valve 41.

[0037] The humidity detector 141 inside the exhaust pipe 14 detects the exhaust gas, generates a humidity signal, and transmits the humidity signal to the judgment module 6.

[0038] A humidity level of 20% RH is set as the preset reference value for the judgment module 6. When the humidity signal is greater than the preset reference value, the judgment module 6 determines that the gas humidity is greater than 20% RH and outputs a humidity signal to the external control module 22. The external control module 22 receives the humidity signal output by the judgment module 6, controls the first automatic control valve 31 to open, and simultaneously controls the second automatic control valve 41 to close. The gas enters the outlet pipe 14 through the return pipe 3 for gas-water separation again. When the humidity signal is less than or equal to the preset reference value, the judgment module 6 determines that the gas humidity is less than or equal to 20% RH and outputs a qualified signal to the external control module 22. The external control module 22 receives the qualified signal output by the judgment module 6, controls the first automatic control valve 31 to close, and simultaneously controls the second automatic valve 41 to open. The gas is transported to the subsequent pipeline through the delivery pipe 4 to ensure that the moisture content of the gas after gas-water separation is qualified.

[0039] like Figure 2 and Figure 4 A one-way valve 32 is installed inside the return pipe 3. When the first automatic control valve 31 is opened, the one-way valve 32 allows the gas in the return pipe 3 to enter the intake pipe 13 from the return pipe 3, while the one-way valve 32 prevents the steam in the intake pipe 13 from entering the return pipe 3.

[0040] like Figure 4The cylinder 1 has a separation chamber, and a fixed plate 11 is fixedly installed in the separation chamber. The fixed plate 11 divides the separation chamber into a first chamber and a second chamber. The air inlet pipe 13 is connected to the second chamber, and the air outlet pipe 14 is connected to the first chamber. A flow divider 12 is installed in the separation chamber. The flow divider 12 passes through the fixed plate 11 and is fixedly connected to the fixed plate 11. A gas rising opening 121 is opened through the bottom of the flow divider 12. A guide plate 122 is spirally installed on the outer wall of the flow divider 12 below the fixed plate 11.

[0041] Steam enters the second chamber through the inlet pipe 13. The steam rotates at high speed along the spiral channel formed by the spirally arranged guide plates 122, generating centrifugal force. This centrifugal force amplifies the density difference between the gas and liquid, causing the denser water in the steam to be thrown towards the inner wall of the cylinder 1 and onto the guide plates 122. The water then flows along the inner wall of the second chamber and the guide plates 122 to the bottom of the second chamber, thus largely expelling the water and forming gas. Under the action of centrifugal force, the gas gathers towards the center and enters the distribution cylinder 12 through the gas rising opening 121. From there, it enters the outlet pipe 14 connected to the first chamber. Centrifugal force reduces the water content in the steam.

[0042] like Figure 4 The fixing plate 11 is installed at an angle, with a water outlet 111 extending through its lower end. A water outlet pipe 112 is installed vertically in the second chamber, with one end connected to the water outlet 111 and the other end located within the second chamber. The first arc-shaped surface guides the trajectory of the gas rising from the diverter 12, causing the gas to smoothly turn along the first arc-shaped surface. Residual moisture in the gas adheres to the first arc-shaped surface due to gravity and flows down along the inner wall of the first arc-shaped surface. The moisture flows along the angle of the fixing plate 11 towards the water outlet 111, and the water outlet pipe 112 carries the moisture from the first chamber to the bottom of the second chamber.

[0043] The implementation principle of the gas-water separator with a circulation system in this embodiment is as follows: Steam enters the second chamber through the inlet pipe 13. The steam rotates at high speed along the spiral channel formed by the spirally arranged guide plate 122, generating centrifugal force. The centrifugal force throws the water in the steam onto the inner wall of the cylinder 1 and the guide plate 122, and flows along the inner wall of the second chamber and the guide plate 122 to the bottom of the second chamber. The gas with separated water gathers towards the center under the action of centrifugal force and enters the interior of the distribution cylinder 12 through the gas rising opening 121. Then, it enters the outlet pipe 14 connected to the first chamber from the interior of the distribution cylinder 12. The humidity detector 141 in the outlet pipe 14 detects the discharged gas. Humidity is measured and a humidity signal is generated. The humidity detector 141 transmits the humidity signal to the judgment module 6. The judgment module 6 determines that the gas humidity is greater than 20% RH and outputs a humidity signal to the external control module 22. The external control module 22 controls the first automatic control valve 31 to open and the second automatic control valve 41 to close. The gas enters the outlet pipe 14 through the return pipe 3 for secondary gas-water separation. When the humidity signal is less than or equal to the preset reference value, the judgment module 6 determines that the gas humidity is less than or equal to 20% RH and outputs a qualified signal to the external control module 22. The external control module 22 controls the first automatic control valve 31 to close and the second automatic control valve 41 to open. The gas is then transported to the subsequent pipeline through the delivery pipe 4.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
