Detailed implementation manners

[0023] For the convenience of those skilled in the art to understand the utility model, the following combines the drawings to illustrate the detailed implementation manners of the utility model.

[0024] As Figures 1 - 5 shown, the utility model provides a steam-water separation device, which includes a shell 1 of the steam-water separator. An auxiliary outlet 12 is arranged inside the shell 1 of the steam-water separator. A separator 13 is arranged outside the auxiliary outlet 12. A limiting member 14 is arranged at the top of the auxiliary outlet 12. A wall seat 11 of the device is arranged outside the auxiliary outlet 12 and on the inner wall of the shell 1 of the steam-water separator;

[0025] The separator 13 includes a separation air frame 1301 and a separation net 1302. The separation air frame 1301 is fixedly connected to the inside of the shell 1 of the steam-water separator. The separation net 1302 covers the top of the separation air frame 1301. The limiting member 14 includes a limiting frame 1401, a support column 1402 and a spiral drive blade 1403. A through hole is opened at the bottom of the limiting frame 1401. The support column 1402 is vertically arranged at the top of the limiting frame 1401. The spiral drive blade 1403 is fixed outside the support column 1402. A collection tank 1404 is opened inside the spiral drive blade 1403;

[0026] A detection meter 8 is arranged outside the shell 1 of the steam-water separator. An air release structure 6 is arranged outside the shell 1 of the steam-water separator. A bottom pipe 7 communicated with the air release structure 6 is arranged outside the separator 13. An air release valve 701 is arranged outside the bottom pipe 7.

[0027] In the structure of the limiting member 14, the spiral transmission blade 1403 can be used to assist the gas to flow to the separator 13, or the liquid can be conveyed at the spiral transmission blade 1403 and the collection tank 1404, and through the auxiliary outlet 12 to the bottom wall of the steam-water separator housing 1. The separation net 1302 covers the top of the separation gas rack 1301. The separation net 1302 is made of a high-density material, which can effectively intercept tiny bubbles to ensure the separation effect. Among them, the structure of the separation net 1302 is well-known in the art, and the application will not elaborate on its structure. The wall seat 11 is used to guide the liquid.

[0028] In this embodiment, an auxiliary foot ladder 5 is provided outside the steam-water separator 13. The auxiliary foot ladder 5 is respectively connected to the air release structure 6 and the bottom pipe 7. An inlet housing 2 is provided at the top of the steam-water separator housing 1. An inlet 201 is opened at the top of the inlet housing 2. The provided inlet 201 is mainly used for the inflow of the mixed fluid. Through the auxiliary foot ladder 5, the operator can conveniently approach the air release structure 6 and the bottom pipe 7 to monitor and adjust the system pressure in real time, ensuring the high-efficiency and stable steam-water separation process and further extending the service life of the equipment.

[0029] In this embodiment, support legs 101 are evenly arranged in a circle at the bottom of the steam-water separator housing 1. The bottom of the support legs 101 is lower than the lowest point of the auxiliary foot ladder 5. The bottom walls of the inlet housing 2 and the steam-water separator housing 1 are both trapezoidal. The trapezoidal bottom wall enhances the structural stability and is convenient for installation and maintenance. The design of the support legs 101 ensures the stability of the device and avoids the risk of tipping over. Each component works together to efficiently separate steam and water and improve the use efficiency.

[0030] In this embodiment, a liquid outlet 3 is connected to the bottom of the steam-water separator housing 1. An exhaust port 9 is provided on one side of the steam-water separator 13. An overflow port 4 is also provided on one side of the steam-water separator housing 1. A detection port 10 is provided on the side wall of the steam-water separator housing 1. The exhaust port 9 is flush with the gas-liquid separator 13. The height of the detection port 10 is higher than the height of the exhaust port 9. When the liquid reaches a certain height in the above structure, it is discharged through the overflow port 4. The provided detection port 10 is used for auxiliary maintenance when the steam-water separator housing 1 fails. A reverse flow prevention device is provided at the outlet of the exhaust port 9 to prevent the separated gas from flowing back and ensure the separation effect. A drain valve is provided at the bottom of the steam-water separator housing 1 to regularly discharge the deposited liquid and maintain the normal operation of the system.

[0031] In this embodiment, the air release structure 6 includes a first air release pipe 601 and a second air release pipe 602. Auxiliary valves 603 are provided on the outer parts of the first air release pipe 601 and the second air release pipe 602. The first air release pipe 601 and the second air release pipe 602 control gas discharge through the auxiliary valves 603. A pressure gauge 702 is provided on the outer part of the bottom pipe 7 to ensure the stability of the system pressure. The first air release pipe 601 and the second air release pipe 602 are respectively connected to different parts of the steam-water separator housing 1. Auxiliary frames 604 are provided on the outer parts of the first air release pipe 601 and the second air release pipe 602. The auxiliary frames 604 are used to fix the air release pipes to prevent their displacement. The pressure gauge 702 is mainly used to monitor the pressure change in the bottom pipe 7 in real time to ensure the safety and controllability of the air release process. When the pressure gauge 702 is higher than a certain level, the excess gas is discharged through a pressure relief valve.

[0032] In this embodiment, a scale is provided on the outer part of the inspection gauge 8, and a transparent pipe is also provided at the center of the inspection gauge 8. By observing the position of the transparent pipe on the scale, the height of the liquid inside the steam-water separator housing 1 can be observed in real time.

[0033] Principle of use: In this application, a mixture of gas and liquid enters at the feeding housing 2 at the top of the steam-water separator housing 1. At this time, the gas flows through the limiting member 14. The structure of the spiral transmission blade 1403 of the limiting member 14 can guide the gas-liquid mixture to the separator 13. A small part of the liquid therein passes through the auxiliary outlet 12 via the collection groove 1404 opened in the spiral transmission blade 1403 to the bottom of the steam-water separator housing 1. The remaining most of the gas-liquid mixture is separated under the action of the separation net 1302. The gas is discharged through the exhaust port 9, and the liquid is deposited at the bottom of the steam-water separator housing 1.

[0034] The liquid separated by the separator 13 flows through the wall seat 11 and is guided to the bottom of the steam-water separator housing 1, where it merges with the liquid flowing out of the auxiliary outlet 12. The formed converged liquid is discharged through the liquid outlet 3. If the liquid level inside the steam-water separator 13 is too high, it is discharged through the overflow port 4 as an auxiliary. Among them, through the inspection gauge 8 on one side of the steam-water separator housing 1, by observing the height of the liquid in the inspection gauge 8, the opening and closing of the discharge valve of the liquid outlet 3 are controlled to assist in discharging the liquid.

[0035] By providing the first air release pipe 601 and the second air release pipe 602 in the air release structure 6, the pressure of the gas-liquid mixture is detected. The pressure gauge 702 in the bottom pipe 7 shows the pressure value of the gas in real time. When the pressure value exceeds a certain threshold, the pressure relief valve 701 can be opened to assist in discharging the gas to ensure the stable operation of the system.

[0036] The separated gas disposed on one side of the separator 13 is discharged through the exhaust port 9. Among them, if the discharged gas and liquid are not appropriate after separation, the gas-liquid mixed fluid is discharged through the detection port 10. The functions of the manual handling limiting member 14 and the separator 13 can also be realized at the detection port 10 to ensure efficient overall operation.

[0037] The above embodiments of the present utility model do not constitute a limitation on the protection scope of the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
