[0002] The steam-water separator is a carbon steel or stainless steel device with a pressure vessel structure. The interface type is a flange structure of DN16 / DN25 / DN40. The steam-water separator must be installed on a horizontal pipeline with the drain outlet facing vertically downward. All caliber steam-water separators are equipped with mounting brackets to reduce the load on the pipeline.

The number of the water outlet pipes 17 is several, and the several water outlet pipes 17 are arranged in a ring shape with equal distances. By providing the water outlet pipes 17, when the temperature of the inner cylinder 16 is too high, the water outlet pipes 17 can be controlled to spray water to avoid damage to the device body due to the excessive temperature of the inner cylinder 16, thereby increasing the service life of the steam-water separator and quickly cooling the liquid at the bottom of the inner cylinder 16 to avoid the temperature of the discharged liquid being too high.

[0023] A pressure relief pipe 18 penetrating into the inner cylinder 16 is arranged at the top of the cylinder 1, and a pressure relief valve 19 is arranged on the outer surface of the pressure relief pipe 18.

A spiral baffle 23 is arranged on the outer surface of the guide cylinder 21. The outer ring size of the spiral baffle 23 is adapted to the inner diameter size of the guide cylinder 21. By arranging the spiral baffle 23, wet steam enters a spiral guide channel and then , with the help of centrifugal force, impulse and vortex action, water with a larger specific gravity is separated from the steam flow with a lighter specific gravity. The water will flow downward along the spiral baffle 23, and the gas will flow downward along the spiral baffle 23 along with the impulse, and then flow upward through the guide cylinder 21.

[0025] Working principle: Open the solenoid valve 5 to allow steam to enter the inner tube 16 from the air inlet pipe 4. Due to centrifugal force and impulse, the steam will rush to the spiral baffle 23 to separate the water and gas in the steam. The water will flow downward along the spiral baffle 23, and due to the impulse, the gas will also flow downward along the spiral baffle 23. When passing through the umbrella plate separator 30, the larger water droplets entrained by the gas will be separated, and the water droplets will condense on the umbrella plate separator 30 and flow downward. Then the gas will flow upward along the guide tube 21, and after passing through the wire mesh demister 26, it can condense smaller water droplets or water vapor, thereby Large water droplets are formed to flow downward, making the steam-water separation more thorough, and the separated gas can be discharged from the air outlet pipe 6 by opening the solenoid valve 2 7, and then the water pump 13 is turned on to spray water into the cylinder 1 through the water outlet pipe 17, which can avoid damage to the device body due to the overhigh temperature of the inner cylinder 16, thereby increasing the service life of the steam-water separator and quickly cooling the liquid at the bottom of the inner cylinder 16 to avoid the discharged liquid temperature being too high. The liquid level meter 28 can be observed afterwards. When the liquid level at the bottom of the inner cylinder 16 is too high, the solenoid valve 3 12 is opened to discharge the water from the drain pipe 2 11.
