Description

Technical Field

[0001] The utility model relates to a vacuum steam-water separation device, belonging to the technical field of steam-water separation. Background Art

[0002] At present, there are two main types of steam-water separators on the market. One type uses a cylindrical mesh screen structure, and the other type uses a water-immersion separation structure. Although the circular structure is relatively simple in design and use, the effect is not good, and the mixed steam-water mixture cannot be effectively separated; the water-immersion separation structure requires a water tank to be set up for secondary cooling of the steam-water mixture before discharging, which occupies a large area and is only suitable for large and complex structures, and has high requirements for cooling water temperature. After searching, it was found that the Chinese patent with announcement number CN206853296U disclosed a steam-water separation device. When the steam encounters a baffle device, the flow direction is changed to form an S-shaped flow path. The steam can only pass through the slit-shaped air flow channel. Most of the water is blocked and condensed by the bottom surface of the bottom metal baffle. A small amount of water vapor will be blocked and condensed by the bottom surface of the second metal baffle during the steam rise. Therefore, after the steam is repeatedly blocked and condensed by the multi-layer baffle device, the water in the steam is basically separated by the baffle device to achieve steam-water separation. However, this structure allows the steam-water mixture to directly enter the device for separation, and the steam flow will produce impact and cause noise pollution. Summary of the invention
