[0002] Steam-water separators are used for dehumidification of compressed air, dust removal and drying of saturated steam, purification of compressed gas, etc. They are mainly divided into three types: baffle type, adsorption type, and steam cyclone type. They are widely used in various fields. The steam cyclone type uses the mass difference between steam and water droplets to make the steam produce a rotating motion through a specific swirl channel. The water droplets are thrown to the wall under the action of centrifugal force, and then slide down the wall to the bottom of the separator for discharge;

[0003] The traditional cyclone type has an insignificant separation effect when performing water vapor separation, and the separated gas will be accompanied by some water droplets attached to the side walls of the central cylinder cavity when passing through the central cylinder cavity, which will reduce the water vapor separation effect, and scale will form over time, thus affecting the separated water vapor.

[0025] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0026] See also Figure 1-5The utility model provides an embodiment: a steam-water separator, comprising a separator cylinder 10 and a spiral liquid separation component 20, wherein a partition 11 is fixedly connected to the inner cavity side wall of the separator cylinder 10, a top cap 12 is fixedly installed on the upper side of the partition 11, and the spiral liquid separation component 20 is fixedly installed on the lower side end surface of the partition 11, the spiral liquid separation component 20 comprises a connecting plate 21 and a rotating bottom ring 22, the connecting plate 21 is fixedly connected to the partition 11, the rotating bottom ring 22 is rotatably connected to the lower end surface of the connecting plate 21, the lower end surface of the rotating bottom ring 22 is rotatably connected to a liquid separation cylinder 25, and the outer end surface of the liquid separation cylinder 25 is fixedly provided with a spiral Plate 24, fan blade plates 23 are fixedly arranged at an equidistant distribution at the edge of the rotating bottom ring 22, six scraper strips 26 are fixedly connected to the bottom of the center circle of the rotating bottom ring 22 at an equidistant distribution at the edge, each of the scraper strips 26 passes through the central inner cavity of the liquid separator cylinder 25, and fits tightly with the side wall of the central inner cavity of the liquid separator cylinder 25, a liquid separator plate 18 is fixedly installed at the lower side of the liquid separator cylinder 25 in the inner cavity of the separator cylinder 10, and is supported by an installed support frame 17 on the outer end surface of the separator cylinder 10, and a drain pipe 19 is fixedly connected to the bottom of the separator cylinder 10, and the drain pipe 19 is communicated with the bottom of the inner cavity of the separator cylinder 10;

[0027] The water vapor to be separated from the steam is input from the water vapor inlet 14. Since the connection port between the water vapor inlet 14 and the inner cavity of the separator cylinder 10 is tangential to the spiral direction of the spiral plate 24, after the water vapor enters the inner cavity of the separator cylinder 10, it continues to move downward along the spiral flow channel formed between the spiral plate 24, the liquid separator cylinder 25 and the inner cavity side wall of the separator cylinder 10, thereby generating a rotational motion. During the rotation, due to the action of centrifugal force, water droplets in the water vapor are thrown onto the inner cavity side wall of the spiral plate 24 and the separator cylinder 10 and flow from top to bottom into the inner cavity bottom of the separator cylinder 10, thereby achieving preliminary separation of steam and water, and the separated gas is discharged upward at the bottom through the central inner cavity of the liquid separator cylinder 25, thereby entering the top cap 12 for collection and performing secondary separation of the residual condensed water. Separation, and then the separated water vapor is discharged from the steam outlet 13. It should be noted that when water vapor is input from the water vapor inlet 14, the airflow will drive the fan blade 23 to rotate, thereby driving the rotating bottom ring 22 to rotate, and then the scraper 26 rotates along the side wall of the central inner cavity of the liquid separator 25, and the scraper 26 is used to scrape off some water droplets attached to the side wall of the central inner cavity of the liquid separator 25, thereby effectively avoiding the subsequent water vapor rising process. The water droplets retained on the central inner cavity are attached, thereby effectively avoiding the reduction of the water vapor separation effect, and can also avoid the formation of scale on the side wall of the central inner cavity of the liquid separator 25 during long-term use. The separated water can be detected by the liquid level sensor 16 installed on the separator cylinder 10. Once the water level is too high, the water is discharged through the drain pipe 19.

[0028] It is worth mentioning that in the present embodiment, the scraper 26 is arranged in a triangular shape on one end face of the central inner cavity side wall of the liquid separator 25. The triangular end can greatly improve the scraping efficiency of the central inner cavity side wall of the liquid separator 25. At the same time, semicircular protrusions 262 are respectively arranged on the triangular inclined surfaces on both sides. The semicircular protrusions 262 can effectively drain the scraped water droplets, so that the water droplets can fall to the bottom more smoothly. A bayonet portion 261 is fixedly arranged on the bottom end face of the scraper 26, and the bottom end face of the liquid separator 25 is slidably connected to the bayonet portion 261, which can further improve the stability of the scraper 26 during rotation.

[0029] During the specific implementation, the water vapor to be separated from the steam is input from the water vapor inlet 14, so that after the water vapor enters the inner cavity of the separator cylinder 10, it continues to move downward along the spiral flow channel formed between the spiral plate 24, the liquid separator cylinder 25 and the inner cavity side wall of the separator cylinder 10, thereby generating a rotational motion. During the rotation, due to the action of centrifugal force, water droplets in the water vapor are thrown onto the spiral plate 24 and the inner cavity side wall of the separator cylinder 10 and flow from top to bottom into the inner cavity bottom of the separator cylinder 10, thereby realizing the preliminary separation of steam and water, and the separated gas is discharged upward through the central inner cavity of the liquid separator cylinder 25 at the bottom, thereby entering the top cap 12 for collection and performing secondary separation of the retained condensed water, and then the separated water vapor is discharged from the steam outlet 13. It should be noted that when the water vapor is input from the water vapor inlet 14, When entering, the airflow will drive the fan blade 23 to rotate, thereby driving the rotating bottom ring 22 to rotate, and then the scraper 26 will rotate along the side wall of the central inner cavity of the liquid separator 25, and the scraper 26 will be used to scrape off some water droplets attached to the side wall of the central inner cavity of the liquid separator 25, and the semicircular protrusion 262 can effectively drain the scraped water droplets, so that the water droplets can fall to the bottom more smoothly, thereby effectively avoiding the subsequent water vapor rising process will be part of the water droplets left on the central inner cavity attached, thereby effectively avoiding the reduction of the water vapor separation effect, and can also avoid the formation of scale on the side wall of the central inner cavity of the liquid separator 25 during long-term use, and the separated water can be detected by the liquid level sensor 16 installed on the separator cylinder 10, once the water level is too high, the water is discharged through the drain pipe 19.

[0030] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive.
