[0039] like Figure 1-3 As shown, an embodiment of the present application discloses a steam-water separator, including a shell, a cyclone inlet 2 and a separation component. The shell is provided with an air outlet and a liquid discharge port 111, and the air outlet is used to discharge the separated dry steam. The liquid discharge port 111 is used to discharge the separated liquid. The cyclone inlet 2 is fixedly assembled on the shell, used for the input of steam and water, and performs the initial centrifugal separation of steam and water. The separation component is fixedly assembled in the shell, one end of the cyclone inlet 2 is located outside the shell, and the other end corresponds to the separation component, which is used to separate the steam and water entering the shell again.

[0040] By arranging a cyclone inlet 2 on the shell and cooperating with a separation component arranged in the shell, the incoming steam and water can be separated multiple times, the separation effect is better, the dryness of the steam can reach 99.9%, and the reliability is high.

[0041] In this embodiment, a drain pipe is fixedly assembled at the drain port 111 through a gasket and a flange, and a valve is installed on the drain pipe for discharging water in the separator after a period of time, which is beneficial to improving the steam-water separation effect in the shell.

[0042] In this embodiment, the valve may be a ball valve, a butterfly valve, or a solenoid valve, and a suitable valve may be selected according to actual conditions.

[0043] In some embodiments, Figure 1 As shown, the shell includes a first shell 11, a second shell 12 and a support ring 112. The cyclone inlet 2 is fixedly mounted on the first shell 11 for inputting soda and water. The air outlet is arranged on the second shell 12 for discharging the dry steam after separation. An air outlet flange 121 is integrally formed at one end of the air outlet, and a first interface 122 is fixedly mounted on the air outlet plate by bolts for fixed connection with other equipment. The liquid drain port 111 is arranged on the first shell 11 for discharging the liquid formed after separation. The support ring 112 is fixedly arranged on the inner wall of the first shell 11, and one end of the separation component is connected to the support ring 112, which is used to provide an assembly basis for the separation component, and separates the first shell 11 into two cavities together with the separation component.

[0044] In this embodiment, the connection between the first shell 11 and the second shell 12 is formed with a first connection flange 110 and a second connection flange 120 by integral casting, respectively, for fixedly connecting the first shell 11 and the second shell 12. In order to enhance the sealing performance of the connection between the first shell 11 and the second shell 12, a sealing ring is provided at the connection between the first shell 11 and the second shell 12. In order to facilitate the installation of the separation component, an annular notch is provided on the first shell 11 and / or the second shell 12.

[0045] In this embodiment, if Figure 1 and 3 As shown, in order to facilitate the assembly of the steam-water separator and other equipment, a plurality of brackets 4, preferably three, are arranged at equal angles on the outside of the bottom of the first shell 11, and a threaded hole is provided at the bottom of each bracket 4.

[0046] In some embodiments, Figure 1-2 As shown, the cyclone inlet 2 includes a cyclone body 21 and a second interface 22. The cyclone body 21 has a plurality of rotating cavities, preferably three rotating cavities, which are spirally connected to provide centrifugal separation force when the soda enters, thereby performing a primary separation on the entering soda. The outlet of the rotating cavity corresponds to the separation component, which is used to connect the soda after centrifugal separation with the separation component and perform a second separation. The second interface 22 is fixedly connected to the inlet of the cyclone body 21 by bolts for connecting to the outside world.

[0047] In this embodiment, the swirl body 21, the first shell 11 and the second shell 12 are all integrally cast by a hemispherical casting process. On the one hand, it can ensure high structural strength and reliability and reduce the wall thickness of the sphere; on the other hand, it can also reduce manufacturing costs.

[0048] In some embodiments, Figure 1 As shown, the separation assembly includes a mounting frame 3, a sleeve 31, a first separation member, and a second separation member. The mounting frame 3 is clamped and installed at the annular notch of the first shell 11 and the second shell 12. One end of the sleeve 31 is fixedly assembled on the mounting frame 3 by bolts, and the other end is connected to the support ring 112, and a gap is formed. The outlet of the rotating cavity corresponds to the outer wall of the sleeve 31, so that the steam after the first separation through the rotating cavity contacts the outer wall of the sleeve 31 again, forming a second separation, and the steam separated for the second time can pass through the gap to the bottom side of the sleeve 31, so that the steam separated for the second time can enter the first separation member for the third separation. The first separation member and the second separation member are both arranged in the sleeve 31 and are arranged relative to each other, so that the steam passing through the first separation member passes through the second separation member again to form a fourth separation, so that the dryness of the steam can reach 99.9%.

[0049] In this embodiment, the first separation element includes a conical frame 32 and a separation leaf 33. The conical frame 32 is fixedly arranged in the sleeve 31, and there is a gap between the top of the conical frame 32 and the inner wall of the sleeve 31. The separation leaf 33 is spirally arranged on the outer wall of the conical frame 32, so that the steam after the second separation contacts the spiral leaf, and the steam enters the second separation element through the gap, and the liquid falls along the conical frame 32 and then falls into the discharge port 111.

[0050] In one embodiment, the separation blades 33 are integral and sheet-shaped and are spirally arranged on the conical frame 32, so that the closer the top of the separation blades 33 is to the inner wall of the sleeve 31, the smaller the distance between the top and the inner wall of the sleeve 31 is, so that when the soda and water come into contact with the blades, a stronger separation effect is formed.

[0051] In another embodiment, a plurality of separation leaves 33 are provided, and the plurality of separation leaves 33 are spirally arranged at equal intervals on the conical frame 32, so that the distance between the top of the separation leaf 33 closer to the inner wall of the sleeve 31 and the inner wall of the sleeve 31 is smaller, so that after the soda and the separation leaves 33 come into contact, the water is easier to fall.

[0052] In some embodiments, Figure 1As shown, the second separation element includes a filter screen 35 and a baffle 34. The baffle 34 is fixedly arranged in the sleeve 31, and a gap is formed between the baffle 34 and the inner wall of the sleeve 31, so that the soda water separated for the third time by the first separation element can enter the cavity between the filter screen 35 and the sleeve 31, and then enter the filter screen 35 for the fourth separation. One end of the filter screen 35 is fixedly connected to the baffle 34, and the other end is fixedly connected to the mounting frame 3, so as to stably install the filter screen 35 in the sleeve 31.

[0053] In some embodiments, the cone frame 32 is fixed on the baffle 34 by bolts, so that the installation of the cone frame 32 is more convenient.

[0054] In this embodiment, the filter screen 35 is an annular filter screen 35 that has been treated by a nitriding process. The filter screen 35 treated by a nitriding process can improve the surface hardness and rust prevention effect of the filter screen 35, and at the same time improve the resistance of the surface of the filter screen 35 to water vapor erosion, thereby extending the service life of the filter screen 35, and further extending the service life of the steam-water separator. In this embodiment, the nitriding process for treating the filter screen 35 is an existing process and will not be described in detail here.
