Firstly, when a large amount of steam containing water enters the steam-water separator, if the rate is too fast, it is very easy for a large amount of steam to directly discharge through the drain pipe. Secondly, the setting of a single baffle is very likely to result in incomplete steam-water separation, and there is still a small amount of water in the gas discharged from the exhaust pipe.
[0003] In view of this, there is an urgent need to solve the above problems of a steam-water separator. Content of the Utility Model

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0021] Embodiment 1
[0022] Please refer to the attached Figure 1, a steam separator, comprising:
[0023] an upper housing 1, a lower housing 2, a feed pipe 3, a drain pipe 4 and a conical exhaust baffle 5. A first flange 10 is provided on the upper housing 1, and a second flange 20 is provided on the lower housing 2. A plurality of mounting holes 11 with matching positions are provided on the first flange 10 and the second flange 20. Bolts 12 matching the mounting holes 11 are provided in the mounting holes 11. The feed pipe 3 passes through the side wall of the upper housing 1 and is fixedly connected thereto. The conical exhaust baffle 5 is located inside the upper housing 1 and is fixedly connected to the top wall of the upper housing 1. The drain pipe 4 is fixedly connected to the bottom wall of the lower housing 2.
[0024] Specifically, the vertical position of the feed pipe 4 is higher than the vertical position of the lower end of the conical exhaust baffle 5;
[0025] When the steam with moisture is sprayed into the upper housing 1 through the feed pipe 3, it first contacts the conical exhaust baffle 5, forms condensation, and slides downward along the side wall of the conical exhaust baffle 5, directly falling into the lower housing 2 and being discharged through the drain pipe 4. It should be noted that, in order to facilitate the cleaning of the lower housing 2 and considering that according to different actual situations, it may be necessary to replace the conical exhaust baffle 5 with a spiral air guide assembly, the upper housing 1 and the lower housing 2 are connected by the first flange 10 and the second flange 20. Therefore, a waterproof ring is provided at the connection of the first flange 10 and the second flange 20.
[0026] Embodiment Two
[0027] Please refer to the appendix Figure 2
[0028] A plurality of second baffles 50 which are alternately arranged and inclined are provided on the inner wall of the conical exhaust baffle 5. One end of the second baffle 50 close to the air inlet of the conical exhaust baffle 5 is fixedly connected to the inner wall of the conical exhaust baffle 5, and one end of the second baffle 50 close to the air outlet of the conical exhaust baffle 5 does not contact the conical exhaust baffle 5;
[0029] Considering that there may be an incomplete steam-water separation when using a single conical exhaust baffle 5, in order to avoid moisture in the discharged gas, a plurality of second baffles 50 which are inclinedly installed are provided inside the single conical exhaust baffle 5 to perform a second separation of the steam, so that the possible moisture condenses and falls on the second baffles 50.
[0030] Embodiment Three
[0031] Please refer to the appendix Figure 3
[0032] The lower housing 2 is provided with a drainage assembly 6. The drainage assembly 6 includes an outer drainage pipe 60 and an inner drainage pipe 61. The outer drainage pipe 60 is fixedly connected to the bottom wall of the lower housing 2, its top is closed, and a plurality of water-passing round holes 600 are provided on its side wall. The upper end of the inner drainage pipe 61 is located inside the outer drainage pipe 60, and its lower end passes through the lower housing 2 and is fixedly connected to the lower housing 2.
[0033] Specifically, the vertical height of the upper end of the inner drainage pipe 61 is higher than the vertical height of the water-passing round holes 600.
[0034] Considering that there may be a problem that the condensation water discharge rate of the existing drainage pipe 4 is greater than the water condensation rate. While this problem exists, if the feeding rate of the feeding pipe 3 is relatively large, steam containing moisture will directly discharge from the drainage pipe 4.
[0035] Therefore, the outer drainage pipe 60 is arranged to cover the inner drainage pipe 61, and by setting the position of the water inlet at the upper end of the inner drainage pipe 61 higher than that of the water-passing round holes 600, the purpose is achieved that the condensation water in the lower housing 2 cannot be completely emptied. When there is condensation water in the lower housing 2, steam containing moisture cannot directly discharge through the inner drainage pipe 61. At the same time, this method can further precipitate the condensation water and precipitate the impurities that may be contained in the condensation water.
[0036] Embodiment 4
[0037] Please refer to the appendix Figure 4
[0038] The drainage pipe 4 is provided with a drainage assembly 6. The drainage assembly 6 includes an outer sleeve 62, an inner sleeve 63 and a floating block 64. The inner sleeve 63 is fixedly connected to the bottom of the lower housing 2. The outer sleeve 62 is sleeved on the inner sleeve 63, and a plurality of inner water-passing holes 630 are provided on the side wall of the inner sleeve 63. Outer water-passing holes 620 matching the inner water-passing holes 630 are provided on the side wall at the lower end of the outer sleeve 62. The floating block 64 is fixedly connected to the top wall of the outer sleeve 62.
[0039] Specifically, the floating block 64 is provided with at least one set of position-limiting rods 640 slidably connected thereto, and the position-limiting rods 640 are fixedly connected to the bottom wall of the lower housing 2.
[0040] Considering the following problems that may exist in practical applications, when the rate of water condensation is greater than the drainage rate of the drain pipe, the condensed water in the lower housing 2 will accumulate more and more. When the liquid level reaches a certain height, it will directly affect the effect of steam-water separation. Therefore, the outer sleeve 62 and the inner sleeve 63 are provided. When the outer sleeve 62 is in different positions, the reagent water holes formed by the intersection of the outer water holes 620 provided thereon and the inner water holes 630 on the inner sleeve 63 have different diameters, thereby achieving the purpose of controlling the drainage rate. At the same time, in order to enable the outer sleeve 62 to change its position with the water level, the floating block 64 is fixed to the outer sleeve 62. At the same time, in order to prevent the outer sleeve 62 from rotating, resulting in the situation where the outer water holes 620 and the inner water holes 630 cannot intersect with each other, a position limiting rod 640 is provided for position calibration;
[0041] It should be noted that the floating block 64 is not necessarily fixed to the top of the outer sleeve 62, and can also be fixedly connected to the side wall of the outer sleeve 62, and the specific position is determined according to the actual situation.
[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
