The utility model is described below with reference to specific embodiments. Those skilled in the art can understand that these examples are only used to illustrate the utility model, and they do not limit the scope of the utility model in any way.

It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of this invention. The terminology used in the description of the utility model herein is only for the purpose of describing specific embodiments, and is not intended to limit the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in Figure 1 and Figure 2, a simple device for obtaining dry steam, including a steam separator 1 with an internal cavity design, the upper and lower ends of the steam separator 1 are also provided with upper blocking plates 1A for sealing , the lower blocking plate 1B, the upper blocking plate 1A is provided with a steam inlet 11 and a steam outlet 12, the lower blocking plate 1B is provided with a condensed water outlet 14, and the bottom of the inner cavity of the steam separator 1 is provided with a steam blocking disc 13, The steam disc 13 and the lower blocking plate 1B are connected and supported by a cylindrical support body 131, thereby dividing the inner cavity of the steam separator 1 into an upper cavity and a lower cavity.

Wherein, the steam inlet 11 is connected with a vertical steam pipe 2 for connecting the steam pipe 2 passing out from the boiler room; the steam outlet 12 is connected with a dry steam pipe 3 arranged at right angles for separating the steam separator 1 The dry steam that comes out is transported to the steam-using equipment 4; the condensed water outlet 14 is connected with a vertically arranged condensed water straight-line pipe 15 for discharging the condensed water; the condensed water straight-line pipe 15 communicates with the floor drain device 5, so The condensed water straight discharge pipe 15 is also provided with a branched condensed water recovery pipe 16, which is set in a three-way state with the condensed water straight discharge pipe 15, and the condensed water straight discharge pipe 15 is located below the condensed water recovery pipe 16. There is a direct discharge valve 15a for controlling the flow of condensed water to the floor drain device 5. The condensed water recovery pipe 16 is connected to the drain valve group 15c, and the drain valve group 15c is connected to the drained water pipeline 6 to facilitate back pressure recovery of condensed water.

In this embodiment, the steam separator 1 is a cylindrical body made of DN150-250 carbon steel pipe, and its height is greater than 500mm; Two-thirds, the diameter of the steam-blocking disk 13 is smaller than the diameter of the cylindrical pipe body, the diameter of the steam-blocking disk 13 is larger than the setting distance between the steam inlet 11 and the steam outlet 12, and is close to the inside of the steam separator 1 The pipe wall forms a small gap channel for the condensed water to flow into the lower cavity.

Among them, because the steam sent from the boiler room produces a large amount of condensed water due to the preheating process of the pipeline, after entering the steam separator 1, it will quickly form a water seal in the inner lower chamber of the steam separator 1, and then form a high pressure. area;

After the steam enters the device, due to the larger internal volume, the kinetic energy of the condensed water carried by the steam is reduced, thereby facilitating the collection of the condensed water; when the steam encounters the steam-blocking disc 13, it will quickly flow to the low-pressure area of the steam outlet, and the condensed water will After reaching the steam-blocking disk 13, the condensate will be separated, and the condensed water with reduced kinetic energy will splash on the surrounding tube walls of the steam separator 1, and flow along the inner wall of the carbon steel pipe and the gap between the steam-blocking disk 13 under the action of gravity flow. The small slit channels flow into the lower cavity, so as to obtain the dry steam that can satisfy the steam consumption equipment 4 .

It should be noted that when the condensed water flowing to the lower chamber cannot meet the discharge requirements of the drain valve, open the direct discharge valve 15a until the drain is stable in the sight glass of the trap group 15c, or you can refer to the direct discharge valve. A large amount of steam overflows from the outlet of the condensed water direct discharge pipe 15 to the floor drain, and then close the direct discharge valve 15a to allow the condensed water to be transported to the condensed water pipe 6 through the back pressure of the steam trap group 15c for recycling.

In this embodiment, the steam pipe 2 and the dry steam pipe 3 are provided with a stop valve 15b for controlling the circulation of steam.
