Brief description of the drawings
Fig. 1 is the schematic diagram of steam generator steam-water separator of the present utility model.
Specific embodiment
To enable above-mentioned purpose of the present utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings and tool
Body implementation method is described in further detail to the utility model.
As shown in figure 1, the utility model provides a kind of steam generator steam-water separator, the steam generator is used
Steam-water separator includes lower shell 1, blade assembly 2, newel 3, rising cylinder 4, decline passway 5, water deflector 6 and diffuser 7；
Wherein, the lower shell 1 is located at the bottom of the steam generator steam-water separator.
The blade assembly 2 is arranged in the lower shell 1, and preferably described blade assembly 2 is six helical blades, leaf
Piece curved surface is presented the angle of change, and the curved surface passage of steam circulation is formed between adjacent two blade, and the two ends of blade are respectively with
The cross section of cylinder 1 flushes.
The newel 3 is arranged on the center of the blade assembly 2, it is preferable that the two ends of newel 3 are in elliposoidal, are risen
To the effect of water conservancy diversion and reduction fluid resistance.
It is to rise cylinder 4 in the top of the blade assembly 2, the rising cylinder is provided with weep hole.
The top of the rising cylinder 4 is provided with water deflector 6.Water deflector 6 changes the runner direction of steam, in steam
The step of moisture progress one is separated.
Decline passway 5 is provided with around the rising cylinder 4 and water deflector 6, the decline passway is used to dredge away steaming
The moisture separated in vapour.The moisture for from steam separate enters decline passway 5 by weep hole.Preferably, rising cylinder 4 is
Taper, rise cylinder to design tapered purpose is the separating effect for increasing water droplet.
