In view of the above-mentioned problems, the problem of the utility model intends to solve is to provide a kind of simple and reasonable, at low cost and divides The high-efficiency steam-water separator good from effect, can effectively ensure that the aridity of steam, ensures the reliability of boiler operatiopn.

In order to achieve the above objectives, the utility model uses following technical scheme：A kind of high-efficiency steam-water separator, including cylinder Body, steam inlet pipe and separator, further include porous plate and baffle, and the cylinder crown center position offers a venthole, institute It states cylinder body bottom centre position and offers a discharge outlet, the cylinder side offers a mounting hole close to bottom position, described One steam inlet pipe for stretching into inner barrel is installed, the shape of the steam inlet pipe is L-shaped, and one end of the steam inlet pipe is stretched in mounting hole Go out outside the cylinder, another end opening is arranged straight up, solid on the openend of the inner barrel on the steam inlet pipe Surely there is a separator, the separator includes central shaft and centrifuge blade, enclosed uniformly along its circumference one on the central shaft The centrifuge blade for being fixed with inclination arrangement, be fixed with porous plate, the porous plate along its circumference one circle on the cylinder inboard wall A cavity is formed between the cylinder inboard wall, a baffle, the baffle and the porous plate are fixed among the porous plate Perpendicular, the baffle is located at the surface of the separator, the vertical range of the porous plate top end face to the baffle Less than or equal to the vertical range of the porous plate bottom face to the baffle.

Preferably, described in vertical range and the porous plate bottom face of the porous plate top end face to the baffle arrive The ratio between vertical range of baffle is 5: 7.

Preferably, the quantity of the centrifuge blade is 6~10.

Effective achievement of the utility model：The utility model is simple and reasonable, at low cost, in use, full containing water It is reached with steam by steam inlet pipe at separator, the saturated vapor containing water generates rotation under the action of centrifuge blade at this time Stream, then generates centrifugal force by eddy flow, so as to which steam and water carried out initial gross separation, while the steam that comes out of initial gross separation with water again It is thrown on the porous plate below baffle and is collided under the influence of centrifugal force, also remnants in which part water and steam Water crush and vaporize when colliding porous plate, greatly improve the aridity of steam, steam dry at this time is behind direction of transferring It is discharged by the porous plate above baffle, and passes through the discharge of the venthole at the top of cylinder, remaining water is then pooled to cylinder body bottom, And it is discharged by discharge outlet.Wherein add porous plate and baffle, and the location arrangements of porous plate and baffle designed, Simultaneously to separator structure in itself and to the relative position relation between separator, steam inlet pipe, porous plate and baffle into It has gone design, has changed the arrangement of total, so as to can twice be separated to steam and water realization, greatly improved separation Effect can effectively ensure that the aridity of steam, ensure the reliability of boiler operatiopn.

In conclusion the utility model has the characteristics that simple and reasonable, at low cost and good separating effect, it can be effective Ensure the aridity of steam, ensure the reliability of boiler operatiopn.
