Abstract
The invention relates to a steam-water separator, which solves the problem that when a separator of a current nuclear power station set is adopted to complete steam-water separation of circulating steam, the steam-water separation efficiency of the separator is low and water draining is difficult due to an inverse differential pressure opposite to a liquid drop gravity direction caused by a high static pressure at separation plate bottoms; the steam-water separator comprises a groove body, a cover plate, and a plurality of separation plates; the plurality of separation plates are vertically disposed on an upper surface of a bottom plate of the groove body; the cover plate is covered at the upper ends of the plurality of separation plates; the separator also comprises a plurality of water manifolds, and a plurality of end caps with a number equal to the number of the water manifolds; each water manifold has a cylindrical structure; the bottom of each water manifold is connected with one end cap; each through hole on the bottom plate of the groove body is communicated with one water manifold, and the upper end of the water manifold is communicated with each corresponding through hole; facing side walls of each water manifold are provided with two draining through holes, and the two draining through holes are disposed just facing each other. The invention is used for steam-water separation.
Description
Technical field
The present invention relates to a kind of steam-water separator, be specifically related to the steam-water separator that a kind of separator being applied in 1,000,000 nuclear power generating sets is used.
Background technology
In existing nuclear power station separator (MSR) unit, cyclic steam mainly completes carbonated drink separation process at separator.What the water guide mode of existing steam-water separator adopted is the frame mode of opening rectangular opening or circular port in separating plate bottom, and which can not be eliminated the negative effect that contrary pressure reduction brings effectively.As depicted in figs. 1 and 2, in the process separating separator carbonated drink, because the VELOCITY DISTRIBUTION inequality of separating plate entrance causes separating plate inhomogeneous along the static pressure distribution of short transverse, there is high static pressure region in separating plate bottom.And the higher static pressure in separating plate bottom can produce the contrary pressure reduction contrary with drop gravity direction, this pressure reduction can stop drop successfully to flow into guiding gutter, and separating plate bottoms level is raise.In the time that the pressure reduction contrary with drop gravity direction is enough large, separating plate bottoms level can be higher than the height of separator gripper shoe, and overflow causes drop again to be carried by steam, can have a strong impact on like this separative efficiency of separator.Therefore, research and develop a kind of efficient guiding gutter that can eliminate contrary pressure reduction impact and have vital effect for separator.
Summary of the invention
While the object of the invention is to separate for the carbonated drink that solution adopts the separator of existing nuclear power station unit to complete cyclic steam, because the higher static pressure in separating plate bottom can produce the contrary pressure reduction contrary with drop gravity direction, cause the carbonated drink separative efficiency of separator lower, the problem of draining difficulty, and then a kind of steam-water separator is provided.
The present invention addresses the above problem the technical scheme of taking to be: a kind of steam-water separator of the present invention comprises cell body, cover plate and multiple separating plate, multiple separating plates are vertically set on the upper surface of base plate of cell body, cover plate is stamped in the upper end of multiple separating plates, the base plate of cell body has multiple through holes along its length, described separator also comprises multiple aqueducts and the end cap consistent with aqueduct quantity, each described aqueduct is tubular structure, the bottom of each described aqueduct is connected with end cap, the upper end that each through hole on the base plate of cell body is all communicated with an aqueduct and described aqueduct is communicated with respective through hole, in the opposing sidewalls of each described aqueduct, offer two drainage holes, two drainage holes are just to arranging.
The invention has the beneficial effects as follows: aqueduct of the present invention adopts the tubular structure of opposite side perforate, because the position of perforate is just to arranging, on same level position, the air pressure of both sides is cancelled; And having cover plate, aqueduct bottom seals, bottom air pressure can only act on guiding gutter bottom, make like this water droplet fall into through separating plate on the base plate of cell body, through hole on the base plate of cell body and the opening end of guiding gutter enter in guiding gutter inner chamber, make water droplet in aqueduct, can not be subject to the impact of static pressure, the drainage hole by opposite side under the effect of gravity successfully flows out aqueduct.The structure of uniqueness of the present invention can be eliminated the negative effect that contrary pressure reduction brings effectively, can not be subject to the impact of static pressure, ensures that drop successfully flows out from aqueduct.Aqueduct of the present invention has can eliminate contrary pressure reduction impact, and carbonated drink separative efficiency is high, and drainage efficiency is high, draining is unimpeded, simple in structure, is convenient to processing and manufacturing.
