Specific embodiment
Unless otherwise indicated, term used herein is respectively provided with the conventional implication understanding of those skilled in the art.
To describe the present invention with reference to embodiment and accompanying drawing in detail.
Can achieve packet stable operation helical-tubing steam generator, including cylinder 1, tube sheet 2, low head 3, admission port 4,
Feed pipe 5, spiral heat exchange tube 6, the steam mouth of pipe 7；Described cylinder 1 upper end is connected with tube sheet 2, and tube sheet 2 is provided with admission port
4th, the steam mouth of pipe 7；Cylinder 1 bottom is provided with low head 3, is provided with feed pipe 5, spiral heat exchange tube 6 inside cylinder 1；Described feedwater
Mouth 4 is provided with demarcation strip 8.At least provided with four steam mouths of pipe 7 on described tube sheet 2.Described spiral heat exchange tube 6 includes straight tube
Section and pigtail.Described admission port 4 and feed pipe 5 match.The described steam mouth of pipe 7 and spiral heat exchange tube 6 match.
The operation principle of the present invention：The present invention will feed water from top to bottom vertically to enter by the admission port 4 of tube sheet 2, feed pipe 5
Enter inside the present invention, and through low head 3, after by the Qu Lianjie of low head, distribute the water in spiral heat exchange tube 6, and with
The water of primary Ioops carries out heat exchange, and the steam mouth of pipe 7 that the steam producing after abundant heat exchange passes through on tube sheet enters steam-return line, pushes away
Dynamic steam turbine is done work and is driven electrical power generators.With reference to the accompanying drawings 3, admission port is provided with demarcation strip and main admission port is divided into left and right portion
Point, by adjusting to realize the stable operation under the present invention 50% power to closure about demarcation strip, if do not block can achieve completely
Load power is run.
In the present invention, the arrangement of feedwater, takes full advantage of cylinder 1 inner middle layer space, so that the feedwater of feed pipe 5 is existed
Obtain the preheating of the hot medium of primary Ioops from reactor core and cylinder 1 inwall before flowing to spiral heat exchange tube 6, improve and change
The thermal efficiency, such that it is able to reduce the height of cylinder 1, reduces processing and manufacturing difficulty.Additionally, what spiral heat exchange tube of the present invention was adopted
Big coils structural shape overcomes utilization rate not high defect in gap between middle coil arrangement heat exchanging unit, improves from structure
Heat exchange.Feed pipe 5 is designed to be welded to connect with spiral heat exchange tube 6, cancels feedwater header, steam generator can be made to break down
Need it is only necessary to carry out blocking to admission port 4 and 7 two positions of the steam mouth of pipe during plugging, simplify maintenance operation, safely may be used
Lean on.It is converted into steam in the feedwater having received preheating in feed pipe 5 in spiral heat exchange tube 6 after abundant heating, by main steam
Mouth 7, finally enters steam turbine by steam system pipeline, and driving steam turbine does work, and drives electrical power generators.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
