Background technology
Occur in nuclear power station under accident conditions, cooling pond is before passive containment thermal conduction system (PCS) puts into operation
Have been heated to a higher temperature or even reach saturation temperature.In order to reach experimental simulation purpose, it is necessary to
Cooling pond is heated to saturation temperature in advance.Widely used method has electrical heating to be heated with steam.For electrical heating method, by
Big, electrically heated rod power limited under rated voltage, it is therefore desirable to install the electrically heated rod of greater number in pond useful load, increases
Big installation workload, while circuit more in pond improves installation difficulty, also bringing potential safety hazard, (aging circuit is broken
Damage causes electric leakage etc.), in addition, greater number of electrically heated rod is installed in many places may increase the flow resistance of cooling water in pond
So as to further have impact on the natural-circulation capacity of cooling water, non-passive safety thermal conduction characteristic is reduced, this is that we strongly keep away
Situation about exempting from.Moreover, lay new supply line and can also experimental cost be greatly increased by purchasing electrically heated rod.Therefore,
Cooling water is heated using steam using existing electric boiler equipment.Conventional steam-heated pipe line, such as a kind of fume afterheat is returned
The system and method (CN102519129A) and a kind of utilization steam for receiving heating chemical tank water heat the dress of cogeneration water
Putting (CN203628618U), often a segment pipe has very long, and integrated degree is high, is not easy to modular repair；By pipeline or heat exchange
Device, which is directly protruding into water tank and is unfavorable for pond, to be heated evenly, especially in the case of the defeated vapour of high pressure, and pond vibration is obvious, security
It is not high.
The content of the invention
The purpose of this utility model is a kind of passive heat derives system cooling pond steam-heating system of offer, with
Overcome deficiencies of the prior art.
To reach above-mentioned purpose, technical solution adopted in the utility model is：
Draw steam pipe all the way in a kind of passive heat derives system cooling pond steam-heating system, the outlet of electric boiler
Line be provided with into cooling pond, on steam pipe line remote controlled aperture enter vapour isolating valve and outlet isolating valve, steam pipe
It is additionally provided with line on thermometer A and thermometer B, steam pipe line and is provided with pressure gauge A and pressure gauge B, is set on steam pipe line
Have and steam (vapor) outlet H type pipelines are provided with flowmeter, cooling pond.
Multiple channel bend is provided with described steam pipe line.
Monitor is provided with described steam pipe line.
The equipment connected on described steam pipe line is connected with flange.
Described steam (vapor) outlet H types pipeline is divided into some widgets using flange and passes through default manhole feeding cooling water
Pond.
Described steam (vapor) outlet H types pipeline is made up of a horizontal connecting tube and two outlet longitudinal tubule (L tubule)s.
A steam (vapor) outlet is respectively arranged after in before each outlet longitudinal tubule (L tubule), each steam (vapor) outlet is provided with vortex steaming
Vapour silencing heater.
Having the beneficial effect that acquired by the utility model：
Pipeline H types are arranged in the pond that the utility model is obtained using electric boiler using segmented conduit and by drag evaluation
Scheme, successfully solves heated inequality, pond vibration problem, while being easily installed, dismantling, repairing, to future heating safety
Shell non-passive safety heat-conducting system (PCS) cooling pond has larger practical significance.The utility model dismounting easy to install, is increased newly
Cost is less, and operation is fairly simple, tests safely controllable, cooling pond is heated evenly, and pond vibration is smaller.

Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, being passive heat derives system cooling pond steam-heating system layout drawing.Electric boiler 1 goes out
That mouthful draws that steam pipe line all the way is provided with remote controlled aperture into cooling pond 11, on steam pipe line enters vapour isolating valve 2
With outlet isolating valve 3, be additionally provided with thermometer A4 on steam pipe line and thermometer B8 carry out measurement temperature, be provided with pressure gauge A5 and
Pressure gauge B7 measures pressure, is provided with flowmeter 6 to measure and multiple pipe is provided with heated in real-time steam flow, steam pipe line
Road elbow 9, to reduce steam pipe line vibration and stress, is also convenient for installing.Be provided with steam pipe line monitor (i.e. camera and
Observation equipment, camera is arranged in cooling pond) monitor the equal usage of equipment connected on cooling pond vibration, steam pipe line
Orchid connection.Steam (vapor) outlet H types pipeline is made up of a horizontal connecting tube 12 and two outlet longitudinal tubule (L tubule)s 13, and in each outlet longitudinal tubule (L tubule)
A steam (vapor) outlet is respectively arranged after in before 13, each steam (vapor) outlet is provided with vortex steam noise reduction heater 10 to reduce
Noise simultaneously can reduce vibration.By steam (vapor) outlet H types pipeline using flange be divided into some widgets by default manhole send into it is cold
But pond 11 and installed according to drawing.
Determined in cooling pond 11 using H types pipeline arrangement, obtained while calculating by drag evaluation and numerical simulation
Corresponding details parameter, the horizontal and vertical cloth of each segment length, caliber and the pipeline of such as H types pipeline in cooling pond 11
Put parameter etc..It ensure that the cooling water in cooling pond 11 can be heated evenly and can reduce the vibration of cooling pond.
Valve bank controls defeated vapour process：Adjusted when using and be used for controlling to add into vapour isolating valve 2 and the outlet aperture of isolating valve 3
Thermal velocity, to reduce the vibration of cooling pond 11 and heating pipeline in heating process, it is ensured that the cooling water energy in cooling pond 11
Enough uniform heating.Before ventilation, close outlet isolating valve 3, it is crack enter vapour isolating valve 2, steaming heating coil passes through thermometer A4, temperature
Meter B8, pressure gauge B7, flowmeter 6 are observed, and when temperature, pressure reaches certain value in pipe, are then turned on exporting isolating valve 3, are on the one hand subtracted
The thermal stress that weak pipeline is subject to, on the other hand prevents that steam meets water condensation formation negative pressure in heating pipe, so that cooling pond
Cooling water suck-back enters jet chimney in 11.Stop first closing outlet isolating valve 3 during ventilation, turn off into vapour isolating valve 2, prevent from steaming
Vapour condensation causes negative pressure in pipeline, so that cooling water suck-back enters in jet chimney in cooling pond 11.
