Abstract
The utility model relates to a leakage monitoring device for a direct inserting type condenser, wherein the lower parts of condenser tubes inside the condenser are provided with a plurality of sample acquisition units disposed parallel to each other. Each sample acquisition unit is composed of a water acquisition barrel, and sampling slots symmetrically arranged on both sides of the water acquisition barrel. The side wall of the water acquisition barrel is provided with overflow orifices and the bottom of the water acquisition barrel is provided with waste discharge holes. The side wall of the water acquisition barrel is also provided with a conductivity electrode. The sampling slots are arranged at an angle of 2-5 degrees relative to the horizontal plane. According to the technical scheme of the utility model, the problem in the prior art that no means is provided for quickly judging the water quality of a condenser can be solved. Due to the adoption of the device, the deterioration condition of the water quality of a condenser can be known first time, and the specific leaky location of the condenser can be quickly judged according to the variation trend of the conductivity. Therefore, the device provides guidance for the subsequent intervening measure.
Description
Technical field
The utility model relates to a kind of direct insertion condenser leakage monitor, particularly relates to a kind of direct insertion condenser leakage monitor that improves plant condenser safe operation technical field.
Background technology
Up to now, condenser leakage monitoring mode is divided two kinds, and a kind of is the inner sampling analysis device of condenser; A kind of is the direct measurement mechanism of condenser main water outlet pipe.
First kind, after condensate water was contaminated, conductivity and sodion can change, but ageing and repeated relatively poor.Principal feature is to take a sample earlier afterwards to chemically examine, and not only link is loaded down with trivial details, process is complicated, and easy omission or flase drop, uses dynamic seal (packing) very easily to destroy the vacuum tightness of condenser, and does not reach real time on-line monitoring truly.
Second kind, current consuming apparatus such as device needing no vacuum pump, motor and solenoid valve.After condensate water is contaminated, can changes to reflect condenser internal leak situation by the indicating value of turbidity sensor, but easily because fluctuation appears in sample water vapor bubbles, fluctuations in discharge, chemical working condition adjustment, cause measurement data unusual; The condenser leakiness can't be judged fast, also the internal leakage point can't be accurately located; Probe easily is corroded and lost efficacy, and carries out maintenance job in uptime inconvenience.
Therefore need badly a kind of direct insertion condenser leakage monitor of realizing real-time monitoring, pinpoint function is provided.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of quick examination condenser and leaks, accurately locatees leakage point, reach the function that the monitoring chilled water leaks, for in time taking counter-measure that foundation is provided, guarantee the direct insertion condenser leakage monitor of unit operation and device security.
For solving the problems of the technologies described above, a kind of direct insertion condenser leakage monitor of the utility model, the below of condenser internal condensation pipe is provided with some sample collection devices in parallel with each other, and sample collection device comprises dust-collecting bucket, and the sampling groove that arranges in the dust-collecting bucket symmetria bilateralis; The dust-collecting bucket sidewall is provided with spout hole, and the dust-collecting bucket bottom is provided with the waste discharge hole; The dust-collecting bucket sidewall is provided with conductivity electrode.
Sampling groove is horizontal by 2 °～5 ° angles.
The diameter in waste discharge hole is 10mm, and the diameter of spout hole is 25mm.
Sample collection device is 4 groups that be arranged in parallel.
Sample collection device is positioned at the position of 0.5 meter of condenser pipe below.
Sample collection device and the welding of condenser inwall are fixing.
Also comprise the hand sampling pipe that extend into from the condenser outside in the dust-collecting bucket.
The utility model has overcome the present situation of the quick judging means shortage of condenser water quality, can determine the situation of condensate water water quality deterioration the very first time, realized judging the particular location that condenser leaks fast by conductivity variations trend, be the target of taking the follow-up operation intervening measure to instruct.
Description of drawings
Fig. 1 is the synoptic diagram of direct insertion condenser leakage monitor provided by the utility model.
Fig. 2 is the synoptic diagram of sample collection device.
Among the figure: 1 is sampling groove, and 2 is dust-collecting bucket, and 3 are the waste discharge hole, and 4 is spout hole, and 5 is conductivity electrode, and 6 is artificial stopple coupon, and 7 is condenser pipe.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
The utility model comprises the sample collection device of being made up of sampling groove 1 and dust-collecting bucket 2, this sample collection device is 4 groups altogether, parallel to each other, evenly be arranged at the position of half meter of multi beam condenser pipe 7 below of condenser inside, sample collection device and the welding of condenser inwall are fixing.
Dust-collecting bucket 2 sidewalls are provided with spout hole 4, and dust-collecting bucket 2 bottoms are provided with waste discharge hole 3; The diameter in waste discharge hole 3 is 10mm, and the diameter of spout hole 4 is 25mm.Impurity flows downstream by waste discharge hole 3 and flows out.
Steam drops to water leg after meeting the cooling water pipe condensation, again from slope current to sampling groove, flowed out by spout hole at last, formed the flow measurement path, guaranteed flowability and the real-time of sample.
The utility model is combined with the conventional jellyfish pipe monitoring device that condenses, and can rapidly, accurately judge Position Approximate and the order of severity of leakage point, provides foundation for taking corresponding counter-measure, instructs fast blockage.The design of the next door of sensor has manual sampling line in water leg simultaneously, but online conductivity table measurement data is verified in the analysis of the draw samples chamber of experimentizing.
Nuclear power station does not also have similarly directly monitoring system at present.Some power station disposes the condenser leakage monitor, but all is condensed water in condenser to be extracted out measure, and then sends into condenser.Because be negative pressure during the condenser operation, cause such system architecture more complicated, difficult in maintenance.
