Description
Technical field
The present invention relates to a kind of turbine condensers to leak online leakage inspection method and device.
Background technique
With utilization of more and more cogenerations of heat and power in chemical industry, in the process of running, due to water quality and other originals
Cause causes condenser leakage phenomenon occur, and condenser also affects boiler water once a leak occurs, not only influence steam turbine vacuum
Water quality, feed-water quality deterioration lead to Steam-water Quality beyond target, and entering boiler for a long time will lead to boiler water wall fouling, generate under dirt
Corrosion, water screen tube bulge, booster, steam quality is bad, into steam turbine, makes steam turbine valve, the serious salt crust of flow passage component,
Not only flow area is reduced, and main inlet throttle-stop valve, timing steam gate incrustation, and the easily bite after removal of load causes unit to exceed the speed limit, similar
The accident country once occurred.Such as outlet, the waste of hot water is not only caused, environment is had an effect on, increased to sewage treatment plant negative
Carry on a shoulder pole
, can be with leak stopping with saw foam bits currently, for the place that turbine condenser leaks frequent occurrence, but pushing away with the time
It moves, condensed water data are higher and higher, seriously affect the safe operation of unit.If needing to stop according to routine maintenance method
Processing carries out leakage detection using condenser full water or other methods, and time-consuming more, leakage detection difficulty is big, parking process, adjusts to production
It has a certain impact, also affects the economical operation of unit, also will cause the insecurity factor occurred during driving and parking, shape
At biggish security risk.
Summary of the invention
The purpose of the present invention is to provide a kind of turbine condensers to leak online leakage inspection method and device, passes through this method
Online leakage detection can be carried out to turbine condenser with device, it is high-efficient without parking, guarantee the safe operation of unit.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of online leakage inspection method of turbine condenser leakage, comprising the following steps:
S1, the leakage side for judging turbine condenser;
S2, the leakage position for determining leakage side;
S3, the manhole door for opening leakage side;
S4, the other end with disposable tablecloth plug leak side copper pipe with respect to manhole door;
S5, point lighted candle make candle flame be located at one end of manhole door close to leakage side copper pipe one by one close to manhole door;
If S6, candle flame are inhaled into, show that corresponding copper pipe has leakage;If candle flame is unchanged, show corresponding
Copper pipe is without leakage;
S7, confirmation have the leak source of leakage copper pipe, block leak source with plug.
The present invention also provides a kind of turbine condensers to leak online leak detection device, including steam turbine condensate collection tank,
Steam turbine condensate collection tank two sides are respectively front water chamber and rear water chamber, and cooling tube, vapour is distributed in steam turbine condensate collection tank
It is equipped with steam inlet, bottom at the top of turbine condensate collection tank and is equipped with steam (vapor) outlet;The front water chamber be equipped with cooling water inlet with
Cooling water outlet, cooling water inlet are equipped with manhole door, the other end with disposable tablecloth plug leak side copper pipe with respect to manhole door.
The beneficial effects of the present invention are:
One, parking process is not had to, unilateral condenser operation does not influence production;
Two, leakage inspection method is simple, reliably, highly-safe;
Three, the repair time is effectively shortened;
Four, it ensure that the safety in maintenance process, many insecurity factors caused by having prevented during startup-shutdown.
Five, the labor intensity for reducing maintenance, reduces environmental risk.
