Description
Technical field
The utility model belongs to generating equipment cooling technology field, relates in particular to a kind of electric power plant condenser ball purging system.
Background technology
Steam turbine exhaust pressure is the key factor that affects unit economy, and in the situation that other condition is constant, the poor direct decision unit exhaust steam pressure of the end of condenser, is operating important monitored parameter.The clean-up performance of Cooling Tubes of Condenser water side is a key factor that affects condenser terminal difference, and it is the effective measures of guaranteeing condenser heat transfer effect in on-line operation, reducing heat transfer end difference for steam condenser that condenser ball cleans.Traditional condenser ball cleaning method and system, as shown in Figure 1, that glueballs in storage spherical tank 11 is sent in condenser water inlet pipe 1, then enter condenser water inlet end hydroecium 3 with current, enter subsequently cooling tube, in condenser water side hydroecium 7, be pooled to outlet pipe 8, finally collected by ball screen 9, return in storage spherical tank 11.But in actual motion, often exist low, the peripheral cooling tube of ball collecting rate to clean and the problem of middle part heat exchanger tube repeated washing, the heat exchange property of condenser and effect do not obtain thorough improvement.
In addition, pitching rate in conventional clean is 7-13%, in actual motion, even if in the situation that ball collecting rate is higher, also have to be equivalent to a part of cooling tube and cannot to be cleaned, that is to say, the cooling tube of considerable part is repeated to have cleaned, part cooling tube does not have glueballs to pass through all the time, cannot be by on-line cleaning, and be the main cause that affects condenser entirety heat transfer property.Trace it to its cause, may follow glueballs flowing velocity and mobile distance dependent.The flow velocity of glueballs in hydroecium is lower than the flow velocity of water, and the cooling tube close to exporting from circulating water inlet is easy to just have glueballs to enter, and need to wait for that away from cooling tube herein glueballs just may have glueballs to enter with water flow to neighbouring.But the water velocity in hydroecium is conventionally well below the glueballs translational speed in cooling tube, in most cases, while first having glueballs in the cooling tube that glueballs enters to leave completely from cooling tube, cooling tube entrance at a distance does not also have glueballs to reach.Glueballs has then entered again cooling tube that existing glueballs leaves.So circulation, far-end cooling tube cannot have glueballs to arrive at all the time, and nature cannot be cleaned.
In recent years, there is concentrated pitching technology, in glueballs cleaning process, pitching rate changes 100% into by the 7-13% of traditional approach, its original intention is to want to ensure that the glueballs quantity dropping into is no less than cooling tube quantity, has glueballs to pass through to every cooling tube, guarantees that every cooling tube is all cleaned.But find in actual motion, cleaning performance is improved to some extent, but in the time that pitching rate reaches Shang Xia 50%, receiving ball speed just no longer increases along with the increase of pitching rate, and this explanation still has part cooling tube not have glueballs to pass through to clean.Except previous reasons, circulating pump lift discharge characteristic variable effect may be Another reason.But 100% concentrates pitching to have equally risk, supposes that ideally all cooling tubes all have glueballs to pass through simultaneously, may form the operation problem that condenser demifacet cleans, if do not reduce load, can bring threat to unit safety.
Therefore propose a kind of glueballs cleaning method and system that improves the actual flushing rate of cooling tube, tool is of great significance.
