Description
Technical Field
The utility model belongs to power plant boiler and steam turbine system field, concretely relates to double-flow-path surface condenser rubber ball cleaning system for optimizing goal.
Background
The condenser is a heat exchanger for condensing the exhaust steam of the steam turbine into water. The condenser is mainly used in a steam turbine power device and is divided into a water-cooling condenser and an air-cooling condenser. The condensing equipment plays a role of a cold source in the thermodynamic cycle of the steam turbine device. The exhaust temperature and the exhaust pressure of the steam turbine are reduced, and the thermal cycle efficiency can be improved. The condenser has the main functions of establishing and maintaining high vacuum at the steam exhaust port of the steam turbine and forming a complete cycle by using water condensed from the steam exhaust of the steam turbine as boiler feed water. And the condenser keeps higher vacuum degree through exchanging heat with circulating water.
The different condensers according to the steam condensation mode can be divided into a surface type (also called dividing wall type) and a mixed type (also called contact type). In a surface condenser, steam separated from a cooling medium is condensed into liquid on a cooling wall surface (usually, a metal pipe). The cooling medium may be water or air. The water-cooled surface condenser is divided into a single-flow path condenser and a double-flow path condenser according to the flowing mode of cooling water. The water-cooled surface condenser mainly comprises a shell, a tube bundle, a water chamber and the like. The exhaust steam of the steam turbine enters the shell through the throat part, is condensed into water on the cooling pipe bundle and is collected in the hot well, and is pumped out by the condensate pump. Cooling water (also called circulating water) enters the cooling tube bundle from the inlet water chamber and is discharged from the outlet water chamber. In order to ensure that high vacuum and good heat transfer effect are maintained in the condenser when steam is condensed, the condenser is also provided with air extraction equipment which continuously extracts air and other non-condensed gases which leak into the condenser. The air extraction equipment mainly comprises a water jet air extractor, a steam jet air extractor, a mechanical vacuum pump, a combined vacuum pump and the like.
The cleanness degree of a heat exchange tube bundle of the condenser has an important influence on heat transfer, and after dirt is formed in the heat exchange tube, the flow resistance and the thermal resistance of fluid can be increased, so that the heat transfer performance of the heat exchange tube bundle is influenced. The rubber ball online cleaning system is a condenser cleaning technology which is widely used at present, dirt in the heat exchange tube bundle can be cleaned online under the condition of no shutdown, labor cost is saved, and the service life of the heat exchange tube bundle can be prolonged. However, in actual operation, because the inlet water chamber and the rotary water chamber of the double-flow-path surface water-cooling condenser have flow field dead zones, the rubber balls are difficult to enter the heat exchange tube bundle near the dead zones, and therefore the heat exchange tube bundle at the dead zones can not be cleaned, the cleanliness of the heat exchange tube bundle is seriously influenced, the heat transfer efficiency of the heat exchange tube bundle is influenced, and the economical efficiency of the operation of the condenser is influenced.
