The water chamber shell adopts a conical shell structure, so that the circulating water flow can be further improved, the internal resistance of the water chamber is reduced, and the pressure bearing capacity is increased. The inside no flowing dead zone of hydroecium effectively prevents the rubber ball gathering.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem of uneven flow velocity in the heat exchange tube because the upper and lower part volumes of the existing water chamber are the same, and then providing a trapezoidal water chamber for the large-scale power station condenser.
The technical problem is solved by the following scheme:
the device comprises a trapezoidal conical shell, a top plate, a bottom plate, a circulating water connecting pipe and an air discharging pipe; the top and the bottom opening of trapezoidal awl shell, the top area of trapezoidal awl shell is less than the bottom area, and the top is installed on the top of trapezoidal awl shell, and the bottom plate is installed on the bottom of trapezoidal awl shell, and the circulating water is taken over and is installed on the bottom of bottom plate, and the circulating water is taken over and is set up with the bottom plate intercommunication, and the gas release pipe is vertical to be installed on the top plate, and gas release pipe and top plate intercommunication set up.
Compared with the prior art, the utility model the beneficial effect who contains is:
1. the utility model provides a trapezoidal hydroecium that suits with tube bank shape, the narrow lower extreme in hydroecium upper end is wide, and then the hydroecium upper portion volume is little, the lower part volume is big, can make the intraductal velocity of flow of heat exchange tube upper portion tube group and lower part tube group more even, is favorable to guaranteeing the heat transfer performance of condenser.
2. The water chamber shell adopts a conical shell structure, so that the circulating water flow can be further improved, the internal resistance of the water chamber is reduced, and the pressure bearing capacity is increased. The inside no flowing dead zone of hydroecium effectively prevents the rubber ball gathering.
3. Trapezoidal awl shell make hydroecium shape and tube bank shape suit, further even heat exchange tube inner loop water velocity of flow guarantees condenser heat transfer performance. Meanwhile, compared with the water chamber in the prior art, the trapezoidal water chamber structure is compact in structure, the cost of raw materials can be reduced to a certain degree, and 5-10% of raw materials are saved.
