SUMMERY OF THE UTILITY MODEL
The utility model discloses just based on above-mentioned technical problem at least one, provided a terminal cooling device of turboset.
A turboset end cooling apparatus comprising: casing, cryogenic heat exchanger, cold water storage cistern, condenser pipe, the casing front portion is fixed at the end of steam turbine through the clamp, the casing is the cavity casing be equipped with the fan in the casing the fan the place ahead is equipped with a plurality ofly the condenser pipe, the casing bottom is for being equipped with the gas vent still be equipped with the water catch bowl on the shells outer wall, the water inlet of water catch bowl is located the downside of condenser pipe drip department is collected comdenstion water on the condenser pipe, comdenstion water in the water catch bowl enters into through the drain pipe among the cryogenic heat exchanger, cryogenic heat exchanger's cold water outlet with the cold water storage cistern is connected, cryogenic heat exchanger the cold water storage cistern with be cold water circulation between the casing.
Further, the condensation pipe is communicated with the interior of the shell, and cold water in the cold water tank flows in the condensation pipe.
Furthermore, a water outlet pipe on the cold water tank pumps cold water into the shell through a water pump, and the other side of the shell returns to the low-temperature heat exchanger through a water return pipe to exchange heat and change the cold water into cold water.
Further, the diameter of the rear section of the housing is larger than the diameter of the front section of the housing.
Has the advantages that: 1. the utility model adopts the form of the hoop to fix the shell at the tail end of the steam turbine unit, and the installation and the disassembly are all convenient;
2. the cold water circulation is adopted among the low-temperature heat exchanger, the cold water tank and the shell, the auxiliary condensing pipe is used for synchronously cooling and condensing the steam, the condensing efficiency of the steam is accelerated, the condensed water can be refrigerated again and then participates in circulation, and the water resource is saved.
