Abstract
The utility model relates to an exhaust device for direct air-cooling steam turbine in power plant, specifically a device for steam exhaust and vacuum deoxygenation of air-cooling steam turbine. The device comprises a horizontal-type water tank, a steam exhaust pipe arranged inside the water tank, a water reservoir arranged in the lower part inside the water tank, and an exhaust steam inlet arranged on the top of the horizontal-type water tank. The steam exhaust pipe is arranged at 90 degree angle inside the horizontal-type water tank. A steam outlet is arranged on an end socket of the water tank-connecting end of the steam exhaust pipe. A vacuum aspirating hole and a condensed water inlet are welded at one side of the exhaust steam inlet on the top of the horizontal-type water tank. A water replenishing pipe port is welded on the condensed water inlet. A spraying device is arranged below the condensed water inlet. A steam turbine body drain pipe port and a steam turbine body emergency drain pipe port are welded at the other side of the exhaust steam inlet. The utility model integrates the functions of vacuum deoxygenation, collection of normal and emergency drainage water, water replenishment, and recovery and second deoxygenation of drainage water from low-pressure heater.

The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. water storage box; 2. low plus hydrophobic pipe; 3. saddle support; 4. horizontal water tank; 5. steam jet; 6. vacuum extraction opening; 7. the moisturizing mouth of pipe; 8. spraying device; 9. air cooling condenser water of condensation import; 10. steam fairlead; 11. exhaust steam inlet; 12. exhaust steam pipe; 13. the turbine proper water drain mouth of pipe; 14. the hydrophobic mouth of pipe of turbine body accident; 15. steam (vapor) outlet; 16. effluent pipe mouth; 17. dewatering outlet.
Embodiment
Air cooling turbine steam discharge vacuum dust cather of the present utility model is that the water storage box 1 that exhaust steam pipe 12 and bottom installation are installed in horizontal water tank 4 is formed.Above horizontal water tank 4, vapor inlet 11 runs in, exhaust steam pipe 12 curves 90 ° bending in horizontal water tank 4 inside, be connected on the horizontal water tank one end end socket, and do steam (vapor) outlet 15 with end socket welding, upside at horizontal water tank 4, one side of exhaust steam inlet 11, welding vacuum pumping opening 6, welding air cooling condenser water of condensation import 9 is in air cooling condenser water of condensation import 9, the welding moisturizing mouth of pipe 7, spraying device 8 is installed, the opposite side of exhaust steam inlet 11, the welding turbine proper water drain mouth of pipe 13 in air cooling condenser water of condensation import 9 lower ends, the hydrophobic mouth of pipe 14 of turbine body accident.Welding water storage box 1 and two saddle supports 3 below horizontal water tank 4, in a side of water storage box 1, welding low plus hydrophobic pipe 2.Below water storage box 1, welding effluent pipe mouth 16 and dewatering outlet 17.Steam fairlead 10 is installed on exhaust steam pipe 12, is connected with steam jet 5 in the horizontal water tank.
The deoxygenation of air cooling turbine steam discharge vacuum dust cather of the present utility model is achieved like this: need spraying device 8 ejections of the water of deoxygenation from the installation of air cooling condenser water of condensation import 9 lower ends, carry out heat and mass with the steam of steam jet 5 ejections, finish oxygen removal process one time.In water storage box, with the water heat-setting water of low plus hydrophobic pipe ejection, finish the secondary deoxygenation, the dissolved oxygen in water amount is reached below the 15 μ g/L.The water of deoxygenation falls into the water storage box bottom, is discharged by effluent pipe mouth 16.O
2, CO
2Deng incondensable gas, extract out from vacuum pumping opening 6 by vacuum pump, keep the degree of vacuum of horizontal water tank.
