Abstract
Provided is a step type separating board device for a reverted high-pressure feed-water heater of a large nuclear power station. The upper level of the high-pressure feed-water heater of the nuclear power station has a big water-delivery flow and low pressure, the flash steam flow of the next level of stream is big, and heated wet steam pumped out is big in volume, thereby causing the fact that the whole condensing section has excessive steam, especially the reverted structure is easy to cause a heat exchange tube to be impacted. The step type separating board device comprises an outer casing (19) and the heat exchange tube (2) in the outer casing. The upper ends of supporting tubes are connected to a tube plate, and the heat exchange tube is installed on the tube plate. Operating exhaust pipes (20) and the supporting tubes penetrate through an upper coaming board (3), a lower coaming board (3), an upper separating board (5), a middle separating board (6), a lower separating board (7) and a bottom separating board (8) in order. Spacer pipes (16) are installed on the outsides of the supporting tubes in sleeving mode between each separating board. A steam inlet pipe (17) is installed on one side of the outer casing, and a water outlet pipe (18) is arranged at the lower end on one side of the outer casing. The step type separating board device is used for the reverted high-pressure feed-water heater of the large nuclear power station.
Description
Technical field
The utility model relates to a kind of device of large nuclear-power inversion type high-pressure feed-water heater; Be specifically related to a kind of large nuclear-power inversion type high-pressure feed-water heater staged baffle plate device.
Background technology
The hydrophobic flow of the higher level of nuclear power station high-pressure feed-water heater is big, and pressure is lower, and is bigger to next stage dewatering capacity-enlarging quantity of steam, and the heating moist steam amount of taking out is big, cause the whole section of condensing quantity of steam excessive, therefore easy impingement heat transfer pipe especially is inverted vertical structure.The hydrophobic inlet of high-pressure heater higher level adopts usually and over against the hydrophobic porch of higher level impingement baffle is being set at present, the hydrophobic baffle plate that directly impacts, and baffle plate is washed out easily, the heat exchanger tube that impacts, and this kind structure causes water-level fluctuation easily.
Conventional inverted height adds that the section of condensing dividing plate adopts is arrangement with a kind of physical dimension, because that height adds tube bank is higher, causes the condensate water drop of generation bigger easily, impact bigger to Normal Water Surface, cause water-level fluctuation easily, and the water seal of the dirty formation waterfall of water level, heat transfer property influenced.
Summary of the invention
The purpose of this utility model provides a kind of staged baffle arrangement structure, and offers groove on dividing plate, prevents water-level fluctuation, and the large nuclear-power inversion type high-pressure feed-water heater staged baffle plate device that vapour, liquid are separated.The utility model adopts big hydrophobic chamber gathering-device structure, collects hydrophobic that the higher level comes.
Above-mentioned purpose realizes by following technical scheme:
A kind of large nuclear-power inversion type high-pressure feed-water heater staged baffle plate device, its composition comprises: overcoat and heat exchanger tube wherein thereof, the stay pipe upper end connects tube sheet, described heat exchanger tube is housed on the described tube sheet, operation blast pipe and described stay pipe pass coaming plate, following coaming plate, upper spacer, median septum, lower clapboard, base spacer in turn, the described stay pipe outside between each dividing plate is set with distance sink tube, described overcoat one side is equipped with steam inlet tube, and the water delivery outlet is equipped with in described overcoat one side lower end.
Described large nuclear-power inversion type high-pressure feed-water heater staged baffle plate device, between described upper spacer and described median septum, median septum is housed, first central dividing plate and second central dividing plate are housed between described median septum and described lower clapboard in turn, the 3rd central dividing plate and the 4th central dividing plate are housed between described lower clapboard and described base spacer, and gas block panel is equipped with in described steam inlet tube position.
Described large nuclear-power inversion type high-pressure feed-water heater staged baffle plate device, all have waist-shaped hole or U type groove at described upper spacer, on described on the median septum, described first central dividing plate, described second central dividing plate, described lower clapboard, described the 3rd central dividing plate, described the 4th central dividing plate, and breach successively reduces from top to bottom, the dividing plate top of the section of condensing is provided with carbonated drink and separates coaming plate, is provided with coaming plate below the dividing plate of the section of condensing.
Beneficial effect:
1. height of the present utility model adds the section of condensing dividing plate and adopts stagger, and the potential energy of the water that making condenses gets off can obtain discharging step by step, and drop is diminished.
The utility model is provided with carbonated drink and separates the coaming plate structure above the section of condensing dividing plate, thus below the section of condensing dividing plate, be provided with coaming plate given the flow direction of condensate water, to prevent the steam and water bursting phenomenon.
The utility model is that dividing plate adopts stagger, and breach successively reduces from top to bottom, makes condensate water fall to playing the effect of a buffer platform, reduces the potential energy that current fall, and reduces the impact of falling water flow to water level, avoids water-level fluctuation.The utility model upper spacer, median septum, on median septum, first central dividing plate, second central dividing plate, lower clapboard, the 3rd central dividing plate, the 4th central dividing plate all have waist-shaped hole or U type groove, make vapour, the separately anti-dirty hydrophobic formation waterfall of the side water seal here of water, cause the heat exchange dead band, influence heat exchange efficiency.
The utility model is to establish three cofferdam on the dividing plate, make condensate water along under the effluent, steam three flows towards the heart from other, avoid the globule collision of the steam that rises and whereabouts, on dividing plate, offer different mounting holes and groove, cause to fall and break and hydrophobicly fall into strips, steam can enter from gap location, avoid current to form waterfall and cause water seal, form the heat exchange dead band, influence heat-transfer effect.
