Abstract
The utility model discloses a hydrophobic recovery box of a steam turbine, which comprises a cylindrical box and a cooling water pipe. The top part of the cylindrical box is provided with an exhaust port; the cooling water pipe is arranged at the lower part of the cylindrical box, and also comprises two spray pipes; the upper part of the cylindrical box is provided whit two parallel through holes; the two spray pipes penetrate through the through holes and are arranged at the upper part of the cylindrical box in parallel; and the pipe walls of the two spray pipes in the cylindrical box are provided with a plurality of spray holes. The hydrophobic recovery box also comprises a filter screen cover which is arranged on the exhaust port at the top of the cylindrical box. The utility model can rapidly cool the steam in the box into condensed water, lead to good cooling effect, reduce the steam leakage, save the energy, and improve the utilization rate of the energy.
Description
Technical field
The utility model relates to the hydrophobic collection box of a kind of steam turbine.
Background technique
The hydrophobic collection box of power plant's steam turbine is used for the hydrophobic recycling of steam turbine.The steam turbine acting needs a large amount of steam, steam all can produce water of condensation when pipeline flows and do work in steam turbine, water of condensation is through chemically treated secondary demineralized water, its water producing cost is higher, if directly externally discharging can cause bigger waste, hydrophobic collection box plays the effect of water of condensation cycling and reutilization.
Steam turbine high pressure steam, low pressure steam pass through the STEAM TRAP of each hydrophobic point with the hydrophobic collection box of hydrophobic introducing, hydrophobic collection box is introduced vapour condenser with all hydrophobic concentrated backs, make and hydrophobicly converge with high pressure, the low pressure steam water of condensation of finishing merit, water of condensation after converging is through condensate pump, be admitted to the boiler heating, form steam acting once more, hydrophobicly in this process, formed cycling and reutilization.
The draining system of steam turbine is because design reasons at present, cause the hydrophobic water that do not condense into fully, contain a large amount of steam in hydrophobic, hydrophobic and residual steam enters the top portion ventilation mouth by hydrophobic collection box of residual steam behind the hydrophobic collection box and leaks in a large number, cause the significant wastage of the energy, the a large amount of dischargings of high-temperature steam cause surrounding plants death, have destroyed environment.
Common hydrophobic collection box bottom is provided with a water-cooling tube cooling water is introduced hydrophobic collection box, cooling water in the water-cooling tube also is through chemically treated secondary demineralized water, its objective is the small amount of steam in hydrophobic is cooled off, because its cooling water access port position is too low, and cooling water can't form vaporific, when a large amount of steam enter hydrophobic collection box, this cooling water effect extreme difference, steam cooling can not be become water of condensation and be reused, cause energy waste.
Summary of the invention
Technical problem to be solved in the utility model provides the hydrophobic collection box of a kind of steam turbine, utilizes this hydrophobic collection box the steam cooling in the casing can be become water of condensation, and good cooling results has reduced the leakage rate of steam, and energy saving improves energy utilization rate.
For solving the problems of the technologies described above, the hydrophobic collection box of the utility model steam turbine, comprise tubular casing, water-cooling tube, described tubular casing top is provided with exhaust port, described water-cooling tube is located at described tubular lower box, also comprises two spraying tubes, and described tubular casing upper parallel has two through holes, described two spraying tubes penetrate the parallel described tubular casing top of being located at of described through hole, and described two spraying tubes have some spray apertures on the tube wall that is positioned at described tubular casing.
The hydrophobic collection box of this steam turbine also comprises screen cover, and described screen cover is located on the exhaust port at described tubular casing top.
Because the hydrophobic collection box of the utility model steam turbine has adopted technique scheme, promptly sets up two spraying tubes in hydrophobic collection box upper parallel, spraying tube is positioned on the hydrophobic collection box tube wall partly and has some spray apertures; This hydrophobic collection box can be cooled to water of condensation fast with the steam in the casing, and good cooling results has reduced the leakage rate of steam, and energy saving improves energy utilization rate.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the front view of the hydrophobic collection box of the utility model steam turbine,
Fig. 2 is that the A-A of Fig. 1 is to view.
Embodiment
As depicted in figs. 1 and 2, the hydrophobic collection box of the utility model steam turbine, comprise tubular casing 1, water-cooling tube 3, described tubular casing 1 top is provided with exhaust port 2, described water-cooling tube 3 is located at described tubular casing 1 bottom, also comprises two spraying tubes 4, and described tubular casing 1 upper parallel has two through holes, described two spraying tubes 4 penetrate parallel described tubular casing 1 top of being located at of described through hole, and described two spraying tubes 4 have some spray apertures on the tube wall that is positioned at described tubular casing 1.
The hydrophobic collection box of this steam turbine also comprises screen cover 5, and described screen cover 5 is located on the exhaust port 2 at described tubular casing 1 top.
The hydrophobic collection box of the utility model steam turbine is set up two spraying tubes in hydrophobic collection box upper parallel, and spraying tube is positioned on the hydrophobic collection box tube wall partly and has some spray apertures; The secondary demineralized water forms water smoke by spraying tube at hydrophobic collection box top, utilize the residual steam in water smoke and the hydrophobic collection box to carry out heat exchange, residual steam is condensed into water, prevent that steam from leaking by the ventilation duct at hydrophobic collection box top, only remedied and be provided with cooling tube and the bad problem of cooling effect at the tubular lower box.And the exhaust port at hydrophobic collection box top installs a screen cover additional, and purpose is to reduce the circulation area of exhaust port, prevents that steam from leaking fast, and another purpose is to prevent that foreign matter from entering hydrophobic collection box, polluted water by ventilated port.After hydrophobic collection box is installed spraying tube, a large amount of steam of hydrophobic collection box inside can condense into water, the steam that leaks by hydrophobic collection box top portion ventilation mouth obviously reduces, and water of condensation enters vapour condenser by hydrophobic collection box, has formed hydrophobic cycling and reutilization.
This hydrophobic collection box can be cooled to water of condensation fast with the steam in the casing, and good cooling results has reduced the leakage rate of steam, and energy saving improves energy utilization rate.
