Description
Technical field
The utility model relates to Air-Cooling Island technology, particularly a kind of air cooling tubes condenser that can improve cooling effectiveness.
Background technology
Air-Cooling Island is the core component of Direct Air-Cooled Turbo-generator Set, be 2008 from the external new technology introduced, at home 300MW level, 600MW level and 1000MW level Turbo-generator Set are widely applied at present.
This technology uses air as cooling medium, instead of traditional recirculated water and cooling tower, thus reduces recirculated water vaporization loss, saved a large amount of water resources, particularly particularly applicable in the Northwest that water resource is deficienter.
Air-Cooling Island adopts high-order mode of arranging usually, and by by pipeline, the steam-turbine delivered in air cooling tubes condenser is condensed into water, condensate water finally sends back to thermodynamic system of steam tur after treatment.
Fig. 1 is the composition structural representation of existing air cooling tubes condenser, as shown in Figure 1, comprise: steam distribution pipeline (101), three groups of bank of condenser pipes (102) (Fig. 1 is profile, therefore show but one group of bank of condenser pipes) and two condensate-water polishing pipelines (103); Often organize that condenser tube is intrafascicular comprises two symmetrical bank of condenser pipes respectively, one end of two bank of condenser pipes is all connected with steam distribution pipeline, and the other end is connected to different condensate-water polishing pipelines respectively.
Steam distribution pipeline distributes the steam that turbine low pressure cylinder is discharged, and makes steam enter bank of condenser pipes; Vapor stream is through bank of condenser pipes, and done work by the axial flow blower (104) of below, the steam intrafascicular to condenser tube carries out condensation; The water that condensation obtains is collected in the hot well under steam exhaust device of steam turbine by condensate-water polishing pipeline, then sends into thermodynamic system of steam tur by condensate pump.
Although structure shown in Fig. 1 can realize steam cooling (condensation), the service efficiency of air quantity is lower, and then causes cooling effectiveness low.
Utility model content
In view of this, the utility model provides a kind of air cooling tubes condenser that can improve cooling effectiveness, can improve cooling effectiveness.
In order to achieve the above object, the technical solution of the utility model is achieved in that
An air cooling tubes condenser for cooling effectiveness can be improved, comprising: steam distribution pipeline, three groups of bank of condenser pipes and two condensate-water polishing pipelines;
Often organize that condenser tube is intrafascicular comprises two symmetrical bank of condenser pipes respectively, one end of two bank of condenser pipes is all connected with steam distribution pipeline, and the other end is connected to different condensate-water polishing pipelines respectively;
It is characterized in that, be respectively arranged with flow deflector inside each bank of condenser pipes, wherein, inner side refers to the side relative with another bank of condenser pipes in same group.
Visible, adopt scheme described in the utility model, set flow deflector can play the effect of good steady flow condition, thus improves the service efficiency of air quantity, and then improves cooling effectiveness.

Detailed description of the invention
For problems of the prior art, propose the air cooling tubes condenser after a kind of improvement in the utility model, comprising: steam distribution pipeline, three groups of bank of condenser pipes and two condensate-water polishing pipelines.
Often organize that condenser tube is intrafascicular comprises two symmetrical bank of condenser pipes respectively, one end of two bank of condenser pipes is all connected with steam distribution pipeline, and the other end is connected to different condensate-water polishing pipelines respectively; The condensate-water polishing pipeline in the left side shown in Fig. 1 is supposed to be called condensate-water polishing pipeline 1, the condensate-water polishing pipeline on right side is called condensate-water polishing pipeline 2, so, the other end of a bank of condenser pipes is connected to condensate-water polishing pipeline 1, and the other end of another bank of condenser pipes is connected to condensate-water polishing pipeline 2.
Steam distribution pipeline distributes the steam that turbine low pressure cylinder is discharged, and makes steam enter bank of condenser pipes; Vapor stream, through bank of condenser pipes, is done work by the axial flow blower of below, and the steam intrafascicular to condenser tube carries out condensation; The water that condensation obtains is collected in the hot well under steam exhaust device of steam turbine by condensate-water polishing pipeline, then sends into thermodynamic system of steam tur by condensate pump.
With existing air cooling tubes condenser unlike, in air cooling tubes condenser described in the utility model, inside each bank of condenser pipes, be respectively arranged with flow deflector, wherein, inner side refers to the side relative with another bank of condenser pipes in same group.
Accordingly, Fig. 2 is the composition structural representation of air cooling tubes condenser described in the utility model, and preferably, flow deflector (105) is welded on inside bank of condenser pipes.
Fig. 3 is the schematic diagram of flow deflector described in the utility model, and as shown in Figure 3, the concrete size of flow deflector, as arc radius, chord length, thickness etc. all can be decided according to the actual requirements.
In addition, the quantity of the flow deflector that each bank of condenser pipes welds and the particular location of welding also can be decided according to the actual requirements, preferably, the flow deflector that two bank of condenser pipes often in group weld is symmetrical, namely suppose that two bank of condenser pipes in certain group are respectively bank of condenser pipes a and bank of condenser pipes b, bank of condenser pipes a is welded with a flow deflector, so bank of condenser pipes b also will be welded with a flow deflector, and two welding positions of flow deflector on respective bank of condenser pipes are identical.
In actual applications, resistance to " cavitation erosion " property selected usually by flow deflector, the material of good welding performance makes.
In a word, adopt scheme described in the utility model, set flow deflector can play the effect of good steady flow condition, and when there is no flow deflector, flow field flow direction is disorderly, and assignment of traffic is very uneven, and the flow field after flow deflector reorganizes is smooth, thus improve the service efficiency of air quantity, and then improve cooling effectiveness.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
