Abstract
The utility model discloses a condenser is intake and is held little whirlpool guiding device of cambered surface, including little whirlpool guide plate and with the supporting condenser that uses of the little whirlpool guide plate end hydroecium of intaking, little whirlpool guide plate laminate in the condenser end hydroecium of intaking, little whirlpool guide plate is provided with a plurality of water conservancy diversion round hole, the water conservancy diversion round hole with the condenser is intake and is held the condenser inlet tube on the hydroecium to suit, it is protruding to be provided with a plurality of arc water conservancy diversion on little whirlpool guide plate, the arc water conservancy diversion is protruding opposite with water flow direction. Little whirlpool guide plate is polymer resin material guide plate. Intaking the end at the condenser and setting up can effectual the optimizations condenser comdenstion water intake chamber relevant flow field of little whirlpool guiding device, increase the comdenstion water velocity of flow and form the swirling flow in the tube bank entrance, can make the glueballs with higher speed and accurate to get into the tube bank inside, reduce the hydroecium glueballs and stagnate regionally, solved the glueballs and rinsed that to receive the ball rate low, cleaning performance a series of problems such as not good are restrained to the condenser.
Description
Technical field
This utility model relates to rubber ball cleaning system for steam condenser, refers in particular to a kind of micro-whirlpool guiding device of condenser water inlet end cambered surface.
Background technology
Evacuation system for steam condenser is one of coal-burning power plant's core system, and its operational efficiency directly influences steam turbine workmanship efficiency and gross station heat rate.
Rubber ball cleaning system, as cleaning condenser condensed water tube bank, reduces tuze bundle resistance force, the common device of reinforced pipe line dynamic characteristic, is widely used in fields such as China's energy, electric power, chemical industry.The problems such as but rubber ball cleaning system is thrown in after glueballs, the glueballs response rate is relatively low, and part glueballs is enriched in condenser and goes out to hold hydroecium to reclaim, and declines thus result in cleaning performance, condenser condensed water circulation area reduction.Meanwhile, when receiving the work of ball system, condenser outlet section cooling water flow disorder result also in the series of problems such as the internal flow velocity inequality of bank of condenser pipes, the decline of condenser heat exchange efficiency, turbine back pressure rising, coal-burning power plant's decline in benefits.Optimizing flow field, condenser water side, reduce flow disturbance, the correlational study of lifting glueballs utilization ratio integration apparatus does not have yet to be seen.
Utility model content
A kind of micro-whirlpool guiding device of condenser water inlet end cambered surface that the purpose of this utility model is in that to overcome the internal flow velocity of existing bank of condenser pipes uneven and provides.
This utility model realizes by following technical scheme:
The micro-whirlpool guiding device of condenser water inlet end cambered surface, including micro-whirlpool deflector and condenser water inlet end hydroecium matching used with described micro-whirlpool deflector；Described micro-whirlpool deflector fits in described condenser water inlet end hydroecium；
Described micro-whirlpool deflector is provided with several water conservancy diversion circular holes, and described water conservancy diversion circular hole adapts with the condenser water inlet pipe on described condenser water inlet end hydroecium；Being provided with several arc water conservancy diversion on described micro-whirlpool deflector protruding, described arc water conservancy diversion is protruding contrary with water (flow) direction.
Further, described micro-whirlpool deflector is macromolecule resin material deflector.
Yet further, described water conservancy diversion circular-hole internal-wall is provided with swirl type screw thread.
Micro-whirlpool guiding device is set at condenser water inlet end and can effectively optimize the relevant flow field of condenser condensed water intake chamber, increase condensed water flow velocity in tube bank porch and form swirling flow, glueballs can be made to accelerate and accurately enter tube bank inside, reduce hydroecium glueballs stagnant areas, solving rubber ball cleaning ball collecting rate low, bank of condenser pipes cleaning performance is not good waits series of problems.

Fig. 2 is micro-whirlpool deflector structure schematic diagram.
Fig. 3 is micro-whirlpool deflector partial top view.
Fig. 4 is helical form water conservancy diversion circular hole.
In figure: micro-whirlpool deflector 1；Condenser water inlet end hydroecium 2；Helical form water conservancy diversion circular hole 3；Swirl type screw thread 4；Condenser water inlet pipe 5；Clean glueballs 6；Arc water conservancy diversion projection 7.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described in further detail, but this embodiment should not be construed restriction of the present utility model, only for example, simultaneously by illustrating that advantage of the present utility model will become clearer from easy to understand.
The micro-whirlpool guiding device of condenser water inlet end cambered surface, including micro-whirlpool deflector 1 and condenser water inlet end hydroecium 2 matching used with micro-whirlpool deflector 1；Micro-whirlpool deflector 1 fits in condenser water inlet end hydroecium 2；
Micro-whirlpool deflector 1 is provided with several water conservancy diversion circular holes 3, and water conservancy diversion circular hole 3 adapts with the condenser water inlet pipe 5 on condenser water inlet end hydroecium 2, and namely water conservancy diversion circular hole 3 is corresponding with condenser water inlet pipe 5 position, and diameter is identical；Be provided with several arc water conservancy diversion projections 7 on micro-whirlpool deflector 1, arc water conservancy diversion is protruding 7 contrary with water (flow) direction, and this design eliminates condenser intake chamber receipts ball blind area, it is to avoid the situation that cleaning glueballs 6 stops at intake chamber.
Preferably, micro-whirlpool deflector 1 is macromolecule resin material deflector.Water conservancy diversion circular hole 3 inwall is provided with swirl type screw thread 4 so that condensed water accelerates flow through and form whirlpool.
Below do not elaborate and be prior art.
