Description
Technical field
The invention belongs to thermal power plant Turbine Island rubber ball cleaning system for steam condenser technical field, relate to the glueballs recovery system of the condenser cooling water system rubber ball cleaning system of a kind of thermal power plant Turbine Island, particularly a kind of fluid vein dynamic formula junction station.
Background technology
The existing thermal power plant Turbine Island condenser cooling water system overwhelming majority has adopted rubber ball cleaning system, effectively remove heat exchange tube of condenser road inner accompanying impurity and dirt, improve the cleannes of heat exchanger tube inwall, thereby raising heat exchanger effectiveness, ensure that steam turbine can move under best design conditions, improve generatine set heat efficiency, reduce energy loss. Meanwhile, clean in time cooling water pipeline, reduce and prevented the underdeposit corrosion of heat exchange pipeline inwall, extended the service life of heat exchanger tube, the reliability and the security that improve unit.
One of key equipment of rubber ball cleaning system for steam condenser is rubber ball recovery net, and in the present circumstance, what fired power generating unit was most widely used is traditional two mesh-plate structures of arrow type. patent " a kind of two limit self formula ball screens " (patent No. ZL201210272004.6, notification number CN102767988B, day for announcing 2014.09.03), patent " crank connecting rod type ball net drawing device " (patent No. ZL200310114491.4, notification number CN100374809C, day for announcing 2008.03.12) and patent " electric power plant condenser ball purging system " (patent No. ZL201320882135.6, notification number CN203744822U, day for announcing 2014.07.30) be all the arrow type Dual Action mesh-plate structure that adopts counter-flow arrangement, utilize the angle space forming between movable screen and ball screen cylindrical shell to collect glueballs, and discharge glueballs by two glueballs outlets on cylindrical shell, make every effort to improve the rate of recovery and the operational reliability of glueballs. the disclosed system of above-mentioned patent has two glueballs outlets. due to two glueballs introduction pipes at the scene cloth be set up and be difficult to the hydraulic resistance that reaches identical, in the time that waterpower is inhomogeneous, the little side glueballs outlet discharge of hydraulic resistance is large, and opposite side glueballs outlet discharge is little, be easy to cause a side of two glueballs outlets of rubber ball recovery net to stop up glueballs, cause rubber ball cleaning system ball collecting rate obviously to reduce, when the web plate of rubber ball recovery net is opened, glueballs is lost problem.
Summary of the invention
The object of the present invention is to provide a kind of fluid vein dynamic formula junction station, prevent that the glueballs outlet of arrow type double-plate structure ball screen from stopping up glueballs, improve the receipts ball efficiency of arrow type double-plate structure ball screen.
For achieving the above object, the technical scheme that the present invention takes is: a kind of fluid vein dynamic formula junction station, comprise the drive unit setting gradually from top to bottom, the barrel-shaped cylindrical shell of the bearing housing of tubular and opening upwards, cylinder lateral wall is provided with at least two fluid intakes that diameter is identical, and the quantity of fluid intake is even number, the axis of all fluid intakes is all positioned in same level, in bearing housing, be provided with gyroaxis, gyroaxis upper end is connected with the power output shaft of drive unit, revolution shaft lower end stretches in cylindrical shell through bearing housing, and be fixedly connected with flutter valve, gapped between flutter valve and cylindrical shell, the sidewall of flutter valve is provided with the multiple through flow holes with the coaxial setting of fluid intake, the width of through flow hole in the vertical direction is greater than 5～10 millimeters of fluid intake diameters, when use, flutter valve turns to after certain position, one of two fluid intake that are connected with two glueballs outlets of same arrow type double-plate structure ball screen are closed, open for one.
Further, when use, two fluid intakes that are connected with two glueballs outlets of same arrow type double-plate structure ball screen on this pulsating junction station are communicated with these two glueballs outlets respectively by pipeline, on these two pipelines, are separately installed with valve, play buffer action. Meanwhile, in the situation that this pulsating junction station breaks down, can manual operation, alternately make one of them valve closing, another valve open, plays the effect that prevents one-sided stifled ball.
Pulsating junction station of the present invention has the following advantages:
1) simple in structure, easy for installation. According to site space, two outlets of ball screen can be arranged along locus, without deliberately accomplishing how much symmetries of fairlead to junction station.
2) can stop the one-sided stifled ball of arrow type Dual Action mesh-plate structure ball screen glueballs outlet. Replaced and controlled two glueballs outlet uninterrupteds of ball screen by flutter valve, in the time that a side glueballs outlet is blocked by flutter valve, another glueballs outlet is in release position. The large side of hydraulic resistance of having stopped traditional three way type junction station structure formation does not have the phenomenon of current.
3) saving investment and emission reduction effect are obvious. Transform without the rubber ball cleaning system ball screen to traditional, just can improve it and receive ball efficiency. Save investment, reduce the wasting of resources.
