In figure: the 1-condenser water box; The 2-Three-way sight glass; The 3-ball collector; The 4-Rubber ball pump; The 5-ball screen.6-ball screen plate; 7-condenser Discharging bent-tube section; The 8-deflector; 9-tests pipeline; The 10-butterfly valve; The 11-deflection plate; 12-condenser water inlet pipe; The 13-deflection plate; The 14-ball valve.
The specific embodiment
Embodiment, as shown in Figure 1, a kind of rubber ball cleaning system for steam condenser, comprise condenser water box 1, the bottom of described condenser water box 1 is symmetrically installed with two condenser water inlet pipes 12, the left and right sides of described condenser water box 1 is separately installed with condenser outlet pipe 15, on described condenser outlet pipe 15, be separately installed with ball screen 5, between two ball screens 5, pass through pipeline connection, on the pipeline between two ball screens 5, be communicated with ball collector 3, described ball collector 3 is communicated with respectively with two condenser water inlet pipes 12 by pipeline.
On connecting pipeline between described ball collector 3 and two condenser water inlet pipes 12, Three-way sight glass 2 is installed, is convenient to observe glueballs ruuning situation.Described Three-way sight glass 2 is communicated with respectively with two condenser water inlet pipes 12, on the connecting pipeline between Three-way sight glass 2 and two condenser water inlet pipes 12, is separately installed with ball valve 14.
On connecting pipeline between described ball collector 3 and two ball screens 5, Rubber ball pump 4 is installed.
On described ball collector 3 and condenser outlet pipe 15, be positioned at condenser Discharging bent-tube section 7 position before and be communicated with ancillary test pipeline 9, on test pipeline 9, butterfly valve 10 is installed.
After setting up test pipeline 9, rubber ball system can directly carry out partial circulating pitching operation through ball screen by the condenser short circuit, thereby condenser problem and ball screen plate problem are divided into two.As undesired as the ball screen partial circulating, must at first solve ball screen jumping ball, long-pending ball problem; As normal as the ball screen partial circulation operation, and, by the full circulation operation existing problems of condenser, should consider glueballs type selecting again, or by rectifying and improving the condenser dead band to improve running effect.
As shown in Figure 2, ball screen plate 6 is installed in ball screen 5, the downside of described ball screen plate 6 is connected with deflector 8, and described deflector 8 is two, is " eight " set up of character patt ern.
Desirable diversion component, should be able to appropriate area form turbulent flow on ball screen plate 6, make glueballs smooth and easy through-flow under main current.Otherwise flow field can not get improving, and glueballs easily is deposited in ball screen plate 6 one sides, causes long-time receipts not return glueballs.Therefore join deflector 8, be soldered on the housing appropriate location.The installation of deflector 8 makes to receive ball mouth upper area and forms turbulent flow, avoids amassing ball on the net.
The corner of described condenser outlet pipe 15 has condenser Discharging bent-tube section 7, in condenser Discharging bent-tube section 7 inside, is provided with a deflection plate 11 identical with the crooked radian of condenser Discharging bent-tube section 7.
Generally speaking, should there be the straight length that is equivalent to 3 times of diameter left and right distances in the upstream of ball screen plate installation site and downstream, and be even to guarantee the pipeline flow field, is convenient to the normal operation of ball screen plate.But actual conditions ball screen plate upper end often are bend loss, and lower end is bend loss or butterfly valve, sometimes have a strong impact on the work of ball screen plate.By at the interior increase deflection plate 11 of condenser Discharging bent-tube section 7, recirculated water is divided into two, adjust fluid flow fields, make to manage interior velocity of medium and be tending towards evenly, thereby steady flow condition can work the ball screen plate.
As shown in Figure 3, the interior position near being communicated with condenser water inlet pipe 12 of described condenser water box 1 is provided with deflection plate 13.
Glueballs circulatory system flow field problem has a strong impact on the normal input of glueballs, and the existence of dead band, whirlpool is trapped in condenser water box 1 glueballs that hygrometric state density is less.Recirculated water flows to the condenser water box 1 of cross section sudden enlargement from condenser water inlet pipe 12.Because fluid particle has inertia, the movement locus of fluid particle can not enlarge according to the shape sudden turn of pipeline, be that whole fluid can only continue to flow forward after leaving condenser water inlet pipe 12, enlarge gradually, at tube wall corner fluid and tube wall, break away from formation whirlpool district like this.The flow direction of the outside, whirlpool district fluid particle and the flow direction of main flow are inconsistent, form gyration.The part glueballs can be assembled in a large number in the whirlpool district like this, has a strong impact on the normal operation of system.The setting of deflection plate 13 can well overcome the above problems.
