High water level.Between maintenance with pump house be staggered floor arrange, significantly reduce civilwork engineering quantity.Pump house operates layer absolute altitude according to water pump
The depth requirements that absorb water determine, lower than layer absolute altitude is operated between water storage, it is shorter to follow pump pump shaft, follow pump operation safety and stability and equipment manufacturing cost
It is lower.
3, recirculated water channel improves cooling tower ring group stability from receiving in water tower ring group across herringbone column in cooling tower works.Ditch
Road is half ground level arrangement, and civil engineering excavated volume is lower.Recirculated water channel is single hole, the flaring planaperturate at flat bank arc
Diameter, water flow are level stream, and the corner of no vertical direction, hydraulic flow state is preferable, and hydraulic resistance is small, reduce and follow pump power consumption.
4, diffuser is arranged reasonable diffusion angle, setting diversion pier and water conservancy diversion partition wall in diffuser, diffuser and follows pump house
Joining section effectively intakes height lower than diffuser starting point height, this kind of diffuser arrangement even water distribution, waterpower resistance between water inlet
Power is small, and flow-shape is stablized.
5, pump house is indoor arrangement, is outdoor arrangement between water storage, is ensuring key equipment (water circulating pump) good fortune
Under the premise of row environment, control engineering cost.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the cross-sectional view in the face A-A of structural schematic diagram of the invention.
Attached meaning marked in the figure is as follows: 1, water tower is received, between 2, maintenance, and 3, pump house, 4, water pump, 5, flume, 6, expansion
Dissipate road, 7, angle of flare, 8, diversion pier, 9, water conservancy diversion partition wall, 10, ring group, 11, catch basin, 12, herringbone column.
Specific embodiment
Specific introduce is made to the present invention below in conjunction with the drawings and specific embodiments.
Channel of the invention, including flume and diffused channel are industry slang, are enclosed water tubulose.
By taking the second stage of (2 × 1000MW) engineering in the Jurong Hua electricity, Jiangsu as an example, the present invention will be further explained.
The Jiangsu Jurong Hua electricity the second stage of the project builds 2 × 1000MW thermal power generation unit, and water system is expanded using secondary cycle
Big unit system, every unit circulating cooling water is about 25m3/ s, every unit set 1 drenching area as 11000m2High-order receive
Water tower, 3 water circulating pumps；2 units build a pump house jointly.
Step 1: water circulating pump type is determined.
By manufacturing ability, the correlation of analyzing all kinds of water circulating pumps (vertical mixed flow pump, volute pump, centrifugal pump of horizontal axis)
Achievement, pump efficiency, operation stability, shooting convenience select vertical mixed flow pump as this engineering water circulating pump.Every unit
Configure 3 water circulating pumps.
Step 2: the arragement construction of circulating pump room is determined.
The high 12.6m of water tower catch basin water level (relative elevation, ground elevation are -0.30m, similarly hereinafter), water pump are received for a high position
Room is integrally predominantly located in ground or more, and the bottom (bottom surface) between water storage is lower than ground basal plane.Flume and diffused channel pressure-bearing
Arrangement is horizontally disposed with, and lower half portion is not in ground.
Pump house is indoor arrangement, built-in circulating water pump, hydraulic butterfly valve and corresponding hoisting facilities.
It is outdoor arrangement between water storage, between the logical maintenance of open top.Bulkhead gate and the filter of double flat plate is arranged in Parallel to the flow direction
Net, the interior corresponding hoisting facilities of setting of maintenance.
The absolute altitude of pump house operating layer is set, is required to be set to 8.0m according to Pump Suction water level.Based on pumping accident probability
It calculates, the absolute altitude that layer is operated between maintenance is 14m.
With pump house for staggered floor arrangement between maintenance, the top mark between water storage is higher by pump house operating layer 6m.
It with operating layer is that staggered floor arranges that civilwork engineering quantity is smaller between maintenance.Pump house operates layer lower than 6m between maintenance, follows
Ring Pump Axle is shorter, and water circulating pump operational safety is stable and equipment manufacturing cost is lower.
Hydraulic butterfly valve room in pump house, separates between water storage, butterfly valve room operate floor absolute altitude be 3.2m, butterfly valve without
Water logging risk, butterfly valve room use gravity feed drainage mode, no setting is required forced-ventilated facility.Above-mentioned measure ensures the stabilization of equipment
Operation, while significantly reducing project cost.
Step 3: recirculated water channel form is determined.
Connection is high-order to receive water tower and follows the recirculated water channel of pump house and catchment trench bottom extraction from high-order water tower of receiving, from more excessively high
Position tower ring group passes through herringbone column (passing through among 2 stabilizer blades of herringbone column), and half arranges on the ground.Recirculated water channel is single hole, In
Flaring plane bore at flat bank arc closes pressure-bearing.
Recirculated water channel water flow is horizontal flow direction, and the corner of no vertical direction, the arrangement head loss is small, system section
Energy.
Step 4: recirculated water channel is determined and the diffuser arrangement that follows pump house and be connected.
Using numerical simulation calculation means, is calculated and compared by the simulation to multiple diffuser schemes, it is final to determine: to expand
It dissipates section and reasonable diffusion angle is set；2 diversion piers of setting and 2 water conservancy diversion partition walls in diffuser, and water conservancy diversion partition wall has been determined
Length.
The head room of diffused channel end is lower than the head room 1m of front end.This kind of diffuser arrangement water distribution is equal
Even, water resistance is small, and flow-shape is stablized.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the above embodiments do not limit the invention in any form, all obtained by the way of equivalent substitution or equivalent transformation
Technical solution is fallen within the scope of protection of the present invention.
