Description
Technical field
The utility model belongs to nuclear power station flume and blocks dirty technical field, and in particular to a kind of flume garbage barrier net.
Background technology
The cooling water of nuclear power plant's recirculating cooling water system and essential service water system and important equipment is with nuclear power plant
Intake as water source, the quality of intake operating status directly affects safe operation and the reliability of power plant.
In recent years, with east tourist industry, the fast development of aquaculture, the variation of the coastal marine eco-environment, power station
SEC/CRF system intakes surrounding waters threatens the small-sized marine growth of power station water intaking safety more and more, as (size exists shrimp
Within 3cm), jellyfish etc., existing intercept process equipment such as garbage barrier net, mechanical grille, filter drum in power station etc. cannot cope with small-sized sea
The threat of biological large-scale outbreak.Occur both at home and abroad a lot of because intake blocking leads to power station unit drop power or shutdown thing
Part directly contributes huge economic losses and influences npp safety related system.For such situation, to ensure power station water intaking peace
Entirely, the marine growth for influencing power station water intaking safety is intercepted and is used as special subject study by many nuclear power stations, including quick-fried from marine growth
The source of hair, mechanism have carried out numerous studies, but achievement in research at this stage only exists in theoretical research stage, and there are no form one
It covers perfect professional standard and thorough solution and is limited only to be transformed the passive of upgrading to existing interception facility
Intercept pattern.
Conventional solution is the bottom of blocking in the nuclear power station flume front end setting together garbage barrier net with floating drum positioning device
Portion and both sides setting anchor block and anchor pier.The structure type simple structure, it is of low cost, replace it is convenient, can effectively prevent it is various compared with
Rubbish, the sundries of large volume enter pumping plant intake, and pumping plant water intaking grid, filter drum is avoided to block.But to occurring recently such as hair
The smaller marine growth of the bodily forms such as shrimp, jellyfish, phaeocystis cannot play good interception function.It is mainly stranded existing for the structure at present
Difficult and defect is as follows：(1) many small-sized marine growths it is small, without very strong floating capability, drift with the tide, inlet channel compared with
Under the drive of high speed water flow, block mesh is easily caused to block, in order to not influence the conveyance capacity of inlet channel, need it is regular and
Timely mesh sheet is replaced in cleaning, and conventional block is difficult to realize quickly clean folding and unfolding mesh sheet and the human cost of more draping is higher；(2)
Conventional garbage barrier net mostly uses anchor block and floating drum and block is fixed, and structures under wind wave ability is weaker, poor in sheltering condition
Inlet channel front end, under the action of wind, wave, stream, block stressing conditions are complicated, especially when marine growth is largely broken out, merely
Hauling type structure, for the angle of stress, design margin evaluation is relatively low；(3) conventional garbage barrier net is only capable of intercepting water body table
Layer floating material can not achieve tunneling boring interception.As between block and inlet channel slope, riverbed face there is also gap loophole, this
It is respectively formed the channel that marine growth enters hydro plant intake a bit；(4) conventional garbage barrier net mostly uses the material of nylon wire, in ocean ring
The performance of durability and anti-sea organism attachment under border is poor, need to often replace, maintenance cost is higher.
