Description
Technical field
The present invention relates to nuclear power field more particularly to a kind of nuclear power station shellfish catcher strainer cleaning plants.
Background technique
Nuclear power station SEC system exchanges heat final hot well system as nuclear island, be directly with core and safety-related major refrigeration,
Its major function can be discharged into the waste heat generated in nuclear island in an orderly manner under all operating conditions within the scope of design basis
In ultimate heat sink.
In the prior art, even if the strainer of shellfish catcher sets back purge system certainly, complicated Seawater environment is still
Strainer hole plug frequently is caused, it is simple to be difficult to dredge whole opening of sieves completely by backwash pressure difference and water flow, it is therefore desirable to
Manual cleaning is carried out to strainer during some cycles or High Pressure Difference, manually the blocked opening of sieve of dredging.But traditional is manual clear
Reason mode is not able to satisfy the duration demand of system, cannot also reach good cleaning effect.
Currently, the traditional shellfish supplementary set device strainer manner of cleaning up of nuclear power station mostly uses manual through-hole, air purging, soft brushes
It wipes, such manner of cleaning up is unable to satisfy timeliness demand under the limitations such as artificial time-consuming, duration pressure, energy consumption saving.Due to core
The particularity of power station cold source system is limited by unit operation nuclear safety codes, and clearance time is isolated in separate unit shellfish supplementary set device must not
More than 8 hours, therefore traditional manual cleanup strainer or dredges the mode of mesh and be difficult to meet that quick response, to restore cold source available
The requirement of property.Nuclear power station was once dredged mesh using the mode of artificial through-hole one by one, but established impurity lump and filter
Net form is integral, and manual through-hole is extremely difficult.The mode of manual through-hole generally takes a long time, in semi-enclosed space work condition environment
In, it to check blocking mesh one by one to intensive opening of sieve and dredge, it is clear that not be effective economic working method.And slow
Dredging rate under, the sudden and violent leakage for a long time of blocking strainer is among air, it will strengthens air-drying blocking lump and harden it more, instead
And it is unfavorable for cleaning task afterwards.
Further, since aperture of filter screen size is minimum, tamper is mostly the relative harders impurity such as small shell, silt, micro-
Many places are in gripping orientation when blocking in small filter opening, after even water plant detritus is accumulated in mesh, after a single system is arranged air to air,
Also it can air-dry rapidly and form new lump and pull blocking opening of sieve.In this case, simple use compressed air is purged
Tamper can not effectively be blown out, otherwise can also further air-dry other blocking impurity and form lump, cause vicious circle.It passes
Manner of cleaning up of uniting expends a large amount of human resources and time resource, and the work for being unfavorable for enterprise's cost efficiency is carried out.
By taking a stopping state of red H4SEC001FI in 2018 along the river as an example, it is the best in all previous for changing time stopping state
It is as follows to calculate strainer percentage of plugged hole for good situation:
Screen area: S net=1.625 ㎡
Strainer smallest aperture rate:
Strainer single hole diameter:
Strainer single hole area: the hole S=3.14*0.0012=3.14*10-6㎡
Mesh=153185 strainer total hole count N
Shell quantity in the tamper of collection: shell=2604 N (gross mass 12.4g)
According to the actual blockage of live mesh without being almost small shell, then it was initially believed that the shell quantity in gleanings is
=2604 are blocked for the blocking quantity of mesh: N
Plugging rate 1.70%
To sum up, during single strainer cleaning most ideally, up to more than 2600, blocking mesh, and it is faint
Plugging rate, which can directly draw high shellfish supplementary set device two sides pressure difference, influences its SEC system cold source availability.It can be analogized with this situation
In the case where blocking serious situation, strainer percentage of plugged hole can be up to 17% or so, it blocks mesh quantity and is even more than 3000 at that time
It is a.If dredge blockage mesh cannot be cleared up on a large scale within the limited duration, system will be unable to effectively be promoted logical after putting into operation again
Efficiency is flowed, it is thus regarded that cleaning failure.It can be seen that seeking convenient, the efficient manner of cleaning up of one kind is nuclear power station cold source guarantee
There is an urgent need to.
