Risk is less, separating energy consumption is lower.
Embodiment
The present invention is expanded on further with reference to specific embodiment.It should be appreciated, however, that these embodiments are only used for
The bright present invention and be not meant to limit the scope of the invention.The test method of unreceipted actual conditions in the following example, generally
According to normal condition, or according to the condition proposed by manufacturer.Unless otherwise stated, all of percentage and number be by weight
Meter.
Embodiment 1:
Boron recovery system removes boron workshop section cooling agent eddy flow and purifies technique
1. implementing procedure
As shown in Figure 2.
2. key equipment
Complete separator in conjunction with micro- cyclone core-pipe subassembly and filterability ash bucket is that key in this technological process sets
Standby.Wherein, it is inverted vertical micro- cyclone core-pipe subassembly side by side to be placed in separator housing, filterability ash bucket is placed in micro- eddy flow
Separator top is to be connected micro- cyclone underflow.Equipment treating capacity is 10m3/ h, appearance and size is φ 600 × 2400.And push up
End takes tube-sheet type to close, and is easy to follow-up ash bucket using movable ash bucket and changes.
3. operation result
Experiment is 1.16g/cm from dispersion phase density3, concentration be 10ppm resinous particle feed liquid, under nominal situation
Its flow is 10m3/ h, operation temperature is normal temperature.Under operating condition, feed liquid removes after boron through boron removal bed that to carry micro resin broken
The solid particle polluters such as grain, the feed cavity in the middle part of mini-hydrocyclone separation device converges the laggard core pipe of cyclone in a subtle way and carries out micro- eddy flow
Separate.Micro- cyclone realizes separation of solid and liquid using the centrifugal intertia force that fluid rotary flowing produces, dispersion phase solid in overflowing liquid
Granule density is greatly reduced, and the underflow thing after significantly being concentrated enters ash charge by connecting the underflow conduit of ash bucket in underflow chamber
Bucket.Solid particle passes through slow standing in ash bucket and gradually deposits in ash bucket；And continuous phase clear water from ash bucket side filter opening or
Top is gradually discharged, and converges to upstream device with micro- cyclone overflowing liquid.Laboratory ON-LINE SEPARATION efficiency is all more than 90%, full
Sufficient nuclear power station reusable primary Ioops cooling agent reuses required precision.Whole service process stabilization, even if there being obvious fluctuation, micro-
Cyclone and ash bucket sedimentation filtration efficiency are normal.
Energy consumption aspect, the pressure loss (i.e. pressure differential between micro- cyclone inlet and overfall) of described micro- cyclone is about
For 0.15mpa, for filter separates, run more stable reducing energy consumption simultaneously and also reduce the requirement to pump；Ash
The pressure drop that the sedimentation filtration process of bucket produces does not impact to actual process flow process.
Opereating specification and stability aspect, filter differs to the degree of purification of water quality in preliminary filtration with depth-type filtration
Sample, and only to the solid particle more than filter pore size effectively, and micro- cyclone separation process is stablized and to detached solid
Granule foreign particle diameter aspect range of choice is wider, is conducive to the stable operation of follow-up operating mode.
4. technique effect
Traditional filter design pressure drop generally in 0.25mpa, it is preliminary filter different with the effect of depth-type filtration make whole
Individual separation process is unstable；Replace filter with mini-hydrocyclone separation device, have an advantage in that, in the basicly stable condition of feed rate
Under, within the pressure drop of separation process generation controls 0.15mp substantially, the pressure drop producing in ash bucket does not have obvious shadow to separation process
Ring, therefore reduce the requirement to pump consumption, saved cost.This set separator combines micro- cyclone high-speed rotation and quickly divides
From feature detached with ash bucket standing sedimentation, separative efficiency reaches 90%, is entirely capable of meeting unit operation requirement.Mini-hydrocyclone separation becomes
The topmost advantage of covering device shows following two aspects.
On the one hand, extend the equipment continuous cycle of operation, reduce the danger causing to radiate during equipment replacement.For core
Group of motors, in particular for the system containing radioactive substance, filter also has radioactivity, and radioactivity filter element can be determined
Phase or pressure reduction reach and are changed during setting value, substantially no more than 1 year single filter element replacing cycle.The replacing of equipment not only prestige
Coerce the critical path of unit maintenance, more cause the danger that unnecessary radiating medium is revealed, and periphery staff
Unnecessary dose of radiation and bring huge economic loss.By taking mini-hydrocyclone separation technique, appropriate design ash bucket is tied
It can be ensured that the continuous cycle of operation of separator reaches 10 years, this filter cycle of operation less than 1 year relatively has structure size
It is obviously improved.
On the other hand, reduce the radioactivity solid waste yield producing because of purification process, meet the energy-conservation that today's society is advocated
Environmental protection.Purify radioactive solution by traditional filtration and separation techniques are substituted using mini-hydrocyclone separation technique, significantly reduce because
A large amount of solid wastes that filter element replacing causes and supporting standby redundancy expend quantity, create significant economic benefit and
Environmental benefit.Single useless filter core weight after filtration requires to be not quite similar depending on treating capacity and processing accuracy, 100 public affairs that weigh having
Jin, the radioactivity solid waste that every 10 years single filter element replacings of rough estimation cause weighs one ton；And complete point of the present invention
Single ash bucket in device is less than 100 kilograms, changes within 10 years the radioactive solid waste once just producing 100 kilograms.By
This draws, not only avoids when repeatedly changing, reducing overall solid waste of filter core by taking mini-hydrocyclone separation technique, and
Meet the requirement that iaea gradually reduces nuclear power station solid waste, create positive environmental benefit；Simultaneously also because of subtracting that filter core expends
Produce prominent economic benefit less.
In the boron recovery system of nuclear power plant by experimental study full simulation, reusable primary Ioops cooling agent cyclonic separation is net
Metallization processes, its process operation is stable, simple operation, opereating specification are big, can achieve and rapidly and efficiently separates, separative efficiency remains
More than 90%, and pressure drop is less than 0.15mpa, and this measure has fully met live unit operation requirement.Meanwhile, using micro- eddy flow
Separating technology substitutes traditional filter separating technology, not only by the obvious operating cost reducing unit, and will be greatly reduced
The stable operation cycle of system was also brought up to 10 years less than 1 year by the filter epoch, not only reduces by solid waste yield
The workload of filter element replacing, also reduces the unnecessary dose of radiation of operations staff, has significant environmental benefit and economic effect
Benefit.
