embodiment 1:
boron recovery system Chu Peng workshop section cooling medium eddy flow process for purifying
1. implementing procedure
As shown in Figure 2.
2. key equipment
Complete tripping device in conjunction with micro-cyclone core-pipe subassembly and filterableness ash bucket is the key equipment in this technological process.Wherein, be inverted side by side vertical micro-cyclone core-pipe subassembly and be placed in tripping device housing, filterableness ash bucket is placed in micro-cyclone separation device top to be connected micro-cyclone underflow.Device processes amount is 10m
3/ h, physical dimension is Φ 600 * 2400.And top takes tube-sheet type sealing, employing activity ash bucket to be convenient to follow-up ash bucket replacing.
3. operation result
It is 1.16g/cm that disperse phase density is selected in experiment
3, the concentration resinous particle feed liquid that is 10ppm, under nominal situation, its flow is 10m
3/ h, operating temperature is normal temperature.Under operating condition, feed liquid can be carried the micro-solid particle polluters such as resin particle through boron removal bed except after boron, and the feed cavity at micro-cyclone separation device middle part converges the laggard core of cyclone in a subtle way pipe and carries out micro-cyclonic separation.Micro-cyclone utilizes the mobile centrifugal intertia force producing of fluid rotary to realize Separation of Solid and Liquid, and in overflowing liquid, disperse phase concentration of solid particles significantly reduces, and by connecting the underflow conduit of ash bucket in underflow chamber, is entered ash bucket by the underflow thing after significantly concentrating.Solid particle deposits gradually by slowly standing in ash bucket in ash bucket; And external phase clear water is discharged gradually from ash bucket side filter opening or top, and converge to upstream device with micro-cyclone overflowing liquid.Laboratory ON-LINE SEPARATION efficiency, all over 90%, meets the one circuit cools agent recycling accuracy requirement of nuclear power station reusable.Whole service process stabilization, even if there is obvious fluctuation, micro-cyclone and ash bucket sedimentation filtration efficiency normal.
Energy consumption aspect, the pressure loss of described micro-cyclone (being the pressure differential between micro-cyclone entrance and overflow vent) is about 0.15MPa, and for filtrator is separated, operation is more stable to be reduced energy consumption simultaneously and has also reduced the requirement to pump; The pressure drop that the sedimentation filter process of ash bucket produces does not impact actual process flow process.
Opereating specification and stability aspect, filtrator is different to the degree of purification of water quality when preliminary filtration and depth-type filtration, and only effective to being greater than the solid particle of filter opening size, and micro-cyclone detachment process is stable and wider to separated solid particle polluter particle diameter aspect range of choice, be conducive to the stable operation of follow-up operating mode.
4. technique effect
Traditional design for filtration elements pressure drop is conventionally at 0.25MPa, and the effect of its preliminary filtration and depth-type filtration is different makes whole detachment process unstable; With micro-cyclone separation device, replace filtrator, its advantage is, under the basicly stable condition of feed rate, in the pressure drop basic controlling 0.15MP that detachment process produces, the pressure drop producing in ash bucket does not have a significant effect to detachment process, has therefore reduced the requirement to pump consumption, has saved cost.This cover tripping device combines micro-cyclone High Rotation Speed separation feature separated with ash bucket standing sedimentation fast, and separation efficiency reaches 90%, can meet unit operation requirement completely.The topmost advantage of micro-cyclonic separation complete equipment shows following two aspects.
On the one hand, extend the continuous cycle of operation of equipment, while having reduced equipment replacement, caused the danger of radiation.For nuclear power generating sets, especially for containing the system of radiomaterial, filtrator also has radioactivity, and radioactivity filter element is changed while can regular differential pressure reaching setting value, and the single filter element replacing cycle is no more than 1 year substantially.The replacing of equipment is not only threatening the critical path of unit maintenance, the danger that more causes unnecessary radiating medium to reveal, and the unnecessary radiation dose of periphery staff and bring huge economic loss.By taking micro-cyclonic separation technique, appropriate design ash bucket physical dimension, can guarantee that the continuous cycle of operation of separation vessel reaches 10 years, and this relative filtrator has had obvious lifting less than the cycle of operation of 1 year.
On the other hand, reduce the radioactivity solid waste generation producing because of purification process, meet the energy-conserving and environment-protective that society is advocated.By adopting micro-cyclonic separation technique to substitute traditional filtration and separation techniques, purify radioactive solution, significantly reduced a large amount of solid wastes and the supporting standby redundancy that because of filter element replacing, cause and expended quantity, produced significant economic benefit and environmental benefit.Single useless filter core weight after filtration requires to be not quite similar depending on treatment capacity and processing accuracy, and what have weighs 100 kilograms, estimates that roughly the radioactivity solid waste that every 10 years single filter element replacings cause weighs one ton; And single ash bucket in complete tripping device of the present invention is no more than 100 kilograms, within 10 years, changes and once just produce the radioactive solid waste of 100 kilograms.Draw thus, by take micro-cyclonic separation technique not only avoided filter core repeatedly changed, reduced whole solid waste time, and meet the requirement that IAEA progressively reduces nuclear power station solid waste, produced positive environmental benefit; Also because of the minimizing that filter core expends, produce outstanding economic benefit simultaneously.
Study by experiment the complete reusable one circuit cools agent cyclonic separation process for purifying in boron recovery system of nuclear power plant of having simulated, its process operation is stable, simple operation, opereating specification are large, can realize rapidly and efficiently separated, separation efficiency remains at more than 90%, and pressure drop is no more than 0.15MPa, this measure has met on-the-spot unit operation requirement completely.Simultaneously, adopt micro-cyclonic separation technique to substitute traditional filtrator separating technology, not only the operating cost of unit will obviously be reduced, and will significantly reduce solid waste generation, also the stable operation cycle of system was brought up to 10 years by the filtrator epoch less than 1 year, not only reduce the workload of filter element replacing, also reduced the unnecessary radiation dose of operations staff, there is significant environmental benefit and economic benefit.
