Description
Technical field
The utility model relates to the nuclear power station technical field, particularly relates to the special-purpose deflector array formula of a kind of nuclear power station desalination device filter.
Background technology
Charging aperture and the discharging opening of the anion bed of the water treatment facilities desalination device of existing nuclear power station, cation bed, wet bed all are equipped with the filter device, also referred to as the water cap, be used for stoping ion exchange resin to pass through, but the water after purification is passed through, and obtain water purification with this.
Existing filtering head version has wrapping wire type, laminated type etc.Wrapping wire shape filtering head cracky need to be through the spot welding solid welding on skeleton during steel wire wound, and welding deformation is large, and intensity of steel wire is low, and is yielding, and the gap between steel wire and steel wire is difficult to control.The chimney filter of lamination shape filtering head is formed by the filter disc stack combinations of some same structures, the cross of every filter disc is symmetrical to all having, with filter disc be holistic small boss, thereby after some stack combinations axially form four muscle, being connected between two forms four of equi-spaced apart along circumference and crosses the water gap, this device is compared not cracky with wrapping wire shape filtering head, and its defective is:
1. the height due to small boss on the make very easily produces deviation, and the water gap excessively between sheet and sheet leans on the small boss touch controls at four positions to form, will make like this water gap size uneven, place bigger than normal, gap can produce the phenomenon that ion exchange resin runs off.
2. owing between every adjacent two filter discs, four small boss being arranged, this has also reduced the permeability rate of filtering head.
For solving the problem that caused water gap size inequality because of the deviation of small boss size, the patent No. be 200820040698.X's " filter head apparatus of nuclear plant desalting device " provide a kind of fine finishining the formed overall structure of crossing water gap and isolation bar, to guarantee the uniformity in current gap.But the defective of this scheme is:
The manufacturing procedure of chimney filter loaded down with trivial details and processing required precision very high, difficulty of processing is corresponding higher;
2. due under the long-term vibration of water impact to filter disc, fatigue break can occur in indivedual filter discs under high-frequency bending repeatedly.Due in such scheme, all filter discs are an integral body that can not be split, filter disc do not have to change separately leeway, the breakage of any one filter disc will make the whole chimney filter that gets through retrofit become waste product.This waste beyond doubt.And to avoid this situation to occur, only have the thickness that increases filter disc under the prerequisite that does not change this scheme technical characterictic.Due to the filtering head limited length, the thickness that strengthens filter disc has reduced the quantity of crossing the water gap beyond doubt, can greatly reduce so again the permeability rate of filtering head, has reduced the service efficiency of device.
3. due in such scheme, all filter discs are an integral body that can not be split, and this brings very large difficulty for the regular work of unpicking and washing, decrease unpick and wash the efficient of work.
For addressing the above problem, the patent No. is that 201010148989.2 " special isometry type desalination device filter head for nuclear power plants " adopts the filter disc of dististyle and annular to replace overlapping mode, to guarantee the uniformity of the width of crossing the water gap between every adjacent two filter discs.But this scheme has produced again following several point defects:
1. because every dististyle is all fixing by socketing sheet and vertically running through the fixing drawknot bar in three positions of desalination device filtering head integral body, these three dististyles that just determined every one deck are in identical position in the horizontal direction, therefore, overlapping dististyle vertically can form tibet cinnamon bark filter, the part that filter disc is in this tibet cinnamon bark position can possess stronger rigidity, and the remainder of filter disc is due to the support without any other members, its rigidity a little less than, therefore, the stiffness distribution of each piece filter disc is uneven.Under the long-time impact of current, this stiffness distribution inequality can make filter disc because of long-term dither fracture.This has reduced durability and the impact strength of device undoubtedly.
2. the described dither that occurs of filter disc service life of not only having reduced filter disc, the more important thing is, because its elastic deformation meeting that occurs changes gap width between adjacent two filter discs, so just reduced the filter effect of ion exchange resin in vibration processes.
3. because the end of the positioning bar in such scheme and each dististyle is close to, its arc length has surpassed the length of dististyle simultaneously, so on the one hand water outlet has been caused certain stopping, has reduced the water outlet efficient of device; Simultaneously, positioning bar only can play restriction to the horizontal level of dististyle, and three drawknot bars have possessed this effect, and therefore, the existence of positioning bar has also caused the waste on the material.Increased the manufacturing cost of device.
4. the lamellar body that is made of dististyle and drawknot sheet due to each piece must with its three cover ring plates simultaneously, be enclosed within on three drawknot bars that are in active relationship with it exactly, have higher assembly precision requirement, so assembling process efficient be not high.
5. in this device, the filter disc and the dististyle that are superimposed are compressed, what rely on is three drawknot bars that are positioned at the device middle part, do not impel its edge to combine closely and have any force application structure in the outer edge of dististyle and filter disc, such application of force is uneven, can cause the height and position generation difference at the lamellar body that consisted of by dististyle and drawknot sheet its middle part and edge, thereby cause distortion to a certain degree, and this distortion is very disadvantageous for the uniformity in gap between adjacent filter disc.Therefore also can reduce the filter effect of this device.
6. in this device, water inlet place is merely able to rely on the limited water hole of three areas of opening on top board to pass through current due to stopping of top board being arranged, and this has reduced the water efficient excessively of device undoubtedly; If but increase the perforated area of three water holes, and certainly will reduce again the intensity of top board, affect it to pressure and the fixed effect of filter disc and dististyle, this is also a pair of insoluble contradiction.
