Background technology
Power system cooling circulating water takes away the heat of equipment and product by heat exchanger or spray；And itself temperature
Decline be to evaporate realization in cooling tower by cooling water.After usage time is long, four kinds of ratios occur in cooling circulating water
More serious harm problem：
1st, the phenomenon of deposition is blocked：Cooling circulating water operationally, the suspended solid impurities in water can be deposited on pipeline and
Heat-exchanger surface, nozzle for cooling tower, filler can be blocked；
2nd, scale formation：The salt such as the calcium carbonate in cooling water can the fouling on pipeline；
3rd, corrosion phenomenon：The meeting of the equipment such as the carbon pipe in circulation may be by aqueous corrosion；
4th, problem of bacteria：Bacterium in recirculated water may amount reproduction, cause the aggravation of above three kinds of situations.
For the first situation solved by filter；Three kinds of situations next are generally by the corresponding chemicals of addition
The methods of solve, most of on the market at present is to apply slow-release scale inhibitor, alleviates the speed of corrosion to a certain extent；But mistake
More bacterial reproduction, the dosing of circulation, secondary pollution can be produced to follow-up water body, follow-up total phosphorus and total nitrogen can continue to raise, dirty
The equipment investment of newly-increased dephosphorization is needed in terms of water process, the bactericidal agent of secondary superposition can lift apparatus capacity.
For filtering this means, conventional method includes 3：
1 is to build a filtering ponds on the ground with cement or steel.Its major defect is taken up an area, it is necessary to do engineering, and recoil water wasting, instead
Poor filtration effect when rushing bad, cost is not cheap, and its advantage is that filtering and recoil need not be electric, energy resource consumption is saved, when general
Wait good filtration effect；
2. mechanical filter, its shortcoming is to take up an area big, equipment requiring installation during installation, water wasting during recoil, when recoiling bad
Poor filtration effect, it is very inconvenient to change sand.Advantage is cheap, good filtration effect when general；
3. long fibre filter：Several years ago just occur, its filter medium is long fibre, and in filtering, long fibre is crushed on
Together, filtration；Long fibre is straightened during recoil, is advantageous to recoil.Its shortcoming is that cost is expensive, is taken up an area big.Transport for a long time
There is recoil not exclusively in row, and filter life is short, underfed, is forced to change long fibre, and recoil water wasting.
In consideration of it, all less suitable recirculated cooling water of three of the above processing mode, mainly investment are big, filtering accuracy is not
Enough, backwash water consumption, filter effect is unstable, is not reaching to the full-automatic degree of left unguarded running.

Portion.
The two sides of lamination 13 is provided with groove 133, and the wherein groove of one side and the trench angles of another side is different, is not flat
Row state.As shown in figure 5, the groove and A in A faces1The trench angles in face are different, as shown in fig. 6, lamination 13 adjacent two up and down
Different size of filtration channel 131, the precision of laminated filter 1 can be collectively formed in the different filtered points of the groove 133 in face
20-50 microns can be accomplished, the impurity 132 more than 100 microns is removed substantially.
Operation principle of the present utility model is as follows：
Sewage enters from water inlet pipe 6, by two position three-way valve 8, enters laminated filter 1, sewage from the second intake-outlet
Full of the space between the lamination 13 and cartridge wall 11 being stacked, lamination 13 is inside and outside to form huge pressure differential, lamination 13
Between gap diminish, the total height of lamination 13 becomes short, and the groove 133 between lamination 13 intersects, and it is logical to form a series of unique filterings
The in-depth filtration unit in road 131, water from the periphery of lamination 1 through being flowed through in groove 133 into enclosing in lamination 13, the impurity 132 in water
Being stuck in groove 133 can not be by the way that water after filtering is gone out from the first intake-outlet, is discharged by outlet pipe 4.Program has been arrived to set
Fixed backwashing time, water purification enter from outlet pipe 4, by two position three-way valve 8, enter laminated filter from the first intake-outlet
1, a part is partly into water column 14 from water hole 141 full of being enclosed in lamination 13 and sprays directive lamination 13, and due to lamination
The pressure differential of 13 inner peripherals, the gap between lamination 13 become big, and the total height of lamination 13 is uprised, and buffer spring 12 is compressed, water from
Enclosed in lamination 13 through being gone out between lamination 13 with larger pressure, the impurity being stuck in groove 133 can be rinsed and gone out, water is taken
Go out from the second intake-outlet with a large amount of impurity, discharged by blow-off pipe 5；Of course, it is possible to open check valve, by compressed air cylinder
Air in 22 enters lamination mistake by air recoil pipe 21, four-way valve 7, connecting tube 3 with certain air pressure from the first intake-outlet
Enclosed in filter 1 with water column 141, due to enclosing the reason of peripheral pressure difference in lamination 13, buffer spring 12 compresses, between lamination 13
Gap becomes big, and gas sprays directive lamination 13 from the water hole 141 of water column 14, and air blows brush between lamination 13 with certain pressure
Impurity on groove 133, air carry impurity and gone out from the second intake-outlet, are discharged by blow-off pipe 5.Certainly, program can be set
4 kinds of backwash modes are counted into, the 1st kind is only to be backwashed with water；2nd kind is only to be backwashed with compressed air；
3rd kind is with water+compressed air while backwashes；4th kind is alternately backwashed with water and compressed air, and user can basis
Need to be selected.Laminated filter 1 works under 10 kilograms of pressure differences, and impurity leakage will not also occur, and filtering is not thorough
Phenomenon occur.To make water supply uninterrupted, it is asynchronous to set the backwashing time of each laminated filter, when a lamination
In backwash, other laminated filters still work filter, are backwashed in turn.Gas in outlet pipe 4 can be from letting out
Released in air valve 9, when compressed air cylinder 22 needs exhaust, after the air bleeding valve of compressed air cylinder 22 is opened, gas also can be from letting out
Released in air valve 9.
The technical scheme provided above the utility model embodiment is described in detail, used herein specifically
Individual example is set forth to the principle and embodiment of the utility model embodiment, and the explanation of above example is only applicable to help
