Abstract
The invention provides a kind of double medium filtration system with anti-halobios adhersion function.It includes screen pack, spud pile, cursory and five parts of lead body.Screen pack includes outer filter and inner filter screen, and filter screen device is on spud pile, and it is cursory that filter screen top is installed, and lead body is installed in bottom.Outer filter is 5*5mm Dense mesh screens, and rectangular, inner filter screen is the dictyosome that grid is 5cm*5cm, and its kernmantle is made up of interior braiding layer, middle reinforced rib, three layers of outer braiding layer.Screen pack is all handled by anti-halobios adhersion and water repellent.Under the impact and traction of current, outer filter filtering water channel is biological, by the dirt removal on screen pack, and inner filter screen intensity is high, and outer filter is played a supportive role.The features such as present invention has intensity height, resistance to erosion, good strainability, water repellent, anti-halobios adhersion, available for the filtering to foreign matter in nuclear power plant's recirculated water or biology.
Description
Technical field
The present invention relates to the filtering of the circulation organism in water of nuclear power plant, belong to water channel foreign body filtering field.
Background technology
In the recent period, nuclear power plant of China there occurs several due to marine organisms or ocean foreign matters from being blocked water intake system to influence to take
The event of water security.In some typical events in recent years that State Bureau of Nuclear Safety arranges, including：Cause because sea shrimp pours in intake
Reactor emergency shut-down run case, pour in because of a large amount of Haiti melon bursts intake caused by unit cause shutdown to run thing
Part, pour in because of a large amount of jellyfishes circulating water filtering system intake and cause unit shutdown run case, seawater intake wheat straw bar to block up
Fill in run case and because of debris sanitary fill and enter nuclear plant water intaking mouthful, cause circulation to rouse network sale fracture and often
Rule island unboiled water system air inlet causes unit downrating event.
The blocking of marine organisms or foreign matter can cause drop power or even the shutdown of unit, even can be to ultimate heat sink when serious
Availability constitute a threat to, need to attract great attention.In consideration of it, we are in the urgent need to that may be present to water intaking and filtration system
Design or Construction Problems are improved, and develop a kind of efficient water channel anti-halobios adhersion filter net system, and enhancing water channel resists sea
The ability of foreign biological or foreign matter.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of two-layer equation filter net system with anti-halobios adhersion, solution
Certainly filtering Netease aufwuch, the problem of the cleaning frequency is short, service life is short.
The technical solution adopted for the present invention to solve the technical problems is：A kind of water channel anti-halobios adhersion screen pack system is provided
System, including screen pack, spud pile, cursory, lead body, screen pack include outer filter and inner filter screen.The present invention by existing in advance
Water-bed vertical implantation spud pile spaced apart, outer filter and inner filter screen are fixed between two spud piles, pass through net
Body is realized to the biological filtering of water channel, easily facilitates the impurity in people's cleaning recirculated water.
Described screen pack, outer filter is rectangle, and grid is 5*5mm Dense mesh screens, and nettle is thin, mesh is small, can be effective
Interception water in debris.Inner filter screen is 5cm*5cm dictyosomes into size of mesh opening by high-performance fiber braiding, and nettle is compiled by interior
Tissue layer, middle reinforced rib, three layers of outer braiding layer are composited, and nettle is thick, mesh is larger, and intensity height can resist current scour.Outside
The size of metafiltration net is consistent with inner filter screen.Two layers of dictyosome is parallel to be fixed between spud pile.
The screen pack is all by anti-halobios adhersion, water and oil repellant processing.
Described screen pack dictyosome installs cursory offer buoyancy at top, and lead body is installed in bottom.
Beneficial effect
As a result of above-mentioned technical scheme, the present invention compared with prior art, has the following advantages that and good effect：
（1）Nettle is made using high-performance fiber, and intensity is high, and ageing-resistant, corrosion-resistant, service life is long；
（2）Dictyosome ectonexine sieve meshes are not of uniform size to be caused, can high efficiency filter water channel biology, impurity etc.；
（3）Dictyosome passes through anti-halobios adhersion, water repellent.

Embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
Embodiments of the present invention are related to a kind of two-layer equation filter net system of anti-halobios adhersion, including screen pack, fixation
Stake, cursory and lead body, screen pack include outer filter and inner filter screen.
Described screen pack is that ectonexine dictyosome is by a diameter of 3mm nettle through binode by outer filter and inner filter screen
Netting machine knitting forming, sets outer layer mesh size as 5 × 5 mm, and internal layer mesh size is 5 × 5cm, inner filter screen used
Nettle is formed by high-strength high-modulus polyethylene braiding, then with middle reinforced rib of the carbon fiber as inner layer net body.It is last internal
Outer filter carries out anti-halobios adhersion and water repellent processing, can avoid the pollution dictyosome of ocean debris, tiny organism etc., two layers of filter screen
Between fixed dress, it is cursory that dictyosome top is installed, and lead body is installed in bottom.
