Description
Technical field
The utility model relates to power plant and introduces seawater filtering device, particularly relates to a kind of automatic backwash marine growth gathering-device being arranged on the gutter port of export.
Background technology
In power plant, for the open cycle water system using seawater as cooling water source, pump entry is provided with one rotary sieve, is mainly used to marine growth larger in filtering sea and foreign material.
At the end of spring and the beginning of summer every year, in water, marine growth increases in a large number, and aquatic organism is very easily attached on rotary sieve jellyfish class, produces following adverse effect to the normal work of rotary sieve:
1, reduce the flush efficiency of the flushing water of rotary sieve, cause differential pressure before and after rotary sieve to raise very soon, rotary sieve flushing cycle shortens;
2, part jellyfish can pass through from rotary sieve directive wheel gap location with seawater, thus causes the differential pressure of secondary filter to rise, and causes circulating pump electric current to increase, motor power consumption increases, the cooling water inflow of condenser reduces, and affects condenser vacuum performance, unit heat economy is declined.
3, need cleaning personnel omnidistance uninterrupted cleaning when marine growth amount is large, otherwise gutter very easily blocks; But be difficult to when night shift realize.
4, the marine growth pulled out of rotary sieve is because having little time cleaning, and major part returns to forebay again, and the aquatic organism in forebay is constantly accumulated, and forms vicious circle.The cumulant of the marine growth that forebay is a large amount of crosses senior general makes rotary sieve forced outage, even causes the serious consequence of unit outage, and impact is normally produced.
Do not affect seawater proper flow in order to ensure pressure reduction before and after filter screen, avoid affecting unit and run well, substantially adopt labor cleaning's means to clear up the marine growth before filter screen at present, efficiency is low, and labour intensity is large.
