Description
Technical field
The utility model relates to sewage treatment area, particularly, the utility model relates to a kind of comprising can the circulation for generating set of the solid matter filtering device of solid matter in filtered water, and this circulation is mainly used in the cooling of the generating set in thermal power plant.
Background technology
In power plant; especially in thermal power plant; Turbo-generator Set is usually using seawater as Municipal Sewage for Circulating; but; owing to there is marine growth and the solid sundries such as Polypropylence Sheet, polybag in seawater; therefore often there will be marine growth or solid matter blocking rotary sieve, make rotary sieve compressive deformation cause the problem of damage.For the power plant be arranged in the more marine site of operation fishing boat, because its intake distance bank is nearer, therefore, marine growth is relatively less, the principal element of blocking rotary sieve is solid sundries, the source of these solid sundries is a lot, as Polypropylence Sheet, polybag easily drop in the sea by operation fishing boat, the polybag of land easily by wind to nautical mile etc.When the solid sundries on rotary sieve is wound around more, the minimizing of the quantity of circulating water in order to cooling that circulation is supplied to generating set even stops providing recirculated water to generating set, thus cause generating set to be cooled preferably, in this case, generating set load shedding operates, even may occur that generating set stops the phenomenon of generating, larger threat is caused to the safety of generating set.
In prior art, adopt the method increasing the equipment such as trash rack in the front of rotary sieve with in advance by most of solid impurity blocking filter, make it possible to the solid impurity minimizing arriving rotary sieve.Along with the growth of service time, the solid sundries such as the Polypropylence Sheet above trash rack, polybag are piled up gradually, and after being stacked into a certain degree, the quantity of circulating water that can arrive generating set reduces, and therefore, is necessary to carry out periodic cleaning to trash rack.But because trash rack is fixedly mounted on intake place, therefore the cleaning of trash rack needs to rely on trash rack to climb dirty machine.But climb bucket and to coordinate with trash rack owing to climbing dirty machine there is gap (about ± 2mm), therefore bucket is climbed when grid general work, the thin foreign material of the walls such as Polypropylence Sheet polybag are unavoidably left in the fit clearance position in rake teeth and grid face, trash rack is climbed dirty machine and can only do not salvaged by the floating thing such as marine growth, wood of trash rack large, works hardly for Polypropylence Sheet, polybag etc.Therefore, these can not be deposited on trash rack by the solid sundries of climbing the cleaning of dirty machine, and along with the amount of piling up increases, trash rack easily blocks, and after blocking, marine growth easily grows above.In addition, due to blocking Posterior circle water trash rack position only water on the lower, therefore have marine growth reside in above growth, it on, the marine growth of growth also continues blocking trash rack, forms pernicious circulation.
Therefore, need to provide one effectively can avoid marine growth on trash rack, solid sundries overheap, and be convenient to the solid sundries filtering device of regularly cleaning.
