A kind of efficient sewage-absorbing filter
Technical field
The present invention relates to art of filters, in particular to a kind of efficient sewage-absorbing filters.
Background technology
When N-1 platform filters work, by the filtration of cartridge surface, the impurity more than its filtering accuracy is blocked fluid
It cuts outside, liquid enters downstream by strainer after residual fluid is filtered, and filter is after using a period of time, filter core table
Face can accumulate one layer of impurity, and the pressure difference of filter core front and rear sides increases, to trigger Filter Back Washing.Traditional method is:It will
1 filter is placed in backwash state, and remaining N-1 platforms continue to filter.Gas auxiliary backwash:External high pressure gas is introduced, it will
This waits for that the fluid inside backwash filter flows counterflow through filter core, and fast evacuation removes the cake layer of cartridge surface accumulation;Filter
Liquid backwashes afterwards:The filtered fluid of N-1 platforms is introduced this and waits for backwash filter, flows counterflow through filter core, fast evacuation will filter
The cake layer removing of wicking surface accumulation;Gas auxiliary backwash or filter after liquid backwash when, big flow liquid under pressure,
Back through the cartridge surface for needing backwash, cake layer is fallen off.Therefore, it is required for using large flow fluid in this way, cause anti-
Detergent liquid amount is bigger.Due to containing colloid or pitch metallic substance in fluid, they can be adhered to cartridge surface, cause to backwash
Effect is bad, according to the requirement of technique, can introduce the clean fluid that can dissolve these stickums and be soaked for a period of time, then
It backwashes again, this part clean fluid treats as waste oil freshening again, and energy consumption is caused to increase with cost.Meanwhile even if big flow
Under pressure back through the cartridge surface for needing backwash, since the surface area of whole branch filter core is larger, it is distributed in number
The flow velocity for measuring numerous cartridge surfaces for needing backwash can be relatively slow, according to Bernoulli equation it is found that being lost in the pressure of cartridge surface
Power is relatively low, unclean so as to cause filter-core back-flushing, i.e. regeneration is not thorough, for a long time, it is necessary to do filter core and be cleaned outside device, i.e.,
It is first removed out of container, physics and chemical method is then used to wash.In this way, when filter core is cleared up, not only soiling solution amount is big, increases
Add energy consumption and cost.
